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. |
