TEC Cooler

Operating Principle

A thermoelectric (TE) cooler, also called Peltier cooler, which is a semiconductor-based electronic component that functions as a small heat pump. By applying a low voltage DC power source to a TE module, heat will be moved through the module from one side to the other. One module face, therefore, will be cooled while the opposite face simultaneously is heated. It is important to note that this phenomenon may be reversed whereby a change in the polarity(plus and minus) of the applied DC voltage will cause heat to be moved in the opposite direction. Consequently, a thermoelectric module may be used for both heating and cooling thereby making it highly suitable for precise temperature control applications.

Cooling Capacity

A typical single-stage thermoelectric module was placed on a heat sink that was maintained at room temperature and the module was then connected to a suitable battery or other DC power source, the“cold”side of the module would cool down to approximately -40°C. At this point, the TE module would be pumping in a relative thermal balance and would have reached its maximum rated “DeltaT”(Dtmax). If heat was gradually added to the module's cold side, the cold side temperature would increase progressively until it eventually equaled the heat sink temperature. At this point the TE cooler would have attained its maximum rated“heat pumping capacity” (Qmax).

Structure & Features

TEC Cooler consists of TEC elements, heat sinks, fans, control(option), shell and sealing material and so on, can be customized according to different requirements, so far JGalaxy has developed TEC cooler with lower noise (lower than 45dBA) and higher cooling efficiency (higher than 120%), which makes JGalaxy’s TEC cooler superior to similar products at domestic and overseas. TEC cooler can be designed with air cooling and liquid cooling, main features as below:

• Green products with cooling and heating functions;

• Small, light and easy to handle;

• Highly reliable, the service life of TEC cooling module is longer than 200,000 hours;

• Can be used with typical power supplies, with a ripple within 10%, and can be powered using typical rectifier power supply or switches;

• Low noise, the cooling part does not generate noise and the only noise of the TEC cooler is from the fan.
