Abstract
A device for temperature control for a motor vehicle, includes a diffractive optical element disposed on a surface of the motor vehicle, and a radiator. The diffractive optical element couples in incident radiation and conducts the coupled-in incident radiation away from an area of the motor vehicle to be cooled. The radiator includes an absorber to absorb the coupled-in incident radiation which is conducted to the absorber from the diffractive optical element. The radiator releases energy based on the coupled-in incident radiation absorbed by the absorber.
