High capacity thermoelectric temperature control systems

A thermoelectric system comprising:

• a plurality of thermoelectric modules;
• and
• a plurality of heat transfer devices, each heat transfer device comprising a housing and one or more heat exchanger elements inside the housing, each heat transfer device accepting a working fluid to flow therethrough, at least some of the heat transfer devices in thermal communication with and sandwiched between at least two thermoelectric modules of the plurality of thermoelectric modules so as to form a stack of alternating thermoelectric modules and heat transfer devices arranged to provide thermal isolation along a direction of a working medium movement.
