Abstract (en)

[origin: EP0374896A2] The invention relates to a flat tubular condenser for a vehicle air-conditioning unit, in which the coolant is led through flat tubes (2) subdivided into a plurality of ducts, and in cross-flow thereto ambient air is led along ribbed segments folded in a zig-zag or wavy fashion, individual flat tubes being connected in parallel in groups into the same coolant circuit through the condenser by manifolds (10) arranged at their two ends. According to the invention it is provided that the manifold sheath (62) is composed of two arcuate flat parts (66, 68) of Al or an Al alloy, which are mutually overlapping and are soldered to one another in the two overlap regions (64), that only one (the first) flat part (66) is provided with plug-in slots for receiving one flat tube (2) in each case, and that the first flat part is coated with solder for the purpose of soldering to the flat tubes and the second flat part. Furthermore, the invention relates to a method of producing the manifold sheath of a special embodiment of such a flat tube condenser, and applications. <IMAGE>
