|Vaporizable Dielectric Fluid Cooling for IGBT and Power Semiconductor Applications|
|Keywords: Dielectric, Liquid Cooling, Tw-phase|
|System description for design goals and results for implementation of dielectric fluid cooling in a pumped two-phase system, now being commercialized for 4Q2008 shipments, including description of positive displacement pump developments for these applications, liquid cold plates, system performance, cost and performance comparisons with air- and water-cooled alternatives, operating parameters, system balancing, and maintenance. Data will be shown for cost comparisons with air-cooled drive systems using identical IGBT modules and system components and development of system components specifically intended for dielectric fluids. Selection of fluids and the corresponding impact on pump development required to provide compact, flow-through, positive displacement gerotor pumps will be described. Flow-through pump design is intended to provide lubrication to pump motor components for extended life. Use of two-phase dielectric liquids in a pumped system without the use of a compressor to achieve sub-ambient temperatures has attributes of merit for liquid cooling, as an alternative to water-based systems.|
