For example, step 110 may implement detecting an application scenario of the mobile terminal by acquiring a work progress of the mobile terminal. Step 110 may also be implemented to detect the holding position of the mobile terminal by acquiring the screen direction and the application scene of the mobile terminal. When the mobile terminal is a mobile phone, the application scene of the mobile terminal may be a game scene, a video scene, a web scene, a call scene, a music scene, or the like. Specifically, the screen direction of the mobile terminal may be a landscape screen direction or a portrait screen direction.

And step 120, determining a heating source according to the application scene of the mobile terminal.

Specifically, the application scene of the mobile terminal and the heat source may have a corresponding relationship, and when the application scene is determined, the heat source corresponding to the application scene may be determined according to the corresponding relationship between the application scene of the mobile terminal and the heat source.

For example, step 210 may implement detecting an application scenario of the mobile terminal by acquiring a work process of the mobile terminal. Step 210 may also be implemented by acquiring a screen direction and an application scene of the mobile terminal to detect a holding position of the mobile terminal. When the mobile terminal is a mobile phone, the application scene of the mobile terminal may be a game scene, a video scene, a web page scene, or a call scene. Specifically, the screen direction of the mobile terminal may be a landscape screen direction or a portrait screen direction.

Wherein, the heating source corresponding to the application program type can be more than or equal to one. For example, when the mobile terminal is a mobile phone and the application program type of the mobile terminal is a game, the heat source corresponding to the game includes a CPU, a speaker, and the like.

Specifically, when the number of the heating sources corresponding to the application scenario is greater than one, for example, two heating sources corresponding to the application scenario are provided, and if the two heating sources are a CPU and a speaker, when the temperature of the area where the CPU is located is greater than the preset temperature threshold corresponding to the CPU, step 240 starts the target heat dissipation module corresponding to the CPU; when the temperature of the area where the horn is located is greater than the preset temperature threshold corresponding to the horn, step 240 starts the target heat dissipation module corresponding to the horn.
