Multi-stage electronic cooling device

A multi-stage electronic cooling device comprising:

• a plurality of electrically insulating base plates disposed in a layered arrangement;
• a plurality of thermoelectric converter portions having the Peltier effect and disposed between neighboring electrically insulating base plates of the plurality of electrically insulating base plates;
• a through hole formed in at least one electrically insulating base plate of the plurality of electrically insulating base plates, said at least one electrically insulating base plate carrying thermoelectric converter portions on opposite surfaces thereof, the opposite surfaces of the at least one electrically insulating base plate facing adjacent electrically insulating base plates;
• and
• an electrically conductive member interconnecting, through an interior of the through hole, neighboring thermoelectric converter portions disposed on the opposite surfaces of the electrically insulating base plate having the through hole.

A multi-stage electrically cooling device comprising:

• a first electrically insulating base plate;
• a second electrically insulating base plate;
• a third electrically insulating base plate;
• a first thermoelectric converter portion having the Peltier effect and disposed between the first electrically insulating base plate and the second electrically insulating base plate;
• a second thermoelectric converter portion having the Pettier effect and disposed between the second electrically insulating base plate and the third electrically insulating base plate;
• a through hole formed in the second electrically insulating base plate;
• and
• an electrically conductive member interconnecting the first thermoelectric converter portion and the second thermoelectric converter portion via an interior of the through hole.
