Thermoelectric Refrigeration Technology

With the development of advanced semiconductor thermocouple materials combined with ceramic substrates, such devices have become commercialized. Thermoelectric coolers are solid state heat pumps that require a heat exchanger to dissipate heat using the Peltier effect. During operation, the DC current of the thermoelectric cooler creates heat conduction and temperature differences across the ceramic substrate, causing one side of the thermoelectric cooler to be cold while the other side is hot. A standard single-stage thermoelectric cooler can achieve temperature differentials of up to 60°C.

Benefits of Thermoelectric Cooling

Thermoelectric coolers have several advantages over other cooling technologies:

Solid-state construction with no moving parts for higher reliability.

Units can be installed in any orientation.

Thermoelectric coolers can cool equipment to temperatures well below ambient. Lower temperatures can be achieved by using multi-stage thermoelectric coolers in a vacuum environment, down to minus 100°C. Thermoelectric devices can be heated and cooled by simply reversing the polarity, which changes the direction of heat transfer. This enables very precise temperature control, up to ±0.01°C can be maintained under steady state conditions.

In heating mode, thermoelectric coolers are more efficient than traditional resistive heaters because they generate heat from the input power source, plus additional heat from the action of the heat pump. These devices are environmentally friendly as they do not use chlorofluorocarbons and have very little electronic noise.

Thermoelectric coolers can be used as energy harvesters, converting waste heat into usable output DC power.
