Definitions
- the present invention relates to production of thermal radiators.
- Thermal equipment industry in particular for domestic heating, uses radiators formed by tubular radiant elements arranged vertically and equipped at their ends with relative heads that define suitable reciprocal connection means; the heads are connected one to another by e.g. threaded couplings, provided with suitable sealing means.
- the above mentioned radiant groups are entirely obtained by die-casting or otherwise made of a pair of heads obtained by die-casting, to which a tubular element is connected; in some cases the tubular element is suitably finned so as to improve heat diffusion.
- the radiant groups obtained in this way are usually expensive.
- the object of the present invention is to provide a method which allows to obtain cheap radiant groups for thermal radiators.
- Another object of the present invention is to provide a method for producing safe to use and highly efficient radiant groups for thermal radiators in a simple way.
- the subject method includes first, die-casting of the bodies 20 of a pair of end heads 2 of a radiant group 1. These heads are preferably made of aluminium.
- Each body 20 has a flattened form, with outer corners suitably rounded, and has a cavity 21 extending on a median plane from its top narrow surface.
- An opening 25 extends along the top surface of the body 20, so that the cavity is open to the outside. The edges of the opening 25 are bevelled.
- the channels 22 have circular section and limited axial extension. Moreover, on their inner surface, the channels 22 feature respective shoulders 24.
- the cavity 21 communicates also with a pair of pipe stubs 23, extending from opposite sides of the body 20.
- the axis of each pipe stub is perpendicular to the median pane of the body.
- the inner surface of the pipe stubs 23 is threaded, so as to form threaded sections 26, so that respective couplings 4 can be screwed thereto for connecting two or more adjacent radiant groups 1.
- the cavity 21 of the body 20 is closed on the side opposite to the channels 22 by a shaped plate 28, whose form is complementary to the opening 25; the closing plate 28 is firmly joined to the body 20 by a peripheral welding 29 (Fig. 4).
- the closing plate 28 has preferably a rounded profile, so as to reconstruct the continuity of the outer surface of said head 2.
- the so made heads 2 are firmly joined by the channels 22 to the opposite ends of a corresponding plurality of tubular radiant elements 3, arranged coaxial to the same channels 22 (Fig. 5).
- the tubular elements 3 are preferably obtained by extrusion.
- the tubular radiant elements 3 are aimed at being tightly introduced inside the channels 22 and, at their ends, these elements 3 are provided with respective tapered mouths 30, which engage with the narrow part of these channels 22 defined by the relative shoulders 24.
- Respective gaskets 31 are mounted on the mouths 30 for keeping them tight against the above mentioned shoulders 24.
- the tubular radiant elements 3 are firmly joined to the heads 2 by suitable glues, spread on the coupling housings defined by the channels 22 of the heads 2.
- the so obtained radiant group 1 is put in a vice equipped with a centring device 10 which precisely determines the distance between the centres of said threaded pipe stubs 23 of the heads 2 (Fig. 6).
- the device 10 is substantially formed by a frame 11 equipped, on its ends, with a pair of pegs 12, protruding transversally and aimed at engaging said pipe stubs 23 of the heads 2 of the radiant group 1.
- the distance between the pegs 12 is adjustable.
- the device 10 supports respective vices 13 which clamp the above mentioned heads 2 of the radiant group 1.
- the radiant group 1 is mounted on the device 10 by introducing the pegs 12, whose distance is precisely determined, into the pipe stubs 23 of the heads 2 and then by tightening these heads 2 between the vices 13 (Fig. 7).
- the radiant group 1 is kept in the vice for a period of time sufficient for completing the step of gluing the tubular elements 3 to the heads 2.
- the couplings 4 feature, in known way, sections threaded in opposite directions, separated by the above mentioned seal 5.
- the couplings 4 are preferably obtained from a metallic sheet, as disclosed in the Patent Application No. BO95A 000175, filed by the same Applicant.
- the subject method allows to obtain, in a simple way, radiant groups for heat radiators, formed by a pair of end die-cast heads and a plurality of tubular radiant elements.
- the above mentioned radiant groups support three tubular elements between the heads.
- tubular elements arranged in line can be provided, the number of which depends on requirements.
- tubular elements can be arranged not only in one line, but also in two or more lines, by providing the end heads with a corresponding number of channels connecting with these tubular elements.
- the length of the tubular elements can vary in relation to use specifications.
- the last feature results in advantageous lightness of the radiant groups, which facilitates their transport and assembling.
