Redundant assembly for a liquid and air cooled module

摘要

A redundant assembly for an air and liquid cooled module is provided. The redundant cooling assembly comprises an air and liquid cooled module having a cold plate in thermal communication with a side attached auxiliary drawer. The auxiliary drawer houses a heat exchanger, a liquid pump with piping such that the heat exchanger, the liquid pump with piping and the cold plate form a closed liquid cooling loop. The auxillary drawer also housing an air moving device such that air can readily pass through the air moving device and the heat exchanger in order to provide air cooling. In one embodiment of the invention, fins are disposed on the cold plate to provide cooling in case the pump or the air moving device or both encounter a failure. In alternate embodiments, multiple pumps and/or multiple air moving devices can be used with or without the cold plate fins to provide redundancies.
