Cell Phone thermal cooling

      While smart phones allow users to experience high performance, most users have experienced the hot back shell of mobile phones. Especially when playing games or working for a long time, the phenomenon of mobile phone heating brings great potential safety hazards to users, so it is necessary to solve the problem of heat dissipation of mobile phones, Mobile phone manufacturers are looking for various materials or advanced heat dissipation methods to "cool" the mobile phone and improve the use experience.

     Although many mobile phones now have relevant heat dissipation technologies, they still can not completely change the situation of mobile phone heating. Although the heat dissipation problem can not be completely cured, we can try our best to control the mobile phone from being too hot during the use of mobile phones, so we need to understand the causes of heating.

The reason that cell phone heats:

      The root cause of mobile phone heating is that during the operation of the mobile phone, the current output by the battery generates heat when passing through the electrical components. Under normal circumstances, the mobile phone will certainly generate heat during the operation. The main places of smart phone heating include CPU, chip, processor, mobile phone battery, etc

Thermal solutions:

Graphite sheet heat dissipation:

      This is the mainstream way of heat dissipation at present. Graphite heat dissipation  is a way to evenly distribute the central temperature of mobile phone heating on a two-dimensional plane, so as to facilitate uniform heat dissipation. In addition, the heat on the surface of the processor is directly transferred to the heat dissipation material, so as to ensure the normal and stable operation of components in the mobile phone.

Metal back plate heat dissipation:

      In this way, a layer of metal heat conduction plate is placed inside the mobile phone to transfer the heat generated by the mobile phone to the metal heat conduction plate and then to the four parts of the body, so as to ensure that the mobile phone can operate at normal temperature and allow the heat to diffuse rapidly.

Heatpipe Applications:

     Heat pipe is an artificial component with excellent heat transfer. The commonly used heat pipe is composed of three parts: the main body is a closed metal pipe, there is a small amount of working medium and capillary structure inside, and the air and other sundries in the pipe must be excluded.

     The advantages of this heat dissipation method are that the heat pipe self cooling heat dissipation system does not need a fan, has no noise, is maintenance free, is safe and reliable, and the air cooling or even self cooling of the heat pipe can replace the liquid cooling system, saving water resources and related auxiliary equipment investment. In addition, the heat pipe heat dissipation can concentrate or even seal the heating parts, and move the heat dissipation part to the outside or far away, which can prevent dust, moisture and explosion, Improve the safety, reliability and application scope of electrical equipment.

     Therefore, the heat dissipation of mobile phones has always been a major problem perplexing the development of mobile phones. I believe that with the development of science and technology, this problem will be effectively improved.
