Flexible heat pipe structure and manufacturing method thereof

Abstract

The invention discloses a flexible heat pipe structure and a manufacturing method thereof. The structure of the heat pipe includes a first pipe, a second pipe, a flexible segment, a capillary organization and a working fluid. The first pipe and the second pipe are arranged with an interval. The flexible segment is connected with the first pipe and the second pipe respectively, and includes an annular flexible body and a soft coating. The annular flexible body is connected with the first pipe and the second pipe. The soft coating is lap joined to the first pipe and the second pipe, and is arranged around the outside of the annular flexible body. The capillary organization is arranged inside the first pipe, the second pipe and the annular flexible body. The working fluid is filled inside the first pipe, the second pipe and the soft coating. Besides, the invention also provides a manufacturing method of the flexible heat pipe structure, so the structure of the flexible heat pipe enables the heat pipe to be bended to any angle or direction at will according to actual usage requirements, and the structure can be maintained in a normal state without producing the hardening phenomenon after being bended and adjusted repeatedly.

Description

technical field [0001] The invention relates to a heat pipe, in particular to a bendable heat pipe structure and a manufacturing method thereof. Background technique [0002] As the computing speed of the computer's processor (such as: CPU) continues to increase, the heat generated by it is also getting higher and higher. In the past, the cooling device composed of heat sink and fan is obviously unable to meet the needs of the current processor. Therefore, some manufacturers combine the heat pipe with the heat pipe radiator of the heat sink, which can effectively overcome the heat dissipation problem of the current processor. However, the existing heat pipes still have many problems to be solved, such as the limitation of space usage in the surrounding environment, and the inventors made innovations and improvements to the heat pipes based on the aforementioned problems to be overcome. [0003] The existing heat pipe mainly includes a metal pipe body, a capillary structure ...

AI Technical Summary

Problems solved by technology

[0004] When these heat pipes are actually used, most of them are bent into an "L" or "U" shape in consideration of factors such as the space use limitation of the surrounding environment and the heat transfer of multiple points. The final heat pipe often has adverse effects such as peeling or falling off of the internal capillary structure and the inner wall of the metal pipe body, which greatly reduces the heat transfer efficiency.

Moreover, most of these bent heat pipes can only be bent once. When the heat pipe is bent twice, it will usually cause cracks in the metal pipe body and be scrapped; there is indeed room for improvement.
