Abstract

The present invention relates to a heat sink and a preparation technology thereof. The heat sink comprises a body; the body is provided with a plurality of through holes configured to arrange heating elements; the body comprises a matrix with conductivity; the matrix is provided with an opening pore; the opening pore of the matrix is filled with phase-change materials. The heat sink and the preparation technology thereof are good in absorption of heat and energy storage effect, simple in preparation technology and low in manufacturing cost, and can ensure the stable work of the heating elements.

Description

technical field [0001] The invention relates to a heat sink, in particular to a heat sink and a preparation process thereof. Background technique [0002] With the development of modern technology and the improvement of environmental awareness, there are more and more devices and equipment driven by electric energy. In many industrial applications, electrical energy is stored and extracted through batteries or supercapacitors. Their process of storing and discharging energy is reversible, and can also be charged and discharged repeatedly. But they generate a certain amount of heat during charging or discharging. If the heat generated during charging or discharging is not removed in time, the heat will accumulate inside the battery or capacitor, causing the battery or capacitor to overheat, thereby affecting the use effect and service life of the battery or capacitor. In extreme cases, an overheated battery or capacitor, such as a lithium-ion battery, can burn or even warr...
