Outdoor unit of refrigeration apparatus

Abstract

An outdoor unit a refrigeration apparatus includes an aluminum or aluminum alloy heat exchanger, an aluminum or aluminum alloy bracket having a securing portion attached directly to the heat exchanger and a fixing portion with a through hole used to fix the bracket to a non-aluminum metal structural part, a non-metal component interposed between the fixing portion of the bracket and the structural part to create a non-contact state, a non-aluminum metal anchoring part, and an anchored structure cooperating with the anchoring part to fasten a fixing portion of the bracket to the structural part via the non-metal component. The anchoring part has an outer shape smaller than the through hole in the fixing portion. The non-metal component maintains, in astute in which the anchoring part is passing through the through hole in the fixing portion, a non-contact state between the bracket and the anchoring part.

1 . An outdoor unit ( 2 ) of a refrigeration apparatus comprising
 a heat exchanger constructed of aluminum or aluminum alloy;   a bracket constructed of aluminum or aluminum alloy, the bracket including a securing portion attached directly to the heat exchanger and a fixing portion having a through hole used to fix the bracket to a structural part constructed of non-aluminum metal;   a non-metal component interposed between the fixing portion of the bracket and the structural part that are fixed to one another such that the fixing portion of the bracket and the structural part are in a non-contact state;   an anchoring part constructed of non-aluminum metal, the anchoring part having an outer shape smaller than the through hole in the fixing portion; and   an anchored structure cooperating with the anchoring part to fasten the fixing portion of the bracket to the structural part via the non-metal component,   the non-metal component maintains, in a state in which the anchoring part is passing through the through hole in the fixing portion, a non-contact state between the bracket and the anchoring part.   
     
     
         2 . The outdoor unit of the refrigeration apparatus according to  claim 1 , further comprising
 a casing constructed of non-aluminum metal, the casing housing the heat exchanger and being the structural part.   
     
     
         3 . The outdoor unit of t le refrigeration apparatus according to  claim 2 , wherein
 the non-metal component has a sandwiching structure that sandwiches sides the fixing portion of the bracket, and   the anchoring part and the anchored structure fasten together the sandwiching structure of the non-metal component and the fixing portion of the bracket.   
     
     
         4 . The outdoor unit of the refrigeration apparatus according to  claim 3 , wherein
 the anchoring part is a male screw constructed of non-aluminum metal, and   the anchored structure is one of
 a nut separate from the structural part, the nut being configured to anchor the male screw, 
 an attachment plate having a screw hole, the attachment plate being configured to anchor the male screw, and 
 a female-threaded portion in the non-metal component, the female-threaded component being configured to anchor the male screw. 
   
     
     
         5 . The outdoor unit of the refrigeration apparatus according to  claim 4 , wherein
 the anchored structure is the attachment plate having the screw hole, and the screw hole in the attachment plate is burred.   
     
     
         6 . The outdoor unit of the refrigeration apparatus according to  claim 1 , wherein
 the bracket has a plurality of the fixing portions.   
     
     
         7 . The outdoor unit of the refrigeration apparatus according to  claim 2 , wherein
 the bracket has a plurality of the fixing portions.   
     
     
         8 . The outdoor unit of the refrigeration apparatus according to  claim 3 , wherein
 the bracket has a plurality of the fixing portions.   
     
     
         9 . The outdoor unit of the refrigeration apparatus according to  claim 4 , wherein
 the bracket has a plurality of the fixing portions.   
     
     
         10 . The outdoor unit of the refrigeration apparatus according to  claim 5 , wherein
