Problems solved by technology

The heat dissipation effect of thermoelectric cooling is good, but in the current technical solution, precise temperature control is not achieved, and condensation is likely to occur in the contact area between the cold end of the thermoelectric module and the mobile phone, while the cooling effect of the fan is poor, and the noise is large, which affects the user's use Experience when playing games or watching videos on mobile phones
That is, the existing external heat dissipation has the following problems: when the mobile phone uses thermoelectric cooling for heat dissipation, it is easy to generate condensation; the fan assembly for heat dissipation at the hot end of the thermoelectric cooling module has the problems of large noise and large volume

Abstract

The control method and heat dissipation device for the heat dissipation device of the mobile device of the present invention, the present invention detects the temperature and environmental humidity of the backplane of the mobile device through the detection module, calculates the dew point temperature td according to the temperature and the environmental humidity through the control module, according to The control module controls the temperature of the cold end of the semiconductor refrigeration sheet of the heat dissipation device, thereby preventing condensation. The present invention preferably adopts metal foam as heat dissipation material, replaces common heat dissipation fan, realizes zero noise, and makes heat dissipation device more compact and miniaturized.

Description

technical field [0001] The present invention relates to a heat dissipation device for a mobile device and a control method thereof, in particular to a heat dissipation device for a mobile phone and a control method thereof. Background technique [0002] In the era of smart phones, as the main frequency is getting higher and higher, the power consumption is getting higher and higher, and the heat generation is getting higher and higher. Especially when the phone is charging and playing heavy games or watching high-definition video, the heat generated by the phone reaches the maximum. When the mobile phone generates the most heat, it is easy to crash or burn the hardware due to the excessive heat generation of the mobile phone, thereby reducing the service life of the mobile phone; When the phone is hot, it will reduce the experience of people using the mobile phone. [0003] There are two types of heat dissipation solutions for mobile phones: internal heat dissipation and e...
