Title (EN) ANNULAR HEATING ELEMENT
(FR) ÉLÉMENT CHAUFFANT ANNULAIRE
(DE) RINGFÖRMIGES HEIZELEMENT
Abstract:
(EN) The invention relates to a heating element with an annular housing in which a PTC heating resistor (13) and a contact element (14, 15) are arranged. According to the invention, the housing has an annular sheet metal part (11) which forms a radially inner wall (11d), a radially outer wall (11e), and a first end-face wall (11c). A respective sheet metal section (11a, 11b) adjoins both the radially inner wall (11d) as well as the radially outer wall (11e), said sheet metal section forming at least one part of a second end-face wall that lies opposite the first end-face wall (11c).
(FR) L’invention concerne un élément chauffant comportant un boîtier annulaire dans lequel sont disposés une résistance chauffante CTP (13) et un élément de contact (14, 15). Selon l’invention, le boîtier présente un élément en tôle annulaire (11) qui forme une paroi radialement interne (11d), une paroi radialement externe (11e) et une première paroi frontale (11c). Respectivement une partie en tôle (11a, 11b) est adjacente aussi bien à la paroi radialement interne (11d) qu’à la paroi radialement externe (11e) , ladite partie en tôle formant au moins une partie d’une deuxième paroi frontale du boîtier qui est opposée à la première paroi frontale (11c).
(DE) Beschrieben wird ein Heizelement mit einem ringförmigen Gehäuse, in dem ein PTC-Heizwiderstand (13) und ein Kontaktelement (14, 15) angeordnet sind. Erfindungsgemäß ist vorgesehen, dass das Gehäuse ein ringförmiges Blechteil (11) aufweist, das eine radial innere Wand (11d), eine radial äußere Wand (11e) und eine erste stirnseitige Wand (11c) bildet, wobei sowohl an die radial innere Wand (11d) als auch an die radial äußere Wand (11e) jeweils ein Blechabschnitt (11a, 11b) angrenzt, der zumindest einen Teil einer zweiten stirnseitigen Wand des Gehäuses, die der ersten stirnseitigen Wand (11c) gegenüberliegt, bildet.
