Heat Exchanger

Abstract

The invention relates to a heat exchanger, particularly in tube bundle-type, panel-type or plate-type design. The heat exchanger has a housing inside of which a number of flow channels are formed for a primary flow and a secondary medium, and the housing has a sandwich design.

1 . A heat exchanger, in particular of a tube-bundle, plate or disk type of construction, the heat exchanger having a housing in which a plurality of flow passages for a primary medium and a secondary medium are formed, wherein the housing is formed, at least in regions, in particular so as be essentially continuous, with a sandwich type of construction.  
   
   
       2 . The heat exchanger as claimed in  claim 1 , wherein the housing of sandwich type of construction is formed by at least two plates, the outer surface of the outer plate forming the housing outer surface.  
   
   
       3 . The heat exchanger as claimed in  claim 1 , wherein the housing of sandwich type of construction is formed by at least two plates, the inner plate being at a distance from the outer plate forming the housing outer surface.  
   
   
       4 . The heat exchanger as claimed in  claim 1 , wherein the housing of sandwich type of construction comprises a rib structure formed by a central plate, this rib structure being arranged between an outer plate and an inner plate.  
   
   
       5 . The heat exchanger as claimed in  claim 4 , wherein the rib structure is brazed or welded in place between the outer plate and the inner plate.  
   
   
       6 . The heat exchanger as claimed in  claim 1 , wherein, in the housing of sandwich type of construction, a flow passage for one of the operating media is provided between an outer plate and an inner plate.  
   
   
       7 . The heat exchanger as claimed in  claim 1 , wherein, in the housing of sandwich type of construction, tube bundles, plates or disk stacks are arranged on the inside of an inner plate.  
   
   
       8 . The heat exchanger as claimed in  claim 1 , wherein the housing, at least in regions, has precisely two plates which are provided in particular with spacers such as ribs, webs, corrugations, studs or the like.  
   
   
       9 . The heat exchanger as claimed in  claim 1 , wherein the housing is formed in a sandwich type of construction in each case in housing regions arranged opposite one another, in particular in two housing regions.  
   
   
       10 . The use of a heat exchanger as claimed in  claim 1  as an exhaust-gas cooler, a charge-air/cooling-medium cooler or an oil cooler.
