Description
- The present invention concerns a heating device, advantageously but not exclusively for domestic use.
- In particular, 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.
- Heating devices are known, in particular to heat a domestic environment or an office, a shop or in any case a closed environment.
- In particular, from the international application
WO-A-2006/070273 (WO'273) a radiator device is known, 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. - To increase the heating surface, 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.
- However, 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.
- Another limit concerns the upper part of the radiator which, with this disposition, results in the air coming from the rear part, toward the upper part of the radiator, causing a limited circulation of the air.
-
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.
- Moreover, 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.
- The present invention is set forth and characterized in the independent claim, while the dependent claims describe other characteristics of the invention or variants to the main inventive idea.
- In accordance with the above purposes, 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.
- A pipe containing heat-carrying fluid, such as water, oil or other fluid suitable for the purpose, passes through each module of the radiator and has at the upper and lower ends suitable collectors for communication between one module and the other.
- 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. In particular, 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. Moreover, the entrances located at the lower part are disposed so as to accentuate the different quantity of air, favoring the rear channel. Furthermore, 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.
- According to one characteristic of the present invention, the lateral ribs, as well as increasing the heating surface, 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.
- According to a variant of the invention, the lower ends of 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.
- According to a variant, 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. In this case another channel is defined between the rear plate and the wall.
- Thanks to this configuration, 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.
- Moreover, due to the conformation of the exits, 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, according to the present invention, is such that the cold air moves more quickly than the air present in the front channel, thus removing less heat.
- According to a variant, 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.
- According to another variant, the fins are adjustable in pitch. Intervals can therefore be provided with regard to the adjustment amplitudes.
- According to another variant, 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.
- According to another variant, the fins are made of different material, for example plastic, rubber or other, with respect to the material with which the ribs are made.
- These and other characteristics of the present invention will become apparent from the following description of one form of embodiment, given as a non-restrictive example with reference to the attached drawings wherein:
-
fig. 1 is a perspective view of the heating device of the present invention; -
fig. 2 is a lateral view of an element offig. 1 ; -
fig. 3 is an enlarged detailed view of the upper part of the module offig. 2 ; -
fig. 4 shows the section from iv to iv offig. 2 , in which the detail of the shape of the oil channel present inside the module of the heating device according to the invention can be seen; -
fig. 5 shows, with a detail, a variant of the invention. - With reference to
fig. 1 , aheating 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 ofheating elements 11, preferably made of aluminum, identical to each other and disposed adjacent to each other. Eachheating element 11 comprises aheating 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 eachheating plate 12, on the side facing toward the wall. - An
upper pipe 16 and alower pipe 17 pass through theheating device 10 and contain the heat-carrying fluid, such as water or oil for example, which heats theheating device 10. - A
central body 20 is disposed vertically between theupper pipe 16 and thelower pipe 17 in correspondence to eachheating plate 12, so as to substantially occupy all the bulk widthwise of theheating 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 theheating device 10 into two main parts, that is, afront channel 21, defined between theheating plate 12 and thecentral body 20, and arear channel 22, defined between therear plate 27 and thecentral body 20. - A rear
central rib 26 is disposed inside therear channel 22, substantially aligned with the corresponding frontcentral rib 13 and joined to thecentral body 20 and therear plate 27. - A
conveying element 30 is disposed between thefront channel 21 and therear channel 22, and above theupper pipe 16. The conveyingelement 30 has a conformation such that, in its part that is at the front during use, it has acurved profile 31, suitable to convey the air coming from thefront 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 substantiallystraight profile 32, although inclined forward, suitable to direct the air coming from therear channel 22 upward and away from the wall. The conveyingelement 30 therefore defines two distinct and separate exits of the heated air, facing substantially upward and partly forward, a firstfront exit 33 and a secondrear exit 34, which allow the air coming respectively from thefront channel 21 and from therear channel 22 to come out. - In substantial correspondence to its upper end, and in proximity to the
first exit 33, theheating plate 12 has athicker 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 theheating device 10 and the air in the room. - Moreover, in correspondence to its upper end, the
rear plate 27 has adeflector 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 thelateral ribs fig. 2 ), that is, progressively shorter going toward the wall, in order to better convey the cooler air toward therear channel 22. - The
channel 51 in which the thermal fluid transits has a cross section substantially shaped like the number eight (fig. 4 ), with theend parts central part 54 with a reduced width. - This conformation of the
channel 51, together with the presence of the twoupper exit apertures front heating plate 12, its upperthicker part 39, the front and rear conformation of the conveyingelement 30, and thedeflector element 127 concur together to optimize the movement of the flows of conditioned air, and their expulsion into the surrounding environment, optimizing the subsequent heat exchange. - This optimization allows to obtain optimal results comparable to devices of the known type but with one element (module) less, so that, given the same thermal effects, the device according to the present invention allows to obtain a considerable saving in costs.
- According to the variant in
fig. 5 , a mean to divert the flow is disposed at thelower end lateral rib inclined rib inclined rib 48 forms an angle α with respect to thelateral rib 36. The angle α, in the case shown, is greater than an angle β which represents the angle of inclination of theinclined fin 49 with respect to thelateral rib 37. The angle β, in this case, is in its turn greater than an angle γ, which represents the inclination of theinclined fin 50 with respect to thelateral rib 38. Moreover, theinclined fin 48 is longer than theinclined fin 49, which in its turn is longer than theinclined fin 50. - This disposition of the lower ends 42, 43, 44 of the respective
lateral ribs inclined fins rear channel 22 of theheating device 10, as well as increasing, together with thelateral ribs - It is clear that modifications and/or additions of parts may be made to the
heating device 10 as described heretofore, without departing from the field and scope of the present invention. - For example, the
inclined fins - Moreover, the angles of inclination of the
fins lateral ribs - Furthermore, the
inclined fins lateral ribs - It is also clear that, although the present invention has been described with reference to some specific examples, a person of skill in the art shall certainly be able to achieve many other equivalent forms of device, having the characteristics as set forth in the claims and hence all coming within the field of protection defined thereby.
