Abstract: Field-adjustable rack systems for mounting communications equipment are disclosed, including an adjustable communications equipment rack where the rack is adjustable from a floor mounted configuration to a wall mounted configuration, and the overall width of the rack may be varied by adjusting the base and the top in a plurality of different configurations. Also, height adjustment to the communications equipment rack is disclosed where the height of the rack may be adjusted without removal of the existing mounted equipment from the rack. Height adjustments are made by coupling a plurality of extensions to the vertical side rails of the rack, to arrive at the rack height desired. Methods are described for field adjusting communications equipment racks into various configurations, including floor mounted configurations and wall mounted configurations in a plurality of widths and heights.

Abstract: A customizable, modular circuit breaker housing assembly having an optimized compact form factor for use with electrical and telecommunications equipment. The housing assembly is comprised of an interlocked arrangement of individual housing portions coupled at one end to an end housing portion, and to an end panel portion at an opposite end. The end housing portion and individual housing portions include a load bus chamber and a line bus chamber for receiving load and line bus members, and one or more alarm contact member receptacles for receiving at least one alarm contact member. The line bus member and the alarm contact members may be provided as individually segmented members. In other embodiments, the individual housing portions may include pass-through slots for inserting a common line bus bar, pass-through apertures for common contact members, or both. The line and load bus members are formed of extruded metallic members having substantially the same cross-sectional surface.

Abstract: A system and method for the stabilization of battery temperature by alternating airflow through an internal ductwork of a cabinet housing electronic equipment and circuitry. Ambient air is drawn through one or more intake vents or louvers provided with the cabinet housing. Regulated airflow through the ductwork allows the cabinet housing's thermal management system to direct either cooler ambient air during warm periods or heated air during colder periods through the cabinet to stabilize the battery temperature as well electronics equipment and circuitry housed in the cabinet. At least a portion of the heated air is expelled through one or more exhaust vents. Because no active components are used for stabilizing battery temperature, thermal regulation is achieved even during utility power outages. Further, thermal energy is provided without the possibility of igniting hydrogen gas products generated by the battery units present in the cabinet.

Abstract: A support structure for an electronic enclosure includes a base having a top wall, a bottom wall which is spaced apart from the top wall, a pair of spaced apart end walls disposed between the top and bottom walls, and a pair of spaced apart side walls disposed between the top and bottom walls. The walls are integrally attached and are disposed to form a hollow chamber. The top wall includes an aperture communicating with the chamber. Ballast is disposed within the chamber and is adapted to be inserted into the chamber through the top wall aperture. The base may be formed of rotationally molded plastic material.

Abstract: A modular enclosure includes multiple interlocking molded plastic components and panels to form an exterior structure for the enclosure. The exterior structure provides a protective and aesthetic housing which encloses and covers an interior enclosure housing electronic and mechanical equipment. The exterior interlocking components may be fabricated of plastic utilizing rotationally molding techniques to provide a hollow wall design resulting in structural rigidity and strength to the various external parts and components of the enclosure. The modularity of the present enclosure allows for easy replacement of exterior components without affecting operation of the equipment housed inside the enclosure.

Abstract: A thermal management device for an enclosure, the enclosure disposed in an environment exposed to ambient air and having an interior area for housing heat generating electronic components includes a heat exchanger having an evaporator portion and a condenser portion, the evaporator portion is adapted for mounting within the enclosure interior area adjacent to the heat generating electronic components. The condenser portion is exposed to the ambient air for removal of heat from the enclosure interior area generated by the electronic components adjacent to the heat exchanger evaporator portion. The device is incorporated in a system which includes an air duct disposed within the enclosure interior area. The duct includes an air inlet port and air outlet port. The ports communicate with the ambient air to thereby create an airflow path through the air duct from the inlet port to the outlet port.

Abstract: A housing (10) for a cooling fan (56) includes a first side wall (12) and a second side wall (14) separated by a front wall (16). A first wall portion (22) extends from the first side wall (22) toward the second side wall (14) and opposite from the front wall (16). A second wall portion (26) extends from the second side wall (14) toward the first side wall (12) and opposite from the front wall (16). A first flexible member (30) on the first wall portion (22) extends along the first side wall (12) and is arched toward the front wall (16). A second flexible member (32) on the second wall portion (26) extends along the second side wall (14) and is arched toward the front wall (16). A cooling fan (56) is inserted into the housing (10), compressing the first flexible member (30) and the second flexible member (32) that force the cooling fan (56) against the front wall (16). The front wall (16) may include tabs (42, 46, 48, 50) to enhance the ability to secure the cooling fan (56) within the housing (10).
