Abstract
A cooling arrangement for a rack hosting electronic equipment and at least one fan comprises first and second air-liquid heat exchangers. A first one is mounted to the rack so that heated air expelled from the rack by the fan flows therethrough. The second one is mounted to the first one so that air having flowed through the first heat exchanger flows through the second heat exchanger. Each heat exchanger comprises a frame, an inlet receiving liquid from a cold supply line, an outlet returning liquid to a hot return line, and a continuous internal conduit forming a plurality of interconnected parallel sections. The cooling arrangement is mounted to the rack so that the first and second frames are parallel and adjacent. One interconnected parallel section of the first heat exchanger nearest to its inlet is proximate one interconnected parallel section of the second heat exchanger nearest to its outlet.
