Embodiment 1

[0034] Embodiment 1: The shell material of the heat pipe is aluminum-based D97, and the filling working fluid is acetone. The preparation method is to first vacuumize the unsealed end of the heat pipe 6 during the spinning and sealing process, and then fill the working medium under the condition of negative pressure inside the heat pipe 6, and then continue to spin and seal until the heat pipe 6 The ends are completely sealed. The heat pipe 6 is a heat pipe pipe with one end sealed. As shown in the drawings, the preparation device includes a vacuum pumping and filling material device and a spinning head 4. The lower end of the spinning head 4 is an inverted cone, and a friction layer 5 is attached to the inner wall of the cone. The device is embedded in the spinning head 4 and passes through the top of the inverted cone-shaped friction layer 5, and the lower end of the spinning head is connected to the unsealed end of the heat pipe 6; the vacuuming and filling medium device i...

Abstract

The invention relates to an integral preparation method and device for a thermotube, belonging to the technical field of thermotube preparation. The preparation method comprises the following steps of firstly vacuumizing an unsealed end head of a thermotube in the process of spinning sealing the unsealed head end, and then filling a working substance in the thermotube under the subpressure condition of the internal part of the thermotube, and then spinning sealing the end head until the end head of the thermotube is fully sealed. The device comprises a vacuumizing and working substance filling device and a spinning seal head; the lower end of the spinning seal head is of an inverted cone shape; a friction layer is adhered to the internal wall of the cone; the vacuumizing and working substance filling device is embedded in the spinning seal end and penetrates the top of the inverted cone shaped friction layer; and the lower end of the spinning seal head is connected with the unsealed end head of the thermotube. By adopting the method and device provided by the invention, fluid-filling, vacuumizing and sealing can be integrally realized for the thermotube; the equipment is simple, the cost is low, the automation degree is high, the preparation efficiency of the thermotube can be further improved, and the production cost can be reduced.

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...
