Definitions

  • the present invention relates to a tube radiator for heating and a method for producing a tube radiator for heating, in particular of the so-called "ladder" type.
  • a tube radiator for heating in particular of the commonly described “ladder” type, is generally composed of a plurality of tubes parallel to each other and arranged between two rails (normally, but not necessarily, vertical in use). Hot water (or, more rarely, some other hot fluid) circulates in the tubes and rails.
  • Tube radiators for heating of this type can be made of different materials and with different methods of manufacture.
  • aluminium radiators are usually manufactured by making the tubes and the rails separately and then assembling the tubes and rails.
  • the fastening of the tubes to the rails must be such as to ensure both an effective mechanical coupling and an effective watertight seal.
  • Document DE 198 23 635 A1 describes a tube radiator for heating, according to the preamble of claim 1.
  • Document EP 1 179 723 A2 describes a tube radiator for heating, comprising a pair of rails and a plurality of tubes inserted in holes of said rails.
  • One object of the present invention is that of providing a tube radiator for heating and a method for producing a tube radiator for heating that are advantageous with respect to known solutions; in particular, one object of the invention is to provide a tube radiator for heating and a method for its manufacture that enable the tubes to be fastened to the rails in a simple, rapid and effective manner.
  • the present invention therefore relates to a tube radiator for heating and a method for producing a tube radiator for heating as essentially defined in the appended claims 1 and 7, respectively, as well as in the dependent claims for the preferred additional characteristics.
  • the invention enables fastening the tubes to the rails of tube radiators for heating in a particularly simple, rapid and effective manner with respect to known solutions, ensuring both the mechanical coupling and watertight sealing in a fully satisfactory manner.
  • the invention also enables:
  • the invention also enables significantly reducing the defect rate in the joint areas between tubes and rails.
  • the coupling between tubes and rails in accordance with the invention also enables high production flexibility, allowing radiators to be made that have differentiated hydraulic circuits, without requiring supplementary steps in the production process.
  • Figure 1 shows a tube radiator 1 for heating, in particular of the so-called “ladder” type.
  • the radiator 1 comprises a pair of rails 2 (normally, but not necessarily, vertical in use), substantially parallel to and facing each other; and a plurality of tubes 3, arranged between the rails 2 and substantially parallel to each other and perpendicular to the rails 2.
  • the tubes 3 are spaced out along the rails 2, possibly spaced apart from each other in various ways and/or organized in groups.
  • each rail 2 comprises an extruded aluminium profile body 4 that extends along an axis A.
  • the body 4 has a lateral wall 5 that delimits a longitudinal internal chamber 6, which extends along axis A; advantageously (but not necessarily), the lateral wall 5 has a solid longitudinal base portion 7, parallel to axis A and facing the other rail 2, and a portion 8, for example curved or poligonal, which extends from the base portion 7 around axis A.
  • the base portion 7 preferably has an outer surface 11, substantially flat and facing the other rail 2, and an inner surface 12 facing the chamber 6.
  • Each rail 2 is provided with a plurality of through holes 13, axially spaced out from each other along the rail 2 and extending along respective axes B perpendicular to axis A.
  • the holes 13 are made through the base portion 7 of the lateral wall 5 of the rail 2, between surfaces 11 and 12, and for the thickness of the base portion 7 of the lateral wall 5.
  • Each hole 13 defines or comprises a seat 14 for the insertion of a tube 3.
  • Each rail 2 thus comprises a series of seats 14, axially spaced apart from each other to accept respective tubes 3 and extending along respective axes B.
  • Each hole 13 has a front inlet opening 15, formed on the outer surface 11 of the rail 2 and provided with a bevel or lead-in 16 converging towards the inside of the hole 13.
  • Each hole 13 comprises an outer portion 17, adjacent to the opening 15 and defining a seat 14, and an inner portion 18, adjacent to the chamber 6; portions 17 and 18 are substantially cylindrical and parallel to axis B (having a constant cross-section and diameter along axis B) and have different diameters, the outer portion 17 having a larger diameter than the inner portion 18; between the two portions 17 and 18, there is a narrowing 19 defined by the variation in diameter between the two portions 17 and 18; the portions 17 and 18 are united by a shoulder 20 facing the opening 15; the shoulder 20 can be a continuous annular shoulder around axis B, or be interrupted, i.e. constituted by one or more sectors separated from each other; the shoulder 20 is substantially perpendicular to axis B and parallel to the outer surface 11 of the base portion 7 of the lateral wall 5.
  • the tubes 3 are constituted by respective tubular bodies, made of extruded aluminium for example, like the rails 2.
  • Each tube 3 extends along an axis B (in use, coincident with axis B of a seat 14) between two axially opposite ends 21, provided with respective annular free end front edges 22.
  • Each tube 3 comprises a main central portion 23, for example substantially cylindrical in shape (i.e. having a constant cross-section and diameter along axis B), and two coupling portions 24, located at respective ends 21 and insertable in respective holes 13, or more precisely in respective seats 14, to join the tube 3 to the rails 2.
  • each coupling portion 24 is at least partially tapered towards the end 21 of the tube 3.
  • the coupling portion 24 comprises, starting from the edge 22, a tapered zone 25, converging towards the edge 22, and an interference zone 26, substantially cylindrical in shape.
  • the tapered zone 25 has a substantially truncated-cone shape and an outer diameter initially (i.e. at the free end front edge 22) less than the diameter of the seat 14 (i.e. of the outer portion 17 of the hole 13) to allow the insertion and centring of the tube 3 in the seat 14, but greater than the diameter of the inner portion 18 of the hole 13, so as to stop the edge 22 against the shoulder 20 if necessary (in any case, as will be explained below, the edge 22 is not necessarily in contact with the shoulder 20).
  • the interference zone 26 has a diameter such that it can be inserted with radial interference in the seat 14 (i.e. in the outer portion 17 of the hole 13), so as to join the tube 3 to the rail 2 by mechanical interference.
  • the interference zone 26 is substantially cylindrical.
  • the interference zone 26 is an annular zone extending axially along axis B and, in use, touches a corresponding portion of the inner annular surface of the seat 14 having the same shape, this also cylindrical; the coupling portion 24 and the seat 14 are in contact with each other on respective annular surfaces extending along axis B and both cylindrical around axis B; in other words, the mechanical interference between the coupling portion 24 and the seat 14 is not limited to an annular contact profile (a line), but takes place between two surfaces having a certain axial extension (along axis B).
  • the tapered zone 25 and the interference zone 26 are connected by a connection zone 27, tapered towards zone 25, but having less conicity than zone 25.
  • Each end 21 of a tube 3 is fastened to a rail 2 by a mechanical interference coupling 30, formed by the coupling portion 24, precisely by the interference zone 26, and by the seat 14, i.e. by the outer portion 17 of the hole 13 in which the coupling portion 24 is inserted with radial interference.
  • the mechanical interference between the coupling portion 24 and the seat 14 takes place mainly in the interference zone 26, but it can start in the tapered zone 25 as well, and also involve the connection zone 27 if necessary.
  • each coupling portion 24 is inserted in a seat 14 with the respective edge 22 facing or resting against the shoulder 20; not all of the coupling portions 24 necessarily touch a shoulder 20; the tubes 3 may actually have slightly different lengths, within the manufacturing tolerance limits; the longer tubes will abut against the shoulders 20, while the shorter tubes will stop short of the shoulders 20, as they are blocked by the radial interference between the respective coupling portions 24 and the respective seats 14; in this way, the invention also allows compensating for the manufacturing tolerances of the tubes 3.
  • Each end 21 is also permanently fastened in the respective seat 14 by gluing, welding, thermoelectric fusion or some other fastening technology.
  • each end 21 is also glued in the respective seat 14 by a layer 31 of adhesive applied between an outer lateral surface 32 of the coupling portion 24 and an inner lateral surface 33 of the seat 14 (i.e. of the outer portion 17 of the hole 13); the adhesive layer 31 is mainly laid on the tapered zone 25 (occupying the radial space between the inner lateral surface 33 of the seat 14), and to a lesser or residual extent on the interference zone 26 (and possibly on the connection zone 27); the adhesive layer 31 is laid around the coupling portion 24 to form a continuous annular sealing element 34, which ensures both the watertight seal and the mechanical seal between the coupling portion 24 and the seat 14.
  • the adhesive in the layer 31 is suitable for gluing together the materials with which the rails 2 and tubes 3 are made, in particular for gluing aluminium.
  • the adhesive can be a heat-reticulated epoxy adhesive; examples of usable adhesives are those of the Hysol® family manufactured by Henkel, or adhesives having similar characteristics.
  • the adhesive layers 31 In addition to firmly joining the tubes 3 to the rails 2, the adhesive layers 31 also act as watertight sealing elements, constituting respective sealing elements 34.
  • the radiator 1 has differentiated holes 13 along the rails 2.
  • At least some holes 13 of each rail 2 have differentiated narrowings 19 (with different cross-sections) depending on the position of the holes 13 along the rail 2.
  • a hole 13 is shown in Figure 7 having a larger narrowing 19 than the holes 13 shown in Figures 3, 4 and 6 .
  • the holes 13 have outer portions 17 (defining the seats 14) substantially all the same, while they have inner portions 18 of different diameter depending on the position along the rail 2.
  • the rails 2 preferably have respective groups of holes 13 with different inner portions 18 and, therefore, different narrowings 19.
  • the tubes 3 are fitted with internal fins 35, located inside the tubes 3 and extending from respective internal lateral surfaces of the tubes 3; for example, as shown by broken lines in Figures 5 and 6 , each tube 3 is provided with a plurality of longitudinal fins 35 parallel to each other and to the axis B of the tube 3 and arranged radially around axis B; in any case, it remains understood that the tubes 3 could be provided with fins 35 of another shape and arrangement.
  • the fins 35 enable "catching" heat from the hottest areas of the fluid circulating inside the tubes 3 and transferring said heat to the outer surfaces of the tubes 3.
  • the above-described radiator 1 is made using the method described in claim 7.
  • the couplings 30 can be sealed by gluing, welding, thermoelectric fusion or some other technology; for example, the step of sealing the couplings 30 includes a step of gluing each coupling portion 24 in the associated seat 14, in particular by gluing together the outer lateral surface 32 of the coupling portion 24 and the inner lateral surface 33 of the seat 14.
  • the radiator 1 is made, through implementation of the method of the invention, in the following manner.
  • both the rails 2 and the tubes 3 are made of aluminium (or an aluminium alloy) by an extrusion process; the rails 2 and the tubes 3 are thus constituted by respective monolithic extruded tubular elements.
  • the holes 13, or more precisely the outer portions 17 and inner portions 18, having different diameters, of the holes 13, are then made in the rails 2 by machine drilling, thereby also forming the seats 14, the narrowings 19 and the shoulders 20.
  • the ends 21 of the tubes 3 are provided with opportunely shaped coupling portions 24, in particular to form the tapered zone 25, the interference zone 26 and, optionally, the connection zone 27.
  • This operation apart from providing the tubes 3 with the coupling portions 24 for coupling to the rails 2, allows achieving the desired design dimensions in a precise and reliable manner, also achieving a reduction in the tolerance range of the part with respect to that of the extrusion process.
  • Adhesive is then applied to provide the adhesive layers 31; for example, the adhesive is applied on the seats 14, in particular on the inner lateral surfaces 33 of the seats 14 (i.e. on the outer portions 17 of the holes 13).
  • the tubes 3 are then joined to the rails in an assembly step that comprises the steps of:
  • the rails 2 are placed on respective guides 40A and 40B that are movable with respect to one another and parallel to each other; for example, the rails 2 are placed on a moveable guide 40A, connected to a piston 42 of a pressing apparatus 43, and on a fixed guide 40B.
  • the tubes 3 are placed on a rack 44 provided with mounting seats 45 that hold the tubes 3 in the desired configuration, i.e. spaced out from each other.
  • the rack 44 is placed between the guides 40A and 40B, with the tubes 3 aligned with respective pairs of seats 14 on the facing rails 2.
  • All of the tubes 3 are assembled on the rails 2 in a single step, by means of the pressing apparatus 43, which pushes the guides 40A and 40B towards each other (by operating, for example, the piston 42 connected to the movable guide 40A) and exerting the pressure necessary for fitting the tubes 3 on the rails 2, forming an assembly 50.
  • the assembly 50 formed by the rails 2 and the tubes 3 is then subjected to a step of sealing the couplings 30, to join the tubes 3 to the rails 2 in a fluid-tight manner.
  • the assembly 50 is subjected to a heat-treatment step, in particular a baking step, to obtain the polymerization/reticulation of the adhesive and thus complete the watertight sealing and mechanical sealing of each coupling 30.
  • a heat-treatment step in particular a baking step
  • the sealing step could comprise a different process, for example, a welding process, in particular laser welding, or thermoelectric fusion, without material removal; the welding or thermoelectric fusion process is carried out, without material removal, along a peripheral edge 36 of the opening 15 to produce a bead 37 of material of the tube 3 and/or the rail 2 around the peripheral edge 36 ( Figure 6 ); the bead 37 firmly joins the tube 3 to the rail 2 in a fluid-tight manner.
  • a welding process in particular laser welding, or thermoelectric fusion
  • the step of making the holes 13 in the rails 2 by machine drilling comprises a step of making differentiated holes 13 along the rails 2, i.e. holes 13 having different narrowings 19 along the rails 2.
