Heat exchange unit

Abstract

A heat exchange unit includes: a heat exchanger in which flat tubes are stacked at predetermined intervals in a thickness direction by a heat transfer fin; and a first member that is attached to the heat exchanger and that restricts a movement of the heat exchanger. The first member includes a body and a protrusion portion protruding from the body. The protrusion portion is disposed between adjacent flat tubes of the heat exchanger.

What is claimed is: 
     
         1 . A heat exchange unit comprising:
 a heat exchanger in which flat tubes are stacked at predetermined intervals in a thickness direction by a heat transfer fin; and   a first member that is attached to the heat exchanger and that restricts a movement of the heat exchanger, wherein   the first member includes a body and a protrusion portion protruding from the body, and   the protrusion portion is disposed between adjacent flat tubes of the heat exchanger.   
     
     
         2 . The heat exchange unit according to  claim 1 , wherein
 the first member includes a plurality of protrusion portions.   
     
     
         3 . The heat exchange unit according to  claim 1 , wherein
 the heat exchanger includes a plurality of first heat exchange sections, and   the first member includes a plurality of protrusion portions for each of the plurality of first heat exchange sections.   
     
     
         4 . The heat exchange unit according to  claim 1 , wherein
 the protrusion portion has a columnar shape.   
     
     
         5 . The heat exchange unit according to  claim 1 , wherein
 the protrusion portion includes a pawl portion configured to engage with at least one of the adjacent flat tubes.   
     
     
         6 . The heat exchange unit according to  claim 5 , wherein
 the pawl portion is configured to engage with an end portion of the at least one of the adjacent flat tubes.   
     
     
         7 . The heat exchange unit according to  claim 5 , wherein
 the pawl portion is configured to engage with end portions of the adjacent flat tubes.   
     
     
         8 . The heat exchange unit according to  claim 1 , wherein
 the first member comprises resin.   
     
     
         9 . The heat exchange unit according to  claim 1 , wherein
 the first member comprises metal and a resin coating that is applied to a surface of the first member.   
     
     
         10 . The heat exchange unit according to  claim 1 , wherein
 the first member comprises metal and an insulating rubber that is attached to a surface of the first member.   
     
     
         11 . The heat exchange unit according to  claim 1 , further comprising:
 a casing; and   a second member fixed to the casing, wherein   the first member is fixed to the second member by screw fastening or engagement.   
     
     
         12 . The heat exchange unit according to  claim 1 , further comprising:
 a casing; and   a second member fixed to the casing, wherein   a fixing portion the second member is fixed to an opening of the first member.   
     
     
         13 . The heat exchange unit according to  claim 1 , further comprising:
 a casing, wherein   the first member is fixed to the casing.   
     
     
         14 . The heat exchange unit according to  claim 1 , wherein
 the body of the first member is in contact with the heat transfer fin.   
     
     
         15 . The heat exchange unit according to  claim 1 , wherein
 the heat exchanger further includes a header that connects end portions of the flat tubes to each other, and   the body of the first member is in contact with the header.   
     
     
         16 . The heat exchange unit according to  claim 1 , wherein
 the heat exchanger includes a second heat exchange section, in which a thickness direction of flat tubes in the second heat exchange section is inclined with respect to a vertical direction, and   the first member is attached to the heat exchanger vertically below the second heat exchange section.
