Heat exchanger with coupling tube between two distribution tubes - has releasable wall abutting louvred wall in heat conductive manner

摘要

The heat exchanger consists of two distribution pipes, with intermediate parallel connections,. Both pipes sides carry a sheet metal shutter wall, with a third wall on another side. The third wall (6) is positioned directly on the shutter wall (5) and below it. It is in heat-conductive contact with it, and is also removeably fastened to the heat exchanger. - The third wall may be plane or shuttered. It has projecting beads (26) with rows of apertures (6') facing inwards. - The apertures in the rows (4'-6') of all three walls (4-6) are positioned, so that they eject air in the same flow direction.
