TEMPERING DEVICE FOR A FUEL SUPPLY SYSTEM OF A MOTOR VEHICLE

The invention relates to a temperature control device for a fuel supply system of a motor vehicle, in particular a commercial vehicle, as well as a motor vehicle equipped with such a temperature control device. The temperature control device (1) comprises a fuel inlet (2), a fuel outlet (3) and a first temperature control section (5) between fuel inlet (2) and fuel outlet (3), which is thermally coupled to a Peltier device (7). The temperature control device (1) further comprises a second temperature control section (9) between fuel inlet (2) and fuel outlet (3), which is thermally coupled to a cooling circuit (11) of an internal combustion engine of the motor vehicle, as well as a switchable control valve (12) which is connected on the inlet side to the fuel inlet (2) and which connects the fuel inlet (2) in a first switching position to the first temperature control section (5) and in a second switching position to the second temperature control section (9).
