Nextreme Thermal Solutions has announced a new series of thin-film thermoelectric modules that offer higher cooling capacity, robust mechanical design, and source-matched heat-flux density for easier integration into existing electronic systems. At only 1.1 mm high, the new eTEC MA8000 series provides low-profile thermal management for medium heat-flux applications in markets including photonics, electronics, test and measurement, and aerospace. The MA8000 series includes five new modules that can pump from 10 to over 80 watts of heat at an ambient temperature of 25 °C with footprints ranging from 63 to 375 mm2. With heat-flux densities ranging from 16 to 22 W/cm2, the MA series offers the ability to match thermoelectric-cooling designs more easily to heat sources and existing convection-based heat-rejection systems. The new modules fill the gap between traditional thermoelectrics that offer 6 to 8 W/cm2 and Nextreme's HV series that pumps heat in excess of 100 W/cm2. The MA8000 series features a high-strength seal ring made from Cirlex polyimide film that provides mechanical isolation across the thermoelectric device, virtually eliminating vertical force and sheer issues. The seal ring also serves as a barrier to moisture and other contaminants that could affect the performance of the module. "The introduction of the MA series significantly expands our thin-film product line," said Dave Koester, vice president of engineering for Nextreme. "The greater cooling capacity, lower heat-flux density, and robust design will open up new applications for our thermoelectric products." Commercial shipments of the eTEC MA8000 series will begin in the first quarter of 2013. Nextreme recommends the use of its thermal modeling, design, and engineering services to deliver fully-optimized thermal-management designs when using the MA series. Nextreme routinely conducts analytical and numerical thermal modeling at all design levels from component to module to subsystem.
