A two stage evaporative cooling device has a central chamber, divided into an upper chamber and a lower chamber by a divider, one or more heat exchange units surrounding the central chamber; an upperfan arranged above the upper chamber and a lower fan arranged below the lower chamber; and a water circuit; wherein each heat exchange unit comprises an evaporative cooling element and an air to waterpre-cooler, the pre-cooler being placed ahead of a lower portion of the cooling element and the water circuit is arranged to irrigate the cooling element and collect the irrigated water below the cooling element for delivery to the pre-cooler whereby pre-cooled air may be drawn inwardly through the pre-cooler and the lower part of the cooling element by the lower fan and ambient air may be drawninwardly through the upper part of the cooling element by the upper fan. 种两级蒸发冷却装置具有中心室，该中心室由分隔器分隔成上室和下室；包围中心室的个或多个热交换单元；布置在上室上方的上风扇和布置在下室下方的下风扇；以及水回路；其中，每个热交换单元包括蒸发冷却元件和空气对水预冷却器，该预冷却器放置在冷却元件的下部之前，并且水回路布置成灌注冷却元件并在冷却元件下方收集灌注水，用于
