STRUCTURE FOR ARRANGING COOLING FINS OF FIN-TUBE INTEGRATED TYPE HEAT EXCHANGER LETTING AIR SMOOTHLY FLOW AROUND FIN-TUBE

摘要

PURPOSE: A structure for arranging cooling fins of a fin-tube integrated type heat exchanger is provided to improve the cooling performance by letting air smoothly flow, thereby improving the efficiency of heat exchange. 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. The cooling fins are inclined toward a center part of a heat exchanger at an angle of 10-20 deg. on a base of a direction vertical to the refrigerant pipes, wherein the cooling fins are symmetrically formed to minimize flow resistance of air exchanging heat.
