Abstract (en)

[origin: EP0984237A1] The heat exchanger has two circuits (C1, C2) formed by inner (14) and outer (16) U-shaped channels, and feed and return pipes (50, 52) linked to the channels to deliver identical or different fluids (F1). The channels are bounded by facing pairs of plates (12) and are connected through apertures (28, 32); in a variant they are formed by U-shaped tubes.
