Dew point plate type indirect evaporation cooler

Abstract

The invention relates to a dew-point plate indirect evaporative cooling unit, comprising plate cooling unit core comprised by pre-cooling segment and cooling segment connected with each other and water supply device. Folded interlayers in pre-cooling and cooling segments are used to form the air channel. A first air channel is formed between light faces collocated oppositely and a second air channel is formed between rough faces collocated oppositely. Interlayers for multiple rolled ripple flow channels in horizontal flow are set in the interlayer of the first air channel. Interlayers for multiple rolled bending flow channels are set in the interlayer of the second air channel. Multiple via holes are set under the inner interlayer in cooling segment and a groove is folded at the top of interlayer forming the first air channel. The water supply device comprises spraying water pipe and water storing pool under and above pre-cooling segment and cooling segment and the water storing pool is spaced by clapboard between pre-cooling segment and cooling segment. The structure in invention makes the heat exchanging efficiency be improved greatly. The temperature of outputting air approaches the dew-point and water film of wet channel wall is distributed evenly.

Description

technical field [0001] The invention belongs to the technical field of air-conditioning and refrigeration, and relates to an evaporative cooler for air-conditioning, in particular to a plate-type indirect evaporative cooler capable of reducing the air temperature to a temperature close to the dew point. Background technique [0002] In recent years, due to the shortage of energy and the increase in energy consumption of air conditioners, coupled with the increasingly serious environmental pollution and the improvement of people's requirements for living comfort, there is an urgent need to develop energy-saving, healthy, environmentally friendly, and economical heating and air-conditioning equipment. [0003] At present, most indirect evaporative coolers use the temperature difference between the dry and wet bulbs of the air to cause or expand the heat transfer temperature difference. This kind of indirect evaporative cooler that makes the air temperature close to the wet bulb...

Problems solved by technology

[0003] At present, most indirect evaporative coolers use the temperature difference between the dry and wet bulbs of the air to cause or expand the heat transfer temperature difference. This kind of indirect evaporative cooler that makes the air temperature close to the wet bulb temperature has a small temperature drop, and its application range is limited. very restrictive
