Description

Title of the invention: Electric radiator with inertial fluid Technical field

[0001] The present invention relates to the field of construction, in particular the heating of areas of a building. In particular, the invention relates to an electric radiator with inertial fluid. Prior art

[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 inertial mass radiator, it is known to heat a heat transfer fluid, for example water or oil, in a closed cavity using a resistor arranged inside the cavity. This technique allows good heating of the fluid. However, the temperature rise of the fluid is long, which does not allow for significant reactivity of the radiator, nor for an immediate feeling of comfort. In addition, the manufacture of the cavity is complex because the heating element, inside the cavity, must be electrically connected to the outside by a sealed connector.

[0004] It is also known from FR2997167 to arrange a radiant panel between the closed cavity and the wall of a room, or between two closed cavities. The arrangement of the radiant panel makes it possible to simplify the manufacture of the radiator, but does not allow for significant reactivity of the radiator, nor for an immediate feeling of comfort. Statement of the invention

[0005] There is a need for an inertial fluid radiator with significant responsiveness in terms of heating and comfort, while having a simple structure. Summary of the invention

[0006] The present invention meets this need thanks to, according to one of its aspects, an electric radiator with inertial fluid for heating an area of ​​a building comprising:

[0007] - an outer envelope comprising a front facade and a rear facade intended to be opposite a wall, the outer envelope comprising 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 facade and the rear facade 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 between the front facade and said at least one internal structure and / or under said at least one internal structure between the front facade and the rear facade makes it possible to heat the front facade quickly by radiation and to have a rapid sensation of heat on the front facade after the heating element is switched on, in parallel with the rise in temperature of said at least one internal structure and the heat transfer fluid and the provocation of air convection between the area and the interior of the outer casing. The radiator thus has good reactivity upon 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 space", it is meant 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 may be configured to heat said at least one internal structure by radiation and / or by convection.

[0013] The building area is preferably a room of the building.

[0014] The heating element may 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 otherwise called “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 restore 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 facade and the rear facade, the heating element and said at least one internal structure can extend in the same plane, especially 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, especially between 2 and 20 tubes. The use of tubes makes it possible to increase and optimize convective heat exchanges with the air.

[0020] The closed cavity can be understood in each of the tubes, in particular so 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 may 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 may 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, glycolated water or oil.

[0027] Said at least one internal structure may be metallic, in particular 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 comprise at least one attachment of the heating element extending between the rear face and the heating element.

[0030] Said at least one internal structure may comprise a through opening, said at least one fastener extending through the through opening.

[0031] The heating element may comprise a resistive, convective and / or radiant element.

[0032] The heating element may be configured to cause convection between the openings of the outer casing.

[0033] The outer casing may include a grille in a lower portion, an upper portion, and / or on the front facade.

[0034] The heating element may be configured to radiantly and / or conductively heat the area of ​​the building.

[0035] The radiator may comprise a single internal structure comprising one or more cavities.

[0036] Alternatively, the radiator may comprise several internal structures. This may facilitate weight recovery, particularly in the case where the heating element is of high power. Indeed, in such a case, a single internal structure would be very bulky and therefore of significant mass. Subdividing into several internal structures thus helps with mechanical integration by facilitating the absorption of mechanical forces. Brief description of the drawings

[0037] The invention may be better understood by reading the detailed description which follows, non-limiting examples of its implementation, and by examining the attached drawing, in which

[0038] [Fig-1] illustrates, in front view, schematically, an example of a radiator according to the invention,

[0039] [Fig.2] illustrates, in front view, schematically, the radiator of [Fig.l] without front panel, and

[0040] [Fig.3] illustrates, in front view, schematically, another example of a radiator according to the invention without a front panel. Detailed description

[0041] In the remainder of the description, elements that are identical or have identical functions bear the same reference sign. For the sake of brevity in this description, they are not described with reference to each of the figures, only the differences between the embodiments being 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] The radiator 1 extends in this example 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 comprising a front panel 3, only illustrated in [Fig.l], and a rear panel 4 intended to be mounted on a wall.

[0046] The outer casing 2 may be made of a metallic material, for example aluminum.

[0047] The outer casing 2 comprises 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 comprises an internal structure 10 made of steel comprising a closed cavity filled with glycolated water.

[0049] The internal structure 10 is in this example fixed using fixings 11 on the rear facade 4.

[0050] The internal structure 10 extends in a plane parallel to the plane P.

[0051] The internal structure 10 comprises two main tubes 12 extending horizontally and having a substantially rectangular section.

[0052] The internal structure 10 also comprises secondary tubes 13 extending vertically between the main tubes 12 and having a substantially circular section.

[0053] In this example, the diameter of the secondary tubes 13 is identical.

[0054] The closed cavity extends in this example 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 as great.

[0058] The radiator 1 also comprises, between the front facade 3 and the internal structure 10, a heating element 20 in the form of rectangular plates 21.

[0059] The plates 21 are formed from a heating wire embedded in a metal body, for example aluminum.

[0060] The heating element 20 extends in a plane parallel to the plane P and is spaced 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 facade 4 using fasteners 22, in this example four, which pass through the internal structure 10 at the level of the spacing between the groups 14.

[0063] The radiator 1 also comprises a control unit 25.

[0064] When the radiator 1 is switched on, the heating element 20 will produce radiation on the front facade 3 which provides a feeling of warmth and comfort.

[0065] In addition, the air present between the facades 3 and 4 will be heated in contact with the heating element 20 or by its radiation. This causes convection between the grid 5 and the opening 6 which makes it possible both to start heating the area of ​​the building and to heat the internal structure 10, which will itself heat the fluid in its closed cavity.

[0066] [Fig. 3] illustrates a variant of radiator 1 according to the invention.

[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 reduced bulk compared to the embodiment of Figures 1 and 2.

[0069] In this example, the internal structure 10 comprises channels, not shown, making it possible to guarantee good circulation between the grid 5 and the opening 6.

[0070] The invention is not limited to the examples which have just been described.

[0071] In particular, the internal structure could be different, for example solid.

[0072] The internal structure 10 may comprise several cavities, for example between 2 and 5.
