Abstract: PURPOSE: A radiating structure of a PCB(Printed Circuit Board) for an air conditioner is provided to maximize a radiating effect and reduce a size of an air conditioner. CONSTITUTION: A heat sink(60) is mounted in front of a heat exchanger(50). The heat exchanger(50) includes refrigerant pipes(51) and fins(52) through which the pipes(51) pass. The distance between the fins(52) which are disposed in right rear of the heat sink(60) are larger than that between the fins which are not aligned with the heat sink(60), thereby forming a large-spaced portion(50a). The air passing through the large-spaced portion(50a) flows faster than the air passing through other portion of the heat exchanger(50). Therefore, the quantity of the air flowing toward the heat sink(60) is increased. Also, since the temperature of the air passing through the large-spaced portion(50a) of the heat exchanger(50) and flowing toward the heat sink(60) is relatively low, the radiating efficiency of the heat sink(60) is enhanced.
