Heating power-variable gravity heat pipe

Abstract

The invention provides a heating power-variable gravity heat pipe. The heating power-variable gravity heat pipe comprises an evaporation part and a condensation part, wherein liquid absorbs heat and evaporates in the evaporation part, enters the condensation part to release the heat, and then returns to the evaporation part through gravity, and the evaporation part comprises electric heating parts. The heating power-variable gravity heat pipe is characterized in that the plurality of electric heating parts are arranged in the vertical direction, and the heating power of electric heating elements arranged in the different electric heating parts is gradually increased in the vertical direction. According to the heating power-variable gravity heat pipe, the heating uniformity and the heatingefficiency are further improved by arranging the heating power of the electric heating elements in a heating pipe to be changed in the vertical direction (namely, the direction from bottom to top).

Description

[0001] This application is a divisional application for January 29, 2019, application number 2019100861183, and invention name "a gravity heat pipe". technical field [0002] The invention relates to a gravity heat pipe, in particular to an electrically heated gravity heat pipe. Background technique [0003] 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. [0004] 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 dissipat...

AI Technical Summary

Problems solved by technology

However, in the case of using electric energy, it is generally used to simply install electric heating components in the evaporation part alone, but the electric heating efficiency is low in this case, and the prior art does not adopt specific structures or improvement measures to further improve the heating efficiency

[0006] In view of the above problems, the present invention improves on the basis of the previous invention, and provides a new gravity heat pipe, thereby solving the problem of low heating efficiency in the case of gravity heat pipe heating
