Abstract
An improved thermoelectric temperature control system for selectively heating or cooling a temperature control fluid to be provided through an exit conduit to an external thermal load and returned to the system through an inlet conduit. The system having at least a first liquid heat exchanger, a thermoelectric module in thermal conductivity with the liquid heat exchanger, a heat sink in thermal conductivity with the thermoelectric module, a pump and connecting conduits to move the temperature control fluid from the inlet conduit through the pump and liquid heat exchanger to the exit conduit and power and control electronics to activate the pump and thermoelectric module. The improvement comprises a thermal capacitor connected for fluid communication with the external thermal load and the thermoelectric temperature control system to provide thermal wattage to the external thermal load via the temperature control fluid in addition to the thermal wattage provided to the external thermal load by the thermoelectric temperature control system during the real-time use of the thermoelectric temperature control system. An alternate embodiment includes a liquid-to-liquid heat exchanger system to improve the efficiency of the system.
