Abstract

The invention relates to an integrated heat pipe preparation method and device, belonging to the technical field of heat pipe preparation. The preparation method is: during the process of spinning and sealing the unsealed end of the heat pipe, vacuum is first carried out, and then after filling the working medium under the condition of negative pressure inside the heat pipe, the spin sealing is continued until the end of the heat pipe is reached. The head is completely sealed. The device includes a vacuuming and working medium filling device and a spinning head. The lower end of the spinning head is inverted cone shape, with a friction layer attached to the inner wall of the cone. The vacuuming and working medium filling device is embedded inside the spinning head and passes through the inverted cone. On the top of the conical friction layer, the lower end of the spinning head is connected to the unsealed end of the heat pipe. The method and device of the present invention can realize the integration of liquid filling, vacuuming and sealing of the heat pipe. The equipment is simple, the cost is low, and the degree of automation is strong. It can further increase the heat pipe preparation efficiency and reduce the production cost.

Description

technical field [0001] The invention relates to a heat pipe integrated preparation process and an interface device, especially at normal temperature, which can be used for the integrated preparation of heat pipes with various specifications such as vacuuming, filling material and sealing. The invention belongs to the technical field of heat pipe preparation. Background technique [0002] In many heat transfer and cases, the heat pipe is one of the most effective heat transfer elements known, it can transmit a large amount of heat through its small cross-sectional area for a long distance without external power. Since the 1970s, heat pipe technology has developed rapidly. Scientific research institutions, colleges and universities, companies and factories and mines in various countries have carried out various development and application research. International, regional and national exchanges of heat pipe technology have become increasingly frequent. [0003] With the rapid...
