A technique for climate control of, for example, base station circuitry within an enclosure involves placing base station circuitry within the enclosure and controlling the climate therein. A system according to this technique includes an enclosure suitable for use outside in a wide range of extreme weather conditions. A controller may, for example, control a fan tray with a heater to pull ambient air through a filtration unit, through the fan tray where the air is heated, and through cold start recirculation dampers.

Systems and methods for base station enclosures

A system for removing heat from a plurality of electronic assemblies including a cabinet having brackets for supporting electronic assemblies in a vertical array between a first vertical airflow path and a second vertical air flow path of the cabinet, and a plinth underlying the cabinet and having an input port receiving air from the first vertical airflow path of the cabinet, an output port transmitting air to the second vertical air flow path, a heat exchanger positioned in an air flow path extending between the input and the output ports, and a fan assembly for driving air through the heat exchanger and towards the input port. The system further includes at least one air flow distribution device establishing a predetermined flow rate distribution through electronic assemblies supported by the brackets.

An earthquake-resistant rack for electrical equipment including a base having access apertures for receiving wires and cable therethrough and mounting apertures for securing the base to a floor upon which the rack is mounted. The rack also includes a pair of vertically extending upright members have lower ends secured to opposite sides of the base, and each upright member has a web, opposing first and second flanges projecting from the web, and openings for mounting electrical equipment thereon, and a cross member extends between upper ends of the upright members. Moreover, the base includes a bottom plate, side channels extending at an angle between the bottom plate and the webs of the upright members, and a central channel extending horizontally between the side channels. The channels provide additional strength and stiffness to the rack, without adding substantial weight to the rack.
