ABSTRACT:
A thermoelectric icebox conversion unit features a cold plate (22) which incorporates bosses (24) and radially extending heat-collecting fins (23), all diecast as one integral unit which avoids sharp corners and joints, thereby decreasing resistance to thermal conductivity. The cold plate serves as the base for the unit and as the means for mounting the unit in an insulated enclosure. Thermoelectric modules (25) are attached to bosses (24). Thermal insulation (32) retained by a separator (31) is enclosed in the space between a heat sink plate (26) and the cold plate. A fan (34) and power supply is mounted on the separator and is attached to the cold plate. A cover (35) encloses the fan, power supply and heat-radiating fins (27) and has openings for circulation of air. A second fan assembly (41) is mounted within the cold plate fins (23), and a baffle plate (42) with openings is placed over the fins and the fan for circulating refrigerated air past the fins (23) as well as within the insulated enclosure.
