ELLIPTICAL TUBE COIL ASSEMBLY FOR EVAPORATIVE HEAT EXCHANGER Abstract of the Disclosure The present invention relates to a coil assembly for use in an evaporative parallel flow or counterflow heat exchanger wherein the heat exchanger comprises a conduit oriented in a vertical direction through which external heat exchange fluids flow in a generally vertical direction, the coil assembly being mountable within the conduit, the coil assembly comprising inlet and outlet manifolds and a plurality of tubes connecting the manifolds, the tubes including bights and segments extending generally horizontally across the conduit and connected to at least one bight, the bights being oriented vertically and connecting segments of the tube at different levels within the conduit, the bights of adjacent tubes being in contact with each other, the segments having a generally elliptical cross sectional shape such that the segments of adjacent tubes are spaced from each other in a direction generally normal to the flow direction. The elliptical segments may be angled in the same or opposition directions as long as the spacing is maintained between the segments of adjacent tubes. The bights may have a circular or elliptical cross section.
