A thermoelectric cooler (TEC) with attached heat sinks centrally positioned at the discharge of a blower and in turn mounted in an enclosure to provide a supply of cooled air to the driver or passenger of a vehicle. A blower/motor assembly produces a steady flow of air, a fraction of which is directed over the hot side of the TEC where it removes heat with the aid of a high efficiency heat sink disposed within the air stream. This air is exhausted to the ambient, away from the person. The remaining fraction of air discharged from the blower is directed to the cold side of the TEC where it is cooled with the aid of a high efficiency heat sink. The cooled air exits the enclosure and is blown on the head and face of the person for the purpose of cooling and personal comfort. Power is provided by a jack that is to be inserted in a cigarette lighter socket. A clip is operable to mount said enclosure to the sun shade of a vehicle in close proximity to the persons head and face where greatest efficiency and cooling effect is achieved.
