Hot-fin heater exchanger

Abstract

The hot finned plate heat exchanger as one new type of heat exchanger is one important mechanism for recovering exhausted wind energy of large air conditioning system, recovering afterheat of high temperature fume and dissipating heat of computer CPU. Its structure includes vacuum liquid-filled end plates and core body, the vacuum liquid-filled end plates are set on two sides of the vacuum liquid-filled passage, and the core body sonsists of the vacuum liquid-filled passage and several finned plate passages. Each of the vacuum liquid-filled passages and the finned plate passages has upper andlower partition boards, side sealing tapes and internal fins. Each of the finned plate passages is separated by one sealing tapes into two parallel hot medium passage and one cold medium passage. After being assembled, the heat exchanger is arranged obliquely or vertically.

Description

technical field [0001] The hot fin plate heat exchanger of the invention relates to a novel heat exchanger, which is an important device for recovering exhaust energy of a large-scale air-conditioning system, recovering residual heat from high-temperature flue gas, and dissipating heat from a computer CPU. Background technique [0002] Existing large-scale air-conditioning systems, such as subway central air-conditioning systems, large-scale building central air-conditioning systems, and large-scale factory central air-conditioning systems, consider that the allowable pressure drop of the wind is very small, and adopt cross-flow plate-fin heat exchangers, which have low efficiency. , The disadvantages of large volume, light weight, and difficult space layout. The high-temperature flue gas waste heat recovery device uses a heat pipe heat exchanger, which is large in size, high in cost, and difficult in space layout. It is made of copper and aluminum, which cannot withstand hi...
