Aluminium alloy heating body

Abstract: A heating body to be used as a towel heater/drier and/or as a heating and decorating radiator comprising modular manifold segments (13, 15) aligned and fixed to one another by means of threaded fittings, and pipes fixed between each couple of manifold segments. The manifold segments (13, 15) are made in die-cast aluminium alloy, whereas the pipes or columns (12) are in extruded aluminium alloy, said pipes or columns (12) being fixed to the manifold segments (13, 15) before the in-line connection thereof, so as to form the composite heating body.

Description: The present invention relates to a heating body suitable for the realization of decorating radiators fitted with horizontal or vertical manifolds, as well as for being used as a towel heater/drier. At present, heating bodies or radiators are known which comprise, in accordance with the preamble of claim 1, two tubular manifolds and a plurality of pipes or columns having their ends fixed to said manifolds, and where each manifold includes modular manifold segments aligned and fixed to one another by means of threaded fittings, and each manifold segment is fixed to the ends at least one pipe or column, the manifold segments being made in die-cast aluminium alloy, whereas the pipes or columns are in extruded aluminium alloy, the pipes or columns being fixed to the manifold segments before the in-line connection of said manifold segments. A heating body of this type is known both commercially and, for example, from US-A-1 797 636. However, in the heating body on the market manifolds and pipes are made in steel and connected to one another by welding. Each manifold, comprises one piece only, whose length is chosen initially according to the dimensions of the heating body or radiator to be realized. Once the manifolds and the plurality of pipes have been assembled and welded, they form an only integral unit which can not be modified in capacity and shape. On the other hand, the heating body disclosed in the above cited document has two tubular manifold (or header) each of which is composed by a plurality of manifold sections or segments equal one another, and each manifold sections or segment is formed on one side with a single raised portion or branch having a central opening internally threaded to receive a threaded extremity of one pipe or column. In other words, this heating body is composable from individual sections and pipes but: each manifold is formed from a plurality of individual sections or segments; all the manifold sections or segments are equal; each pipe or column has each end directly screwed and connected to an individual manifold section or segment; all the sections or segments of are connected by an axially estending tie-rod; and when assembled, all the pipes o columns can be equally spaced apart, only, because they are attached to individual, equal manifold sections or segment. It is an object of the present invention to provide a heating body comprising tubular components and conceived in a modular constructive structure, but formed from at least two different manifold segments, which may be coupled and assembled on each occasion and in different number and configurations, thereby permitting easy and comfortable composition of a wide choice of heating bodies, which may function as towel heaters/driers or as decorating radiators. Such an object is achieved by a heating body according to claim 1. In the heating body of this invention, any component may be made of an aluminium-alloy such as die-cast manifold segments and extruded pipes or columns to be fixed between the manifolds. Further, these components allow an easier and more convenient assembly of heating body, and the manifolds, comprising several elements, do not require any welding but may be coupled by screwing, like traditional modular-element radiators. The invention will be further described with reference to the accompanying drawings, illustrated only by way of non-limitative example, in which: Figure 1 shows a first manifold segment, with three side branches; Figure 2 shows a second manifold segment, with two side branches; Figures 3 and 4 show two heating body elements obtained by using manifold segments as shown in Figures 1 and 2 respectively; Figure 5 shows an example of a composite heating body obtained by assembling several elements as shown in Figures 3 and 4; and Figure 6 shows a sectional view of a pipe or column coupled to a manifold-segment branch. According to the present invention, a heating body 10 including tubular elements comprises two composite manifolds 11 and a plurality of pipes or columns 12 having their ends fixed to said two manifolds. Each manifold 11 is realized starting with modular manifold segments, precisely with a first tubular segment 13 having a number x of side branches 14, and at least another tubular segment 15 having a number y - different from x - of side branches 16. Both manifold segments 13, 15 may be made in die-cast aluminium alloy. The number x of branches provided in the first manifold segment 13 may be - for instance - three; the number y of branches provided in the second manifold segment 15 may be, for instance, two. The branches 14,16 of the two manifold segments 13, 15 are preferably - but not necessarily - equidistant from one another; the branches provided in the first segment are distributed on the whole length thereof - see Fig. 1 - while the branches provided in the second segment cover only a part of its length - see Fig. 2. Both manifold segments 13,15 are provided with internal threaded portions 17 for in-line coupling thereof by means of threaded fittings (nipples) in the usual form, and with one or more external reference ribs 18, which permit alignment of the segments to be fixed to one another, and only one orientation of their branches 14, 16. On a level with each side branch 14, 16 of the manifold segments 13,15, a neck 14a, 16a is provided respectively, and a pipe or column 12 is mounted and fixed to each couple of coplanar necks provided in two segments equal and opposite to each other. As shown in Figure 6, one end of the pipe or column 12 is inserted in a neck 19, where it will be solidly fixed in a watertight manner, for example by using thermosetting epoxy resin. With two first opposite manifold segments 13 and a number x (three) of pipes or columns 12 fixed between the said two segments, it is therefore possible to obtain an element of heating body A as shown in Figure 3. Likewise, with two second opposite manifold segments 15 and a number y (two) of pipes or columns it is possible to obtain another element of heating body B as shown in Figure 4. Said two elements of heating body A and B constitute the basic modular elements for the construction of composite heating bodies according to the present invention. In fact, by simply connecting the manifold segments 13, 15 of a number of elements A, or of a number of elements B or of a number of elements A and B by means of threaded fittings (nipples), it will be possible to obtain a composite heating body 10 in any size and configuration according to requirements, which may be installed and employed as a towel heater/drier as well as a heating and decorating radiator.
