Abstract
Augmenting air cooling of electronics systems using a cooling fluid to cool air entering the electronics system, and to remove a portion of the heat dissipated by the electronics. A cooled electronics system includes a frame, electronics drawers, fans or air moving devices, and an inlet heat exchanger. A cooling fluid such as chilled water is supplied to the inlet heat exchanger, to cool incoming air below ambient temperature. Fans cause ambient air to enter the system, flow through the inlet heat exchanger, through electronic devices, and exit the system. An optional exhaust heat exchanger further transfers heat dissipated by electronic devices to the cooling fluid. Heat exchangers are pivotally mounted, providing drawer access. Segmented heat exchangers provide access to individual drawers. Heat exchangers are integrated into cover assemblies. Airflow guides such as louvers are provided at inlets and outlets. Cover assemblies provide a degree of acoustic and electromagnetic shielding.
