Description

technical field [0001] The invention relates to the technical field of heat transfer, in particular to a flat liquid-absorbing core with a composite structure and a manufacturing method thereof. Background technique [0002] With the rapid development of electronic equipment, the power of electronic chips continues to increase, and its structure is increasingly miniaturized, which leads to a sharp increase in the heat flux of electronic chips, and the problem of chip failure due to excessive temperature is becoming more and more serious. How to improve electronic chips The ability to dissipate heat has become one of the key factors considered in the design of electronic devices. [0003] Compared with traditional air-cooled radiators, flat heat pipes and vapor chambers use the principle of phase change heat transfer, which has higher heat dissipation capacity and efficiency, and can meet the heat dissipation requirements of high-power electronic components. The working prin...
