Abstract:
1. A spray type heat-exchanging unit, comprising: a main body defining an internal receiving space and a top opening communicating with said receiving space; a plurality of heat exchange tubes provided in a lower part of said receiving space of said main body; and a distributive refrigerant spray module provided in said main body above said heat exchange tubes, and including an extended distributor, a liquid refrigerant inlet, one or more openings and a refrigerant spray surface; said extended distributor being provided with a plurality of apertures, and said liquid refrigerant inlet being provided on a top of said extended distributor for guiding a liquid refrigerant into said extended distributor, so that said liquid refrigerant drips onto said refrigerant spray surface via said apertures on said extended distributor and be sprayed onto said heat exchange tubes, wherein said spray surface of said distributive refrigerant spray module is provided on a top thereof with impact absorbing material selected from a group consisting of chemical fiber non-woven fabrics, plant fiber non-woven fabrics, net fabrics, metal wool and non-metal wool, wherein said liquid refrigerant sprayed onto said heat tubes conducts heat exchange with said heat exchange tubes, and is vaporized into gaseous refrigerant, which flows out of said main body via said top opening of said main body, and wherein said one or more openings are defined by said extended distributor, said refrigerant spray surface and one or more splash covers, such that a first pressure in the distributive refrigerant spray module is the same as a second pressure in the lower part of said receiving space due to gaseous refrigerant exhausted through the one or more openings.
