ABSTRACT:
An air cooler and cleaner for cooling compressed-air coming from an air-compressor and for removing the moisture content thereof and for removing lubricant oil and solid particles and other contaminants which may be entrained therein. The air cooler and cleaner includes a tubular aluminum housing and an upper housing-closure and a lower housing-closure. Sheet-aluminum cooling fins having housing-receiving openings and cylindrical spacer and heat-conductor collars around said openings heat-shrunk onto the housing in firm thermally-conductive contact therewith and spacing the fins in relation to each other. A swirl-chamber in the lower portion of the housing and a cooling-chamber in the upper portion of the housing. The swirl-chamber has a tangential air-inlet for rapidly spinning the air therein. An inverted cylindrical cup-like air-director within the cooling-chamber for directing the air against and along the wall of the cooling-chamber in a thin layer. A funnel-like member including a flange a short distance below the air-director for separating the swirl-chamber from the cooling-chamber and having a central opening and an air-riser-tube extending down from said opening into the swirl-chamber to a substantial depth thereof. An air-outlet port in the upper closure for the discharge of the cooled and cleaned air. A filter in the upper end of the tubular housing, through which the compressed-air passes. A contaminant drain-opening in the swirl-chamber and an automatic drain-valve connected with the drain opening.
