Abstract:
1. An apparatus for facilitating cooling of an electronics rack, the apparatus comprising: a heat exchange assembly configured to reside at an air inlet side of the electronics rack, wherein the electronics rack comprises the air inlet side and an air outlet side, the air inlet side and the air outlet side respectively enabling ingress and egress of air through the electronics rack, and wherein the heat exchange assembly comprises an air-to-liquid heat exchanger positioned for ingressing air to pass thereacross before passing through the electronics rack, the air-to-liquid heat exchanger being in fluid communication with a coolant loop for passing coolant therethrough, and the air-to-liquid heat exchanger with coolant passing therethrough dehumidifying the ingressing air to the electronics rack to lower a dew point temperature of air flowing through the electronics rack; a condensate collector disposed at the air inlet side of the electronics rack for collecting liquid condensate from the air-to-liquid heat exchanger's dehumidifying of the ingressing air to the electronics rack; and a condensate evaporator disposed at the air outlet side of the electronics rack and humidifying the air egressing from the electronics rack, the condensate evaporator being coupled in fluid communication with the condensate collector at the air inlet side of the electronics rack and evaporating the liquid condensate received therefrom.
