Outdoor unit for air conditioner

Abstract

Disclosed herein is an outdoor unit for an air conditioner which improves heat exchange performance. The outdoor unit includes a main body having a suction hole for allowing air thereinto and a discharge hole for discharging air therefrom; a heat exchanger disposed within the main body, executing heat exchange with the air flowing through the outdoor unit; a suction fan provided at the suction hole side of the main body to generate upstream air flow into the outdoor unit; and a discharge fan provided at the discharge hole side of the main body to generate downstream air flow out of the outdoor unit.

1 . An outdoor unit for an air conditioner comprising:
 a main body having a suction hole for allowing air thereinto and a discharge hole for discharging air therefrom;   a heat exchanger disposed within the main body, adapted for executing heat exchange with the air flowing through the outdoor unit;   a suction fan provided at the suction hole side of the main body and being adapted to generate upstream air flow into the outdoor unit; and   a discharge fan provided at the discharge hole side of the main body and being adapted to generate downstream air flow out of the outdoor unit.   
     
     
         2 . The outdoor unit according to  claim 1 , further comprising a controller adapted to adjust the rotational velocities of the suction fan and the discharge fan so that the upstream air flow and the downstream air flow have different velocities. 
     
     
         3 . The outdoor unit according to  claim 1 , further comprising a controller adapted to adjust the rotational velocities of the suction fan and the discharge fan so that the upstream air flow and the downstream air flow have identical velocities 
     
     
         4 . The outdoor unit according to any one of  claims 1  to  3 , wherein the suction fan is positioned at a lower portion of the outdoor unit and is adapted to generate the upstream air flow in the horizontal direction, and
 wherein the discharge fan is positioned at an upper portion of the outdoor unit and is adapted to generate the downstream air flow in the vertical direction. 
 
     
     
         5 . The outdoor unit according to one of  claims 1  to  4 , wherein a plurality of suction holes is formed on a plurality of circumferential surfaces of the main body. 
     
     
         6 . The outdoor unit according to  claim 5 , wherein the heat exchanger includes a plurality of sections facing towards the plurality of suction holes. 
     
     
         7 . The outdoor unit according to  claim 6 , wherein the main body has a rectangular parallelepiped shape and the suction holes are formed on three lateral sides of the main body. 
     
     
         8 . The outdoor unit according to  claim 7 , wherein the suction fan faces one in the middle of said three lateral sides of the main body, and
 wherein the section of the heat exchanger facing said one in the middle of three lateral sides is disposed more upstream than the suction fan in the air flow path.   
     
     
         9 . The outdoor unit according to  claim 7 , wherein the suction fan faces one in the middle of said three lateral sides of the main body, and
 wherein the section of the heat exchanger facing said one in the middle of three lateral sides is disposed more downstream than the suction fan in the air flow path.   
     
     
         10 . The outdoor unit according to  claim 9  or  10 , further comprising a compressor for compressing a refrigerant, wherein the compressor is positioned more downstream than the suction fan in the air flow path.
