Abstract

Die Erfindung betrifft einen PTC-Heizer (1), der mindestens ein PTC-Element (2) aufweist, welches zwischen zwei Kontaktblechen (3; 13) angeordnet und mit denselben elektrisch leitend verbunden ist, wobei mindestens ein Kontaktblech (3; 13) auf der Seite des oder der PTC-Elemente (2) mindestens zwei unterschiedlich strukturierte und/oder erhabene Bereiche aufweist. The invention relates to a PTC heater (1) having at least one PTC element (2) interposed between two contact plates; is arranged and connected with the same electrically conductive, wherein at least one contact plate (3; 13) (3 13) or the side of the PTC elements (2) has at least two differently structured and / or raised areas. Die zwei unterschiedlich strukturierten und/oder erhabenen Bereiche liegen bevorzugt dem oder den PTC-Elementen (2) zumindest teilweise direkt gegenüber. The two differently structured and / or raised areas are preferably compared with at least partially directly to the or the PTC elements (2).
