step S810, acquiring the state parameters of the mobile terminal;

and step S820, controlling the baffle to be opened according to the state parameters so as to discharge hot air in the mobile terminal from the through hole.

Through the embodiment, the baffle is adaptively controlled to be opened to different positions by detecting the state parameters of the mobile terminal, and meanwhile, the working parameters of the airflow driving device are determined, so that the power consumption can be saved, and the effect of effectively reducing the temperature can be achieved.

Specifically, in this embodiment, the status parameter is information of an application currently running in the foreground of the mobile terminal. The application information may be a category of the application and/or a name of the application. In other embodiments, the state parameter is temperature information of the mobile terminal at a preset position. In step S810, information of the application currently running in the foreground of the mobile terminal may be acquired through a call function of the system. In other embodiments, a sensor is disposed in the mobile terminal, and the CPU determines the temperature information of the mobile terminal at the preset position by receiving the temperature detection value sent by the sensor.

In step S820, the corresponding relationship between the operating parameter of the airflow driving device and the stop position of the baffle and the state parameter is predetermined, and the step of controlling the baffle to open according to the state parameter so as to discharge the hot air in the mobile terminal from the through hole includes the following steps:

determining the working parameters of the airflow driving device corresponding to the application program information;

and controlling the stop position of the baffle plate according to the working parameters of the airflow driving device to expose the through hole, and controlling the airflow driving device to be matched with the through hole according to the working parameters to discharge hot air in the mobile terminal from the through hole.

Through above-mentioned mobile terminal and heat dissipation method, be provided with at least one through-hole on mobile terminal's casing, accelerate through the through-hole and dispel the heat with the inside heat of mobile terminal and the air contact of external world, simultaneously, be provided with baffle and the through-hole cooperation that can control through the manual or mobile device of user on the casing, make when need not to accelerate the heat dissipation through the through-hole, can utilize the through-hole to cover the through-hole and prevent that a large amount of dusts from getting into mobile terminal inside, reduce mobile terminal because the dust gathers the risk that produces the trouble. When the heat dissipation needs to be accelerated, the control baffle plate moves to different positions to open the through holes with different areas, so that the heat dissipation is carried out adaptively. Through the mode, the quantity of dust entering the interior of the mobile terminal can be reduced on the basis of ensuring the heat dissipation requirement, and the service life of the mobile terminal is prolonged.
