Bionic phase change energy storage steam cavity module

Abstract

The invention relates to a bionic phase change energy storage steam cavity module which comprises a tree-shaped steam cavity and a phase change container. The tree-shaped steam cavity comprises at least one steam cavity flat plate, a columnar steam cavity and multiple groups of branch and trunk steam cavity structures. One surface of the steam cavity flat plate is in contact with a heat source so that heat concentrated by the heat source can be uniformly diffused to the surface of the steam cavity flat plate, and the other surface of the steam cavity flat plate is packaged with the outer surface of the phase change container. The columnar steam cavity is connected with the steam cavity flat plate, and the multiple groups of branch and trunk steam cavities are arranged around the columnar steam cavity and each provided with two or more branch and trunk steam cavity branches extending towards the space. The multiple groups of branch and trunk steam cavities are connected through multiple layers of annular steam cavity ribs. Internal channels of the steam cavity flat plate, the columnar steam cavity, the branch and trunk steam cavities and the annular steam cavity ribs are communicated with one another, the internal spaces are filled with phase change working media, and the inner surfaces are provided with porous capillary structures. The tree-shaped steam cavity structure is arranged in the phase change container, and other parts in the phase change container are filled with phase change materials.

Description

Technical field [0001] The present invention relates to the field of thermal management technology of electronic components, and more particularly to a high energy density high-efficiency heat dissipation system. Background technique [0002] There are three main heat storage technologies, including thermal storage, latent heat storage and thermochemical storage. The latent heat storage system has the characteristics of high energy storage density, small temperature variation, has been successfully applied to solar thermal utilization, industrial waste recycling, building energy saving, electronic equipment heat dissipation. However, the thermal conductivity of the phase change material used in the latent heat storage system will severely impair the storage and release rate of thermal energy. The enhancement method currently used can be divided into three types: one is to enhance the thermal conductivity of the phase change material using porous media and nanoparticles, such as f...
