Collecting vat, heat exchanger and method for producing a collecting vat

Abstract

The invention relates to a collecting vat ( 1 ) comprising at least one tie rod ( 2 ) formed by a rivet, a screw or a bolt, the tractive forces thereof being at least partially absorbed by an element arranged inside the collecting vat ( 1 ).

1 . A collecting vat for a heat exchanger, with at least one tie rod ( 2 ), the collecting vat being composed in particular of plastic, characterized in that the tie rod ( 2 ) is formed by a rivet, a screw or a bolt.  
   
   
       2 . The collecting vat as claimed in  claim 1 , characterized in that the tie rod ( 2 ) is arranged in a hollow profile ( 3 ).  
   
   
       3 . The collecting vat as claimed in  claim 2 , characterized in that the hollow profile ( 3 ) is a tube or a hollow profile designed in the manner of a guide vane.  
   
   
       4 . The collecting vat as claimed in  claim 2 , characterized in that the collecting vat ( 1 ) is sealed off from the hollow profile ( 3 ).  
   
   
       5 . The collecting vat as claimed in  claim 1 , characterized in that a sealing element ( 4 ) is placed between collecting vat ( 1 ) and hollow profile ( 3 ) and/or collecting vat ( 1 ) and tie rod ( 2 ).  
   
   
       6 . The collecting vat as claimed in  claim 1 , characterized in that a washer ( 5 ) is provided on the outside of the collecting vat ( 1 ).  
   
   
       7 . The collecting vat as claimed in  claim 1 , characterized in that an inner thread is provided on one side of the collecting vat, in the interior thereof, and the tie rod is screwed into it.  
   
   
       8 . The collecting vat as claimed in  claim 2 , characterized in that the hollow profile ( 3 ) is under a compressive stress as a consequence of a tensile stress exerted continually by the tie rod ( 2 ).  
   
   
       9 . The collecting vat as claimed in  claim 1 , characterized in that the tie rod has at least one mount, in particular a screw thread, with a fastening means, in particular a screw, engaging from the outside into the mount through an opening in the collecting vat.  
   
   
       10 . A heat exchanger, in particular charge air cooler for a motor vehicle, with at least one collecting vat and heat exchanger tubes, the heat exchanger tubes communicating with the at least one collecting vat, characterized in that at least one collecting vat is designed as claimed in  claim 1 .  
   
   
       11 . A method for producing a collecting vat as claimed in  claim 1 , characterized in that, after the collecting vat ( 1 ) is finished, the tie rod ( 2 ) is introduced into the same and fixed in place, with an element for absorbing tensile forces of the tie rod ( 2 ) being provided in the collecting vat ( 1 ).  
   
   
       12 . The method as claimed in  claim 9 , characterized in that the tie rod ( 2 ) is guided through a hollow profile ( 3 ).  
   
   
       13 . The method as claimed in  claim 9 , characterized in that the element for absorbing tensile forces of the tie rod ( 2 ) is injected, placed or clamped into the collecting vat.  
   
   
       14 . The method as claimed in  claim 9 , characterized in that a respective sealing element ( 4 ) is fitted at at least one end of the element for absorbing tensile forces and/or at at least one end of the tie rod ( 2 ).
