Pipe end butt joint type loop type heat pipe

Abstract

A pipe end butt joint type loop type heat pipe mainly comprises a hollow pipe body, an inserting connection part, a sleeved connection part, a close fit area segment and a loose fit area segment, wherein the hollow pipe body comprises two pipe ends and a loop type area segment, and a loop type runner space in the hollow pipe body is in a vacuum closed state and contains work liquid; the inserting connection part is arranged at one pipe end of the hollow pipe body; the sleeved connection part is arranged at the other pipe end of the hollow pipe body, and the sleeved connection part is used for being assembled on the periphery of the inserting connection part in a sleeving manner; the close fit area segment is arranged on one local area segment of the portion where the inserting connection part and the sleeved connection part are inserted and sleeved, and the inserting connection part and the sleeved connection part are in a closely-inserted gastight state through the close fit area segment; and the loose fit area segment is arranged on the other local area segment of the portion where the inserting connection part and the sleeved connection part are inserted and sleeved, and a gap is formed between the inserting connection part and the sleeved connection part through the loose fit area segment. The loop type heat pipe can achieve the practical progress that a component is formed, the manufacturing and forming steps are substantially simplified, the manufacturing cost is substantially reduced and good cooling performance is maintained, and good industry 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. 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
