Method for forming loop type heat pipe with pipe ends in butt joint

Abstract

The invention discloses a method for forming a loop type heat pipe with the pipe ends in butt joint. The method mainly comprises the step that a hollow pipe body is taken, wherein the hollow pipe body comprises the two pipe ends, a loop type segment, an insertion portion, a sleeving portion, a tight-fit segment and a loose-fit segment, and a loop type runner space inside the hollow pipe body is in a vacuum closed state and contains a working solution; the insertion portion is arranged at one of the pipe ends of the hollow pipe body; the sleeving portion is arranged at the other pipe end of the hollow pipe body, and the sleeving portion is used for being assembled to the outer circumference of the insertion portion in a sleeving manner; the tight-fit segment is arranged at one local segment of an insertion and sleeving part between the insertion portion and the sleeving portion, and through the tight-fit segment, the insertion portion and the sleeving portion are mutually in the tight-insertion airtight state; and the loose-fit segment is arranged at the other local segment of the insertion and sleeving part between the insertion portion and the sleeving portion, and through the loose-fit segment, a gap is formed between the insertion portion and the sleeving portion. By means of the method for forming the loop type heat pipe with the pipe ends in butt joint, the loop type heat pipe can achieve the practical and advancement performance that constituent components and production formation steps are substantially simplified, manufacturing cost is substantially lowered, and good heat dissipation efficiency is maintained; and good industrial economic benefits are achieved.

technical field [0001] The invention relates to a loop-type heat pipe; in particular, it refers to an innovative technology of a pipe-end butt-connected loop-type heat pipe forming method. Background technique [0002] In view of the internal structure design of the early heat pipe, the steam flow path and the condensate flow path were arranged in the same pipe section space and were arranged in an overlapping state, so that the flow directions conflicted with each other and hindered each other, resulting in reduced heat dissipation efficiency and other problems.

Problems solved by technology

[0002] In view of the internal structure design of the early heat pipe, the steam flow path and the condensate flow path were arranged in the same pipe section space and were arranged in an overlapping state, so that the flow directions conflicted with each other and hindered each other, resulting in reduced heat dissipation efficiency and other problems. The industry has developed a loop-type heat pipe structure. In this heat pipe structure, the steam flow path and the condensate flow path are set in different sections in the heat pipe space, and the overall form of a loop form can solve the aforementioned problems.

[0003] However, the existing loop-type heat pipe structure that can be seen at present still has its shortcomings. The two ends are spaced apart from each other, and a base is set between the two ends. The base is provided with a connecting channel, and the two ends of the pipe body must be provided with through holes in advance to communicate with the connecting channel. In this way, the ring-shaped loop space form inside the existing loop-type heat pipe can be formed; however, this type of existing loop-type heat pipe shape is still found in the practical application experience of the industry, because the base must be separately manufactured and processed. Moreover, the two ends of the pipe body must also be drilled through secondary processing to form through holes, and then the alignment and assembly work between the base and the two ends of the pipe body must be performed, so overall, there is still a structure that is too complicated , Difficulty in manufacturing, processing and forming, and high manufacturing costs that do not meet the best industrial economic benefits and other problems and shortcomings, it is necessary to improve and break through
