Abstract
Systems and apparatus for heating or cooling food to an appropriate temperature for service using a standard food service container, such as a chafing dish or food cart. A thermally conductive plate has a plurality of Peltier chips attached thereto to drive a temperature difference. The Peltier chips are in thermally conductive contact with a heat exchanger. A heat transfer liquid circulates through tubing in the heat exchanger and a separate radiator, perpetuating the temperature difference at the plate. The heat exchanger and radiator may be spaced apart by a gap. One or more fans may be placed to encourage airflow through the radiator. A coolant reservoir and pump may be included.
