HEAT-CONDUCTING MEMBER AND ELECTRONIC DEVICE

Title:

HEAT-CONDUCTING MEMBER AND ELECTRONIC DEVICE

Document Type and Number:

WIPO Patent Application WO/2020/238865

Kind Code:

A1

Abstract:

Provided are a heat-conducting member and an electronic device. The heat-conducting member comprises: a housing having inner layers (111, 121) and outer layers (112, 122), the inner layers (111, 121) enclosing a cavity (13), and the outer layers (112, 122) covering the periphery of the inner layers (111, 121); a capillary structure (15) arranged in the cavity (13) and abutting against the housing; and a cooling liquid located in the cavity (13). The material of the inner layers (111, 121) is different from the material of the outer layers (112, 122), and the density of the material of the outer layers (112, 122) is lower than the density of the material of the inner layers (111, 121). According to the heat-conducting member, the inner layers (111, 121) can be made of a material with a higher density and stable chemical properties so as to guarantee the durability thereof, and the outer layers (112, 122) can be made of a material with a lower density so as to reduce the overall weight of the housing while guaranteeing the structural strength of the housing. The combination of the inner layers (111, 121) and the outer layers (112, 122) can guarantee the working stability of the heat-conducting member, guarantee the structural strength thereof to prevent damage caused by an external force, and also effectively reduce the weight of the housing thereby facilitating a lightweight design.
