Abstract

Bei einem Wärmeübertrager, insbesondere einem Abgaswärmeübertrager, mit einem zur Gasführung dienenden Rohrbündel (10) aus Rechteckrohren (19) und mit einem das Rohrbündel umgebenden, zur Führung eines flüssigen Kühlmittels dienenden Außenmantel, der mit einem Kühlmitteleintritt (17) und einem Kühlmittelaustritt (18) versehen ist, wird vorgesehen, daß die Rechteckrohre des Rohrbündels (10) mit nach außen gerichteten Vorsprüngen (22) versehen ist, die den Abstand benachbarter Rechteckrohre zueinander und zu der Innenwand des Außenmantels (11) bestimmen.

Figure 00000001
In the case of a heat exchanger, in particular an exhaust gas heat exchanger, with a tube bundle (10) made of rectangular tubes (19) for gas guidance and with an outer jacket surrounding the tube bundle for guiding a liquid coolant, which has a coolant inlet (17) and a coolant outlet (18) is provided, it is provided that the rectangular tubes of the tube bundle (10) are provided with outwardly directed projections (22) which determine the distance between adjacent rectangular tubes to each other and to the inner wall of the outer jacket (11).
