Abstract
A spray type heat-exchanging unit includes a main body; a distributive refrigerant spray module located in an upper part of the main body and having an extended distributor and a refrigerant spray surface; and a plurality of heat exchange tubes provided in the main body below the distributive refrigerant spray module. A liquid refrigerant is guided into the extended distributor to drip onto the refrigerant spray surface, and then uniformly sprayed onto the heat exchange tubes. Gaseous refrigerant produced by evaporation in heat exchange in the main body is recovered via a top opening of the main body, making the mechanical refrigerating apparatus more efficient than a refrigerating apparatus adopting a flooded evaporator, and minimizing the refrigerant charge amount and material cost required by the heat-exchanging unit.
