IMPROVEMENTS TO RADIATORS
The present invention relates to an improved radiator advantageously usable for heating domestic or industrial environments.

 Traditionally, the term radiator is understood, in the present context, a device capable of receiving a continuous flow of heating fluid, in particular hot water, and of transmitting to the surrounding environment a certain amount of heat transported by this fluid heating. The heating fluid, once it has cooled by passing through the radiator, is returned to the boiler where it undergoes a new heating, and so on until the user, or a thermostat connected to the heating installation, interrupts the continuous flow of heating fluid between the radiator and the boiler and vice versa.

 By way of example, without losing its general appearance, in the rest of the document, reference will be made to a radiator comprising at least one pair of vertical collectors and a plurality of parallel horizontal tubes which are substantially coplanar with each other. compared to others. This radiator further comprises means for supplying a heating fluid, means for evacuating said heating fluid and means for separating between the heating fluid entering the radiator and the heating fluid leaving said radiator.

 A radiator of this type is known from European patent application EP-A2-0 911 596 (N. V. VASCO).

 In this document is described a radiator of the aforementioned type, which comprises two vertical collectors and a plurality of horizontal tubes interposed between the collectors, which tubes make the structural and hydraulic connection between said collectors.

The supply of the heating fluid and its evacuation, once the heat exchange has taken place between the radiator and the surrounding environment, is carried out by means of a manifold block structurally and hydraulically connected to the lower horizontal tube.

 In particular, the inlet and outlet passage of the heating fluid, for example water, is carried out by means of a pair of openings hydraulically connected to the abovementioned collecting group. Of course, to separate the incoming heating fluid from the outgoing fluid, it is necessary to adopt separation means, which, according to a first

<Desc / Clms Page number 2>

 embodiment described in the aforementioned document, are made by means of a complete flattening of the wall on itself. In this way, the desired subdivision of the horizontal tube is obtained into two branches not hydraulically connected to each other.

 In a second embodiment, on the other hand, the separation between the two fluids, incoming and outgoing respectively, is obtained by placing a partition inside said lower tube.

This produces the desired hydraulic isolation between the fluid flows in circulation in the two branches in which the lower horizontal tube has been subdivided. Of course, the aforementioned supply opening is in the first branch while the discharge opening is formed on the second branch.

 The first solution envisaged in the aforementioned document has the major drawbacks that it harms the radiator from an aesthetic point of view, because of the flattening of a single tube which compromises the similarity of the latter with the other horizontal tubes, and that 'it gives the latter a plastic deformation capable of reducing its mechanical resistance.

 As for the second solution, it is difficult to carry out because it requires, as has been said, the insertion of a partition wall inside the lower horizontal tube by an operation which causes the increase, so even significant, the overall cost of manufacturing the radiator.

 The object of the present invention is therefore to produce a radiator of the aforementioned type which is free from the drawbacks described above, and which, moreover, entails relatively limited production costs.

 According to the present invention, there is provided a radiator comprising at least one pair of manifolds and a plurality of parallel and substantially coplanar tubes, the radiator further comprising means for supplying a heating fluid, means for discharging the fluid. heater and means of separation between the heating fluid entering the radiator and the heating fluid leaving it, said radiator being characterized in that the separation means are integral, at least partially, with supply means or means evacuation, or both.

 The present invention will now be described with reference to the accompanying drawings which illustrate a nonlimiting exemplary embodiment thereof, in which: FIG. 1 illustrates an overall view of a radiator according to the invention; 2 shows a side view, partially in section, of certain details belonging to the overall view shown in Figure 1; Figure 3 illustrates a plan view of certain details shown in Figure 2; and FIG. 4 represents, in perspective, a supply member or, indifferently, a member for discharging the heating fluid used in the radiator of the invention shown in FIG. 1.

 In FIG. 1, the reference 1 designates, as a whole, a radiator provided with a fixing member (not visible) to any wall (not shown). This radiator 1 is advantageously usable for heating domestic or industrial environments.

 The radiator 1 comprises a pair of manifolds 2,3 which, in the particular embodiment shown in FIG. 1, are vertical. These vertical collectors 2, 3 are structurally and hydraulically connected to one another in leaktight manner via a plurality of horizontal tubes 5. The horizontal tubes 5 are substantially identical to each other and each of them can have a circular section of constant diameter.

 The heating fluid, for example hot water, is supplied via a supply duct 6 provided with a tap 7 capable of regulating the flow rate of said heating fluid. As will be seen in more detail below, the supply duct 6 is hydraulically connected, on the one hand, to a first branch Sa'd of the lower horizontal tube 5a and, on the other hand, to the rest of the installation heating (not shown). To the second branch 5a "of said tube 5a, on the other hand, is hydraulically connected a duct 8 for evacuating the heating fluid through which this fluid is returned, in known manner, to the boiler (not shown) where it undergoes new heating .

 As still shown in FIG. 1, this evacuation duct 8 can be provided with a small valve 9 for exhausting the air contained in the heating fluid. In addition, between the supply duct 6 and the

<Desc / Clms Page number 4>

 evacuation duct 8 is interposed a separating wall 10 in order to separate the incoming and outgoing flows.

 As still shown in FIG. 1, the flow of heating fluid entering the radiator 1 takes place in the directions indicated by the arrows FI while the flow of the outgoing fluid is designated by the arrows F2. Consequently, the heating fluid, once it has passed through the branch Sa'd of the tube Sa, is distributed by the collector 3 to the remaining tubes 5, which structurally and hydraulically connect the collector 3 to the collector 2 which is parallel to it. Finally, the heating fluid, of course at a temperature below the inlet temperature, is first sent to the discharge conduit 8, but passing through the branch 5a "of the tube Sa.

 The assembly of the supply conduit 6, the evacuation conduit 8, the tap 7, the small exhaust valve 9 and the wall 10 constitutes a collecting group 11, which, as a whole, is structurally and hydraulically connected to the horizontal lower tube Sa.

 The innovative part of the radiator 1 which is the subject of the present invention is shown in FIGS. 2 to 4.

 As shown for example in Figure 2, at least one branch Sa ', 5a "of the tube Sa is associated with a member 12 which can be, indifferently, a member for supplying or discharging the heating fluid.

branche Sali, il fera en revanche office d'organe d'évacuation. In other words, if, for example, the member 12 is associated with the branch Sa ', this member 12 will act as a supply member. Similarly, if this member 12 is inserted into an opening 13 made in the

Sali branch, it will however act as an evacuation organ.

 Consequently, for the sake of convenience of presentation, reference will always be made below to said member 12 shown in perspective in FIG. 4 whether it is a supply member or a discharge member.

 This member 12 generally comprises a substantially cylindrical main body 14 with which a ring 14c is associated. The external diameter of the main body 14 must have the same nominal dimensions as the diameter of the opening 13 and have dimensional tolerances capable of allowing forced coupling between said main body 14 and the corresponding opening 13.

<Desc / Clms Page number 5>

 In the embodiment shown in the accompanying figures, the main body 14 and the ring 14c have been made in one piece.

 As still shown in FIG. 2, the main body 14 can preferably be subdivided into two parts 14a, 14b. The two parts 14a, 14b are cylindrical sectors and have been obtained by a single cutout 15. In particular, the part 14b must be provided with an external profile 16 which allows it to couple perfectly in leaktight manner with the profile of the internal wall of the branch Sa 'or of the branch Sa "on which the member 12 is mounted.

 In this way, it is the part 14b (FIG. 2) which will constitute the separating partition between the flow FI of the incoming fluid and the flow F2 of the outgoing fluid.

 As shown in Figure 4, the main body 14 has internally a thread 17 which allows the coupling of the member 12 with, respectively, the supply duct 6 or with the discharge duct 8, depending on whether this member 12 is associated respectively with the Sa'or branch or with the 5ardu tube Sa branch.

 It is also obvious that, traditionally, between the member 12 and respectively the conduit 6 or the conduit 8, a respective tubular connection device (not shown) with double thread must be provided, or more simply an inlet valve and an outlet valve.

Of course, one of the two threads of this connection device must be able to be screwed into the thread 17, while the other is used for coupling with, respectively, the conduit 6 or the conduit 8.

 To facilitate the coupling of a lower face 14d (FIG. 4) of the ring 14c with the external surface of the tube Sa, it is possible to provide, on this tube Sa, a flattened part 18 (Figures 2,3) on which this face 14d can be supported. The attachment of the member 12 respectively to the branch 5a 'or to the branch 5a "can be carried out with traditional systems such as, for example, a weld between the ring 14c and the flattened part 18.

 Even if, for the sake of convenience of presentation, the member 12 has been inserted into the horizontal tube Sa, it is however possible, without departing from the scope of the invention, to envisage a coupling of this member 12 with at minus one of the two collectors 2.3.

 In addition, as shown in more detail in Figures 2,3, it is possible to use a single member 12 of the type described above in

<Desc / Clms Page number 6>

 associating it with the opening 13 belonging to the branch Sa'or to the branch 5a ", while, for the remaining opening 13, it is possible to adopt any sleeve (not shown) possibly internally threaded, but which does not have a profile capable of constituting a separating partition between the two branches Sa ', 5a "of the tube 5a.

 Even if, in the embodiment described above, the ring 14c and its main body 14 were made in one piece, it is obvious that, without departing from the scope of the present invention, it is possible to provide a variant in which this main body 14 is made integral with the ring 14c by means of a weld. It is obvious, moreover, that part of the invention is any solution in which a partition between the flow of incoming heating fluid and the flow of outgoing heating fluid is made integral, by any system, respectively with a sleeve d 'supply or discharge.
