Novel peltier modules integrates thermally conductive resin

April 05, 2017 // By Julien Happich
CUI’s Thermal Management Group announced a new line of high performance Peltier modules that boasts superior performance and reliability, thanks to a novel structure.

The arcTEC 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 premium silicon ingot. The elasticity of arcTEC’s resin layer allows for thermal expansion and contraction during the repeated heating and cooling of normal operation, which reduces stress on the elements, resulting in a better thermal connection, superior mechanical bond, and no marked drop-off in performance over time. High temperature solder and larger silicon elements are incorporated to enable faster and more uniform cooling.
The CP20H, CP30H, CP39H, CP60H, and CP85H series all employ the arcTEC structure and range in size from 15 mm to 40 mm, with profiles as low as 3.1 mm. These thermoelectric modules are available with a ∆Tmax of 77°C (Th=50°C) and current ratings ranging from 2.0 A to 8.5 A.
