Patent number: 7950244Abstract: An apparatus for facilitating cooling of an electronics rack is provided. The apparatus includes an air-to-liquid heat exchanger and system coolant inlet and outlet plenums mounted to a door of an electronics rack. The inlet and outlet plenums are in fluid communication with the heat exchanger and respectively include a coolant inlet and coolant outlet in the top portions thereof. System coolant supply and return hoses are disposed above the electronics rack and respectively couple in fluid communication the inlet plenum to a system coolant supply header and the outlet plenum to a system coolant return header. The hoses are each flexible, partially looped and of sufficient length to allow for opening and closing of the door. Stress-relief structures are coupled to at least one end of the hoses to relieve stress on the ends of the hoses during opening or closing of the door.Type: GrantFiled: November 14, 2007Date of Patent: May 31, 2011Assignee: International Business Machines CorporationInventors: Madhusudan K. Iyengar, Roger R. Schmidt, Howard P. Welz

Patent number: 7946124Abstract: A temperature controlled storage facility includes a room having an enclosed structure, and a plurality of multi-level storage zones within the room. Each of the storage zones include a supply of temperature controlled air having two outlets, one outlet positioned adjacent to a top area of the storage area, and a second outlet positioned adjacent to an aisle, wherein pressure barriers are created to prevent air flow from migrating to other storage areas or to a return duct without cooling (or heating) all of the inventory in the storage zone.Type: GrantFiled: September 12, 2007Date of Patent: May 24, 2011Assignee: Leo A. Daly CompanyInventor: Jeremy John Klysen

Patent number: 7937963Abstract: The present invention is an architecturally advanced chiller unit having solid, insulated exterior walls adapted for the attachment of aesthetic surface treatments, pedestal supports for a bottom intake of ambient air, and separate chambers for electrical and hydraulic components. The roof houses inset modular fans adapted for topside maintenance and the roof also allows service accessibility to heat rejection components housed within the chiller unit enclosure. Heat removal is accomplished through angled heat exchangers also housed within the enclosure. Each enclosure has an end accessible vestibule that house electrical and refrigerant components. The chiller units design is also intended to allow the side by side placement of two or more units, for modularity. The improved aesthetic appearance of these units also eliminates the use of surrounding architectural parapet walls or screening units. The improved space effectiveness and modularity shall provide greater flexibility in building construction.Type: GrantFiled: October 2, 2006Date of Patent: May 10, 2011Inventor: Thomas Middleton Semmes
