Evaporating heat exchanger with moistened surface

Abstract

The present invention relates to one kind of evaporating heat exchanger for air conditioner and other refrigerating equipment and aims at solving the problems of low heat efficiency and short service life of heat exchanger. The present invention includes blower, water sprayer, heat dissipating metal sheet, metal pipe passed through and fixed to the heat dissipating sheet, and non-woven cloth on the outer surface of the heat dissipating sheet. It has the advantages of high heat efficiency, large evaporation area, low power consumption, etc. and can make air conditioner and other refrigerating system run at low-pressure difference and low power consumption of compressor. The surface of the heat exchanger can maintain moisture for long time and the water sprayer may run intermittently.

Description

technical field [0001] The invention relates to a heat exchanger for air conditioners and other refrigeration equipment, in particular to a surface wetting evaporative heat exchanger. Background technique [0002] There are three types of air-cooled, water-cooled, and water-evaporated heat exchangers used in existing air conditioners as condensers. The air-cooled heat exchanger is easy to install and use, but it works in a state of high temperature and high temperature difference higher than the ambient temperature. High temperature and high temperature difference correspond to high pressure and high pressure difference. The compressor of the current air conditioner works at high pressure and high pressure difference. root. The cooling effect of water-cooled condenser is better, but it is limited in some areas due to high water consumption. Even if it is applied to ground energy air conditioning, it will also be restricted by the fact that groundwater cannot be exploited ar...

AI Technical Summary

Problems solved by technology

However, due to the hygroscopic material installed between the cooling fins and the metal heat transfer tubes, the heat transfer efficiency between the heat transfer tubes and the fins is reduced, and the increased evaporation area has not been fully utilized. In addition, this structure has a large flow resistance and is easy to scale. And accumulation of dust, maintenance is difficult, the hygroscopic material on both sides of the heat sink is not firmly connected, and the service life is short

In order to prevent the heat sink from being compressed and deformed, the heat exchanger is equipped with fixed plates at the left and right ends. The tightness of the fixed plates directly affects the quality and appearance of the heat exchanger. The structure is complex but still unstable.
