Publication number: 20040060309Abstract: A system and method for reducing temperature variation among components in a multi-component system. In this respect, component temperatures are controlled to remain relatively constant (approximately within 5° C.) with respect to other components, while allowing for multiple fluctuating heat loads between components. A refrigeration system possessing a variable capacity (speed) compressor and a thermostatic expansion valve is utilized to control the flow of refrigerant through the refrigeration system. The temperatures of the components are reduced by metering the mass flow rate of the refrigerant cooling the components to compensate for the heat load applied to the refrigeration system. The temperature variation among the components is reduced by supplemental heaters independently providing heat to each respective component.Type: ApplicationFiled: September 30, 2003Publication date: April 1, 2004Inventors: Abdlmonem H.

Patent number: 6574104Abstract: A cooling system is configured to adjust cooling fluid flow to various racks located throughout a data center based upon the detected or anticipated temperatures at various locations throughout the data center. In one respect, by substantially increasing the cooling fluid flow to those racks dissipating greater amounts of heat and by substantially decreasing the cooling fluid flow to those racks dissipating lesser amounts of heat, the amount of energy required to operate the cooling system may be relatively reduced. Thus, instead of operating the devices, e.g., compressors, fans, etc., of the cooling system at substantially 100 percent of the anticipated heat dissipation from the racks, those devices may be operated according to the actual cooling needs.Type: GrantFiled: October 5, 2001Date of Patent: June 3, 2003Assignee: Hewlett-Packard Development Company L.P.Inventors: Chandrakant D.

Patent number: 6525936Abstract: An air cooled electronic system within an enclosure simultaneously provides different levels of cooling in response to the individual cooling needs of the various electronic components. In one embodiment, electronic system includes a plenum that has an inlet and a plurality of outlets with the inlet receiving air from outside the enclosure. A rate of airflow at the respective plenum outlets varies as a function of a static air pressure behind the plenum outlets and a shape of the respective outlets, the static air pressure being a function of the shape of a cavity within the plenum. The system also includes a plurality of air ducts respectively coupled to the plurality of plenum outlets, with each air duct having a length and an outlet characterized by an outlet size. A first one of the air ducts has an outlet that is disposed proximate a first subset of the electronic components and a second one of the air ducts has an outlet that is disposed proximate a second subset of the electronic components.Type: GrantFiled: April 30, 2001Date of Patent: February 25, 2003Assignee: Hewlett-Packard CompanyInventors: Abdlmonem H Beitelmal, Chandrakant D.

Patent number: 6490877Abstract: System and method for reducing temperature variation among heat dissipating components in a multi-component computer system. In this respect, component temperatures are controlled to remain relatively constant (approximately within 5° C.) with respect to other components, while allowing for multiple fluctuating heat loads between components. A refrigeration system possessing a variable speed compressor or a constant speed compressor is utilized to control the flow of refrigerant through the refrigeration system. The temperature variation among components is reduced by independently metering the mass flow rate of the refrigerant flowing into each component to compensate for the amount of heat load on each component. In this respect, the mass flow rate of the refrigerant entering into each of the evaporators is metered by valves located upstream from each of the evaporators.Type: GrantFiled: February 13, 2002Date of Patent: December 10, 2002Assignee: Hewlett-Packard CompanyInventors: Cullen E.
