Definitions

the present invention relates to the building heating systems sector in general, and particularly concerns a plastic modular radiator element complete with a heat-carrier fluid flow distributor element.
heat emitter is used, in accordance with the standard UNI EN 442, to mean a device having the purpose of releasing heat so as to obtain specific temperature conditions in a building
radiationator is used, again in accordance with the standard EN 442, to mean a heat emitter that emits heat by natural convection and irradiation, manufactured and sold in modular elements of identical dimensions that can be assembled in "batteries” to form an assembly providing the desired total thermal output.
modular radiator elements are now generally made by molding and/or extrusion of various metal materials (steel, aluminium alloys, extruded aluminium, cast iron, copper) and consist of tubular vertical elements (hereinafter called “branches") of variable number that converge above and below on a coupling, in the form of a horizontal portion of duct, also called a "hub".
branches tubular vertical elements
Several modular elements are combined together to form a battery (or radiator), defining a hydraulic circuit consisting of a top hub and a bottom hub (resulting from the connection of the couplings of the various modular elements) that are in communication with each other by means of a plurality of vertical columns or ducts or branches.
the resulting radiator battery is connected to a heat-carrier fluid distribution system by means of specific inlet and outlet flow control valves, through which the fluid is delivered to a first hub in the battery, respectively called top or bottom hub, consisting of a horizontal duct from which the vertical branches of the radiator depart, the latter providing the connection to a second hub, respectively called bottom or top hub.
the radiator elements are hydraulically connected in parallel by the top and bottom hub and, given the manufacturing technologies used (which depend on the metal materials involved), the cross sections of the radiator branches - added together and placed in relation to the fluid flow rates through them - are comparable with the cross section of the hub. That is why any pressure drop of the fluid moving through a branch is much the same as the pressure drop through the hub. This gives rise to uneven heat-carrier fluid distributions that negatively affect the operation and thermal output of the radiator.
the object of the present invention is to provide a radiator for building heating systems characterized particularly by a light weight, adaptability to the space in which it is designed to operate, strength, insensitivity to stray and/or parasite currents (which tend to corrode the inside of the radiators) and to any agents that might corrode its outside surface.
a further object of the present invention is to provide a radiator of the above-mentioned type that is less complex and more cost-effective to manufacture and assemble in batteries.
Another object of the present invention is to provide a radiator of the above-mentioned type in which the fluid flow is evenly distributed so as to result in uniform pressure drops and equal thermal outputs for each element or module.
the numeral 1 is used to indicate the heat-carrier fluid distributor for a modular building heating radiator element consisting of a generically four-sided plate 2 and, more precisely, substantially rectangular, delimited by a perimetrical edge 3 orthogonal to the plate.
said edge 3 has four nozzles 4 with holes 5 in the middle (figure 4).
a through sleeve 6 is also connected perpendicularly to the plate 2, projecting from both sides thereof.
the sleeve 6 is situated about halfway along the edge opposite the nozzles 4 and terminates on one side with a tapered, narrower portion 7, the outer diameter of which substantially coincides with the inner diameter of the sleeve 6 before said tapering.
the plate 2 can be composed of two plate portions, coupled and molded so as to define four channels 8 which, after joining the two plate portions, give rise to a corresponding number of tubular ducts that place the sleeve 6 in communication with the nozzles 4.
the plate 2 with the edge 3, the nozzles 4 and the sleeve 6 are molded in a single piece.
the distributor can consist of the edge 3, acting as a supporting frame, the nozzles 4 and the sleeve 6 connected to the edge 3 and communicating with the nozzle 4 via radial ducts 8, all molded in a single piece.
the modular radiator element consists, in the example of an embodiment illustrated in figure 7, of four parallel radiator branches 9 and two heat-carrier fluid distributors attached to the respective ends thereof.
Said branches are lengths of piping that, being connected at the top and bottom to the distributors by means of the nozzles 4, place the top and bottom sleeves 6 in communication with one another.
figure 8 shows the hydraulic circuit of a battery of nine modules or elements.
a heat-carrier fluid inlet A which in this figure is situated at the bottom, and a corresponding outlet L are shown therein.
the various vertical lengths represent the single modules, while the two horizontal sections (AI and LT) represent the top and bottom hubs.
the letters indicate the top and bottom joints between each module and the two hubs.
each of the hydraulic circuits of figure 8 (A-L, A-B-M-L, A-B-C-N-M-L, and so on) connecting the fluid inlet A to the outlet L carries the same fluid flow rate, thereby ensuring an even thermal output from the single radiator elements.
a particularly preferred embodiment for achieving the objects of the invention involves making the modular element out of a plastic material, e.g. polypropylene, such as a polypropylene random copolymer (PP-R), with or without reinforcing fibers, or a polyester.
the plastic material used is characterized by a thermal conductivity of at least 0.15 W/m°K and a thermal dilation coefficient of no more than 3.5.10 -5 °K -1 , can be injection molded or extruded with a reflecting surface finish, can be heat-welded, has a useful working temperature of at least 90°C, and can withstand a working pressure of at least 3.5 bar.
joining the various component parts of a modular element, and joining several modules together to form a radiator can be done economically and with a limited energy absorption by heat-welding the plastic using Teflon-coated aluminium calibrators or templates of suitable dimensions heated to the melting temperature of the plastic raw material.
Teflon-coated aluminium calibrators or templates of suitable dimensions heated to the melting temperature of the plastic raw material it is sufficient to insert the parts to weld (for spigot and socket joints) or rest them (for end-to-end joints) against the calibrators for a suitable time and then apply a certain pressure. Then it is sufficient to simply extract (spigot and socket joints) or separate (end-to-end joints) the parts and place them in contact with one another for an established time interval under an adequate contact pressure, as a function of the material being used, in order to achieve a permanent joint.
the raw material used makes it unnecessary to provide for any surface treatments to protect either the inside (against stray and/or parasite currents) or the outside (against rust or magnetic pollution).
lighter-weight elements approximately 60% lighter than steel or aluminium and 80% lighter than cast iron
the hardness and stiffness of the raw material used in this invention are lower than those of the metal materials normally used, thus reducing any damage caused by accidental shocks.
the raw material used in this invention also adapts to the use of all the standard accessories for completing a battery of radiators.
the raw material identified drastically reduces the noise levels due to the fluid flowing in poorly-dimensioned systems, especially in the case of radiators made of extruded and die-cast aluminium.
