Abstract

The invention discloses a multi-branch heat pipe based on secondary sintering molding and a manufacturing method thereof. The multi-branch heat pipe is of a vacuum closed space structure, and comprises a multi-branch pipe joint (7), a first branch pipe shell (1), a second branch pipe shell (2) and an annular sealing plug (12). According to the multi-branch heat pipe based on secondary sintering molding, heat pipe branches of the required number can be additionally arranged according to actual demands, high flexibility is achieved, and the heat pipe can be applied to the situations of concentrated heat dissipation with multiple heat sources or intensified cooling with one heat source and multiple cooling sources. The multi-branch heat pipe based on secondary sintering molding employs a sintering porous capillary core and has the excellent heat transfer performance and gravity resistance characteristics of a traditional sintering heat pipe. The multi-branch heat pipe is manufactured through secondary sintering molding, the manufacturing process is simple, mass production can be achieved, and the heat pipe is suitable for being applied and popularized on the market.

Description

technical field [0001] The invention relates to the field of electronic cooling devices, in particular to a multi-branch heat pipe based on secondary sintering molding and a preparation method thereof. Background technique [0002] In recent years, as the power of electronic devices has increased and their volumes have become smaller and smaller, heat dissipation is still one of the key issues that need to be solved urgently. The heat pipe is a two-phase phase change heat conduction element with high thermal conductivity. It has many advantages such as fast heat transfer, good isothermal performance, stable performance, and long life. Based on the characteristics of high efficiency and good flexibility, heat pipe technology is still an effective means to solve the heat dissipation of electronic devices, and is widely used in aerospace technology, solar thermal control technology, waste heat recovery and other fields. [0003] At present, most heat pipes are mainly used to d...
