Problems solved by technology

[0004] Generally, a heat pipe includes an evaporating end and a condensing end. The fluid in the evaporating section absorbs heat and evaporates, condenses at the condensing end, and transfers heat to the external fluid. Whether it is the evaporating end or the condensing end, there will be gas in the heat exchange process. In the case of liquid two-phase flow, and with the aging of the heat pipe, some non-condensable gas will be generated in the heat pipe, resulting in a decrease in the heat tr

Embodiment Construction

[0051] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0052] In this article, if there is no special explanation, when it comes to formulas, " / " means division, and "×" and "*" mean multiplication.

[0053] Such as figure 1 As shown, a heat pipe 1 includes an evaporating end 8 and a condensing end 10, and preferably also includes an adiabatic end 9. The evaporating end 8 absorbs heat, the fluid sealed in the heat pipe evaporates, and then the fluid enters the condensing end 10, and the heat is transferred through the condensing end to the outside, and then the fluid after heat exchange becomes a liquid, and then flows to the evaporation end 8.

[0054] Such as figure 2 As shown, the heat pipe 1 includes a flat tube, and the flat tube includes tube walls 3 parallel to each other, and a fluid channel 2 is formed between the adjacent tube walls 3 . Fins 7 are arranged inside the flat tube 1 ...

Abstract

The invention provides a heat pipe. The heat pipe comprises a flat pipe, wherein the flat pipe comprises pipe walls which are parallel to each other; a fluid channel is formed between the adjacent pipe walls; external fins are arranged at the outer parts of the pipe walls; and the heights of the fins are gradually reduced from the middle of the transverse section to the two sides of the flat pipe. According to the heat pipe provided by the invention, the heat dissipation of the whole heat pipe is uniform, a local temperature of the heat pipe is prevented from overheating, the heat dissipation effect is improved and the service life of the heat pipe is prolonged.

Description

technical field [0001] The invention belongs to the field of heat pipes, in particular to a heat pipe with fins arranged outside. Background technique [0002] Heat pipe technology is a heat transfer element called "heat pipe" invented by George Grover of the Los Alamos National Laboratory in the United States in 1963. It makes full use of the principle of heat conduction and the rapid The property of heat transfer, the heat of the heating object is quickly transferred to the outside of the heat source through the heat pipe, 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 rad...
