Brief Overview of a Thermoelectric Module
A thermoelectric module "pumps" heat from one ceramic face to the other ceramic face when DC current is applied. Unlike the compressor in a standard refrigeration system that pumps Freon, thermoelectric modules use electrons to transfer heat. Thermoelectric modules can also work in reverse, generating DC current (power) if one side is hot and the other is cold.
This phenomenon was discovered in 1834 by Peltier, but did not realize commercial success until semiconductors were developed during the 20th Century. Thermoelectric cooling systems are currently found in many homes, laboratories, manufacturing facilities, hospitals, and in spacecraft and military applications. Since thermoelectric modules have no moving parts, they are quiet and reliable.
Solid State Cooling Systems incorporates domestic and internationally manufactured thermoelectric modules into complete temperature control systems for OEMs and end-users.
