Multi-channel plate-fin dew-point indirect evaporative cooling heat exchanger

Abstract

The invention relates to a multi-channel plate-fin dew-point indirect evaporative cooling heat exchanger, which comprises a bracket and a dew-point heat exchange core; the dew-point heat exchange core is formed by orderly adjoining a plurality of heat exchange units, wherein each heat exchange unit is divided by a separation plate and is formed by orderly adjoining a moist air channel, a heat medium channel, a moist air channel and a dry air channel; at least a layer of horizontal laminate is arranged in the heat medium channel; a vertical fin is arranged in the moist air channel; and a plurality of pores for communicating the moist air channels are arranged on the separation plates on both sides of the dry air channel. The multi-channel plate-fin dew-point indirect evaporative cooling heat exchanger is formed by combining a plurality of channels, the moist air channels and the dry air channel which are connected in parallel to exchange heat in countercurrent manner are used for cooling the heat medium in the heat medium channel; the heat exchange efficiency is improved, the air or the liquid medium can be cooled to a temperature close to an air dew point; the multi-channel plate-fin dew-point indirect evaporative cooling heat exchanger can realize more temperature drop in comparison with other evaporative cooling heat exchanger, which can reduce the energy resource consumption to achieve the aim of energy conservation and emission reduction.

Description

technical field [0001] The invention relates to a heat exchange device, in particular to a multi-channel plate-fin dew point indirect evaporative cooling heat exchanger. Background technique [0002] In 2003, Russian scholar Dr. Valeriy Maisotsenko proposed a new cycle theory of thermodynamics named after him. It uses the natural refrigeration of water to evaporate and absorb heat in the air to cool down the gas or liquid medium. It can be used without the use of compressors and refrigerants. Cool any gaseous or liquid medium to a temperature close to the dew point of air. In our country, research on the application of the above-mentioned theories has begun to appear and has gradually deepened. Various experimental dew point indirect evaporative cooling heat exchangers and other dew point indirect evaporative coolers have entered the testing stage, and there are also some related national patents, but they have not yet been published.

Problems solved by technology

In our country, research on the application of the above-mentioned theories has begun to appear and has gradually deepened. Various experimental dew point indirect evaporative cooling heat exchangers and other dew point indirect evaporative coolers have entered the testing stage, and there are also some related national patents, but they have not yet been published. It has been effectively applied in engineering practice, especially there is no dew point indirect evaporative cooling heat exchanger that can be effectively used for evaporative refrigeration in industrial engineering and ordinary civil projects, so as to effectively reduce energy consumption and energy saving and emission reduction.

In addition, the indirect evaporative cooling heat exchanger commonly used in the prior art adopts the structure of two channels of humid air and heat medium, and the heat exchange efficiency is low, and it is impossible to directly cool the cooled medium to the air dew point temperature
