High-efficient radial heat pipe for heat transfer and finned pipe thereof

Abstract

The invention relates to the technical field of a heat pipe, and discloses a high-efficient radial heat pipe for heat transfer and a finned pipe thereof. The high-efficient radial heat pipe for heat transfer comprises a first layer inner pipe, a second layer inner pipe and an outer pipe which have different diameters; the first layer inner pipe and the second layer inner pipe are formed to be a double-layered inner pipe, and the second layer inner pipe is sleeved in the first layer; the outer pipe is sleeved with a double-layered inner pipe; the first layer inner pipe is connected with the second layer inner pipe; the middle of the first layer inner pipe and the outer pipe is a sealing structure and formed to be an annular channel heat pipe; the working medium of the first layer inner pipe can perform heat exchange with the working medium of the annular channel heat pipe; the channel heat pipe exchanges heat with the outer part; the working medium of the double-layered inner pipe is circulated at one end of the high-efficient radial heat pipe for heat transfer for realizing the countercurrent flow of the same working medium at the same side of the double-layered heat pipe; the inner pipe fin is arranged on the first layer inner pipe.

Description

technical field [0001] The invention relates to the technical field of heat pipes, in particular to a high-efficiency radial heat transfer heat pipe and its finned pipe. Background technique [0002] Mineral energy is becoming increasingly scarce today, and the human living environment is also severely damaged, especially the emission of greenhouse gases. The problems of the human living environment are becoming more and more prominent. It is an indisputable fact that island countries threaten the safety of coastal cities. The increasingly serious smog problem in our country has not been solved for a long time, which has seriously affected people's health and increased the chances of people suffering from lung cancer. The serious smog phenomenon is difficult to fundamentally solve. The exhaust gas is increasing day by day, but the spontaneous factors in nature itself are rare. We also know that more than 80% of the energy used by human beings needs to go through the proces...

AI Technical Summary

Problems solved by technology

The inventor noticed that the radial heat transfer heat pipe has many incomparable advantages over the traditional gravity heat pipe. In terms of the use of existing products, the sleeve heat pipe not only has low production cost, but also has 1.2 times the heat exchange efficiency of the traditional gravity heat pipe. Although there are more than a dozen patents for the invention of the sleeve radial heat transfer heat pipe at home and abroad, no three-layer sleeve heat pipe has been found.
