Heat Exchange Device

Abstract

Heat exchange device with a plate element ( 1 ) which has a shaped part ( 5 ) which extends over a heat exchange surface, is of at least partly flexible design and forms a partial boundary of a cavity ( 13 ), through which a heat transfer medium can flow and which is tightly closed off on the base side by a web ( 11 ) which forms on the heat exchange surface the contact surface for the heat transfer to a body ( 3 ), against which body the plate element ( 1 ) can be placed, wherein a flexible retaining plate ( 21 ) for pressing the plate element ( 1 ) against the body ( 3 ) rests on that top side of the shaped part ( 5 ) which is remote from the heat exchange surface on the base side, and wherein the flexibility of retaining plate ( 21 ) and the deformability of shaped part ( 5 ) and web ( 11 ) on the base side are selected in such a way that the plate element ( 1 ) can be adapted to the geometry of the body ( 3 ).

1 . A heat exchange device having a plate element ( 1 ) which has a shaped part ( 15 ) which is at least partially designed to be flexible, which extends over the heat exchange surface, and which forms the partial boundary of a cavity ( 13 ) through which a heat transfer medium can flow and which is sealed tight on the bottom by a web ( 11 ) which on the heat exchange surface forms the contact surface for heat transfer with the body ( 3 ) against which the plate element ( 1 ) can be placed, resting on the top of the shaped part ( 5 ) which faces away from the bottom-side heat exchange surface, there being a flexible retaining plate ( 21 ) for pressing the plate element ( 1 ) against the body ( 3 ) and the flexibility of the retaining plate ( 21 ) and the deformability of the shaped part ( 5 ) and bottom-side web ( 11 ) being chosen such that the plate element ( 1 ) can be adapted to the geometry of the body ( 3 ). 
   
   
       2 . The heat exchange device according to  claim 1 , wherein the shaped part ( 5 ) can be formed from an elastomer, preferably from nitrile rubber NBR. 
   
   
       3 . The heat exchange device according to  claim 1 , wherein the bottom-side web ( 11 ) is formed by a film which has been made thin compared to the wall thickness of the shaped part ( 5 ), preferably from nitrile rubber NBR. 
   
   
       4 . The heat exchange device according to  claim 1 , wherein the retaining plate ( 21 ) is formed by a thin metal plate. 
   
   
       5 . The heat exchange device according to  claim 4 , wherein the heat exchange surface has a rectangular outline which is rounded on the corner regions and wherein the retaining plate ( 21 ) extends superficially over the entire heat exchange surface while exposing openings ( 23 ) in the access regions for supply and discharge of the heat transfer medium. 
   
   
       6 . The heat exchange device according to  claim 1 , wherein the shaped part forms a plate ( 5 ) with a planar sealing edge ( 9 ) which extends continuously along the outside edge of the heat exchange surface and to which the bottom-side web ( 11 ) is attached with the formation of a seal, and wherein the plate ( 5 ) in the region within the sealing edge runs offset away from the bottom-side web ( 11 ) in order to form the inner cavity ( 13 ) between the plate ( 5 ) and the bottom-side web ( 11 ). 
   
   
       7 . The heat exchange device according to  claim 6 , wherein on the side of the plate ( 5 ) facing the web ( 11 ) there are burls ( 15 ) projecting into the cavity ( 13 ) as spacers between the bottom-side web ( 11 ) and the plate ( 5 ) and for producing turbulence of the flow of the heat transfer medium. 
   
   
       8 . The heat exchange device according to  claim 7 , wherein the plate ( 5 ) has connecting branches ( 19 ) which are molded to the top for supply and discharge of heat medium into and out of the cavity and which penetrate the openings ( 23 ) which are made in the retaining plate ( 21 ) which adjoins on the top. 
   
   
       9 . The heat exchange device according to  claim 8 , wherein the plate ( 5 ) on its top in the region ( 7 ) above the cavity ( 13 ) forms a planar contact surface for the retaining plate ( 21 ), and on the sealing edge ( 9 ) which extends along the outside of the heat exchange surface has at least one bead ( 29 ,  31 ) which projects on the top and which extends peripherally along the edge to increase the contact forces which are applied by the retaining plate ( 21 ) and which act on the sealing edge ( 9 ). 
   
   
       10 . The heat exchange device according to  claim 3 , wherein the film provided as the bottom-side web ( 11 ) is connected by cementing to the sealing edge ( 9 ) of the shaped part ( 5 ).
