Abstract
A multi-stage electronic cooling device has an electrically insulating base plate, a first thermoelectric converter portion having the Peltier effect and disposed on one surface of the electrically insulating base plate, and a second thermoelectric converter portion having the Peltier effect and disposed on another surface of the electrically insulating base plate. A through hole is formed in the electrically insulating base plate. An electrically conductive member interconnects the first thermoelectric converter portion and the second thermoelectric converter portion via an interior of the through hole. In an optional construction, the electrically conductive member is formed of an electrically conductive coating formed on the inner peripheral surface of the through hole, and the first and second thermoelectric converter portions are disposed between the electrically insulating base plate and two additional insulating base plates at opposite sides thereof
