ULT33186 Features & Specifications
Peltier Coolers have been around for quite some time now, based on the Peltier effect. The Peltier effect is the reverse of the Seebeck effect; a creation of a heat difference from an electric voltage. Using the Peltier effect, Ultra has created a cooling device which can force heat away from the CPU faster than it could travel by its own means.
The Peltier effect occurs when a current is passed through two dissimilar metals or semiconductors (n-type and p-type) that are connected to each other at two junctions (Peltier junctions). The current drives a transfer of heat from one junction to the other: one junction cools off while the other heats up; as a result the effect is often used for thermoelectric cooling. This effect was observed in 1834 by Jean Peltier, 13 years after Seebeck's initial discovery. Peltier coolers are also called thermo-electric coolers (TEC).
