Header box for heat exchanger

摘要

The box has a collecting plate (26) provided with reception openings (28) for inserting heat exchange tubes (18) and fluid inlet/outlet openings (34, 36). A sleeve (40) is arranged in one of the openings. The sleeve has a retention unit e.g. flange (42), cooperating with the plate (26) for maintaining the sleeve, where the sleeve receives fluid inlet/outlet tubes. The plate is stamped at the level of the openings to form a housing (38) of shape similar to the flange, where the flange is housed in the housing.
