Definitions
- the invention relates to a radiator with at least one, of a heat transfer medium flowed through hollow profile, which consists of a front wall and at least partially spaced rear wall, which are interconnected by two side walls to form a channel, and each with at least one inlet and one Drain for the heat transfer medium as described in the preamble of claim 1.
- Known radiator which are mainly used for space heating, usually consist of a flat sheet metal housing that is traversed by warm water and whose heat radiates through a corrugated sheet-like corrugated wall of this panel radiator.
- Such Thompsonköper is eg from the EP-A-1058070 , or the DE 297 18 876 U1 known.
- This has a part through which a flowing, heat-transferring medium flows and a heat-dissipating part, wherein the heat-transferring part is connectable to a pipe or the like leading to the flow medium.
- a flat profile containing a flow channels has clamping elements integrally formed on at least one outer surface for parts which can be connected to them as temperature-dissipating parts.
- the radiator ie its flat profile or the lamellar inserts, consist of a light metal alloy and are produced by extrusion.
- the flat profile consists of two spaced-apart profile walls and connecting them with the flow channels limiting, approximately parallel transverse walls. In order to create the largest possible heat-transmitting surface, short rib strips are formed on the inner surfaces within the channels of this radiator. Furthermore, depending on the required performance of the space heater several of these flat profiles can be arranged in alignment with each other.
- This object of the invention is achieved in that the distance between the front wall and the rear wall of the hollow profile is selected from a range with a lower limit of 1 mm and an upper limit of 5 mm.
- the radiator has so much small clear width, it was surprisingly found that despite this small flow cross-section, an improved heat exchange and thus improved heating performance is obtained. The reason for this is probably to be found in the fact that due to the small flow cross-section, at least a large part of the heat transported by the heat transfer medium heat is transferred to the walls bounding the flow channel, so so simplified, not unnecessarily heat in the circuit, as is the case with conventional central heating is, is transported.
- radiator Due to the reduced distance between the front and rear walls of the hollow profile is not only a more compact design of the radiator is possible and thus a less inconspicuous installation in a room to be heated, if necessary, this radiator can even be designed as a wall panel, but it is also the advantage to achieve that it responds very quickly and thus in a very short time, the space heating is possible.
- the distance between the front wall and the rear wall of the hollow profile is selected from a range with a lower limit of 2 mm and an upper limit of 4 mm, or according to another embodiment, this Distance 3 mm.
- the front wall can be arranged with the rear wall connecting at least one further web to form at least one further channel.
- a multi-channel system is created in the profile, whereby the flow cross-section of a single channel is further reduced and thus the heat transfer can be made more efficient and it is also possible through this training, with a corresponding connection of flow or return with only one hollow section a snake - or meandering flow through the radiator to produce.
- the at least one web can also the compressive strength of the hollow profile and thus the stability of the radiator can be improved.
- This at least one web can have a wall thickness selected from a range with a lower limit of 0.35 mm and an upper limit of 1 mm. Due to this very small wall thickness of the at least one web, heat transfer into the respective laterally adjacent channels is optionally possible, in particular in meandering flow guidance - in addition to the heat transfer by heat conduction into the room air - so that a homogenization of the temperature profile of the hollow profile can be achieved and thus also a correspondingly uniformed radiating surface of the radiator. This can be achieved so that the heat transfer from the "hot inlet” into the "cold drain” within a hollow section is made possible.
- the at least one web can have a wall thickness selected from a range with a lower limit of 0.4 mm and an upper limit of 0.8 mm, or the wall thickness of the at least one web can be 0.5 mm be.
- the channels are arranged directly next to one another in the hollow profile. Due to the side-by-side arrangement of the channels, these cover virtually the entire surface of the hollow profile, which is available for heat transfer and can thus be achieved with respect to this area a higher efficiency.
- the number of channels in the hollow profile can be selected from a range with a lower limit of 15 and an upper limit of 40, or according to a further embodiment thereof with a lower limit of 20 and an upper limit of 30, in particular, the number of Channels in the hollow section 24 amount.
- the response of the radiator can be further improved, in particular so that several channels can already be connected to the inlet, so that already at the inlet of the heat transfer medium in the radiator a correspondingly large area for heat transfer and thus a correspondingly high efficiency can be achieved ,
- the width of the channels is selected from an area with a lower limit of 1.5 mm and an upper limit of 5 mm, or if the width of the channels is selected from a range with a lower limit of 2 mm and an upper limit of 3, 5 mm and 3 mm, respectively the width of the channels is 2.2 mm, so that formed by this reduced flow cross section virtually no "core flow", which flows unused through the channels of the hollow profile.
- the width of the channels in the direction of the front wall is smaller than the distance of the front wall of the rear wall, as can be obtained correspondingly favorable flow conditions.
- the hollow profile may have a width selected from a range having a lower limit of 40 mm and an upper limit of 400 mm, or the width may be selected from a range having a lower limit of 80 mm and an upper limit of 250 mm , or the hollow profile may have a width of 100 mm, so that the radiator is adaptable to the desired heating power by the optional multiple arrangement of hollow sections in the radiator.
- the front wall is the back wall and the side walls to form a wall thickness, which is selected from an area with a lower Limit of 0.5 mm and an upper limit of 1.5 mm.
- the wall thickness of the front wall and / or rear wall and / or the side walls from a range with a lower limit of 0.75 mm and an upper limit of 1.2 mm or the wall thickness 0.9 mm.
- the heating power it is possible to vary the heating power to provide a plurality of hollow sections to form a channel system via manifolds fluidly connected to each other in the radiator.
- the flow connection can be made via the opposite open profile ends of the hollow sections, so that therefore additional Built-in hollow profile can be dispensed with.
- the flow connection can be designed so that the heat transfer medium flows through the channel system meandering, so that this travels the longest possible path through the radiator before it leaves this again through the flow and thus a correspondingly long period for heat exchange is available.
- front wall and the rear wall are arranged at least approximately parallel to one another, it is possible to form the channels at least approximately with the same flow cross section.
- the cross-section of the channels may be rectangular, square, round, trapezoidal, rhomboid, diamond-shaped or triangular, with mixed forms within a radiator are also possible, for example, to influence the flow behavior positively or to keep power losses due to the resulting pressure gradient as low as possible ,
- the hollow profile itself can be extruded, since it can be used on a standardized method for the production of hollow sections and the manufacturing costs can be reduced by a manageable mass production.
- the extrusion process in a simple manner, the hollow profile according to the invention with the small distance of the front wall of the rear wall with a correspondingly high dimensional accuracy and without much Nachbearbeitungsaufwand produce.
- By extrusion it is also possible to easily produce the hollow sections with virtually any length.
- the hollow profile has been subjected to deformation after extrusion to reduce the distance between the front and rear walls, in particular cold working, e.g. Pressing or rolling, as this allows the extruded hollow profiles in principle with a larger flow cross-section, i. greater distance between the front and rear walls and can be produced as a result of higher dimensional accuracy.
- said manifolds may be connected by at least one bend with the inlet and outlet, whereby the inlet or outlet in the rear region of the Schugropers, ie invisible from the visible side of the radiator can be arranged.
- the hollow profile is formed of aluminum or an aluminum alloy, since these materials are known for their high conductivity and thus the efficiency of the radiator can be further improved.
- Fig. 1 is a hollow section 1 for a radiator 2 (see, eg Fig. 7 ), which comprises a front wall 3, a rear wall 4 and two side walls 5, 6.
- the front wall 3 and the rear wall 4 are planar in this embodiment of the hollow profile 1 and at least approximately parallel to each other.
- the two side walls 5, 6 are formed at least approximately parallel to each other and planar.
- the inlet 7 and the outlet 8 can be arranged in only one of the side wall 5, 6 or it is also possible to arrange this inlet 7 and / or outlet 8 in the front wall 3 and / or rear wall 4 as needed.
- the hollow profile 1 is provided with only one channel 9, in which the heat transfer medium of this hollow profile 1 flows through, while the heat, which in a heat source, e.g. a burner boiler according to the prior art, is transmitted to the front wall 3 and / or rear wall 4 and / or the side walls 5,6,
- a heat source e.g. a burner boiler according to the prior art
- the hollow profile 1 is preferably made of a material, in particular metal, formed with high thermal conductivity, in particular it consists of aluminum or an aluminum alloy.
- the hollow profile can thus be made very light, for example, have a weight which is selected from a range with a lower limit of 0.5 kg / m and an upper limit of 0.75 kg / m, for example, the weight 0.66 kg / m.
- radiator 2 By using an aluminum material for the radiator 2, this is relatively easy. In addition, it has a fast response, so that after a short time a correspondingly large amount of heat has been transferred to the room air. Furthermore, it is possible with the radiator 2 according to the invention, in particular since its clear width, so the flow cross-section, is relatively low to heat the heat transfer medium to a higher temperature, since the registered heat is transferred very quickly into the aluminum material and thus introduced into the room air , By this rapid response, it is possible to dispense with conventional, known from the prior art slats to increase the heat-transmitting surface, although these can of course be arranged.
- a distance 10, ie in this case the clear width of the channel 9, is relatively small, in particular selected from a range with a lower limit of 1 mm and an upper limit of 5 mm. It is thus achieved a very small flow cross-section for the heat transfer medium, so that this evenly transfers its heat to the surrounding the channel 9 front wall 3, rear wall 4 and side walls 5, 6 and thereby in the heat transfer medium itself substantially inside no central Flow is formed, in which the heat is practically unused by the heat transfer medium in circulation. To avoid this, theoretically there is the possibility of making the radiator 2 over a large area, so that therefore a long flow path through the channels 9 of the radiator 2 must be covered and thus the heat can be transferred from these central areas to the corresponding walls.
- radiator 2 In the case of the radiator 2 according to the invention, this is not necessary, so that this radiator 2 can be made relatively compact and thus at least approximately constant heating power compared to radiators from the prior art, the formation of a radiator 2 is possible in a room practically in the background occurs.
- this hollow section 1 is produced by extrusion of aluminum or an aluminum alloy. This has the advantage that it can be used to produce a hollow profile 1 with very thin walls, so that in turn the heat transfer, i. the heat exchange from the heat transfer medium to the ambient air surrounding the radiator 2, is made possible.
- the front wall 3 and / or rear wall 4 and / or the two side walls 5, 6 has a wall thickness 11 which is selected from a range with a lower limit of 0.5 mm and an upper limit of 1.5 mm.
- this wall thickness 11 can be further reduced, in particular selected from a range with a lower limit of 0.75 mm and an upper limit of 1.2 mm.
- the wall thickness 11 for the front wall 3 and / or the rear wall 4 and / or the two side walls 5, 6 preferably has a wall thickness of 0.9 mm.
- the hollow profile 1 should be self-supporting, that is to say should have a certain strength, a reduction of the wall thickness 11 below 0.5 mm is not provided.
- the strength of the hollow section 1 to this extent not be required, for example, when the hollow section 1, a kind of cage, for example in the form of a grid, constructed, which takes on a strength by the carrying function and on the other hand, the hollow section 1 against the outside Shock and thus deformation of the same protects, of course, in the context of the invention, the wall thickness 11 be less than 0.5 mm.
- a further improvement of the heating capacity, ie the heat transfer, to achieve by further reducing this distance 10 takes a value from a range with a lower limit of 2 mm and an upper Border of 4 mm.
- this distance 10 between the front wall 3 and the rear wall 4 3 mm is a value from a range with a lower limit of 2 mm and an upper Border of 4 mm.
- the hollow profile 1 it is possible to produce the hollow profile 1 with a greater distance between the front wall 3 and the rear wall 4 than 5 mm. In this case, or to further reduce the distance 10, it is possible, the hollow profile 1 after the extrusion of a deformation, in particular a cold deformation, e.g. by pressing or rolling, to submit.
- a deformation in particular a cold deformation, e.g. by pressing or rolling
- the minimum distance is 1 mm. Below lying distances, ie clear widths of the hollow section 1, however, can be used when the pump power for the circulation of the heat carrier is correspondingly high.
- the metal from which the hollow profile 1 is produced is preferably made of an aluminum material, ie aluminum or an aluminum alloy. These materials are particularly suitable for producing hollow sections 1 by extrusion or cold forming.
- aluminum has the advantage of being more cost effective and substantially more corrosion resistant to iron than copper, which is commonly used in radiator construction.
- Fig. 2 a variant of the hollow profile 1 is shown.
- the channel 9 of the hollow profile 1 is after Fig. 1 split, in several individual channels 9, so that in the hollow section 1 at least two channels 9 are present.
- this web 12 is also produced simultaneously with the hollow section 1 by extrusion. Since the at least one web 12 has only a limited support function, it is possible to perform this with a smaller wall thickness 13, which may be selected from a Range with a lower limit of 0.35 mm and an upper limit of 1 mm.
- this wall thickness 13 is selected from a range with a lower limit of 0.4 mm and an upper limit of 0.8 mm or this wall thickness can be 0.5 mm.
- this at least one web 12 it is possible to divide the heat carrier to a plurality of channels 9, so that the flow cross-section is further reduced and thus heat transfer via these webs 12, which are connected to the front wall 3 and rear wall 4 and thus to initiate this heat in these channels 9, to allow.
- the heat transfer medium ie for example the heating water, serpentine or meandering to guide, so so for example, a first channel 9 for the upward flow of the heat transfer medium and another channel 9 for the downward flow of the heat transfer medium is used.
- This extends the flow path of the heat transfer medium in the hollow profile 1 and is therefore also a longer period of time for the heat exchange available.
- the webs 12 thus increase the heat transfer surfaces and thus improve the efficiency. For this it is thus possible to give the hollow section 1 a higher pressure resistance and the radiator 2 with a higher operating pressure, which can reach up to several bar operate.
- the two side walls 5, 6 need not be flat, but may for example also have a curvature.
- the front wall 3 and / or the rear wall 4 have such a curvature, so that, for example, the maximum distance of 5 mm between the front wall 3 and the rear wall 4 is achieved only in the central region of the hollow section 1 and in the two side areas of the two side walls 5, 6, the channels 9 have smaller clear width.
- an increase in the flow cross-section in the center region of the hollow profile 1 can be deliberately formed in order to vary, for example, the flow resistance within the hollow profile 1 or to design the flow profile such that the flow resistance over the hollow profile 1 is at least approximately constant within narrow limits.
- the variation of the size of the flow cross-section within a hollow section 1 or the Radiator 2 is generally for all embodiments of the invention, a way to influence the flow resistance.
- the hollow profile 1 provided for a radiator 2, in particular a flat radiator, preferably has a width 14 selected from a range with a lower limit of 40 mm and an upper limit of 400 mm. This makes it possible to provide a plurality of channels 9 in the hollow section 1 - if equal to this width 14 of the hollow section 1 is also appropriate if only one channel 9 is provided in this - so as to pretend a corresponding flow of the heat transfer medium in the hollow section 1. However, this width 14 may be further selected from a range having a lower limit of 80 mm and an upper limit of 250 mm and 100 mm, respectively.
- only one channel 9 can be formed in the hollow profile 1.
- the adjacent channels 9 cover virtually the entire radiator surface or hollow profile surface. This is a very high efficiency of the radiator 2 can be achieved.
- a width 15 of the channels 9, ie the lateral distance between the webs 12, is selected from a range with a lower limit of 1.5 mm and an upper limit of 3 , 5 mm.
- the width 15 of the channels 9 from a range with a lower limit of 2 mm and an upper limit of 3 mm and the width 15 of the channels 9 on the order of 2.2 mm choose.
- the heat-radiating surfaces are either the front wall 3 or the rear wall 4 or the side walls 5, 6, ie those walls which communicate with the ambient air, if the width 15 of the channels 9 is smaller, as the distance 10 of the front wall 3 of the rear wall 4, since ultimately the transmitted heat in the webs 12 must also be forwarded in these outer walls.
- the cross section of the channels 12 can be chosen arbitrarily, that is, for example, rectangular, square, round, trapezoidal, rhomboid, diamond-shaped or triangular and is for this purpose in Fig. 3 in order to clarify this, hinted another variant of the hollow section 1 in plan view.
- This hollow profile 1 consists essentially of a Sequence of erected squares, in particular squares, wherein the connection of the individual squares takes place via the corners, so that therefore the cross section of the channels 9 is also quadrangular or square.
- the front wall 3 and the rear wall 4 are not formed in this embodiment of the hollow profile 1 by planar walls, but have this in cross-section, zigzag-shaped course.
- the distance 10 of the front wall 3 of the rear wall 4 of that distance 10 which is formed between two opposite corners. This distance is reduced after the channels 9 are connected to each other via the corners to zero and then increase again to the maximum value. In this sense, the definition of this distance 10 is to be understood in the context of the invention.
- Fig. 3 Dashed is in Fig. 3 indicated that in this variant of the hollow section 1, the channels 9 just described outside of a front wall 3, a rear wall 4 and the side walls 5, 6 may be limited, according to the embodiment according to Fig. 1 , Preferably, the previously described the distance 10 as defining described opposing vertices connected to these walls.
- this structure can also be produced by extrusion. It is also conceivable that these corners are connected via, for example, welds with the individual walls. It is thus possible, in addition to these square or rhombic channels 9 in the edge regions of the hollow section 1 further channels 9 form with triangular cross-section, so that this hollow section 1 has a plurality of individual channels.
- the still relatively hot heat transfer medium flows in one direction and flows in the outer channels 9 with triangular cross-sections already cooled heat transfer medium against the still hot heat transfer medium, so again in turn a serpentine or meandering flow is achieved within a hollow section 1.
- This is the heat transfer from the hot heat transfer medium on the one hand in the walls of the hollow section 1 and on the other hand in the already cooled heat transfer medium in the triangular channels 9, so that heat can still be delivered to the environment via this detour.
- This cross-sectional shape has a particularly high stability and is therefore also suitable for higher operating pressures of a heating system.
- Fig. 4 shows the arrangement of four hollow sections 1 for forming a radiator 2.
- the individual channels 9 are in fluid communication with each other, wherein the individual hollow sections 1 can be connected to each other, for example via pipes 16.

- FIG. 4 This arrangement of several hollow sections 1 after Fig. 4 represents only one of the possible embodiments and can also be arranged more than four or less than four hollow sections 1 in the radiator 2. In extreme cases, the radiator 2 may comprise only a hollow profile 1.
- Fig. 5 should only be clarified that it is of course also in the hollow section 1 according to the invention, ie a radiator formed therefrom, according to the prior art, so-called fins 17 to increase the heat-emitting surface on one of the walls of the hollow section 1, so for example the Rear wall 4 to arrange. It is also a centric arrangement of the hollow section 1 in the radiator 2 is possible, so that therefore the hollow section 1 viewed in cross-section is surrounded on all sides by such fins 17. In this case, it is advantageous if the radiator 2 has at least one outer lining element in order to avoid direct inspection of the inner structure, in particular the lamellae 17, provided that they have a visually disturbing effect.
- a manifold 18, for example with a rectangular cross-section.

- the execution of a radiator 2 after Fig. 8 are the hollow sections 1 - although only three hollow sections 1 are shown, it is of course possible to arrange more or less of these hollow sections 1 in the radiator 2 - in contrast to the embodiment according to Fig. 7 not aligned at least approximately parallel to the feed line 19 and the discharge line 20, but at least approximately perpendicular thereto.
- a distance 22 between the individual hollow profiles 1 can be chosen so that between the hollow profiles 1 a kind of forced convection is formed, so which these hollow sections 1 are flowed around by the surrounding room air and thus a better heat transfer through the inflowing from below cooler air and thus An increase in the efficiency is possible.

- the corrugation is not provided with curves, but that the wave crests are connected with straight lines, or are hybrids of curves and straight lines possible.
- the radius of the rounding can be adapted to the respective requirements, or may have a rounding several different radii.
- the width 14 of the hollow profile 1 after Fig. 12 is for example 120 mm.
- the width 15 is 4.3 mm.
- the wave crests can, for example, rise by 1.4 mm over the wave troughs, whereby a variation of wave height in the range between 0.75 mm and 3 mm is possible here.
