Electronic Applications Division CeramCool® Liquid Cooling For Extreme Power Densities CeramCool® Liquid Cooling is one of the most efficient and reliable cooling systems on the market. No other design can achieve this system cooling capacity and still assure such a long lifetime. The ceramic heat-sink is perfectly electrically insulating and inert. Electrical circuits can be directly metalized on all its sides and can be populated with high-power components without creating any thermal barrier. The efficiency of the ceramic cooling system increases with the rising capacity of the complete power system – the hotter the better. i Liquid Cooling A LMOST A NY COOLING CA PACITY ! • Powerful packing densities up to 170 W/cm² • Electrical circuits without thermal barriers directly on CeramCool ® • S hortest possible thermal distance between heat source and heat drain: only 1 mm from heat slug • Any cooling liquid, any environment • Scalable • Homogenous cooling • Best break-through voltage with excellent thermal conductivity i Ceramic heat-sink H IGH LY EFFICIENT TH ER MA L MA NAGEMENT! • Ceramics = electrical insulation + thermal conductivity • CeramCool ® = heat-sink + circuit board • Chip on heat-sink • Direct and permanent connection of components • Increases system stability, reliability and lifetime • Lowest total thermal resistance Rtt • Individual layouts • UV-resistant • Excellent EMV CeramCool® Liquid Cooling: For almost any Cooling Capacity! CeramCool® Liquid Cooling The choice of ceramic material is decisive for the performance capability of the system. With the same exact geometry, Rubalit cools 290 W while Alunit 170 cools 640 W. All CeramCool ® systems are excellently suited for UV-applications. To aid comparability of the various cooling systems, all types were simulated using Luxeon Z LEDs.
