radiator

The invention relates to radiators with several, arranged in at least two levels, leading the heating medium Plate heating elements that are connected to one another at the back, allowing the medium to pass through.

• / 2 209820/0120

So-called sectional or ribbed radiators are predominantly used today Usually, the same heating ribs, which have openings at the top and bottom, are arranged next to one another and are connected to each other at the upper and lower passages, so that the heating medium is the whole Can fill radiators. Only radiators of different widths can be made from the same heating ribs or members by using an appropriate number of links. If you want different levels or different deep radiators, radiator sections of different heights and / or depths must be made accordingly and put together. Because of the diverse requirements in terms of size and heating capacity of the radiators A large number of different types of ribs must be manufactured and kept in stock, as there are possible variations with the same elements are only possible in the width of the radiator. As a result, manufacture and Storage relatively expensive. In the case of very long radiators, the internal connection of the links is also important Difficulty and only with considerable effort to manufacture.

The appearance of sectional radiators is different in many Cases do not meet the wishes and ideas of the users and interior designers, as the individual ribs are often annoying work or are inappropriate. Above all, the painting of the radiators in the installed state causes great difficulties and thus considerable costs, since the ribs, between which one can look in, have also been painted at the back Need to become. One therefore often uses radiator panels that cover the radiator. she on the one hand cause additional costs and on the other hand impair the heating effect. It is already

Sectional radiator created with smooth front surfaces been. However, these are relatively narrow and high. The construction principle of these radiators is the same the same as the usual ribbed radiators. When designing the shape, one is always tied to narrow, high elements has a large number of joints between the individual elements.

In addition, so-called panel radiators are known which have more or less flat or profiled front and back walls, said supply and discharge of the heating medium {usually carried out above and below at the side. These panel radiators can be made individually according to the respective size of the radiator in terms of width, height and depth. Larger series are only possible where radiators of the same size are required. However, since different sized heating surfaces are required for each room depending on its size, the insulation of its'. At least the heat output of plate radiators vary within certain limits to has already been proposed * beaten, a radiator, comprising a basic heating element which fills an existing surface or recess, on the back fitted with optional hinzususchaltenden in parallel or in part parallel circuit members, which are arranged in the same structural design as the parts of the basic heater behind it, these additional members being smaller than the basic body. The additional links are connected to the main radiator via welded connecting pipes. This

BATH ORIGINAL

The construction principle still requires a front panel radiator that fills the entire surface and enables If the radiators look the same, no variation in width and height, unless the production of complete, different sized panel radiators. The depth of this radiator is because of the Pipe connections considerable.

Sectional radiators can also only be manufactured to a relatively large minimum depth. Given the considerable construction costs and the endeavor to have as little dead space as possible in the building, especially in the manufacture of prefabricated buildings in which deep radiator niches cannot be provided, a special need for very flat radiators with a high heating capacity has developed. It must be taken into account that each radiator must be installed at a certain distance from the V / and due to the flow conditions, safety regulations and the like _fLr , ΰί, β, the desired depth of the radiator is between 40 and 70 mm, if possible even less . This can hardly be achieved with ribbed radiators and panel radiators individually equipped with additional heating elements.

The invention is primarily intended to avoid the aforementioned disadvantages, the advantages of known radiator systems are preserved as far as possible and, among other things, the advantages listed below are achieved; particular lies the invention the task underlying to create a radiator system, which with extremely flat design and use the same or similar individual elements in the modular system can be combined to form different heights and widths and radiators of different depths made from basic elements

enables

According to the invention it is provided that the radiator with a plurality of identical or similar, each occupying only part of the area to be filled, overlaps arranged, flat plate heating elements, which are connected to one another at overlapping points. The invention is based on the usual type of panel radiators that take up the entire surface in one piece, and dissolves this surface into a multitude of identical or similar elements. To connect this the same or similar elements, preferably lying in one plane, are arranged behind or in front of them offset, the same or similar plate heating elements are provided. Due to the staggered arrangement, the overlap Individual elements of the different levels. The connections are then provided at overlapping points in order to Carry out heating medium and ensure the cohesion of the radiator. Through the overlapped, staggered It is now possible to arrange the plurality of plate heating elements according to the grid dimension with multiples or fractions of the grid dimension not only to the side, but also to the top and so a myriad of To achieve variations in height, width, depth and even shape of the radiator, so that the radiator e.g. Windows can also be provided laterally or for the graphic design of a V / and surface step-shaped or arranged in any other way or staggered, for example, in the stairwell instead of a side panel can be provided.

In order to be able to use elements that are as completely identical as possible, a grid is used for radiators according to the invention.

system to which all elements correspond, the plate heating elements can also have various rear connections have, and this can expediently at the corner points of isosceles triangles or in particular of equilateral polygons. The structure is particularly simple and clear if you have plate heating elements used with connections that lie on the corner points of a square. The heating elements can also only have two rear connections. You can then either exclusively or in combination with plate heating elements can be used that have more than two connections, and thus allow an even more diverse design of radiators with irregular shapes and odd or only unfavorable grid systems and Numbers of connections too.

In order to avoid assembly and manufacturing tolerances and a cleaning between the elements to allow, one can expediently leave a plane between the edges of different plate heating elements Split.

With the same grid system and the same position of the connection points, the plate heating elements can have a variety of external elements Have shape. The system is particularly simple and clear when the outer edges of the plate heating elements run parallel to the connecting lines of the connection centers. The embodiments discussed below however, show many other possible arrangements as well. There can be equal and unequal distances to the different sides of the elements can be provided. The heating elements can also have a circular shape, completely independently whether two, three, four or six connections are available.

are seen

The connection of the individual elements can take place in many known ways, for example by welding together at the connection points or by screwing together. In particular for radiators that can be set up freely and are visible on both sides, if welding is not an option, nozzles or nipples will be used between the overlapping ones. Parts of the plate heating elements lying and are provided with right and left thread and allow a common screwing {.

If the arrangement of visible screw heads or the like does not interfere or the radiators are to be mounted in front of a wall, a type of connection is expediently provided in which the plate heating elements with at least one element extending through the front wall and the rear wall, with the lateral ones Medium outlet and inlet enabling channels or recesses provided screw stubs or screw plugs are connected, which are screwed into nuts or in threads cut into the walls, preferably in compressed g elements with lateral I-iediumsdurchlaß provided spacers are arranged and between the elements and outside Plug heads and / or nuts sealing washers are arranged. This arrangement allows screwing in completely different forms particularly well, since the grid does not have to be taken into account because of the number of right and left threads.

The embodiment of the Pig. 1 and 2 shows in a niche "N" in the wall 17 a radiator 60, which with ten the same plate heating elements 61 is constructed. The individual plate heating elements 61 have the width b and the height h, which are the same in the present case, so that square areas result. Between each Plate heating elements are formed in the S column view. The entire radiator 60 has the width B and

./10 209820/0120

the height H. In the depth it has the dimension TH. The individual plate heating elements 61 have the depth th. The plate heating elements 61 are arranged in the two planes E1 and E2, which are one behind the other.

The individual plate heating elements 61 have smooth square front walls 62 and, as can be seen from FIG. 1, profiled rear walls 63. These lie on top of one another and are welded to one another around the edges R. The rear walls 63 have four elevations 64 at the connection points A1, A2, A3 and A4. The connection points A lie on the corner points of a (square with the edge length r, which represents the grid dimension. Here, r ^ and r _{2 are the} same.

As Fig. 1 illustrates, the rear plate heating elements 61h are about to the front plate heating elements 61v about half, namely by a grid dimension r, offset. The grid dimension r and the edge length are b and h of the panels chosen accordingly that the connection points A fit together again as pass points of these modular elements. This results in the overlap points U on the individual plate heating elements 61. At these overlap points U, the connection points A are located on the elevations 64 provided, on which the plate heating elements are connected to one another at the rear and on which a passage of the heating medium from one plate heating element 61 into the other is made possible. The connection can for example be carried out by welding or screwing, as explained below. At the two side ends of the Radiators 60, the upper and lower rows are connected to one another by half-plate heating elements 65. These have the same structure, but only about half the width, namely b / 2 - S / 2, but full height h and only have two

209820/0120

Junction points A. They are related to the whole elements to be understood as elements of the same kind within the meaning of this description and the claims. The heating medium feed takes place via the pipe 66 and the valve 67 hidden behind the upper left plate heating element 61 » during the process at the lower right terminal A4 of the lower right plate heating element 61 via the Pipeline 68 takes place, which is connected with a simple angle. Open connection points A are made with threaded plugs locked. The necessary ventilation can be achieved using a specially designed threaded plug appropriate training.

As Fig. 1 illustrates, are between the heating elements Cavities Ka formed, which have a good chimney effect. In the middle area, the rear walls 65 are the Plate heating elements 61 drawn in to form these chimneys and to reduce the amount of water.

Because of the overlapping arrangement of individual, identical plate heating elements 61, which are each smaller than the entire area to be filled Bx H, and the connection transversely to the main direction of the radiator results in a very flat design of the radiator, in which the total depth TH in practice between about 35 and 50 mm can be held. With a Y'and spacing WA of 40 - 50 mm, the result is a niche depth ¹ SH of 75 - 100 mm. Nevertheless, a radiator with a large heating surface and an attractive exterior is possible. The pitch r can be, for example, 15 cm and the edge lengths b and h 29 cm each, so that a gap width S of 1 cm results. As FIG. 2 shows, the radiator 60 has a simple, attractively structured and large heating element facing the living room.

area for the emission of radiant heat. On the other hand it "has a good chimney effect inside, so that the Convection is flawless. When using the same or similar plate heating elements, variations the dimensions and the heating surface in a great variety.

The Pig. 3 shows how square plate heating elements 61v and 61h and half, i.e. rectangular heating elements 65 a previously unknown radiator shape can be built, in which under a window F the Heating elements are arranged in two rows one above the other, while further plate heating elements next to the window are arranged one above the other, these all in turn in turn by overlapping plate heating elements 61h, 65 are connected to each other.

Fig. 4 illustrates how a radiator is constructed in the shape of a staircase, this being at the same time as a side Cladding of a staircase 80 is arranged and so instead of a filling under the railing 81 in stairwells can be accommodated without taking up any other space.

Fig. 5 illustrates a further example of a previously unknown design for radiators that is made possible by the overlapping arrangement of the same plate heating elements 61. They are in the front level alternating two square plate heating elements 61 ν one above the other and one in the middle between them, while in the back row the overlapping plate heating elements 61h are each only in a middle one Run through the row. One such or another

./13 209820/0120

The combined arrangement of plate heating elements makes it possible to design entire wall surfaces in an interesting and visually appealing way. The radiator is not just a puncture element, but also a design element. Its front surfaces can also be laid out in different colors, and this can improve the spatial effect even more. In order to achieve an attractive appearance, radiator cladding is no longer necessary, and the resulting heat losses are eliminated. Numerous other combinations are possible in width and height by the use in certain grids to i plate connecting the heating elements, as it is also explained further in the following.

The new radiator can not only be varied in width and height, but also as required also in depth.

Pig. 6 shows how plate heating elements' are arranged in three levels E1, E2 and E3, the front plate heating elements 61v and the rear plate heating elements 61h being identical, while the plate heating elements 82 of the middle level E2 are constructed somewhat differently; and * although they consist of two at the edges zusammenge- R 'welded rear wall panels 63, as they are related to the panel heating elements 61 only at the back. The heating elements of the first and second level are not overlapped, but are arranged congruently, while only the plate heating elements of the third level E3 are arranged overlapping to the two front ones and thus ensure the flow of the heating medium and the cohesion of the entire radiator. The plate heating elements 82 of the second level E2 can, however, also overlap with those of the two

./H 209820/0120

-u-

other levels E1 and E3 be arranged.

The Pig. 7 also illustrates in a schematic plan view how identical and similar ones are applied to each pail Plate heating elements 61, 65 and 82 constructed from the same pressed parts in seven levels E1 to E7 with one another are combined into a particularly deep radiator. In this way, a particularly large heating output can be achieved. In this case, too, the heating elements of the six front levels E1 to E6 do not need one behind the other, as in the example shown to be arranged in an opaque manner, but can overlap alternately or in a different sequence.

8 shows that the heating elements 61 of a row are not necessarily all in one plane, but also in several Levels can be offset from one another. Connecting pieces 85 of different lengths are used here. aside from that the dimensions of the individual heating elements are different from one another, so that they are at their edges cover something.

Fig. 9 shows how a radiator with elements in four levels E1, from completely identical plate heating elements 61, E2, E3 »E4 is formed, with two consecutive groups only at the outer ends of the radiator are connected to one another via longer connecting pieces 85.

The system of the rear connection of the same and / or similar Platteriheizelemente enables how this a few examples show, so diverse designs of radiators with variations both in width and also in height and in depth, always the same

./15

209820/0120

large and in some cases even completely identical elements, or at least completely identical pressed parts of the elements can be used.

The Pig. FIGS. 10-16c illustrate in schematic sections through the connection points, such as the walls of FIG Plate heating elements can be designed in completely different ways and still use the same principle of assembly ns can be applied.

The embodiment of Fig. 10 differs {

from that of the Pig. 1, 2 and 9 in that at the edges R legs 86 are folded back at right angles, so that round edges 87 arise and injuries are avoided and the weld is not visible. For the Connections A are provided in the recesses 64 internally threaded nuts 88. Screw nipples are screwed into these. The screw nipples are alternately provided with right-hand and left-hand threads so that they can be screwed together to enable. It can also be screwed through from behind, as will be explained below.

In the embodiment of FIG. 11, the front f

Wall plate 89 is provided with stampings 90 in the edge area. So you can give the front wall greater stability and also generate a profile that corresponds to the respective design needs. The back panel 63 is provided at the connection points A with outwardly protruding externally threaded sockets 91, which in no detail The way shown are tightly welded and with screw sockets with right and left threads with the connections other elements are connected.

./16

209820/0120

The embodiment of FIG. 12 shows an intermediate piece with outwardly directed threaded bushings 91 »the in Similar rear wall parts 63 are attached, which are welded to one another at the edge R.

The embodiment of FIG. 13 shows how the edge areas R are bent at an angle of about 45 degrees. Here, too, there are connection pieces of different lengths 85 is provided so that the individual plate heating elements 61 are in several planes.

FIG. H shows how both the front wall 95 and the rear wall 96 of the individual plate heating elements 97 are arched in the middle area. The connection method is the same as in the examples described above.

The embodiment of FIG. 15 shows how the front wall and rear wall 99 are designed in the form of a part-circle as a whole, so that part-cylindrical plate heating elements 100 result. When using appropriately shaped, rear plate heating elements, partially spherical front Elements are designed.

The embodiment of FIG. 16 shows how the axes 101 of the connection points A are not perpendicular to the main plane E of the heating elements 101a, but are inclined at an angle thereto. The bearing surfaces of the connections for seals or other connections then no longer lie in a plane that runs parallel to the main plane E of the plate heating elements, but are also inclined at corresponding angles. This makes it easier to screw the connections together when using part-cylindrical plate heating elements, and in combination

209820/0120

radiators curved with other panel heating elements being constructed.

The embodiment of the Pig. 16a shows how plate heating elements 101b in the form of quarter-circle cylinders with straight plate heating elements 61 to form an externally round one Heating column are combined. The elevations 64 are more pronounced than in the previous examples, and the connecting axles or bearing surfaces are below inclined at an angle of 90 ° to each other. In this way 'free standing heating columns can be created or supports and pillars are also encased with radiators made of plate heating elements. The pillar does not need to be completely to be closed. The elements can now be connected to one another around a corner or around two or three corners be.

The embodiment of the Pig. 16b shows a somewhat differently shaped plate heating element 101c for a radiator, which is led around an outside corner. It lies between straight areas having the connections A. a rounded corner area.

The embodiment of the Pig. 16c shows a Eckplatten- like heating element 101d for connecting the plate heaters in an inner corner. The front surface is rounded in the corner, while the rear surface in the corner is straight bevelled.

The embodiments of the Pig. 16a to 16c show how radiators according to the invention are also available in a variety of ways built in or around corners or curved can. They can also be used in a way that is not shown

./18

209820/0120

Way have any height by arranging several elements on top of each other. Inside one too Correspondingly rounded plate heating elements can be used.

The Pig. 17 shows a view of two cassette-like, lying next to one another, with different characteristics 102 and plate heating elements 61 formed as a result of differently shaped fields. Many other configurations can be used for the outer shape of the plate heating elements and the various plate heating elements shown and possibilities can be combined with each other.

FIGS. 18-45 show different assignments of the individual plate heating elements in the different levels as well as different buttons and different plate shapes.

In the embodiment of FIG. 18, as in the embodiment of FIGS. 1 and 2, square plate heating elements 61 with the same Xanten lengths b and h are used, the connections having the grid spacing r. The relationship applies here

b = »h = 2r-S

Here the edges K run parallel to the connecting lines L of the connections A, which each lie on the corner points of squares.

In this embodiment, the plate heating elements 61v of the front level E1 are arranged in three rows, the plate heating elements of each row being positioned exactly above those of the other legs. The plate heating elements 61h of the

./19 209820/0120

rear level are offset laterally and downwards by a grid dimension r to those of the front level. As a result, each rear plate heating element 61h connects with its four connection points A four different plate heating elements 61v of the front level. If it is necessary for the heating medium flow and the heating power, half elements 65 can be used at the edges, as indicated on the left. These have the width b ₂ = ^b - = ^s . .

In the Pig. 19 are the same plate d heating elements 61 as in that of the Pig. 18 is used, but the plate heating elements 61v of the middle row of the front level are offset from those of the upper and lower rows by a grid, while the square plate heating elements 61h of the rear level are exactly behind the plate heating elements of the upper and lower rows and only in height are offset by a grid dimension r. Thus, the plate heating elements 61h located at the rear connect with their four connections A three plate heating elements 6iv located at the front. Half-plate heating elements 65 are used marginally where necessary.

The embodiment of the? Ig. 20 differs "

of the previously described only in that the side edges K in the central region II offset somewhat inward so that the gap S2 is wider than in the area of the corners where the gap width is S. Furthermore here, too, the connection points A lie on the corners of squares with the grid dimension r. Here are the ones in the back Elements offset both vertically and laterally by a pitch so that they have four front plate heating elements 6Iv connect. In the same way, after

./20 209820/0120

connected on all sides. Half elements can also be used. With the same edge shape can the plate heating elements of the different levels can also be offset differently from one another.

The embodiment of Fig. 21 also shows plate heating elements, where the connections A are in the corners of a square. The grid lines 1 also have here the distance r, but the edges K only run parallel between the grid lines L of their connections the grid lines L, while the corners are broken and corner lines El at angles of 45 degrees to the grid lines L and the rest of the edges run. This results in hexagonal plate heating elements 110, but with four terminals A. The half plate heating elements 111 are pointed on the short sides.

The embodiments of the Pig. 22 and 23 show plate heating elements 130 and 131, where the connections A also again lie on the corner points of squares with the grid dimension r. Here is the outer outline of the plate heaters 130, however, is circular in shape, with the The center of gravity SM of the square is the center of the circle. However, with the same grid dimension r with the Examples of FIGS. 22 and 23 used circles of different sizes. While in the embodiment of the Pig. 22 directly adjoin one another, they overlap slightly in the embodiment of FIG. 23, so that the front plate heating elements must be arranged in slightly offset planes. The connecting plate heating elements 130h at the rear are again in the exemplary embodiment in FIG. 22 by a whole grid division r both in height and

./21 209820/0120

ι i ^:! ! ■ ■: ι: ι :! 111 ': ": ι !: ι μ: ι ■: | j: ■ ■ ;; -

- 21 -

offset to the side so that they each connect four plate heating elements 130v. Half plate heating elements can be placed on the edge 132 can be used if desired.

In the exemplary embodiment in FIG. 23, the plate heating elements 131h located at the rear are partly only in height staggered like the bottom row, while the top row the plate heating elements 131h to the front both in height and to the side by a pitch r are arranged offset.

In these two exemplary embodiments, the outer contour can also be chosen so that there are small gaps between the individual circles, making them unavoidable Tolerances do not appear. The back can be seen as Pig. 22 shows with circular Central embossings 133 provided, which also correspond well to the picture, which is also made up of circles.

While in the exemplary embodiments described above with straight edges, the distances between the edges K and the grid lines 1 or the connections A were the same in all directions, the embodiment shows the Pig. 24, like the connections A with the same square grid arrangement in relation to the surfaces of the plate heating elements are offset upwards. This enables better ventilation of the uppermost plate heating elements 115. So is ensures that heating medium also gets into the upper corners and the entire panel heating element 115 evenly be heated. The distance al to the side edges KS is the same here, too, while the distances a2 and a3 are different. The relationship applies here!

./22 209820/0120

- 22 2 al + r = a2 + a3 + r = b = h = 2r-S.

In this embodiment, the rear heating elements 115h are both to the front plate heating elements 115v offset to the side and downwards by a grid division r, so that the heating elements located at the rear Connect four front plate heating elements 115v. The half plate heating elements are also corresponding provided asymmetrically with connections A.

If you want to avoid too large water spaces above the connections A with a symmetrical arrangement to the outer edges, you can let the water space end at the level of the upper connections by welding the front and rear plates together directly above the connections or pouring them accordingly.

While in the embodiments described above, the connections of all plate heating elements in the corner points equilateral polygons in the special form of equilateral rectangles, namely the (squares, lay, are included the embodiment of the Pig. 25 used for the front plate heating elements 12Ov rectangles, the height of which h is much larger than the width b. The connections A1 and A2 as well as A3 and A4 are horizontal from each other Direction the distance r, while the connections of a front plate heating element 12Ov in the vertical have the distance 2r. This allows plate heating elements 61h located at the rear for the central connection in a square shape Shape can be used. Half heating elements 65 could be used above and below, or as in the exemplary embodiment shows, square plate heating elements 121, which have only two angles offset to one side

./23

209820/0120

Have inferences A. The plate heating elements 12Ov apply only the relationships"

h = 3r - S
b = 2r - S.

The embodiment of FIGS. 26-28 shows how square plate heating elements 125 are provided with the same edge lengths b and h, but with a connection grid system, in which the four connections A1 to A4- provided here also have the grid spacing r1 and in the horizontal direction in the vertical direction have the grid spacing r2, which are different from one another. While the same plate heating elements 125 are provided in the front and rear planes E1 and E3, connecting pieces 126 are provided in the middle of plane E2, the connections A of which are spaced r2 in the vertical direction and r3 in the horizontal direction, i.e. are very close together. Only bridging pieces 127 are provided at the ends. This results in larger chimney openings KA between the plate heating elements 125, which allow a better air flow. Like Pig. 28 illustrates, can also superiors over two levels extending heating elements 128 are _Λ see. ™

The examples explained above show the diverse possibilities of a rectangular connection grid system, even in the special shape of the square, made possible. The radiators can be turned on all sides can be continued with individual pieces or several plate heating elements, with the various types of displacement can be applied and also combined.

./24 209820/0120

The exemplary embodiment in FIG. 29 shows how a heating element is constructed from only half plate heating elements 65 which have only two connections A1 and A2. The grid dimension of this arrangement is r in both directions, the edge length h2 corresponds to half the width b / 2 minus S / 2. Here the plate heating elements 65 are the upper ones Row arranged alternately in the front and rear levels. At the right end is the rear plate heating element 65h placed vertically and connects the top row with the middle row. At the left end is also the rear plate heating element 65h again placed vertically to the middle row with the lower Connect row. At connection Al of the top left plate heating element 65v and at connection A2 of the The heating medium supply and discharge can take place with the plate heating element 65v located at the bottom right. So there is a very simple and practical structure for a radiator that allows very good variations in width and height, the entire front and rear surfaces being filled with heating elements without any flow problems gives. This arrangement is particularly suitable for rectangular radiator shapes, although made of elements with only two connections, many other shapes can be designed.

The exemplary embodiment in FIG. 30 shows plate heating elements HO in the form of angles. These each have three Connections A1, A2, a3 »those at the ends of the edges r one isosceles right triangle. As the figure illustrates, results from the rectangular Arrangement and nesting of the angular plate heating elements again an arrangement with a square Grid with the grid dimension r. In the second,

rear level are the same rear plate heating elements HOh in the form of angles with three connections A each is used. These are to the right by a grid dimension r or offset to the left and nested in the same way as at the front. Left and right is respectively yet another rear plate heater 140h is attached.

The embodiment of the Pig..31 shows rectangular plate heating elements 150, which in contrast to the previously Examples described have not four, but three rear connections A1, A2, A3. These are " arranged at the corner points of an isosceles triangle with the leg lengths d and the base r. The connection A3 lies on the center line of the rectangle, which has width b and height h. So that the elements fit together, the following relationships apply here:

b = i r - S

i ~ | f 4d ² - r ² + cS.

Here , c is the distance between two adjacent connections A of different elements.

In this case , the plate heating elements 150 are always arranged alternately, an element with an upper and two lower connections following an element with two upper connections in a row. As in the embodiment of FIGS. 26-28, three levels, E1, E2 and E3 are provided. The E1 level has just been described. In the plane E3 the same rectangular plate heating elements 150 are arranged, again always alternating,

./26 209820/0120

in a row each having a plate heating element 150 with an upper connection and two lower connections another element rotated by 180 degrees follows. They are the same plate heating elements as in level E1 is used. In the middle plane E2 are the connecting pieces 126 in the embodiment of 26-28 corresponding connecting pieces 151 with four Connections A and connecting pieces 152 with two connections A and bridging pieces 153 with only one Connection A provided.

The execution example of the Pig. 32 shows front rectangular ones Plate heating elements 160 each with three connections, which, however, in contrast to the previous example are arranged at the corner points of an equilateral triangle with edge length r. To connect the individual, Rectangular panel heaters 160 in the front plane are overlapping rear panel heaters elements 161 provided, the diamond shape and each have only two connections A, which the plate heating elements 160, as shown, connect with one another or only with the two at appropriate points Terminals of a front plate heater 160 are connected. Due to the sloping position and the diamond shape the rear surface of the radiator is almost completely filled with plate heating elements.

The embodiment of FIG. 33 shows the plate heating elements 160 of the embodiment of FIG. 32, the however, they are connected to one another with the same plate heating elements in the second level. If necessary , smaller, two-connected, rectangular ones can be used at individual points, as shown below

./27 209820/0120

Plate heating elements 163 are provided, one side of which has the width b and the other side of which has the height e. Here, too, the distance between the connections A is the dimension r of the grid.

In the examples of FIGS. 32 and 33, triangles each adjoin one another in the grid system.

In contrast, shows the embodiment of Pig. 34, like square plate heating elements 170 with three each Connections A are arranged so that connection connection points on the corner points of equilateral hexagons | while the connections are on each plate heating element the corner points of the corresponding equilateral triangles. Due to the offset position of the plate heating elements this arrangement of the connections results in the entire grid on equilateral hexagons and Triangles.

In the embodiments of the Pig. 31-34, the outer edges of the plate heating elements are not all parallel to the connecting lines L of the connection points, as it is the Illustrate figures.

The embodiment of FIG. 35 shows how in one Grid system with equilateral hexagons plate heating elements are provided, each of which has three on the end points have connections A lying equilateral triangles. Here, the plate heating elements 180 are diamond-shaped designed with sides of equal length, the edges K being parallel to the connecting lines L of the connections A run. With the same arrangement, a connection could also be made in the fourth corner of the diamond

./28 209820/0120

be provided, so that again a four-grid, but not with perpendicular lines L, but a diamond-shaped grid system would arise.

Figures 36-39 each show triangular plate heating elements 190, the connections A of which lie on the end points of equilateral triangles, the outer edges K respectively run parallel to the connecting lines L of the connections A. Only the corners are partially rounded or cut off. The figures illustrate how different distances between the edges K and the connections A and due to different relative positions to each other quite different, sometimes very relaxed, like the Fig. 38 and 39 illustrate, and in some cases very compact radiators can be created, as they are from the Figs. 36 and 37 emerge.

Fig. 40 illustrates how circular plate heating elements 200 are assembled with three connections A each, with the connections A on the corner points equilateral triangles are, however, due to the assignment of the individual plate heating elements 200 to one another A grid system is created in which the connections are each on the corner points of equilateral hexagons.

The embodiment of Fig. 41 shows plate heating elements 205 »which on the whole have the shape of equilateral hexagons, but with three connections A1, A2 and A3 are provided, which lie on the corners of equilateral triangles with edge length r. By the accordingly overlapping arrangement of the plate heating elements 205 in the front and rear plane results in whole a grid system in which the connection points in the

./29

209820/0120

- There are 29 corner points of equilateral hexagons.

The embodiment of FIG. 42 also shows hexagonal plate heating elements 207, which, however, are each provided with six connections A1 to A6. These lie on the corner points of equilateral hexagons with edge lengths r and are joined together to form an equilateral hexagonal grid in the entire grid system through the mutual offset of the front and rear plate heating elements, i

The embodiment of FIG. 43 shows that the structure of the inventive radiators with overlapping and multiply connected individual plate heating elements is not only constructed in simple geometric shapes such as square, rectangle, rhombus, triangle and hexagon, but also, for example, with a grid system can be based on the ■ equilateral pentagon. In this case, five connections A1 to A5 are provided for each plate heating element 210, which are at a distance r from one another. To form corresponding column S are set, the outer edges so that they, however, un- also form pentagons Λ regular pentagons, so that all surfaces are evenly filled. Only the two long edges 211, 212 and the short edges 213 enclosed by the long edges 211, 212 run parallel to the connecting lines L of the connections. Here, too, completely identical elements are connected to one another and result in an interesting radiator pattern.

The figures described show the variety of heater element shapes possible when using the invention is. In addition, numerous

209820/0120

other shapes by selecting the outer edges accordingly or other raster systems.

44-50 show various advantageous screw connections for the overlap and connection points A of the plate heating elements described so far, the can be used in each case according to the needs, if one does not use other connection systems, such as welding or other fittings.

The plate heating elements 61 each have a front wall 62 and a rear wall 63 »which are only in the area of the Overlap point U are shown in section and on Edge R are welded together. At the connection points A, the rear V / and plates are raised to form impressions 64. These have through bores 220.

In the embodiment of FIG. 44 are in the through hole 220 external threaded sockets 91 before welding together of the two sheets 62 and 63 are used. They each have an inner flange 221 on the edge of the hole 222 is welded in place. The connector 91a of the Drawing plate heating element 61h shown above has right-hand thread, while the connecting piece 91b of the bottom shown plate heating element 61v has left-hand thread, but is otherwise fastened in the same way. the two connecting pieces 91a and 91b are screwed together with a screw sleeve, which is also right and Has left-hand thread, so that the two plate heating elements 61v and 61h approach each other when screwed together, until the sleeve 223 presses the seals 224 firmly onto the edges 222 and thus seals properly. at this type of screw connection, which has the advantage that

./31 209820/0120

it cannot be seen from the front or back and is therefore particularly useful for free-standing radiators, however, depending on the grid system, they have to be attached to a plate heating element alternating right and left threaded connectors are provided accordingly. Instead of male thread nozzles With a screw socket that has internal threads, nozzles with internal threads can also be attached to the plate heating elements be provided, into which screw nipples provided with right and left-hand threads are screwed.

The embodiment of the Pig. 45 also has a through-hole 226 in the wall 62 of the rear plate heating element 61h, so that a screw-in nipple 227 can be screwed from behind through the plate heating element 61h into the front plate heating element 61v. As a result, the distance between the individual plate heating elements can be significantly reduced. The assembly is considerably simplified because the nipples 227 can be tightened from the outside. A nut 228 is inserted into the recess 64 in the front plate heating element 61v. This has, for example, square outer contour, which is precisely fits in the shape of the expression 64, so that they λ comparison against secured rotate. It has outwardly downwardly projecting tabs 229 'with which it is supported on the front wall plate 62 so that it is secured against rotation even when it is first applied. A seal 224 is located between the two lobes 222 of the protrusions 64. In the rear plate heating element 61h, which is to be compressed by the screw nipple 227, a spacer 230 is provided in the expression 64, which has through bores 231 that allow media to pass through. Above the edge 234 of the sheet 62 there is also a seal 224 on which the puddle 235 of the head 236 of the screw

./32

209820/0120

nippeis 227. The screw nipple head 236 can, for example have a square shape so that it can be put on very well on the one hand and on the other hand Shape of the plate heating elements fits well. The screw nipple 227 has a central recess 237 and several transverse bores 238, which, in conjunction with the annular groove 239 of the spacer 230, allow water to pass through properly. The screw nipple 227 ends at a distance from the front wall 62 of the front plate heating element 61ν, see above that water can also pass through here. This screw connection can be made particularly flat and This enables radiator thicknesses of only about 35 40 mm, as was previously the case with four heating surfaces over almost the entire radiator surface was not possible.

The embodiment of the Pig. 46 corresponds in most parts to that of Pig. 45. Only that is Head equipped with a countersunk inner square 242. Otherwise, the same parts are given the same reference numerals Mistake.

The embodiment of the Pig. 47 shows a representation corresponding to FIGS. 45 and 46, but with longer screw nipple 245, which enables three plate heating elements 61v, 61m and 61h to be connected to a common To hold screw connection tightly together, the water passage through lateral recesses 238 in the walls 246 of the nipple shaft is guaranteed. Otherwise, the same elements are provided with the same reference numerals. If even more plate heating elements are screwed one behind the other, longer, similar Screw nipples can be used.

./33 209820/0120

In the above-described embodiments of the Fig. 45 - 47 slightly different plate heating elements are required for the construction of the radiators, because the middle and rear plate heating elements have through-holes for inserting the screw connections need while the front panels are smooth. This requires the storage of various Plate heating elements, but offers the advantage of smooth visible surfaces. The manufacturing effort is not considerable larger, since a punching tool which punches the holes in the rear plates 63 is required anyway f is. The recesses 226 of the front plates 62 can also be punched in this.

The embodiments of the Pig. 48-50 differ with an otherwise similar structure mainly in that both outer plate heating elements have openings 226 in the outer walls and connections with screw and external nut are selected. Thus, completely identical parts can be used for the outer plate heating elements . It is provided that the cover plates 62 having the two heating elements in the region of the connecting points A parallel to the forms 64 of the back wall plates 63 lie U constricting, conical necked hole edges 250 in which the countersunk heads 251 and Senkmuttern are 252 of the screw connection. Under These heads or nuts are also provided with seals 224 as well as between the plate heating elements 61v, 61h and possibly 61m, with spacers 230 with through bores 231 for the heating medium being provided in all of the plate heating elements.

The embodiment of Fig. 48 shows a screw 255, which has a central full shaft 256,

./34

209820/0120

which, however, is much smaller in diameter than the through-bore 226, so that water can pass between the bore wall and the shaft 256. Nut 252 and screw head 251 are each provided with inner square edges 242 for tightening. The shaft has external threads 258 while the nut 252 has internal threads 259.

The embodiment of Fig. 49 differs from that of the Pig. 48 only in that an intermediate heating element 61m is inserted. This is two of the same Plates 63 constructed as they are for the front and rear plate heaters 61v and 61h on the rear 63 are related. The deep impressions 64 result in a greater spacing and thus larger 'chimneys KA between the individual plate heating elements 61. In the expression 64 is a correspondingly long intermediate piece 230a with through holes 231 are used. Corresponding the shaft 256a of the screw bolt 255a is also made longer. Otherwise the structure is the same as in the embodiment described above. Here, too, are only completely for the two outer plate heating elements same parts used. Only two different types of wall plates are required for the heating elements, from which outer and middle plate heating elements are built.

The execution example of the Pig. 50 is different from the one after Pig. 48 only in that no full tenon is used in the screw 260, but that this one as in the embodiments of the Pig. 45 - 47 is executed in the middle with a channel 237, which lateral Openings 238 for the medium to pass through

./35 209820/0120

shows. Otherwise, the same parts are provided with the same reference numerals and the structure of the plate heating elements corresponds completely to that of the embodiment according to Pig. 48. Instead of countersunk nuts you can cutters lying on the outside can also be used, so that configurations corresponding to Figs. 4-5 - 47 but with passage locks.

Bas embodiment of the l ^? ig. 51 shows two plate heaters 27Ov and 270h may at their overlap point, you are the previously described ä surrounded very similar in shape. In contrast to the previously described plate heating elements welded together from pressed sheet metal parts, however, they are made in one piece from cast, for example from gray cast iron or preferably from cast aluminum. As a result, the water space can be reduced in size, and wide, protruding edges R result next to the embossments 64 at the connection points A and thereby a better ventilation.

The screw connection corresponds to the Pig embodiment. 45, where the same parts have the same reference numerals are provided.

The V, ^T and thickness of the cast part is thicker. This eliminates the need to insert nuts, and an internal thread can be cut into the bore 271 of the front plate heating element 27Ov, into which the plug 227 is screwed. Due to the greater stability and structural rigidity of cast bodies, spacers can be dispensed with, although transverse webs can also be provided in the area of the embossments 64 for reinforcement and for the proper absorption of the compressive forces during strong tightening. Front

./36 209820/0 1 20

and rear plate heating element differ only in that the rear plate element 270h also has a through hole 226 in its outer wall and that in its form 64 no threaded hole is provided, but a sufficiently large through hole.

Instead of the screw connections shown, you can also other commercially available screw connections or separately manufactured screws, nipples and sleeves can be used. Right-hand and left-hand threads are required for the socket connection and the nipple connection. Pure One element type is sufficient for a grid with an even η. Pur grid with odd η two types of element are necessary, because a grid point must have a left-hand thread at one point and a pike thread at another time. They can also be conical Form approaches in the smooth heating elements, which are plugged into one another and with corresponding holding bodies are pressed together in a liquid-tight manner. The "Wt & zelnen Screw connections can optionally be attached to the numerous previously Plate heating elements described with different grid systems and different exterior designs are used will.

Construction forms of the radiators, profile forms of the plate heating elements, For the sake of clarity, grid systems and types of screw connections have each been given different ones Possible variations are shown separately from the other features of the Plattenheizeler.ente or radiator. They can all be sensibly combined with one another and used on parts with the other characteristics.

The plate heating elements can be multiple at the front design varied, e.g. paint,
