PURPOSE: An evaporator for a waste water heat pump to prevent corrosion is provided to prevent the corrosion of a welded part of a tube due to liquid inside a main body, since the welded part is corroded by the liquid inside the main body. CONSTITUTION: An evaporator for a waste water heat pump comprises a main body(12), a tube sheet(14), a tube(25), a bending tube(26), a supply pipe(20), a discharge pipe(30), a fixing plate(16), and a supporting frame(18). An opening(13) is formed on one side of the main body. The tube sheet is coupled with the opening to seal the main body and comprises tube holes. The tubes are extended to the inside of the main body and are bent in a U-shape. The connection part of the tubes is exposed to the outside of the tube sheet. The bending tube is coupled with the circular connection part of the tube. The discharge pipe connects to the connection part of a tube. The support frame connects the fixing plate and the tube sheet. |
