Plate heat exchanger with 3D fluid circulation

Abstract

Heat exchanger (1) comprising: - first (13) and second (15) heat exchange modules comprising first (21) and second (23) fluid circulation systems, - separation plates (19) sandwiched between first (13) and second (15) heat exchange modules, each fluidically disconnecting the first and second fluid circulation systems, at least one of the heat exchange modules comprising: a stack (50, 72, 115) of plates of shape (43, 73, 117) superimposed along a longitudinal axis (X) and each consisting of at least one through-cut zone (47, 93, 123) and a surrounding solid zone (49, 81, 121) of constant thickness, the corresponding fluid circulation system (21, 23, 50) being defined by the cut-out zones of the stack and extending between the adjacent separation plates, at least a portion of the zone hollowed out from one of the shape plates being superimposed on a solid area of ​​another adjacent shape plate, and vice versa.Figure for the abridged version: Fig. 8.
