Outdoor unit for air-conditioning apparatus

Abstract

Provided is an outdoor unit for an air-conditioning apparatus, including: a casing having an opening formed at a rear surface side thereof; and a heat exchanger having a flat surface region formed into a planar shape, and being accommodated in the casing so that the flat surface region is exposed through the opening formed at the rear surface side of the casing. A side edge portion of the opening formed at the rear surface side is formed at a position opposed to the flat surface region, and is bent toward the heat exchanger side so as to narrow a gap between the side edge portion and the heat exchanger.

1 . An outdoor unit for an air-conditioning apparatus, comprising:
 a casing having an opening formed at a rear surface side thereof; and   a heat exchanger having a flat surface region formed into a planar shape, and being accommodated in the casing so that the flat surface region is exposed through the opening formed at the rear surface side of the casing,   wherein a side edge portion of the opening formed at the rear surface side is formed at a position opposed to the flat surface region, and is bent toward the heat exchanger side.   
     
     
         2 . An outdoor unit for an air-conditioning apparatus of  claim 1 , wherein the heat exchanger comprises an L-shaped heat exchanger having a curved surface region connected to the flat surface region, and a side surface region connected to the curved surface region. 
     
     
         3 . An outdoor unit for an air-conditioning apparatus of  claim 2 , wherein the side edge portion is formed at a boundary between the curved surface region and the flat surface region of the L-shaped heat exchanger. 
     
     
         4 . An outdoor unit for an air-conditioning apparatus of  claim 2 , wherein the casing has a ventilation hole formed in a side surface opposed to the side surface region. 
     
     
         5 . An outdoor unit for an air-conditioning apparatus of  claim 1 , wherein the heat exchanger comprises a flat heat exchanger formed into a flat plate shape. 
     
     
         6 . An outdoor unit for an air-conditioning apparatus of  claim 5 , wherein the casing has a side surface formed of a flat plate for blocking ventilation of air. 
     
     
         7 . An outdoor unit for an air-conditioning apparatus of  claim 1 ,
 wherein the casing has a rear surface portion for covering a part of the rear surface side, and   wherein the rear surface portion has a ventilation hole formed therein.
