FIELD: heat engineering.
SUBSTANCE: invention relates to the field of heat engineering; it can be used in plate heat exchangers. Plate (20A) for a heat exchanger, intended for being placed in a stack of plates, contains: main panel (60) having first edge (67) and second edge (68) opposite to first edge (67), and at least one first rib (63) protruding from main panel (60) and made with the possibility of limitation, together with main panel (60) and an adjacent plate, of a fluid circulation tract, while first rib (63) passes from first edge (67) of main panel (60) towards second edge (68), without reaching second edge (68), to provide the first passage for the first fluid between one end of first rib (63) and second transverse edge (68), where the fluid circulation tract forms the first reflecting barrier. The invention also relates to a heat exchanger containing such a plate.
EFFECT: reduction in clogging and simplification of purification of a heat exchanger.
