A heat pipe with variable vertical pipe diameter

Abstract

The invention provides a heat pipe with vertical pipes with regularly changing pipe diameters. The heat pipe comprises a vertical part, a horizontal part and the vertical pipes, wherein the bottom endof the vertical part communicates with the horizontal part. The horizontal part extends to the direction away from the vertical part from the bottom end of the vertical part. The lower portion of thehorizontal part communicates with the multiple vertical pipes, wherein the vertical pipes are evaporation ends of the heat pipe. The vertical part is a condensation end of the heat pipe. The verticalpipes and the horizontal part are arranged in a smoke channel. Pipe diameters of the multiple vertical pipes are smaller and smaller in the smoke flowing direction. A novel heat pipe structure is provided, the structure of the evaporation ends of the heat pipe is improved, thus pipe diameters of the vertical pipes are different according to different positions, heat absorption can be further met,and waste heat absorption ability is improved.

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.
