[0004] Therefore, it is necessary to improve the thermal effectiveness and efficiency of such cooling apparatus. Summary [0005] According to various embodiments, a cooling apparatus for cooling a waterflow is provided. Cooling apparatus includes a first evaporative cooler adapted to cool the waterflow therethrough, a second evaporative cooler adapted to receive and cool the waterflow from the first evaporative cooler therethrough, wherein the second evaporative cooler is adapted to receive an airflow therethrough to cool the waterflow therethrough and the first evaporative cooler is adapted to receive the airflow therethrough from the second evaporative cooler to cool the waterflow therethrough, and a deflector adapted to deflect the waterflow from the first evaporative cooler to the second evaporative cooler and allow the airflow from the second evaporative cooler to the first evaporative cooler therethrough. [0006] According to various embodiments, the deflector may include a first side and a second side behind the first side, such that the deflector may be adapted to direct the waterflow from the first evaporative cooler to the second evaporative cooler on the first side and allow the airflow therethrough from the second evaporative cooler to the first evaporative cooler to flow from the second side to the first side. [0007] According to various embodiments, the deflector may include a base layer comprising a plurality of openings adapted to allow the airflow through and a plurality of overhangs spaced apart from each other and overhanging the plurality of openings, such that the plurality of overhangs are adapted to allow the airflow from the plurality of openings to flow therebetween and prevent the waterflow into the plurality of openings and direct the waterflow into the second evaporative cooler. [0008] According to various embodiments, the deflector may include a louvred panel comprising a plurality of overlapping panels and a plurality of gaps therebetween, such that, in operation, the waterflow from the first evaporative cooler flows onto the plurality of overlapping panels and may be directed into the second evaporative cooler and the airflow from the second evaporative cooler flows through the plurality of gaps.
