Der Vorzug dieser Bauform liegt in Verbindung mit dem dafür insbesondere eingesetzten Herstellungsverfahren (Spritzgießen von Thermoplasten, Tiefziehen von thermoplastischen Folien und Laserschweißen) in den möglichen geometrischen Freiheitsgraden sowie der Gestaltung des Wärmetauschers.The advantage of this design in connection with the manufacturing process used for this (injection molding of thermoplastics, deep drawing of thermoplastic foils and laser welding) lies in the possible geometrical degrees of freedom as well as the design of the heat exchanger.
In einer bevorzugten Ausfuhrungsform verläuft der Kanal mäandrierend auf der Ober- und/oder Unterseite des Grundkörpers.In a preferred embodiment, the channel runs meandering on the top and / or bottom of the base body.
In einer ebenfalls bevorzugten Ausführungsform hat der Kanal eine Querschnittsfläche, insbesondere bei Verwendung von flüssigen Medien, von 1 bis 200 mm2 und, insbesondere bei gasförmigen Medien von 1 bis 500 mm2.In a likewise preferred embodiment, the channel has a cross-sectional area, in particular when using liquid media, from 1 to 200 mm 2 and, in particular with gaseous media, from 1 to 500 mm 2 .

Auslassstatzen mit dem Grundkörper vorzugsweise einstückig verbunden. Eine besonders bevorzugte Ausfuhrungsform besteht aus einer Kombination des Wärmetauschers mit einem Kfz-Formteil z.B. einem Luftsammler eines Kfz-Motors, welches in Schalentechnik aus thermoplastischem Kunststoff (PA 66) hergestellt wird. Auf der Innenseite des Formteiles werden entsprechend mäandrierende Kanalsegmente geformt. Durch Laserschweißen wird eine strömungsgünstig geformte Folie aufgeschweißt. Die Anschlüsse des Wärmetauschers sind an der Außenseite des Formteiles mitangeforrnt. Dadurch entsteht ein in den Luftsammler des Saugrohres integrierter Wärmetauscher, welcher der strömungsgünstigen dreidimensionalen Formgebung des Saugrohres angepasst ist. Die besondere Kühlleistung entsteht in diesem Fall durch die mit hoher Geschwindigkeit an der Wärmetauscheroberfläche vorbeistreifende Frischluft der Motoransaugung. Die dadurch gewonnene Kühlleistung kann zur Kühlung der Motorsteuerelektronik eingesetzt werden (Gehäuse der Elektronik ist mit dem gleichen Segment ausgestattet).Outlet pegs are preferably connected in one piece to the base body. A particularly preferred embodiment consists of a combination of the heat exchanger with a motor vehicle molded part, for example an air collector of a motor vehicle, which is produced using shell technology from thermoplastic material (PA 66). Correspondingly meandering channel segments are formed on the inside of the molded part. A streamlined film is welded on by laser welding. The connections of the heat exchanger are also provided on the outside of the molded part. This creates a heat exchanger integrated in the air collector of the intake manifold, which is adapted to the aerodynamic three-dimensional shape of the intake manifold.
