Loop heat pipe system with variable pipe diameters of heat release pipe sets

Abstract

The invention provides a loop heat pipe system with variable pipe diameters of heat release pipe sets. The system comprises heat pipes, each heat pipe comprises an evaporation part and a condensationpart, the condensation parts comprise condensation pipes and the heat release pipe sets, the multiple heat release pipe sets are arranged in the flowing direction of fluid in a fluid channel, and thepipe diameters of the heat release pipe sets are constantly increased in the flowing direction of the fluid in the fluid channel. According to the loop heat pipe system, a waste heat utilization loopheat pipe device of a novel structure is provided, it can be guaranteed that more steam enters the heat release pipe sets through the upper portions by increasing the pipe diameters of the heat release pipe sets, and it is guaranteed that in the fluid flowing direction, due to the large steam amount and the good vibration effect, overall heat exchange is uniform.

Description

technical field [0001] The invention relates to a heat pipe technology, in particular to a heat pipe with a new structure. 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 sati...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, the shape of the heat pipe affects the heat-absorbing area of ​​the evaporating end, so the heat-absorbing range of the evaporating end is generally relatively small, and sometimes it is necessary to install multiple heat pipes in the heat source to meet the heat-absorbing demand; and when there are multiple evaporating ends, Because each evaporation end is in a different position of the heat source, it will produce uneven heat absorption.

[0005] In addition, in the prior art, the waste heat utilization heat pipe device always extends the condensation end to the outside of the pipe, which occupies the external area, making the heat pipe waste heat utilization system not compact
