A regenerative evaporative cooler (REC) including: a plurality of dry channel units allowing indoor air to pass therethrough; a plurality of wet channel units formed to extract a portion of air, which has passed through the dry channel units, and formed to heat-exchange with the dry channel units; an evaporation water supply unit disposed at an upper portion of the wet channel units and supplying the wet channel units with evaporation water; and dry channel shields formed at an upper side of the dry channel units, allowing evaporation water supplied from the evaporation water supply unit to be introduced into the wet channel units, and shielding the upper portions of the dry channel units. The dry channel shield effectively prevents evaporation water sprinkled by the evaporation water supply unit from being introduced into the wet channels and simplifies the configuration of the evaporation water supply unit.
