DESCRIPTION OF A USEFUL MODEL

Radiator heating steel panel double non-clogging

This utility model relates to the engineering equipment of buildings and structures and is intended for heating residential and industrial premises.

Known heating radiators are steel stamped panel type RSV 1. A disadvantage of radiators of the known type is as follows. The radiator channels are in unequal hydraulic conditions: the pressure difference between the inlet and outlet for the channels located on the part of the radiator remote from the riser is much less than the pressure difference between the inlet and outlet for the channels closer to the riser. Therefore, in channels remote from the riser, the water velocity is much lower than in channels located closer to the riser. This leads to the formation of stagnant zones and the deposition of dirt in the channels remote from the riser, and these channels are relatively quickly clogged with rust and other foreign inclusions present in the water flowing through the radiator. As a result, the surface of the radiator heats up unevenly, with strong blockages, some part of it may not warm up at all, which leads to a significant deterioration in the heat transfer of the radiator. In order for the water velocity to be the same in all channels, the following method of connecting a radiator is known: water is introduced into the upper left corner of the radiator, and the output is from the lower right corner of radiator 1. With this method, the connection of stagnant zones and blockages does not occur, and the entire surface of the radiator heats up evenly. The disadvantage of this connection method is that it is almost impossible to implement in residential buildings: this would require the installation of an additional pipe under the radiator.

The technical result that can be achieved due to the proposed utility model consists in the complete elimination of stagnant zones and blockages and uniform heating of the entire surface of the radiator, which will lead to an increase in its heat transfer, while maintaining the shape of the radiator familiar to the population and without laying additional pipes. At the same time, the product is made from already known parts and elements, which will allow it to be produced at extremely low additional cost.

UDC 697.

the carrier is fed into the upper left corner of the panel 1 through the curved pipe 4. The curved pipe 4 is connected to the panel 1 by welding or threaded connection. The coolant is removed from panel 1 through corner 5, welded to panel 1 in the lower right corner. Next, the coolant passes through the transfer pipe 6, corner 7 and enters the upper right corner of the panel 2. From the panel 2, the coolant exits through a straight pipe 10 located in the lower left corner of the panel 2. A straight pipe 10 is connected to the panel 2 by welding or threaded connection.

For the manufacture of pipes 4 and 10 and the transfer pipe 6, pipes are used having a diameter equal to the diameter of the riser. The inner diameter of the corners 5 and 7 is larger than the outer diameter of the transfer pipe 6 by 0.2-Yu, 5 mm. The length of the transfer pipe 6 is selected so that it enters the corners 5 and 7 per cm.

In the manufacture of the product, the transfer pipe 6 is inserted into the corners 5 and 7, and the corners are welded by welding 8 to the lower right corner of the panel 1 and the upper right corner of the panel 2. After that, the corners 5 and 7 are welded by welding 9 to the transfer pipe 6. This assembly method allows to minimize the error between the holes in the lower right corner of the panel 1 and the upper right corner of the panel 2. If the manufacturer's conditions allow to maintain the necessary manufacturing accuracy, then the transfer pipe 6 and corners 5 and 7 can be replaced by internal tube bent from both sides. In this case, the appearance of the product will improve, and there will be no welds 9.

The radiator is attached to the wall using the ear 11. Each panel has four ears.

To connect the radiator to the branches from the riser, a standard pipe thread 12 is cut at the end of pipes 4 and 10.

In the radiator of the proposed design, the velocity of the coolant in all channels will be the same, so the possibility of the formation of stagnant zones and blockages is excluded. The coolant can move along the radiator in any direction, that is, enter the pipe 4 and exit the pipe 10 or enter the pipe 10 and exit the pipe 4. The performance of the radiator does not depend on the direction of movement of the coolant in it.
