- the two upper paths are facing and coaxial to each other and positioned at right angles to the third central lower path.
- the third central path is configured for coupling with the above-mentioned duct, so that the duct itself and the two heads at the relative ends form the base module.
- the coupling between the above-mentioned elements usually occurs by welding.
- the number of ducts of each module, as well as their shape, may vary as a function of both design and installation requirements: however, this does not entail any basic variations to the above-mentioned definition of the base module.

- the upper outer paths are closed by respective closing plugs, leaving open the ends intended for the inlet or outlet of the heating liquid.
- a drawback of this type construction consists in the undoubted slowness in the production of the radiant body, especially if the radiant body consists of a large number of base modules, since it is necessary to use many joining pieces; this requiring lengthy intervention times and precision in order to make a body with a perfect seal.
- a further drawback is due to the need to carry out, on the heads, machining which is particularly delicate and in need of precision, such as the above-mentioned inner threads of the first two paths of the heads themselves.
- the aim of this invention is to provide a radiant body which overcomes the above mentioned disadvantages of the prior art.

Description
- This invention relates to a radiant body and a method for making the radiant body.
- More specifically, reference will be made to a radiant body which can be used for heating rooms, especially areas for living or industrial use.
- Such a type of radiant body, which is usually applicable to a wall in a suspended fashion, is described, for example, in patent document
EP854347 - Another type of radiant body, which is usually applicable to a wall in a suspended fashion, is described, for example, in patent application document
WO 2007/012929 and comprises several base modules which are associated with each other to define the radiant body of the appropriate size for the volume of the room to be heated. The document reveals all the features of the preamble ofclaim 1. - Each module basically comprises: a tubular element mainly with longitudinal extension, internally hollow to configure a duct; a first head and a second head associable stably to the corresponding ends of the tubular element; each head comprises a body configured with a "T" shape internally hollow to form a 3-way passage channel.
- The two upper paths are facing and coaxial to each other and positioned at right angles to the third central lower path.
- The third central path is configured for coupling with the above-mentioned duct, so that the duct itself and the two heads at the relative ends form the base module.
- The coupling between the above-mentioned elements usually occurs by welding.
- The number of ducts of each module, as well as their shape, may vary as a function of both design and installation requirements: however, this does not entail any basic variations to the above-mentioned definition of the base module.
- To be able to proceed to the coupling of two or more base modules to define the radiant body of the desired size, one of the prior art solutions contemplate that both the heads, at the first two upper paths, are equipped with an inner thread: this is obtained by machining after the forming of the heads themselves, which, usually, are obtained by means of moulding. The outside faces of the heads, where there is the thread, are flat.
- For the connection between two adjacent modules, use is made of a joining element or piece (known to experts in the sector as "nipples"), which is also tubular, internally hollow, and provided on the outside with a double thread in opposite directions; an annular seal (O-Ring type) is positioned between the two threads which will act as a seal to the passage of fluid.
- The production of the radiant body therefore occurs by screwing, to the two heads of each module, corresponding connecting pieces with interposed the respective seal; the operation is then repeated for the second, third module and so on, up to the desired size. Lastly, the upper outer paths are closed by respective closing plugs, leaving open the ends intended for the inlet or outlet of the heating liquid.
- The seal between two consecutive modules is entirely entrusted to the seal which is pressed, following the assembly of the heads-joining piece, between the outer flat walls facing each other of the heads themselves.
- A drawback of this type construction consists in the undoubted slowness in the production of the radiant body, especially if the radiant body consists of a large number of base modules, since it is necessary to use many joining pieces; this requiring lengthy intervention times and precision in order to make a body with a perfect seal.
- A further drawback is due to the need to carry out, on the heads, machining which is particularly delicate and in need of precision, such as the above-mentioned inner threads of the first two paths of the heads themselves. The aim of this invention is to provide a radiant body which overcomes the above mentioned disadvantages of the prior art.
- More specifically, the aim of this invention is to provide a heating body which is able to allow a facilitated fitting of the elements making up the individual modules, thereby reducing the time needed for assembling and forming the heating body until obtaining the required dimensions.
- A further aim of this invention is to propose a method for making the radiant body which is able to assemble the radiant body very quickly.

- The radiant body according to any one of claims 4 to 7, wherein the first closing means (50) and the second means (51) for conveying a fluid are provided with contact surfaces or shoulders (50b, 51b), with a diameter larger than the diameter of the respective thread zone, to configure an abutment for the relative second and third seals (55, 56).
- The radiant body according to any one of the preceding claims, wherein each junction body (20, 21) defines a length module (L1) at least equal to the length (L) given by the sum of base modules (10) side by side predetermined to form the radiant body (1).
- The radiant body according to any one of the preceding claims, comprising at least one pair of tubular connecting elements (60) configured to connect to the pair of junction bodies (20, 21) in such a way as to modify the length of the junction bodies (20, 21) according to the maximum number of base modules (10) forming the radiant body (1).
- The radiant body according to claim 10, wherein each tubular connecting element (60) is equipped with threads (61) at the relative ends and with at least one radial hole (62) for passage of fluid.
- A method for making a radiant body according to any one of claims 1 to 11, characterised in that it comprises the following steps:- preparing a first base module (10);- inserting the corresponding junction bodies (20, 21) in the first and second head (14, 15), along the first two paths (16, 17), and in such a way as to position a corresponding opening (30) of each junction body (20, 21) inside the corresponding first and second head (14, 15);- inserting corresponding first seals (40) on opposite sides to the first and second head (14, 15);- inserting at least a second base module (10), alongside the first base module (10), inserting the respective first and second head (14, 15) in the corresponding junction bodies (20, 21) through the corresponding first two paths (16, 17) until obtaining a compaction of the two contiguous modules (10) and a flattening of a corresponding first seal (40) between the chamfers (14s, 15s) of the first or second heads (14, 15) and the outer surface of the junction bodies (20, 21);- associating, by screwing, first closing means (50) and second means (51) for conveying a fluid to the corresponding end of the junction bodies (20, 21) to close the assembly thereby made.
