Abstract
A headlight for a vehicle with a cooling device for a semiconductor illuminant, wherein the cooling device comprises a fluid circuit with an evaporator, on or in which the semiconductor illuminant is arranged and a cooling medium can be evaporated, and wherein the cooling device further comprises a condenser on or in which the cooling medium can be condensed. The cooling medium comprises a first coolant, which has a first lower evaporation temperature and the cooling medium comprises a second coolant, which has a second higher evaporation temperature.
Claims10
A headlight for a vehicle with a cooling device for a semiconductor illuminant, the cooling device comprising:
- a fluid circuit with an evaporator, on or in which the semiconductor illuminant is arranged and in which a cooling medium is evaporated;
- and
- a condenser in which the cooling medium is condensed,
- wherein the cooling medium comprises a first coolant having a first evaporation temperature and a second coolant having a second evaporation temperature, the first evaporation temperature being lower than the second evaporation temperature,
- wherein at least one of the first coolant or the second coolant has a perfluorinated chemical compound which is derived from an ethyl isopropyl ketone, and
- wherein the first coolant and the second coolant form a mixture.
