FIN-TUBE TYPE HEAT EXCHANGER

摘要

PURPOSE: A fin-tube type heat exchanger is provided to improve heat transfer performance and to efficiently discharge condensed water. CONSTITUTION: A heat exchanger includes a plurality of platy fins having holes(3) formed thereon and arranged at regular intervals, granular parts vertically and lengthily formed between the holes and having both ends differently sloping and a plurality of slits(6) having both sides cut protrusively formed thereon in same direction and at same heights forming slit groups(5) formed by the slits of same numbers arranged between the holes and layered on each other; and tubes passing the holes formed on the fins to comply to the tubes and contact with the fins so that refrigerant flowing therein exchanges heat with the fins.
