Counterflow hybrid evaporative heat exchanger

A heat exchange system, comprising:

• a first air inlet on a first wall of the heat exchange system;
• a second air inlet on a second wall of the heat exchange system, the second wall being opposite to the first wall, wherein the first air inlet and second air inlet are configured to receive air;
• fill media positioned vertically above the first air inlet and second air inlet, the fill media extending between the first wall to the second wall;
• a third air inlet on a third wall of the heat exchange system, the third wall connecting the first wall to the second wall,
• a coil casing extending below a third wall, wherein the coil casing is fluidly downstream of the third air inlet and includes a plurality of coils;
• a first chamber located vertically below the third wall, the first chamber extending vertically parallel to the coil casing;
• and
• a first opening in the coil casing, the first opening being configured to distribute air from the first air inlet, second air inlet, or third air inlet to the first chamber.

A heat exchange system, comprising:

• a first air inlet with an upward-facing opening configured to receive air flowing in a substantially downward direction;
• a first spray system positioned beneath the first air inlet and configured to distribute water;
• a coil section positioned beneath the first spray system, the coil section including a plurality of heat exchange coils;
• a first horizontal air inlet with a laterally-facing opening configured to receive air flowing in a substantially horizontal direction;
• a fill section positioned above the first horizontal air inlet, the fill section configured to facilitate evaporative cooling;
• a second spray system positioned above the fill section and configured to distribute water onto the fill section;
• a first chamber adjacent to the coil section, the first chamber being configured to receive air passing through the coil section;
• and
• a first fan system configured to discharge air from the first chamber.
