Heat exchange kit and manufacture method thereof for heat pipes

Abstract

The invention provides a heat exchange kit for heat pipes. The heat exchange kit for the heat pipes comprises a lower end plate, a middle partition plate, an upper end plate and a number of U-shaped heat pipes. The lower end plate, the middle partition plate and the upper end plate are arranged in sequence from the bottom up. The U-shaped heat pipes are installed between the lower end plate, the middle partition plate and the upper end plate in an inserted manner. The portions, between the middle partition plate and the upper end plate, of the U-shaped heat pipes are adopted as a condensationsegment, and the portions, between the lower end plate and the middle partition plate, of the U-shaped heat pipes are adopted as an evaporation segment. Heat dissipation fins are arranged in the portions, in the condensation segment and the evaporation segment, of the U-shaped heat pipes. The U-shaped heat pipes are perfused with a heat exchange working medium. The two open ends of each U-shaped heat pipe are connected in a sealed manner through a connecting bend. A connecting hole is formed in the middle of each connecting bend. The connecting holes in the connecting bends communicate with each other in sequence through metal capillary pipes, wherein the diameter of the metal capillary pipes is smaller than the diameter of the U-shaped heats pipes, and thus the U-shaped heat pipes communicate with each other. Welded sealing is adopted in the connecting positions of the connecting holes and the metal capillary pipes. According to the heat exchange kit for the heat pipes, the structureis compact; heat exchange efficiency is high; the function of countercurrent heat exchange is achieved; and meanwhile, arrangement space is saved, and heat exchange is smooth and successful.

Description

technical field [0001] The invention relates to the technical field of heat exchange, in particular to a heat pipe heat exchange kit and a manufacturing method thereof. Background technique [0002] Heat pipe technology has been widely used in aerospace, military and other industries before. In the existing flue gas emission, the flue gas takes away a large amount of heat, which wastes energy and pollutes the environment. A large number of heat pipes are used in flue gas waste heat recovery heat exchangers. Heat pipes have high heat exchange efficiency. In order to increase heat exchange efficiency, finned heat pipes are generally used. In general, a heat pipe includes an evaporation end and a condensation end. The fluid in the evaporation end absorbs heat and evaporates, and condenses at the condensation end to transfer heat to the external fluid. With the development of electronic technology, more and more miniaturized electronic devices also need to dissipate heat. Ther...

Problems solved by technology

However, the existing finned heat pipes are all made of a single piece. On the one hand, the installation process is more complicated and the cost is relatively high. The compact internal space of thermal equipment is not conducive to the optimization and selection of installation space
