A defroster and a vehicle are provided. The defroster includes: a housing defining an air outlet; a heating device disposed in the housing; an air blower defining a blowing outlet and disposed in the housing; and an air duct defining a duct inlet and a duct outlet, the air duct being disposed between the blowing outlet and the heating device so that air blown out from the blower outlet enters the air duct via the duct inlet and goes out of the air duct via the duct outlet, then passes through the heating device to exchange heat with the heating device, and is discharged out of the housing via the air outlet, wherein an area of the duct inlet is different from that of the duct outlet.

Die vorliegende Erfindung betrifft ein PTC-Heizelement (2) mit zumindest einem PTC-Element (4), das zwischen Leiterbahnen (6) vorgesehen ist. Zur Verminderung der Luft- und Kriechstrecke zwischen den beiden Leiterbahnen (6) wird mit der vorliegenden Erfindung eine zumindest eine der Leiterbahnen (6) und/oder das PTC-Element (4) vollumfänglich einsiegelnde isolierende Masse (10) vorgeschlagen. Bei der erfindungsgemäßen elektrischen Heizvorrichtung liegt ein solches PTC-Heizelement an Wärme abgebenden Flächen der Heizvorrichtung elektrisch leitend an. Nach dem erfindungsgemäßen Verfahren zur Herstellung einer elektrischen Heizvorrichtung werden die Leiterbahnen (6) mit dem PTC-Element (4) zur Erzeugung einer PTC-Heizzelle (7) verklebt. Danach wird die PTC-Heizzelle (7) zwischen zwei elektrischen Isolierschichten durch eine umfänglich um zumindest eine der Leiterbahnen (6) und/oder das PTC-Element (4) aufgetragene isolierende Masse (10) eingesiegelt.
