A thermoelectric refrigeration unit in which the heat-sink plate and cold plate are separated by spacer blocks, and the space between the plates is filled with thermal insulation. A separator encloses the insulation and the space between the plates and has the fan and power supply mounted to it. A cover encloses the fan, power supply and heat-radiating fins and has openings for circulation of air. The separator and cover are fastened to the cold plate which serves as the base for the unit and as the means for mounting the unit in an insulated enclosure. In a modified embodiment, a shroud and fan assembly is mounted over the cold plate for circulating refrigerated air within the insulated enclosure.
