摘要： A heat exchange cell includes a helically-shaped heat exchanger, in which a first heat transfer fluid circulates; a first heat exchange chamber in which a first collection chamber is defined; a second heat exchange chamber in which a second collection chamber is defined; and a fluid outlet passage from the second heat exchange chamber.
The first and second heat exchange chambers are separated by a first separating element comprising a substantially plate-shaped body and by at least a second separating element so as to define at least one passage of fluid between the first and the second collection chamber of the second heat transfer fluid.
A pair of axial separator baffles extend axially between the second separating element and the rear wall of the containment casing, and are configured to separate a first portion of the second collection chamber from a second portion of the second collection chamber.-

摘要： A heat exchange cell includes a casing, a heat exchanger in which a first heat transfer fluid flows, a feeding zone, and first and second collection chambers for a second heat transfer fluid. The casing can include rear, front, and peripheral side walls. The heat exchanger can be helically-shaped, mounted in the casing, and include at least one tubular duct for the flow of the first heat transfer fluid. The tubular duct can be coiled about a longitudinal axis and define a helix. The feeding zone of the second heat transfer fluid can be defined in the casing coaxially and internally with respect to the helix. The first chamber can be defined externally with respect to the heat exchanger by a radially outer wall thereof and the peripheral side wall. The second chamber can be at least partially delimited by at least one separating element.

摘要： A heat exchange cell is described comprising a containment casing (11) comprising a rear wall (11d), a front wall (22) and a peripheral side wall (11c), a helically-shaped heat exchanger (13) comprising at least one tubular duct for the flow of a first heat transfer fluid coiled about a longitudinal axis of the helix according to a plurality of coils and mounted in the containment casing (11); a feeding zone of a second heat transfer fluid, intended for the heat exchange with the first heat transfer fluid, defined in the casing (11) coaxially and internally with respect to the heat exchanger (13); a first chamber (15) for collecting the second heat transfer fluid externally defined with respect to the heat exchanger (13) between a radially outer wall thereof and the peripheral side wall (11c) of the containment casing (11); and a second chamber (16) for collecting the second heat transfer fluid at least partially delimited by at least one separating element (14). The separating element (14) is mounted at an axially external position with respect to the heat exchanger (13) in such a way as to define the second chamber (16) for collecting the second heat transfer fluid between the separating element (14), the peripheral side wall (11c) and the rear wall (11d) or the front wall (22) of the containment casing (11); in this way, the first (15) and the second (16) collection chambers are in fluid communication with each other by means of at least one passage (17a, 17a′, 17b-17g; 14e) configured to allow a flow of the second heat transfer fluid substantially in parallel to the peripheral side wall (11c) of the casing (11) and in proximity thereto. The separating element (14) comprises a heat exchange portion in contact with at least one portion of an end coil of the heat exchanger (13) and configured to allow a heat exchange between the coil-shaped portion of the heat exchanger (13) and the second collection chamber (16), while the heat exchange cell (10) further comprises at least one second passage (35) allowing a fluid outlet from the second collection chamber (16) peripherally defined in the second chamber (16) between an axial end (11g) of the peripheral side wall (11c) and the rear wall (11d) or the front wall (22) of the containment casing (11).

摘要： A heat exchange cell for a heating boiler includes a casing with a sidewall enclosing an internal space, the sidewall having an open front end surrounded by an annular edge of the casing front end. A sheet metal annular closing flange has an opening and radially internal, intermediate and external flange edges. The radially external flange edge connects to the casing sidewall along the annular edge. The radially internal edge defines radially internal and external surfaces. A front edge surface connects the radially internal surface and radially external surface. The front edge surface defines a lying plane on which the front edge surface lies, the lying plane defining an axial direction orthogonal to the lying plane and passing through the opening, and a radial direction orthogonal to the axial direction. The radially internal surface extends parallel to the axial direction protruding towards an outside of the cell.
