End butt joint type loop heat pipe

Abstract

The invention provides an end butt joint type loop heat pipe which is mainly being characterized by comprising a loop pipe body, an inserting and sleeving type butt joint part, an inserting gap and a degassing pipe. The outside of the loop pipe body is bent into a hollow square shape, and the loop pipe body comprises a first pipe end, a second pipe end and a loop section. The inserting and sleeving type butt joint part is formed in the manner that the first pipe end and the second pipe end of the loop pipe body serve as an inner pipe and an outer pipe to be inserted and sleeved oppositely in a sealed manner, and any one of the first pipe end and the second pipe end is arranged in the manner that the pipe diameter is enlarged, and provided with a pipe enlarging part. The inserting gap is formed at the position of the radial local part between the first pipe end and the second pipe end, and penetrates the outside of the inserting and sleeving type butt joint part and a loop flow pass space in the loop pipe body. The degassing pipe is inserted into the inserting gap in a close fit manner to serve as a vacuumizing and working solution pouring channel, and the outer end of the degassing pipe extends out of the inserting and sleeving type butt joint part and is provided with a closed part. The structure of the loop heat pipe can achieve practical progress of member simplification, easier and faster manufacturing, machining and forming and substantial manufacturing cost reduction, and achieve better industrial economy benefits.

Description

technical field [0001] The invention relates to a heat pipe, in particular to an innovative butt-connected loop 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. 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 form a loop form as a whole, so as to 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. T...

[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
