Abstract
Description
- The present invention relates to a radiator with radiating plate having high efficiency.
- In particular hereafter reference shall be made to radiators manufactured by means of a thick plate of thermally conducting material, e.g. aluminium, in which is obtained a groove (typically by milling) and, into said groove, is inserted a tube for conveying heat-carrying fluid.
- Currently, radiators of the aforesaid type present a structure provided with two manifolds; a first manifold is positioned at the lower area of the radiator (when the radiator is installed) whilst a second manifold is positioned at the upper area of the radiator.
- The plate is provided with vertical grooves positioned between the two manifolds and with tubes (typically made of copper) that are inserted in the grooves and that have the ends that project from the grooves and are connected by welding to each of the manifolds.
- Alternatively, the radiator is provided with a single manifold (presenting both the inlet and the outlet of water as heat-carrying fluid) and, therefore, it is provided with one or more tubes and grooves (or also multiple tubes and grooves) that fold in "U" shape in order to present both ends connected to the single manifold.
- The structures of the traditional radiators described above, however, present some drawbacks.
- The structure with two manifolds requires the manufacture of numerous welded joints to connect each tube to each manifold; this requires long production times and the use of a lot of specialised labour, with consequent costs that are very high.
- Moreover, both the structure with one manifold, and the one with two manifolds present a limited contact surface between tube and plate; this severely limits the heat exchange capacity between the tube (which contains the hot water that constitutes the heat-carrying fluid) and the plate (which heats the space in which the radiator is positioned); in practice, the ability of the radiator to heat the spaces is limited.
- An additional drawback of the traditional radiators described above is constituted by the fact that, in particular for plates whose shape is not squared, the tube and the groove cannot cover the entire surface; therefore, the edges, in particular the most irregular ones, are not adequately heated by the heat-carrying fluid with a consequent limitation of the heating power of the radiator.
- Lastly, in particular the radiators with single manifold present considerable problems with venting the air that is introduced in the tube, because it can remain trapped at the curves of the "U" shaped tubes.
- The technical task of the present invention, therefore, is to provide a radiator with radiating plate having high efficiency that makes it possible to eliminate the aforesaid technical drawbacks of the prior art.
- Within this technical task, an object of the invention is to provide a radiator with radiating plate that has a limited number of welded joints, in order to reduce production times and use of specialised labour, with the purpose of limiting production costs.
- Another object of the invention is to provide a radiator with radiating plate that presents a contact surface between tube and plate (through the walls of the groove) that is very high, in order to increase the heat exchanges between the tube and the plate relative to traditional radiators.
- An object of the invention is also to provide a radiator with radiating plate in which the tubes and the grooves are able to cover the entire surface of the plate, even at lateral edges of non squared and/or irregular plates, in order to optimise the heat exchange between the heat-carrying fluid and the plate.
- An additional object of the invention is to provide a plate radiator in which it is very simple and fast to vent the air that remained trapped within the tube, also for radiators with single manifold.
- The technical task, as well as these and other purposes, according to the present invention are achieved by providing a radiator with radiating plate having high efficiency as claimed in
claim 1. - Other characteristics of the present invention, moreover, are defined in the subsequent claims.
- Additional characteristics and advantages of the invention shall become more readily apparent from the description of a preferred but not exclusive embodiment of the radiator with radiating plate according to the invention, illustrated purely by way of non limiting example in the accompanying drawings, in which:
-
figures 1 and 2 show a view of a radiator according to the invention with rectangular radiating plate respectively with one and with two manifolds; -
figures 3 and 4 show a view of a radiator according to the invention with oval radiating plate respectively with one and with two manifolds; -
figure 5 shows a manifold according to the invention; and -
figure 6 shows a sectioned detail of a plate at the tube and the groove. - With reference to the aforementioned figures, a radiator with radiating plate having high efficiency indicated in its entirety with the
reference number 1 is shown. - The radiator 1 (
figure 1 or3 ) comprises a plate 2 (typically made of aluminium) which bears, at its rear side (when the radiator is installed) amanifold 3, (typically made of aluminium or copper or stainless steel or carbon steel) whereto is fastened (in the example shown) a tube 4 (made of copper, aluminium or stainless steel or carbon steel) for conveying a heat-carrying fluid. - The
plate 2 has a groove 6 (obtained in theplate 2 e.g. by milling) into which is inserted thetube 4. - The
tube 4 presents (figure 6 ) its (outer) surfaces positioned in direct contact with the surfaces of the groove 6 in which it is inserted, without the interposition of glues; this makes it possible to make very efficient the heat exchange between the heat-carrying fluid contained in thetube 4 and theplate 2. - Alternatively the
tube 4 is connected within the groove with the interposition of a glue. - The edges of the groove 6 are converging at its own portion open outwards.
- The
tube 4 is inserted in the groove 6 by pressure and, preferably, by rolling. - This allows to insert each
tube 4 into the groove 6 without the tube being able to exit from the same groove 6 and, in addition, it allows to deform the surface of thetube 4, making it adhere to the surfaces of the groove 6. - In this way the retaining of the
tube 4 in the groove 6 and the heat exchange between the heat-carrying fluid contained in thetube 4 and theplate 2 in which are obtained the grooves 6 are further improved; moreover, thesurface 4a that faces the exterior of thetube 4 has its profile aligned with theprofile 2a of theplate 2. - The
tube 4 and the groove 6 have at least onecoil portion 11 defined by a plurality offirst segments 12 substantially parallel to each other and able to assume substantially horizontal position when theradiator 1 is installed, andsecond segments 13 interposed between saidfirst segments 12. - The
coil portion 11 allows densely to cover theplate 2. - Advantageously, the
coil portion 11 of thetube 4 and of the groove 6 is at the delivery of heat-carrying fluid of themanifold 3 and thefirst segments 12 of thetube 4 and of the groove 6 are rectilinear. - In the example shown in
figures 1 and 2 , thefirst segments 12 of thecoil portion 11 of thetube 4 and of the groove 6 all have the same length, however other configurations are also possible and sofigures 3 and 4 show an embodiment of the radiator according to the invention in which thefirst segments 12 of thecoil portion 11 of thetube 4 and of the groove 6 have mutually different length. - In different embodiments, the radiator may have one or two manifolds.
- In the case of a radiator with a single manifold (
figures 1 and3 ) themanifold 3 is positioned at the lower portion of theradiator 1 when theradiator 1 is installed and thecoil portion 11 of thetube 4 and of the groove 6 develops upwards. - Moreover, at the upper end (when the radiator is installed) of the
coil portion 11, opposite the one where themanifold 3 is fastened, is fastened an air venting valve 15 (typically made of aluminium or copper or stainless steel or carbon steel). - Hence, the radiator presents a
tube 16 and a corresponding return groove, which are interposed between thevent valve 15 and themanifold 3. - Said
tube 16 and corresponding return groove are substantially rectilinear or present two or more substantially rectilinear portions or, alternatively, they can be curved or coil shaped. -
Figures 2 and4 show two examples of radiators with two manifolds (an upper one and a lower one). - In this case the
tube 4 and the groove 6 defining thecoil portion 11 extend from the lower area of theplate 2 and thetube 4 is fastened both to thelower manifold 3 and to anupper manifold 18, which also bears thevent valve 15. - Conveniently, the manifold 3 (in the case of single manifold) or both
manifolds 3, 18 (in the case of two-manifold radiator) has parallelepiped shape and it is made of aluminium, copper or stainless steel or carbon steel, such as to favour the connection, mechanical or welded, to theplate 2 without using hooks, punches or other devices; hereafter reference shall be made only to themanifold 3 but the manifold 18 (when present) has the same structure. - The
manifold 3 has two through holes delimited bycylindrical elements 20 projecting longitudinally, to which is fastened the tube 4 (or, when necessary, the vent valve 15). - This connection is typically achieved by welding, fitting the
tube 4 over or under theelement 20 and, then, performing the welding operation; thus, the presence of thecylindrical elements 20 is favourable to the welding, in particular when thetube 4 is made of copper whilst themanifold 3 is made of aluminium. - Naturally, other connection systems are also possible, e.g. the threaded connection which can be accomplished threading the
elements 20 and/or the ends of the tube 4 (threads meshing together or self-threading). - Moreover, the
manifold 3 is provided with threadedunion fittings 21 for the connection to the heating system of the building in which the radiator is to be installed or to receive appropriate plugs. - The operation of the radiator with radiating plate according to the invention is readily apparent from what is described and illustrated above and, in particular, it is substantially as follows.
- In the embodiment with single manifold, the heat-carrying fluid (hot water coming from the heating system of a building) enters the
manifold 3 through a union fitting 21 and, passing through acylindrical element 20, it passes into thetube 4. - Then, circulating in the
tube 4, it heats theplate 2, it flows through thevent valve 15 and, through thetube 16, it returns into themanifold 3 and it is expelled therefrom through the other union fitting 21 into the pipeline of the heating system of the building. - The discharge of air that remained trapped in the
tube 4 or in thetube 16 takes place opening thevent valve 15, so the air escapes. - In this regard it is preferable for the coil portion to be connected to the delivery of the
manifold 3 because in this case any air which may be contained in thetube 4 is favoured in its upward motion. - For the same reason, the substantially rectilinear and
horizontal portions 12 of the tubes and of thegroove 16 can be oriented in slightly oblique manner, in order to promote the rising motion of the air. - In the embodiment with two manifolds, instead, the heat-carrying fluid (hot water) enters the
manifold 3 through a union fitting 21, through acylindrical element 20 it passes into thetube 4, it flows through thewhole tube 4 heating theradiating plate 2, and it enters theupper manifold 18 through acylindrical element 20 thereof. - Then, through a union fitting 21 of the
manifold 18, the water is returned to the pipeline of the heating system of the building. - In this case, too, the discharge of air that remained trapped in the
tube 4 takes place opening thevent valve 15 in such a way that the air escapes and, naturally, the substantially rectilinear andhorizontal portions 12 of the tubes and of thegroove 16 can be oriented in slightly oblique manner, in order to promote the rising motion of the air. - Naturally the
union fittings 21 and thecylindrical elements 20 that are not used to connect tubes or vent valves are closed by means of plugs. - Moreover, it is clear that although only one coil tube (and one corresponding groove) has been described, in different embodiments there may also be more than one.
- In practice, it has been noted that the radiator with radiating plate according to the invention is particularly advantageous because it can be manufactured in a simpler, more economic manner than traditional radiators and, at the same time, it enables to enhance the heat exchange performance of the radiator.
- Advantageously, the horizontal coil shape enables to maintain the water in turbulent motion within the coil, to promote heat exchanges with the plate.
- The radiator with radiating plate thus conceived can be subject to numerous modifications and variants, without thereby departing from the scope of the inventive concept; moreover, all details are replaceable by technically equivalent elements.
- In practice, the materials used, as well as the dimensions, may be any depending on requirements and on the state of the art.
