Abstract

Die vorliegende Erfindung betrifft eine Heizvorrichtung (10), aufweisend eine Zirkulationskammer (12) mit Ein- und Auslassöffnungen (14) für einen Wärmeträger (W), eine mit der Zirkulationskammer (12) wärmeleitend verbundene Heizeinrichtung (16) zum Erwärmen des Wärmeträgers (W) in der Zirkulationskammer (12), eine Anschlusskammer (20) mit einer darin angeordneten und eine Leiterplatte (24) umfassenden Steuerungseinrichtung (22) zur Steuerung der PTC-Heizeinrichtung (16), eine Trennwand (26) zwischen der Zirkulationskammer (12) und der Anschlusskammer (20), und einen auf der der Trennwand (26) abgewandten Seite der Steuerungseinrichtung (22) angeordneten Niederhalter (30), der mit der Steuerungseinrichtung (22) zusammenwirkt. Für einen verbesserten Schutz der elektrischen Heizvorrichtung (10) wird vorgeschlagen, dass der Niederhalter (30) Mittel zum Sammeln von Feuchtigkeit aufweist, die derart ausgebildet sind, dass auskondensierte Feuchtigkeit zumindest bereichsweise von der Steuerungseinrichtung abgehalten wird.The present invention relates to a heating device (10) having a circulation chamber (12) with inlet and outlet openings (14) for a heat transfer medium (W), a heating device (16) which is connected to the circulation chamber (12) in a heat-conducting manner for heating the heat transfer medium (W) in the circulation chamber (12), a connection chamber (20) with a control device (22) arranged therein and comprising a circuit board (24) for controlling the PTC heating device (16), a partition wall (26) between the circulation chamber (12) and the connection chamber (20), and a hold-down device (30) arranged on the side of the control device (22) facing away from the partition wall (26), which cooperates with the control device (22). For improved protection of the electric heating device (10), it is proposed that the hold-down device (30) has means for collecting moisture, which are designed such that condensed moisture is kept away from the control device at least in some areas.
