Description

The present invention relates to element radiators

  heaters horizontally juxtaposed and traversed by a heating fluid.

  The field concerned is more particularly that of radiators whose heating elements are of moldable material, in particular cast iron, without this however constituting a limitation for the invention. Such radiators have been known for many years,

  and their basic design has changed little.

  The builders have certainly proposed some improvements

  For example, French Patent No. 2,435,013, or European Patent No. 0 079 896, but without modifying the basic structure of these radiators. Traditional heaters with juxtaposed heating elements have a satisfactory flexibility to modulate the power of these heaters, by varying the number of heating elements However,

  the horizontal elongation of a radiator induces

  that are not always compatible with the available wall length. However, there is a growing need to be able to organize the installation of radiators to take into account the particular conditions of installation, including the available space for such a facility, while ensuring a rational nature to their manufacture. The object of the invention is to provide a radiator providing a

  such flexibility, and the establishment of which is easy and rational.

  The invention also aims to provide a radiator whose design allows easy realization of moldable material, for example cast iron, with a more satisfactory aesthetic than

  that of traditional cast iron radiators.

  It is more precisely a radiator with heating elements juxtaposed horizontally and traversed by a heating fluid, characterized in that it is constituted by a plurality of horizontal unit modules arranged one above the other to form a stack vertical, each of said modules having the same number of juxtaposed heating elements, and two lateral collectors extending vertically over the entire height of the stack on either side thereof, including a first supply manifold which is connected to each of the unit modules by a first fixing and communication means, and a second return collector which is connected to each of said modules by a second fixing and communication means offset in height with respect to said first associated means of fixing and

Communication.

  Preferably, the first and second fixing and communication means are identical and interchangeable; in particular, each fastening and communication means is essentially constituted by a threaded collar bushing passing through an associated bore of the collector concerned, said sleeve being screwed onto the element

  adjacent heater of the unitary unit concerned.

  According to another advantageous characteristic of the invention, one of the two collectors is also connected to each of the modules

  horizontal units by means of a third means of fixing and communicating

  cation capable of providing a purge function, said third fixing and communication means being, for each unitary module, disposed substantially at a level at least equal to that of the highest of the first and

  second fastening means and communication associated.

  Advantageously, in addition, the third attachment and communication means are essentially identical to the first and second fixing and communication means, differing from each other.

  these only by their passage section.

  Preferably, each of the flanged sleeves forming part of the first, second, or third fixing and communication means is screwed into a threaded ring internally and externally, said ring being screwed into an associated thread of

the heating element is concerned.

  It may be advantageous for each unitary module to have a fourth fastening means for centering the collector corresponding to the highest of the first and second associated fixing and communication means, said fourth fastening means consisting essentially of a welded pawn. manifold, and received in an externally threaded ring, said ring being screwed into a

  associated tapping of the heating element concerned.

  According to a preferred embodiment, each unitary module has laterally four threads arranged along the corners of a rectangle, including two upper threads associated with the third attachment and communication means and the higher of the first and second fixing and communication means. , and two lower threads associated with the fourth fastening means and at least one of the first and

  second fixing and communication means.

  Preferably, each of the collectors has access holes facing the first, second, and third fixing and communication means, so as to facilitate the assembly or disassembly of the collared bushings associated, said access holes being normally

  plugged by a plug when said radiator is mounted.

  Each manifold has orifices for connecting said manifold to the heating fluid network, and for purging and emptying the assembly. It may be particularly advantageous to provide for these orifices to be arranged at the end of the manifolds. allows to arrange the power and return sockets, indifferently in the lower part or in the upper part thereof, the unused orifices being closed by a removable plug, which can be a solid plug, a plug

  trap, or drain plug.

  It is also interesting that the radiator comprises hooking means and / or support for its disposition against a wall; in particular, it can be provided that the attachment means only provide an anti-tilt function, the weight of the radiator being supported by the support means organized as removable feet and adjustable in height, arranged under the heating elements of the

  unit unit lowest of said radiator.

  Preferably then, the heating elements have, in the upper part of their rear column, two short ribs projecting laterally, allowing attachment of the radiator by one of its unit modules on a bracket fixed to the wall; it is also interesting that the heating elements have, in the lower part of their rear column, two continuous ribs projecting laterally, allowing the guiding and the passage of a double leg provided in the upper part of

  each removable foot for additional anti-tilt function.

  Advantageously, at least one of the heating elements of each unit module having a front plane facet; in particular, the flat front facet of each heating element has a decor

  outside, for example grooving or embossing.

  By way of particular example, the heating elements of each unitary module are preferably made of moldable material,

especially cast iron.

of the heating element.

  FIG. 1 makes it possible to distinguish a radiator 1 with heating elements juxtaposed horizontally 2 and traversed by a heating fluid. According to an essential aspect of the invention, the radiator 1 essentially consists of a plurality of horizontal unit modules 10 arranged one above the other to constitute a vertical stack, each of said modules comprising the same number of heating elements juxtaposed 2 This radiator thus comprises N horizontal unit modules 10, each of said modules having N heating elements juxtaposed 2: in the particular case of Figure 1, we have N = 3 and N = 6, but it is only natural that An example may also be provided a single heating element disposed between the side collectors The radiator 1 further comprises two lateral collectors 3 and 4 extending vertically over the entire height of the stack, on either side thereof There is thus provided a supply manifold 3, which is connected to each of the unit modules 10 by a first means of attachment and communication 100, and another c return collector 4, which is connected to each of said modules by a second fixing and communication means 200 offset in height with respect to said first associated fixing and communication means In the particular case of FIG. 1, the collector 3, or left collector, is the supply manifold, and the heating fluid supply is from the bottom of this collector, as shown schematically by the arrow A; the collector 4, or right collector, is then the return collector, corresponding to the output of the heating fluid, this outlet being here provided in the lower part of said collector, as shown schematically by the arrow R In this arrangement, the first fixing means and 100, corresponding to the input of the heating fluid for each unit module 10, is disposed in the upper part of said module, while the second fixing and communication means 200, corresponding to the output of the heating fluid for each unit module 10 , is arranged in the lower part of said module FIG. 2 makes it possible to better visualize the circulation of the heating fluid, the diagonal arrow trajectory schematizing this circulation going from

  means 100 to 200, for each horizontal unit module 10.

  According to another important characteristic of the invention, one of the two collectors is connected to each of the horizontal unit modules 10 by a third fixing and communication means 300 which can provide a purge function, these third fixing means and communication, for each unitary module, are arranged substantially at a level at least equal to that of the

  of the first 100 and second 200 means of fixing and

  associated communication: in the particular case of Figures 1 and 2, each of the third attachment and communication means 300 is associated with the right collector 4, and is disposed substantially at the first means

  fixing and communication 100.

  As is schematized in FIGS. 1 and 2, each unitary module 10 also has a fourth attachment means 400 for centering the collector corresponding to the highest of the first 100 and second 200 associated fixing and communication means: In this case, the fourth fixing means 400 serve for centering the

left collector 3.

  The particular structure of each of the fixing and communication means 100, 200, 300, and each of the fixing means 400,

  will be described in more detail below with reference to Figures 7 to 9, and 27.

  It should be observed that the means 100, 200, 300, 400 are here arranged according to the vertices of a rectangle, and this for each of the horizontal unit modules 10 This is of course only one example, but such an arrangement presents many advantages in simplifying the manufacturing of heating elements

  constituting the horizontal unit modules of the radiator.

  The structure of the radiator according to the invention provides a great

  flexibility to adapt to multiple installation conditions.

  FIGS. 1 and 2 illustrate the case of a supply at the bottom of the left-hand collector and of a return at the bottom of the right-hand collector, for each horizontal unitary module 10, with a heating fluid inlet. the means 100 disposed in the upper part of this module, and a heating fluid outlet by the means 200 disposed at the bottom of said module. In this case, it is a generalization of a circulation from the bottom to the top for each horizontal unit module 10, according to

  to a provision that the Anglo-Saxons call "top and bottom".

  The schematic figures 3 to 3 h illustrate different arrangements of the supply and the return of the heating fluid, each figure being, for simplicity, limited to a single horizontal unit module, it being understood that the same applies to the other modules unit

  horizontals constituting the stacking concerned.

  3 a: the supply is via the bottom of the left manifold 3 and the return is via the bottom of the right manifold 4, and the circulation of the heating fluid is effected from the top to the bottom, from the medium 100 to the medium, in accordance with the principle previously described with regard to

Figures 1 and 2.

  3 b: the supply is still carried out by the left collector 3, but in the upper part thereof, the return being through the lower part of the right collector 4, and the circulation of the heating fluid is carried out as previously of the bottom up, from middle 100 to

average 200.

  Figure 3 c: the supply of heating fluid is at the bottom of the left manifold 3, while the return is in the upper part of the right manifold 4, and the circulation of the heating fluid is carried out there

  still from top to bottom, from means 100 to means 200.

  Figure 3 d: the feed is in the upper part of the left manifold 3, and the return in the upper part of the right manifold 4, the flow of the heating fluid is again effected from top to bottom, the means 100 to

average 200.

  Figure 3 e: the feed is at the bottom of the right manifold 4, and the return in the lower part of the left manifold 3, the circulation of the heating fluid is then effected from the bottom to the top, the means 200 by means of

100.

  Figure 3 f: the feed is at the bottom of the right manifold 4, and the return to the top of the left manifold 3, the circulation of the heating fluid being effected, as for Figure 3 e, from bottom to top,

  i.e., means 200 to means 100.

  3 g: the supply is carried out in the upper part of the right collector 4, and the return in the lower part of the left collector 3, the circulation of the heating fluid being done as before from the bottom up in

ranging from 200 to 100 means.

  Figure 3 h: the supply is in the upper part of the right collector 4, and the return in the upper part of the left collector 3, the circulation of the heating fluid is again effected from bottom to top, that is to say say by going

from means 200 to means 100.

  The schematic figures 3a to 3h thus clearly demonstrate the great flexibility provided by the structure of the radiator according to the invention, flexibility that makes it possible to adapt very easily to the various particular conditions of the installation of the radiator, without having In practice, however, if the installer has the choice, it will be preferable to adopt one of the arrangements illustrated in FIGS. 3 a to 3 d, that is to say with a supply by the left collector with an inlet at the top of each horizontal unit unit 10: in fact, the circulation of the heating fluid from top to bottom is then carried out in a "natural" direction, so that the transmission power The heat sink is slightly better than for a layout according to one of Figures 3 e to 3 h It should be noted that the side collectors also participate in heating, because they are traversed by the fluid cha which constitutes an additional advantage of the

  point of view of the power of emission of the radiator.

  It should also be noted that purges are not mandatory in some of the above provisions: for example, in the

  provision of Figure 3 d, the purge means 300 is actually useless.

  However, by systematically providing the disposition on each horizontal unit module 10 fixing and communication means, 200, 300, it is extremely easy to adapt to each situation

  particular for the installation of the radiator.

  Figures 4 to 6 can better distinguish the structure of a complete radiator, with its support means and anti-tip hooking. One thus distinguishes the radiator 1, with its horizontal unit modules 10, each of which here comprises a set of six elements

heated juxtaposed 2.

  It is found that the front face of the radiator has a satisfactory appearance, insofar as the front column of each heating element 2 here has a front plane facet 211 which can

  include an external decoration, for example grooving or embossing.

  These rectangular planar facets 2 are arranged in a grid, being separated by vertical intervals 212 between adjacent heating elements, in the same horizontal unitary module, and by preferably identical intervals 213 between the superimposed elements of two adjacent unitary modules. It goes without saying that these intervals 212 and 213 also contribute to the good ventilation of the heating elements of the radiator. Such a structure makes it possible, in particular, to produce the heating elements 2 of each unitary module 10 made of moldable material, in particular made of cast iron. It should therefore be observed that the modular cast iron radiator illustrated here has a much more aesthetic appearance than that of the conventional cast iron radiators, the front face of each heating element was traditionally made with a convex angular shape, with a central shelf It will naturally be possible to provide front faces of various shapes, in particular concave or convex, which can also be decorated, with the addition

  possibility of alternation between them.

  FIGS. 4 to 6 make it possible to distinguish fastening means 500 and support 600 with a view to arranging the radiator against a wall M It is possible to hang the radiator at the wall M by means of attachment, or to predict, as is the case here, that

  the attachment means 500 only provide an anti-tamper function.

  tilting, the weight of the radiator then being supported by the support means 600, which are preferably organized in the form of removable feet and adjustable in height, arranged under the heating elements of the

  unit unit lowest of said radiator.

  The hooking means 500 comprises a double bracket 501 whose lateral walls 505 have a hook shape allowing attachment to the upper part of the radiator. The structure of the double bracket 501 is better visible in FIGS. 13 to 15: thus the bottom 502 of the double square, having oblong orthogonal slots 503 and 504 for screw fixing on the wall M, the shape and arrangement of these lights allowing adjustment of the horizontality of the square, and side walls 505 each having a notch 506 allowing attachment of the radiator The attachment of the radiator can naturally be organized in different ways: it could be expected to report and solder tabs at the top and bottom of each side collector, for a hook on two brackets similar to the bracket 501 shown here It is however interesting to provide a direct hook on the elements c themselves, especially

  when said elements are made of cast iron.

  Figures 10 and 11 illustrate such a possibility, and can thus be distinguished, the presence of a particular ribbing directly obtained

  foundry, in order to hang the radiator.

  As can be seen in FIG. 10, each heating element 2 here has a front column 21 and a rear column 22 (this is of course only one example, since it is possible to provide heating elements with more than two columns, or the single column heating elements) The rear column 22 of each

  heating element 2 has a continuous rib 221 projecting laterally

  on either side of said rear column, and a parallel interrupted rib 222, the interruption of which defines a fastening rib 2 '22 in the upper part of said rear column. Such a ribbing is admittedly conventional in the field Cast iron radiators, but the presence here of ribs is not usual The realization in foundry naturally allows to realize a rib 2 '22 of a thickness slightly greater than that of the interrupted rib 222 It It is easy to understand, with reference to FIGS. 10 and 11, that it suffices to insert the two lateral parts 505 of the double bracket under two hooking ribs 2 '22, then to lower the radiator for a hooking. the latter, which attachment is in fact here only an anti-tilt The rib 221, which is a continuous rib, is also used, but in the lower part of the radiator, to provide an anti-tilt function thereof, in cooperation with a double leg provided in the upper part of each foot 601 removable and adjustable in height, as will be described in more detail below, with reference to

  Figures 18 to 26 relating to such a support foot.

  The attachment mode of the radiator on the double bracket 501 can naturally vary, and in particular adapt to a variable number of heating elements juxtaposed Thus, in Figure 12, there is a particular case of a radiator five juxtaposed heating elements 2, each heating element comprising a front column 21 and a rear column 22 The double hooking bracket 501 cooperates in this case with a hooking rib 2 '22 of the rear column 22 of the extreme elements of the module Figure 16 shows that with a greater number of juxtaposed heating elements 2, for example eight elements, it is possible to organize a hooking by means of the double bracket 501 by the hooking rib 2 '22 of the back column 22 of two elements

  heaters that are not end elements.

  FIG. 17 illustrates the case of a radiator with six juxtaposed heating elements, on which reference is made to the above-mentioned vertical intervals 212 separating the flat front faces 21 from the front columns 2. FIG. 17 also makes it possible to distinguish the support means 600. provided in the lower part of the radiator, means that will be

described below.

  It will thus be understood that there is a great deal of flexibility, both in a horizontal direction (by the choice of the number of heating elements juxtaposed), and in a vertical direction (by the choice of the number of horizontal unit modules stacked), which allows

  to adapt to the particular conditions required with great ease.

  Figures 4 to 6 distinguish the support means of the radiator 600, with in particular two legs 601, ending inferiorly by an adjustable end 609, each foot 601 having a portion 602 forming a cradle at the level of the connection line in the lower part of the lower unitary unit (such a line is also called "line nipples" by specialists) As is visible in Figure 4, the provision of such support on cast iron by the two feet 601 can clear the lower zone of the left and right collectors 3 and 4, so that there is a free space that easily allows the usual fluidic connection means to be arranged in the lower part of these collectors FIGS. 5 and 6 make it possible to distinguish, in part high of each foot 601, two offset fins 604 and 605 defining a double leg, and between which passes the continuous rib 221 above, whose upper part is visible in Figures 10 and 11

previously described.

  Referring now to FIGS. 18 to 26, it can be seen that the foot 601 includes a cradle portion 602, surmounted by an upper portion ending in a head 603 provided with the two aforementioned offset wings 604 and 605. The lower part 606 of the foot 601 has a tapping 607 for disposing a mouthpiece

  adjustable 609 whose structure is better visible in Figures 25 and 26.

  The adjustable end 609 has indeed a central sleeve 610, and a threaded rod 611 whose upper part is received in the tapping 607, and whose lower part enters an adjustable end-shaped shoe 612 It is thus easy, in rotating the bushing 610, adjust the height of the cradle 602 for a perfect positioning This makes it easy to organize the anti-tilt hooking described above, by actuating the two adjustable end pieces to lower the radiator arranged vertically on its two legs. A height sufficient for the hooking ribs to penetrate into the notches of the square FIGS. 18 to 20 also make it possible to distinguish two lateral notches 608, which can be used to arrange a holding pin when the

  radiator is in its final position on its two support legs 601.

  In practice, it is easy to set up each foot 601 by inserting the head 603 thereof, in a position such that the two offset fins 604 and 605 pass on either side of the continuous rib 221 of the two adjacent rear columns concerned It may also be advantageous to provide a short, narrower, lower extension of the continuous ribs 221, to provide a preliminary guide function by supporting the first fin 605 Thus, when the feet 601 are in position, the radiator rests on the cradle portions 602, and the offset fins 604 and 605 of each leg 601 provide an anti-tilt effect by cooperation with the continuous ribs 221 concerned. We will now describe the structure of the means 100, 200,

  300, 400, with reference to Figures 7 to 9.

  FIG. 8 makes it possible to distinguish the structure of each of the first fastening and communication means 100. A flanged bush 101 is thus found, passing through a bore 102 of the collector 3, the

  flange 103 of this sleeve being disposed within this manifold.

  The bushing 101 is screwed on the adjacent heating element 2 of the unitary module 10, preferably, as illustrated in FIG. 8, by screwing itself into a ring 105 fixed internally and externally, said ring being in turn screwed into an associated tapping. 106 of the heating element 2 concerned It may be possible to have an intermediate sealing element 107 between the collector 3 and the adjacent heating element 2. FIG. 8 also makes it possible to distinguish an access pierce 108 provided on the collector 3, in view of the first fixing and communication means 100, so as to facilitate the assembly or disassembly of the flanged sleeve 101, this access bore being normally closed by a plug 109 when the radiator is mounted can for example provide a cross section 104 of central hexagonal shape, so that the mounting or dismounting of the sleeve 101 can be easily performed by the per access 108, using a corresponding tool of the

Allen key type.

  According to an advantageous characteristic of the invention, the first fixing and communication means 100 and the second

  fixing and communication means 200 are identical and

  In this case, the second means of fixing and communicating

  cation 200 have exactly the same arrangement as that illustrated in FIG. 8, so that the same references increased by 100 in the same figure have been indicated, it being understood that the representation of the second fixing and communication means 200 are to consider in a reversed position (up / down) but with

exactly the same structure.

  Each of the third means of fixing and communicating

  300, as shown in Figure 7, is preferably substantially identical to the first 100 and second 200 fixing and communication means described above, differing from them only by the passage section of the collar bushing On has therefore taken the same references as in Figure 8, increased by 200 relative to the first fixing and communication means 100 It should simply be noted that the central passage 304 of the bushing 301 of each of these means 300 is here a smaller section than for the first and second fixing and communication means It is easy to note, with reference to FIGS. 7 and 8, that the common components used for joining the left and right collectors make it possible to use a number minimum of parts, with a very high ease of implementation, both

  for mounting only for disassembly of the radiator.

  FIG. 9 makes it possible to better distinguish the structure of the fourth fixing means 400, which serves to center the collector 3 corresponding to the highest of the first and second associated fixing and communication means. The fourth fixing means 400 is thus essentially constituted by a pin 411 welded to the manifold 3, and received in the associated bore 412 of a ring 405 externally threaded, said ring being in turn screwed into an associated thread 406 of the heating element 2 in question In practice, it will be possible to provide preferably a ring 405 whose external threading is identical to that of the rings 105, 205, 305 associated with the fixing and communication means 100, 200, 300. It is thus clear that each unitary module 10 may have laterally four threads 106, 206, 306. , 406 disposed at the vertices of a rectangle, including two upper threads 306, 106 associated with the third attachment and communication means 300 and the

  higher 100 of the first and second means of securing and communicating

  and two lower threads 406, 206 associated with the fourth fastening means 400 and at least 200 of the first and second fastening means

fixing and communication.

  Moreover, each of the collectors 3, 4 has, preferably at one or the other of its ends, an orifice making it possible to arrange the usual power supply and return plugs, indifferently in the lower part or in the upper part of the According to the arrangement described here, the feeding and the return is carried out in the lower part respectively of the left manifold 3 and the right manifold 4, so that the orifices concerned are similar to the orifice 410 illustrated in FIG. unused can simply be closed by a removable cap, such as the cap 110 or 310 of Figures 8 and 7, this removable cap can be indifferently a solid cap, a purge cap, or a stopcock drain valve as appropriate ( the stopcock will in practice be reserved for the case where the unused orifice is partly

bottom of a lateral collector).

  FIG. 27 illustrates an alternative embodiment of the flanged bush 101 previously described with reference to FIG. 8. In this variant, the flanged bush 101 'passes through a double bore 102 of the collector 3, and its flange 103' is then external. In this case, the sleeve 101 'has a transverse passage 113' communicating with the central passage 104 'providing communication with the interior of the adjacent heating element 2. In addition, the sleeve 101 'is screwed here directly into the associated thread 106 of the heating element 2, without an intermediate ring. It will also be noted the presence of a polygonal blind hole 114', for example of square section, facilitating assembly and disassembly of the sleeve 101 'As in the case of Figure 8, it is preferable to provide a seal 107 between the manifold 3 and the heating element 2, and an additional flat gasket 115 'between said collector and the flange 103' of the sleeve 101 'It goes without saying that this variant may relate to the first 100 and / or the second 200 fixing and communication means associated with each horizontal unit module 10, using collar sockets 101 'or 201' which are identical and interchangeable; likewise, the fixing and communication means 300 (purge function) may comprise a socket similar to the sleeve 101 ', but with a

narrower central passage.

  The foregoing description shows that the modular structure

  The radiator according to the invention makes it possible to organize the implantation of this radiator with a very great flexibility, so that one can easily take into account very variable conditions of installation, while conferring

  a rational character to the manufacture of such a radiator.

  The invention is not limited to the embodiment which has just been described, but on the contrary covers any variant with

  equivalent means, the essential features of the

tions.
