The technical field to which the invention relates.The invention relates to a modular bimetallic heating radiators designed for domestic heating systems. Heating assests the modules.Art
Compared with existing pipeline systems that use steel fully integrated, bi-metal module, which is the subject of the invention, provides the circulation of the heating fluid in a closed path, and a significant reduction of production costs. Currently, modern production in this area is bimetallic modular radiators, which can be quickly assembled on site. These radiators consist of embedded steel structures, within which circulates the heating fluid medium and which is placed inside the enclosure made of aluminum alloys and having a system of fins to increase the heat exchange surface. Such radiators is selected as the closest analogue, bimetal radiator, disclosed in the publication of the application for the grant of the European patent EP 0481154 A1. These radiators are manufactured on automatic production lines, have good thermal efficiency, and from them you can collect items required configuration, fit well with the interior; however, the use of all steel piping system significantly increases rasih, prior is characterized by a system of steel pipes inside the external casing of the module is made of aluminum alloy, to prevent the formation of hydrogen as a result of corrosion of the walls of the aluminum alloys of turbulent flows that occur in the piping and the occurrence of defects in heating systems. To prevent these defects, it is necessary to provide the heating module exhaust fitting for periodic release of gas. While thermal efficiency is always determined by surface pipelines, the use of steel pipelines is caused primarily by the need of the heating device in a closed loop. The above solution significantly increases the cost of production, since in accordance with the technology of the prior art for the production of steel pipelines should: a) a certain number of blanks pipelines; b) the Assembly of these blanks using seam welding on the production line to receive designs; C) equipment for installation and fixing of these modules in multiple form for casting under pressure; g) installation design production elements.The invention
The present invention is the creation of a piping system for heating the fluid in the modular bimetal radiators, which, along with the advantages of bimetallic heating radiators, containing all steel built-in items (in particular, the prevention of pipeline corrosion of aluminum alloy), do not have inherent disadvantages listed above.It should be borne in mind that aluminum is an amphoteric metal, because it can affect and acid and alkali, and although there is a very high affinity of aluminum to oxygen, causing aluminothermic reaction, aluminum is the most electrophoretically of all metals and is not subject to corrosion from exposure to air or water in the absence of turbulence. When it is used in the pipeline with water, as in this case, it provides uniform distribution of heat through the circulation of the heating fluid inside straight piping system with closed circuit. This is due to the fact that the occurrence of even a very thin layer of aluminum oxide, which is stored in premoli the IKI. However, if the movement of the liquid in the pipeline becomes a vortex character, which leads to mechanical removal of the inert layer, the corrosion of the wall due to erosion. If we consider the flow moving inside the heating device with the closed contour consisting of one or two modules with the piping system formed by a pair of parallel straight pipes horizontally and fastened in the middle of the straight vertical pipe, you can see the breakdown flow only in connection with the internal holes of the module, namely, in connection with one or more vertical pipes, in which there is a sharp change of direction a certain quantity of water. Disruption of the flow that occurs in the connecting sleeves of the modules has a small or negligible value. As water enters the pipe of smaller diameter, in the process of operation of the heating system is a slow erosion in the areas of the holes of the horizontal pipe, which reduces the inert layer of aluminum alloy.The above reasoning leads to the conclusion that in order to prevent corrosion of the pipeline the different parts of the pipeline. Therefore, the components of heating systems are greatly simplified, as new technologies allow manufacturing modules housings, cast aluminum alloys, for installations space heating system piping fluid made in accordance with three main options: a) one or more vertical pipes are made of steel, and the rest are formed in an aluminum casing; B) the neckline of one or more vertical pipes are made of steel and other pipes are formed in an aluminum casing; C) a pair of horizontal piping is made of steel, and one or more other vertical pipes are formed in an aluminum casing.According to one of the mentioned variant of the invention proposes a system of pipelines for heating the fluid in the modular bimetallic radiators having a vertical portion and a horizontal portion formed by two parallel pipelines, and contains formed in a mold modular case, which can be made of aluminum alloy and at least one built-in steel pipe. Built-in steel truboprofilnogo fluid medium and having an end portion, located associated with two parallel pipelines horizontal part of the module, and parallel pipelines are made in the same mold, and the end part of the steel pipe are of the form that corresponds to the wall parallel pipelines to prevent corrosion of pipelines from aluminum alloy, leading to internal parts, and the suppression of the action of turbulence on the neckline.In another embodiment, a piping system for heating the fluid in the modular bimetallic radiators has a horizontal pipelines, and at least one vertical pipe, the ends of which are included in the corresponding holes in horizontal pipelines, and contains modular aluminum alloy. Mentioned pipelines are made directly inside the module housing, and contain steel built-in items necks with a Central through hole and surface in the shape of the surface of the horizontal pipe, and the above-mentioned steel elements necks are protective against corrosion of the wall caused by disruption of the thread that has the heating fluid in the modular bimetallic radiators contains aluminum alloy with integrated dual horizontal steel piping, arranged parallel to each other and having openings aligned with the openings of at least one vertical pipe, and mentioned vertical line made directly into the body.List of figures
