Segmented-heating heat tube

Abstract

The invention provides a segmented-heating heat tube. The heat tube comprises a lower header, an upper header, a heat exchange tube bundle and reflux tubes, and the heat exchange tube bundle communicates with the lower header and the upper header; the lower header is an evaporation end, and a condensation end comprises the upper header; a fluid absorbs heat and evaporates in the lower header and condenses in the upper header, and the condensed fluid returns to the lower header through the reflux tubes; the reflux tubes are connected with the end parts of the two sides of the lower header and the upper header; and an electric heating device is arranged in the lower header, the electric heating device is divided into a plurality of sections, and different sections adopt different heating power. According to the heat tube, the structure size of the electric heating device is in segmented change, so that the heating efficiency is further improved, and the heat exchange efficiency of the heat tube is improved.

Description

technical field [0001] The invention belongs to the field of heat pipes, in particular to a coil 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 satisfactory heat e...

AI Technical Summary

Problems solved by technology

[0004] The heat pipes in the prior art are in a static state during the heat exchange process, relying only on the heat dissipation at the condensing end of the heat pipe, the improvement of many inventions is only the improvement of the heat transfer enhancement structure at the condensing end

On the other hand, in the prior art, different heating powers are not used for different positions of the heat pipe, resulting in low efficiency of the heat pipe

[0005] In view of the above problems, the present invention provides a new heat pipe, so as to solve the problems of low heat transfer coefficient and uneven heat transfer in the case of heat pipe heat exchange
