Abstract

The invention discloses a metal-hydride finned heat exchanger and a manufacture method for the same. The manufacture method for the metal-hydride finned heat exchanger comprises the steps that a heat exchange tube is bent into a hairpin tube, and in-series plate connection and tube expansion are conducted; metal hydride powder is filled into the heat exchange tube and then compacted; a micropore filtration plate is installed in the heat exchange tube to fix the metal hydride powder; and a bent head is installed at an end part of the hairpin tube, and then firmly welded. According to the manufacture method for the metal-hydride finned heat exchanger disclosed by the invention, the problem that the prior art lacks a manufacture technology for batched processing and production of metal-hydride heat exchangers can be solved.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a metal hydride finned heat exchanger and a manufacturing method thereof. Background technique [0002] At present, the traditional vapor compression refrigeration / heat pump system is a large energy consumer, and its freon working medium has a destructive effect on the atmosphere. Therefore, an energy-saving and environmentally friendly refrigeration principle is urgently needed to solve the current situation. Therefore, the metal hydride refrigeration system Conceived and born. [0003] Metal hydride is a special alloy, which can reversibly absorb a large amount of hydrogen under certain temperature and pressure conditions, and release a large amount of heat of reaction. The metal hydride refrigeration system uses hydrogen as the working fluid, through the metal hydride in the Reversible reaction heat in the hydrogen absorption and desorption process to realize the ref...
