The closest technical solution to this technical solution in essence and the achieved effect is a heating convector, including a heat exchanger installed in the casing with a thermostatic valve located in the recess of the casing, while the heat exchanger is made of a bent pipe having at least one inlet and one outlet straight sections with a radial transition between them, on which a thermostatic valve with a thermostatic head is installed, the inlet and outlet pipes of the thermostatic Valve threaded at the ends connected to the inlet and outlet portions of the pipe and the bypass pipe connected to the inlet and outlet portions of the pipe [4].

In this technical solution, as in technical solution [1], the thermostatic valve is installed on the radial transition of the pipe between its straight sections on the opposite side of the bypass pipe connecting the straight sections of the pipe, while the thermostatic valve is connected to the radius transition in the corner upper part of the transition. The location of the thermostatic valve determines the position of the heat transfer elements of the pipes from top to bottom - from the upper inlet pipe to the lower outlet pipe, which has a significant impact on the dimensions of the heating convector and heat transfer. The thermostatic valve is rigidly connected with the radial transition by means of union nuts that are screwed onto the threaded nozzles of the thermostatic valve, and the radial transition has an additional connection with straight-line inlet and outlet pipes by other additional union nuts, which significantly complicates the connection of the thermostatic valve with the inlet and outlet pipes and as a result, complicates the design of the heating convector as a whole.

The solved and achieved task of this technical solution is to improve the functional qualities, simplify the design and increase the compactness of the heating convector.

The stated technical problem is solved in that in a heating convector including a heat exchanger installed in the casing with a thermostatic valve located in the recess of the casing, the heat exchanger is made of a bent pipe having at least one inlet and one outlet straight sections with a radius transition between them, on which a thermostatic valve with a thermostatic head is installed, the inlet and outlet pipes of the thermostatic valve with a thread at the ends, connected to the inlet and outlet with the pipe sections and the bypass pipe connected to the inlet and outlet pipe sections — in one part of the radial transition of the heat exchanger pipe located offset to one side of the heat exchanger, a cut-out is made in which there is a thermostatic valve, and the pipe cut-out planes are mutually perpendicular to each other friend, the axis of the inlet pipe of the thermostatic valve and thermostatic head are aligned with the center of the semicircular part of the recess of the casing, and the radius of the semicircular part of the recess is chosen less than the radius of the ter oreguliruyuschey head.

The ends of the inlet and outlet sections of the heat exchanger pipe in the cutout zone are made conical with flare nuts mounted on them, while flanges are attached to the ends of these ends, which interact with the inlet and outlet nozzles of the thermostatic control valve.

The heating convector (Fig. 1) includes a heat exchanger 2 installed in the casing 1 with a thermostatic valve 3 located in the recess 4 of the casing, which has a radius part (Fig. 4) centered in the middle of the recess. The heat exchanger is made of a curved pipe having at least one inlet and one outlet straight pipe sections 5 and 6, on which heat exchange elements 7 are fixed. Between the mentioned sections 5 and 6 of the pipe is located its radial transition 8 (Fig. 2), on which a thermostatic valve 3 with a thermostatic head 9 is installed. The inlet and outlet pipes 10 and 11 (Fig. 9) of the thermostatic valve 3 are threaded at the ends and connected to the inlet and outlet sections 5 and 6 of the pipe. The axis 12 (Fig. 9) of the inlet pipe 10 of the thermostatic valve 3 and the axis 13 of the thermostatic head 9 are aligned with the center 14 of the radius part (Fig. 4) of the recess 4 of the casing 1. The recess 4 of the casing 1 is located between the longitudinal axis 15 of the side wall of the casing and its rear surface 16, intended for contact with the wall 17 of the heated room. The axis 18 (Fig. 9) of the outlet pipe 11 of the thermostatic valve 3 is located perpendicular to the axis 12 of the inlet pipe 10 of the thermostatic valve 3 towards the front wall 19 (Fig. 2) of the casing 1. The thermostatic head 9 is located coaxially outside the side wall of the casing of the recess 4 of the casing the radius of the recess (Fig.3, 4). The center 14 of the radius of the recess 4 is located on the axis 13 of the temperature control head 9 and on the axis 12 of the inlet pipe 10 of the temperature control valve 3 (Fig.3, 9). In one part of the radial transition 8 of the heat exchanger pipe (6), which is offset from the longitudinal axis 15 of the side wall of the casing towards the rear surface 16 of the casing, a cutout 20 is made in which the thermostatic valve is located.

The cutout 20 of the pipe (Fig.6) is made in mutually perpendicular planes 21 and 22 of the radial transition 8. Thermostatic valve 3 (Fig.9) is made with a seating surface 23 under the thermostatic head 9. The latter is removable. It can be either manual (for manual adjustment of the coolant), or automatic, which provides heat control depending on the room temperature.

In the presented example of the implementation of the technical solution, the heat exchanger also includes a bypass pipe 24 (Fig. 1) connected to the inlet and outlet sections 5 and 6 of the pipe, and the recess 4 is made in the side wall 25 of the casing 1 (Fig. 2, 4). The ends 26 and 27 of the inlet and outlet sections 5 and 6 of the heat exchanger pipe located in the cutout 20 are conical (Fig. 9), flanges 28 and 29 are fixed at the ends of these sections, and movable union nuts 30 and 31 are located on the conical ends 26 and 27. The temperature control valve 3 has a stem 32, which is movably located in the valve body in the direction of the longitudinal axis 13 of the temperature control head 9. The automatic temperature control head 33, as well as the manual temperature control head 9, after installing them on the seating surface 23 of the temperature control control valve 3 interacts with the movable rod 32 of thermostatic valve 3.

The design of the heating convector provides a method for its manufacture, which consists in first producing a predetermined shape of a heat exchanger from a pipe, in particular, at least forming two straight-line inlet and outlet sections 5 and 6 (Fig. 6) of a pipe with a radius transition 8. For this, the pipe billet having a rectilinear shape is bent in a predetermined plane until a radius transition 8 and at least two straight sections 5 and 6 are formed. Then, on straight sections of the pipe 5 and 6 put on heat exchangers 7 in a known manner and fix them on straight pipe sections 5 and 6, for example, by burning the pipe sections (inserting the mandrel into the pipe sections and increasing the outer diameters of these pipe sections). Next, one part of the radial transition 8 of the pipe is cut out and the ends of the pipe are crimped in the zone of the cutout 20 of the radial transition to form conical surfaces at the ends 26 and 27 of the inlet and outlet sections 5 and 6. After that, the flare nuts 30 and 31 are put on the conical ends 26 ( Fig. 7), then the flanges 28 and 29 are welded to the ends of the conical ends. Thermostatic valve 3 is inserted into the cutout 20 (Fig. 9), the nozzles 10 and 11 of the thermostatic control valve 3 are attached to the flanges 28 and 29. Thermostatic is controlled valve 3 and heat pipe inlet pipe ennika the wall of the heated premises (3). Then connect the casing 1 of the convector to the heat exchanger so that the axis 13 of the thermostatic head 9 (figure 2) was aligned with the axis 14 (figure 4) of the recess 4, which is made in the side wall 25 of the casing.

The convector works as follows. The coolant through the inlet section 5 of the pipe enters the cavity of the thermostatic valve 3, from which it is discharged along the outlet section 6 of the pipe. In this case, the thermostatic valve 3 automatically using the automatic thermostatic head 33 or using manual control by means of the thermostatic head 9 controls the flow rate of the heat carrier and, accordingly, the temperature of the heat exchanger. If this temperature is exceeded, the thermostatic valve reduces the flow rate of the coolant passing through the cavity of the thermostatic valve. In this case, the heat carrier from the inlet section 5 of the heat exchanger pipe is bypassed through the bypass pipe 24 to the outlet section 6 of the heat exchanger pipe.

The relative position of the convector parts, in particular, the location of the supply section 5 of the heat exchanger pipe between the wall 17 of the heated room and the discharge section 6 of the heat exchanger pipe, improves convection of the heated air and increases the functional qualities of the convector, while simplifying the design of the convector, increasing compactness due to the connection of the thermostatic valve with the sections heat exchanger tubes at its radius transition. The convector production technology has also been simplified.
