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.
