Heat Exchanger Comprising A Bundle Provided With Means Permitting The Limitation Of The Movements Of The Said Exchange Bundle In Relation To The Walls Of The Housing

Abstract

A heat exchanger comprises a housing adapted to surround a heat exchange bundle. The housing is provided with an opening for receiving the heat exchange bundle in the interior of the housing. The heat exchange bundle comprises a first extremity adapted to close the opening in the housing when the heat exchange bundle is inserted in the interior of the housing. A second extremity of the heat exchange bundle opposite the first extremity is provided with at least one protuberance, and the wall of the housing is provided with a contact element adapted to support the protuberance in order to limit the movement of the second extremity of the heat exchange bundle in relation to the wall of the housing.

1 . A heat exchanger ( 1 ) comprising a housing ( 3 ) adapted to enclose a heat exchange bundle ( 4 ), the housing ( 3 ) being provided with an opening for receiving the heat exchange bundle ( 4 ) in the interior of the housing ( 3 ), the heat exchange bundle ( 4 ) comprising a first extremity adapted to close the opening in the housing ( 3 ) when the heat exchange bundle ( 4 ) is inserted into the interior of the housing ( 3 ), wherein a second extremity of the heat exchange bundle ( 4 ) opposite the first extremity is provided with at least one protuberance ( 21 ), and in which the wall ( 31 ) of the housing ( 3 ) is provided with a contact element ( 50 ) adapted to support the protuberance ( 21 ) in order to limit the movement of the second extremity of the heat exchange bundle ( 4 ) in relation to the wall ( 31 ) of the housing ( 3 ). 
     
     
         2 . A heat exchanger ( 1 ) according to  claim 1 , in which the heat exchange bundle ( 4 ) is introduced into the interior of the housing ( 3 ) in a direction of introduction, the protuberance ( 21 ) extends essentially in the direction of introduction, and the contact element ( 50 ) is adapted to support the protuberance ( 21 ) in order to limit the movement of the protuberance in relation to the wall ( 31 ) of the housing ( 3 ) in a direction essentially perpendicular to the direction of introduction. 
     
     
         3 . A heat exchanger ( 1 ) according to  claim 1 , in which the wall ( 31 ) of the housing ( 3 ) is provided with an opening allowing the protuberance ( 21 ) to pass through the wall ( 31 ) of the housing ( 3 ). 
     
     
         4 . A heat exchanger ( 1 ) according to  claim 1 , in which the contact element ( 50 ) is adapted to be secured to the exterior of the wall ( 31 ) of the housing ( 3 ) in order to support the protuberance ( 21 ) and to cover the opening. 
     
     
         5 . A heat exchanger ( 1 ) according to  claim 1 , in which the protuberance ( 21 ) is in the form of a peg. 
     
     
         6 . A heat exchanger ( 1 ) according to  claim 1 , in which the contact element ( 50 ) is in the form of a cap. 
     
     
         7 . A heat exchanger ( 1 ) according to  claim 1 , in which the heat exchange bundle ( 4 ) comprises an assembly of plates together with corrugated spacer elements, in which the plates and the corrugated spacer elements and the at least one protuberance ( 21 ,  22 ,  23 ) are assembled by means of a brazing process. 
     
     
         8 . A heat exchanger ( 1 ) according to  claim 2 , in which the wall ( 31 ) of the housing ( 3 ) is provided with an opening allowing the protuberance ( 21 ) to pass through the wall ( 31 ) of the housing ( 3 ). 
     
     
         9 . A heat exchanger ( 1 ) according to  claim 2 , in which the contact element ( 50 ) is adapted to be secured to the exterior of the wall ( 31 ) of the housing ( 3 ) in order to support the protuberance ( 21 ) and to cover the opening. 
     
     
         10 . A heat exchanger ( 1 ) according to  claim 3 , in which the contact element ( 50 ) is adapted to be secured to the exterior of the wall ( 31 ) of the housing ( 3 ) in order to support the protuberance ( 21 ) and to cover the opening.
