Embodiment Construction

[0047] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0048] In this article, if there is no special explanation, when it comes to formulas, " / " means division, and "×" and "*" mean multiplication.

[0049] Such as figure 1 A heat pipe shown includes an evaporation header 1, a condensation header 2, a rising pipe 3 and a return pipe 5, the rising pipe 3 communicates with the evaporation header 1 and the condensation header 2, and the evaporation header 1 Located in the lower part, the condensation header 2 is located in the upper part, the fluid absorbs heat and evaporates in the evaporation header 1, enters the condensation header 2 through the riser 3, and condenses after exchanging heat in the condensation header 2, the condensed fluid Return to the evaporation header 1 through the return pipe 5; a flow stabilization device 4 is arranged in the riser pipe 3, and the flow stabilization dev...

Abstract

The invention provides a design method for the fin size of a loop heat pipe. The design method of the fin comprises the following steps that a plurality of fins are arranged on the same radial rod, the fins have the same shape, the distance between the fins and a central rod is S1, the size of the fins is C1, and C1 is a function of the distance S1, namely C1 = F4 (S1), which satisfies the following requirements that C1 '> 0, wherein C1 'is a primary derivative of C1. According to the design method for the fin size of the loop heat pipe, the cutting ability in the vicinity of the pipe wall canbe emphasized, noise reduction and shock absorption can be carried out in a targeted manner, the noise reduction and damping effect is further achieved, and meanwhile, heat transfer can be further enhanced.

Description

[0001] The present invention is a divisional application with the filing date of August 03, 2017, the application number 2017106556240, and the title of the invention "a loop heat pipe". technical field [0002] The invention belongs to the field of heat pipes, in particular to a heat exchange 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 o...
