Abstract:
A rack assembly includes a nineteen-inch sub-assembly coupled to a four-inch extension that comprises two substantially closed side panels adjacent to each other, two substantially open sides adjacent to each other, a closed top and bottom, a plurality of mounting flanges for attaching the extension to a nineteen-inch sub-assembly and a plurality of embossments for receiving mounting hardware for installing the sub-assembly and extension into a twenty-three-inch rack. The four-inch extension is formed not only to allow a nineteen-inch rack sub-assembly to be installed in a twenty-three-inch rack, but also is formed to conduct air exhausted from a side of the nineteen-inch subassembly towards a rear end of the twenty-three-inch rack.
Abstract:
A rack element for mounting electronic equipment thereon, including: a front portion, a rear portion, and a pair of side portions defining an interior of the rack element therebetween. The interior of the rack element is partitioned into a front section and rear section, wherein the front section defines an air duct and the rear section defines a power distribution section. The air duct has an opening at one end thereof for receiving cooling air from an air conditioning system, and the front portion of the rack element includes a plurality of openings therein for enabling the cooling air from the duct to exit therethrough for cooling equipment mounted therein. The power distribution section includes an opening at one end thereof for enabling power cables to enter the power distribution section for powering equipment when mounted on the rack element.
Abstract:
An electronic equipment enclosure (10) for housing electronic equipment (11), and broadly comprising a pivot bracket (22); a plurality of sleeves (24), each being associated with a transmit terminal (26), a receive terminal (28), protective circuitry (30), and test circuitry (32); a spreader plate (38); and a heat sink (40). The pivot bracket (22) allows for tilting an outer housing (12) up to 30° relative to a mounting surface. The separate and distinct transmit and receive terminals (26,28) maintain minimum cross-talk and interference levels. The protective and the test circuitries (30,32) are located on daughter boards adjacent each sleeve (24) so as to be easily accessible. The spreader plate (38) is operable to force the sleeves (24) into direct contact with the interior surface of the outer housing (18). The heat sink (40) is operable to facilitate conductive heat transfer between the sleeves (24) and the lid (18).
Abstract:
A cable management rack is provided within which or upon which a heat-generating device is mountable, and which encompasses a vertical rectangular frame open in a front and a rear of the frame. The rack includes a first upright and a second upright attached to opposite respective lateral sides of a base and a top member, and respective side-facing panels. Each of the panels defines a plurality of vent holes arranged in an array and permit the rack to receive a sideways flow of cooling air into a first side of the rack through one of the vent hole arrays for cooling a heat-generating device mounted between the panels, and permit the rack to discharge a sideways flow of exhaust air through the other vent hole array. Each of the array of vent holes may manifest a honeycomb pattern of vent holes, and each of the vent holes may manifest an hexagonal shape. A cable management system includes a cable management rack for accommodating a heat generating device, a first baffle mounted with respect to a first upright of the rack and for redirecting a rearward flow of cool air sideways from a space adjacent a front side of the rack, and a second baffle mounted with respect to a second upright of the rack and for redirecting a sideways flow of exhaust air from the rack and through the second upright into a space adjacent a rear side of the rack. A method of cooling a heat-generating device mounted in or on a cable management rack includes providing a sideways flow of cooling air into the rack and into the device.
Abstract:
A chassis and associated telecommunication circuit card are disclosed. The chassis has heat dissipation and flame containment features while accommodating a high density of the circuitry cards. Embodiments include an inner housing with a double-layer middle floor dividing the chassis into top and bottom chambers. Each layer has partially aligned slots, and an air gap is provided between the two layers. Embodiments also include a double-layer mesh cover with an air gap existing between the two mesh layers. Projections and grooves are provided on the inner surfaces of the inner housing to receive circuit cards having a guide on one edge and a fin on another. The circuit card includes conductor structures such as multiple board layers with paired and segregated conductors. The circuit card also includes some components positioned to cooperate with the ventilation features of the chassis and includes some components chosen for low-power consumption or reduced flammability.

Abstract:
An assembled telecommunication exchange cabinet, comprising a hollow body and a base, wherein the body comprises a set of front doors, left and right side doors, a top cover and a heat sink device. A plurality of inlets are disposed on the bottom surface of the body, and a telecommunication exchange device and terminal boards are accommodated inside the body. The body accommodates a Digital Subscriber Line Access Multiplexer and a telecommunication exchange device, which in turn, are connected to the corresponding terminal boards. The left and right side doors and the top cover can be subsequently opened separately after the set of front doors is opened. In addition, the heat sink device of the body is disposed under the top cover. The base of the cabinet is removeably attached to the body; and at least one battery holder is further disposed inside the base to accommodate at least one spare battery.
