Mobile phone rear shell and mobile phone

Abstract

The invention relates to the technical field of mobile phone devices, and discloses a mobile phone rear shell and a mobile phone. The mobile phone rear shell comprises a heat absorbing layer arrangedtoward the interior of the mobile phone, a heat dissipation layer is arranged on one side of the heat absorbing layer away from the interior of the mobile phone, and radiation particles for transferring the heat transferred from the heat absorbing layer into the heat dissipation layer to the outside in the form of infrared radiation are arranged in the heat dissipation layer. In the mobile phone rear shell, the heat absorbing layer absorbs the heat generated by the mobile phone during use, and the heat is transferred into the heat dissipation layer by the heat absorbing layer, the radiation particles in the heat dissipation layer transfers the heat in the heat dissipation layer to the outside in the form of the infrared radiation so as to reduce the temperature of the heat dissipation layer and to improve the efficiency of the mobile phone rear shell to transfer the heat generated by the mobile phone to the outside, thereby improving the efficiency of heat dissipation of the mobile phone and reducing the temperature of the mobile phone, in this way, the service life of the mobile phone is prolonged, and the mobile phone rear shell has a simple structure, a simple preparation process and a low cost.

Description

technical field [0001] The invention relates to the technical field of mobile phone equipment, in particular to a mobile phone rear case and a mobile phone. Background technique [0002] At present, mobile phones mainly use graphite sheet heat dissipation, heat pipe heat dissipation, heat conduction gel heat dissipation, metal backplane heat dissipation, and ice nest heat dissipation and other heat dissipation methods. These heat dissipation methods mainly improve the process of heat transfer from the inside of the mobile phone to the back cover of the mobile phone. However, the heat dissipation efficiency of the mobile phone is low due to the low efficiency of heat transfer to the outside by the back cover of the mobile phone. Contents of the invention [0003] The invention provides a mobile phone rear case, in which the radiation particles in the heat dissipation layer of the mobile phone rear case transfer the heat in the heat dissipation layer to the outside in the fo...
