Problems solved by technology

When the traditional copper plate shell is further thinned, the material strength will be weakened. The vapor chamber is more prone to warping, bending and other deformations under the action of thermal stress or other external forces, which will affect the thermal and mechanical properties of the product.

Abstract

The invention belongs to the technical field of design and manufacturing of soaking plates, and particularly relates to an ultrathin soaking plate with high strength and light weight. The ultrathin soaking plate with high strength and light weight comprises an upper cover plate and a lower cover plate, wherein the periphery of the upper cover plate and the periphery of the lower cover plate are hermetically connected to form a sealed working medium cavity, the sealed working medium cavity is in a vacuum state and is filled with a liquid working medium, the upper cover plate and the lower coverplate are made of composite materials, the lower surface of the upper cover plate and the upper surface of the lower cover plate are concave surfaces, a plurality of support columns are arrayed in the concave surfaces, and a liquid absorbing core is arranged on the concave surface of the lower cover plate. According to the ultrathin soaking plate with high strength and light weight, the upper cover plate and the lower cover plate are both composed of three layers of composite materials, mechanical strength and deformation resistance can be guaranteed while thin plate shell materials are thinned, and mechanical properties and heat dissipation effects of the ultra-thin soaking plate in a limited space are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of soaking plate design and manufacture, and in particular relates to a high-strength and light-weight ultra-thin soaking plate. Background technique [0002] As a high-efficiency phase change heat transfer element, vapor chamber has been widely used in various terminal electronic products such as mobile phones and computers. With the thinning and thinning of electronic products, the vapor chamber is developing towards the trend of ultra-thin large plane. When the traditional copper plate shell is further thinned, the material strength will be weakened. The vapor chamber is more prone to warping, bending and other deformations under the action of thermal stress or other external forces, which will affect the thermal and mechanical properties of the product. . Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a high-strength and light-weight ultra...
