10 may be evaporative cooled by the cooled airflow 20 from the second evaporative cooler 120. Cooled waterflow 10 from the first evaporative cooler 110 may be directed to the second evaporative cooler 120 to be further cooled. Compared to the conventional cooling tower with a heated waterflow entering the chamber and the infill, the thermal efficiency and effectiveness of the cooling apparatus 100 is relatively higher. Moreover, the waterflow 10 that is further cooled by the second evaporative cooler 120 cools the airflow 20 entering the cooling apparatus 100 further to a lower temperature as compared to the airflow temperature entering the conventional cooling tower via the cross-flow infill. Hence, the cooler airflow 20 from the second evaporative cooler 120 may be directed to the first evaporative cooler 110 to further cool the waterflow 10 entering the first evaporative cooler 110. As clearly shown the cooling effectiveness and efficiency of the cooling apparatus 100 is better and higher than the conventional cooling tower. [0031] As shown in Fig. 1, the cooling apparatus 100 may include a chamber 140 having a top section 140T, a centre section 140C and a bottom section 140B. First evaporative cooler 110 may be disposed at the top section 140T and the second evaporative cooler 120 may be disposed at the bottom section 140B such that the first evaporative cooler 110 may be disposed above the second evaporative cooler 120. Deflector 130 may be disposed in the centre section 140C between the first evaporative cooler 110 and the second evaporative cooler 120. In terms of waterflow 10, the first evaporative cooler 110 may be considered to be disposed at upstream of the deflector 130 and the second evaporative cooler 120 may be considered to be disposed downstream thereof. [0032] Referring to Fig. 1, the cooling apparatus 100 may include a water inlet 142 at the top section 140T and a water outlet 144 at the bottom section 140B such that the waterflow 10 enters the chamber 140 at the top section 140T and exits it at the bottom section 140B. Cooling apparatus 100 may include a plurality of nozzles 142N connected to the water inlet 142 and extending horizontally or laterally across the chamber 140 to distribute the waterflow 10 evenly across the width of the chamber 140. Cooling apparatus 100 may include an air inlet 146 at the bottom section 140B of the chamber 140 and an air outlet 148 at the top section 140T such that airflow 20 may enter the chamber 140 via the air inlet 146 at the bottom section 140B and exits via the air outlet 148 at the top section 140T. Cooling apparatus 100 may include more than one air inlet 146 and more than one water outlet 144. First evaporative cooler 110 may be
