Method for producing a heat exchanger and heat exchanger

Abstract

A process (or method) for manufacturing a heat exchanger includes inserting at least one plate for heat emission between two adjacent corrugations of a corrugated body. The corrugations are pressed against each other such that the inserted plate is clamped in between the corrugations in a positive-locking and non-positive manner. The heat exchanger for cooling fluids includes a tube, which is designed partially as a corrugated body and has at least one plate inserted for heat emission between two corrugations of the corrugated body.

1 . A method for manufacturing a heat exchanger for cooling fluids with a tube, the process comprising the steps of:
 designing the tube partially as a corrugated body;   inserting at least one plate for heat emission between two corrugations of the corrugated body; and   pressing the corrugations against each other such that the inserted plate is clamped in between the corrugations.   
     
     
         2 . A method in accordance with  claim 1 , wherein the corrugations are pressed radially uniformly against the plate by axial upsetting by means of a tool. 
     
     
         3 . A method in accordance with  claim 1 , wherein two plates are inserted between two adjacent corrugations from radially opposite sides of the tube before the pressing. 
     
     
         4 . A method in accordance with  claim 1 , wherein the plate is provided in advance with a semicircular recess fitting a diameter of a center of a radii of the tube in the corrugation valley. 
     
     
         5 . A heat exchanger for cooling exhaust gases, the heat exchanger comprising:
 a tube formed partially as a corrugated body; and   a plate inserted for heat emission between two corrugations of the corrugated body and clamped in between the two corrugations.   
     
     
         6 . A heat exchanger in accordance with  claim 5 , wherein the plate has a rectangular or semicircular shape. 
     
     
         7 . A heat exchanger in accordance with  claim 5 , wherein at an edge facing the tube, the plate has a semicircular or U-shaped recess fitting a diameter of the corrugated body in a corrugation valley. 
     
     
         8 . A heat exchanger in accordance with  claim 5 , further comprising another plate to provide two plates inserted between the two corrugations from radially opposite sides of the tube. 
     
     
         9 . A heat exchanger in accordance with  claim 5 , wherein a heat exchange area formed between corrugations and the plate can be varied by means of different corrugation heights. 
     
     
         10 . A heat exchanger in accordance with  claim 5 , wherein at least one of the plate and the tube is manufactured from stainless steel. 
     
     
         11 . A method in accordance with  claim 2 , wherein two plates are inserted between two adjacent corrugations from radially opposite sides of the tube before the pressing. 
     
     
         12 . A method in accordance with  claim 2 , wherein the plate is provided in advance with a semicircular recess fitting a diameter of the center of the radii of the tube in a corrugation valley. 
     
     
         13 . A method in accordance with  claim 3 , wherein the plates are provided in advance with a semicircular recess fitting a diameter of the center of the radii of the tube in a corrugation valley. 
     
     
         14 . A heat exchanger in accordance with  claim 6 , wherein at an edge facing the tube, the plate has a semicircular or U-shaped recess fitting a diameter of the corrugated body in a corrugation valley. 
     
     
         15 . A heat exchanger in accordance with  claim 7 , further comprising another plate to provide two plates inserted between the two corrugations from radially opposite sides of the tube. 
     
     
         16 . A heat exchanger in accordance with  claim 7 , wherein a heat exchange area formed between corrugations and the plate can be varied by means of different corrugation heights. 
     
     
         17 . A heat exchanger in accordance with  claim 8 , wherein a heat exchange area formed between corrugations and the plates can be varied by means of different corrugation heights. 
     
     
         18 . A heat exchanger in accordance with  claim 7 , wherein at least one of the plate and the tube is manufactured from stainless steel. 
     
     
         19 . A heat exchanger in accordance with  claim 8 , wherein at least one of the plates and the tube is manufactured from stainless steel. 
     
     
         20 . A heat exchanger in accordance with  claim 9 , wherein at least one of the plate and the tube is manufactured from stainless steel.
