Heat exchanger

Abstract

The invention relates to a heat exchanger having a plurality of tubes ( 101 ) which are arranged in a parallel manner. Two tube parts ( 130 ) and ( 131 ) are arranged radially outside the tubes ( 101 ) in such a way that one part of the first part of the tube ( 130 ) is arranged radially outside one part of the second part of the tube ( 131 ) on one partial area of the axial extension of the heat exchanger. A sealing element ( 150 ) is also arranged in the area where both tube parts ( 130 ) and ( 131 ) extend over a partial area of the sealing element in the axial direction thereof in radial contact with each other.

       9 . The heat exchanger as claimed in  claim 1 , characterized in that the chamber is at least substantially sealed off by the ring-like elements.  
   
   
       10 . The heat exchanger as claimed in  claim 1 , characterized in that the chamber is not sealed off by the ring-like elements.  
   
   
       11 . The heat exchanger as claimed in  claim 1 , characterized in that the elements which protrude in the style of rings serve as a support, as seen in the radial direction, for the tube parts.  
   
   
       12 . The heat exchanger as claimed in  claim 1 , characterized in that the elements which protrude in the style of rings serve as axial bearings.  
   
   
       13 . The heat exchanger as claimed in  claim 1 , characterized in that the chamber is at least partially filled with an elastic means.  
   
   
       14 . The heat exchanger as claimed in  claim 11 , characterized in that the chamber is filled in such a manner that a ring-like element is formed from the elastic medium in the chamber, which extends between the radially inner tube part and the radially outer tube part.  
   
   
       15 . The heat exchanger as claimed in  claim 1 , characterized in that the elastic element can be laid into the chamber as a ring element.  
   
   
       16 . The heat exchanger as claimed in  claim 1 , characterized in that the elastic element can be introduced into the chamber as a pasty or gel-like medium.  
   
   
       17 . The heat exchanger as claimed in  claim 1 , characterized in that a plurality of tubes through which a first medium flows are arranged substantially parallel to one another radially inside the tube parts.  
   
   
       18 . The heat exchanger as claimed in  claim 1 , characterized in that the plurality of tubes are each connected, at their first end region, to a first terminating element and are each connected, at their second end region, to the second terminating element.  
   
   
       19 . The heat exchanger as claimed in  claim 1 , characterized in that the at least one tube through which a first medium flows is connected, at at least one end region, to a connection element for supplying and/or discharging a first medium.  
   
   
       20 . The heat exchanger as claimed in  claim 1 , characterized in that at least one terminating element is connected to at least one connection element for supplying and/or discharging a first medium.

       22 . The heat exchanger as claimed in  claim 1 , characterized in that the second medium flows around the tubes through which the first medium flows.
