A giga-bit interface convertor module bracket assembly having upper and lower ground springs. The upper ground spring has upper wing-shaped springs in the upper part of the front opening of the bracket assembly and a pair of upper spring tabs on the interior of the bracket assembly. The lower ground spring has lower wing-shaped springs in the lower part of the front opening of the bracket assembly and a pair of lower spring tabs on the interior of the bracket assembly. When a giga-bit interface convertor module is inserted in the bracket assembly through the front opening, the upper and lower spring tabs bias against the top and bottom walls of the giga-bit interface convertor module to provide grounding thereto. Additionally, the upper and lower wing-shaped springs contact with a front panel of an enclosure or bracket or an electronic card on which the bracket assembly sits. The lower ground spring is provided with a bottom ground spring to contact the electronic card for grounding.

A refrigeration system for a disk drive storage is provided. The refrigeration system employs pairs of thin conducting plates, each pair of which is placed so as to sandwich a disk drive. The refrigeration system conducts heat generated from the disk drives via the thin conducting plates, heat pipes coupled to the thin conducting plates, a back plate and a chilled manifold. The heat is further removed as a refrigerant travels through to a compressor and then to a condenser, both of which are connected to the chilled manifold. In this way, the disk drive storage is able to increase its capacity from a bank of twelve disk drives to fourteen disk drives for a 1 inch disk drive storage and from eight disk drives to nine disk drives for a 1.6 inch disk drive storage system, thereby realizing an increased density system without sacrificing a low operating temperature.

An electronic assembly that includes a heat pipe that extends from an electronic card. The heat pipe has a condenser end that can be inserted into an elastic thermally conductive port of a manifold. The manifold may be part of a cooling system that removes heat from the condenser end of the heat pipe. The port may include a metal filled elastomeric material. The elastic characteristic of the material may accommodate for tolerances in the system and insure contact between the material and the heat pipe. The metal filler provides a thermal path from the heat pipe to the manifold. The elastic port allows the heat pipe to be coupled to the manifold without any fasteners.

An electronic system that may include an electronic card sub-module that is electrically connected to, and in fluid communication with, an electronic card module. The electronic card module can be mated with a motherboard and coupled to a manifold of a cooling system that provides a cooling fluid to the modules. The cooling fluid can flow directly onto integrated circuits or integrated circuit packages located within the modules. Each module may have an electrical connector and a fluid connector that allows the sub-module to be plugged into the module, and the module to be plugged into the motherboard and manifold without using any tools or hardware.

A computer housing which includes a chassis that has a first compartment and a second compartment. The first compartment includes a first electronic assembly and a first fan that creates a flow of air through the compartment to create a compartment pressure that is less than an ambient pressure. The second compartment contains a second electronic assembly and a second fan which produces a flow of air that creates pressure within the compartment that is greater than the ambient pressure. The housing also contains an inner wall which separates the first compartment from the second compartment to inhibit air flow between the compartments.

A bracket for an electronic card that is inserted into a slot of a chassis. The chassis has a pair of opposing walls with guide channels that guide the card into a motherboard. The bracket includes a pair of low friction guide rails that slide along the guide channels. Attached to the guide rails are a pair of grommet dampers which are pressed between the edges of the card and the guide channels when the card is inserted into the chassis. The grommets dampen any shock or vibrational load that is transferred from the chassis to the card. The bracket also has a pair of spring clips that are attached to the card and pressed into the guide channels to provide an electrical path between the card and the chassis. The electrical path discharges electrostatic charges on the card and provides a ground path for any electromagnetic fields generated or received by the card. The bracket further includes a lever pivotally connected to one of the guide rails. The lever has a latch that can engage the chassis to secure the card in the installed position. The lever has rounded edges and a width no greater than the thickness of the card to allow cooling air to readily flow past the card. The pivot point of the lever is located above the card so that the bracket may be assembled to cards of various lengths.

A computer chassis cover that pushes an electronic card into a motherboard. The cover is pivotally connected to the chassis and can be rotated between an open position and a closed position. The cover encloses an electronic card that is plugged into a motherboard. When in the closed position, the inner surface of the cover is separated from the motherboard by a distance that is approximately equal to the distance between the motherboard and a top edge of the electronic card. When the cover is in the closed position the card is pushed into a fully mated position when the card is in a fully mated position. If the electronic card is higher than the fully mated position, the cover will engage and push the card into the motherboard. To install an electronic card, the card is initially partially plugged into a connector mounted to the motherboard. The cover is then rotated into the closed position to engage and push the electronic card further into the motherboard connector to the fully mated position. The cover has wide handle area that widely distributes the insertion force of the card. The distributed force reduces the end user discomfort when pushing the card into the motherboard.

A card guide that both restrains an installed electronic card and allows the card to be inserted into a computer chassis in a direction that is parallel to the motherboard of the computer. The card guide extends from a beam that is cantilevered from a frame of a computer chassis. The card guide has a groove that guides an edge of the electronic card so that the card is aligned with a connector of the motherboard. The card guide also has a ramp that guides the card into the groove in a direction parallel with the motherboard and perpendicular to the groove. The card is installed by initially pushing the electronic card along the ramp until the edge of the card snaps into the groove. The cantilevered beam is deflected by the installation force of the user to allow the card to move down the ramp. Once in the groove the electronic card is pushed in a direction perpendicular to the motherboard to plug the card into the motherboard connector. A corner of the installed electronic card is restrained from movement by a ramped portion of the groove. The electronic card is removed from the chassis by sliding the card corner along the ramped portion. The movement of the corner up the ramped portion deflects the beam so that the electronic card can be removed from the chassis in a direction parallel with the motherboard.

A modular circuit board placement system is disclosed that provides for flexible placement of daughterboards, for minimal bus signal path lengths between motherboard and daughterboards, and for ease of installation and removal of daughterboards. The placement system employs dual height bus connectors, a stepped back panel, easy to engage and disengage dual height card retainers, filler panels that also function as module mounts, and multipurpose circuit card handles that facilitate removal of daughterboards. Daughterboards have a two-tier staggered arrangement above the motherboard. Each daughterboard has a signal transfer end that electrically connects to the motherboard through one of the dual height bus connectors, and a back panel connector end that couples to the back panel with an accessory connector or with a filler panel that functions as an electromagnetic interference shield. Dual height card retainers that require no tools to operate function as retaining means to prevent daughterboards from working lose from bus connectors during shipment. Multi-purpose circuit card handles are employed to facilitate installation and removal of daughterboards during field upgrade and field service, or to function as circuit card retainers in systems having only one tier of daughterboards.
