Abstract
Description
Title of the invention: Electric inertial fluid radiator technical field
[0001] The present invention relates to the field of building construction, in particular the heating of zones within a building. Specifically, the invention relates to an electric radiator with an inertial fluid. Previous technique
[0002] To comfortably heat an area of a building, in particular a room, it is known to use a dry inertial mass or a fluid inertial mass associated with a radiator.
[0003] In the case of a fluid-filled inertial mass radiator, it is known to heat a heat transfer fluid, for example water or oil, in a closed cavity using a heating element located inside the cavity. This technique allows for good heating of the fluid. However, the fluid temperature rise is slow, which prevents the radiator from being highly responsive or providing an immediate feeling of comfort. Furthermore, manufacturing the cavity is complex because the heating element inside the cavity must be electrically connected to the outside via a sealed connector.
[0004] It is also known from FR2997167 to place a radiant panel between the closed cavity and the wall of a room, or between two closed cavities. The placement of the radiant panel simplifies the manufacture of the radiator, but does not allow for significant radiator responsiveness, nor does it provide an immediate feeling of comfort. Description of the invention
[0005] There is a need for an inertial fluid radiator with significant responsiveness in terms of heating and feeling of comfort, while having a simple structure. Summary of the invention
[0006] The present invention addresses this need by means of, according to one of its aspects, an electric inertial fluid radiator for heating an area of a building comprising:
[0007] - an outer casing comprising a front facade and a rear facade intended to be opposite a wall, the outer envelope having at least one inlet opening and at least one outlet opening to allow air circulation through the outer envelope;
[0008] - at least one internal structure mounted between the front and rear facades and comprising a closed cavity, the cavity being at least partially filled with a heat transfer fluid;
[0009] - a heating element mounted on the outer casing between the front face and said at least one internal structure and / or under said at least one internal structure between the front facade and the rear facade, the heating element being separated from said at least one internal structure by a non-zero space, the heating element being configured to heat air between the front facade and the rear facade.
[0010] In the present invention, the fact that the heating element is located between the front panel and at least one internal structure and / or under said at least one internal structure between the front and rear panels allows the front panel to be heated rapidly by radiation and provides a sensation of rapid warmth on the front panel after the heating element is switched on. This occurs in parallel with the temperature rise of said at least one internal structure and the heat transfer fluid, and with the creation of air convection between the area and the inside of the outer casing. The radiator thus exhibits good responsiveness to ignition, while benefiting from the advantages of an inertial fluid radiator.
[0011] By "the heating element being separated from said at least one internal structure by a non-zero gap", it is understood that the heating element is at a distance from said at least one internal structure, without being in contact with it. In other words, an air gap is present between the heating element and said at least one internal structure.
[0012] The heating element can be configured to heat said at least one internal structure by radiation and / or by convection.
[0013] The building area is preferably a room in the building.
[0014] The heating element can extend in a vertical plane when the rear face of the radiator is mounted on a vertical wall.
[0015] The closed cavity forms a reservoir of heat transfer fluid. This heat transfer fluid is also called an "inertial fluid" because its function is to accumulate a portion of the thermal energy generated by the heating element when the latter is activated and to release all or part of this portion of thermal energy when the heating element is deactivated.
[0016] Said at least one internal structure may extend in a vertical plane, in particular parallel to the vertical plane in which the heating element extends.
[0017] When the heating element is mounted on the outer casing under said at least one internal structure between the front and rear facades, the heating element and said at least one internal structure may extend in the same plan, in particular the same vertical plane. This allows, for example, to reduce the size of the radiator.
[0018] Said at least one internal structure may be perforated.
[0019] Said at least one internal structure may comprise a plurality of tubes, particularly between 2 and 20 tubes. The use of tubes increases and optimizes convective heat exchange with the air.
[0020] The closed cavity can be heard in each of the tubes, in particular in such a way as to form a single closed cavity.
[0021] Said at least one internal structure may comprise two main tubes and secondary tubes, the secondary tubes extending between the two main tubes.
[0022] The main tubes can be parallel to each other.
[0023] The secondary tubes can be parallel to each other.
[0024] The spacing between the secondary tubes can be variable.
[0025] The secondary tubes can be grouped into groups of tubes, the tubes in the same group having a constant spacing between them, the spacing between two groups being greater than the spacing of the tubes in the groups.
[0026] The heat transfer fluid can be water, glycol water or oil.
[0027] Said at least one internal structure may be metallic, in particular made of steel or aluminum.
[0028] Said at least one internal structure may be at a non-zero distance from the front facade and / or the rear facade.
[0029] The radiator may include at least one heating element fixing extending between the rear face and the heating element.
[0030] Said at least one internal structure may include a through opening, said at least one fixing extending through the through opening.
[0031] The heating element may include a resistive, convective and / or radiant element.
[0032] The heating element can be configured to cause convection between the openings in the outer casing.
[0033] The outer casing may include a grid in a lower part, an upper part, and / or on the front face.
[0034] The heating element can be configured to heat the building area by radiation and / or conduction.
[0035] The radiator may comprise a single internal structure having one or more cavities.
[0036] Alternatively, the radiator may comprise several internal structures. This can facilitate weight distribution, particularly when the heating element has a high power output. Indeed, in such a case, a single internal structure would be very cumbersome. bulky and therefore of significant mass. Subdividing it into several internal structures thus aids mechanical integration by facilitating the transfer of mechanical stresses. Brief description of the drawings
[0037] The invention will be better understood upon reading the detailed description that follows, the non-limiting examples of its implementation, and upon examination of the accompanying drawing, in which
[0038] [Fig-1] illustrates, in front view, schematically, an example of a radiator according to the invention,
[0039] [Fig.2] illustrates, schematically, in front view, the radiator of [Fig.1] without a front panel, and
[0040] [Fig.3] illustrates, in front view, schematically, another example of a radiator according to the invention without a front face. Detailed description
[0041] In the following description, identical elements or elements with identical functions bear the same reference numeral. For the sake of brevity, they are not described opposite each figure; only the differences between the embodiments are described.
[0042] In the figures, the actual proportions have not always been respected, for the sake of clarity.
[0043] Figures 1 and 2 illustrate an example of a radiator 1 according to the invention for heating an area of a building.
[0044] In this example, the radiator 1 extends in a vertical plane P when mounted on a wall and has a general parallelepiped shape.
[0045] The radiator 1 comprises an outer casing 2, a front face 3, illustrated only in [Fig.1], and a rear face 4 intended to be mounted on a wall.
[0046] The outer casing 2 can be made of a metallic material, for example aluminium.
[0047] The outer casing 2 has in a lower part an opening 5 in the form of a grid and in an upper part an opening 6 partially obstructed by blades.
[0048] The radiator 1 also includes an internal steel structure 10 having a closed cavity filled with glycol water.
[0049] The internal structure 10 is in this example fixed using fastener 11 on the rear face 4.
[0050] The internal structure 10 extends in a plane parallel to plane P.
[0051] The internal structure 10 comprises two main tubes 12 extending horizontally and having a substantially rectangular cross-section.
[0052] The internal structure 10 also includes secondary tubes 13 extending vertically between the main tubes 12 and having a substantially circular cross-section.
[0053] In this example, the diameter of the secondary tubes 13 is identical.
[0054] In this example, the closed cavity extends inside all the main tubes 12 and secondary 13. Preferably, the closed cavity is unique.
[0055] The secondary tubes 13 are grouped into groups 14, one of the groups 14 comprising three secondary tubes 13, another group 14 five secondary tubes 13 and a last group 14 a single secondary tube 13.
[0056] In groups 14 with several secondary tubes 13, the spacing between the secondary tubes 13 is constant, for example less than the diameter of the secondary tubes 13.
[0057] The spacing between the groups 14 is greater than the diameter of the secondary tubes 13, in particular at least twice greater.
[0058] The radiator 1 also includes, between the front face 3 and the internal structure 10, a heating element 20 in the form of rectangular plates 21.
[0059] The plates 21 are formed of a heating wire embedded in a metallic body, for example aluminium.
[0060] The heating element 20 extends in a plane parallel to plane P and is spaced at a non-zero distance from the internal structure 10.
[0061] For example, the heating element 20 extends over a width greater than the width of the internal structure 10.
[0062] The heating element 20 is fixed to the rear face 4 by means of fasteners 22, in this example four, which pass through the internal structure 10 at the spacing between the groups 14.
[0063] The radiator 1 also includes a control unit 25.
[0064] When the radiator 1 is switched on, the heating element 20 will produce radiation on the front face 3 which provides a feeling of warmth and comfort.
[0065] Furthermore, the air present between the facades 3 and 4 will be heated by contact with the heating element 20 or by its radiation. This causes convection between the grille 5 and the opening 6, which allows both the area of the building to begin heating and the internal structure 10 to be heated, which will in turn heat the fluid in its closed cavity.
[0066] A variant of radiator 1 according to the invention has been illustrated in [Fig.3].
[0067] In this variant, the internal structure 10 and the heating element 20 extend in the same vertical plane V, the heating element 20 being under the internal structure 10 and always at a distance from it.
[0068] This configuration allows for a reduced footprint compared to the embodiment shown in Figures 1 and 2.
[0069] In this example, the internal structure 10 includes channels, not shown, to ensure good circulation between the grid 5 and the opening 6.
[0070] The invention is not limited to the examples just described.
[0071] In particular, the internal structure could be different, for example solid.
[0072] The internal structure 10 may include several cavities, for example between 2 and 5.
