Outdoor unit of refrigeration apparatus

Abstract

An outdoor unit of a refrigeration apparatus includes a heat exchanger constructed of aluminum or aluminum alloy, a floor frame supporting the heat exchanger, and a spacer disposed between the heat exchanger and the floor frame. The heat exchanger has a plurality of flat pipes, a header manifold connected to the flat pipes, and a plurality of fins joined to the flat pipes. Heat exchange occurs between a fluid flowing inside the flat pipes and air flowing outside the flat pipes. The spacer has an inclined surface and a horizontal surface. The inclined surface guides condensation from the heat exchanger to the floor frame. The horizontal surface contacts the heat exchanger and the heat exchanger is horizontally mounted on the horizontal surface.

1 . An outdoor unit of a refrigeration apparatus, the outdoor unit comprising:
 a heat exchanger constructed of aluminum or aluminum alloy, the heat exchanger having
 a plurality of flat pipes, 
 a header manifold, each of said flat pipes being connected to said header manifold, and 
 a plurality of fins joined to said flat pipes, 
 heat exchange occurring between a fluid flowing inside said flat pipes and air flowing outside said fiat pipes; 
   a floor frame supporting said heat exchanger; and   a spacer disposed between said heat exchanger and said floor frame,   said spacer having
 an inclined surface arranged and configured to guide condensation from said heat exchanger to said floor frame, and 
   a horizontal surface, said heat exchanger making contact with said horizontal surface, and said heat exchanger being horizontally mounted on said horizontal surface.   
     
     
         2 . The outdoor unit according to  claim 1 , wherein
 said fin has a water-guiding part, and said inclined surface is disposed on an elongated portion of said water-guiding part.   
     
     
         3 . The outdoor unit according to  claim 1 , wherein
 said spacer includes a drainage structure disposed on a lower part of said spacer.   
     
     
         4 . The outdoor unit according to  claim 1 , wherein
 said spacer is disposed on a lower end of a bent part of said heat exchanger.   
     
     
         5 . The outdoor unit according to  claim 1 , wherein
 said spacer includes an extended part extending diagonally upward from said horizontal surface on said spacer.   
     
     
         6 . The outdoor unit according to  claim 2 , wherein
 said spacer includes a drainage structure disposed on a lower part of said spacer.   
     
     
         7 . The outdoor unit according to  claim 6 , wherein
 said spacer is disposed on a lower end of a bent part of said heat exchanger.   
     
     
         8 . The outdoor unit according to  claim 7 , wherein
 said spacer includes an extended part extending diagonally upward from said horizontal surface on said spacer.   
     
     
         9 . The outdoor unit according to  claim 2 , wherein
 said spacer is disposed on a lower end of a bent part of said heat exchanger.   
     
     
         10 . The outdoor unit according to  claim 2 , wherein
 said spacer includes an extended part extending diagonally upward from said horizontal surface on said spacer.   
     
     
         11 . The outdoor unit according to  claim 3 , wherein
 said spacer is disposed on a lower end of a bent part of said heat exchanger.   
     
     
         12 . The outdoor unit according to  claim 3 , wherein
 said spacer includes an extended part extending diagonally upward from said horizontal surface on said spacer.   
     
     
         13 . The outdoor unit according to  claim 4 , wherein
 said spacer includes an extended part extending diagonally upward from said horizontal surface on said spacer.
