allow the airflow 20 from the second evaporative cooler 420 to pass through to the first evaporative cooler 410. [0043] Fig. 4C shows a side elevation view of the exemplary embodiment of the deflector 430 as shown in Fig. 4A. As shown in Fig. 4C, the plurality of top channels 430CT may be disposed above the plurality of bottom channels 430CB. Both the plurality of top channels 430CT and the plurality of bottom channels 430CB may be inclined to direct the waterflow 10 to the side channel 430D. Both the plurality of top channels 430CT and the plurality of bottom channels 430CB may form a set of channels and there may be more than one set of channels disposed above each other in a deflector 430. Further, the sets of channels may be inclined alternately to form a zig-zag configuration. [0044] Fig. 5 shows a sectional view of an exemplary embodiment of the cooling apparatus 500. Cooling apparatus 500 may include the features described in the cooling apparatus 100 in Fig. 1. Cooling apparatus 500 may further include a plurality of guides 560 spaced apart from each other and adapted to guide the airflow 20 from the second evaporative cooler 520 to the first evaporative cooler 510. Plurality of guides 560 may include a plurality of parallel panels adapted to direct the airflow 20 from the second evaporative cooler 520 to the deflector 530. [0045] Second evaporative cooler 520 may be sectioned into a plurality of portions, e.g. a top portion 520T, bottom portion 520B and a middle portion 520M between the top portion 520T and the bottom portion 520B. As the waterflow 10 flows through the second evaporative cooler 520 from the top portion 520T to the bottom portion 520B, the waterflow 10 is cooled by the airflow 20 as it flows downwards. As a result, the waterflow 10 cools down further as it flows down the second evaporative cooler 520. As it can be appreciated, the waterflow 10 at the top portion 520T of the second evaporative cooler 520 has a higher temperature than the waterflow 10 at the bottom portion 520B of the second evaporative cooler 520 due to the cooling effect downstream. Therefore, the temperature of the waterflow 10, hence the temperature at the bottom portion 520B of the second evaporative cooler 520 may be cooler than the temperature at its top portion 520T. The airflow 20 exiting the second evaporative cooler 520 is saturated and at the same time, the temperature of the airflow 20 exiting from the top portion 520T of the second evaporative cooler 520 may consequently be higher than the airflow 20 exiting from
