FIELD: heat exchange.
SUBSTANCE: disclosed is gasket (57, 57', 57'') of the through hole and assembly for heat exchanger (31). Gating of through hole is circular and is made with possibility of enclosing - within its inner periphery (58, 58') - area (43) of through hole of first plate and area (34) of through hole of second plate. First surface (60) of the passage orifice, which is arranged with the possibility of contact interaction with the first plate, is corrugated so that it borders interlocks (62) of the gasket and recess (63) of the gasket along the longitudinal extension (L) of the through hole laying. Plates of gasket and cavities of the gasket are arranged so that they are mated with cavities (49) of plate and flanges (47) of plate belonging to first plate. Second surface (61) of the through hole, which is arranged with the possibility of contact interaction with the plate-like structure containing the second plate, is, in fact, flat and is located with the possibility of contact with the substantially flat surface (38) of the plate structure.
EFFECT: technical result is simplification of design and higher efficiency of heat exchanger.
