Meizu 16th deep dismantling： copper pipe heat dissipation + double-layer middle frame

　　As the latest flagship mobile phone released by Meizu, Meizu 16th uses the Qualcomm Snapdragon 845 processor, and uses copper tube heat dissipation in the mobile phone heat dissipation, so that the mobile phone has a better heat dissipation effect, and the mobile phone runs more stably and smoothly during games. Meizu 16th has also changed its design, not using a metal machine design, but using a 3D four-curved glass back cover, and controlling the thickness of the fuselage to 7.3mm, making it the thinnest under-screen fingerprint recognition mobile phone on the market.

　　Meizu 16th uses a glass back cover, and the back cover is fixed on the fuselage with double-sided tape, so when dismantling the back cover, it needs to be heated with a hot fan, and the hot double-sided tape can be melted to separate the back cover.

　　After heating, you can use a pick to separate the fuselage of Meizu 16th. Since the back cover is made of glass, the separation process should be very careful to avoid damage to the back cover glass.

　　The internal deconstruction of the Meizu 16th can be seen by separating the back cover. The PCB of the Meizu 16th also has a protective cover covered with plastic.

　　Meizu 16th uses a classic three-stage design, the top of the phone main board, the middle is the battery, the following is the small board, this design for Meizu to have been quite mature.

　　The back cover of Meizu 16th has been repeatedly polished, and the nano-scale 7-layer vacuum coating technology has been applied to the glass, allowing the 16th to achieve a nearly ceramic-like texture.

　　Open the protective cover of the bottom small board to see the small board PCB of Meizu 16th, which is mainly responsible for the connection of various interfaces of Meizu 16th and the connection of the external speaker of the mobile phone.

　　The small board of Meizu 16th also has an important function, which is to connect the horizontal linear motor mEngine of Meizu 16th to achieve a richer vibration effect.

　　Meizu 16th still continues this mEngine design and has been upgraded to bring a new algorithm that automatically adapts the touch according to the scene, provides feedback such as simulated heartbeat, scroll wheels, etc., and more ringtone music rhythm vibration.

　　The upper PCB of the Meizu 16th is also covered with a protective cover, and it can be seen that the dual camera of the Meizu 16th is the lower camera, which is the main camera.

The main board shield of Meizu 16th is covered with a graphite heat-conducting film, which allows the heat of the main board chip to be brought to the fuselage.

After taking out the main board of Meizu 16th, you can see the heat conducting tube on the middle frame of the mobile phone, and the CPU position on the main board is coated with thermal grease.

　　After removing the main board and battery, you can see the deconstruction of the middle frame of the mobile phone. Meizu 16th uses an aluminum alloy middle frame. The aluminum alloy material is lighter and is currently the material used in the middle frame of the mobile phone.

　　There is an opening in the middle frame of the mobile phone. Here is the under-screen fingerprint recognition module of Meizu 16th. Meizu rotates the fingerprint recognition sensor at an angle of 13.7 to eliminate moiré patterns. Therefore, the stacking of internal components of the mobile phone needs to be redesigned.

　　There is a heat conducting tube embedded in the middle frame. The position where the heat conducting tube contacts the CPU uses a whole piece of copper sheet to increase the heat conducting area. Meizu customized a 0.4mm thick heat dissipation copper tube. When the mobile phone is higher than the critical temperature, the water vapor in the heat dissipation copper tube will follow the capillary structure to take heat away from the main board. And when the water vapor cools down and liquefies, it will start to circulate back, which can bring better heat dissipation effect.

　　In addition, the middle frame of the mobile phone has a layer of copper foil in addition to the aluminum alloy material, which can better absorb the heat on the main board of the mobile phone and achieve better heat dissipation effect.

　　Meizu 16th built the handset into a small gap at the top of the fuselage, reducing the front opening of the fuselage, maintaining Meizu’s consistent minimalist and symmetrical design language, while also making the whole machine more visually integrated.

　　Meizu 16th main board shielding cover can not be removed, this design advantage is to make the shield cover become thinner, bad place is to increase the difficulty of maintenance.

　　The back of the main board is mainly the CPU and power module of the mobile phone, and the shielding cover is also attached with graphite heat conduction stickers, and the shielding cover here cannot be removed.

Tear off the heat conducting sticker at the CPU position to see that the CPU of the mobile phone is also coated with silicone grease, which is to increase the heat dissipation effect of the mobile phone.

　　The CPU can be seen by wiping off the silicone grease. The Meizu 16th uses a Qualcomm Snapdragon 845 processor, and the processor and the memory chip of the mobile phone are double-stacked, so only the memory chip of the mobile phone can be seen. The CPU is soldered under the memory chip, and double-stacking can reduce the PCB area occupied by the chip.

　　Meizu 16th uses a 20 million pixel front-facing camera. Since the forehead position of Meizu 16th is only 7mm, the general front-facing camera module cannot be installed on Meizu 16th. Meizu specially customized the world’s smallest front-facing camera module for Meizu 16th. Customized design from hardware and optical components, and finally created the world’s smallest front-facing camera module, so that the forehead position of Meizu 16th can have such an ultra-narrow design.

　　Meizu 16th uses 12 million + 20 million pixel camera design and uses ring LED fill light to enhance the photo experience. At the same time, the 16th uses Sony IMX380 + IMX350 sensor, which can provide 3x lossless zoom and large aperture blur effect. The IMX380 sensor is also used on Meizu 15. This CMOS has been tuned by Meizu and used on Qualcomm Snapdragon 845 ISP to bring better shooting results.

　　Through disassembly, it can be seen that the internal workmanship materials of Meizu 16th are quite excellent. In particular, the heat dissipation design of the mobile phone is very careful. A layer of copper foil is added to the middle frame, and a graphite thermal conductive film covers the PCB. At the same time, a heat conducting tube is used to dissipate heat. Moreover, silicone grease is also applied to the position of the CPU to enhance the thermal conductivity effect. Such a design is relatively rare. In addition, the internal stacking of the entire mobile phone is quite careful, the purpose is to reduce the thickness of the mobile phone and bring a better feel. Overall, for a flagship mobile phone of 2698 yuan, such workmanship materials are still quite valuable.

The national team finds the right direction to start the reform of China volleyball in the domestic league.

Jingbao Sports | Reporter Zhuo Ran
In 2022, the first year of the Paris Olympic cycle, China men’s and women’s volleyball teams frequently appeared in the international arena, exercised their teams against the world’s top players, made some achievements, identified their goals and directions, and at the same time found their own shortcomings and recognized the gap. Generally speaking, the upward climb of men’s and women’s volleyball in China, which is in the alternation of old and new, faces both opportunities and challenges.
The women’s volleyball team is gradually on track.
The shadow of losing the Tokyo Olympic Games still exists, Zhu Ting and Zhang Changning are absent, Yan Ni and other veterans retire … Cai Bin took over the coach of China women’s volleyball team in a difficult situation. This year, under his leadership, the tenacious China women’s volleyball team once again proved the powerful strength of the women’s volleyball spirit.
The 2022 World Women’s Volleyball League is the first show of the new China women’s volleyball team under Cai Bin. In the first competition week, China women’s volleyball team reversed the Dutch team, defeated the Turkish team and defeated the Italian team, and even scored 3 wins and 1 loss, which was remarkable. In the following two races, the performance of China women’s volleyball team was mixed. In the end, it broke into the quarterfinals of the World Women’s Volleyball League with 12 games, 8 wins and 4 losses, and achieved the set goal. Although it lost to the Italian team which won the championship in the quarter-finals, it missed the semi-finals, but in the debut of this new women’s volleyball team, this team made people see the impact and hope.
Coach Cai Bin bluntly said after the game that the 13 matches of the World Women’s Volleyball League were very valuable experiences, which helped the team find the direction of efforts. Although the team is not mature enough, Jin Ye and Wang Yun, two Mesozoic main attackers from Beijing Automobile Women’s Volleyball Team, dared to fight and fight to make up for the vacancy on the main attack line of this team as much as possible. Li Yingying, Gong Xiangyu and Yuan Xinyue, through constant tempering, have also taken on the offensive and defensive responsibilities of the team.
Before the start of the World Women’s Volleyball Championships, perhaps not many people can say with great confidence that the goal of China women’s volleyball reaching the quarterfinals can be achieved with a high probability. In the World Championships, China women’s volleyball team defeated Argentina, Colombia, Japan and the Czech Republic with four scores of 3-0 in the group stage, and it was not until it met the powerful Brazil team in the final round that it swallowed its first defeat in the World Championships. In the semi-finals, China women’s volleyball team beat Puerto Rico lightly, narrowly defeated the Netherlands and defeated the Belgian team in five games, and successfully advanced to the quarterfinals, achieving the set goals. Facing the Italian team again in the quarter-finals, the China women’s volleyball team was weaker than its opponents in all technical aspects, lost 1-3, stopped in the quarter-finals, and finally ended the journey of the World Championships with the sixth place.
From the World Women’s Volleyball League to the World Women’s Volleyball Championships, in just a few months, this China women’s volleyball team has shown its own progress, played its morale and self-confidence, and let the outside world see a brand-new mental outlook. However, in the confrontation with the world’s top teams such as Italy and Brazil, the team’s inexperience, unstable state and many mistakes are also exposed.
Cai Bin said in an interview after the World Championships that young players have grown up rapidly through the experience of the World Championships, with both regrets and gains. Facing the top teams in the world, China team should continue to tap its potential and build a system of balanced attack and defense.
In 2022, we saw the potential and hope from this China women’s volleyball team. In 2023, intensive international competitions such as the World Women’s Volleyball League, the Asian Games and the Paris Olympic qualifiers are waiting for the girls, expecting China women’s volleyball team with fine traditions to achieve new success.
Men’s volleyball team wins Asian championship again
Looking back on 2022, it is a great encouragement for China men’s volleyball team and China volleyball team that China men’s volleyball team won the Asian Cup again after 10 years, which can even be called a big event in domestic sports. However, in the eyes of many fans, if we want to rank the surprises brought by China men’s volleyball team this year, it may be more exciting that they beat the powerful Brazilian team in the World Men’s Volleyball League.
In recent years, there are not many opportunities to compete in the international arena, and the China men’s volleyball team has rarely performed brilliantly. In the 2022 World Men’s Volleyball League in Brazil, China men’s volleyball team lost all three games, and the whole team was in the haze of defeat. In the final round against Brazil, no one believed that China men’s volleyball team could win. However, in the competition, the boys of China men’s volleyball team played to the extreme in attacking and blocking, and finally overthrew Brazil, the world’s No.1 team, 3-0, and won a victory to rebuild their confidence. After that, China men’s volleyball team was influenced by many factors, failed to continue its stable performance, and finally handed over the report card of 12 games, 3 wins and 9 losses.
After a short break, China men’s volleyball team entered the Asian Cup non-stop. Beat China Taipei Team and Bahrain Team with two scores of 3-1, swept Pakistan Team, defeated Iran Team, and defeated South Korea Team in five games-China Men’s Volleyball Team reached the final and ushered in the ultimate contest with Japanese Team. With Zhang Jingyin’s excellent performance and the team’s good performance in blocking and serving, China men’s volleyball team finally won the championship with a 3-0 victory.
In the Asian Cup competition, China Men’s Volleyball Team actively adjusted and finally won many times when the score was behind, which improved the team morale and ushered in a highlight moment. However, at the World Men’s Volleyball Championships that followed, in the confrontation with the top teams in the world, China Men’s Volleyball Team did not win a game, and was at the bottom of the group, seeing the gap between itself and its opponents.
Through the tempering of this year’s World Series, the combat effectiveness and cohesion of China Men’s Volleyball Team have been further improved, and the outside world has also seen the role of senior national players such as Zhang Jingyin, Dai Qingyao, Yu Yaochen and Peng Shikun, as well as the growth of young players such as Yang Yiming. At the same time, the team also exposed shortcomings and shortcomings, and head coach Wu Sheng and the players attached great importance to this. Wu Sheng said that the gap between China men’s volleyball team and the world’s high-level teams is still very large, "not only technically, but also in physical fitness, physical fitness and understanding of volleyball."
In the coming year, China Men’s Volleyball Team also has a heavy international competition task, the most crucial of which is the Paris Olympic qualifiers. What kind of performance the boys will show is worth looking forward to.
League launched reform measures
At present, the 2022-2023 China Volleyball Super League is in full swing, with 28 teams participating in the men’s and women’s volleyball leagues.
At the beginning of this year, the National Volleyball Work Conference was held. Under the active promotion of the State Sports General Administration, the volleyball league started the reform work. This season’s Super League has ushered in new breakthroughs and changes, and launched a series of new measures, including the launch of the league slogan of "bravely surpassing, fighting first", further building the brand marketing system, improving the brand system and enhancing brand value, and the league competition system is developing in a more standardized direction.
The foreign aid policy is one of the most remarkable changes in the league. This season, there is no limit to the number, position and number of foreign aid players in the Super League, which makes the number of foreign aid imports hit a new high in recent seasons, including many top-level athletes in the world. Judging from the course of the competition, this move has really further improved the antagonism and competitive level of the competition. Many young players have also gained more opportunities to learn and exercise with the help of high-level foreign aid.
It is also undeniable that the problems of low commercialization level and poor management and operation mechanism of the Super League still exist. Volleyball, as one of the three big balls, has not reached its due position and level in domestic league matches, nor has it shown its unique value.
As the cornerstone of the national team construction, the reform and development of the league still has a long way to go, and it needs to find the right direction and make contributions for a long time.

Typhoon ＂Fireworks＂ made a curtain call in Shanghai. What is the ＂magic capital enchantment＂ that Shanghainese talk about？

　　China news agency, Shanghai, July 28th (Reporter Li Shuzheng) "Shanghai has ‘ Magic Capital Enchantment ’ Typhoon can’t ‘ Break the defense ’ 。” Whenever a typhoon strikes, the first reaction of Shanghai netizens is often like this.

　　On the 28th, the Shanghai Central Meteorological Observatory announced that the impact of Typhoon Fireworks on Shanghai was basically over. In the face of the "fireworks" which ranked first in rainfall and second in maximum wind speed in the process of typhoon influence in recent ten years, Shanghai passed safely without major accidents and accidents, and the city was running smoothly.

　　What exactly is the "magic capital enchantment" that Shanghai people talk about?

　　"Enchantment" originally refers to an area protected by some supernatural power, forming a barrier separated from the outside world. In 2012, the "Magic Capital Enchantment" first appeared in Shanghai media reports on typhoons, meaning that the operation of this mega-city was not invaded by typhoons.

　　Shanghai is an insulator of typhoon? Looking back at meteorological data, this is not the case. In the "Magic has a typhoon ‘ Enchantment ’ " This statement appeared in the past ten years, which is precisely the decade when Shanghai suffered the worst typhoon since 1949.

　　According to the data of Tropical Cyclone Data Center of China Meteorological Bureau, there have been nine typhoons landing in Shanghai since 1949, including four in this decade.

　　Whether it’s Typhoon Phoenix, which landed in Shanghai in 2014, Typhoon Abe, Lark and Wambia, which landed once a week in 2018, or Typhoon Fireworks & HELIP; … The pressure of flood control and typhoon prevention in Shanghai is not small.

　　"What is there in Shanghai ‘ Magic Capital Enchantment ’ It’s just that someone is guarding. " On the social platform, there is also another kind of "unbelieving" voice.

　　Before the typhoon "fireworks" came, a video of "tying the plane" became popular on the Internet. Affected by the typhoon, all flights in and out of Shanghai Pudong and Hongqiao airports were cancelled on the 25th. China Eastern Airlines tethered the aircraft to ensure that the aircraft would not move when the typhoon struck.

　　"Why is there a kayak in the subway station?" On the 24th, some people found this "fresh object" in Zhongshan Park Station of Metro Line 2, and they were curious to ask. In fact, in response to the "Typhoon" fireworks, more than 50,000 policemen in Shanghai are waiting for their death. Canoeing in the subway station is one of the relief materials prepared in the previous flood control and typhoon prevention drills.

　　According to the characteristics of the police situation in the flood season in previous years and the actual situation in the jurisdiction, the Shanghai fire department improved the emergency plan for 608 underpasses, 13 river-crossing tunnels and 457 sections prone to water accumulation in Shanghai. There are 37 pre-garrison points in some areas. Before the "fireworks" came, 121 flood control vehicles, 86 boats, 465 pumps and more than 6,000 sets of water rescue and life-saving equipment were ready.

　　By 12: 00 on the 25th, before the first landing of Fireworks, Shanghai had transferred more than 360,000 people, including construction workers working outside the first-line seawall, residents living in dilapidated houses and shed houses in the field, construction workers working in temporary houses on the construction site, and boat people entering Hong Kong to take shelter from the wind.

　　"Would rather ‘ Ten against nine empty ’ " It is a vivid embodiment of Shanghai’s concept of putting people’s lives and property first.

　　"There are 54 sections of roads with accumulated water, 15 residential areas with accumulated water, and 13 underpasses with accumulated water. At present, except for 2 roads and 7 underpasses, the remaining accumulated water has been eliminated … …” During the typhoon "Fireworks" affecting Shanghai, the "Flood Control and Typhoon Prevention Map" formed by the "One Network Unified Management" flood control and typhoon prevention command system has been updated in real time.

　　Relying on the construction of "unified management through one network", the "urban brain" function of Shanghai’s urban transportation centers at the two levels has gradually emerged, and the early warning and judgment have become more accurate.

　　Pudong New Area Urban Operation Center said that the application scenario of flood control and typhoon prevention has realized the automation of the response to the plan. Under the command of version 3.0 of "Urban Brain", the flood control and typhoon prevention have realized rapid response and scientific scheduling.

　　According to the statistics of Pudong New Area Urban Transportation Platform, as of 0: 00 on the 26th, during the period of typhoon "fireworks", the platform has accepted 1,152 requests from citizens for flood control and typhoon prevention.

　　When Shanghainese talk about "Magic Capital Enchantment", what are they talking about? Perhaps it is not some supernatural force, but everyone’s "Shanghai". (End)
