Hot water heating element

The invention relates to a hot water Eolirheizkorper, consisting from an upper and lower manifold and between the two arranged connection pipes, the radiator with a, Strand preferably junction-like cladding with slits is.

Such radiators are known per se. You can do them in different ways Manufacture large units and assemble them in a modular manner The main drawback of such a compound or greater built radiator units is that the. Heating | performance of the entire radiator varies along its length is. The connection pipes on the hot water inlet are relatively hot, while the connecting pipes at the end have practically no longer a permanent water run; received and with it are significantly weaker in their heating power than the connecting pipes assigned to the inlet.

The invention is based on the object of addressing these shortcomings remove. It consists in having a number of radiators

. Can be assembled in a modular manner and the radiators are different Have cross-sections of the connection tube, such / that · the radiator closest to the hot water inlet the smallest cross-sections and the radiator at the end has the largest connection cross-sections. This has the essential advantage that the Yfarm water inlet assigned, So radiator units lying at the entrance have a smaller one Have hot water throughflow than the heating P at the end body units, so that there is an even effect along the entire length of the interconnected radiators results. Of course, this idea of the invention is not only applicable to modular radiators, but also with radiators, which are the same on a relatively large width are built. However, this concept of the invention is particularly advantageous in the case of radiators that are assembled in the manner of a modular system.

Another essential idea of the invention is to provide the connecting pipes with constrictions of different strengths. The number of constrictions can also be varied « This gives the opportunity to use the late ^ Direct arrangement of the radiators initially do not take any consideration must, but all radiators equally with the same size To provide collecting and connecting pipes, while then by an additional operation without technical difficulties Constrictions of the connecting pipes can be attached. In order to achieve the mentioned effect, it is necessary to give the warm

forms, without any constriction.

The essential advantage of the above measures is that the effect is achieved with simple and relatively inexpensive means that a uniform heating is possible over the entire length of the assembled heater unit * The connecting pipes provided with rigid g stronger constrictions give practically a smaller water flow and practically form a brake in the circulation system, so that the hot water is forced to flow into the pipes at the end of the radiator unit in order to give off heat calories here as well.

Otherwise it does not matter how the radiator is made is whether now heat exchange plates with louvre-like slots Find use or whether the pipes in a sheet metal cladding lie ,, which serves as an air shaft and in the lower part | Inlet openings are present for the fresh air, which is called warm air is dispensed in the upper 'lid part. It is essential that extremely long radiators or modular heating elements ■ bodies are brought to a heating unit through the cross-sectional constrictions of their connecting pipes, which has a has at least approximately the same heating power. This problem is especially important when the heater is set to the lowest level, so The radiators, which are of different sizes in the individual rooms, are fully effective in this dimension

As can be seen from ELgur 1, such a heater is assembled in a modular manner to form a heating unit. The single ones Radiators are stranded with the reference numerals 11 to 14. Her Side walls are close together and are preferably screwed together, while the headers 1 and 2 are connected to one another by screw sockets or push-in sockets.

This entire radiator unit should now have a uniform effect over the entire width. The heat-carrying medium is now admitted into the lower collecting pipe 2 in the arrow direction 0. Of course, there is also the possibility of _admitting the heat-carrying medium into the upper collecting pipe 1. In this case, it depends on whether a more powerful pump is available to ensure the circulation. Less power is required. when the heat-carrying medium, for example hot water, is let into the manifold 2. From the lower collecting line 2, the hot water now ascends into the connecting pipes J. According to the invention, these have different cross-sections, the connecting pipes 5, which are closest to the hot water inlet, have the smallest cross-sections, while the radiators at the end, in the embodiment of the figure 1 numbered 14, which have the largest connection cross-sections. The cross-section change can be produced in various ways. In the exemplary embodiment shown in FIGS. 1 to 5, constrictions are provided which, on the one hand, can be selected to be stronger or weaker and, on the other hand, are different in number * decisive

Furthermore "there is the possibility with very" wide tubular heaters, the manifolds 1 and 2 at the transition from a radiator in the other with a closure, so that the hot water is forced through the radiator again and again to cross the connecting pipes.
