Outdoor unit of air conditioner

Abstract

An outdoor unit in which, by installing small fans near the ventilation surface of a heat exchanger so as to be parallel with the ventilation surface of the heat exchanger and arranging the small fans so that the ventilation areas of the small fans and the heat exchanger are equivalent, the number of small fans that can be installed is maximized while reducing power consumption.

What is claimed is: 
     
         1 . An outdoor unit of an air conditioner comprising a heat exchanger, and a plurality of the fans installed side by side in a vicinity of the ventilation surface of the heat exchanger. 
     
     
         2 . The outdoor unit of an air conditioner according to  claim 1 , wherein the fans and the heat exchanger are obliquely installed when viewed from the front of a housing, and the fans are located near the ventilation surface of the heat exchanger so that the ventilation area of the fans and the ventilation area of the heat exchanger are equivalent. 
     
     
         3 . The outdoor unit of an air conditioner according to  claim 1 , further comprising a guide blade that changes the wind direction, wherein the installation angle of the guide blade is changed depending on the installation position so that the ventilation resistance from the intake port to the exhaust port of the outdoor unit is the same for each of the plurality of fans. 
     
     
         4 . The outdoor unit of an air conditioner according to  claim 1 , wherein the number of fans installed is determined so that the total fan power is equal to or less than an allowable value. 
     
     
         5 . The outdoor unit of an air conditioner according to  claim 1 , wherein each of the fans is driven by a DC power source. 
     
     
         6 . An outdoor unit of an air conditioner comprising:
 a heat exchanger that exchanges heat between air to be cooled and a refrigerant; and   a plurality of fans arranged along a ventilation surface intersecting the passage direction of the air to be cooled in the heat exchanger.   
     
     
         7 . The outdoor unit of an air conditioner according to  claim 6 , wherein the entire ventilation surface of the heat exchanger is covered by the plurality of fans.
