Peltier Semiconductor Cooling Module Thermoelectric Cooler Plate
•Although Thermoelectric Effects principles were discovered in the 1800’s, most early work was on metal alloys, not thermoelectric compounds. it wasn’t until the introduction of semiconductor materials in the late 1950’s, that thermoelectric cooling became a viable technology for [small] cooling applications.
•The characteristics of TECs make them highly suitable for precise temperature control applications and where space limitations and reliability are paramount or refrigerants are not desired.
•TECs have several advantages over competing technologies, including:
–high reliability potential
–orientation-independence and compactness (high energy density).
•Based on these advantages, TECs now dominate certain applications, and new benefits continue to emerge.
•TECs in space have become relatively common; they provide temperature control for low noise amplifiers (LNAs), star trackers, and IR (infrared) sensors.
