Gravity assisted heat pipe with communication pipe diameters variational

Abstract

The invention provides a gravity assisted heat pipe with the communication pipe diameters variational. The heat pipe comprises an evaporation end and a condensing end. The evaporation end comprises aplurality of end portions. A plurality of communication pipes are arranged between the adjacent end portions from the lower portions to the upper portions of the end portions. The diameters of the communication pipes are gradually increased from the lower portions to the upper portions of the end portions. According to the gravity assisted heat pipe, through variation of the communication pipe diameters, a greater communication area is guaranteed; and as flowing upwards, fluid is continuously heated, heating in different heat collecting pipes is increasingly nonuniform as the fluid is continuously heated, and therefore, through the arrangement, it can be guaranteed that pressure balancing is achieved as soon as possible during flowing of the fluid.

Description

technical field [0001] The invention relates to a heat pipe technology, in particular to a heat pipe with balanced internal pressure distribution. 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 r...

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.
