STRUCTURE FOR INSTALLING DEFROSTING SENSOR OF FIN-TUBE INTEGRATED TYPE HEAT EXCHANGER

摘要

PURPOSE: A structure for installing a defrosting sensor of a fin-tube integrated type heat exchanger is provided to completely remove the remaining frost by detecting a temperature of an upper end of a frost area, thereby improving the performance of a heat exchanger. CONSTITUTION: Refrigerant pipes(101) are formed in two columns to pass a refrigerant. Cooling fins(102) are formed integratedly with the refrigerant pipes. The refrigerant pipes are repeatedly bent in S shape and both ends of the refrigerant pipes are fixed by supports(103). A defrosting heater(104) is installed to surround lower parts of the supports and the refrigerant pipes. A defrosting sensor(105) is installed at a right side of an upper end of a frost area where the remaining frost exists.
