PURPOSE: An indoor heat exchanger is provided to prevent the resistance of air flow by naturally draining the compensate water generated on the surface of a corrugated fin arranged in an indoor heat exchanger and to improve the performance of the heat exchanger by increasing the air wind. CONSTITUTION: A cooling cycle is composed of a compressor, an outdoor heat exchanger, an expansion valve and an indoor heat exchanger. A fan is installed on a proper position adjacent to the indoor heat exchanger to blow the air of normal temperature to the indoor heat exchanger. Also, the indoor heat exchanger is made up of a couple of header pipes(41), tubes(42) and corrugated fins(43). The corrugated fins have plural slits and a curved part installed with a specific inclination angle to drain water. Therefore, refrigerants of low temperature and pressure are introduced into the indoor heat exchanger through the expansion valve, and then distributed through the tubes so the corrugated fins arranged between the tubes as to keep the cold state through the cold refrigerants flowing into the tubes.
