Abstract (en)

[origin: EP0767354A1] The heat exchanger has a collector plate (10) with a wall. The wall has apertures (18) to receive the ends of the heat exchanger tubes. The wall is shaped to form collets (24) surrounding the apertures, to which the tubes are brazed. The wall is made with thin sections (A) in a selected region (28) surrounding each collet. This allows axial movement of the collet relative to the rest of the plate under the effect of variations in tube length as a result of thermal expansion fluctuations. The thin sections of the wall follow the shape of the collets. Each collet is connected to the rest of the plate by an annular fold (26) with a U-shaped cross-section, having one side which forms the collet and the other the connecting pipe. The collector plate and the tubes are both made from aluminium. The thin sections are made by moulding or removing material from one or both sides of the plate.
