Embodiment Construction

[0026] figure 1 is a schematic front view of a sintered heat pipe according to an embodiment of the present invention. Such as figure 1 shown, and refer to figure 2 ; The embodiment of the present invention provides a sintered heat pipe 200 with a novel structure, which has high heat dissipation or cooling efficiency, can be applied to various heat exchange devices, and is especially suitable for heat sources with high heat flux such as semiconductor refrigeration chips 150 To dissipate heat. Specifically, the sintered heat pipe 200 may include a main pipe section 210 with both ends closed. In particular, a bifurcated pipe section 220 extends from one or more positions on opposite sides of the main pipe section 210 to improve the heat dissipation or cooling efficiency of the sintered heat pipe 200 . The working chamber 230 of each bifurcated pipe section 220 can communicate with the working chamber 230 of the main pipe section 210 to facilitate the flow of steam in the si...

Abstract

The invention relates to a sintered heat pipe and a semiconductor refrigeration refrigerator provided with the same. The sintered heat pipe comprises a main pipe section with two ends enclosed; a branched pipe section extends from one portion of two sides opposite to the main pipe section or branched pipe sections respectively extend form a plurality of portions of two sides opposite to the main pipe section; the working cavity of each branched pipe section is communicated with the working cavity of the main pipe section. In addition, the invention further provides a semiconductor refrigeration refrigerator provided with the sintered heat pipe. Provided with the branched pipe sections, the sintered heat pipe and the semiconductor refrigeration refrigerator provided with the same have significant differences as compared with a traditional sintered heat pipe extending along a single path, heat dissipation or chill transferring efficiency is obviously improved for the sintered heat pipe, and the sintered heat pipe is especially suitable for heat dissipation of high heat flux of a semiconductor chilling plate and the like.

Description

technical field [0001] The invention relates to a sintered heat pipe, in particular to a sintered heat pipe and a semiconductor refrigeration refrigerator with the sintered heat pipe. Background technique [0002] Sintered heat pipe is a high-efficiency heat transfer element, which transfers heat through the phase change process of evaporation and condensation of liquid in a fully enclosed vacuum tube, with extremely high thermal conductivity and excellent isothermal properties. The sintered heat pipe is composed of a tube shell, a liquid-absorbing core and an end cover. After pumping the inside of the tube into a negative pressure of 1.3×(10 minus 1-10 minus 4) Pa, it is filled with an appropriate amount of working liquid, so that the liquid-absorbing core close to the inner wall of the tube The capillary porous material is filled with liquid and then sealed. One end of the sintered heat pipe is an evaporation section (heating section), and the other end is a condensation ...
