Problems solved by technology

The heat of the CPU is finally transferred to the screen and the back cover through heat conduction, and the screen and the back cover exchange heat with the environment through radiation and natural convection. Due to the limitation of the heat dissipation surface area of ​​the mobile terminal, in the case of satisfying the user experience, determine the size of the mobile terminal There is a design bottleneck of the theoretical maximum heat dissipation
The heat consumption in some application scenarios of mobile terminals with determined external dimensions is greater than the theoretical maximum heat dissipation of the device, especially in scenarios where the heat consumption of the device is concentrated locally, which will lead to the heat dissipation risk of the surface temperature exceeding the standard

Abstract

The invention provides a mobile terminal, which comprises a display screen and a shell, wherein the display screen is assembled to the shell; the shell comprises a body and a baffle; the surface of the body is provided with at least one through hole; and the baffle is movably connected with the body and covers the through hole. When the mobile terminal carries out heat dissipation, the baffle is controlled to move to expose the through hole, and therefore, heat generated by components and parts in the mobile terminal circulates with external air. The invention also provides a heat dissipationmethod. Through the mobile terminal and the heat dissipation method provided by the invention, on the basis of guaranteeing heat dissipation requirements, an amount of dust which enters the mobile terminal is reduced, and the service life of the mobile terminal is prolonged.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a mobile terminal and a heat dissipation method. Background technique [0002] At present, mobile terminals on the market adopt the design concept of natural heat dissipation system, which transfers the heat inside the mobile terminal to the screen and back cover through radiation and heat conduction, and exchanges heat with the environment through the screen and back cover, thereby controlling the surface temperature of the mobile terminal. Mobile terminals designed with a natural convection cooling system include: screen, middle frame, single board, CPU, battery, and rear cover. The heat of the CPU is finally transferred to the screen and the back cover through heat conduction, and the screen and the back cover exchange heat with the environment through radiation and natural convection. Due to the limitation of the heat dissipation surface area of ​​the mob...
