Method For Connecting Components

Abstract

The invention relates to a method for the connecting of components, namely for the connecting of at least one pipe-shaped or rod-shaped component with a wall-type component, with the following steps: a) providing a wall-type component ( 11 ), whereby the wall-type component ( 11 ) comprises a sandwich-type structure of two plate-shaped or pipe-shaped elements ( 12, 13 ) with a layer ( 14 ) of an expandable foamable metal material positioned therebetween; b) providing at least one pipe-shaped or rod-shaped component ( 10 ); c) introducing at least one opening in the wall-type component ( 11 ) for the receiving of the or each pipe-shaped or rod-shaped component ( 10 ); d) inserting of the or each pipe-shaped or rod-shaped component ( 10 ) in a corresponding opening of the wall-type component ( 11 ); e) heating of the arrangement of the wall-type component ( 11 ) and the or each pipe-shaped or rod-shaped component ( 10 ) with foaming-up expansion of the expandable foamable metal material for the connecting of the or each pipe-shaped or rod-shaped component ( 10 ) with the wall-type component ( 11 ).

1 . Method for the connecting of components, namely for the connecting of at least one pipe-shaped or rod-shaped component with a wall-type component, with the following steps: 
 a) providing a wall-type component ( 11 ), whereby the wall-type component ( 11 ) comprises a sandwich-type structure of two plate-shaped or pipe-shaped elements ( 12 ,  13 ) with a layer ( 14 ) of an expandable foamable metal material positioned therebetween;    b) providing at least one pipe-shaped or rod-shaped component ( 10 );    c) introducing at least one opening into the wall-type component ( 11 ) for the receiving of the or each pipe-shaped or rod-shaped component ( 10 );    d) inserting the or each pipe-shaped or rod-shaped component ( 10 ) in a corresponding opening of the wall-type component ( 11 );    e) heating of the arrangement of the wall-type component ( 11 ) and the or each pipe-shaped or rod-shaped component ( 10 ) with foaming-up expansion of the expandable foamable metal material for the connecting of the or each pipe-shaped or rod-shaped component ( 10 ) with the wall-type component ( 11 ).    
   
   
       2 . Method according to  claim 1 , characterized in that the or each pipe-shaped or rod-shaped component ( 10 ) is coated with a solder ( 16 ) on a section or end ( 15 ) with which the same is inserted into the corresponding opening of the wall-type component ( 11 ).  
   
   
       3 - 9 . (canceled)  
   
   
       10 . Method according to  claim 1 , characterized in that the two plate-shaped or pipe-shaped elements ( 12 ,  13 ) of the wall-type component ( 11 ) are volume-stable during the heating and are not foamed-up.  
   
   
       11 . Method according to  claim 1 , characterized in that the layer ( 14 ) of the expandable foamable metal material positioned between the two plate-shaped or pipe-shaped elements ( 12 ,  13 ) is formed of a sintered metal powder and at least one propellant.  
   
   
       12 . Method according to  claim 11 , characterized in that the metal powder is formed on the basis of an aluminum alloy or titanium alloy or nickel alloy or cobalt alloy or iron alloy.  
   
   
       13 . Method according to  claim 11 , characterized in that the propellant is formed by titanium hydride.  
   
   
       14 . Method according to  claim 1 , characterized in that a section or an end ( 15 ) of the pipe-shaped component ( 10 ), with which the same is inserted in a corresponding opening of the wall-type component ( 11 ), is closed with a stopper-type element before the insertion of the pipe-shaped component ( 10 ) in the corresponding opening of the wall-type component ( 11 ) or before the heating and therewith foaming-up expansion, whereby the stopper-type element is removed out of the section or end ( 15 ) of the pipe-shaped component ( 10 ) after the foaming-up expansion.  
   
   
       15 . Method according to  claim 1 , characterized in that the foaming-up expansion is terminated by cooling upon reaching a defined degree of foaming.  
   
   
       16 . Method according to  claim 1 , characterized in that a cylinder-shaped flow pipe of a heat exchanger is provided as wall-type component ( 11 ), and that lance pipes of a heat exchanger are provided as pipe-shaped components ( 10 ), which are connected with the flow pipe.
