The casings of the known convectors contain front, rear, side and upper walls, while in the upper wall of the casing there are air outlets forming a grate, the rear wall of the casing is connected to brackets having means for attaching the casing to the wall of the heated room, as well as means for mounting the heat exchanger on brackets, and the brackets and the rear wall of the casing essentially form a static-load convector frame (RU 2145691 C1, 02.20.2000; RU 2272224 C2, 03.20.2006; RU 2339883 C2, 11.27.2007; RU 2344351 C1, 01.20.2009; RU 2381424 C1, 10.02.2 010; RU 2363898 C1, 08/10/2009; RU 16306 U1, 20.12.2000; RU 2273804 C1, 10/10/2006).

The heat exchangers of known convectors contain a curved pipe with fins, forming a supply branch (supplying coolant to the convector) and a branch (taking the coolant away from the convector), while, in the supply branch of the pipe, there is a thermostat housing with pipes connecting sections of the falling branch to the housing thermostat, the housing has a pipe under the thermostat, extending outward from the heat exchanger pipe, with the supply and outlet branches of the pipe communicating with each other bypass som located on the part of the heat exchanger remote from the body of the thermostat or located at the junction of the thermostat with the falling branch of the heat exchanger pipe (RU 2145691 C1, 02.20.2000; RU 2272224 C2, 03.20.2006; RU 2339883 C2, 11.27.2007; RU 2344351 C1, 01/20/2009; RU 2381424 C1, 02/10/2010; RU 2363898 C1, 08/10/2009; RU 16306 U1, 12/20/2000; RU 2272224 C1, 04/10/2006).

Well-known convectors do not meet the new requirements for the development of projects of energy-saving residential buildings, since they do not take into account the possibility of apartment-based metering of heat consumption and the possibility of introducing a metering system and payment for heating premises depending on the amount of heat consumed. As a result, heat consumers, as practice shows, significantly overpay management companies for the consumption of the amount of heat that they did not spend.

From a technical point of view, well-known convectors do not fully meet modern requirements for heat consumption, its accounting, heat transfer efficiency and material consumption. The latter is due to the fact that in the casings of known convectors there are nothing unreasonable in volume of large cavities and sinuses in which heated air plugs are formed, which are thermal insulators. Such heat insulators inhibit convective heat transfer between the fins of the heat exchangers and the weak laminar flow of heated air passing through it, which has a slight draft in the casing. Also known convectors do not meet the requirements for compactness. Recently, these requirements have been significant in terms of placing convectors in a heated room, given that convectors in a room are parts of the interior of a room.

The above set of features of each variant of the convector made it possible to create more flat compact versions of convectors with increased air traction in their casings. A feature of the casing for these versions of the convector is the presence of side partitions in it, which made it possible to direct the air flow around the heat exchanger through a narrower duct, reduce the length of the air column, reduce its width and increase its height, which increased the air draft in the casing. The increase in air draft in the casing made it possible to increase the heat transfer intensity and provided the possibility of heat extraction from the heating system with lower energy costs that are associated with the supply of the coolant to the heated room. The combination of the stated features of convectors and its components made it possible to create variants of convectors with the least amount of air sinuses in the casings, the least possibility of air retention in such sinuses, which ultimately made it possible to increase the laminarity of the process of air flow around the fins of the heat exchanger and air draft in the casing. The heat exchanger options for these convectors provide the manufacturer with the option to select various heat meters and temperature controllers on them, as well as the ability for the consumer to install an acceptable heat exchanger option for him, including the ability to pay for the heat consumed. It is essential that the consumer selects an individual heat saving scheme by providing control of heat consumption and the ability to control the passage of heat carrier through the heat exchanger. This creates the possibility of individual apartment-by-apartment metering of the used heat by means of meters installed on convectors in order to exclude the possibility of overpaying for heat by the consumer.

The first variant of the convector (Figs. 1-3) comprises a casing 1 having a front, rear, side and upper walls 2-6, respectively, as well as side partitions 7 and 8 of the convector frame located in the casing (Fig. 2). The frame also includes the rear wall 3 of the casing.

Inside the casing is a heat exchanger 9 made of a pipe with fins 10 on it. The pipe forms a supply branch 11 (for supplying the heat transfer medium to the convector heat exchanger) and a discharge branch 12 located parallel to it (for removal of the heat transfer medium from the heat exchanger). The pipe also has a bent portion 13 in the zone of transition of the supply branch to the discharge branch. The bent portion 13 of the pipe is located inside the casing. The ends 14 of the heat exchanger pipe are located outside the casing. The supply and outlet branches 11 and 12 of the pipe are connected by a bypass 15 located in the cavity of the casing on the opposite side from the bent portion 13 of the pipe. On the bent portion 13 of the pipe is installed and fixed heat meter 16. The counter contains a housing with a display having a screen for digitally displaying the amount of heat taken by the convector; a thermal sensor is installed in the housing, which records the temperature of the supply pipe. The counter works in conjunction with another sensor that records the room temperature, and in the absence of an air sensor, the room temperature is assumed to be normal by default.

On the supply branch 10 of the heat exchanger pipe, a temperature controller 17 is installed or cut into this branch, designed to regulate the flow of heat carrier into the heat exchanger. The body of the thermostat 17 is made integral with the bypass 15, which is connected and communicated with the branch branch 12 of the heat exchanger pipe.

The fins 10 are located in the middle part of the casing between the side walls 7 and 8 of the casing. The heat exchanger is connected to the rear wall 3 of the frame by means of brackets 18. Each bracket 18 is rigidly connected to an adjacent side partition. In the upper wall 6 of the casing made air outlet 19 (Fig.17).

The brackets 18, the side walls 7 and 8, and the rear wall 3 connected to each other represent essentially a convector frame. The rear wall 3 of the frame is welded to the brackets 18 to which the partitions 7 and 8 of the frame are welded.

At the bottom, the casing has an open air intake 20 from below (Fig. 1), and each bracket 18 has a flange 21 in the upper part, with which the edge 22 of the upper wall 6 of the casing bent inwardly engages.

The second variant of the convector (Figs. 4-6) contains the mentioned features of the first variant of the convector, except that the second variant does not have a heat meter. This convector option is provided to enable individual selection of the calculation for the heat consumed.

The third variant of the convector (Figs. 7-9) contains the features of the first variant of the convector, except that the bypass 15 of the third variant of the convector is not connected and is not connected to the thermostat 17. Bypass 15 of the third variant of the convector (Fig. 8) is connected and communicated with the supply and the branch pipe 11 and 12 of the heat exchanger pipe and is located up to the temperature controller 17 along the direction of the heat carrier, the direction of which is shown in Fig. 8 by an arrow. Moreover, the bypass 15 in this embodiment of the convector is located outside the casing.

The fourth variant of the convector (FIGS. 10-12) contains the features of the first variant of the convector, except that there is no heat meter on the bent portion 13 of the heat exchanger pipe. In the fourth embodiment of the convector, a heat meter 16 is installed on the outlet branch 12 of the heat exchanger pipe (Fig. 11) after bypass 15 in the direction of the heat carrier leaving the branch 12 (the direction of the heat carrier is shown by an arrow).

All versions of the convector have cavities 23 and 24, in which, respectively, the curved part 13 of the pipe is located on one side of the convector and the temperature regulator 17 on the other side of the convector. In each variant of the convector, a thermostatic head 25 is installed on the thermostat 17, which provides automatic adjustment of the coolant supply to the heat exchanger and, accordingly, adjustment of the heat supply to the heated room.

The convector casing (Fig. 13) is made of a stamped sheet bent in two planes so that parts of the sheet form the front, side and top walls. The casing is mounted on the convector frame, which contains vertically oriented side partitions 7 and 8 located in the casing (Fig. 2), the rear wall 3 and the brackets 18, while the rear wall 3 is detachably connected to the casing and has a functional relationship with it, and the frame is connected with a casing with the possibility of removing the casing from the frame.

A central cavity 26 (Fig. 13) is located between the partitions under the heat exchanger fin plate 9 located in this cavity. Between the partition 7 and the adjacent side wall 4, a cavity 23 is formed for the heat exchanger element located in it, in particular, under the bent portion 13 of the heat exchanger. Between the partition 8 and the adjacent side wall 5, a cavity 24 is formed for the heat exchanger element located in it, in particular, for the thermostat 17. In the side wall 4, in its lower part, a recess is made for the heat meter located in it with a display.

Bottom of the casing has the aforementioned open airway 20 from the bottom of the convector (FIGS. 1, 14) formed by side partitions, side, front and rear walls. With the rear wall 3 of the casing and the side walls 7 and 8 are connected brackets 18 having a complex shape. Each bracket 18 in its lower part has a tool tray 27 (Fig.14, 22) in the form of two inclined cutouts open from above. Lodgements 27 are intended for the location of the branches 11 and 12 of the heat exchanger pipe in them. Each bracket 18 is rigidly connected by welding to an adjacent side partition 7 or 8. The interconnected brackets 18, side partitions 7 and 8 and the rear wall 3 represent essentially a convector frame. Each bracket 18 has openings 28 (Fig. 13) for the fastening elements of the convector frame to the wall of the heated room located in them.

Each bracket 18 of the frame has a flange 21 (Fig. 14), with which the inwardly curved edge 22 of the upper wall 6 of the casing is engaged. The lower edge of the front wall 2 has an inwardly flanged 29 (Fig. 13), which is connected by screws to the brackets 18. The side walls 4 and 5 and the upper wall 6 of the casing have flanges 30 (Fig. 15), bent inward of the casing, with the flanging 30 the upper wall by spot welding is connected to the flanges 30 of the side walls 4 and 5 in the upper part of these walls.

The convector heat exchanger (first variant, FIGS. 23-24) contains a curved pipe with fins 10 on it, the pipe forms a supply branch 11 and a branch branch 12 located parallel to it. Also, the pipe forms its curved part 13 in the transition zone of the supply branch into branch branch. The pipe branches are connected by bypass 15. With one of the pipe branches, in particular, with the supply branch 11 of the pipe is connected to the housing 31 of the thermostat. The housing 31 has nozzles 32 and 33 (Fig.24), designed for its connection with the supply branch 11 of the pipe. The housing 31 also has a pipe 34 into which the thermostat 17 is screwed. The pipe 34 extends away from the pipe branch 11 to which the thermostat housing 31 is connected. The pipe 34 passes through the hole 35 (Fig.15), made in the front wall 2 of the casing.

On the bent section 13 of the heat exchanger pipe, a plate 36 is fixed with holes 37 (Fig. 26), by means of which a heat meter 16 is fixed on the plate 38 (Fig. 2). The plate 36 is fixed by a weld seam 38 (Fig.23), located around the contact point of the plate with the curved part 13 of the pipe. A second plate 40 is connected to the plate 36 by welding 39 (Fig. 24), which by welding 39 is connected to the supply branch 11 and the branch branch 12, while the second plate 40 is located on one of the sides of the heat exchanger pipe bent in the vertical plane so that it adjacent to the branches 11 and 12 of the pipe on one side of these branches.

The convector heat exchanger (second variant, FIGS. 25-27) contains the features of the first convector variant, with the exception that in the second convector variant, the bypass 15 is connected to the inlet and outlet branches 11 and 12 of the heat exchanger pipe, while the bypass is located behind the thermostat 17 in the direction of travel the heat carrier shown by the arrow emerging from the outlet branch 12 of the heat exchanger pipe.

The convector heat exchanger (third option, FIGS. 28, 29) contains the features of the first heat exchanger option, except that in the third embodiment, the heat meter 16 is installed on the outlet branch 12 of the pipe after bypass 15 in the direction of the heat carrier shown by the arrow exiting the outlet branch 12 heat exchanger tubes, while the curved part 13 of the pipe is smooth, without a plate for installation on the curved part of the heat meter. In this embodiment, the counter 16 registers the current value of the temperature of the coolant at the outlet of the convector and transfers it to the heat logger. The absolute value of the heat used by the convector per unit of time is taken into account by the recorder taking into account the temperature of the air in the heated room.

The convector heat exchanger (fourth variant, FIGS. 30, 31) contains the features of the first convector variant, with the exception that in the fourth convector variant the bent part of the heat exchanger tube is smooth without plates for attaching the heat meter. In this embodiment, the heat exchanger does not have a heat meter.

The first version of the convector works as follows. Under pressure, the coolant is supplied to the supply branch 11 of the heat exchanger in the direction of the arrow to the left in FIG. 1 and the coolant enters the temperature regulator 17. The temperature regulator 17, adjusted to a predetermined air temperature in the heated room, passes the coolant to the left along the supply branch 11, which heats this branch and heats the plate 10 fins of the pipe. As a result, the air surrounding the plates 10 is heated from the plates and rises up the central cavity 26 of the casing, from where it enters the heated room through the air outlet 19 (Fig. 17) in the upper wall 6 of the casing. Due to the temperature difference in the zone of the air inlet 20 (Figs. 1, 14), in the central cavity of the casing in the zone of the air outlet openings 19, as well as the temperature in the heated room, air draft is created in the cavity 26 of the casing. The higher the air cavity 26 and the less depth the convector cover has, the stronger the air draft is created in the cover, the more intensive is the heat exchange process in the heat exchanger, meaning the heat transfer by the plates 10 to the air coming from below the room. In the case of excess temperature, the thermostat 17 is activated, which moves its valve in the housing 31 (Fig. 27), partially closes the bore in the housing and thereby regulates the flow rate of the heat carrier in the supply branch 11 of the heat exchanger. The thermostatic head 25 limits the movement of the valve of the temperature regulator 17 to the specified limits, by which the set room temperature is set, and the head 25 is automatically activated every time the temperature and flow rate of the coolant are outside the set limits. In the case of excessive air temperature in the room, the head 25 presses on the control element of the thermostat and the thermostat valve closes the flow area in the housing 31, while the excess coolant under pressure is passed through bypass 15 to the outlet branch 12 of the convector and enters the general heating system of the building. The heat meter 16 captures the amount of heat taken by the heat exchanger from the heat carrier passing through it.

The layout of the convector is made in such a way that, in the cavities 23 and 24 of the casing, there are, respectively, a heat meter 16 and a temperature controller 17, and pipe sections with fins are located in the middle cavity 26 of the convector. This made it possible to reduce the length of the cavity 26, increase the air draft in it, accelerate heat transfer, and make heat transfer more efficient by accelerating the flow of air around the fins 10. When the first variant of the convector is working, a visual control of the heat consumption is carried out by reading the heat consumption indicator from the display of the counter 16. Taking into account the obtained indicators, the consumer controls the heat consumption by the thermostatic head 25.

The work of the second variant of the convector is carried out similarly to the work of the first variant of the convector, except that the second variant of the convector works without a heat meter and the heat consumption of this variant of the convector is not controlled.

The work of the third variant of the convector is carried out similarly to the work of the first variant of the convector, with the exception that in the third embodiment, the coolant bypass bypass 15 (Fig. 8) is indirectly dependent on the operation of the thermostatic head 25 and thermostat 17, since the coolant is bypassed before it enters the thermostat 17. This variant of the convector is used to simplify its manufacture, since the bypass 15 taken out of the convector casing allows welding of the end parts of the pipe branches 11 and 12 heat exchanger, respectively, to the nozzle of the housing of the thermostat 17 and to the middle part of the outlet branch 12 of the heat exchanger pipe. In this case, there is no need to use the case of the thermostat, made at the same time with the bypass.

The work of the fourth variant of the convector is carried out similarly to the work of the first variant of the convector, except that in the fourth embodiment, the heat meter 16 (Fig. 11) registers the amount of heat passing through the convector at the outlet of the heat exchanger in the outlet branch 12 of the heat exchanger. This variant of the convector has a simpler design that positively affects the dimensions of the convector, since in this embodiment the heat meter 16 has a more compact design, while eliminating the need for fastening the heat meter to the heat transfer pipe. In this variant of the convector, it is provided that the heat meter 16 registers the current value of the coolant temperature in the outlet branch 12 of the heat exchanger pipe, which is compared with the current value of the air temperature in the heated room and the consumption of heat consumed by the convector is calculated from the results of the comparison.

The operation of the convector casing is described in the work of the first variant of the convector. Mounting the convector on the wall of a heated room is as follows. Mark up on the wall, under the fastening elements of the convector to the wall of the heated room and install fastening elements with heads on the end in the wall. Mount the convector assembly (as part of its frame, casing and heat exchanger) onto the fasteners fixed in the wall by inserting the fasteners into the holes 28 of the brackets (Fig. 13). Then weld the inlet and outlet branches of the heat exchanger with the inlet and outlet pipes of the room heating system.

The heat exchanger (first option, Fig.23) works as follows. Thermostatic head 25 (Fig. 28) of thermostat 17 (Fig. 23) sets the required air temperature in the room. The coolant is passed under pressure through the supply branch 11 of the heat exchanger pipe. As a result, the plates 10 are heated and transfer heat to the washer plates to the air. In this case, the air limited by the side walls 7 and 8 of the casing rises upward by an air column located exclusively above the plates 10 and between the walls 7 and 8, which eliminates the dispersion of air in the casing and significantly increases the heat transfer rate.

When the set air temperature in the room is reached, the thermostatic head 25 is triggered, which restricts the movement of the thermostat rod 17. When the thermostat rod moves to extend or retract, the flow area in the thermostat housing decreases or increases, while less or more heat carrier enters the heat exchanger, moreover, if necessary, excess coolant is bypassed bypass 15 of the heat exchanger in the branch branch 12 of the heat exchanger pipe. In this case, the coolant from the supply branch 11 enters the bypass 15 through the cavity of the housing 31 in which the thermostat 17 is installed. The described operation of the heat exchanger is continuous. In the process of operation of the heat exchanger, the heat meter 16 registers the amount of heat taken by the convector from the coolant.

The convector heat exchanger (second option, FIG. 24) works in the same way as the first heat exchanger option, except that the coolant enters bypass 15 directly from the supply branch 11 of the coolant pipe, which is acceptable for heat exchangers designed for reduced coolant pressure in the total heating system.

The convector heat exchanger (third option, FIG. 25) works in the same way as the first convector option, except that in the third option, a counter 16 is installed on the outlet branch 12 of the heat exchanger and reads the current value of the coolant temperature at the outlet of the convector and transmits this value to the heat recorder.

As a result, the layout of the four versions of the convector made it possible to reduce the dimensions of the convector, making it more compact and ergonomic, by providing the possibility of a relatively more intense heat transfer between the heated room and the heat exchangers (with equal pressure in the heating system). Thanks to the indicated design features of the convector, it was possible to significantly reduce the thickness of the heat exchanger, the depth of the casing and the material consumption of the convector. The compactness of the convector made it possible to improve its ergonomic indicators with respect to the possibility of the location of this type of convector in the interiors of rooms. This means that convectors flattened in the form of parallelepipeds, located according to standard schemes in heated rooms, are stationary parts of the interior of the room, which are subject to increasingly increased requirements, based on the conditions of interaction of a person with them in a limited space. By reducing the depth of the casing, the air draft in it and the heat transfer intensity are increased, which positively affected the energy intensity of the room heating system.
