Deccan power products[pvt.] ltd. Since 1995 specializes in electronics, electricals, software, instrumentation, and tele communications. Thermoelectric cooling module [tecm] accomplishes the cooling action according to the peltier effect theory and utilizes the thermoelectric effect of semiconductor material. Reversing its current direction can change the heat flow direction of tecm and its cooling power can be adjusted by changing its operating current. Salient features of thermoelectric cooling module are as follows:
