AbstractThis disclosure deals with an air cooler and cleaner which receives compressed air coming from an air compressor and removes the moisture content, lubricant oil, solid particles and other contaminants which may be entrained in the air. The air cooler and cleaner includes a tubular metal housing, an upper housing closure and a lower housing closure. Sheet metal cooling fins having housing-receiving openings and cylindrical spacer and heat-conductor collars around said openings are heat shrunk onto the housing in firm thermally conductive contact therewith, the fins being in spaced relation to each other. A swirl chamber is provided in the lower portion of the housing and a cooling chamber is provided 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 is mounted 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 is mounted a short distance below the air director for separating the swirl chamber from the cooling chamber and has 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 is provided in the upper closure for the discharge of the cooled and cleaned air, and a filter is provided in the upper end of the tubular housing, through which the compressed air passes. A contaminant drain opening is provided in the swirl chamber and an automatic drain valve is connected with the drain opening.
