FIELD: heating.
SUBSTANCE: invention refers to heat power engineering and can be used at manufacture of tubular heat exchangers. A tubular heat exchanger for heat exchange between two fluid media includes housing (2), inside which one or more tubes (8) for the first fluid medium pass between inlet and outlet chambers (5, 6). The above tubes pass through openings (13) in baffle walls (11) fixed at some distance from each other by means of one or more fasteners. The fastener represents channel (14) fixed by being latched in one or more grooves (19) formed on the corresponding baffle walls (11). According to the invention, the above channel has a V-shape, and groove (19) has a V-shape with projections (23) on two of its opposite edges (22) so that V-channel (14) can be latched by being entering behind those projections.
EFFECT: simpler and lower cost of manufacture and installation of heat exchangers.
