a cooling apparatus and method including a plurality of heat - producing devices positioned in a plurality of cabinets arranged in a row that allows flow of a first fluid through the heat - producing devices and cabinets where the flow is directed from an upstream end of the row to a downstream end of the row . the cabinets have a space therebetween wherein a heat exchanger is positioned between and adjacent to the cabinets , thereby the cabinets and heat exchangers alternate in the row . each heat exchanger allows flow of a second fluid therethrough for cooling the first fluid . a fluid - moving device is positioned adjacent the heat - producing devices for encouraging flow of the first fluid through the cabinets &# 39 ; heat - producing devices and through the heat exchangers , thereby encouraging heat transfer in each of the heat exchangers from the first fluid to the second fluid .
