Case Studies > Server Rack Cooling 
Overview 
TES were approached by a leading cabinet manufacturer with a requirement to directly cool high density server racks. Our engineers were faced with a challenge to design a packaged unit capable of dissipating 20kW from an adjacent cabinet/s. We were given a maximum width of 300mm to fit fans, a heat exchanger, controls, condensate collection system, and all the associated pipe work, etc.  
 
By designing a heat exchanger assembly which forms the backbone of the unit we were able to offer a very compact solution which fit the client’s specification.  
The layout includes fan drawers which can be “hot swapped” without stopping the unit. These can either directly cool an adjacent cabinet by re-circulating air, or when used in a “hot isle” configuration discharge out of the unit. 
The cooler measures incoming air temperature, and controls chilled water flow through the heat exchanger and fan speed according to the heat load. The cooler operates at 24VDC from an integral inverter, this allows the cooler to be installed and operate anywhere globally.
