Heat exchanger and casing for the exchanger

摘要

The exchanger has heat exchanging elements including air flow disturbing fins mounted in air flow tubes, and emerging into an air collection box (11). A collector (10) maintains the elements, and is maintained by a casing. The casing receives the elements, and the box is directly maintained by the casing. The box includes an end portion i.e. shoulder, having a shape complementary to that of an end of the casing, so as to ensure continuity of an outer surface of the exchanger. The box and the collector are maintained between a crimping lug (18) and a stop (20) of the casing.
