HEAT EXCHANGER OF AIR CONDITIONER

摘要

PURPOSE: A heat exchanger of an air conditioner is provided to discharge frost generated in a plurality of louver joints groups by forming at least one drain hole in the louver joint groups formed with a plurality of corrugated heating fins, thereby increasing heat transferring efficiency between the louver joint groups and air by surface contact and making air flow smooth by decreasing pressure lowering amount. CONSTITUTION: A heat exchanger of an air conditioner includes at least one drain hole(80) formed in a plurality of louver joint groups(70) for easily discharge frost generated in the louver joint groups, wherein a single drain hole is formed in a center part of a slanted surface with relation to the respective louver joints(71,72,73) of the plurality of louver joint groups or a plurality of drain holes are formed in the center part of the slanted surface with a predetermined interval.
