Liquid Cooling with MicroChannel Enhanced Base Plates are Making In-Roads into the High-End Server Market
Keywords: Cooling, Micro, Liquid
A myriad of liquid cooling systems have been serving the “over clocker and gaming” markets for some time. The mainstream commercial server industry is closely watching the technical evolution and advancement of this liquid cooling product technology as costs come down and reliability and thermal performance improve. New micro-channel construction on the base plate surface is one major factor in the advancement of this liquid cooling segment. In this presentation Wolverine Tube would like to demonstrate the thermal performance and pressure drop of several new commercial micro-channel, cold plates along with some initial concepts in test for future liquid cooling systems for advanced micro-processors. • Fundamental benefits experienced with liquid cooling systems in the server market • Outline of the different manufacturing approaches to micro-channel geometries • Strengths and weaknesses of the different approaches • Review an inventory of different cold plate surfaces in use today • MicroCool™ comparison to diffusion bonded photo-resist cold plate stack • Benefits of a manifold system: IBM, CoolIT and Univ. of MD • IBM Zero Emissions challenge for a liquid cooled cool plate and cooling loop for a high-end blade server • Two phase cooling and future concepts
