[0037] Deflector 130 may include a base layer 130B having a plurality of openings 130P adapted to allow the airflow 20 through and a plurality of overhangs 130V spaced apart from each other and overhanging the plurality of openings 13OP. Plurality of overhangs 130V may be adapted to allow the airflow 20 from the plurality of openings 130P to flow therebetween and prevent the waterflow 10 into the plurality of openings 130P and direct the waterflow 10 into the second evaporative cooler 120. [0038] Referring to Fig. 1, the deflector 130 may include a louvred panel 132 having a plurality of overlapping panels 132P and a plurality of gaps 132G therebetween. In operation, the waterflow 10 from the first evaporative cooler 110 flows onto the plurality of overlapping panels 132P and is directed into the second evaporative cooler 120 and the airflow 20 from the second evaporative cooler 120 flows through the plurality of gaps 132G. [0039] Fig. 3A shows a sectional view of an exemplary embodiment of a deflector 330. Fig. 3A is a sectional view along line A-A in Fig. 3B. Deflector 330 may include the base layer 330B having the plurality of openings 33OP adapted to allow the airflow 20 through. Base layer 330B may also be adapted to receive and channel the waterflow 10 to the second evaporative cooler 320 (not shown in Fig. 3A). Deflector 330 may also include a top layer 330T having the plurality of overhangs 330V spaced apart from each other and overhanging the plurality of openings 33OP. Each of the plurality of overhangs 330V may be adapted to receive and channel the waterflow 10 to the base layer 330B. As shown in Fig. 3A, the base layer 330B may be a covered tray and the plurality of openings 330P may be a plurality of through holes for the airflow 20 to go through. Base layer 330B may be in fluid communication with the second evaporative cooler 320 such that waterflow 10 collected therein may be channelled to the second evaporative cooler 320. Each of the plurality of overhangs 330V may extend from the base layer 330B. Each of the plurality of overhangs 330V may include a funnel 330L with a wide top 330W that overhangs the openings 330P and a narrow bottom 330B connected to the base layer 330B. Each of plurality of overhangs 330V may be in fluid communication with the base layer 330B such that the waterflow 10 flowing thereinto may flow into the base layer 330B, which may direct the waterflow 10 to the second evaporative cooler 320. Top layer 330T may include a plurality of secondary overhangs 330V2 overhanging the plurality of overhangs 330V. Each of the plurality of secondary overhangs 330V2 may extend from the base layer 330B and extend through the plurality of overhangs 330V. Each of the plurality of secondary
