Heat exchanger

Abstract

A heat exchanger according to one aspect of the present disclosure includes: a case having at least a pair of walls; and a partition member having ends supported by the pair of walls, the partition member dividing an internal space of the case into a first flow path and a second flow path. A fluid flowing through the first flow path and a fluid flowing through the second flow path flow in a flow direction along a direction in which the walls face each other, and exchange heat with each other via the partition member. The partition member has a corrugated shape in a direction intersecting the flow direction, and the wall includes a corrugated support surface that supports the end of the partition member, the support surface having a predetermined width in the flow direction.

What is claimed is: 
     
         1 . A heat exchanger, comprising:
 a case having at least a pair of walls; and   a partition member having ends supported by the pair of walls, the partition member dividing an internal space of the case into a first flow path and a second flow path, wherein   a fluid flowing through the first flow path and a fluid flowing through the second flow path flow in a flow direction along a direction in which the walls face each other, and exchange heat with each other via the partition member,   the partition member has a corrugated shape in a direction intersecting the flow direction, and   the wall includes a corrugated support surface that supports the end of the partition member, the support surface having a predetermined width in the flow direction.   
     
     
         2 . The heat exchanger according to  claim 1 , wherein
 the partition member includes a first corrugated surface in contact with the fluid flowing through the first flow path and a second corrugated surface in contact with the fluid flowing through the second flow path,   the wall includes:   a first wall portion facing at least the first flow path in the flow direction; and   a second wall portion protruding from the first wall portion toward the internal space of the case, and wherein   the second wall portion includes the corrugated support surface that is configured to support the end of the partition member at the second corrugated surface.   
     
     
         3 . The heat exchanger according to  claim 2 , further comprising a sealing layer, wherein
 the sealing layer is formed by a filler disposed in a space surrounded by the support surface of the second wall portion, an inner surface of the first wall portion facing the first flow path, and an inner surface of the case defining the first flow path, and   the end of the partition member is arranged to be embedded in the sealing layer.   
     
     
         4 . The heat exchanger according to  claim 3 , wherein
 the second corrugated surface and the support surface are disposed with a gap therebetween, and   a portion of the sealing layer is formed within the gap and is configured to support the end of the partition member.   
     
     
         5 . The heat exchanger according to  claim 1 , wherein
 the partition member and the case are integrally configured.   
     
     
         6 . The heat exchanger according to  claim 1 , wherein
 the partition member is configured by a plurality of interconnecting plates.   
     
     
         7 . The heat exchanger according to  claim 6 , wherein
 the plurality of plates are interconnected by brazing.   
     
     
         8 . The heat exchanger according to  claim 6 , wherein
 the plurality of plates are interconnected by caulking.   
     
     
         9 . The heat exchanger according to  claim 1 , wherein
 the partition member is configured by a plurality of interconnecting aluminum sheets.   
     
     
         10 . The heat exchanger according to  claim 2 , wherein
 at least one of the first corrugated surface and the second corrugated surface includes at least a pair of convex portions arranged to face each other and abut against each other.   
     
     
         11 . The heat exchanger according to  claim 2 , wherein
 the first wall portion of at least a first wall includes an opening communicating with the second flow path.   
     
     
         12 . The heat exchanger according to  claim 11 , wherein
 the case includes a wall surface extending toward the first wall and being inclined outward from the case, and   the wall surface faces the second corrugated surface and is connected to the opening.   
     
     
         13 . The heat exchanger according to  claim 2 , wherein
 the case includes a first wall surface facing the first corrugated surface, and   the first wall surface includes an opening through which the fluid flowing through the first flow path enters and exits the case.   
     
     
         14 . The heat exchanger according to  claim 2 , wherein
 the case includes a second wall surface facing the second corrugated surface, and   the second wall surface includes an opening through which the fluid flowing through the second flow path enters and exits the case.   
     
     
         15 . The heat exchanger according to  claim 2 , wherein
 the case includes both side wall surfaces extending between the pair of walls and connecting a first wall surface facing the first corrugated surface and a second wall surface facing the second corrugated surface,   each of the sidewall surfaces includes a shoulder portion parallel to the flow direction, and   edges of the partition member on both sides parallel to the flow direction are attached to the shoulder portions of the both sidewall surfaces.   
     
     
         16 . The heat exchanger according to  claim 15 , wherein
 a filler adhering the partition member to the case is disposed between the edge and the shoulder portion.
