Abstract

The invention relates to a heat pipe and a manufacturing method thereof. The manufacturing method specifically comprises the following steps of: S1: filling metallic filaments into a metal pipe, wherein the metallic filaments account for 30-70 percent of the holding capacity of the metal pipe; S2: extruding the metal pipe until the holding capacity of the metal pipe is reduced, and forming capillary openings between the metallic filaments and the inner wall of the metal pipe as well as between adjacent metallic filaments; and S3: filling working medium in the extruded metal pipe, and sealing two ends of the metal pipe, so as to obtain the heat pipe. In the invention, the pipe is made of metallic material, capillary core structures are made of the metallic filaments, the metallic filaments are compactly arranged in the pipe through extrusion to form even and compact capillary holes, therefore enough capillary force can be provided, and the heat exchange efficiency of the heat pipe is improved.

Description

technical field [0001] The invention relates to a heat pipe and a manufacturing method thereof, belonging to the technical field of heat exchange. Background technique [0002] A heat pipe is a passive heat transfer element with high thermal conductivity. It is generally composed of a tube, a capillary core arranged in the tube, and an end cap that seals the tube. Working medium such as freon. The heat pipe utilizes the principle of phase change and capillary action to transmit a large amount of heat over a long distance through its small cross-sectional area without external power. Specifically, the heat pipe absorbs heat at the evaporating end, and the working fluid phase changes into a gas and is transported to the cooling end. After the working fluid is condensed into a liquid at the cooling end, the working fluid is returned to the evaporating end through the capillary force provided by the capillary structure, thereby Heat transfer microcirculation is formed in the h...
