Blow-off incorporating apparatus for evacuating water and dirt from a cooler box of a cooling system

摘要

Apparatus for evacuating water and dirt from a cooler box of a cooling system, incorporated with a blow-off for an air screen of the system. The water and dirt will flow through an aperture in a lower region of the cooler box into a smaller box of the apparatus disposed therebelow. A fan operable for generating the air flow through the air screen and the cooler box, also blows a portion of the flow through a blow-off channel to the air screen for blowing debris away from the air screen. The channel and smaller box are cooperatively configured such that the air flow through the channel will generate a partial vacuum condition in the smaller box operable for evacuating the water and the dirt into the channel so as to be carried away with debris from the air screen.
