Abstract: A multiple mode hybrid heat exchanger apparatus includes a frame assembly, an indirect heat exchange section, a spray system, an intermediate distribution basin, a direct heat exchange section, a vertical passage, a lower air inlet, a cold water collection basin, and a fan. The frame assembly includes a first end wall, a second end wall that opposes the first end wall, a first side wall that extends between the first and second end walls, and a second side wall that opposes the first side wall that extends between the first and second end walls. The direct heat exchange section is disposed below the indirect heat exchange section. The vertical passage is defined by the frame and the direct heat exchange section. The lower air inlet is defined by a plurality of openings n the direct heat exchange section. The lower air inlet is configured to provide an inlet for air into the vertical passage, The cold water collection basin is disposed below the direct heat exchange section.

Abstract: A support grid having a longitudinal axis, having a frame. The frame includes a series of columns that extend generally parallel to the longitudinal axis and a series of girts that intersect the series of columns to form a plurality of windows. The support grid also includes a first retainer integral with the frame. The first retainer extends from the frame into at least one of the plurality of windows at a first axial location. The support grid also includes slider portions that extend in opposed relation for the frame into the at least one plurality of windows.
