Heat pipe heat storage heat exchanger with pipe diameter change of communicating pipe

Abstract

The invention provides a heat pipe heat storage heat exchanger with a pipe diameter change of communicating pipes. The heat exchanger comprises a gravity heat pipe, the heat pipe comprises an evaporation end and a condensation end; the evaporation end is arranged in a heat accumulator, and the heat accumulator is arranged in a heat source; the condensation end is arranged in a container of a coldsource, the evaporation end comprises a plurality of end parts, and the plurality of communicating pipes are arranged between every adjacent end parts; and the diameter of the communicating pipes is continuously increased in the direction from the center of the heat accumulator to the outer wall of the heat accumulator. Through the change of the pipe diameter of the communicating pipes, the pressure balance can be achieved as soon as possible in the fluid heating process.

Description

technical field [0001] The invention relates to a heat exchanger technology, in particular to a heat pipe heat storage heat exchanger. 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 o...

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 the current heat pipe heat accumulator, gravity heat pipes are basically used, and because the diameter of the evaporating end of the condensing end of the heat pipe is the same, the heating area is small, and the heat exchange area cannot be better expanded. Therefore, in view of the above problems, the present invention is Improvements are made on the basis of the previous invention, and a new heat pipe heat accumulator is provided. Through the change of heat storage capacity, the heat exchange effect is further improved, the heat source is fully utilized, and the energy consumption is reduced.
