Abstract

A parallel flow condenser having a plurality of substantially flat, parallel flow tubes are positioned between oppositely disposed headers. The flow tubes provide fluid communication between the headers for cooling fluid which flows through the condenser. Each of the headers is formed from an inner member having an inner wall and a pair of longitudinally extending, parallel sidewalls which protrude outward from the inner wall. The parallel sidewalls terminate in outer edges. An outer member is provided having an outer wall and a pair of longitudinally extending attachment flanges which project inward from the outer wall. The attachment flanges are positioned between the parallel sidewalls of the inner member with the attachment flanges overlapping and joining one of the parallel sidewalls so that the inner and outer members are effectively joined together to form a fluid passage. The inner edges are spaced apart from each other a distance less than the width of each of the flow tubes so that the ends of the flow tubes contact the inner edges of the attachment flanges, which act as stops, to prevent the tubes from being inserted too far into the openings of the inner wall of the header.
