Nowadays, the performance of electronic devices in our hands is constantly improving, and the performance of many mobile phone processors has caught up with some computer processors. But at the same time, the defect brought by the improvement of performance is that the equipment heating is serious, which greatly affects the user’s actual use experience. Recently, Huibao has published a list of the “hot” index of game phones. We can see that Xiaomi 10 Pro is not only listed as a game phone, but also better than the game phones on the market in terms of temperature control. < / P > < p > “born for a fever” is the most classic slogan of Xiaomi, which means that the configuration is enough for fever, and the price is enough for fever. However, many netizens ridiculed that in addition to the price and configuration, the temperature of the mobile phone is also very “feverish”, which also indicates that Xiaomi’s products in the early stage of temperature control are relatively poor, so how does Xiaomi “reduce the fever” step by step from a “warm hand treasure”? < / P > < p > first of all, we need to understand several main heat sources of mobile phones. First of all, it is the CPU of mobile phones. With the increasing performance of CPU nowadays, its power consumption will be more and more large. In terms of device principle, CPU is mainly composed of transistors. When working, the transistor needs to be continuously powered on and powered off. The higher the performance is, the higher the frequency of power on and power off will be, and the heat output of the transistor will naturally go up. < / P > < p > because the current technology is unable to reduce the resistance in the circuit to 0 Ω, according to Ohm’s law, as long as there is resistance in a circuit, there will be heating phenomenon, and the increase of power consumption will naturally make the current and voltage in the circuit rise, and the temperature will be higher and higher. So if you want a higher performance CPU, its heat will certainly increase, which is an embarrassing situation that we can’t avoid at present. < / P > < p > the second part is the battery part. When users use the mobile phone, a part of the chemical energy inside the mobile phone battery will be converted into electrical energy to provide electricity for the mobile phone, while other chemical energy will be converted into heat energy and some other energy. In addition, the ohmic Law mentioned above will also bring some heat. Therefore, if the power consumption of the mobile phone is too high in a short period of time, the heating capacity of the battery will rise sharply. < / P > < p > if the material of the battery is not good, the electrolyte will evaporate too fast when the user charges the mobile phone. If the electrolyte is too small, the lithium ion inside the battery will form sulfuric acid crystal or some small floating blocks. If it is stuck on the lead plate inside the battery, the resistance of the battery will be further increased, so that the calorific value will be higher. < / P > < p > the screen of mobile phone is also one of the important reasons for the popularity of mobile phone. Nowadays, LCD panel and OLED panel are basically used in the mobile phone screen on the market. The main light source of the former comes from a luminous backplane, while the latter is that the pixels in the whole screen will emit light. Both of them will produce different degrees of heat in the working process. If the screen temperature is too high, the screen burning may occur for a long time. < / P > < p > if the internal temperature of the mobile phone is too high, the CPU frequency will be reduced, and some pictures will drop frames, get stuck or even crash and restart. So in today’s increasingly high heat of mobile phones, the cooling of mobile phones has become a standard for many users to measure whether they can be called flagship. < / P > < p > the heating of these components mentioned above is inevitable. What mobile phone manufacturers can do is to do a good job of heat dissipation, so that users’ palms do not have to suffer from “baking”. For this reason, mobile phone manufacturers are constantly looking for heat dissipation solutions and better thermal conductive materials to solve the problem of “fever” of mobile phones.
currently mobile phone cooling materials mainly include graphite heat dissipation film, thermal conductive gel and copper tube /VC hot plate. The first application of graphite heat dissipation film was the iPhone 4, which was famous in those years. Apple covered a whole layer of graphite heat dissipation film on its back panel. When the mobile phone is hot, most of the heat can be quickly transferred to the back and frame of the phone through the graphite heat dissipation film. At that time, the A4 processor was able to play all the powerful performance of Android. < / P > < p > later, graphite cooling film became popular in mobile phones. Basically, all mobile phone manufacturers will stick a layer of graphite heat dissipation film on the inside of the back cover of the fuselage. With the characteristics of low cost, good heat dissipation performance and small thickness, it is still the first choice for mobile phone manufacturers to solve the cooling problem of mobile phones. < p > < p > and Xiaomi 10 Pro not only uses graphite heat dissipation film, but also uses metal material for the frame part of millet 10 pro, which can transfer heat faster and more effectively, and the heat dissipation effect will be better.
is targeting the motherboard and CPU parts with the most serious heating capacity. Mobile phone manufacturers use silicone grease and heat conducting gel. Silicone grease and thermal conductive gel can reduce the thermal resistance of CPU and its upper cover plate, and speed up the transmission of heat upward. When the heat is transferred to the graphite heat dissipation film, it will spread to the outside of the fuselage through the frame of the mobile phone, thus reducing the overall temperature of the fuselage. < / P > < p > these alone can not suppress the high heat inside the mobile phone, so mobile phone manufacturers innovatively add copper tube design to the interior of mobile phone. Sony Z3, which is equipped with “Firedragon 801”, adopts an exaggerated double copper tube design. Its working principle is: some liquid is built into the copper tube, which will evaporate into gas when it feels the heat emitted from the inside of the mobile phone, and the gas will liquefy into liquid when it contacts the copper tube wall. The rapid circulation of the two can take away a lot of heat. This time, Xiaomi 10 Pro is equipped with VC soaking plate, which is the upgraded and optimized version of copper tube heat dissipation technology, and the area of this VC soaking plate of Xiaomi 10 Pro reaches 3000 square mm, which is more than three times that of ordinary 5g mobile phone. Lu Weibing, President of redmi, once said when popularizing the technology, “if the previous copper tube heat dissipation technology is carried out through a bamboo, then the VC soaking plate is a bamboo raft, which can better take away the heat from all directions.” < / P > < p > in addition to the CPU, battery and screen mentioned above, the camera module is also a hot user, although few users use the camera for a long time in daily use. However, this situation can not be ruled out. For this reason, Xiaomi 10 Pro pastes copper foil on the back of the camera module, and adds a double-layer graphite film in the corresponding position of the middle frame for the camera heat dissipation. There are also special heat dissipation films in the flash parts ignored by many manufacturers and users. < / P > < p > in addition, the Xiaomi 10 Pro also has a built-in matrix temperature sensor and a number of temperature sensors inside the fuselage, which can real-time monitor the temperature of CPU, camera, battery, motherboard and other different areas, and reasonably allocate the temperature control scheme of the whole machine. So as to reduce the frequency reduction due to the high temperature of the fuselage. < / P > < p > the perfect heat dissipation system enables the heat generated by the CPU to be transferred to the outside of the body through its heat dissipation system when playing games, so that the millet 10 Pro can still maintain a relatively normal temperature after a long time of games, neither hot hands nor the performance of the mobile phone will be reduced due to the high internal temperature. < / P > < p > there was an authoritative person’s popular science before: the power consumption of 5g chip will be 2.5 times of that of 4G chip, and the calorific value will be doubled. If mobile phone manufacturers continue to use 4G era cooling solutions on 5g mobile phones, 5g mobile phones will only be too hot to accept. While Xiaomi 10 pro’s super conscience cooling module does not reduce the temperature of the mobile phone to a comfortable temperature, it still has a lot of advantages compared with other models. < / P > < p > about next Tuesday, Xiaomi 10 supreme commemorative edition will meet with rice noodles. According to the information disclosed so far, compared with Xiaomi 10 pro, the commemorative version of Xiaomi 10 has a great improvement in performance, camera, charging and screen. This also shows in disguise that the heat dissipation of the supreme commemorative version of Xiaomi 10 will be better than that of Xiaomi 10 pro. As the representative work of Xiaomi’s 10th anniversary, Xiaomi will certainly not let such a significant product overturn on the most basic experience. Huawei has finally made a choice! Xiaomi and ov have also followed up. Have you ever thought about today?
