Definitions

  • the present invention relates to a radiator with radiating plate having high efficiency.
  • 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.
  • a thick plate of thermally conducting material e.g. aluminium
  • 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.
  • tubes typically made of copper
  • 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 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.
  • 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.
  • 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 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.
  • 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.
  • FIGS. 1 and 2 show a view of a radiator according to the invention with rectangular radiating plate respectively with one and with two manifolds;
  • FIGS. 3 and 4 show a view of a radiator according to the invention with oval radiating plate respectively with one and with two manifolds;
  • FIG. 5 shows a manifold according to the invention
  • FIG. 6 shows a sectioned detail of a plate at the tube and the groove.
  • the radiator 1 ( FIG. 1 or 3 ) comprises a plate 2 (typically made of aluminium) which bears, at its rear side (when the radiator is installed) a manifold 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.
  • a plate 2 typically made of aluminium
  • a manifold 3 typically made of aluminium or copper or stainless steel or carbon steel
  • a tube 4 made of copper, aluminium or stainless steel or carbon steel
  • the plate 2 has a groove 6 (obtained in the plate 2 e.g. by milling) into which is inserted the tube 4 .
  • the tube 4 presents ( FIG. 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 the tube 4 and the plate 2 .
  • 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.
  • the retaining of the tube 4 in the groove 6 and the heat exchange between the heat-carrying fluid contained in the tube 4 and the plate 2 in which are obtained the grooves 6 are further improved; moreover, the surface 4 a that faces the exterior of the tube 4 has its profile aligned with the profile 2 a of the plate 2 .
  • the tube 4 and the groove 6 have at least one coil portion 11 defined by a plurality of first segments 12 substantially parallel to each other and able to assume substantially horizontal position when the radiator 1 is installed, and second segments 13 interposed between said first segments 12 .
  • the coil portion 11 allows densely to cover the plate 2 .
  • the coil portion 11 of the tube 4 and of the groove 6 is at the delivery of heat-carrying fluid of the manifold 3 and the first segments 12 of the tube 4 and of the groove 6 are rectilinear.
  • FIGS. 3 and 4 show an embodiment of the radiator according to the invention in which the first segments 12 of the coil portion 11 of the tube 4 and of the groove 6 have mutually different length.
  • the radiator may have one or two manifolds.
  • the manifold 3 is positioned at the lower portion of the radiator 1 when the radiator 1 is installed and the coil portion 11 of the tube 4 and of the groove 6 develops upwards.
  • an air venting valve 15 (typically made of aluminium or copper or stainless steel or carbon steel).
  • the radiator presents a tube 16 and a corresponding return groove, which are interposed between the vent valve 15 and the manifold 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.
  • FIGS. 2 and 4 show two examples of radiators with two manifolds (an upper one and a lower one).
  • the tube 4 and the groove 6 defining the coil portion 11 extend from the lower area of the plate 2 and the tube 4 is fastened both to the lower manifold 3 and to an upper manifold 18 , which also bears the vent valve 15 .
  • 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 the plate 2 without using hooks, punches or other devices; hereafter reference shall be made only to the manifold 3 but the manifold 18 (when present) has the same structure.
  • the manifold 3 has two through holes delimited by cylindrical elements 20 projecting longitudinally, to which is fastened the tube 4 (or, when necessary, the vent valve 15 ).
  • 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).
  • manifold 3 is provided with threaded union 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 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 a cylindrical element 20 , it passes into the tube 4 .
  • the coil portion prefferably be connected to the delivery of the manifold 3 because in this case any air which may be contained in the tube 4 is favoured in its upward motion.
  • substantially rectilinear and horizontal portions 12 of the tubes and of the groove 16 can be oriented in slightly oblique manner, in order to promote the rising motion of the air.
  • the heat-carrying fluid enters the manifold 3 through a union fitting 21 , through a cylindrical element 20 it passes into the tube 4 , it flows through the whole tube 4 heating the radiating plate 2 , and it enters the upper manifold 18 through a cylindrical element 20 thereof.
  • 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.
  • 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.
  • the materials used, as well as the dimensions, may be any depending on requirements and on the state of the art.
