Problems solved by technology

Although the heat sink can transfer heat from the mobile phone to the heat sink in a timely manner, most of the protective shells are made of plastic, and plastic is a poor conductor of heat, which cannot dissipate the heat of the heat sink in a timely manner, so the effect of heat dissipation is limited
[0005] The second is mainly air-cooled heat dissipation. In the prior art, the fan is generally installed directly. The wind blown by the fan has a small area, and the heat generated by the fan motor is also dissipated by the fan; this method consumes a lot of power and has a large volume. Generally larger, and the leakage of the fan blades is easy to accumulate dust, and the noise of the fan rotation is also relatively large

Abstract

The invention discloses a mobile phone heat dissipation mechanism and a mobile phone shell, the mobile phone heat dissipation mechanism is used for conducting heat dissipation on a heating element on a mobile phone, the mobile phone heat dissipation mechanism comprises an annular air guide part and a compressor, the annular air guide part is provided with a convection channel, an air outlet hole and an air inlet hole, and the air outlet hole and the air inlet hole are communicated with the convection channel; the convection channel surrounds the annular air guide piece by a circle, and the air outlet holes are formed in the inner periphery of the annular air guide piece. An air inlet of the convection channel is communicated with the compressor, the compressor blows airflow towards the air inlet, and the airflow flows to the air outlet hole through the convection channel and is blown out towards the center of the annular air guide piece through guiding of the air outlet hole. According to the mobile phone heat dissipation structure provided by the embodiment of the invention, air is blown to the annular air guide piece through the arranged compressor, convection is formed in the hollow area formed by the annular air guide piece through the annular convection channel and the air outlet holes, and heat generated by mobile phone components is rapidly taken away.

Description

technical field [0001] The present application generally relates to the technical field of mobile phone accessories, and specifically relates to a mobile phone heat dissipation mechanism and a mobile phone case. Background technique [0002] Smartphones emit more heat during long-term use or when running a large number of programs. With the continuous improvement of mobile phone performance, the heat generation of mobile phones is also increasing. If this part of the heat cannot be dissipated in time, It will cause the mobile phone to respond slowly and reduce the battery life. [0003] Although various manufacturers have continuously improved the heat dissipation design technology on mobile phones, they still have not been able to solve the heat problem well, and the temperature can reach 45°C to 50°C when playing large games. In order to protect the mobile phone, people will use the mobile phone case to protect the mobile phone, and the mobile phone case will make the hea...
