Heat exchanger has flat tubes on at least one of two narrow sides provided with heating wire in recess and fastened there
A heat exchanger consists of several parallel flat tubes (1) through which the heat-exchange medium flows. They are connected with their ends to common outward- and return-flow unions (3) flowed against on the outside by the second heat-exchange medium. To at least a part of the flat tubes are assig...

| description | A heat exchanger consists of several parallel flat tubes (1) through which the heat-exchange medium flows. They are connected with their ends to common outward- and return-flow unions (3) flowed against on the outside by the second heat-exchange medium. To at least a part of the flat tubes are assigned electrically driven heating elements as additional heating. The flat tubes on at least one of the two narrow sides are provided with a heating wire (9) laid in a recess (8) and fastened there. The heating wire is provided with an insulation (13). The recess consists of an open groove which runs the length of the flat tubes.
Bekannte Wärmeübertrager, die aus Flachrohren aufgebaut sind, werden, um eine Zusatzbeheizung zu ermöglichen, zumindest an den äußeren Rohren des Flachrohrbündels mit PTC-Heizelementen bestückt. Die Anbringung solcher PTC-Elemente auf den Außenflächen der Flachrohre ist aufwendig. DOLLAR A Es wird vorgeschlagen, die Flachrohre als Mehrkammerprofile auszubilden und mindestens eine der äußersten Kammern in der Form einer Einlegenut für einen isolierten Heizdraht auszubilden, deren Wände dann zur Befestigung des Heizdrahtes zusammengebogen werden. Die Herstellung solcher Wärmeübertrager ist einfach. Verwendung für Wärmeübertrager von Kraftfahrzeugen. |
