Abstract

A compact thermoelectric refrigeration drive assembly comprises at least one thermoelectric heat transfer device (Peltier Effect device) whose active surfaces are in contact with a respective one of a collector member and a transfer member. When operating, a dc current is applied to the heat transfer device to transfer heat from the collector member to the transfer member. This results in the collector member, which is intended to be located in an insulated chamber, being cooled and the transfer member, which is spaced away from the collector member, being heated. Waste heat is removed from the transfer member via a closed looped fluid cooling system, the transfer member forming at least a portion of one side of a vessel for the cooling fluid and thereby transferring heat to the fluid. The construction and design of the assembly advantageously results in a compact refrigerator drive assembly which can be employed in a variety of environments.
