Heat exchanger

Abstract

Disclosed is a heat exchanger comprising pipes and at least one receptacle ( 20 ). Said receptacle encompasses at least one pipe bottom ( 30 ) that is provided with passages ( 70 ), said passages ( 70 ) being surrounded by flanks ( 91 - 94 ).

1 . A heat exchanger having tubes and at least one header box, the header box comprising at least one tube plate, the tube plate having rims into which the tubes can be fitted, wherein the rims are enclosed by a respective peripheral flank, the flanks of two adjacent rims bordering each other with a bead being formed.  
   
   
       2 . The heat exchanger as claimed in  claim 1 , wherein the flanks each have an essentially constant width over the circumference of a rim.  
   
   
       3 . The heat exchanger as claimed in  claim 1 , wherein the tubes are flat tubes arranged in at least one row, in that the rims are of elongate design corresponding to the tube cross sections, and in that the flanks of the rims border one another with elongate beads being formed.  
   
   
       4 . The heat exchanger as claimed in  claim 1 , wherein the flanks each have a rounded portion with an approximately constant radius of curvature.  
   
   
       5 . The heat exchanger as claimed in  claim 4 , wherein the flanks each have a plurality of rounded portions with different radii of curvature.  
   
   
       6 . The heat exchanger as claimed in  claim 1 , wherein the flanks each have at least one planar region.  
   
   
       7 . The heat exchanger as claimed in  claim 6 , the at least one planar region forms an obtuse angle, in particular an angle of between 30° and 60°, with the respective rim.  
   
   
       8 . The heat exchanger as claimed in  claim 1 , wherein the rims face out of the at least one header box.  
   
   
       9 . A charge-air cooler, in particular for a motor vehicle, characterized by the features of  claim 1 .  
   
   
       10 . A method for producing a tube plate, comprising: 
 a) providing a planar metal sheet,    b) raising one or more edge regions of the planar metal sheet by means of a forming process,    c) placing depressions, which border one another, into the metal sheet by means of a forming process, the depressions each having an essentially planar base surface and a flank enclosing and encircling the base surface,    d) piercing the base surfaces by means of a draw-through process and, in particular, and    e) impressing introductory slopes therein in order to facilitate an introduction of tubes into the rims produced in step d).
