deflector 530 and the first evaporative cooler 510 to guide the airflow 20 from the deflector 530 to the first evaporative cooler 510. As the portions of airflow 20 from the second evaporative cooler 520 are guided by the plurality of bottom guides 560B to the deflector 530 and flows through the deflector 530, the same portions of airflow 20 may be guided by the plurality of top guides 560T from the deflector 530 to the respective portions of the first evaporative cooler 510. For example, the portion of airflow 20 at the top portion 520T of the left side and right side of the second evaporative cooler 520 may be directed to the left side portion 510L and right side portion 510R of the first evaporative cooler 510. The portion of airflow 20 at the bottom portion 520B of the left side and right side of the second evaporative cooler 520 may be directed to the centre portion 510C of the first evaporative cooler 510. In this way, the airflow 20 exiting from the second evaporative cooler 520 may be directed to the first evaporative cooler 510 with minimal interference hence reducing the resistance of the water flow and airflow 20 between the airflow 20 and waterflow 10. [0047] It can be appreciated that the cooling apparatus 500 provides a stable feedback cooling loop. When the water, e.g. from the condenser at high temperature, enters the cooling apparatus 500 via the water inlet 542, the waterflow 10 is being sprayed onto the first evaporative cooler 510 using the plurality of nozzles 542N. As the waterflow 10 flows through the first evaporative cooler 510, it is cooled by the counterflow airflow 20 before exiting the first evaporative cooler 510. A cooling effect is produced through the first evaporative cooler 510 and especially at the bottom side thereof, thus reducing the temperature of the waterflow 10 exiting from the bottom side of the first evaporative cooler 510. Consequently, the temperature of the waterflow 10 entering the second evaporative cooler 520 is reduced compared to a cooling apparatus 500 without the first evaporative cooler 510. In turn, due to the cooling effect of the cross-flow between the waterflow 10 and the airflow 20 within the second evaporative cooler 520, the temperature of the waterflow 10 exiting the second evaporative cooler 520 at its bottom portion 520B is further reduced. As such, the temperature of the airflow 20 exiting from the second evaporative cooler 520 is much lower compared to the waterflow 10 entering the second evaporative cooler 520. Due to the lowered temperature of the waterflow 10 in the second evaporative cooler 520 as a result of the cooling effect by the first evaporative cooler 510 and the second evaporative cooler 520, the incoming airflow 20, i.e. ambient air, into the second evaporative cooler 520 may be cooled to a temperature lower than that of a conventional cooling tower. Consequently, the cooled airflow 20 exiting from the second evaporative cooler
