PURPOSE:To reduce noise by a constitution wherein water in a drain pan is sprinkled between an air guider and a heat exchanger by a slinger ring provided on a propeller fan for cooling the heat exchanger and then it is gathered by a water-driving plate and driven to the heat exchanger. CONSTITUTION:When a propeller fan 5 rotates, a slinger ring 8 scrapes up the water gathered in a drain pan 7. The water thus raised up is all driven to a heat exchanger 10 along a water-driving plate 9 provided between an air guider 6 and the heat exchanger 10. Accordingly, the water is made free from being sprinkled from a suction louver as is the case in a conventional device, and thereby the generation of noise can be prevented, while the efficiency of the heat exchanger can be increased. |
