Description: OBJECT OF THE INVENTION The present specification refers to an improved convention radiator as defined in the preamble of claim 1. Such a radiator is known for instance from FR-A-2 045 747. The object is achieving the suitable heating of the area in which it is incorporated, internally provided with a coil obtained by harmonic deformation of a conduit, provided with profiled parts which can optionally be formed by a mono-block body, these being located on the surface of the tubular body constituting the profile on its inner area or hollow area, having parts also shaped by profiles on the ends of the coil and as a joining nexus of the profiles placed against each other on the two sides thereof, having a longitudinal opening in both the upper and lower areas through which the heat flow emerges to the outside, and having the pertinent connections to the tubular body constituted by the coil on the ends of the body of the radiator, which emerge in an ascending and descending vertical direction at opposite points. FIELD OF THE INVENTION This invention has its application within the industry dedicated to manufacturing heating apparatuses, especially heating apparatuses fed by any fuel or heating element, using a water circuit as a heat producing element. BACKGROUND OF THE INVENTION The applicant is the holder of Patent application number 8803694, "WATER HEATING SYSTEM", which discloses and claims a system which generates the heating of water through gas burners and especially intended for heating, incorporating a combustion chamber which is used in its entirety, and in which the heat exchange occurs in order to achieve increasing the performance. The invention has two water circulation circuits, one of which is constituted of two vertical and parallel tubes, one of them being intended for the water inlet, and the other for the water outlet, said tubes being horizontally interconnected by means of straight runs which have a smaller diameter than that of the tubes which they connect, with a second water circulation circuit formed from an inlet tube which is helically wound around the tubular assembly of the first circuit until reaching the upper area, where it continues in a helix, subsequently descending in a vertical outlet run, the invention being complemented with the pertinent control means and accessories for firing, gas circulation, water circuit, valving, etc.. The applicant is also the holder of Utility Model application number 9003141, "RADIATOR APPLIED TO HEATING SYSTEMS BASED ON WATER", which is constituted of a water circulation tube upon which a plurality of flat bars is arranged, among which there is a hollow tube (3), and with the object of producing a maximum contact between said water circulation tubing and the adjacent flat bars, as well as an exhaustive contact between said flat bars and the tubes which, since they are hollow, generate the hot air circulation or convection. The applicant is also the holder of Utility Model application number 9500186, "IMPROVED RADIATOR APPLICABLE IN HEATING SYSTEMS BASED ON WATER", which discloses and claims a radiator intended for enabling a substantially greater performance in comparison to the conventional ones, and characterized in that the contact tube, inside of which the water circulates adjacent to the hollow tubes and to several flat bars, has a reducer body or element on its ends with the object of reducing the inner diameter of the tube located in the heat generating area, there being a solid element incorporated inside the tube with the bigger diameter and coinciding with the areas adjacent to the hollow tubes and flat bars, which also reduces the dimensions of the tube in the inner area, forcing the circulation of the water carried through the general tube, achieving a greater friction and therefore a substantial increase of the heating power of the water passing through the inner area. The applicant is also the holder of Utility Model application number 9500836, "IMPROVED CONVECTOR RADIATOR", which discloses and claims a radiator having a hollow tube connected to a water circuit, inside of which, i.e. inside of the hollow cylindrical body, there is a resistor which raises the temperature of the water, thus achieving transferring the heating effect to the outside, enhanced by the adjacent parts constituting the gills. Although in all cases the substantial increase in the production of the heating capacity has been observed in comparison to conventional radiators, it is determined that in all cases, the obtained radiator has a plurality of elements requiring their fixing by different means, each one of them incorporated with marginal elements that imply an increase in costs and a suitable maintenance of the assembly. French Patent number 2,045,747 discloses a central heating radiator, characterized in that it is constituted of a steel tube coil upon which corrugated sheets or gills are resistance welded, on both parts or on only one side, these intended to increase the surface of the heat exchange with the air, being shaped, apart from that previously said, as an inside coil through which the hot water, produced by means of a boiler or the like, circulates, generating the passage of the heat through the inside of the external parts and causing the convection of the heated air inside the sheets. It has been clearly observed that it is a convective heater which has no resemblance whatsoever to the object of the invention described in this specification, as it is a completely different configuration. British Patent number 957,567 discloses a heat exchanger for its use as a heater for large spaces of the type which have a tubular element for carrying the heating fluid, the element being arranged on one side and close to a panel such that the heat driven to the panel, from the heating fluid, is distributed to the space which is going to be heated from one side of the panel at a distance from the element, a heat exchanger which includes a plurality of sections, each one with a reinforcement portion and flange means established such that the reinforcement portions of the sections form a frontal panel, and at least one tube for carrying the heating fluid, the tube being extended through holes in the flange means of the sections, and arranged with at least one substantial extension of its perimeter in direct relation to the heat conduction to the edges of the holes. It is again seen that there is a radiator of large dimensions which internally shows a coil provided with a water inlet and outlet and which generates the heating of the area where it is installed due to the heat originating from the fluid running through the coil. British Patent number 1,572,817 discloses a heating panel which comprises a plurality of elongated heat conductor plates with a transversal profiled section, each plate having first and second reinforcement portions on the sides which are opposite a flange portion, such that a "Z" shape is determined in the transversal section of the plate, the plates being placed together, face to face, with their longitudinal directions being parallel, and such that the first reinforcement portion of one plate abuts with the second reinforcement portions of an adjacent plate and the flange portions are generally on a common plane, the panel furthermore including one or more extensions of heating tubes which pass through openings in the first reinforcement portions of the plates and being adjusted with them in heat conduction. The existence of an invention of features similar to those previously mentioned is again seen, although of smaller dimensions. French Patent number 2,319,096, filed as a Certificate in Part, discloses and claims a heat exchanger, specifically for high power facilities. This invention is not related to the object disclosed and claimed in the present specification either since it incorporates a double coil placed in parallel, with a tube which feeds the two coils and a transversally placed tube for generating the evacuation of the previously heated fluid which passes through the inside of the two coils. French Patent number 1,923,928 discloses a convective heating apparatus or heat convector in which the heating fluid runs through banks of horizontal tubes connected in parallel, a feature which is not at all related to the object of the invention disclosed in this specification. The evident solution to the currently existing problems in this matter would be that of being able to have a convective heater which enhances the convective evacuation of the heat by using the heating capacity of the water passing through profiled bodies, in which the inner assembly or water circuit were significantly simplified, the assembly of auxiliary elements being eliminated and the circuit solely and exclusively acting as a heat generating element. However, to date, there is no knowledge of the existence of an invention which is equipped with the previously indicated suitable features. DESCRIPTION OF THE INVENTION The improved convective heater proposed by the invention is an evident novelty within its specific field of application since it incorporates, inside the radiator and as a basic element onto which the auxiliary elements are fixed, a coil which acts as a circuit shaped like a hollow tube, inside of which the hot water passes through, whose heat enhanced by the elements placed against the structure of the coil, which act as convectors, generates the evacuation of the heat produced by the coil to the outside, in collaboration with a conventional assembly which causes the temperature increase which is transmitted to the water incorporated in the circuit which the different coils incorporated in the radiators form a fundamental part of. More specifically, the improved convective heater object of the invention is constituted of a hollow tubular body, inside of which the water passes which is heated by a conventional source causing an increase in the temperature of the water, which passes through a circuit to which the radiators are connected that have the tubular body inside adopting the shape of a coil, having the connections on its ends for the hot water input and output inside the coil. By conventional means, a mono-block body is placed against and fixed to the coil, or several suitably placed and fixed bodies, shaped by hollow profiles of a metallic material, which have closed outer sides, and inside are shaped as a hollow tubular body that is longitudinally placed, having openings on its ends and, adjacent to the longitudinally placed hollow areas, similar areas but which lack the partition wall adjacent to the coil, i.e. areas which, from a frontal view, adopt the shape of a "U". On the ends of the coil which are smaller in width, tubular bodies with a smaller width than those previously mentioned are fixed, which have the general shape of a "U", having a fixation which coincides with the coil at its longitudinal opening. On their upper and lower side of the prism that they form, the profiles or adjacent mono-block body on the larger sides of the coil are separated by an opening of a width similar to the profile which acts as a dimensioning device or distancing body, obtaining air convection through the openings located on the upper and lower part. The coil has ends placed in a vertical direction for the pertinent connection. DESCRIPTION OF THE DRAWINGS In order to complement the description which is being carried out and with the object of helping to better understand the features of the invention, three sheets of drawings accompany the present specification as an integral part thereof, which, with an illustrative and non-limiting character, show the following: Figure 1 shows a side elevational view of the object of the invention relating to an improved convective heater. Figure 2 shows a view of the object shown in figure 1, as seen frontally. Figure 3 shows a plan view of the object shown in the previous figures. Figure 4 shows an A-B view of the object shown in figure 1. Figure 5 shows a C-D view of the object shown in figure 1. Figure 6 shows an E-F view of the object shown in figure 2. Figure 7 lastly shows a duly sectioned view similar to that shown in figure 2, with the object of visualizing the inner conduit shaped like a coil. PREFERRED EMBODIMENT OF THE INVENTION In view of these figures, it can be seen that the improved convective heater (1) is constituted of several similar bodies (2) and (2') adjacent to a coil (5) which has connections (6) and (6') on its ends for incorporating the parts which permit the fixation to the circuit transporting the hot water produced by conventional means, water which, upon passing through the inside of the coil (5), and in collaboration with the parts (2) and (2') which internally have tubular hollow areas (3) and semi-tubular hollow areas (3'), achieve that the flow of hot air obtained by means of the coil in collaboration with the parts (2) and (2') goes to the outside, through the upper openings existing between the longitudinally positioned parts (2) and (2') in the upper and lower area of the convective heater (1), apart from the parts (2) and (2') being shaped, due to their metallic nature, as recipient parts of the heat produced by the coil (5), which also passes to the atmosphere of the area where the radiator (1) is located. As can be seen in the figures, the intermediate sides of the prism formed by the radiator (1) have locking parts (4) and (4') formed by profiles which, when seen frontally, adopt the shape of a "U", and which are placed against the surface of the ends of the coil (5), specifically on the protrusions which have the connections (6) and (6') through which the hot water passes to the inside of the coil (5). Subsequently, the hot water produces the heating of the parts (2) and (2') and these, due to their tubular (3) and semi-tubular (3') shape, produce a flow of air which goes outside through the previously described openings. The generating source for heating the water which passes through the coil (5) can use any type of fuel, and it can have any shape. It should be pointed out that the inner spaces of the parts (2) and (2') adjacent to the coil (5) can have similar or not similar dimensions.

Claims: Convection radiator (1) having a serpentine (5) predominantly extending in alongitudinal direction with connecting pieces (6,6') at its ends for connecting the serpentine to an external circuit, two metallic side walks (2, 2') adjacent to the surface of the coil (5) connected to it by conventional means and having upper and lower sides at their upper and lower ends in a vertical direction, the two metallic side walls (2,2') having internal conduits (3, 3') extending in the vertical direction; said conduits being separated a distance from each other defining a gap, this gap having essentially the same width as the serpentine (5), characterized in that the conduits (3,3') have tubular (3) and semi-tubular (3') forms; and in that profiles (4, 4') are inserted in the said gap covering it at the upper and lower ends of the metallic side walls (2,2'), said profiles (4, 4') having a "U" form.
