Abstract:
A system for removing heat from a plurality of electronic assemblies, comprising:A. at least one cabinet including brackets for supporting electronic assemblies in a vertical array between a first vertical airflow path extending along a first side of the cabinet and a second vertical air flow path extending along a second side of the cabinet, the second side being opposite the first side of the cabinet, B. at least one 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 from the plinth to the second vertical air flow path of the cabinet, at least one heat exchanger disposed along a plinth air flow path extending between the input and the output ports, and transferring heat from air passing along the plinth air flow path to a heat exchange medium passing through the heat exchanger, and at least one fan assembly disposed along the plinth air flow path for driving air through the heat exchanger, the output port, along the second air flow path of the cabinet, across the spaced apart electronic assemblies, along the first air flow path of the cabinet, through the input port; and C. at least one air flow distribution device for establishing a predetermined flow rate distribution through electronic assemblies supported on the brackets of the cabinet, wherein the distribution device extends vertically and laterally between a lower end nearer the plinth and an upper end further from the plinth, such that the upper end of the distribution device is closer to the brackets than the lower end.
