Heat exchanger

Abstract

The present disclosure relates to a heat exchanger that is characterized by including at least one collector and at least one tube, in which case the tube is installed in the collector by at least one seal disposed between the collector and the tube in such a manner that fluid connection is possible between the collector and the tube, wherein the tube includes at least one reinforcing element. The present disclosure also relates to a method of installing a heat exchanger and a method of manufacturing a heat exchanger, in which case at least one tube is installed in at least one collector by at least one seal disposed between the collector and the tube in such a manner that fluid connection is possible between the collector and the tube, wherein at least one reinforcing element is provided in or to the at least one tube.

1 . A heat exchanger, comprising at least one collector and at least one tube, in which the tube is installed in the collector by at least one seal disposed between the collector and the tube in such a manner that fluid connection is possible between the collector and the tube, wherein the tube comprises at least one reinforcing element that is provided only in a connection region between the tube and the collector. 
     
     
         2 . The heat exchanger according to  claim 1 , wherein the at least one tube is flat and has a relatively long axis, when viewed in cross-section, the length of which is 12 mm or more and/or up to 100 mm. 
     
     
         3 . The heat exchanger according to  claim 2 , wherein the at least one reinforcing element is basically an inner rib extending perpendicular to the long axis and/or basically a tube wall extending perpendicular to a tube axis. 
     
     
         4 . The heat exchanger according to  claim 1 , wherein the at least one reinforcing element is an insert. 
     
     
         5 . The heat exchanger according to  claim 4 , wherein the at least one insert has at least one step and/or at least one web and/or a circular or elliptical cross-section. 
     
     
         6 . The heat exchanger according to  claim 1 , wherein the at least one reinforcing element is a collar provided on a tube end. 
     
     
         7 . The heat exchanger according to  claim 1 , wherein the at least one reinforcing element is soldered to the tube. 
     
     
         8 . A method of manufacturing a heat exchanger by installing at least one tube in at least one collector by means of a seal disposed between the collector and the tube in such a manner that fluid connection is possible between the collector and the tube, wherein at least one reinforcing element is provided in or to the at least one tube. 
     
     
         9 . The method according to  claim 8 , wherein at least one inner rib is formed integrally (= in a manner that is built in) with the tube. 
     
     
         10 . The method according to  claim 8 , wherein the tube has a flat cross-section with a relatively long axis and a relatively short axis when viewed in cross-section and at least one wall of the tube is basically bent in a manner extending perpendicular to the tube axis. 
     
     
         11 . The method according to  claim 8 , wherein the at least one reinforcing element is soldered to the at least one tube. 
     
     
         12 . The method according to  claim 11 , wherein the at least one reinforcing element is soldered to the tube either before or after the tube is installed in the collector or together during installation of the tube. 
     
     
         13 . The method according to  claim 8 , wherein the at least one reinforcing element is formed by extrusion molding and/or bending.
