Abstract

The invention provides a liquid distributing disc structure, an evaporator and an air-conditioner. The liquid distributing disc structure comprises a liquid uniformizing disc (1) which is provided with at least one annular liquid uniformizing hole set (11). Each liquid uniformizing hole set (11) comprises a first circle center (111) and multiple liquid uniformizing holes (112) uniformly distributed around the first circle center in an annular shape. Each annular liquid uniformizing hole set (11) can correspond to one heat exchange pipe (5) and distributes liquid into the heat exchange pipe (5)through the multiple liquid uniformizing holes (112). By means of the liquid distributing disc structure, it can be ensured that liquid refrigerant is uniformly distributed into a heat exchange pipebundle, flow of the refrigerant in all evaporation pipes is distributed uniformly, the heat exchange area is utilized optimally, the heat exchange effect is good, and the heat exchange efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, and in particular relates to a liquid distribution plate structure, an evaporator and an air conditioner. Background technique [0002] The falling-film evaporators of existing commercial air-conditioning units are usually of horizontal structure. The upper part of the housing is provided with a refrigerant distributor, and the lower part of the refrigerant distributor is provided with certain regularly arranged evaporation tubes. The tube-side medium is a refrigerant, and the shell-side medium is a refrigerant. The refrigerant that enters the upper part of the housing from the inlet and is equipped with a refrigerant distributor, drops to the wall of the evaporation tube in the lower part through the small hole on the refrigerant distributor, and the refrigerant flows outside the wall of the evaporation tube to form a Thin film, endothermic evaporation. In the ordinary vertical falli...
