The heat exchange assembly is supported by a crossbeam above the air inlet. The heat exchange assembly comprises a plurality of serpentine heat exchange tubes, each with heat exchange fins provided on its outer wall. The water cooler has the beneficial effect of increasing the heat exchange area by providing the heat exchange fins. Hot water transfers heat to the heat exchange fins through the walls of the heat exchange tubes.
