Thermoelectric, or Peltier Cooling Modules (also known as TECs or TEMs) come in a wide variety of types and sizes. While typically used for cooling, they can also be used for heating (by reversing the electric current flow) and even power generation.
Please note that thermoelectric modules must be used with a heat sink. These heat sinks almost always need to be fan or liquid cooled to have a sufficiently low thermal resistance. Improper heat sinking can cause damage to the module. Be sure to review our FAQ's regarding reliability and our recommendations for using pulse-width modulated temperature controllers.
