Abstract
An inductive air passage with a high fire resistance capability, that is easily paint coatable, and that can be economically produced, is made of die stamped sheet metal components. A slot-shaped inlet opening (1) is formed in a first sheet metal component and two outlet openings (2) are formed in a second sheet metal component. A baffle barrier (4) fits between the outlet openings (2). The two sheet metal components form plates (5, 6) and frames for the inlet opening (1) and for the outlet openings (2), respectively. One sheet metal plate (5) for the inlet opening (1) is provided with an I-shaped slit, whereby each of two curved lips (8) are produced by bending the lands formed by the I-slit toward one of the outlet openings (2). The other sheet-metal plate (6) has two U-shaped slits providing respective lands for forming tongues for defining the outlet openings (2). The tongues produced by the U-slits are angled toward the inlet opening (1) and toward the bent-over edges of the curved lips.
