Heat exchanger

Abstract

Heat exchanger having a first collecting box and having a second collecting box, having at least one tube arranged between the two collecting boxes, wherein a fluid inlet and a fluid outlet are provided which are arranged individually on in each case one of the collecting boxes or on a single one of the collecting boxes, wherein the tube is received at the ends in an opening in in each case one of the collecting boxes and is in fluid communication with the collecting boxes, wherein the opening is surrounded by an opening edge whose contour corresponds to the outer contour of the tube, and in that the opening is designed such that the opening cross section narrows toward the interior of the collecting box and the tube can be inserted, under preload at the circumference, into the opening.

1 . Heat exchanger having a first collecting box and having a second collecting box, having at least one tube arranged between the two collecting boxes, wherein a fluid inlet and a fluid outlet are provided which are arranged individually on in each case one of the collecting boxes or on a single one of the collecting boxes, wherein the tube is received at the ends in an opening in in each case one of the collecting boxes and is in fluid communication with the collecting boxes, wherein the opening is surrounded by an opening edge whose contour corresponds to the outer contour of the tube, and in the opening is designed such that the opening cross section narrows toward the interior of the collecting box and the tube can be inserted, under preload at the circumference, into the opening. 
     
     
         2 . Heat exchanger according to  claim 1 , wherein the tube is in the form of a flat tube. 
     
     
         3 . Heat exchanger according to  claim 1 , wherein the inner contour of the opening can be deformed as a result of the tube being pushed in. 
     
     
         4 . Heat exchanger according to  claim 1 , wherein, in the assembled state, a groove which is accessible from outside the collecting box is formed between the tube and the opening edge. 
     
     
         5 . Heat exchanger according to  claim 1 , wherein the tube and the collecting boxes can be adhesively bonded and/or welded and/or pressed together and/or insert-molded with one another. 
     
     
         6 . Heat exchanger according to  claim 1 , wherein at least one of the collecting boxes is of multi-part form and has a box opening, the latter being closable by means of a cover, and has a tube plate with at least one opening for receiving a tube wherein the box opening is arranged opposite the tube plate. 
     
     
         7 . Heat exchanger according to  claim 1 , wherein the heat exchanger has a multiplicity of tubes which run parallel to and spaced apart from one another. 
     
     
         8 . Heat exchanger according to  claim 7 , wherein the tubes lie in a common plane and/or lie offset with respect to one another in multiple planes. 
     
     
         9 . Heat exchanger ( 1 ) according to  claim 7 , wherein an areal panel is mounted onto the tubes, by means of which panel said tubes are connected to one another. 
     
     
         10 . Heat exchanger according to  claim 1 , wherein the fluid inlet and the fluid outlet are arranged on the same collecting box, wherein said collecting box has a partition which divides the internal volume of the collecting box into two chambers, and the fluid inlet is in fluid communication with one of the chambers and the fluid outlet is in fluid communication with the other chamber.
