Abstract: A kit for providing front-access cable terminations for rear-access shelf unit mounted in a rack system may comprise a terminal block panel, a terminal block, a set of extension cables, a rear panel, and a baffle. The terminal block panel may be configured to mount to the shelf unit. The terminal block may be mounted to the terminal block panel to provide front-access terminations for the shelf unit. The set of extension cables may provide electrical connection between the terminal block and one or more terminals disposed on a back plane associated with the shelf unit. The rear panel may be configured to attach to the shelf unit and to cover the set of extension cables. The baffle may be configured for installation in the rack system above the shelf unit and removable for access to the front-access terminations. The baffle may be configured to direct air flow rising from the rear-access equipment to the rear of the rack.

Abstract: An apparatus for cooling electronics is disclosed. The apparatus generally relates to heat sinks that are operatively connected to electronics enclosures. The heat sinks may be part of the electronics enclosure, or alternately they may be operatively connected to the electronics enclosure. An enclosure preferably prevents solar radiation from striking the surface of the heat sink. At the same time, the enclosure allows air to flow over the heat sink, allowing heat to be dissipated.

Abstract: A double sided-double heat exchanger core includes a plurality of sets of fluid passageways separated by a plurality of “S” shaped thermally conductive walls. Each set includes a plurality of fluid passageways. Each thermally conductive wall is configured to separate fluid flow between adjacent sets and configured to separate fluid flow between fluid passageways of one of the adjacent sets. The heat exchanger core is configured to provide segregated fluid flow between adjacent sets of fluid passageways. This heat exchanger core is particularly applicable for cooling equipment cabinets, wherein the air used to cool the equipment is recirculated through a plurality of sets and ambient air flows through interlaced sets to cool the recirculated air.

Abstract: An equipment enclosure (12) includes an interior cavity (16) housing a plurality of equipment compartments (22) configured to form vertical stacks, and a lower compartment (24) for housing batteries and/or other equipment. Airflow through the lower compartment (24) is isolated from airflow within the interior cavity (16). Heat exchangers (52, 54) are included for cooling internal air circulating air within the equipment enclosure (12) with external ambient air. Each heat exchanger (52, 54) draws external ambient air indirectly through the lower compartment (24) and directly from the external environment, and exhausts the air back to the external environment. The external ambient airflow through each heat exchangers (52, 54) is used to cool internal air circulating within the enclosure (12). The cooled internal air is provided through an opening (38) positioned proximate the bottom of the interior cavity (16).
