technical field [0001] The invention relates to a loop-type heat pipe, in particular to an innovative end-cap-type closed structure of the parallel connection part of the loop-type heat pipe. 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 pipe walls at both ends of the pipe body must also be drilled through secondary processing to form radial 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 The structural composition is too complicated, the manufacturing process is difficult, and the manufacturing cost is too high and does not meet the best industrial economic benefits. It is necessary to improve and break through.
