Definitions

  • the present invention relates to a modular element for radiators intended for heating plants, to a radiator for heating plants and to a process for manufacturing of same.
  • the invention relates to a new modular element to be used for construction of radiators for heating plants, as well as to a radiator obtained through use of one or more of said modular elements.
  • the invention also relates to a process for manufacturing both the above mentioned modular element and a radiator obtained by use of said modular element.
  • radiators for heating plants presently on the market consist of a plurality of modular elements made of cast iron, steel or aluminium alloys for example, that are joined together by connecting elements such as nipples. It is to note that the number of elements and the sizes and shape of each element that will form a radiator can be varied depending on the available installation conditions in terms of available space, thermal power required, and aesthetic effect to be ensured.
  • the elements that are going to form a radiator typically have an upper collector and a lower collector connected by a series of suitably spaced-out columns inside which the heating fluid flows. These columns are of a variable number depending on the element type and typically can be of a number included between 1 and 10 columns.
  • the outer surface of the radiators is then designed for being the widest possible one, consistently with construction problems, in order to achieve the maximum exchange of heat energy with the surrounding environment, bulkiness and other thermal conditions thereof being the same.
  • the different elements constituting the radiator are joined together consecutively, then the radiator thus obtained is connected to a heating plant comprising a heat generator and pipelines bringing hot fluid, consisting of hot water or low-pressure steam for example, to the radiator.
  • the hot fluid passes through the pipelines within the radiator getting progressively cool and then comes out of an evacuation opening provided in the radiator itself.
  • radiators of the above described type have a questionable aesthetic aspect that often does not meet the architectonic or furnishing requirements that are wished for some types of environments. It is exactly due to their own conformation that radiators of the above described type, once installed, look like rigid non-deformable bodies which moreover are unable to define rest or support surfaces of easy use that surely would be advantageous in particular rooms such as bathrooms or bedrooms.
  • radiators of a second typology have recently appeared on the market. They are made up of tube bundles in sight, disposed parallelly of each other or coil-wise, for example. These radiators are usually obtained by end welding of several consecutive tubular elements so as to define the desired shape (in the form of a ladder or a coil, for example, as mentioned above). Still from a construction point of view and as an alternative solution to welding or gluing, in particular in cases in which pipes of reduced section or easy deformability are concerned, manufacture of coil radiators by consecutive bending of a single tubular element has been carried out.
  • radiators having pipes in sight highlight some negative aspects as well.
  • radiators of the above described radiators are complete absence of modular structures. Practically, coil radiators or radiators having a ladder-shaped structure are given particular sizes by the manufacturer, so that they may provide predetermined thermal powers. Therefore, in order to meet the most varied operating requirements, these radiators are made in a plurality of different shapes and sizes. Due to the fact that radiators of the second mentioned typology are rigid and preassembled structures since production, it is apparent that this negatively affects transportation of same and makes assembling not very practical.
  • the last-mentioned radiators are at all events scarcely able to define support regions for towels, linen, garments, etc. in that pipes defining them are disposed in mutual side by side relationship in a common lying plane.
  • Another object of the invention is to provide a modular element capable of being manufactured with large working tolerances while enabling an efficient assembling with contiguous modular elements so as to define a radiator.
  • the last-mentioned object is achieved by a process for manufacturing of tubular elements and radiators for heating plants in accordance with that which is described in the process claims 18 to 21.
  • radiators 1 for heating plants in accordance with the present invention are shown.
  • radiator 1 shown in Figs. 3 and 4 comprises a plurality of modular elements 2 consecutively connected and brought into fluid communication with each other. It is to note that each modular element 2 forming the radiator has an elongated tubular body 3, at one end 3a of which removable engagement means 4 is provided for carrying out a fluid connection between such one modular element and the consecutive modular element.
  • an inlet modular element and an outlet modular element are defined, which are connected at one end thereof with the delivery line 5 and the evacuation line 6 of the heating plant, respectively.
  • a radiator which comprises a plurality of modular elements 2 of the same type as illustrated in Figs. 3 and 4, which elements are however disposed in substantial parallel relationship with each other and each have one end put into fluid communication, by the removable engagement means 4, with a chamber 7 of a lower collector body 8 and one end opposite to the preceding one which, through the removable engagement means, is put into fluid communication as well with a chamber of an upper collector body (the upper portion of the radiator referred to in Figs. 5 and 6 is not shown, in that it is substantially similar to the lower portion thereof).
  • collector bodies will be conventionally connected with a delivery line and an evacuation line of the heating plant respectively, so as to enable hot-fluid circulation through the tubular bodies 3 of the radiator.
  • tubular bodies can also have a U-shaped or S-shaped conformation and be consecutively engaged with each other so as to define spatially-deformable articulated structures.
  • each modular element 2 has at least one end 3a (Figs. 2, 3 and 4) at which said removable engagement means 4 is provided or, as in the case in Figs. 1, 5 and 6, both ends are provided with this removable engagement means 4 for connection to respective collectors.
  • the above mentioned removable engagement means comprises at least one half 9 which, under operating conditions for assembling of the modular element so as to define a radiator (see both the example in Figs. 3 and 4 and the example in Figs. 5 and 6), is integral with the end of the elongated body.
  • the engagement means 4 also comprises a second half 10 which, under operating conditions for assembling of the modular element, is axially integral with the first half and with the latter defines a relative rotation axis 11 between the first and second halves 9, 10, which is directed transversely and in particular perpendicularly of the longitudinal extension axis of the tubular body.
  • Both the first and second halves 9, 10 are of tubular conformation to enable the fluid from the tubular body to pass therethrough.
  • Half 9 of the engagement means 4 comprises, as shown in particular in Figs. 1 and 2, a connecting body 12 removably engaged with the end 3a of the elongated body after interposition of an auxiliary connection element 13, of tubular conformation as well, welded to an attachment seating 14 provided at the end 3a of the elongated body.
  • the auxiliary connection element 13 is fastened to the attachment seating 14 by welding and is provided with a radially inner lip 15, disposed away from said end 3a of the tubular body, which lip under operating conditions defines a flat locating surface for a sealing element 16, as better clarified in the following.
  • the portion of the auxiliary connection element 13 which is external to the attachment seating has a cylindrical shape and is provided with an outer screw thread for receiving the connecting body 12, as already said, by removable fitting.
  • said body has a substantially U-shaped conformation and a substantially cylindrical inner surface provided with a screw thread adapted to mate the thread of the auxiliary connection element 13.
  • the connecting body 12, away from the end 3a of the tubular body has an axial-abutment lip 17 delimiting an opening to enable passage of fluid and defining a housing seat 18; a first portion of an interconnecting element 19 of tubular form as well, is fitted in said housing seat 18.
  • Said interconnecting element 19 has an axial-abutment ridge 20 cooperating with said lip 17 so as to ensure integrity in an axial direction of the interconnecting element 19 with the connecting body 12 and therefore with the end 3a of the tubular body when these elements are assembled together.
  • the axial-abutment ridge 20 associated with the first portion of the interconnecting element 19 that, as said, is accommodated within the housing seat 18 has a lower radial bulkiness than the housing seat itself, in order to enable a predetermined radial play between the interconnecting element 19 and the connecting body 12.
  • a connecting collar 21 between the first and second portions of the interconnecting element 19 (which collar crosses the opening delimited by lip 17) has a lower radial bulkiness than the opening defined by lip 17.
  • the attachment seating 14 provided at the end 3a of the tubular body, the auxiliary connection element 13 engaged by welding with the attachment seating 14, the connecting body 12 screwed down on the auxiliary connection element 13, the interconnecting element 19 partly fitted in the housing seat 18 and the housing seat itself are disposed coaxially with each other along a symmetry axis which is coincident with said axis 11.
  • the interconnecting body 19 at its second portion, has a screw thread, in this case a male thread, capable of engaging with a corresponding end provided with a female screw thread formed in a following modular element (Fig. 2) or with a female screw thread formed in the collector body 8 to which several modular elements of the above described type are connected.
  • a screw thread in this case a male thread, capable of engaging with a corresponding end provided with a female screw thread formed in a following modular element (Fig. 2) or with a female screw thread formed in the collector body 8 to which several modular elements of the above described type are connected.
  • an auxiliary annular ridge is therein defined which is arranged to receive a sealing ring 22 in abutment, which ring ensures the necessary fluid-tightness for connection between the second portion of the interconnecting element 19 and a following modular element, for example.
  • the modular elements can be manufactured in such a manner that they have one attachment seating 14 at both ends.
  • both attachment seatings 14 will be obtained by permanent set, will have a substantially cylindrical conformation and will be each arranged for accommodating corresponding removable engagement means 4 for connection with respective collectors, as shown in Figs. 5 and 6.
  • attachment seatings 14 possibly formed in the opposite ends of the elongated body, will be able to extend along opposite sides of the elongated body itself, as shown in chain line in Fig. 1.
  • tubular elements having U-shaped (or S-shaped) tubular bodies i.e. with a U-shaped (or S-shaped) longitudinal symmetry axis
  • the engagement means could be directly connected to the end or ends of the tubular body which would not require further deformations since the attachment seating is defined as a result of the U-shaped (or S-shaped) conformation of the whole tubular body.
  • the rectilinear tubular body is manufactured by extrusion for example, or a curvilinear tubular body (having an S-shaped, U-shaped or different conformation, for example) is manufactured by extrusion and subsequent bending.
  • the tubular body can be made of steel, aluminium, brass or another material adapted for the purpose.
  • a pipe bending machine or a machine tool for machining end portions of pipes is used. By this machine at least one end of the tubular body is machined that, being permanently set, defines the cylindrical attachment seating 14 intended for receiving the above mentioned removable engagement means 4.
  • the axis 11 of which will be disposed transversely of the longitudinal extension axis of the elongated body and in particular perpendicular to the axis of said body (in the case of rectilinear pipes), coupling of the attachment seating 14 with the above described removable engagement means 4 is carried out.
  • means 4 is directly brought into engagement with the attachment seating 14, without further deformation or permanent set operations being required.
  • connection element 13 first manufacturing of the connection element 13, the connecting body 12 and the interconnecting element 19 is carried out, if these pieces have not been previously made. Then coupling of the latter with the attachment seating 14 is carried out. In more detail, the following operations are executed: fastening, by welding for example, of the connection element 13 to said attachment seating 14, screwing down of the connecting body 12, with the interconnecting element 19 coupled therewith, on said auxiliary connection element 13, so as to define the housing seat 18. During this operation, the necessary annular seal 16 will be inserted between the interconnecting element 19 and the auxiliary connection element 13.
  • a further seal 22 is also provided at the second portion of the interconnecting element 19. This step can be obviously carried out either before or after the engagement means is associated with the attachment seating.
  • the invention achieves important advantages.
  • radiators of any configuration can be achieved which will meet both thermal and aesthetic requirements of any nature.
  • the marked modular character of the structure characterizing the modular element in reference enables radiators even of big sizes to be manufactured without difficulties arising on production.
  • the modular element in question can be manufactured by mere bending operations and subsequent assembling of components.
  • the engagement means to be associated with one or both ends of the modular element the latter also has a good capability of counterbalancing possible machining errors by means of the radially admissible plays between the first and second portions.
  • the structure of the modular element ensures a comfortable handling and packages in minimum spaces, which thing surely is not negligible.
