Internal spraying water film type heat exchange system

Abstract

The invention discloses an internal spraying water film type heat exchange system. The internal spraying water film type heat exchange system comprises a plurality of spraying assemblies, each spraying assembly comprises a spraying outer plate, an inner spraying pipe, a spraying inner plate and a baffle, the inner spraying pipe is arranged on the inner side of the upper end of the spraying outer plate, a first cavity body is formed between the inner wall of the upper end of the spraying outer plate and the inner spraying pipe, at least one inner spraying hole is formed in the side wall of the inner spraying pipe, the inner spraying hole communicates with the first cavity body, the spraying inner plate is arranged on the inner side of the lower end of the spraying outer plate, the spraying inner plate is located at the bottom of the inner spraying pipe, a second cavity body is formed between the inner side of the spraying outer plate and the outer side of the spraying inner plate, the bottom of the first cavity body communicates with the top of the second cavity body, the baffle is arranged between the bottom of the inner spraying pipe and the top of the spraying inner plate, and the baffle is in plugging fit with the bottom of the inner spraying pipe and the top of the inner side of the spraying inner plate respectively. The internal spraying water film type heat exchange system is simple in structure, convenient to manufacture and maintain and better in heat exchange effect.

Description

technical field [0001] The invention relates to the technical field of air-conditioning refrigeration or heating and cooling towers, in particular to an internal spray water film heat exchange system. Background technique [0002] Most of the outdoor unit condensers of traditional small and medium-sized household and commercial air-conditioning systems are tube-fin heat exchangers combined with copper tubes---aluminum expansion tubes. The evaporators use tube-fin heat exchangers, stainless steel plate heat exchangers, casing Type heat exchangers, etc., while large central air conditioners generally use a combination of shell-and-tube heat exchangers and outdoor cooling towers for heat exchange. In the shell-and-tube heat exchanger, the refrigerant exchanges heat with water, and the water becomes cold water or hot water, which is sent to the outdoor cooling tower to raise or cool down to the ambient temperature. Most of the heat exchangers in small and medium-sized household...

AI Technical Summary

Problems solved by technology

Most of the heat exchangers in small and medium-sized household and commercial air-conditioning systems use tube-fin heat exchangers. When the outdoor ambient temperature is higher than 35°C in cooling mode, the heat exchange effect of this type of heat exchanger is poor, and the cooling effect is poor. When the outdoor ambient temperature is lower than -15°C, there is serious frost or ice, and heat exchange is no longer possible
