Heat exchanger comprising an integrated supply and discharge

Abstract

A heat exchanger, with a core region having a plurality of tube bundles through which a fluid flows in series is provided with at least one specially designed header composed of two half shells. The specially designed header deflects the fluid stream between two successive tube bundles in opposite directions, with the supply and discharge of the fluid to and from the core region through the header. The resulting heat exchanger is structurally simple, having a minimum number of components to be mounted.

1 - 14 . (canceled)  
     
     
         15 . A heat exchanger for a fluid, comprising: 
 a core region with at least two tube bundles of tubes arranged in parallel, through which the fluid flows;    collecting container headers arranged on end faces of the core region and open to end faces of the tubes,    a supply for supplying the fluid into the core region;    a discharge for discharging fluid out of the core region; and    wherein 
 the headers include transverse partitions which delimit regions of the headers through which the at least two tube bundles are fluidly connected in series, and  
 at least one header has a longitudinal partition which subdivides the header into a first region open to the tubes and a second region which is a tube bundle bypass.  
   
     
     
         16 . The heat exchanger as claimed in  claim 15 , wherein a block screw connection containing the supply and the discharge is arranged at one end of one of the headers.  
     
     
         17 . The heat exchanger as claimed in  claim 16 , wherein the longitudinal partition of the header has at least two passage orifices.  
     
     
         18 . The heat exchanger as claimed in  claim 17 , wherein a connection between the second part region of the header and a tube bundle of the core region is formed by at least one of the passage orifices in the longitudinal partition and a connection of the second part region to the block screw connection is formed by another of the at least two passage orifices.  
     
     
         19 . The heat exchanger as claimed in  claim 16 , wherein the block screw connection is arranged fixedly on the header.  
     
     
         20 . The heat exchanger as claimed in  claim 15 , wherein the at least one header having a longitudinal partition is formed from an open half shell and a closed half shell.  
     
     
         21 . The heat exchanger as claimed in  claim 15 , wherein the second part region of the at least one header having a longitudinal partition faces away from the tubes, and is continuous over a length of the header.  
     
     
         22 . The heat exchanger as claimed in  claim 21 , wherein the second part region of the header is subdivided into at least two separate ducts for the routing of two independent fluid streams.  
     
     
         23 . The heat exchanger as claimed in  claim 22 , wherein the at least two ducts of the second part region are arranged in parallel.  
     
     
         24 . The heat exchanger as claimed in  claim 22 , wherein the second part region is formed as a closed half shell having two chambers.  
     
     
         25 . The heat exchanger as claimed in  claim 23 , wherein the second part region is formed as a closed half shell having two chambers.  
     
     
         26 . The heat exchanger as claimed in  claim 15 , wherein the headers are configured to be received in a corresponding guide rail for holding the heat exchanger.  
     
     
         27 . The heat exchanger as claimed in  claim 26 , wherein the heat exchanger is an air conditioning condenser.  
     
     
         28 . The heat exchanger as claimed in  claim 27 , wherein the air conditioning condenser has a supercooling stage.  
     
     
         29 . The heat exchanger as claimed in  claim 26 , wherein the heat exchanger is a gas cooler.
