PURPOSE:To reduce air blowing noise and improve a heat exchanging efficiency by a method wherein a disturbance of heat exchanging air passing through a heat exchanger is prevented, a difference between the maximum distance and the minimum distance for the heat exchanger and the blower fan is shortened to reduce a suction pressure difference. CONSTITUTION:There are provided a heat exchanger 5 comprised of heat radiation fins 12 and heat exchanging pipes 13, and a lateral blower fan 7 having a circular section. A main body 1 of the device has suction ports 2a, 2b at its front surface and an upper surface and a diffuser 4 at a front lower surface. The heat exchanger 5 forms an inverted V-shape as viewed in a side elevational view and acts as a connecting member for the front side heat exchanger 5A and the rear side heat exchanger 5B. The front side heat exchanger 5A is provided with a plurality of recesses, it is bent at the recesses to have the same bent angle and, they are bent and formed to enclose the lateral flow fan 7. |
