A heat exchanger management system and a method of operating the heat exchanger management system. In one embodiment, the heat exchanger management system includes a memory and an electronic processor electrically connected to the memory and configured to operate one or more burners to transmit heat to a heat exchanger for a first period of time that deposits corrosive condensates on a passivation layer of the heat exchanger, deactivate the one or more burners for a second period of time, operate one or more blowers to move air across the heat exchanger at a temperature that evaporates the corrosive condensates on the passivation layer of the heat exchanger and increases an oxide thickness of the passivation layer on the heat exchanger, and reactivate the one or more burners after the second period of time.

A method of operating a heat exchanger is disclosed in which an electric field is applied to a hydrophobic surface having condensed water droplets thereon to reduce a contact angle between the individual droplet surfaces and the hydrophobic surface, and to increase droplet surface energy to a second surface energy level. The electric field is removed to increase the contact angle between the individual droplet surfaces and the hydrophobic surface, and to reduce droplet surface energy to a third surface energy level. The third surface energy level is greater than the first surface energy level and greater than a surface energy level for a free droplet. A portion of the droplet surface energy is converted to kinetic energy to detach droplets from the hydrophobic surface. The detached droplets are removed from the heat rejection side fluid flow path.
