The convector contains a casing made of a metal sheet, formed by two connected parts, which are the front part 1 (Fig. 4), which has a rectangular box shape, and the rear part 2 of the casing connected to the front part of the casing (Fig. 5). The front part of the casing comprises a front wall 3 (Fig. 4), a left side wall 4, a right side wall 5 and an upper wall 6, in which air outlets 7 are made (Fig. 3). The rear part 2 of the casing (Fig. 5) contains a heat-reflecting rear wall 8 of the casing, which reflects heat due to the form of its execution and attachment to the wall of the heated room. The fastening of the heat-reflecting back wall 8 on the wall of the room (not shown) is made with an air gap between the wall and the heat-reflecting back wall 8.

The rear wall 8 contains brackets 9 (Fig. 5) with recesses 10 in the lower part of the brackets. The recesses 10 are used for fixing and hanging on them the pipes of the convector heater. In the upper part of each bracket 9, a support 11 is made for positioning the upper wall 6 (Fig. 4) of the front part of the casing on it. The rear wall 8 and the front wall 3 of the casing are made interchangeable, they have the same universal shape. The left side wall 4 and the right side wall 5 also have the same shape and are made universal.

Brackets 9 (Fig. 5) are rigidly connected to the rear wall 8, which along its perimeter has flanges 12 directed to the inner side of the casing, located in the casing in its working assembled position.

Between the supports 11 there is a stop 13 (Fig. 5), made on the rear of the casing, interacting with the front wall of the casing and made on the other, middle bracket 11. The stops 13 also have extreme supports 11, the lower parts of the brackets 9. Each stop 13 has the shape of a platform, abutting in the working position of the convector against the front wall 3 of the casing to give it resistance to bending from external influences.

In each side wall of the casing (Fig. 4) a pair of circular holes 14 are made, which are located one above the other, while above the upper hole 14 there is a third circular hole 15 for the location of the air damper rotation handle (damper not shown) located in the cavity casing for regulating the upward flow of heated air. In the absence of a damper, hole 15 is closed with a plug 16.

The front wall of the casing and its rear wall are made from the inside and outside with vertically oriented protrusions 17 (Fig. 4, 5), which are located between the vertical recesses 18 to improve the movement of the upward flow of heated air from the heater towards the air outlet openings 7 of the upper wall. The rear wall of the casing has holes (not shown) or other known means for attaching it to the wall of the heated room.

The convector heater installed in the casing has two identical pipes 19 and 20 (Fig. 6) located parallel to each other, one of which is upper and the other is lower, located under the upper pipe. Pipes 19 and 20 have modules 21 and 22 at their ends, the pipes are connected and connected by modules, and they are also connected by heat exchange plates 23 located along the length of the pipes, rigidly connected to pipes 19 and 20.

One left module 21 is connected to the left ends of the upper and lower tubes 19 and 20 through a pair of hollow bushings 24 and 25 of module 21. Another right module 22 is connected to the right ends of pipes 19 and 20 through a pair of hollow bushings 26 and 27 of module 22. Bushings 24 and 25 are connected by a vertical tube 28. Bushings 26 and 27 are connected by a vertical tube 29 of the module 22.

Each bushing is put on the end of the corresponding heater tube (Fig. 11) and rigidly connected to it so that inside the bushing the end of the tube 20 forms a ledge that forms a cavity communicated with the cavity of the vertical tube 29 of the module.

Module 21 (Fig. 10) contains an upper blocking nipple 30 installed in the bushing 24 and a lower straight-flow nipple 31 installed in the bushing 25. The upper blocking nipple 30 has ends 32 and 33. The end 32 is intended for connection with a branch pipe (not shown) of the assembly the convector piping connecting the convector heater with the pipes of the heating system. The end 33 is made elongated and its elongated part is located in the sleeve 24.

The lower straight-through nipple 31 has ends 34 and 35. The end 34 is intended for connection with the pipe of the convector piping unit connecting the convector heater with the heating system pipes, and the end 35 is located in the bushing 25. All cavities of the mentioned bushings, tubes and pipes are interconnected.

The openings of the bushings 26 and 27 of the module 22 (Fig. 10) in the operating position of the convector are closed, respectively, by the air outlet valve 36 and the blind plug 37. In Fig. 1, 3, 6, 9, 10, position 38 shows the connecting nuts, which are used to connect the convector heater with its strapping unit (the strapping unit is not shown, it is not included in the convector design).

Each sleeve has a thread 39 inside (Fig. 11), into which (except for the plug 37) a nipple 30 or a nipple 31, or an air vent valve 36 having the same thread with thread 39 of each sleeve can be screwed. Between the end of each bushing facing the extreme heat transfer plate 23 and this plate, a recess 40 is formed (Fig. 9), which is located in the recess 10 of the bracket 9 in the convector's operating position, which prevents the heater from displacing relative to the rear heat-reflecting wall 8 of the casing.

The end of each sleeve is located in the contour of the corresponding hole 14, close to this hole on either side of the casing. This arrangement is designed to allow easy tool access to nipples 30 and 31, air vent 36, and blind plug 37 from either side of the casing when it is necessary to remove any of these assemblies from the heater and install another or new assembly without removing the casing.

The convector works as follows. The heat carrier is supplied through the strapping unit (not shown) under pressure to the module 21 (Fig. 6, 10). The coolant passes the blocking nipple 30 of the module 21, the upper sleeve 24, the upper pipe 19, the sleeve 26 of the module 22, the heater tube 29, the lower pipe 20 and exits under pressure through the lower nipple 31 into the outlet pipe of the convector piping and the heating system. When the coolant moves, the elongated end 33 of the nipple 30 closes (blocks) the channel of the tube 28 and the coolant moves in the above direction.

The pipes 19 and 20 are heated, and the heat from them through the heat exchange plates 23 heats the air in the cavity 39 of the casing (Fig. 2). The heated air rises upward, exits through the air outlets 7 (Fig. 3) in the upper wall 6 of the casing, and the heated air entrains cold air (shown by arrows in Fig. 1) under the convector casing. Cold air in the direction of the arrows in FIG. 1 enters the casing through the bottom opening of the casing, open from below, is heated in the casing by a heater, and the process is repeated.

When the air heated in the casing passes in the upward direction, it contacts the heat-reflecting rear wall 8 of the casing (Figs. 2, 5), and the heating of the wall of the heated room is insignificant in comparison with the casing, which does not have a heat-reflecting wall. The rest of the heat is reflected from the rear wall 8 of the casing and is discharged through the air outlets 7 of the upper wall into the heated room. In the cavity of the casing, a laminar mode of air movement is established.

The drawings (Fig. 1, 6) show a convector connected to the pipes of the heating system on the left side. To connect the convector to the pipes of the heating system, which are located to the right of the convector, remove the nipples 30, 31 on one side of the convector and remove the air outlet valve 36 and plug 37 on the other side of the convector, swap them, placing them in the bushings in a mirror image with respect to the original position ... Connect pipes 19 and 20 of the heater to the branch pipes of the piping units of the heating system as described on the left side of the convector and start the convector in the manner described above.

At the other end of the heater (Fig. 1), the hole located on the tube of one bushing (communicated with the hollow elongated end 33 of the nipple) is closed with an air outlet valve 36, and the hole of the adjacent bushing fixed on the other tube of the heater is closed with a blind plug 37. However, the design of the convector allows the use of various combinations of the relative positions of the air outlet valve 36, the blind plug 37, the blocking nipple 30 and the lead-through nipple 31. Each of these units of the heater, depending on the direction of movement of the coolant, can be installed in any appropriate combination. For example, if at the other end of the heater the hole in the bushing attached to the pipe and connected to the elongated end of the nipple is closed with a blind plug, then the hole in the adjacent bushing attached to the other pipe of the lower bushing will be closed with an air bleed valve. Or, in one, for example, the upper bushing of one of the pairs of bushings, a lead-through nipple can be screwed, and a locking nipple can be screwed in the other lower bushing of this pair. The heater is symmetrical; it is designed for both left and right connection of the convector to the piping of the heating system. It is essential that the modules 21 and 22 (Fig. 6) at the ends of the heater tubes are made interchangeable and each module is located in the cavity of the casing.

The design of the convector described above significantly increases its versatility, allowing the convector to be connected to the left and right using the same universal means.

During operation, part of the heat from the casing heated in the cavity is dissipated through the front wall of the casing into the heated space of the room. Another part of the heat from the air heated in the casing is absorbed by the back wall of the casing, which prevents a significant amount of heat from being removed towards the wall of the heated room and at the same time it works as a heat reflector. As a result, the stored amount of heat works for a laminar, more efficient mode of heated air outflow in the casing and for rising upward from the bottom of cold air. In this case, the efficiency of the casing is increased, and heat losses in the undesirable direction are reduced.

Also, due to the more reliable fastening of the front part of the casing on its rear part, the appearance of gaps between the wall of the heated room and the casing adjacent to it is excluded during the operation of the casing (as is the case in the prototype). The elimination of gaps eliminates the leakage of heated air towards the wall and the heated room through the gaps, which also retains the heated air in the casing and facilitates its discharge into the heated room through the air outlets. The amount of stored heated air positively works for the specified mode of outflow of heated air in the casing and increasing the efficiency of the casing.

Increasing the efficiency of heat transfer from the air heated in the casing to the heated room by stabilizing the movement of the heated air flow in the direction of the air outlets reduces heat losses for heating the wall and allows the stored amount of heat to be distributed more evenly in the heated room. At the same time, this advantage is obtained by using the blank of the front wall of the casing as the rear heat-reflecting wall, which have the same universal shapes, which is also associated with an increase in the versatility of the convector and a significant reduction in the labor intensity of manufacturing the convector.

The recesses in the rear wall of the casing improve the flow of heated air through the holes in the upper wall of the casing, which reduces heat transfer of heat to the wall of the heated room from the air heated in the casing. Depressions in the front wall of the casing also improve the flow of heated air through the openings in the upper wall of the casing, reduce heat transfer from the air heated in the casing to the heated room by dissipating heat from the front wall.
