An evaporative cooler 10 comprises a housing 12 defining an inlet 14 for air. An air cooling arrangement 16 located in the housing between the inlet and an inlet to a duct 18 extending to an air outlet 20. A bath 24 for water is located towards a bottom region of the housing. Ducting 22 extends from the bath to a liquid outlet 26 in a top region of the housing, for releasing liquid onto the air cooling arrangement. The bath is configured to capture the released liquid. A fan 30 cooperates with the duct 18 to draw air through the air inlet, the air cooling arrangement and into the duct towards the outlet. The same electrical motor 32 is used to drive both the fan and the rotor or impeller of a water pump 34 for moving the liquid from the bath to the liquid outlet. |
