[0041] Fig. 4A shows a sectional view of an exemplary embodiment of a deflector 430. Fig. 4A is a sectional view along line B-B in Fig. 4B. Deflector 430 may include the base layer 430B having the plurality of openings 430P adapted to allow the airflow 20 therethrough and the plurality of overhangs 430V spaced apart from each other and overhanging the plurality of openings 430P. Plurality of overhangs 430V may be adapted to allow the airflow 20 from the plurality of openings 430P to flow therebetween and prevent the waterflow 10 into the plurality of openings 430P. In addition, the plurality of overhangs 430V may be adapted to direct the waterflow 10 into the second evaporative cooler 420 (not shown in Fig. 4A). As shown in Fig. 4A, the base layer 430B may include a plurality of bottom channels 430CB spaced apart from each other to form the plurality of openings 430P therebetween, such that the plurality of bottom channels 430CB may be adapted to channel the waterflow 10 to the second evaporative cooler 420. Plurality of overhangs 430V may include a plurality of top channels 430CT adapted to direct the waterflow 10 to the second evaporative cooler 420. Plurality of top channels 430CT may form the plurality of spaces 430S therebetween. Plurality of top channels 430CT may be disposed above the plurality of openings 430P and overlap the plurality of bottom channels 430CB to ensure that the waterflow 10 that flows through the plurality of spaces 430S may be received by the plurality of bottom channels 430CB to be directed to the second evaporative cooler 420. At the same time, the airflow 20 from the second evaporative cooler 420 may pass through the plurality of openings 430P and the plurality of spaces 430S to first evaporative cooler 410. [0042] Fig. 4B shows a top view of the exemplary embodiment of the deflector 430 as shown in Fig. 4A. As shown in Fig. 4B, the plurality of bottom channels 430CB may form a plurality of openings 430P therebetween and the plurality of top channels 430CT may be disposed over the plurality of openings 430P and overlap the plurality of bottom channels 430CB to prevent the waterflow 10 through the plurality of spaces 430S to enter the plurality of openings 430P. Deflector 430 may include a side channel 430D in fluid communication with the plurality of base layer 430B and the plurality of overhangs 430V, such that the side channel 430D may be adapted to receive the waterflow 10 from the base layer 430B and the plurality of overhangs 430V and direct the waterflow 10 to the second evaporative cooler 420 (not shown in Fig. 4B). From the top view of the deflector 430 as shown in Fig. 4B, the deflector 430 may provide a complete barrier to the waterflow 10 from the first evaporative cooler 410 and direct the waterflow 10 to the second evaporative cooler 410. At the same time, the deflector 430 may
