20120009862 | Cold aisle/hot aisle containment system for computer servers in a data center - A cold aisle/hot aisle containment system for cooling computer servers on a raised floor in a data center is provided. The system includes a pedestal support system and a cold aisle is defined by at least one row of air-grate floor panels located between at least two banks of server racks. The floor panels including a perforated top plate with a support frame. The support frame includes reinforcing beam members and directional air flow vanes. Computer server cabinets include a cold air inlet, in a front cabinet panel, and a hot air exhaust, in a back cabinet panel. The server cabinets are mounted in the banks of server racks so that the front panels are facing each other on opposite sides of the cold aisle. An air flow damper door is adapted to cover at least a portion of at least one of the front or back cabinet panels so that damper blade members operate to direct a flow of cooling air through the cabinets. | 01-12-2012 |
20120164929 | Directional flow raised floor air-grate - A directional flow raised floor air-grate is provided for the enhanced thermal management of a raised floor computer room. The air-grate includes a load bearing frame. The frame has four vertical girders connected, in a ninety-degree alignment, so that four corners of the frame are capable of supporting the air-grate as an air handling separation barrier on a raised floor pedestal support system. A plurality of vertical reinforcing beam members is connected to the frame so that the reinforcing beams are aligned in a longitudinal spaced relationship. At least two vertical airfoil vane members have an upper inclined and, lower vertical planar surfaces. These surfaces are demarcated by a longitudinal axis of the vane members. The vane members are connected to the frame in a crosswise spaced relationship to the reinforcing beam members, so that a plurality of openings are created between the reinforcing beams and the airfoil vanes. The upper inclined planar surface of the airfoil directs cooling air from a lower plenum of a raised floor through the openings on an inclined plane towards the cold air intake surfaces of a data server cabinet to be cooled. | 06-28-2012 |
20120289143 | RAISED FLOOR AIR GRATE ADAPTED MULTI-VANE DAMPER - A raised floor air grate panel adapted for a multi-vane damper and linkage assembly is provided. The air grate includes an upper and a lower surface and a support frame. The support frame is connected to the lower surface and includes reinforcement ribs, side walls on opposite sides of the support frame, and at least two downwardly projecting air-flow vanes. The air flow vanes define a generally rectangular air-flow control portion adapted to receive a multi-vane damper and linkage assembly so that the linkage is operable from the upper surface of the floor panel. | 11-15-2012 |
20130104464 | RAISED ACCESS FLOOR PANEL WITH REPLACEABLE INSERT | 05-02-2013 |
20130186015 | ARTICULATING CORNER RAISED ACCESS FLOOR PANEL - An articulating raised access floor panel is provided. The floor panel plate has upper and lower surfaces, four edges defining four corner portions, and a diagonal clear slot positioned at each of the corner portions. A diagonal channel member is connected to the lower surface at each of the corner portions so that the channel member extends axially and parallel with the clear slot. A bar is slidably received in each of the channel members. The bar includes a leveling screw capable of operation through the clear slot so that the plate is capable of vertical adjustment with respect to a pedestal support system. | 07-25-2013 |
20140123576 | Bi-Surfaced Raised Access Floor Panel and Cold Isle Forming System in a Data Center - A bi-surfaced raised access floor panel is provided. The panel is constructed with a cross-braced framework. A generally square plate is rigidly connected to an upper surface of the framework. The plate has four corner formations and is bisected symmetrically to define first and second halves. The first halve is substantially configured as a solid load hearing surface which is adapted to support a data processing server. The second halve includes a plurality of clear perforations capable of circulating an air flow as an element of a cold aisle forming installation in a data center. | 05-08-2014 |
20140216683 | Universal Telescopic Louvered Panel Attachment and System for Passive Stack Effect Cooling in a Data Center - A telescopic louvered panel and system for enhancing cold aisle and hot aisle passive stack effect cooling efficiency in a data center is provided. The panel has a panel frame with a pair of vertical side walls. Each of the side walls has a back flange portion with mounting apertures for mounting the panel frame to either one of a computer cabinet or server door. A series of horizontally telescoping blade members have opposite ends which are pivotally connecting the side walls. The blade members are capable of slidably adjusting a width dimension of the frame, and pivoting on a horizontal plane. A vertical tilt bar links the blades together so that the blades push to open and close in unison. | 08-07-2014 |
