Abstract

The invention provides a pipe-end butt joint type loop heat pipe and a forming method thereof. The pipe-end butt joint type loop heat pipe mainly comprises components in a structural plane as follows: a hollow pipe body, an inserting joint part, a sleeve joint part, a tight fit zone and a loose fit zone, wherein the hollow pipe body comprises two pipe ends and a loop zone, and loop channel space in the loop zone is in a vacuum closed state and accommodates a working solution; the inserting joint part is arranged at one pipe end of the hollow pipe body; the sleeve joint part is arranged at the other end of the hollow pipe body, and is assembled on the periphery of the inserting joint part in a sleeving manner; the tight fit zone is arranged in one local zone at the inserting and sleeving part of the inserting joint part and the sleeve joint part, and a tight insertion airtight state is formed between the inserting joint part and the sleeve joint part through the tight fit zone; the loose fit zone is arranged in the other local zone at the inserting and sleeving part of the inserting joint part and the sleeve joint part, and a gap is formed between the inserting joint part and the sleeve joint part through the loose fit zone. According to the pipe-end butt joint type loop heat pipe and the forming method thereof, the loop heat pipe can realize practical progress that components and manufacturing forming steps are greatly simplified, the manufacturing cost is greatly reduced and better heat dissipation efficiency is kept, and has better industrial economic benefits.

Description

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 structure and its 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
