Heat-exchanger with a circumferential circulation

摘要: L'invention concerne une structure d'echange d'energie amelioree, comportant des plaques (24,25) generalement paralleles, reunies pour delimiter un passage creux destine a l'ecoulement circulaire d'un fluide entre admission (13) et sortie (21), lesdites ondulees en croisee canaux opposes obliques se croisant, comprenant de multiples jeux paralleles disposition involutee desdits canaux. The invention relates to an improved energy exchange having plates generally parallel, combined define hollow for flow circular fluid between inlet and outlet said corrugated sheets cross-structure oblique opposed channels crossing, further comprising multiple sets of parallel involute arrangement channels.
