Description

Heating devices for central heating systems in the form of concrete panels are known, while the metal core of the thin-walled pipe is laid in a wavy concrete shell.

The proposed heating device is one of many variants of concrete panels, but in comparison with the known ones it has increased hydraulic resistance and heat transfer. This is achieved by increasing the rate of movement of the heat transfer fluid over the coil core. The coil core is made of pipes of small diameter (8-10 mm) and has a wavy shape in plan.

FIG. 1 shows one of the variants of the proposed heating device, front view; in fig. 2, top view; in fig. 3 - core-coil, front view; in fig. 4 - the same, top view.

The device consists of a core (zigzag coil) / made for water heating systems from thin-walled electric-welded pipes of small diameters D 8 × 1 mm and LGM according to GOST 1753-53. For steam heating systems, also electric-welded pipes D 9x1.5 mm and D 11ХК5 lsh manufactured from cold-rolled strip should be used.

At the ends of the core tubes, two flanges 2, 60X30X5 mm in size, are welded to connect with the connections of the system. The distance between the centers of the flanges is 500 mm.

For rigidity of the coil, clamps 3 of round steel (ejection) with a diameter of 4 mm are welded to it.

The core is taken in a wavy concrete holder 4 with a thickness of 30 mm for the fins. The shape of the cage is made with regard to the core zagzag and the possibility of installing the device on the walls with niches and without niches for direct connection with liners without ducks. Concrete is accepted brands 150 - 200. Concreting of the device is done in cassettes.

The heater is installed on the walls at a distance of 25 mm from its front surface, as a rule, under window openings with yqeTQjM, providing them with two-way heat transfer. The device is fastened to the wall on special forged brackets of 3 mm iron by means of four bolts with nuts fixed in metal strips 5, welded to the coil and embedded in concrete.

The proposed heater may be used in individual cases, depending on local conditions and in the presence of small diameter pipes.

Subject invention

A heating device for central heating systems in the form of a metal core-coil of thin-walled pipes embedded in a concrete corrugated shell, characterized in that, in order to increase flow resistance and heat transfer of the device by increasing the speed of the coolant through the core, (8-10 mlg n has a wavy shape in terms of.
