Peltier cooling units offer easy installation and improved thermal performance

CUI Devices’ Thermal Management Group has added two new models to its Peltier cooling unit product offering. The CPM-2C and CPM-2H carry 7A and 8.5A current ratings respectively, adding to the 6A current rating of the earlier released CPM-2F. As complete Peltier cooling units, the models provide a tighter seal structure for water resistance and absorption of thermal stress and are easy to install. With extensive temperature deltas up to 85.9C (Th=50C) and 70mm x 70mm package sizes, these thermoelectric cooling units are ideal for industrial, refrigeration, and sealed applications where forced air cooling is not an option.

This unique construction uses a combination of thermally conductive resin between the ceramic and copper on the cold side of the module, high-temperature solder, and larger P/N elements made from a premium silicon ingot. When combined, these characteristics lessen stress on the module and improve performance during thermal cycling conditions, while facilitating faster, more uniform cooling.
