Many people find it particularly hot when playing with mobile phones. This is because the CPU and various electronic components are running during the use of the mobile phone, which will generate heat. Let's summarize the cooling methods of mobile phones for everyone.
Cell phone cooling method 1 1, ice cooling method
It is the best way to solve the problem of temporary fever of mobile phone by putting ice cubes in a sealed bag and putting them behind it. However, this method treats the symptoms rather than the root cause. Don't use the mobile phone except when it is seriously hot. The mobile phone is at risk of water ingress.
2. Static method
Playing mobile phones with 4g, especially games and videos, will be very hot. The only way is to leave the phone standing. If it is left standing, it is best to put it on a table, wall and other places with low temperature, which will help the phone cool down.
3. Turn on the flight mode
This method is suitable for people who have just finished playing games and their mobile phones are hot. You can try switching your phone to airplane mode. After the airplane mode is turned on, the mobile phone will automatically turn off any software related to wifi, thus reducing the power consumption of the mobile phone and allowing the mobile phone to dissipate heat faster.
4. Buy a mobile phone radiator
You can go to Electronic City, JD.COM, Taobao and other stores to buy a mobile phone radiator and put it on your mobile phone. It will be more comfortable when you play games, and the mobile phone will dissipate heat faster.
5. Don't play with your mobile phone while charging.
Playing mobile phone while charging is very harmful to the behavior of mobile phone, and it is also the main reason why mobile phone is getting hotter and hotter. When the battery consumes current, it inputs current. Repeated circulation will affect the life of the mobile phone, thus deepening the fever of the mobile phone. Try to turn it off when charging, which not only reduces the charging time, but also protects the battery.
Mobile phone cooling method 2 The key to better cooling effect of mobile phone is the mobile phone case, so there are several options:
Heat dissipation metal shell (that is, the metal material with dense holes)
simple/fine/pure metal
Plastic hard shell
The principle of heat dissipation is simple. The above materials have faster heat transfer, wider heat dissipation area and naturally higher heat dissipation speed. Compared with plastic, metal has much stronger thermal conductivity, which is beneficial to heat dissipation. If the metal surface is treated with some surface treatments, such as baking paint, the heat dissipation will be better.
In addition, the slowest heat dissipation is the silicone phone case. Silicone, soft plastic mobile phone case, not to mention slow heat transfer, will not dissipate heat at all, only gather heat, so that your mobile phone will only get hotter and hotter. If you want to dissipate heat well, it is the best state to dissipate heat without a mobile phone case.
The cooling mode/scheme of mobile phone determines the cooling material it uses. Common methods are:
1, copper tube (liquid-cooled) dissipates heat and conducts heat by circulating phase change. The copper tube is used to conduct heat from the core heating area to the whole back cover area, and the heat dissipation surface is increased;
2. The silica gel graphite sheet dissipates heat, that is, the heat in the core heating area is transferred to the whole back cover area through silica gel and graphite sheet, and the heat dissipation surface is increased; The ordinary silicon graphite sheet made of Wang Li's new material can be used inside the mobile phone, as well as outside the mobile phone case. For example, the radiator sticker of the IPHONE's mobile phone case uses the silica gel graphite sheet of Wang Li's new material.
3. Increase air flow to dissipate heat, mainly using internal and external cooling fans to dissipate heat. At present, mobile phones basically do not use cooling fans, mostly in the form of external cooling fans;
The new material of Wang Li's new material can be selected for the design of mobile phone heat dissipation scheme and related thermal management scheme. After all, we focus on the design of digital electronic heat dissipation scheme and the manufacture of heat dissipation materials, and can provide suitable heat dissipation schemes and professional heat dissipation materials for mobile phones.
Of course, it is simpler to connect a radiator directly.
According to the introduction, first of all, you can limit the number of mobile phone background programs: one of the reasons why mobile phones are hot is that there are too many background programs, and some programs even start automatically, which consumes your memory and traffic inexplicably. You can't be soft on this App. Select "background process restriction" in mobile phone settings, and select the restricted number as needed.
Don't use your mobile phone for a long time: If you use your mobile phone for a long time, it will continue to heat up and you can't stop to cool down. The longer the time, the higher the temperature. The ideal working environment temperature of mobile phone is 0℃~ 35℃. In this temperature range, the activity of lithium battery remains relatively stable. Avoid placing the phone at a temperature higher than 35°C, otherwise the battery capacity may be permanently damaged.
It is also related to mobile phone accessories: there are many kinds of mobile phone cases on the market, and some mobile phone cases have poor heat dissipation, which will not only affect the heat dissipation of mobile phones, but also aggravate the fever of mobile phones. In summer, which is not conducive to the cooling of mobile phones, try not to wear a mobile phone case, or choose a mobile phone case with better cooling.
abstract
Thermal power consumption design runs through the whole mobile phone industry chain, and the experience users get is only the result of layer-by-layer accumulation. The performance of mobile phones is getting higher and higher, and fever is always inevitable without a big step in technology. However, due to various commercial factors, most mobile phone manufacturers can actually do little in the design of mobile phone thermal power consumption, and even directly conflict with the experience of performance and slimness, which further tests the advantages and disadvantages of mobile phone manufacturers in weighing many factors and the application of new technologies.
Heat dissipation method of mobile phone 4 1, internal heat dissipation
At present, most smart phones adopt graphite heat dissipation scheme, and the basic principle is the same, but manufacturers will make some adjustments to their product design. First, let's look at something like graphite. Graphite is an allotrope of elemental carbon, which is stable, so it is very common in many industrial applications.
At present, we know that graphite has high temperature resistance, electrical and thermal conductivity, lubricity, chemical stability, plasticity and thermal shock resistance. As a part of mobile phone design, we can see many uses of graphite. For example, graphite heat sinks currently used in mobile phones make use of the thermal conductivity of graphite.
2. The external heat dissipation method of the mobile phone is as follows:
The mobile phone case is made of n kinds of materials, which is the first choice for better heat dissipation.
(1) heat dissipation metal shell.
(2) Metal+plastic heat dissipation.
(3) There are three kinds of plastic hard shells, and the heat dissipation principle is very simple. The above materials have faster heat transfer, wider heat dissipation area and naturally higher heat dissipation speed.
Extended data:
Other cooling technologies of smart phones;
1, ice nest cooling scheme
Ice nest heat dissipation was put forward when OPPOR5 was released. On the basis of the basic graphite cooling scheme, an exclusive patented ice nest cooling system is adopted. In this system, liquid metal material, usually solid, is added between the chip and graphite. When the chip heats up, the absorbed heat becomes liquid, which improves the heat transfer efficiency.
2. Micro heat pipe scheme
NEC company proposed a miniature heat pipe. The cooling scheme adopts flat heat pipe, which has heat dissipation ability, reduces the heat flux density of the cooling surface and reduces the thermal resistance of the chip cooling path. This scheme comes from the heat dissipation technology of computers and notebook computers. For mobile phones, heat pipes need to be miniaturized. The miniaturized heat pipe can be used for cooling smart phones.
