摘要

An evaporative cooler for cooling a fluid contained in an array of spaced heat exchange elements by heat transfer to a cooling liquid flowing downwardly around the elements in counter current flow to an upwardly flowing gas is provided. The evaporative cooler includes a casing (1) housing the array (2) of spaced heat exchange elements, the gas flowing upwardly through the casing, and humid gas leaving the casing at an upper end; a restrictor (3) comprising a series of apertures (3a) located below the array of spaced heat exchange elements; the spaces between the heat exchange elements being aligned with the apertures, to provide substantially straight upwardly directed gas-flow channels through the heat exchange array; gas being drawn into the casing through the restrictor apertures and producing a pressure drop sufficient to inhibit loss of cooling liquid from a lower end of the cooler; and a coalescer (6) located above the heat exchange array, such that liquid droplets entrained in the upward gas flow are captured and coalesced to a size whereby coalesced liquid droplets falls down onto the heat exchange array.
