  • Patent number: 5657641
    Abstract: A cooling system for cooling warm air within the interior of a closed electrical cabinet containing electronic equipment or the like, comprising an enclosure adapted to be mounted on an exterior surface of the cabinet. The interior of the enclosure is separated into an internal circulation region and an external circulation region. Ambient air for removing heat from a condenser coil is drawn into the external circulation region through the bottom of the enclosure and the ambient air is also discharged out the bottom of the enclosure at a higher velocity than the ambient air being drawn into the bottom of the enclosure.

  • Patent number: 5545841
    Abstract: A seamless, light weight container that provides two levels of liquid and gaseous containment. The container has removable covers that have a double seal which allows confirmation of seal integrity prior to shipment by applying a vacuum or pressure to the internal space between the inner and outer seals. This close-out vacuum or pressure test can be completed within minutes and it provides certification that the container seals meet design criteria for quick turn-around in spacecraft environments.

  • Patent number: 5509468
    Abstract: An assembly, and associated method, for dissipating thermal energy contained in a circuit element of an electrical circuit which is releasably connectable with a substrate to form an electrical connection with the substrate when connected therewith. A fluid conduit extends through a plate member which is positionable proximate to the circuit element to be moveable therewith. The fluid conduit is coupled to a fluid manifold when the electrical circuit forms the electrical connection with the substrate. Coolant fluid is supplied to the manifold and, when the fluid conduit is coupled to the fluid manifold, also the fluid conduit. Thermal energy generated during operation of the electrical circuit is transferred to the coolant fluid flowing through the fluid conduit. The location of the fluid conduit is repositionable responsive to reconfiguration of the electrical circuit.

  • Patent number: 5474120
    Abstract: A cooling system is provided for compartments containing a heat generating apparatus, such as solid state variable speed constant frequency system, whose functionality is essential and whose cooling needs vary significantly during use. A main coolant channel is used to provide cooling to the heat generating apparatus under normal operating conditions. During an overtemperature condition; an auxiliary coolant channel provides additional coolant to the heat generating apparatus. Both of the channels are partially disposed within the heat generating apparatus, and they are both completely separate and free of fluid communication with each other. Each channel also contains a pump, such as a fan, for applying a motive force necessary to deliver the coolant to the heat generating apparatus.

  • Patent number: 5467607
    Abstract: An air conditioning control system monitors the temperature in the vicinity of electronic equipment using one or more sensors placed either in the equipment area or at the outlet of an air conditioning duct or vent. The temperature sensors supply signals to a microprocessor that is programmed to adjust the output of a system controller such that the amount of cooling provided by the air conditioning system is controlled. Illustratively, when the air conditioning system is restarted after a power failure, the power applied to one or more air conditioning fan motors is controlled, such as by throttling the motors down to an acceptable speed, to in turn control the cooling effect on the equipment. The amount of cool air produced by the air conditioning system is detected by the sensors, thereby forming a feedback control loop.

  • Patent number: 5410448
    Abstract: A parallel air flow system which automatically maintains proper coolant flow regardless of the number of circuit boards installed in an enclosure. The enclosure is constructed such that air flow path through any one slot does not affect the air flow through any other slot. Proper air flow through the entire system is maintained by an air flow sensor disposed in an air flow path having a known air flow resistance. This sensor controls the speed of an air-mover in order to maintain a constant predetermined air flow through the known resistance, in such a way that a constant static air pressure is maintained at each slot. Baffle modules are preferably inserted into the enclosure to prevent air flow into any empty slots, to reduce the total air volume necessary to achieve the predetermined static pressure, thereby reducing the audible noise generated by the air-mover.

  • Patent number: 5353863
    Abstract: A pentium CPU cooling device includes a radiating flange made of radiated structure and mounted on the CPU of the mainframe of a computer system by clamping plates for sending out heat from the CPU radially toward the top, an electric fan fastened to the radiating flange by screws and controlled to cause currents of air for carrying heat away from the radiating flange.
