Definitions

  • the invention relates to a modular ramp element according to the preamble of claim 1.
  • the invention also relates to a radiator for heating installation with a modular ramp element.
  • the invention relates to such radiators consisting of standardized parts, which have the advantage of times to use a small number of parts, which can be produced with high quality criteria for a reasonable price, and to allow forms of realization adapted to a number of aesthetic requirements and virtually unlimited techniques.
  • the first domestic radiators using standardized elements assembled were the radiators in melting.
  • Technical and mechanical properties of cast iron imposed very massive and unsightly forms.
  • temperature inequalities in the volume of radiators frequently caused leakage problems at the level of connections, as described in particular in EP-A-0 518 843.
  • stamped sheet steel radiators described in particular in GB-A-2.082.749 pose the problem of their continuous surfaces not very favorable to the flow air, noise, and also their resistance to large temperature variations.
  • EP-A-0 816 791 proposes a heating radiator formed of sections of aluminum ramps connected to tubes steel heatsinks, which does not solve the problems of temperature differences and due to variations in sections between the different elements, disturbs the flow of the heat transfer fluid.
  • Heat exchangers made up of elements of adjoining distribution ramps are known in particular by the EP-A-0 631 101 which was considered below as the closest state of the art.
  • the invention aims to put on the market radiators virtually eliminating problems inequality in the distribution of heat flows.
  • Another object of the invention is that, even in the case where such inequalities would occur, the radiator either able to make its effects negligible.
  • Another object of the invention is to produce modular radiators which allow, with a number of basic parts reduced, to cope with a large number of possibilities of adaptation.
  • the object of the invention is a ramp element modular for space heating radiator circulation of fluid, axially traversed by at least one distributor ramp segment, comprising means for connection to heat sink tubes and means for securing with at least one adjacent element, each ramp element comprising at least two segments of distributing ramps arranged in parallel, characterized in that these at least two segments being interconnected by chambers of clearable compensation.
  • the clearing house is made up of preferably by joining two cavities of shape and additional dimensions arranged on the end faces of two adjacent elements.
  • sealing means are arranged between two elements adjacent to the periphery of the two complementary cavities, preferably in a notch going around one of the cavities.
  • At at least one of the sealing means comprises a suitable element at least partially blocking the clearing house corresponding so as to limit the passage of fluid between at least two ramp segments.
  • the means of joining together with an element adjacent generally include at least one flange crossed by a longitudinal hole extending in a plane located between the axes of the distribution booms at each of the ends of the element and a member of bolts of corresponding dimensions accessible from outside.
  • the bolting member comprises for example a head with internal sides, a threaded rod, the piercing of a flanges of the element carrying a corresponding thread.
  • the distribution manifold may have a section elliptical or oval in shape.
  • the radiator advantageously comprises two sets ramp elements arranged in parallel, these elements of ramps and the corresponding dissipating tubes forming a tablecloth.
  • the radiator can include at least two layers arranged in such a way that their respective ramps form an angle between them, the end elements of two adjacent tablecloths being interconnected by pieces angles whose faces are able to cooperate with the faces end of the corresponding end elements.
  • the ramps are, in one embodiment, arranged along a vertical axis.
  • the hollow dissipating elements have advantageously sufficient mechanical characteristics to support objects to be dried.
  • the ramp elements include an even number of segments of ramp, a group of these segments being connected to the entrance of the radiator, another group of these segments being connected to the outlet of the radiator, sealing means being arranged in the clearing houses connecting the segments connected to these two groups.
  • the ends of these elements sink dissipators, hairpin, (or "U") being distinctly connected to each of these two groups of segments.
  • the radiator comprises at least one ramp end piece with a shape adapted to that of the end face of one of the ramp elements.
  • one of the end pieces supports a thermostatic valve seat extending to inside the cavity and a valve shutter thermostatic cooperating with said seat, the handle of said shutter being attached to the outside of said part end.
  • Figs. 1 and 3 are perspective views radiator rail elements according to the invention, double and triple ramp segments respectively.
  • Figs. 2 and 4 are perspective views with bursting radiators incorporating heads such as shown respectively in Figs. 1 and 3.
  • Fig. 5 is a perspective view of another embodiment of a radiator using elements head shown in Fig. 1.
  • Fig. 1 represents a head element 1 of radiator according to the invention.
  • This elongated element 1 includes two ramp segments 2, 4 arranged in parallel opening at each of their ends into cavities 5 formed in each of the end faces 6, 8 of item 1.
  • Element 1 is made in one piece from light metal, for example aluminum.
  • Hollow nipples 10 in the shape of a crown are aligned in parallel on one of the faces of element 1, the internal cavity of each of these crowns being in direct communication with the ramp segment 2, 4 corresponding.
  • the hollow nipples 10 form part of a simple connection device with elements heat sinks 12 such as the tubes shown in Fig. 2.
  • the outside diameter of these nipples 10 corresponds indeed substantially the inside diameter of the tubes 12 ce which allows a junction by nesting and welding or collage.
  • a gasket sealing (not shown) is arranged on the periphery of the cavity 5 of the face 6, for example in a groove 14 as shown in FIG. 1.
  • a chamber hermetic [5,5] called "clearing house” whose volume corresponds to twice that of the cavities 5; this room [5,5] connects with each other the ramp segments 2, 4 of the ramp elements 1 butted together.
  • the walls of the cavities 5 form a structure in box which rigidly connects the two segments of ramps 2, 4.
  • a rib (not visible in Fig. 1), of shape adapted to that of the groove 14 protrudes from to the end face 8 so as to be able to fit into the groove 14 when two ramp elements 1 are butted together, which prevents any relative transverse movement of these elements 1 butted.
  • Each end face 6, 8 is provided with means for connection to an adjacent element. As seen in the Fig. 1, two longitudinal holes 16, 18 allow the insertion of threaded elements (screws or bolts) securing two adjacent ramp elements 1.
  • One of these openings 16 is formed on a flange 20 projecting from the side face carrying the nipples 10.
  • the other hole 18 opens directly into the face standing.
  • the openings of one of the two end faces (6 or 8) are threaded.
  • the head of the threaded elements remains perfectly accessible even when the radiator is completely assembled.
  • the heat transfer fluid is therefore distributed between the different tablecloths and ramps in Tickelmann loops.
  • the configuration of the heads causes losses by itself very reduced loads since the throttles of section are reduced to a minimum. Consequently, the radiator spontaneously adopts a dissipation regime as close to the optimum as possible, without outside intervention.
  • the items 1 may include an appropriate number of parallel ramp segments.
  • Figs. 3 and 4 are shown elements with 3 ramp segments 2, 3, 4 and a radiator made from such elements 1.
  • the presence of the cavities 5 at the end of the elements 1 also allows several advantageous variants: designed elements of angular connections whose faces of end fit exactly on the end faces of two elements 1, allowing the realization of zig-zag ramps whose sheets 22 extending along intersecting planes. We thus has the possibility, always with the help of elements standardized, to produce a radiator extending so continues along the walls of a room, following partitions etc ...
  • Another advantage lies in the accessibility of cavities 5 forming the compensation chambers: it is possible, at will, interrupt the bypass which puts the segments of ramps 2, 4 in parallel in an element or a series elements using a partition tab 24 of which the dimensions correspond to the cross section of clearing house 5, 5. If necessary, this tongue 24 may be integral with the seal.
  • Inserting tabs 24 wisely arranged in the ramps 2, 4 allows the heat transfer fluid for complex circuits optimizing heat flow by adjusting pressure drops to each distribution node. It also allows you to play to certain ramp segments of the same element 1 of the roles separate. Thus, in FIG. 5, a first series of ramp segments 2 acts as an entry ramp for the heat transfer fluid, a second series ensuring the role of exit ramp.
  • the radiator shown in Fig. 5 includes bent hairpin heatsink tubes, making possible some particular decorative effects. Through elsewhere, the radiator of FIG. 5 can be supported only by its ramp, which solves the problems elongation of the dissipating tubes, under the effect of thermal expansion.
  • the radiator of FIG. 5, as well as those shown in Figs. 2 and 4, can be arranged as desired with the elements 1 extending vertically or horizontally without significantly affecting its performance. We can thus, taking into account the mechanical stresses involved, use the radiators of the invention as a dryer or heated towel racks in a bathroom.
  • Radiators made with elements 1 according to the invention have the advantage of having a very large area in contact with ambient air. They can therefore be very compact and / or use a heat transfer fluid at lower temperature than conventional radiators.
  • dissipative elements are represented here in the form of round tubes, it goes without saying that we can provide them with fins promoting dissipation heat or give them any shape you want.
  • the radiator rail elements of the invention make connections extremely possible compact: the ends of the ramps made up of these elements can be interconnected by pieces end in bowl 26 whose width does not exceed that end faces 6, 8. These end pieces 26 can already include threaded entries leading to a choice on the back, sideways or downwards of a radiator mounted, eliminating the need for connecting parts visible and minimizing the length of visible piping.
  • the installation of piping can also be simplified, the arrival and the heat transfer fluid outlet which can be provided from from two adjacent points.
