Light source e.g. LED, cooling device for e.g. headlight of motor vehicle, has heat exchanger transferring heat from substrate to liquid to be circulated in windscreen washer circuit formed of orifice, ducts and closed heating circuit

摘要

The device has a heat exchange unit i.e. heat exchanger (13) for transferring heat from a substrate (14) to a liquid to be circulated in a liquid circuit i.e. windscreen washer liquid circuit, formed of orifice (7b), ducts (8b) and a closed heating circuit, of a motor vehicle. Wind-screen washer liquid reservoir (6) includes orifices for distributing the windscreen washing liquid on the headlights, wind-screen (P) and/or a rear window for cleaning. The closed heating circuit includes a circulation pump for forcing the circulation of the liquid in the pump.
