Abstract

Die vorliegende Erfindung betrifft eine elektrische Heizvorrichtung (2) mit einem Gehäuse (100), das eine Aufnahmetasche (102) ausbildet, in der zumindest eine PTC-Heizeinrichtung (2) mit zumindest einem in einem Positionsrahmen (10) aufgenommenen PTC-Element (4) und zur Bestromung des PTC-Elementes (4) mit unterschiedlicher Polarität mit diesem elektrisch leitend verbundene Leiterbahnen (6) aufgenommen ist. Die vorliegende Erfindung will eine elektrische Heizvorrichtung der eingangs genannten Art angeben, die in verbesserter Weise Fertigungstoleranzen ohne erhebliche Beeinträchtigung des Wärmeaustrags aus dem PTC-Element ausgleichen kann und sich wirtschaftlich herstellen lässt und schlägt hierzu vor, auf gegenüberliegenden Hauptseitenflächen des PTC-Elementes (4) jeweils zumindest ein Profilteil (26) wärmeleitend mit dem PTC-Element (4) zu verbinden, wobei dem PTC-Element (4) gegenüberliegende äußere Hauptseitenflächen der Profilteile (26) jeweils wärmeleitend mit einer Innenfläche (136) der Aufnahmetasche (102) verbunden sind und wobei die Profilteile (26) mit dem Positionsrahmen (10) verbunden sind.The present invention relates to an electrical heating device (2) with a housing (100) which forms a receiving pocket (102) in which at least one PTC heating device (2) with at least one PTC element (4 ) and for energizing the PTC element (4) with different polarity with this electrically conductively connected conductor tracks (6) is added. The present invention aims to provide an electrical heating device of the type mentioned at the outset, which can compensate for manufacturing tolerances in an improved manner without significantly impairing the heat discharge from the PTC element and can be produced economically, and for this purpose proposes on opposite main side surfaces of the PTC element (4) to connect at least one profile part (26) to the PTC element (4) in a thermally conductive manner, with the outer main side surfaces of the profile parts (26) opposite the PTC element (4) being thermally conductively connected to an inner surface (136) of the receiving pocket (102). and wherein the profile parts (26) are connected to the positioning frame (10).
