Heat exchanger

Abstract

The aim of the invention is to provide a light and especially simple heat exchanger comprising a number of parallel, interspaced flat tubes. To this end, the flat tubes ( 2 ) can be supplied with a fluid (F) via at least one end ( 8 ) by means of a manifold ( 6 ), said flat tubes ( 2 ) being arranged in the manifold ( 6 ) in an at least partially positively locking manner.

1 . A heat exchanger ( 1 ) having a number of flat tubes ( 2 ) which are arranged parallel to and at a distance from one another and via at least one end ( 8 ) can be fed with a fluid (F) via a collection manifold ( 6 ), the flat tubes ( 2 ) being arranged at least partially in a positively locking manner in the collection manifold ( 6 ).  
   
   
       2 . The heat exchanger as claimed in  claim 1 , in which an outer contour ( 10 ), which represents the end ( 8 ) of the respective flat tube ( 2 ), is at least partially matched to an internal contour ( 12 ) which represents the collection manifold ( 6 ).  
   
   
       3 . The heat exchanger as claimed in  claim 1 , in which an outer contour ( 10 ), which represents the end ( 8 ) of the respective flat tube ( 2 ), is at least partially matched to an external contour ( 10 ) which represents the collection manifold ( 6 ).  
   
   
       4 . The heat exchanger as claimed in  claim 1 , in which the end ( 8 ) of at least one of the flat tubes ( 2 ) is provided with one or more openings ( 13 ).  
   
   
       5 . The heat exchanger as claimed in  claim 1 , in which the end ( 8 ) of at least one of the flat tubes ( 2 ) has an open contour or opening.  
   
   
       6 . The heat exchanger as claimed in  claim 1 , in which the end ( 8 ) of at least one of the flat tubes ( 2 ) is provided with webs ( 20 ) on the outer side.  
   
   
       7 . The heat exchanger as claimed in  claim 1 , in which the end ( 8 ) of at least one of the flat tubes ( 2 ) is provided with a further, centrally arranged web ( 20 ).  
   
   
       8 . The heat exchanger as claimed in  claim 2 , in which the end ( 8 ) of the respective flat tube ( 2 ) is at least partially routed in a recess ( 14 ) which runs inside the internal contour ( 12 ).  
   
   
       9 . The heat exchanger as claimed in  claim 1 , in which the end ( 8 ) of the respective flat tube ( 2 ) is held in a positively locking manner at the collection manifold ( 6 ).  
   
   
       10 . The heat exchanger as claimed in  claim 8 , in which the end ( 8 ) of the respective flat tube ( 2 ) is soldered along the recess ( 14 ) of the collection manifold ( 6 ).  
   
   
       11 . The heat exchanger as claimed in  claim 1 , in which the collection manifold ( 6 ) is provided with at least one cutout ( 24 ) or a recess ( 14 ) for one of the flat tubes ( 2 ) to pass through.  
   
   
       12 . The heat exchanger as claimed in  claim 11 , in which the end ( 8 ) of the flat tube ( 2 ) in question is held cohesively at the cutout ( 24 ) of the collection manifold ( 6 ).  
   
   
       13 . The heat exchanger as claimed in  claim 1 , in which the collection manifold ( 6 ) is longitudinally and/or transversely divided into at least two regions ( 16 ).  
   
   
       14 . The heat exchanger as claimed in  claim 1 , in which the end ( 8 ) of at least one of the flat tubes ( 2 ) is provided with a slot ( 34 ) for receiving a partition wall ( 26 ).  
   
   
       15 . The heat exchanger as claimed in  claim 14 , in which the partition wall ( 26 ) has a through-opening ( 32 ).  
   
   
       16 . The heat exchanger as claimed in  claim 1 , in which the flat tubes ( 2 ) open out into an associated collection manifold ( 6 ) at each of the end sides.  
   
   
       17 . The heat exchanger as claimed in  claim 16 , in which the collection manifolds ( 6 ) arranged at the end sides of the flat tubes ( 2 ) are of identical design.  
   
   
       18 . The heat exchanger as claimed in  claim 1 , in which the flat tubes ( 2 ) arranged in a positively locking manner in the collection manifold ( 6 ) have differently designed ends ( 8 ).  
   
   
       19 . The heat exchanger as claimed in  claim 1 , in which at least one of the flat tubes ( 2 ) arranged in a positively locking manner in the collection manifold ( 6 ) is closed and acts as a partition wall.  
   
   
       20 . An air-conditioning system for a vehicle having a heat exchanger ( 1 ) as claimed in  claim 1.
