AET and Celsia Technologies signed an exclusive collaboration and distribution agreement in 2006, including the joint development of next-generation thermal solutions utilizing graphite and microfluidics. CL-1000 Series, the first in a series of active heat spreaders, is made up of a thin Cu Case, Fluid Channel and Vapor Spacer. The components make CL-1000 series ideal where heat pipes are too thick and/or where any of the following are important: large surface area, flatness, low weight & thin form factor. Effectove thermal conductivities ranging up to 5000 W/m-K.
