Abstract

Frontscheinwerfer (10) für ein Kraftfahrzeug, mit wenigstens einer zu kühlenden Wärmequelle (20) und einer Kühleinrichtung (50), die einen thermisch mit der Wärmequelle (20) gekoppelten Kühlkörper sowie ein Gebläse mit einem Gebläsegehäuse aufweist, das einen den Kühlkörper kühlenden Luftstrom (40) erzeugt. Der Frontscheinwerfer (10) zeichnet sich dadurch aus, dass der Kühlkörper mit dem Gebläsegehäuse eine einstückige bauliche Kühlkörper-Gebläsegehäuse-Einheit (52; 53) bildet.

Figure imgaf001
A headlight (10) for a motor vehicle, comprising at least one heat source (20) to be cooled and a cooling device (50) having a heat sink thermally coupled to the heat source (20) and a blower housing having a blower housing cooling an air flow ( 40). The headlight (10) is characterized in that the heat sink with the blower housing forms an integral structural heat sink-blower housing unit (52; 53).
