Abstract
A rear door heat exchanger is used to cool exhaust air as it exits a rack containing a plurality of computing devices. An air flow rate is determined for each of the plurality of computing devices within the rack, wherein each of the plurality of computing devices includes a fan drawing air through the computing device. The position of a baffle or louver is controlled to allow exhaust air to bypass the rear door heat exchanger in response to determining that the total air flow rate through the plurality of computing devices exceeds a predetermined air flow capacity threshold of the rear door heat exchanger.
