Embodiment 1

[0052] like figure 1 As shown, the embodiment of the present invention provides an adaptive cooling method for a mobile terminal, which specifically includes:

[0053] Step S101: Obtain the real-time temperature of each heat source distributed in different positions of the mobile terminal.

[0054] Among them, a plurality of functional circuits are distributed in the mobile terminal, and a functional circuit may be composed of one or more hardware circuits, and during the operation of the mobile terminal, each hardware circuit will generate heat due to different degrees of thermal effects, and each As different heat sources of mobile terminals, hardware circuits have different locations and functions, and are affected by thermal effects differently. Therefore, the real-time temperatures are different, and the corresponding sensitive temperatures are also different. Specifically, the real-time temperature of each heat source distributed in different positions of the mobile ter...

Embodiment 2

[0063] The first embodiment above briefly introduces the adaptive cooling method of the present invention, which will be further explained in conjunction with specific application scenarios and examples below.

[0064] Specifically, after the main heat source and the cause of heat are determined, different cooling strategies are determined according to different heat sources and their causes, and the main heat source is cooled. The following will give an example description combining several common heat source overheating and common application scenarios.

example 1

[0065] Example 1: When the real-time temperature of the power amplifier circuit of the mobile terminal exceeds the first preset threshold due to voice services, the power amplifier is controlled to turn on or off the uplink switch, or turn on or off the downlink switch according to the current call state.

[0066] When the thermal sensor detects that the real-time temperature of the power amplifier circuit exceeds the high temperature threshold corresponding to the power amplifier circuit, it is determined that the power amplifier circuit is a main heat source, and then the current application scenario or application process in the business is detected by means of baseband chip or application process acquisition. Utilization rate, for example, if it is detected that the process usage rate of the voice service is the highest, then it is determined that the current call scene is divided into calling and called states, and the power amplifier can be controlled according to the use ...

Description

technical field [0001] The invention relates to the field of intelligent mobile terminals, in particular to an adaptive cooling method and device for a mobile terminal. Background technique [0002] Nowadays, as the functions of mobile terminals become more and more abundant, taking mobile phones as an example, the display screens are getting bigger and bigger, the brightness and pixels are getting higher and higher, the battery capacity is getting bigger and bigger, and the number of cores of CPU processors and GPS processors And the main frequency is getting higher and higher. Due to the heating of the mobile terminal, it will affect its transmission and reception performance, deteriorate the communication quality, and reduce the data upload and download throughput. In addition, since the current mobile phone batteries are all lithium batteries composed of chemical liquids, excessive heating temperature will cause violent chemical reactions in the lithium battery, resulti...
