A loop heat pipe of a porous flow stabilization device

Abstract

The invention provides a heat pipe. The heat pipe comprises an evaporation header, a condensation header, an ascending pipe and a reflux pipe; the ascending pipe communicates with the evaporation header and the condensation header; the evaporation header is positioned at the lower part; the condensation header is positioned at the upper part; a fluid absorbs heat for evaporation in the evaporation header, is fed in the condensation header by the ascending pipe, and is condensed in the condensation header after heat exchange; the condensed fluid is returned to the evaporation header through the reflux pipe; current stabilizing devices are arranged in the ascending pipe; multiple current stabilizing devices are arranged in the same ascending pipe; and in the height direction of the ascending pipe, gaps between the adjacent current stabilizing devices are continuously reduced. Through the gap change of the current stabilizing devices, when steam-liquid two-phase flowing exists in the ascending pipe, the heat transfer is intensified, meanwhile, the vibration of the ascending pipe is weakened, and the noise level is lowered.

Description

technical field [0001] The invention belongs to the field of heat pipes, in particular to a heat exchange heat pipe. Background technique [0002] Heat pipe technology is a heat transfer element called "heat pipe" invented by George Grover of Los Alamos National Laboratory in the United States in 1963. It makes full use of the principle of heat conduction and phase change medium. The rapid heat transfer properties of the heat pipe quickly transfer the heat of the heating object to the heat source, and its thermal conductivity exceeds that of any known metal. [0003] Heat pipe technology was widely used in aerospace, military and other industries before. Since it was introduced into the radiator manufacturing industry, people have changed the traditional radiator design ideas and got rid of the single heat dissipation mode that only relies on high air volume motors to obtain better heat dissipation. The use of heat pipe technology enables the radiator to obtain a satisfacto...

AI Technical Summary

Problems solved by technology

However, it was found during the operation of this device that the space A formed between the three pipes is relatively small because the pipes are tightly combined, because the space A is formed by the convex arc of the three pipes, so most of the space A Narrowness will make it difficult for the fluid to enter and pass through, resulting in a short circuit of the fluid, which affects the heat transfer of the fluid and cannot play a good role in stabilizing the flow

Simultaneously because the many tubes of above-mentioned structure are combined together, manufacture difficulty

[0007] In view of the above problems, the present invention has been improved on the basis of the previous invention, and a new heat pipe is provided, thereby solving the problems of low heat transfer coefficient and uneven heat transfer in the case of heat pipe heat exchange
