【導讀】局部面積熱管理專家Nextreme最近開發出了一個新的MA8000系列薄膜熱電模塊，散熱能力更強，機械設計更堅固，高度只有1.1mm高，更容易集成進現有的電子系統。該系列有5個模塊，可在63到375平方毫米面積內抽出10到80瓦的熱量。
Nextreme Thermal Solutions recently 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 1.1mm high, the new eTEC MA8000 series is designed to provide low-profile thermal management solutions for medium heat flux applications in photonics, electronics, and aerospace markets.
Nextreme Thermal Solutions is the leader in micro-scale thermal management and power generation solutions.

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 W/cm2 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 6-8 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."
First customer shipments of the eTEC MA8000 series will begin in the first quarter of 2013. Pricing is available upon request.
