With reference to Figure 1, a radiator element 1 for heating buildings has a base body 2 made of metallic material, in particular aluminum and, for example (but not necessarily) cast aluminum; the body 2 is a hollow body, which comprises a substantially tubular main portion 3 that extends longitudinally along the main X axis, which, with reference to the normal position of use of the element 1, is substantially vertical; the element 1 is provided with an internal chamber 4 for the passage of water and the transverse connection sleeves 5 for connecting with other radiator elements, and / or with a hydraulic circuit.

The body 2 has a front heat exchange plate 6 basically facing when in use the environment to be heated, and a rear heat transfer plate 7, opposite the front plate 6; the plates 6, 7 extend longitudinally along the respective Z axes parallel to the X axis and are substantially parallel to each other; the plates 6, 7 are connected to the main portion 3 by means of the respective longitudinal central ribs 8 (only one of which is visible in Figure 1), which are arranged basically in the middle plane of the element 1, extend radially from the main portion 3, and are substantially orthogonal to the plates 6, 7.

The element 1 also has two opposite sides 9 (only one of which is visible in Figure 1), which have opposite side surfaces 10 respectively: in a non-limiting example illustrated in Figure 1 (but not necessarily), the lateral surfaces 10 are defined by the respective lateral surface portions of the main portion 3 and by the respective faces of the ribs 8.

The plates 6, 7 are delimited by the respective pairs of opposite longitudinal side edges 11 and by the respective pairs of opposite faces 13, 14, for example, (but not necessarily) substantially flat and parallel; in particular, each plate 6, 7 has an internal face 13, facing the other plate, and an external face 14 opposite the internal face 13.

In the non-limiting example illustrated in Figure 1, the plates 6, 7 are substantially orthogonal to the middle plane of the element 1 and have a generic quadrilateral shape (in particular, substantially rectangular); the understanding is maintained that one or both of the plates may have a different shape from the one described purely by way of example, this being possible, for example, to have faces that are curved, wavy, etc., and / or rounded , oval, etc.

The back plate 7 is formed by means of a plurality of plate portions 17, to be precise at least three and preferably four or more, arranged in a coplanar manner and aligned in succession along the Z axis (parallel to the X axis); the plate 7 has a plurality of cuts 18, which are formed orthogonally passing between the faces 13, 14, are arranged in succession along the Z axis and axially spaced apart along the Z axis, and delimit a plurality of portions 17 plate.

In particular, the plate 7 has at least a series of three or more (preferably four or more) cuts 18 and / or openings, which are arranged successively along the Z axis and delimit at least three (preferably at least four) plate portions 17 arranged in a coplanar manner and aligned parallel to the Z axis; each portion 17 of the plate is delimited axially by a pair of consecutive cuts 18 along the Z axis.

At least two cuts 18 of the series are configured in a central area of the plate 7; "Central area" of the plate 7 is the area of the plate 7 that is configured on opposite sides of a transverse middle surface, perpendicular to the Z axis intersecting the plate 7 halfway up along the Z axis of the plate 7, and having a height (measured along the Z axis) equal to at least half of the total height of the plate 7 (again measured along the Z axis).

The central area includes at least two plate portions 17.

In the example illustrated in Figure 1, plate 7 has two series of cuts 18 configured side by side; cuts 18 of the two series face each other; pairs of cuts 18 of the two series are aligned in a transverse direction (perpendicular) to the Z axis. The cuts 18 of each series are substantially aligned parallel to the Z axis.

Preferably, each series is formed by at least four cuts 18 successively configured along the Z axis and axially spaced apart along the Z axis, which delimits at least four plate portions 17 arranged in a coplanar manner and aligned in parallel with the Z axis.

Here and in the following, the term "cut" is used to indicate a generic opening formed by passing through a plate between the opposite faces of the plate, regardless of its method of production, its shape, etc .; the cuts may have in particular any shape and are delimited by open perimeter edges (eg, indentations).

The plate 7 has elongated cuts 18 substantially transverse to the Z axis.

Preferably, but not necessarily, the cuts have a width smaller than the length (where the width is understood as being measured parallel to the Z axis, and the length is understood as measured in a direction perpendicular to the Z axis).

Each plate portion 17 has an internal surface, facing the body 2 and the front plate 6, and an external surface, opposite the internal surface, respectively formed by means of the respective portions of the faces 13, 14 of the plate 7.

In the embodiment of Figure 1, each cut 18 extends between the opposite side edges 11 of the plate 7 and crosses the plate 7 completely in a transverse direction, separating the plate portions 17 from each other.

The plate portions 17 are mechanically supported by the rib 8, which, in the example illustrated, extends substantially over the total length of the plate 7 and also connects the plate portions 17 to each other; the plate portions 17 are fixed on a front edge 19 of the rib 8 through the respective internal surfaces and extend in the form of a medulla from the front edge 19: in other words, the front edge 19 of the rib 8 is configured back with respect to the outer surfaces of the plate portions 17 and is not coplanar with them.

Alternatively, the plate portions 17 are delimited by pairs of opposing cuts 18, which extend from the respective mutually opposite side edges 11 and are separated by a central knot or connection portion, coplanar with the plate portions 17, the which connects the plate portions. In this case, the knot is aligned with the outer surfaces of the plate portions 17.

In any case, the lateral edges 11 of the plate 7 are discontinuous, being interrupted by the respective pairs of cuts 18 configured along the lateral edges 11; each of the lateral edges 11 is interrupted in at least three, and preferably four or more, longitudinal positions.

In the example illustrated in Figure 1, the front plate 6 is constituted by means of a flat continuous sheet, without, that is, cuts, for example, substantially rectangular, which has substantially straight lateral edges 11 without interruptions; it is still understood in any case that also the front plate 6 can be formed by the plate portions 17 as the back plate 7, as illustrated in Figure 2, in which precisely the front plate 6 and the back plate 7 are formed by means of the respective pluralities of plate portions 17 delimited by the respective pluralities of cuts 18.

In the example of Figure 2, the plate portions 17 of the plates 6, 7 are delimited by opposite pairs of cuts 18: the cuts 18 of each pair extend from the mutually opposite side edges 11 and are separated by a central knot or a connection portion 20, coplanar with the plate portions 17; the connection portions 20 are advantageously formed by means of the respective appendages of the rib 8 and are substantially aligned with the external surfaces of the plate portions 17.

It is then understood that only the front plate 6 can have the cuts 18 delimiting the plate portions 17, and the rear plate 7 can be constituted by a continuous sheet. In general, at least one between the front plate 6 and the back plate 7, or else of both plates 6, 7 is formed by means of pluralities of plate portions 17.

As illustrated in both Figure 1 and Figure 2, the radiator element 1 also advantageously comprises a plurality of luminous fins 25, which extend from the body 2; in particular, the element 1 comprises two sets 26 of opposite fins 25, preferably symmetrical, which extend from the respective lateral surfaces 10 of the sides 9.

The fins 25 extend basically in a longitudinal direction along the sides 9, for example, substantially orthogonal to the median plane of the element 1, and / or substantially orthogonal to the lateral surface 10 of the side 9 from which they extend.

Each fin 25 is defined by means of a substantially flat sheet; the fins 25 are substantially flat and parallel to each other and to the plates 6, 7 (but they could also be curved or have other figures). Each fin 25 extends substantially between two longitudinal ends of the body 2, without interruptions.

In the variation illustrated in Figure 3, the fins 25 are arranged in rows 27, which extend along the respective axes A substantially parallel to the X axis.

Each row 27 is formed by a plurality of fins 25 (at least two and preferably three or more fins) aligned along the respective axis A and separated by a respective series of notches 28; the fins 25 of the adjacent rows 27 are staggered with respect to each other in a direction transverse to the axes A, or rather at least some fins 25 of each row 27 at least partially face the respective notches 28 of the rows 27 adjacent.

Preferably, each assembly 26 comprises three, four or more rows 27 of fins 25 configured in a staggered manner; each row 27 has fins 25 staggered with respect to the fins 25 of the adjacent row (s) 27.

In the embodiment illustrated in Figure 4 and 5, the back plate 7 (and / or the front plate 6, even though in Figure 4 this is represented as a continuous sheet) has wavy side edges 11, it is provided with a respective series of cuts 18 that follow each other along the side edges 11 and are formed to define the respective concave concavities at the side edges 11.

In particular, the plate 7 has opposite pairs of cuts 18 (in particular, at least two and preferably at least three pairs of cuts 18), which extend from the respective side edges 11 of the plate 7 towards each other ( unbound) and delimit three or more plate portions 17 arranged successively along the Z axis.

Each pair of cuts 18 is formed by means of two opposite U-shaped or V-shaped cuts 18, optionally delimited by rounded edges, and are separated by a central node or a connection portion 20 connecting two portions 17 of consecutive plate.

Preferably, the cuts 18 formed on each side edge 11 are aligned with the respective cuts 18 formed on the opposite side edge 11; alternatively, the cuts 18 formed in the two lateral edges 11 are staggered.

The connection portions 20 are arranged in a coplanar manner with the plate portions 17 and have respective front surfaces aligned with the external surfaces of the plate portions 17, together with which they form the outer face 14 of the plate 7

Because of the presence of the cuts 18, the connecting portions 20 have a transverse width (measured perpendicular to the Z axis on the outer face 14, or between the vertices of the cuts 18 of each pair of cuts) smaller than that of 17 portions of plate.

Also in this embodiment, the element 1 advantageously comprises fins 25 arranged in rows and staggered in a transverse direction.

In this case, the rows 27 of fins 25 are constituted by the respective corrugated sides 29 which extend along the respective axes A; each side 29 has successive ridges and troughs that define, respectively, fins 25 and notches 28. Also in this embodiment, fins 25 of adjacent rows 27 (or rather of adjacent sides 29) are at least partly staggered in a transverse direction to the A axes; for this purpose, the sides 29 are shaped and arranged so that the ridges and troughs of the adjacent sides are staggered in a direction transverse to the axes A.

Finally, it is still understood that additional modifications and variations can be made with the radiator element described herein and illustrated, without departing from the scope of the appended claims.
