ABSTRACT:
A device for maintaining the temperature of a body at a desired value comprises a thermo-electric heat pump sandwiched between a thermally conductive member and a heat sink. The heat sink is maintained at a substantially constant temperature above the ambient temperature by an electrical heating element. This arrangement reduces the effect of changes in ambient temperature and enables the heat pump to work across a substantially constant temperature differential.
