Definitions

  • the invention relates to a hot water central heating radiator according to the preamble of claim 1.
  • a radiator is known from DE-A-18 04 787.
  • Radiators comprising a series of emitting elements in the form of tubes arranged vertically and forming a row or battery.
  • the tubes are at their ends connected to each other and have intermediate parts narrowed so as to form elongated openings extending between the emitting elements in order to improve the circulation of air through the radiator.
  • the tubes have at their ends lateral openings allowing the circulation of water from one tube to another.
  • the tubes are connected to each other by welding around the orifices so that the end portions of the tubes, which are generally flared, form an upper manifold and a lower manifold.
  • Each manifold has a tubular connection intended to be connected to a hot water pipe. The hot water is supplied from a central boiler to 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 through the connection of the lower collector.
  • Radiators of this type also have 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.
  • radiators have the disadvantage that a relatively large area of the emitter tubes cannot be purged, which results in a trapping air with risk of corrosion, a reduction in the efficiency of radiators and a risk of noise caused by the circulation of water.
  • a central heating radiator of the type comprising several hollow emitting elements arranged so as to form at least a row, the ends of the emitting elements being connected respectively to a first and a second opposite manifolds, having a generally triangular outline and having orifices communicating with corresponding orifices of the emitting elements, the emitting elements being fixed to the manifolds by welding around the orifices.
  • the spacing between the two collectors is greater than the length of the emitter elements extending between these collectors, which facilitates the purging of the radiators by the absence of air retention zones in the emitter elements.
  • radiators do not have satisfactory aesthetic qualities in particular because the collectors protrude from the general volume delimited by all of the emitting elements.
  • the object of the invention is to remedy the drawbacks of bleeding a radiator and to provide a radiator having a more aesthetic appearance than that of known radiators at the same time as it is compact.
  • the subject of the invention is a central heating radiator of the aforementioned type characterized in that one of the faces of each collector is arranged so as to be flush with the end faces of the emitting elements so as to form therewith a flat surface. , and in that said communicating orifices of each collector are arranged in an edge portion thereof.
  • Fig. 1 to 5 show a radiator 1 according to a first embodiment of the invention.
  • the radiator 1 comprises several flat tubes 2 constituting hollow emitting elements arranged vertically so as to form a row or battery.
  • the emitter elements 2 are at their upper ends connected to a first collector 3 and at their lower ends connected to a second collector 4.
  • the emitter elements extend according to this first embodiment parallel to each other in planes perpendicular to the collectors 3, 4 and are attached to them by their songs.
  • Each manifold 3, 4 is provided with a respective tubular connection 5, 6 intended to be connected to a central heating pipe (not shown).
  • Each emitting element 2 is composed of a tubular body 7 closed at its two ends by hollow end pieces 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 formed in the end pieces 8, 9, the edges of which define the slots are embedded in the body.
  • Each nozzle 8, 9 has a generally triangular contour.
  • the manifolds 3, 4 also have a generally triangular outline and are preferably connected to the respective end pieces 8, 9 so that the radiator assembly has an approximately parallelepipedal and relatively compact configuration.
  • All edges of the emitting elements and the collectors are rounded (see for example Figs. 3 to 5) to prevent someone who accidentally hits the radiator from being 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, 15 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 collector 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 embodiment is further connected to one of the emitting elements 2 via a connecting member tubular 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 it is desired to empty the radiator.
  • the conduit 19 of the second manifold 4 is intended for purging the air thereof when the radiator is started.
  • 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 total evacuation of the air trapped in the radiator during installation. of it.
  • This orifice 20 is normally closed by a shutter (not shown).
  • the second collector 4 further comprises a drain orifice 21 disposed near the underside of the collector in order to allow practically total evacuation of the water contained in the radiator. This orifice 21 is also closed by a shutter (not shown).
  • Fig.6 shows another embodiment according to which the emitting elements 2 a are also arranged parallel to each other and fixed to the collectors 3 by their edges.
  • Each end piece 9 a has a curved part 10 a 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 9 b of the end pieces 9 a .
  • Fig. 6 further shows how the first manifold 3 is connected to the nozzle 9 a by a purge duct 18 a .
  • the second collector (not shown) is identical to the second collector in FIG. 2 and is connected to an end piece having a shape similar to that of the end piece 9 a .
  • the radiator comprises two rows of transmitting elements 2 similar to those already described with reference to FIG. 6. These emitting elements are arranged on either side of a first collector 22 and a second collector (not shown) similar 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 end surface thereof.
  • the manifolds 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 to allow the radiator to be purged and drained, respectively.
  • the radiator with two rows of emitter 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 advantageously connected one to the other by conduits allowing the circulation of water from one collector to another.
  • Figs. 8 to 11 show modes of realization according to which the emitting elements are arranged 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 25 are separated from each other in order to form between them interstices 26 allowing the circulation of air between said elements.
  • each emitting element 25 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).
