Embodiment Construction

[0040] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0041] In this article, if there is no special explanation, when it comes to formulas, " / " means division, and "×" and "*" mean multiplication.

[0042] like 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, condenses after exchanging heat in the condensation header 2, and 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 device...

Abstract

The invention provides a rod-fin type loop heat pipe with varying sizes. The rod-fin type loop heat pipe includes an evaporation header, a condensation header, rising pipes and return pipes, flow stabilizing devices are arranged in the rising pipes, the flow stabilizing devices each include a core body and an outer shell, the core bodies are arranged in the outer shells, the outer shells are connected and fixed to the inner walls of the rising pipes, the core bodies each include a plurality of radial rods extending from the centers of the core bodies to the radial direction, and a plurality offins extending downwards from the radial rods are arranged on each radial rod; and the core bodies each include a core column arranged at the center of each core body, one ends of the radial rods arefixed into the core columns, and from the core columns of the rising pipes to the radial extension direction, the size of the fins on the same radial rods is getting larger and larger. According to the rod-fin type loop heat pipe with the varying sizes, the size of the fins on the rising pipe walls is increased, so that the ability to cut vapor phases and liquid phases near the pipe walls is enhanced. The ability to cut near the pipe walls is focused to be strengthened, and noise reduction and vibration damping can be targeted for specific situations, so that the effects of noise reduction and vibration damping are further achieved, and meanwhile, heat transfer can be further enhanced.

Description

technical field [0001] The invention belongs to the field of heat pipes, in particular to a heat exchange heat pipe. 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 obtain a satisfacto...
