Description

 The invention relates to heating equipment, namely to central heating systems of buildings operating on hot water, water vapor and other coolants.

 Known heater skirting type, including horizontal pipes connected by a vertical plate, perpendicular to which are the elements of the fins / 1 /.

The disadvantage of this design is the low nominal density of the heat flux (less than 700 W / m ² ) and bulkiness.

 Closest to the claimed heating device is a cast-iron heating sectional device with tubular elements for the coolant, fins and holes for interconnecting / 2 /.

The disadvantages of the prototype are the low heat flux density (less than 700 W / m ² ), a large metal consumption per unit of the heat-transfer surface of the device, the difficulty in installation, it requires accurate machining for the formation of internal nipple joints of the sections between each other. Such heating devices have not found application in heating buildings.

 The aim of the invention is the creation of a heating device with a high heat flux density while reducing material consumption, reducing the complexity and cost of their manufacture.

 The technical result consists in increasing the convective and radial components of the total heat transfer due to the irregular heat transfer regime repeated in each tubular element.

 This technical result is achieved in that in a heating device for central heating systems, consisting of sections with tubular elements for a coolant, fins and holes for interconnection, the sections are equipped with internal radial and external contours of the fins with bilateral upper, lower and longitudinal holes, moreover at the junction of the sections, gasket-rippers of the coolant flow are installed, and the tubular elements of the extreme sections are connected by a pipe.

 This design ensures the creation of a continuously repeating effect of irregularity of the heat transfer regime in the tubular elements and allows for lower material and labor costs to obtain a higher heat flux density.

 In FIG. 1 shows the proposed heating device, General view; in FIG. 2 same, top view; in FIG. 3, section AA in FIG. one.

 The heating device for central heating systems consists of separate sections 1 with upper and lower tubular elements 2 for coolant circulation, interconnected by internal radial and external fins 3, 4, with upper and lower central holes 5 made, upper and lower side and longitudinal holes 6,7, designed for the movement of air and the connection of sections 1 to each other.

 Between sections 1 at the points of their connection by tightening bolts with pins 8, ripper gaskets 9 are installed. The upper and lower tubular elements 2 of the last section 1 are connected by a pipe 10. To connect the heating devices to the heating system of the heating system, the upper and lower pipes 11 are made.

 The device operates as follows.

 The coolant through the pipeline through the upper pipe enters the first section 1, sequentially passes through the upper tubular elements 2 and gaskets-loosers 9, causing irregular mode of movement of the coolant, through the pipe 10 of the last section 1 flows into the lower tubular elements 2, with each of them repeating the irregular heat transfer mode, characteristic in that in this mode the value of the coefficient of heat transfer from the heat transfer medium to the tubular element 2 is several times higher than in the regular mode. The irregular mode of movement and heat transfer is achieved due to the presence of gaskets-rippers 9, which increase the temperature at the walls of the tubular elements 2 and the overall heat transfer of the device.

 The successive passage of the heat carrier through the upper and lower tubular elements 2 of the gasket-ripper 9 also leads to equalization of the temperature of the heating device in all its parts, and ultimately to an increase in its heat transfer.

 Using the proposed heating device in comparison with the prototype allows two-sided use of the heat transfer surface, which increases the density of the heat flux with more than halving the consumption of material.

 The use of external sectional bolted connections facilitates the maintenance of the proposed heating devices and increases their service life.

 These heating devices can be interconnected both in series and in parallel, and their insignificant height and depth facilitates application in residential, public and industrial buildings, improves the aesthetic appearance.

 The use of various materials for the manufacture of heating devices, for example, cast iron, steel, aluminum, ceramics, etc., as well as its more rational design, reduces material and labor costs by 5 times.
