Abstract
A headlamp assembly for a motor vehicle having a light source, a chamber that receives the light source and a cooling channel for removing heat from the chamber. A conductive wall and an insulating wall cooperate to define the chamber and the channel. The conductive wall has a substantially higher thermal conductivity than the insulating wall to promote the heat exchange between the chamber and the cooling channel and to reduce heat exchange between the cooling channel and the relatively hot engine compartment.
Claims20
A headlamp assembly for a motor vehicle comprising:
- a lens;
- a conductive wall having a conductive wall inner surface and a conductive wall outer surface, the conductive wall inner surface cooperating with the lens to substantially define a chamber that is generally fluidly isolated from the atmosphere;
- a light source located within the chamber;
- and
- an insulating wall located outside of the chamber and having an insulating wall inner surface spaced apart from the conductive wall outer surface and cooperating to define a cooling channel therebetween to promote heat exchange between the chamber and the cooling channel, the cooling channel extending between an inlet and an outlet in fluid communication with the atmosphere;
- wherein the conductive wall has a thermal conductivity that is substantially higher than that of the insulating wall to promote the heat exchange between the chamber and the cooling channel.
