Hot pipe of which pipe through holes are communicated with one another

Abstract

The invention provides a hot pipe. The hot pipe comprises an evaporation collector, a condensation collector, a rising pipe and a return pipe; the rising pipe is communicated with the evaporation collector and the condensation collector, the evaporation collector is located at the lower portion, the condensation collector is located at the upper portion, and fluid absorbs heat and evaporates in the evaporation collector, enters the condensation collector through the rising pipe, and condensates after being subjected to heat transfer in the condensation collector; the condensed fluid returns tothe evaporation collector through the return pipe; flow stabilizing devices are arranged in the rising pipe, small holes are formed in adjacent through holes, and communication of the through holes is achieved through the small holes. Through the formation of the small holes, it can be guaranteed that the adjacent through holes are communicated with one another, pressure among the through holes can be made uniform, so that the fluid of a high-pressure flow channel flows to low pressure; meanwhile, a liquid phase and a gas phase can be further separated when the fluid flows, and stabilizationof two-phase flowing is further promoted.

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
