Description

The invention relates to a multi-row radiator with a partial load function with a variable connection to the heating system network. This is preferably a flat radiator or a heating wall with vertical or horizontal arrangement of heating pipes or channels according to the restrictive part of paragraph 1 of the claims.

Similar radiators with devices for directional wiring of the coolant to achieve the partial load function are already known. Thus, it should be achieved that during the heating process, the coolant passes, preferably, through the heater section or the heating plate directed towards the heated room and, thus, a quickly noticeable heating of the room occurs.

Radiators of the mentioned type are described, for example, in publications EP 1227290 B1, DE 3216922 C2, DE 202004019163 U1, DE 202004017628 U1 and DE-PS 25117611.

Radiators, which at partial load have improved performance towards the room (higher surface temperature of the front plate and, therefore, more radiation into the room), can be implemented in various ways. One of the possibilities is the sequential inclusion of individual heating plates in such a way that the coolant first passes through the plate facing the room, and then through the plate (s) facing the room.

Constructive forms of a radiator based on this principle will be of great importance in future repair and modernization activities, as a result of which special attention should be paid to options without a built-in valve and at the same time a completely freely selectable arrangement of plug-in connections (VL (feed) from top left or right with RL (drain ) bottom left or right).

DE 202005012826 U1 describes fittings for incorporation into radiators, which themselves extend longitudinally with respect to the radiator and provide the necessary connection diagram. In this case, the fittings depend on the structural length of the radiator, as a result of which suitable sets must be provided for each structural length.

In EP 1227290 B1, in one structural form, in one of the transverse channels, an insertion part is located in the feed stroke region, while by means of the insertion part, the supply water can be directed to another transverse channel. In another structural form, in one of the transverse channels, the insert is located in the region of the connecting part, while the heat transfer from the transverse channel to the connecting part is prevented by the insert. Other publications describe similar solutions with a variety of plug-in details. The disadvantage of such solutions, first of all, is that in front of the valve nipples and locking threaded connections, corresponding plug-in parts must be installed in the connecting tees according to the installation manual.

Therefore, the task underlying the present invention is to develop a universally connected radiator that is operable with a partial load function and can be implemented regardless of the structural length and / or structural height of the radiator and, therefore, can be made more simply and economically. Also, due to this, connection errors that can have a negative effect on the partial load functions should be excluded.

This task according to the invention is solved by the features of paragraph 1 of the claims. Preferred improvements of the invention are contained in the dependent claims.

According to this object of the invention, there is a radiator, in particular a multi-row flat radiator or a heating wall with vertical or horizontal arrangement of heating pipes or channels, consisting of at least two heating plates and supply and drain pipes for connecting to the heating system network, while first passing the coolant of the heating plate facing the heated room, and then the heating plate (s) located behind it (s), and between Connecting fittings are provided on each upper lateral end portion and each lower lateral end portion by connecting plates. According to the invention, the connecting fittings located on the upper lateral end portions communicate exclusively with the front heating plate, and the connecting fittings located on the lower lateral end portions communicate exclusively with the rear heating plate (s), with the center between additional connecting fittings are located on the heating plates, which in the center directs the heat carrier from the front heating plate to the rear heating plate (s) (- s).

Particularly preferably, it is provided that the central connecting fixture is in the form of a vertical ascending pipe (pipe for raising water), which in the center directs the coolant from the lower level of the front heating plate to the upper level of the rear heating plate (s) (s) ) According to another preferred embodiment of the invention, it is provided that the central connecting fixture is made in the form of a horizontal connecting pipe, which in the center connects the lower levels of the heating plates. Preferably, this connecting pipe in the lower level region of the rear heating plate has a guide device that causes the coolant to rise to the upper level of the rear heating plate (s) (s).

The technical result achieved in the invention is to ensure the versatility of connecting a radiator operated with a partial load function, while reducing the range of fittings, as well as ensuring ease of installation of the radiator regardless of its structural length and / or height. In particular, connecting the central heating plate located behind the heating plate to the center of the front heating plate simplifies the assembly of the radiator, reduces the range of fittings and, consequently, production and logistics costs, while ensuring uniform heat transfer along the length of the radiator. Thanks to this, such a radiator can be manufactured more simply and economically. In addition, due to this, connection errors that can damage the partial load functions can be eliminated.

The radiator according to the invention comprises two or more heating plates arranged one after another. These plates in one embodiment are provided at the upper corners with connecting elements that communicate exclusively with the front heating plates, and at the same time at the lower corners have connecting elements that communicate exclusively with the rear heating plate (s). In the center of the radiator is a connecting fixture that directs the coolant from the lower level of the front plate to the upper level of the back plate (s). In a particularly favorable embodiment, there is communication between the front plate and the rear plate (s) from the connecting tube in the lower region. In short radiators, the coolant entering the back plate (s) is rationally directed upward by means of an insert element, in long radiators this measure may not be present, since there is less danger of improper circulation.

In the radiator according to the invention, the heating plates may be formed of profiled plates with vertical flow channels and horizontal manifolds or may consist of flat pipes that are connected to each other by means of manifolds.

Further, the invention is explained in more detail, with the disclosure of its further advantages, using the figures shown in the drawings, which show:

Figure 3 shows a two-row flat radiator with a supply pipe and a drain pipe and a first flow-through and facing, preferably to the heated room, heating plate 1.1 and the next flow-through and located preferably behind the heating plate 1.n and connecting on each upper end section fittings a, b and connecting fittings c, d located at the lower end sections. Shown in figures 1-3 radiators are cut in the upper region horizontally. The heat carrier stroke indicated in figures 1 and 2 by arrows shows two different types of connection. In Fig. 1, the discharge and return flow are connected on one side through the connecting parts a and c, while in Fig. 2, the supply line is connected through the connecting part b, and the drain is connected through the connecting part c.

In the center between the heating plates 1.1, 1.n, there is another connecting fixture e, which in the center directs the coolant from the front heating plate 1.1 to the rear heating plate 1.p. According to figures 1-4, it is provided that the central connecting fixture e is made in the form of a vertical ascending pipe (e ') (pipe for lifting water), which directs the coolant in the center from the lower level 1.1.2 of the front heating plate 1.1 to the upper level 1. n.1 back heating plate 1.n. According to another embodiment shown in FIGS. 5 and 6, the central connecting fixture e is made in the form of a connecting pipe e ″, which in the center connects the lower levels 1.1.2 and 1.n.2 of the heating plates 1.1, 1.n. Preferably, this connecting pipe e ″ in the region of the lower level 1.n.2 of the rear heating plate 1.n is equipped with a guide device that causes the coolant to rise to the upper level 1.n.1 of the rear heating plate 1.n.

Since the invention in its embodiments is not limited to flat radiators only, FIGS. 7-12 show horizontal and vertical heating walls (horizontal and vertical heating walls with features of the invention). 11 and 12 show heating walls with a connecting pipe e ″, while FIGS. 7-10 show heating walls with an upward pipe e '. In order to avoid repetitions, a repeated description is not given in this case.

In particular, FIGS. 9-12 show a radiator according to the invention with heating plates 1.1 and 1.n consisting of flat pipes that are connected to each other by means of manifolds. Figures 1-6 show a radiator according to the invention with heating plates formed of profiled plates with vertical flow channels and horizontal collectors.

The principle of operation of the radiator proposed in the invention in all its variants involves the passage of the coolant first through the front heating plate facing the inside of the heated room, and then through one or more heating plates located behind it. Since the radiator according to the invention has no moving parts, its operation is clearly illustrated in FIGS. 1-2 and 6-12, where the arrows show the direction of movement of the coolant.
