Container and Tool for Fixing a Connection

Abstract

The invention relates to a container, in particular a collection chamber of a heat exchanger, comprising an opening ( 2 ), in which a connection ( 5 ) is mounted. To simplify the installation of the connection, the latter ( 5 ) has a deformable connection edge region ( 10 ) on the edge facing the container ( 1 ), said edge region protruding into the container ( 1 ) prior to the deformation process and after the deformation lying at least partially against the interior of the container opening ( 2 ).

1 . A container, in particular a header of a heat exchanger, with an orifice in which a connection piece is mounted, wherein the connection piece has, at its end facing the container, a deformable connection piece edge region which, before deformation, projects into the container and, after deformation, bears at least partially against the container orifice on the inside.  
     
     
         2 . The container as claimed in  claim 1 , wherein the deformable connection piece edge region is connected with a form fit to that edge region of the container which has the container orifice.  
     
     
         3 . The container as claimed in  claim 1 , wherein the deformable connection piece edge region has a projection which, before deformation, projects radially inward and, during deformation, is deformed radially outward.  
     
     
         4 . The container as claimed in  claim 3 , wherein the projection is delimited by a continuous slope.  
     
     
         5 . The container as claimed in  claim 4 , wherein the continuous slope runs at an angle of about 45 degrees with respect to the connection piece longitudinal axis.  
     
     
         6 . The container as claimed in  claim 1 , wherein, in the edge region of the container orifice, at least one deformed region is formed, into which a complementarily deformed region of the deformable connection piece edge region engages.  
     
     
         7 . The container as claimed in  claim 1 , wherein a collar is formed at that end of the connection piece which has the deformable connection piece edge region.  
     
     
         8 . The container as claimed in  claim 1 , wherein a continuous depression is formed radially on the outside between the collar and the deformable connection piece edge region.  
     
     
         9 . A tool for fixing a connection piece as claimed in  claim 1  in a container orifice, wherein the tool has at least one deformation element which can be moved out of an introduction position into a deformation end position.  
     
     
         10 . The container as claimed in  claim 9 , wherein the deformation element is guided in the tool.  
     
     
         11 . The tool as claimed in  claim 10 , wherein the guide path of the deformation element runs essentially transversely with respect to the connection piece longitudinal axis.  
     
     
         12 . The tool as claimed in  claim 10 , wherein the guide path of the deformation element runs from the inner space of the container obliquely outward.  
     
     
         13 . The tool as claimed in  claim 9 , wherein the deformation element cooperates with a ramp which can be moved in relation to the tool in the direction of the connection piece longitudinal axis.  
     
     
         14 . The tool as claimed in  claim 13 , wherein the ramp is formed on a frustoconical region which tapers outward.  
     
     
         15 . The tool as claimed in  claim 14 , wherein the frustoconical region can be actuated from outside.  
     
     
         16 . The container as claimed in  claim 14 , characterized in that wherein a connecting element extends outward from the frustoconical region.  
     
     
         17 . The tool as claimed in  claim 9 , wherein the deformation element has an essentially convex region toward the container orifice.  
     
     
         18 . The tool as claimed in  claim 17 , wherein, during deformation, the convex region comes to bear with its outwardly facing half against the deformable connection piece edge region.  
     
     
         19 . The tool as claimed in  claim 9 , wherein the deformation element is formed by a sphere.  
     
     
         20 . The tool as claimed in  9 , wherein the tool has a plurality of deformation elements which are distributed, uniformly spaced apart, over the circumference of the tool.
