Outdoor unit of air conditioner

Abstract

An outdoor unit of an air conditioner includes: a housing having a box shape, the housing being made of first metal; a heat exchanger disposed in the housing and fixed to the housing via a non-conductive material, at least part of the heat exchanger being made of second metal, the second metal being different in spontaneous potential from the first metal; and a conductive material made of nonmetal, the conductive material being disposed in the housing. The conductive material is fixed to the housing and electrically connected to the housing, and is electrically connected to the heat exchanger.

1 . An outdoor unit of an air conditioner, comprising:
 a housing, made of first metal, having a box shape;   a heat exchanger disposed in the housing and fixed to the housing via a non-conductive material, at least part of the heat exchanger being made of second metal, the second metal being different in spontaneous potential from the first metal; and   a conductive material made of nonmetal, the conductive material being disposed in the housing, wherein   the conductive material is fixed to the housing and electrically connected to the housing, and is electrically connected to the heat exchanger.   
     
     
         2 . The outdoor unit of an air conditioner, according to  claim 1 , wherein
 the housing includes:
 a housing floor panel; 
 a housing top panel disposed above the housing floor panel; 
 a housing front panel configured to couple the housing floor panel with the housing top panel; 
 a housing rear panel; and 
 housing side panels, wherein 
   the conductive material is fixed to at least one of the housing floor panel, the housing top panel, the housing front panel, the housing rear panel, and the housing side panels.   
     
     
         3 . The outdoor unit of an air conditioner, according to  claim 1 , wherein
 a spontaneous potential of the first metal is higher than a spontaneous potential of the second metal.   
     
     
         4 . The outdoor unit of an air conditioner, according to  claim 1 , wherein
 the first metal is iron or iron alloy, and   the second metal is aluminum or aluminum alloy.   
     
     
         5 . The outdoor unit of an air conditioner, according to  claim 1 , wherein
 the heat exchanger is a parallel-flow heat exchanger.   
     
     
         6 . The outdoor unit of an air conditioner, according to  claim 2 , wherein
 the heat exchanger is a parallel-flow heat exchanger.   
     
     
         7 . The outdoor unit of an air conditioner, according to  claim 3 , wherein
 the heat exchanger is a parallel-flow heat exchanger.   
     
     
         8 . The outdoor unit of an air conditioner, according to  claim 4 , wherein
 the heat exchanger is a parallel-flow heat exchanger.
