Abstract

By inserting a capillary tube with whiskers into a conventional vertical heat pipe, the upward force of the refrigerant caused by the capillary phenomenon is enhanced by the whiskers inside, and heat exchange can be performed spontaneously by utilizing the force of the refrigerant vaporized by the warm heat source above to press the refrigerant liquid surface. In addition, when the lower part is a warm heat source, the whiskers on the outer wall of the capillary tube and the whiskers on the wall surface can be used as a heat pipe for heat exchange.

Description

Technical Field

[0001] The present invention is a heat pipe formed by inserting a capillary tube with whiskers into a conventional vertical heat pipe. When the upper part is a warm heat source, the refrigerant can circulate spontaneously in a certain direction through the capillary tube; when the lower part is a warm heat source, it works as a conventional heat pipe. Background Art

[0002] In the past, vertical heat pipes were only used to utilize geothermal energy to melt snow.

[0004] Patent documents: None

[0005] Non-patent documents: None Summary of the invention

[0006] Problems to be solved by the invention:

[0007] A vertical heat pipe can effectively circulate refrigerant liquid when the lower part is a warm heat source, but when the upper part is a warm heat source, the downward force of the refrigerant is heated, and the upward force of the refrigerant is weakened, which deteriorates the efficiency.

[0008] Solution to the problem:

[0009] By inserting a capillary tube with a wick installed in a conventional heat pipe, when the upper part is a warm heat source, the upward force of the refrigerant caused by the capillary phenomenon is enhanced by the internal wicks, and by utilizing the force of the refrigerant vaporized by the upper warm heat source to press the refrigerant liquid surface, a flow in a certain direction that causes the refrigerant liquid to rise in the capillary tube is created, thereby enabling spontaneous heat exchange. In addition, when the lower part is a warm heat source, due to the wicks on the outer wall of the capillary tube, the surface area of ​​the wicks is increased compared to a normal heat pipe, thereby becoming a high-efficiency heat pipe.

[0010] Effects of the invention:

[0011] According to the present invention, efficient heat exchange can be performed regardless of whether the heat source of the heat pipe is at the upper part or the lower part, and thus the present invention can be applied to geothermal utilization, heat transport in high-rise buildings, and the like. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In order to achieve efficient heat exchange in either case where the heat source is at the top or the bottom, a capillary tube with whiskers is embedded in the body. In addition, the size of the body, the size, number, and arrangement of the capillary tubes, the height of the refrigerant liquid level, the type of refrigerant, etc. can be changed according to the scale, etc.
