Problems solved by technology

[0009] However, the loop heat pipe can solve some of the problems of the single-pipe heat pipe, but because of its complex structure, many parts (such as fixing parts, etc.) Proposals for simple and low-cost single-pipe heat pipes are clearly out of the question

Embodiment Construction

[0063] In the following description, in order to obtain the consistency of the technical explanation of the present invention, in different embodiments, if there are components with the same function but slightly different shapes, the same names and reference numerals are still used.

[0064] The main method of the present invention is to collect the liquid working fluid flowing down the tube wall in the condensing part of the single-tube heat pipe at the place far away from the main heat-absorbing area of ​​the bottom end of the heat pipe, and use an external bypass return pipe to transport it back to the bottom of the heat pipe. The main heat-absorbing area is then used for heat-absorbing; thereby, before the condensed liquid working fluid slides down to the bottom of the heat pipe, it is evaporated first due to the heating of the rising steam and the wall surface, so that the bottom of the heat pipe is caused by the lack of liquid. Replenishing makes it dry faster, causing t...

Abstract

A semi-return heat-pipe structure comprises a long and thin hollow pipe main body and a return pipe. The inside space of the hollow pipe main body wall is divided into a bottom section, a middle section and a top section. A sump for collecting the liquid flowed along the pipe wall is set on the middle section pipe wall. The upper opening of the return pipe is connected to the sump so as to guide out the liquid in the sump. The lower opening of the return pipe recovers the guided-out liquid to the bottom section of the hollow pipe main body.

Description

technical field [0001] The invention relates to an improved single-pipe heat pipe structure, in particular to a semi-loop heat pipe structure with a branch liquid return pipeline. Background technique [0002] The use of heat pipes in the prior art mainly uses the two-phase change of evaporation and condensation of the working fluid contained in the heat pipe to carry out the heat transfer operation between the environments where the two ends of the heat pipe are located; please refer to figure 1 as shown, figure 1 It is a schematic cross-sectional view of the operation of a heat pipe 1 in the prior art, wherein the heat pipe 1 is made of a material with high thermal conductivity (such as copper) to form a closed pipe structure 10, and a certain amount of water is contained in the closed space connected in the pipe. The working fluid11. The production of the heat pipe 1 usually firstly seals one end of the tube body structure 10 and opens the other end, and pumps air at th...
