Definitions

  • the present invention concerns a heating device, advantageously but not exclusively for domestic use.
  • the invention concerns a device, such as a radiator consisting of a plurality of aluminum modules, to be attached to the wall of a room to be heated, for example in a house, an office, a shop or in any case an interior which needs heating.
  • a device such as a radiator consisting of a plurality of aluminum modules, to be attached to the wall of a room to be heated, for example in a house, an office, a shop or in any case an interior which needs heating.
  • Heating devices are known, in particular to heat a domestic environment or an office, a shop or in any case a closed environment.
  • a radiator device made of aluminum, suitable to be attached to a wall of a room in a closed environment.
  • the radiator described in WO'273 comprises a plurality of thin, oblong, heating plates, located one adjacent to the other.
  • a rectilinear rib is associated at the rear of each heating plate, along its main dimension of development.
  • An upper pipe and a lower pipe pass through the device and contain the heat-carrying fluid which heats the device.
  • WO'273 provides to shape the heating plates in order to make, by means of them, suitable profiles, and/or use lateral fins, attached inclined with respect to the central ribs.
  • the known device of WO'273 has some limits, a first of which concerns the conveying of the air in the rear part of the device. Indeed, the conformation and the disposition of the heating plates limit a more intense conveying of the cooler air in the rear part of the radiator.
  • EP 1471309 describes a heating device with the characteristics of the preamble of the main claim 1.
  • a purpose of the present invention is to obtain, in a heating device of the type mentioned above, a better conveying of the air to be heated in the rear part of the radiator, in order to keep the front part and the rear part of the heating device at suitable and differentiated temperatures, according to the regulations in this field.
  • Another purpose of the present invention is to cause the air coming from the rear part of the radiator, exiting from the upper part of the radiator, to have an exit direction such as to render the circulation of the air better and more efficient.
  • Another purpose is to prevent the walls getting dirty due to the flow of air exiting vertically toward the top.
  • Another purpose of the present invention is to obtain a heating device which is light and at the same time is esthetically pleasing.
  • Another important purpose of the present invention is to optimize the thermal flows, achieving a circulation such as to guarantee heating capacities that allow to obtain the same heat yield using a lower number of elements (modules) compared to current solutions.
  • the Applicant has devised, tested and embodied the present invention to overcome the shortcomings of the state of the art and to obtain these and other purposes and advantages.
  • a heating device such as a radiator, made of aluminum modules, according to the present invention, is suitable to be used to heat internal environments such as those of a house, an office or a shop etc., or in any case of any closed environment.
  • the radiator in its minimum form, comprises a heating element, substantially formed by a slightly curved heating plate, a central body, a rear plate, a plurality of lateral ribs which define a plurality of vertical air channels and a conveying element which defines at least two upper exits.
  • heat-carrying fluid such as water, oil or other fluid suitable for the purpose
  • the heating element can be assembled in a known way, by positioning it adjacent to other identical heating elements, or modules, so as to generate from three to six vertical channels per side, advantageously four.
  • at least a front channel and a rear channel are defined.
  • the channels and the walls defined by the lateral ribs, the heating plate and the rear plate are profiled to differentiate the quantity of air in transit.
  • the entrances located at the lower part are disposed so as to accentuate the different quantity of air, favoring the rear channel.
  • the exits located at the top are oriented to direct the heated air toward the room to be heated, and the cooler air upward and forward for a more efficient circulation of the air.
  • the lateral ribs are disposed scaled down to direct the flow of air toward the rear, that is, toward the lateral rib nearest the rear plate, so that the greatest flow is conveyed in the rear channel.
  • each lateral rib are provided with means to divert the flow, such as for example fins inclined with respect to the lateral rib, in order to convey the air in the desired way.
  • the inclined fins have lengths and inclinations which decrease toward the back of the radiator.
  • the lower end of the rear plate is aligned with the lower end of the nearest lateral rib in the case where the rear plate, during the use of the radiator, is close to the wall.
  • the lower end of the rear plate is scaled down in relation to the lateral ribs in the case where the rear plate itself, during use, is at a distance from the wall.
  • another channel is defined between the rear plate and the wall.
  • the air sent toward the front channel of the radiator moves at a slower speed, while the air sent toward the rear channel moves at a faster speed, thus getting less hot.
  • the air which arrives at the upper part from the rear part of the radiator accompanies and promotes the exit of the air coming from the front channel. This promotes the circulation of the air and improves the performance.
  • the rear channel is such that the cold air moves more quickly than the air present in the front channel, thus removing less heat.
  • the fins present on at least one end of the lateral ribs are adjustable, so as to be able to vary the entity and/or the direction of the air.
  • the fins are adjustable in pitch. Intervals can therefore be provided with regard to the adjustment amplitudes.
  • the fins are replaceable, both so that they can be cleaned and also so that they can be replaced depending on the different behavior of the radiator.
  • the fins are made of different material, for example plastic, rubber or other, with respect to the material with which the ribs are made.
  • a heating device 10 is shown, in this case a radiator to be attached to a wall, to heat a closed environment.
  • the heating device 10 comprises a plurality of heating elements 11, preferably made of aluminum, identical to each other and disposed adjacent to each other.
  • Each heating element 11 comprises a heating plate 12, at the front during use, in this case slightly curved and rounded toward the front, which constitutes a large part of the heating surface.
  • a rectilinear front central rib 13 ( fig. 2 ) is associated orthogonally to the surface of each heating plate 12, on the side facing toward the wall.
  • An upper pipe 16 and a lower pipe 17 pass through the heating device 10 and contain the heat-carrying fluid, such as water or oil for example, which heats the heating device 10.
  • the heat-carrying fluid such as water or oil for example
  • a central body 20 is disposed vertically between the upper pipe 16 and the lower pipe 17 in correspondence to each heating plate 12, so as to substantially occupy all the bulk widthwise of the heating device 10.
  • a rear plate 27, during use, is attached in a known way to the wall.
  • the central body 20 is disposed so as to divide the heating device 10 into two main parts, that is, a front channel 21, defined between the heating plate 12 and the central body 20, and a rear channel 22, defined between the rear plate 27 and the central body 20.
  • a rear central rib 26 is disposed inside the rear channel 22, substantially aligned with the corresponding front central rib 13 and joined to the central body 20 and the rear plate 27.
  • a conveying element 30 is disposed between the front channel 21 and the rear channel 22, and above the upper pipe 16.
  • the conveying element 30 has a conformation such that, in its part that is at the front during use, it has a curved profile 31, suitable to convey the air coming from the front channel 21 substantially forward, that is, in the opposite direction to the wall and toward the room to be conditioned; in its rear part it has a substantially straight profile 32, although inclined forward, suitable to direct the air coming from the rear channel 22 upward and away from the wall.
  • the conveying element 30 therefore defines two distinct and separate exits of the heated air, facing substantially upward and partly forward, a first front exit 33 and a second rear exit 34, which allow the air coming respectively from the front channel 21 and from the rear channel 22 to come out.
  • the heating plate 12 In substantial correspondence to its upper end, and in proximity to the first exit 33, the heating plate 12 has a thicker part 39 facing toward the inside, which restricts the transit channel of the air immediately before the exit, generating an acceleration which improves the heat exchange conditions between the heated air exiting from the heating device 10 and the air in the room.
  • the rear plate 27 has a deflector element 127 with a reduced angle, which gradually accompanies the air channeled into the rear channel toward the room to be conditioned, preventing it from exiting vertically.
  • a plurality of lateral ribs in this case three, respectively 36, 37, 38, are attached vertically and parallel to each other, at the sides of each central body 20.
  • the lower ends 42, 43, 44 of the lateral ribs 36, 37, 38 are disposed scaled down toward the rear ( fig. 2 ), that is, progressively shorter going toward the wall, in order to better convey the cooler air toward the rear channel 22.
  • the channel 51 in which the thermal fluid transits has a cross section substantially shaped like the number eight ( fig. 4 ), with the end parts 52 and 53 widened and the central part 54 with a reduced width.
  • a mean to divert the flow is disposed at the lower end 42, 43, 44 of each lateral rib 36, 37, 38, in this case a flat inclined rib 48, 49, 50.
  • the inclined rib 48 forms an angle ⁇ with respect to the lateral rib 36.
  • the angle ⁇ in the case shown, is greater than an angle ⁇ which represents the angle of inclination of the inclined fin 49 with respect to the lateral rib 37.
  • the angle ⁇ in this case, is in its turn greater than an angle ⁇ , which represents the inclination of the inclined fin 50 with respect to the lateral rib 38.
  • the inclined fin 48 is longer than the inclined fin 49, which in its turn is longer than the inclined fin 50.
  • This disposition of the lower ends 42, 43, 44 of the respective lateral ribs 36, 37, 38 and of the inclined fins 48, 49, 50 is suitable to better convey the cooler air in the rear channel 22 of the heating device 10, as well as increasing, together with the lateral ribs 36, 37, 38 themselves, the heating surface.
  • the inclined fins 48, 49, 50 can be provided adjustable, or can be replaceable.
  • angles of inclination of the fins 48, 49, 50 with respect to their lateral ribs 36, 37, 38 can be identical to each other or two can be identical and one different, or other possibilities.
  • the inclined fins 48, 49, 50 can be made of a different material than that of the lateral ribs 36, 37, 38.
