ATE1-71 TEC Modules

This series of TEC (Thermoelectric Cooler) modules, ATE1-71, has 71 pairs of Peltier elements inside with a maximumvoltage of 8.5 Volt, there are several options for maximumcurrent, resulting in different power gratings, as shown inTable 1 below. They are designed for precisely regulatingthe temperature of the target objects and can be controlledby our TEC controllers to build highly stable and efficienttemperature regulating systems. The ATE1-71 series TECscan be used with our thermistors as well to achieve preciseand stable temperature sensing.

The ATE1-71 series TECs come with highly flat bareceramic surfaces on both sides. They can be mounted ontoflat metal surfaces by inserting thin layers of thermallyconductive filler materials, the so-called thermal pads, orplacing a thin layer of thermal paste. When mounting, makesure that proper pressure is applied constantly to keep goodthermal contacting between the metal and the TEC plates,minimizing thermal resistance between them.

The TECs can withstand strong orthogonal forces applied tothe surface, but very vulnerable to tangent forces, especiallyshocking tangent forces. A small shocking tangent force cancause the Peltier elements to crack inside. The crack may notcause operation problems initially, but it will grow with time,causing the TEC resistance to increase slowly, by the end,the TEC will stop operating.
