Abstract
A method comprising flowing a liquid through supply pipe couplings to a fin tube assembly of an air-to-liquid heat exchanger and through the fin tube assembly to return pipe couplings, wherein the fin tube assembly forms a central air flow pathway. The method further comprises passing air through components within a rack secured to the rear door heat exchanger and through the fin tube assembly and detecting an operating condition within the rack. The method then automatically moves the fin tube assembly from a retracted position to an extended position in response to the operating condition, wherein the retracted position directs substantially all of the air to exit the rack through the central air flow pathway, and wherein the extended position allows the air to exit through the central air flow pathway and also through first and second side air flow pathways.
