Mobile terminal

Abstract

A heat-dissipating mobile terminal includes a main body, a heat dissipating member positioned in the main body, and a back cover detachably connected to the main body. The main body includes a heat-producing element and the heat dissipating member includes a heat radiator arranged above the heat-producing element. The back cover defines a perforated portion above the heat dissipating member. The heat radiator is integrated with the main body. The heat radiator is exposed to external cooler air by the perforated portion in the back cover. The mobile terminal of the present disclosure effectively improves heat radiating efficiency and reduces cost.

[0002] Nowadays, mobile terminals (such as mobile phones, tablet computers, etc.) have more and more functions, and the power consumption is also increasing. It is inevitable that a lot of heat will be generated inside the mobile terminal. If the heat is not evacuated in time, the high temperature will damage the The electronic components inside the mobile terminal will reduce the service life of the mobile terminal, or even be directly damaged

[0003] In order to prevent the internal temperature of the mobile terminal from being too high, a prior art is to set a metal cover on the heating element, and attach a high thermal conductivity material to the outside of the metal cover, so that the heat generated by the heating element is conducted to the high thermal conductivity material through the metal cover. However, the high thermal conductivity material is not in direct contact with the external cold air, and the heat it carries still needs to be exchanged with the external cold air through the back cover of the mobile terminal, so the heat dissipation efficiency is not high, and the high thermal conductivity material is generally graphite sheet, Copper foil, etc., its cost is relatively high

[0004] Another existing technology is to dissipate heat by setting diversion holes, that is, guide the external cold air to the surface of the heating element for heat exchange through diversion settings. This method of heat dissipation does not require heat-conducting materials and has low cost. Insufficient heat dissipation area of ​​components leads to low heat dissipation efficiency, and this method will bring dust, fluid or water vapor into the product, seriously affecting the safety of the product
