Gravity heat tube

Abstract

The invention provides a gravity heat tube which comprises an evaporating end and a condensing end. The evaporating end comprises a plurality of end parts. A plurality of communicating tubes are arranged between adjacent end parts in the height directions of the end parts, the distance from the communicating tubes to the uppermost ends of the end parts is S, the tube diameter of the end part is R,R is equal to Z(S), Z(S) is a function that R changes along with S and meets the following demands: R' is less than 0, wherein R' is a primary derivative of Z(S). Through change of the distance fromthe tube diameter to the evaporating end, a fluid can reach pressure balance as soon as possible in a flowing process.

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.
