Abstract
An electric heating module for heating up air streams, in particular for heating and ventilating seats, which at least one PTC heating element and at least one annular heat dissipation region which is adjacent to said PTC heating element, through which air can flow and which has thermally conductive lamellae which are arranged so as to run in a substantially radial manner and are operatively connected to the PTC heating element and are combined with said PTC heating element to form a module. The lamellae sit, by way of their radially inner portion, in a groove of a thermally conductive retaining ring, which groove is matched to the width of the radially inner portion of the lamellae.
Claims33
An electric heating module for heating airflow, comprising at least one PTC-heating element (4) and at least one adjacent annular heat dissipation region (16), through which air can flow, having heat-conducting lamellae (3) arranged essentially extending radially, which are effectively connected to the PTC-heating element (4) to form a module, the lamellae (3) have a radially inner section positioned in a groove (2), adjusted to a width of the radially inner sections of the lamellae (3), at a perimeter of a heat conducting retainer ring (1).
