Faster, more powerful and dense computing hardware generates significant heat and imposes considerable data center cooling requirements. Traditional Computer Room Air Conditioning (CRAC) cooling methods are proving increasingly cost-ineffective and inefficient. Studies show that using the volume of room air as a heat exchange medium is wasteful and allows for substantial mixing of hot and cold air. Further, it limits cabinet/ frame/rack density because it cannot effectively cool high heat density equipment that is spaced closely together. A more cost-effective, efficient solution for maximizing heat transfer and enabling higher heat density equipment frames can be accomplished by utilizing properly positioned "Phase change" or "Two-phase" pumped refrigerant cooling methods.
