The invention relates to heating systems, namely to the Central heating systems of buildings, working on hot water, water vapour and other fluids.

Known sectional cast-iron heating device with tubular elements of the heat carrier, finned and holes for connection between them. (See AS the USSR # 214060, CL F28F 3/12, 1968)

The disadvantage of this design is the large metal consumption per unit of heat-emission surface of the device, the complexity of the installation, it requires precise machining machining for the formation of the internal threaded connection of the sections.

The closest in technical essence and the achieved effect and is selected as the closest analogue is the heating device containing interconnected sections of two finned tubular elements each connected to the heating system. When this tubular elements in each section and interconnected by means of adapters, each of which is made in the form of a hollow housing with the screw holes. (See RF patent №2042891, Appl. 1991.11.20, publ. 1995.08.27, CL F24 9/14, F28F 9/26 "Heater").

However, the known technical solution on the one hand contains elements made of grey cast iron by casting, which requires considerable costs ex what is high intensity, on the other hand it contains two channels for the movement of the fluid in which the velocity of the fluid at the entrance and inside the same, which entails reducing the heat transfer fluid.

The present invention is to increase the heat transfer fluid, reducing the cost of manufacture, simplifying the build process.

The technical result that allows to solve the problem is to optimize the design of finned members, which are manufactured by stamping plates, one of the planes which made at least three stepped ledges in the form of nozzles, a wide portion which is adjacent to the plate, and the coolant channels are formed is inserted into each other nozzles adjacent fin elements.

This object is achieved in that in the known heating device in the form of a section with the coolant channels formed by finned elements according to the invention, each of the fin elements is a plate, one of the planes which made at least three stepped ledges in the form of nozzles, a wide portion which is adjacent to the plate, and the coolant channels are formed is inserted into each other nozzles adjacent fin elements.

We offer heating device can be manufactured in any enterprise, specializing in the industry, since it requires the known materials and standard equipment, widely produced by domestic and foreign industry.

Thus, the inventive heating device meets the criterion of "industrial applicability".

We offer a set of essential features reports claimed heating device new properties that allow you to solve the problem, namely, the increase of heat transfer, reducing the cost of manufacture, simplifying the build process.

The implementation of fin elements in the form of plates, one of the planes which made at least three stepped ledges in the form of nozzles, a wide portion which is adjacent to the plate, allows you to quickly and easily assemble the sections of the heating device, and enables automation of the entire process of manufacture of stamped parts. In addition, this form of finned elements increases the heat exchange surface and increases the heat transfer fluid. The presence of pipes stepped form allows the build process section immediately receive channels for the movement of the carrier without the use of additional tubular elements, which also reduces the intensity and simplify the manufacturing process.

The presence of caps, one of which is connected with the first, and the other with the last finned element section with the formation of the mixing chambers, increases the path of flow, and thus increases the heat transfer fluid.

Setting input pipe input cap with a gap of 0.9-1.3 mm, relative to the beginning of the entry channel of the heat carrier allows you to create a turbulent movement of the fluid in the inlet mixing chamber, which leads to the purification chamber from contamination and improves the conditions of the heating device.

Thus, the scoop is Prosti essential features of the proposed heater allows you to solve the problem, to increase the heat transfer fluid, to reduce manufacturing costs, simplify the build process.
