Heat exchanger

Abstract

Heat exchanger ( 1 ) having a housing ( 9 ), having a first fluid port ( 6, 7 ) and having a second fluid port ( 7, 6 ), wherein the housing ( 9 ) is in fluid communication with a fluid source via the first fluid port ( 6, 7 ) and the second fluid port ( 7, 6 ) and can be traversed by a flow of a fluid, characterized in that the housing ( 9 ) is of multi-part design and is formed by a housing upper part ( 3 ) and a trough-like housing lower part ( 2 ), wherein the housing lower part ( 2 ) has a base region ( 7 ) and an at least partially encircling turned-up edge region ( 6 ), wherein the housing upper part ( 3 ) or the housing lower part ( 2 ) is formed from a plastic and the respective other housing part ( 3, 2 ) is formed from a plastic, a metallic material or a fiber composite material.

1 . Heat exchanger ( 1 ) having a housing ( 9 ), having a first fluid port ( 6 ,  7 ) and having a second fluid port ( 7 ,  6 ), wherein the housing ( 9 ) is in fluid communication with a fluid source via the first fluid port ( 6 ,  7 ) and the second fluid port ( 7 ,  6 ) and can be traversed by a flow of a fluid, characterized in that the housing ( 9 ) is of multi-part design and is formed by a housing upper part ( 3 ) and a trough-like housing lower part ( 2 ), wherein the housing lower part ( 2 ) has a base region ( 7 ) and an at least partially encircling turned-up edge region ( 6 ), wherein the housing upper part ( 3 ) or the housing lower part ( 2 ) is formed from a plastic and the respective other housing part ( 3 ,  2 ) is formed from a plastic, a metallic material or a fiber composite material. 
     
     
         2 . Heat exchanger ( 1 ) according to one of the preceding claims, characterized in that at least one flow-guiding element ( 4 ,  5 ) is arranged in the interior of the housing ( 9 ). 
     
     
         3 . Heat exchanger ( 1 ) according to one of the preceding claims, characterized in that the housing lower part ( 2 ) is formed from a plastic. 
     
     
         4 . Heat exchanger ( 1 ) according to one of the preceding claims, characterized in that the housing upper part ( 3 ) is formed from a metallic material, in particular from aluminum or an aluminum alloy. 
     
     
         5 . Heat exchanger ( 1 ) according to  claim 4 , characterized in that the flow-guiding elements ( 4 ) are in the form of webs or walls or studs, and form between them at least one flow duct for the fluid. 
     
     
         6 . Heat exchanger ( 1 ) according to one of the preceding claims, characterized in that the flow-guiding element ( 4 ) runs parallel to at least one of the turned-up edge regions of the housing lower part ( 2 ). 
     
     
         7 . Heat exchanger ( 1 ) according to one of the preceding claims, characterized in that the housing upper part ( 3 ) or the housing lower part ( 2 ) has the first fluid port ( 6 ,  7 ) and the second fluid inlet ( 7 ,  6 ), or in that the housing upper part ( 3 ) and the housing lower part ( 2 ) have in each case one of the two fluid ports ( 6 ,  7 ). 
     
     
         8 . Heat exchanger ( 1 ) according to one of the preceding claims, characterized in that the first fluid port and/or the second fluid port is formed by an opening on one of the turned-up edge regions of the housing lower part ( 2 ). 
     
     
         9 . Heat exchanger ( 1 ) according to one of the preceding claims, characterized in that the housing ( 9 ) has, in its interior, a partition ( 8 ) which divides the internal volume of the housing into a first chamber and a second chamber which are in fluid communication with one another via a break in the partition ( 8 ). 
     
     
         10 . Heat exchanger ( 1 ) according to  claim 9 , characterized in that one of the fluid ports ( 6 ,  7 ) is in fluid communication with the first chamber and the respective other fluid port ( 7 ,  6 ) is in fluid communication with the second chamber.
