This convector is designed for low power, and the increase in its power is associated with certain structural changes in the dimensions of the casing and heat exchanger of a nonlinear nature, since with a significant increase in power, not only the structures and dimensions of these nodes change, but also the relative position of these nodes with respect to each other. When creating a number of modifications of convectors of high power, the problem arose of maximizing the unification of convector units and elements of these units in order to reduce production costs.

The technical problem of this floor heating convector to be solved is the creation of a universal and maximally unified high-power convector.

The problem is solved in that in the floor heating convector containing a casing having upper, side, front and rear walls, a heat exchanger installed in the casing, having a pipe, an inlet pipe end part for introducing coolant into it and an outlet pipe end part for outputting from it coolant, while the heat exchanger pipe has branches located along the casing with heat transfer plates fixed to them, forming heating elements with the pipe branches, which are interconnected and installed in a row, o forming at least one tier of heating elements, - the end parts of the pipe in the form of a convector on the side are offset to the rear or front walls of the casing from the vertical axis of the convector, the ends of the pipe are located between the front and rear walls in the middle of the convector, depth ratio A convector to its height H is selected from the condition A / H = 0.1 ÷ 0.7, the ratio of the number of tiers Yang of heating elements to the number of Ne heating elements is selected from the condition Yan / Ne = 0.1 ÷ 1.0 at nominal heat flux Qnu convector within about 3.6 to 14.6 kW.

In the first embodiment, the convector has Qn = 3.6 ÷ 5.6 kW, Jan = 1 and Ne = 2 ÷ 4, the ratio A / H = 0.5 ÷ 0.7.

In the second embodiment, the convector has at Qnu = 5.6 ÷ 8.6 kW, Jan = 1 ÷ 2 and Ne = 4 ÷ 8, the ratio A / H = 0.35 ÷ 0.5,

In the third embodiment, the convector has Qn = 8.6 ÷ 10.6 kW, Jan = 2 ÷ 3 tiers and Ne = 8 ÷ 12, the ratio A / H = 0.35 ÷ 0.5.

For all the presented versions of the floor heating convector, it contains a heat exchanger 2 installed in the casing 1 (Fig. 1), which includes a pipe 3 curved in mutually perpendicular planes, forming branches 4 of the pipe 3. The branches 4 are located along the casing and heat exchange plates 5 are fixed to them ( fins), forming with the branches 4 the heating elements 6 of the heat exchanger.

The essence of the presented technical solutions is explained mainly by the description of the first variant of the convector (Fig.1-6). The heating elements 6 of the convector (Fig.6) are communicated between each other by rounded sections 7 of the pipe, and in the side view of the convector, the heating elements 6 are arranged in such a way that they form rows 8 and tiers 9 (Figs. 6, 10). The pipe 3 has an input end part 10 for input into it and heating elements 6 of the coolant and an output end part 11 for outputting the coolant from the pipe 3 and from the heating elements 6. Each heating element 6 contains straight and rounded sections of the pipe 3.

The ratio of Jan - the number of tiers 9 of the heating elements 6 of the heat exchanger, to Ne - the number of heating elements in the first variant of the convector is optimal when the value of Jan / Ne = 0.25. This value is optimal only for this variant of the convector with a nominal heat flux Qnu = 3.6 ÷ 5.6 kW. The optimal value of Jan / Ne = 0.25 is between the minimum and maximum values of this parameter characterizing the design of the convector. It was found that for this option the optimal number of heating elements is in the range from two to four (Ne = 2 ÷ 4), and the optimal value of the ratio of the depth A of the convector to its height N is in the range A / N = 0.5 ÷ 0.7 . For example, with an optimal convector depth A = 400 mm, the optimal height H of this variant of the convector is 650 mm.

With the total number of Ne heating elements in all the presented convector variants ranging from four to sixteen units, the nominal heat flux Qnu from 3.6 to 14.6 kW was installed (Fig. 16), which most fully meets the technical requirements of construction.

In the second and all subsequent versions of the convector, in contrast to its first variant, the pipe sections 3 of the adjacent large sides 12 (Figs. 7-13) of the heating elements 6 are connected to each other by vertically arranged pipes 13 welded to these pipe sections from their end sides. the adjacent sides of the heating elements 6 are formed of gaps 14 (Fig.7).

In all versions of the convector, in side view, the input end part 10 (Fig. 6) and the output end part 11 of the pipe 3 are offset by a distance d from the middle part of the convector heat exchanger 2 towards the rear wall 15 of the casing 1 or towards the front wall 16 casing. Moreover, the inlet and outlet of the indicated parts 10 and 11 of the pipe are located in the Central part of the heat exchanger 2 and convector in the specified form.

The convector casing has side walls 17 and 18 (FIGS. 1, 7) and an upper wall 19 with a plurality of air outlet openings 20 formed therein.

The input end portion 10 of the pipe 3 (FIG. 6) and the output end portion 11 of the pipe 3 have extensions that include inclined pipe sections 21 and 22 and the vertical pipe sections 23 and 24 that are angled. At the ends of the vertical sections 23 and 24 of the input end part 10 of the pipe 3 and the output end part 11 of the pipe 3 of the pipe there are corresponding inlet and outlet openings.

Each version of the convector has a vertical axis 25, which is located in the middle of the convector in side view. Each heating element 6 is in communication with an adjacent heating element with a rounded pipe portion 26.

The casing of each variant of the convector includes an upper part 27 and at least one lower part 28. Parts of the casing are connected to each other and to the side walls 17 and 18 of the casing by flanges 29 of the side walls or panels of which the front and rear walls 15 and 16 are made. Flanging 29 are interconnected by connections 30, which can be detachable and one-piece (screw or rivet).

Modifications of the casing include at least one or two middle parts 31 of the casing (figure 2), which are similarly connected to the upper part 27 and the lower part 28 of the casing. The middle part 31 is also made of the aforementioned separate identical panels connected to the side walls of the casing and to each other in a similar manner.

The side walls 17 and 18 of the casing in each variant of the convector are made elongated in the lower side and perform, in addition to their main functions, the functions of the convector supports that are installed on the floor of the heated room.

Each variant of the convector has additional supports 32 (Fig. 1) connected to the casing and the heat exchanger 2, which are connected by similar connections 30 to the load-bearing elements of the convector, and are located between the side walls 17 and 18 of the casing. The front and rear walls 15 and 16 of the casing are made of horizontally located the aforementioned panels 33 connected to each other and the side walls of the casing.

Between the lower edges 34 of the casing and the floor 35 of the heated room, an air intake or air intake openings 36 are formed for access of cold air to the cavity of the convector casing.

Each variant of the convector has in its lower part brackets 37 fixed to the casing 1 (Fig. 6), by means of which the heat exchanger 2 is connected to the casing. Brackets 37 are located symmetrically on two opposite sides of the convector along its length and depth.

In the additional supports 32 (Fig. 3) of each variant of the convector, holes 38 are made, which are intended for fastening the convector to the floor of the heated room, with each variant of the convector having handles 39 (Fig. 2) installed in the holes 40 of the side walls. An air damper plate (not shown) is attached to these handles to adjust the air movement in the cavity of the convector casing. Flanging 29 panels 33 are connected to the side walls with rivets 41.

Each variant of the convector has a depth A (FIG. 2) equal to the distance between the front wall 15 and the rear wall 16 of the casing, and also a height H (FIG. 1) equal to the distance from the floor 35 of the heated room to the upper wall 19 of the casing, as well as the length L (figure 1), which is equal to the distance between the side walls 17 and 18 of the convector casing.

Experimentally, a number of large-sized large-sized convectors of the same type were installed - five options (models) of floor convectors, which are presented in the table (Fig. 16). Convector KPVK15-4.6K with parameters Qnu = 3.6 ÷ 5.6 kW, Jan = 1 and Ne = 2 ÷ 4, A / N = 0.5 ÷ 0.7. Convector KPVK15-7.5K with parameters Qnu = 5.6 ÷ 8.6 kW, Jan = 1 ÷ 2, Ne = 4 ÷ 8, A / H = 0.35 ÷ 0.5. Convector KPVK15-9.5K with parameters Qnu = 8.6 ÷ 10.6 kW, Jan = 2 ÷ 3 tiers and Ne = 8 ÷ 12, A / N = 0.35 ÷ 0.5. Convector KPVK15-11.0K with parameters Qnu = 10.6 ÷ 12.6 kW, Jan = 2 ÷ 3 tiers and Ne = 8 ÷ 12, A / H = 0.1 ÷ 0.35. Convector KPVK15-13.5 with parameters Qnu = 12.6 ÷ 14.6 kW, Jan = 3 ÷ 4, and Ne = 12 ÷ 16, A / H = 0.1 ÷ 0.35.

In accordance with the required nominal heat flux Qn, which is necessary for a certain heated volume of the room, the convector designation is selected according to the set heat flux value from the indicated table of convector parameters and the dimensions of the casing are determined. According to the selected casing, a heat exchanger is selected with a certain number of tiers of heating elements and the number of heating elements in the heat exchanger corresponding to the established nominal heat flux Qnu.

Mount the convector on the floor of the heated room and attach it to the floor 35, for which purpose fasteners are introduced into the holes 38 (figure 3) of the brackets 32 (figure 1) and the floor holes (not shown) and fix them in these holes.

The coolant is fed into the opening 42 of one end of the pipe 3 and through the inlet end part 10 of the pipe 3 (FIG. 3), the convector coolant enters the heat exchanger 2, which transfers heat to the air cavity of the casing 1 and heats the air therein. This creates a temperature difference in the lower and upper parts of the casing, since cold air enters the casing 36 through the air inlet 36 (Fig. 1), and the air heated by the heat exchanger located in the heat exchanger zone and above it rises and carries the cold air. At the same time, an air draft is created in the casing, which, if necessary, is regulated by a plate air damper installed in the casing by turning the damper with handles 39 around its longitudinal axis.

Heated air leaves the casing through the air outlet 20 of the upper wall 19 (Fig.6, 15). From the outlet 43 of the pipe 3 (Fig.6) through the output end part 11 of the pipe 3, the coolant is discharged to the heating main.

There is a method for assembling a convector, including the operation of connecting the panels 33 of the casing (figure 2) with the side walls 17 and 18, with each other and with the upper part 27 of the casing, as well as the operation of fastening the heat exchanger 2 in the casing (figure 1).

An essential feature of the method is that the first operation of the casing assembly is performed first and the side walls 17 and 18 of the casing are connected to the panels 33 of the front and rear walls 15 and 16 of the casing (FIG. 2). Then the second operation is performed - in the inverted form, the upper part 27 of the casing (FIG. 6) is installed on the mounting floor with the air outlet openings 20 down. After that, install the lower part of the casing 28 on the inverted upper part 27 of the casing, join these parts with docking places and firmly connect them with screws (not shown). If, in addition to the aforementioned connecting parts, the convector casing includes middle parts 31 of the casing, then the inverted upper part 27 of the casing is joined to one of the middle parts of the casing.

After carrying out these operations, the heat exchanger 2 is mounted on the brackets 37 of the casing (Fig.6).

Next, the convector is turned 180 degrees and installed by the side walls 17 and 18 and additional supports 32 on the floor 35 of the heated room (figure 1).

After assembling the convector, the inlet and outlet parts 10 and 11 of the heat exchanger pipe 3 occupy a central place with respect to the front and rear walls 15 and 16 of the casing in a side view (Fig. 6), which, firstly, facilitates the assembly of the convector, since the convector casing during assembly, it can be rotated relative to the heat exchanger by either side, secondly, it allows the casing to be unified for all versions of the convector, and thirdly, this design unifies the connection of the convector to the heat network.

If it is necessary to reduce or increase the power of the convector, the height H of the convector is changed by changing the number of panels in the casing. In this case, the number of Yang tiers 9 of the heating elements 6 of the heat exchanger 2 or the number of heating elements in the tier are changed.

Since all the heating elements 6 are made identical in shape, the heating elements 6, which are a single rigid unit, a tier 9, installed in a row 8 and connected to each other by heat transfer plates 5, are easily removed from the brackets 37, installed and fixed on them.
