Definitions

• the invention relates to a modular radiator made of parallel thin-walled profile slats connected by pipes of the heating medium, in particular of aluminum and its alloys.
• the main task of radiators is to ensure the greatest possible heat transfer from the heating medium that flows into hot water pipes in a heated room. Since the amount of heat transferred depends on the size of the heat exchange surface, the heat of the heating medium, which flows into hot water pipes in a heated room, is transferred from the hot water pipes via fins and other heat exchange elements with a large heat exchange area. These fins and other heat exchange elements have a wide variety of shapes and designs, are arranged on the heat water pipes and are either arranged transversely to the heat water pipes or the heat water pipes are inserted longitudinally into them. The heat transfer is also dependent on the temperature difference between the heating medium flowing through the hot water pipes and the immediate vicinity of the radiator. It is therefore necessary to keep this temperature difference as large as possible at all times.
• radiators which have cavities which are formed from sheet metal by pressing. In particular, vertically arranged cavities contribute to a faster circulation of the ambient air.
• different additional profile heat exchange surfaces which are formed from corrugated sheet metal and are attached to the surfaces of the hot water pipes, are inserted into the radiator.
• the additional profile heat exchange surfaces are welded longitudinally or transversely to the surfaces of the hot water pipes of the radiator or are placed in the spaces between them. Countless designs of this type are known, but their common feature is complicated construction, little variability in shape, impossibility of assembly on site and complicated assembly. In the case of double-panel radiators, additional profile heat exchange surfaces can be formed by vertical bevels with a mutual offset. However, this is a very complicated construction and also does not allow variable assembly at the place of assembly. The choice of location and size of the additional heat exchange surfaces is restricted by further functional elements of the radiator, in particular by end grommets, top grids and holders. The arrangement and size of these elements significantly complicate the construction of the heat bodies.
• radiators On the bottom edge of the radiator with bottom or Central connection, with distribution of at least one branch of the heat transfer medium by means of different pipe systems, it is difficult to achieve the appropriate distances from the top and bottom edge of the additional heat exchange surface.
• a common disadvantage of known radiators is the complexity of their shapes, the high number of mounting elements, the complicated manufacture and the complicated adaptability of the shape of the radiator to the requirements that result from the aesthetic and technical design of the interior.
• the radiators are mostly made of anticorrosive surface-treated steel, aluminum ' - and its alloys.
• the connection of the individual heat exchange elements of the radiators and their strength also form a source of problems. From the file DE 4323488, for example, a mounting element for quick clamping of wooden workpieces is known, which can be used in the field of radiator technology.
• the assembly element is formed by a central element, which is formed by a cavity which is created on the inside by four diagonally placed tubes in a square shape. There are two profile grooves on each side for the clamping element with screw.
• the assembly elements mentioned are constructed from the point of view of a high cross-sectional stress as a thick-walled tubular shape with a central element. By assembling the elements, a radiator with hot water pipes and a relatively large heat exchange surface can be formed.
• a disadvantage of the thick-walled mounting elements with a central element of circular tubular shape is that they are unnecessarily heavy and do not form any cavities in cross section, which are advantageous for a modular assembly in the radiators and as a result, do not create conditions for more intense heat transfer in air flow.
• a modular heating element is known from the document EP 0183211, which is formed from thin-walled slats into which a horizontally arranged hot water pipe is inserted. The thin-walled lamellas are made in one piece with the hot water pipe and from this pipe they run upwards, downwards and sideways.
• the walls of a sideways running thin-walled lamella are provided with ventilation holes and shaped for a complete flow around the air.
• a particular disadvantage is the low variability in the shape of the radiator.
• a heat exchanger is known which is formed by a hot water pipe for the heating medium, from the walls of which thin-walled surface elements - ribs of identical shape run, which are intended for heat transfer from the hot water pipe to the environment.
• the thin-walled surface elements are closed at their free ends by blocking elements with a V-shape. After these elements have been hooked into one another, the locking elements are firmly connected with a spring.
• the hot water pipe is inserted into the thin-walled surface element parallel to the locking elements and is created.
• a disadvantage of this arrangement is the need to form a closed shape of the exchanger and the location of the hot water pipe, which does not allow a free modular assembly and a variety of shapes of the radiator.
• the aim of the invention is to eliminate the disadvantages of the prior art and to ensure a simple modular radiator which consists of a minimal number of construction elements which are not demanding in terms of manufacture, which allow the emergence of a wide range of modifications and the required aesthetic execution of the interior easily be adaptable, have small dimensions, low weight, simple construction and high heat output, are self-contained, easy to maintain, will be easy to manufacture, assemble and disassemble.
