Durch die erfindungsgemäße Ausgestaltung ist die gezielte Beeinflussung der Anström- bzw. Durchströmbedingungen von Wärmetauschern möglich, was zu einer Effizienzsteigerung führt.Heat exchanger for a coolant circuit, wherein the heat exchanger has a coolant inlet, which opens into largely parallel cooling pipes, in which the coolant is ducted to a coolant outlet, wherein the cooling tubes define a Luftdurchströmungsbereich and wherein cooling fins are arranged between the cooling tubes, which are largely in Direction of a heat exchanger flowing through the cooling air are aligned and wherein in at least a first part of the Luftdurchströmungsbereiches the cooling fins have a greater distance from each other than in a second part of the air flow area. Due to the configuration of the invention, the targeted influencing of the inflow or Durchströmbedingungen of heat exchangers is possible, resulting in an increase in efficiency.

Die Erfindung betrifft einen Wärmetauscher mit den Merkmalen aus dem Oberbegriff des Patentanspruchs 1.The invention relates to a heat exchanger with the features of the preamble of patent claim 1.
Bisher bekannte Luft-Medium-Wärmetauscher, hier speziell Kühlmittelkühler, werden nach geltenden Industriestandards mit einer einheitlichen Rippendichte bei der Luftlamelle ausgerüstet. Ein Beispiel hierfür ist aus der deutschen Offenlegungsschrift
Aus der europäischen Patentanmeldung
Auch aus der amerikanischen Patentanmeldung US 2005/274501 A1 ist es ferner bekannt, die Rippenanzahl eines gattungsgemäßen Wärmetauschers in Strömungsrichtung der Kühlungsluft unterschiedlich dicht auszugestalten, um einen möglichst hohen Wirkungsgrad des Wärmetauschers zu erzielen.It is also known from United States Patent Application US 2005/274501 A1, the density of fins of a generic heat exchanger in the flow direction of the cooling air different density to design, in order to achieve the highest possible efficiency of the heat exchanger.
Aufgrund besonderer Bauraum- oder Einbaubedingungen, bzw. aus Strömungs-/Druckverlustgründen ist es bisher nicht möglich, die Luftverteilung innerhalb mehrerer verschalteter Wärmetauscher, z. B. einem Kühlmodul in einer Art zu beeinflussen, so dass eine Gleichverteilung oder auch, wenn gewünscht, eine Ungleichverteilung der Strömungsgeschwindigkeiten bzw. Druckverluste in z. B. den einzelnen Wärmetauschern stattfinden kann. Beispielhaft sei hier z. B. eine außermittige Anordnung eines Elektrolüfters an einem Wärmetauscher zu erwähnen.Due to special space or installation conditions, or for flow / pressure loss reasons, it is not yet possible, the air distribution within several interconnected heat exchanger, eg. B. a cooling module in a way to influence, so that a uniform distribution or, if desired, an unequal distribution of the flow velocities or pressure losses in z. B. the individual heat exchangers can take place. Exemplary here z. B. to mention an eccentric arrangement of an electric fan to a heat exchanger.
Aufgabe der vorliegenden Erfindung ist es daher, eine Maßnahme aufzuzeigen, mit der o. g. Nachteile vermieden werden.Object of the present invention is therefore to show a measure with the o. G. Disadvantages are avoided.
