How does the built in heat dissipation of gaming phones do it?

In 2019, the RedMagic III pioneered a high-efficiency centrifugal fan, composed of a multi-dimensional three-dimensional cooling system and a 90 Hz high refresh rate screen, once again defining the limits of gaming phones. In Master Lu's new machine performance ranking in April, he mastered the first place with a score of 452,948 points, and at the same time topped the list with an average running score of 380,921 points in the Antutu performance ranking in May, and won the double championship in the two performance rankings.

The Red Devil adopts the flagship configuration of 2019, supplemented by a number of evolutionary equipment technologies, plus the industry's first night cooling and air-cooled heat dissipation system, which not only has a combination of high-performance heat dissipation materials and heat pipes, but also puts a centrifugal fan in the limited fuselage, which brings cold air from the outside into the machine and blows the internal heat out of the body, which can control the speed in the game space, and is also the only endoplasmic fan cooling system in the industry so far.

It is worth mentioning that as early as the MWC exhibition in 2018, Nubia had already shown a prototype with a unique architecture with a physical fan for heat dissipation. In order to make the iris three in the operation of high load, will not be reduced due to heating, sealing is the most direct solution. Although turbofans are normal in gaming laptops, it is not easy to do in highly integrated smartphones, which need to be explored in many aspects such as noise, efficiency, life, and power consumption, and it is also necessary to plan reasonable air ducts to test the design skills of manufacturers.

According to official data, the centrifugal fan has a speed of 14,000 revolutions and can run continuously for 30,000 hours per minute.

In the 30-minute test of the default mode of peaceful operation, we adjusted the fan speed of the centrifugal fan to the fastest half an hour, the highest temperature on the back is Celsius, the highest temperature on the front is Celsius, the highest on the back is Celsius after an hour, and the highest on the front is Celsius, usually when we play games, the contact area between the hand and the back of the machine is the largest, so the temperature on the back is more likely to affect the experience of the game, then the Red Magic Three can do about 37 degrees Celsius, and the effect of fan heat dissipation is really good.

The mobile phone generally conducts heat to transfer the heat in the mobile phone to the mobile phone screen and back shell to disperse the heat and dissipate the heat. Nowadays, some gaming phones, which are specially designed for gaming, also use fans to dissipate heat.

There is a small fan built into the gaming phone that keeps rotating to dissipate heat, and there is liquid water cooling for heat dissipation, that is, there is a circulating water system inside, and the water flow takes away the heat.

There will be a small built-in fan inside, which will drive the wind to dissipate heat from the phone through the rotation of the fan. Some also make use of the water cycle to cool down the phone.

1.Turn off unnecessary apps: When using your phone, close apps you don't need to use as much as possible, which can reduce the burden on your phone and reduce the heat of your phone.

2.Turn off background apps: Many apps run in the background, which can cause your phone to get very hot. Closing these apps can reduce the burden on your phone, which in turn reduces the heating of your phone.

3.Reduce screen brightness: The higher the screen brightness, the more the phone heats up. Turning down the screen brightness can reduce the heat of your phone.

4.Turn off Bluetooth and Wi-Fi: When Bluetooth and Wi-Fi are not needed, turning them off can reduce the burden on your phone, which in turn reduces your phone's heating.

5.Turn off location services: When you don't need to use location services, turning them off can reduce the burden on your phone, which can reduce your phone's heating.

6.Don't let the phone be charged for a long time: A phone that is charged for a long time is prone to heating, so it should be avoided as much as possible.

7.Reduce the image quality of the game: The higher the image quality of the game, the more serious the heating of the phone. Turning down the graphics quality of the game can reduce the heat on your phone.

8.Avoid using your phone in high temperatures: Using your phone in a hot environment can exacerbate the heat of your phone and should be avoided as much as possible.

9.Don't put your phone in a closed place: Leaving your phone in an enclosed place can cause poor heat dissipation of your phone, which can exacerbate the heat of your phone.

10.Clean up your phone's junk files regularly: Cleaning up your phone's junk files can reduce the burden on your phone, thereby reducing your phone's heating.

What should I do if my phone is too hot to play games in summer? 4 tricks to teach you to solve the hot mobile phone, and finally Zhengqing is a trick.

For friends who love to play games, in the summer of thirty or forty degrees, it is really not easy to play games with a mobile phone, the higher the temperature, the hotter the mobile phone, like a hand warmer in your hand, today I will teach you a few ways to lift Zheng Qian, and easily cool down the mobile phone.

The first trick is to turn on the power-saving mode and close the background apps that you don't need to use, so as to reduce the power consumption of the mobile phone and reduce the heating. When playing games, switch to the balanced mode, reduce the game image quality, reduce the negative cluster load of the processor, and greatly reduce the heat of the mobile phone.

The main reason why the mobile phone is hot is that the CPU is running, especially when playing games, the CPU is running at high speed, and the mobile phone will be hot, because the mobile phone is a confined space and there is no cooling fan, so it will be hot.

The second trick is to avoid using it at high temperatures. If you want to reduce the heat, try to avoid playing with the phone while charging, because the phone itself will heat up when charging, and the second is to reduce the use of the machine outdoors, because the outdoor temperature is high, and the direct sunlight will also cause the temperature to be too high, and the heat dissipation effect of the phone itself is not good, so avoid using it in high temperature scenarios, and the phone will not be hot.

The third trick is to equip the phone with a heat dissipation clip, which can double the heat dissipation of the mobile phone, even if it is outdoors, you can open it to your heart's content. If you wear a mobile phone case, removing the protective case can also improve the heat dissipation of the mobile phone.

The fourth trick is to change a mobile phone with good heat dissipation, such as this OnePlus Ace Racing Edition with a diamond 8-layer heat dissipation system, a large area of VC liquid cooling heat dissipation, plus diamond thermal conductive materials and multi-layer ultra-high-density graphite heat dissipation, these three top heat dissipation combinations, super heat dissipation capacity, even in an environment of more than 40 degrees, after an hour of gaming, the mobile phone is only hot and not hot.

At present, mobile phone manufacturers generally adopt two solutions to reduce the problem of mobile phone heating: one is hardware heat dissipation, such as graphite heat dissipation, and the other is core optimization heat dissipation.

In terms of hardware heat dissipation, most of the previous methods used to solve the heat dissipation problem by using high thermal conductivity materials in the architecture. Traditional thermally conductive materials are mainly metal materials, such as copper, aluminum, silver, etc. However, metal materials have high density and high coefficient of expansion, and cannot meet the requirements of use in occasions that require high thermal conductivity efficiency (such as silver, copper, aluminum.

The thermal conductivity is 430W, 400W, and 238W respectively, so with the increase of the main frequency of mobile phone chips, mobile phone manufacturers have begun to improve the hardware heat dissipation scheme.

The thermal conductivity of graphite heat dissipation film is 2-4 times that of copper, providing better thermal conductivity while reducing the weight of the device.

Heat-dissipating graphite is stacked with graphene, a two-dimensional carbon material with a thermal conductivity of up to 5300 W m·k, which is higher than that of carbon nanotubes and diamonds. It conducts heat quickly in the horizontal direction and has a thermal effect in the longitudinal direction. So we see that many mobile phone brands are now using stone or mu ink for heat dissipation.

For example, Apple, LG, Xiaomi, etc., all use graphite for heat dissipation.

However, with the upgrading of hardware, simple hardware heat dissipation can not perfectly achieve heat control, so there are many manufacturers on the basis of hardware heat dissipation to add kernel optimization heat dissipation, kernel optimization heat dissipation is similar to power-saving software, but there are certain differences, most manufacturers' core optimization can be realized in the bottom layer to control a variety of different CPU support frequency conversion technology, can be dynamically selected at the upper layer according to the system load to dynamically select the appropriate operating frequency, simply put, it can intelligently control the main frequency, Some manufacturers also equip mobile phones with a core for power control.

In addition, some manufacturers will add an ultra-low-power power-saving mode to the mobile phone by implanting a deep sleep module. In contrast, many power-saving software solutions to heat dissipation problems simply use reducing CPU frequency and I 0 scheduling, and some power-saving software may cause more heat generation or more power consumption.
