Abstract

The radiator for central heating comprises a number of hollow radiating elements (2) arranged so as to form a row, the ends of the radiating elements (2) being connected respectively to a first and to a second collector (3, 4) which are opposite and comprise orifices (16, 17) which communicate with corresponding orifices (14, 15) of the radiating elements. The radiating elements are fixed to the collectors by welding around the orifices. The collectors (3, 4) have a generally triangular outline and said communicating orifices (16, 17) of each collector (3, 4) are arranged in a part forming an edge of the latter.

Description

The invention relates to radiators of

central heating with hot water.

  We know radiators including a

  series of transmitting elements in the form of tubes

  placed vertically and forming a row or battery. The tubes are at their ends connected to each other

  others and include intermediate parts

  cuts to form elongated lights

  extending between the emitting elements in order to improve

  10. improve the air circulation through the radiator.

  The tubes have holes in their ends

  lateral fices allowing the circulation of water from one-

  tube to another. L.the tubes are connected to each other by welding around the orifices so that

  the end parts of the tubes, which are gener-

  flared, form an upper collector and a lower collector. Each collector has a

  tubular connection intended to be connected to a pipe-

  hot water. Hot water is supplied from

  firing from a central boiler towards the upper collector

  to be distributed in the emitter tubes and then collected in the lower collector after having transmitted a significant part of its heat to the emitters. The water then returns to the general piping

  by the connection of the lower manifold.

  Radiators of this type also include

  be in their upper part an air purge orifice and in their lower part an orifice for draining the water contained in the radiator during

its use.

  Known radiators have the disadvantage

  that a relatively large area of the tubes emits

  cannot be purged, which leads to "trapping of air with risk of corrosion, a reduction in the efficiency of the radiators and a risk of

  noise caused by water circulation.

  The object of the invention is to remedy these drawbacks and to provide a radiator having a more aesthetic appearance than that of known radiators.

  at the same time that it is space-saving.

  The subject of the invention is a radiator for

  central heating with several elements emits

  hollow torers arranged so as to form at least one row, the ends of the emitting elements being

  connected respectively to a first and a second-

  opposite collectors with communicating orifices

  as with corresponding orifices of the elements

  transmitters, the transmitting elements being fixed to the collars

  readers by welding around the orifices, characterized in that the collectors have a generally triangular contour, and that said communicating orifices of each collector are arranged in a part

forming an edge thereof.

  According to other characteristics of the invention

  managed in curved parts complementary to the emitting elements and the collectors; - the curved parts of the collectors are convex and the curved parts of the emitting elements are convex; - the curved parts of the collectors are convex and the curved parts of the emitting elements are also convex; the convex curved parts of the collectors cooperate with the curved parts

  convex of the emitting elements in a complementary way

  keep silent by the edges delimiting the communicating orifices

  quants; the collectors extend horizontally so as to constitute an upper collector and a lower collector, the upper collector is at its lower part connected to one of the emitting elements by means of a tubular connecting member forming a drainage conduit and the lower collector is at its upper part connected to one of the emitting elements by means of a tubular connecting member forming an air exhaust duct; - Each emitter element consists of a flat tubular body closed at its two ends by 'hollow elements forming end pieces welded to the tubular body; - Each collector has a generally triangular contour and one of its faces is arranged so as to be flush with the end faces of the emitting elements so as to form with them a flat surface.

  radiator according to another embodiment of-

  the invention. Figs. 1 to 5 show a radiator 1 according to

  a first embodiment of the invention. The ra-

  diator 1 comprises several flat tubes 2 constituting hollow emitting elements arranged vertically so as to form a row or battery. The elements

  2 transmitters are at their upper ends re-

  linked to a first collector 3 and at their lower ends connected to a second collector 4. The emitting elements extend according to this first embodiment parallel to each other in planes perpendicular to the collectors 3, 4 and are

fixed to them by their songs.

  Each collector 3, 4 is provided with a connector

  respective tubular cord 5, 6 intended to be connected to

  central heating piping (not shown).

  Each emitting element 2 is composed of a tubular body 7 closed at its two ends by

  hollow ends 8, 9 welded to the body (see Fig. 2 and 3).

  The body 7 has a generally trapezoidal outline and has, on a part of its inclined sides, slots communicating with corresponding slots made in the end pieces 8, 9, the edges of which

  defining the slots are embedded in the body.

  Each end piece 8, 9 has a generally trian outline

  gular. The manifolds 3, 4 also have a generally triangular contour and are preferably connected to the respective nozzles 8, 9 so that the radiator assembly has a configuration with

  roughly parallelepipedic and relatively compact.

  All edges of emitting elements and collectors are rounded (see for example the

  Fig. 3 to 5) -to prevent a person who hits-

  accidentally the radiator is injured.

  Each end piece 8, 9 has a curved part 10, 11 complementary to a curved part 12, 13 of the corresponding collector 3, 4. Holes 14 are formed in said curved parts 10, 11 of the ends 8, 9. The holes 14 , 15 communicate with corresponding orifices 16, 17 formed in parts forming rounded edges of the collectors 3, 4 in order to allow the circulation of water from the first collector 3 in the emitting elements 2 and

  then in the second header 4.

  The curved parts 10, 11 of the emitting elements 2 have, in the example illustrated in FIG. 2, a concave shape in order to cooperate with the corresponding curved parts 12, 13 of the collectors 3, 4,

  which have a complementary convex shape.

  The emitting elements 2 are fixed to the collectors 3, 4 by welding around the orifices 14 to 17.

  Each collector 3, 4 according to this feedback mode

  The reading is also connected to one of the transmitting elements.

  teurs 2 via a tubular connecting member forming a respective conduit 18, 19. The conduit 18 of the first collector 3 allows the evacuation of the water contained therein in the case where one wishes to empty the radiator. The conduit 19 of the second manifold 4 is intended for the air purging thereof

  when starting the radiator.

  The first manifold 3 further comprises an air purge orifice 20 (see FIG. 1) disposed near the upper face of the manifold in order to

  allow almost complete evacuation of the air em-

  trapped in the radiator during its installation. This orifice 20 is normally closed by a

shutter (not shown).

  The second collector 4 further comprises a

  drain port 21 disposed near the underside

  collector to allow evacuation

  practically total of the water contained in the radia-

  tor. This orifice 21 is also closed by a plug.

rator (not shown).

  Fig. 6 shows another embodiment

  according to which the emitting elements 2a are also

  ment arranged parallel to each other and fixed to the collectors 3 by their edges. Each end piece 9a has a curved part 10a which has a convex shape and which cooperates in a complementary manner with the curved part 12 of the first manifold 3 by the edges delimiting the communicating orifices formed in the emitting elements and in the collectors. The ends of the tubular body 7 are in the example illustrated in Fig.6 closed over their entire width by elongated parts 9b of the end pieces 9a. Fig.6 further shows how the first manifold 3 is connected to the end piece 9a by a

p> ge 18a.

  The second collector (not shown) is identical to the second collector in Fig. 2 and is connected to a nozzle having a shape similar to that of

the tip 9a.

  Another embodiment of the invention is illustrated in Fig.7. The radiator comprises two rows of emitting elements 2 similar to those already

  described with reference to Fig. 6. These elements emit-

  teurs are arranged on either side of a first

  collector 22 and a second collector (not shown

  felt) analogous to the first. The collectors have an isosceles triangle-shaped outline, the base of which faces upwards. Each collector 22 has near its surface facing outwards orifices 23 communicating with orifices 24 formed in the emitting elements near the surface

end of these.

  The collectors 22 comprise, as already described with reference to the first embodiment, two conduits forming tubular connecting members, one of which 18b is shown in FIG. 7, intended for

  allow the radiator to be drained and drained,

pectively.

  The radiator with two rows of emitting elements may, according to a variant not illustrated in the drawings, comprise two pairs of collectors of the type illustrated in FIG. 2 or 6. The collectors of

  each pair of collectors are in this case

  taggedly connected to each other by conduits allowing the circulation of water from one collector to another.

  Figs. 8 to 11 show modes of realization

  sation that the transmitting elements are distributed

  laid so as to extend in two parallel planes and they are fixed flat by their large faces, to the collectors. - Fig.8 is an overview of a radiator comprising two rows of hollow emitting elements 25 arranged on either side of a first and a second manifold 30, 31. The emitting elements are separated from each other in order to form between them gaps 26 allowing circulation

air between said elements.

  Fig.9 shows that each emitter element is composed of a flat tubular body 27 whose ends are closed by end pieces 28, 29 welded to the body. The tubular bodies 27 provided with end pieces 28, 29 have a generally parallelepiped shape. The edges of the end pieces 28, 29 are embedded in the

tubular body 27 (see Fig. 10).

  The emitting elements 25 are connected by their large faces to similar collectors 30, 31

  to the manifold 22 described with reference to Fig. 7.

  The emitting elements 25 have orifices 32, 33 communicating with orifices 34, 35 formed in the collectors 30, 31. The orifices 32 to

  35 are formed in curved parts complementary

  silences 36, 37 emitting elements and collectors

teurs, respectively.

  The collectors 30, 31 are further connected

  to a transmitting element 25 via an or-

  respective tubular connection gane 18c, 19c, intended to allow the radiator to be drained and drained, respectively. Fig.11 shows a variant of the embodiment described with reference to Figs 8 to 10. According to this variant, the collectors 30, 31 are arranged vertically and interconnected by emitter elements 25 arranged horizontally and extending in two parallel planes. It can be noted that according to this embodiment, there is no longer any need for tubular connecting members so that it is possible to purge

  and completely empty the radiator. Just pre-

  see an air purge orifice 20 and another orifice

21 water drain.

  In all the embodiments described with reference to FIGS. 8 to 11, it is naturally

  also possible to consider variants in which

  the emitting elements are arranged in a single

side of the collectors.
