The sections are connected by means of through nipples. The technical result is an increase in the range of hot water heating means.

Description

Sectional Radiator

and section for him

Technical field

The technical solution relates to construction, and specifically to a sectional radiator for water heating, which can be mounted at glazed walls and display cases, as well as to a section for it.

State of the art

For installation along the glazed walls and showcases, convection water heating means are used, characterized by a small height, which in the mounted position, as a rule, do not exceed a height of 250 - 300 mm from the floor surface and in rare cases 300, 400 or 450 mm.

Convectors are known from such means. They are a set of zigzag fixed by welding on one or two parallel steel pipes, made of flexible steel sheet, or plates cut from it (Designer Handbook. Internal Sanitary Devices, edited by Ph.D. .G. Staroverova, Part 1, Heating, water supply, sewerage, Moscow, Stroyizdat, 1975, p. 44, continuation of table 12.1).

At the same time, steel pipes can be connected to the heating system both flow-through and in the case of using a two-pipe convector according to the end circuit, that is, one pipe is supplied and one second pipe when these pipes are connected from the convector side, opposite to its connection to the system heating.

These known convectors do not have effective heat transfer to the surrounding air, because their heat exchange elements have low heat conductivity with a small area of air washing.

The well-known radiator has more efficiency, which provides for an installation with an interference fit on two parallel steel pipes made of aluminum alloy heat-receiving elements, on which heat-transferring elements are fixed with a thermal contact elements with a developed surface for convection washing with air (RU 2273803 C1, IPC F24H 3/00, 2006).

However, due to the presence of loosening zones of heat-receiving elements with steel pipes, as well as heat-receiving and heat-transmitting elements, this technical solution is inferior in efficiency to a sectional radiator made of an aluminum alloy, including “bimetallic” ones, that is, filled with aluminum alloy steel frame, forming a system of channels of a sectional radiator.

The designs of such sectional radiators are well known.

For example, a sectional radiator of water heating is known, made in the form of a set of interconnected sections (RU 2172901 C1. MP F24H 3/06, 2001).

In this known solution, each section includes two transverse sections parallel to each other on opposite sides and having each straight channel extending between coupling pipes located on opposite sides of each transverse section and having each section with internal thread, as well as a longitudinal section connecting the transverse sections and associated with them in their middle zones, which has a longitudinal channel communicating from opposite sides with direct channels of the transverse sections.

To ensure heat transfer, each section contains an intermediate partition connecting the transverse sections and located perpendicular to them, in the middle part of which passes a longitudinal section, straight outer ribs, and two pairs of inner ribs.

The straight outer ribs extend perpendicularly on two sides of the intermediate partition and are interfaced with the intermediate partitions in the middle sections of the inner surface, forming the outer surfaces of the front flat surface of the radiator section. Two pairs of inner ribs extend from the intermediate partition into in opposite directions parallel to the straight outer ribs and do not extend beyond the cavities between the opposite outer ribs sections facing each other, the inner ribs being equally spaced relative to the adjacent straight outer ribs.

The sections are connected in series with each other through threaded nipples with external threaded sections, which are installed one for each pair of adjacent coupling pipes of two interconnected sections.

With insufficient flow of water coolant, its circulation occurs over several sections closest to the connection points. In the remaining sections, there is no circulation, which leads to their cooling and lower thermal efficiency of the sectional radiator for water heating.

This effect is especially pronounced when the water coolant moves “from bottom to top”, when the direction of the forced (pumping) circulation is opposite to the direction of the natural gravitational circulation. Accordingly, it is not possible to ensure the effective operation of an extended multi-section radiator of water heating, made in accordance with the above-described known technical solution and having a small height, which could make it suitable for installation on glazed walls and display cases.

Sectional water heating radiators of the described known construction are generally suspended on brackets mounted in the walls.

When installing heating devices near shop windows or glazed walls, or in another place inside a heated room, when they can only be fixed on the surface of the base, special supports are used, which are racks with heels. At the free ends of the racks, means are provided for securing the heater. As a rule, two similar supports are used, installed at a distance from each other. The essence of the technical solution

The technical result of this technical solution consists in expanding the arsenal of means for providing water heating of rooms in the form of an extended sectional radiator of water heating with uniform heating, which is small in height and can be mounted on a horizontal base, in particular near windows and glazed walls, as well as appropriate section for such a radiator.

- two pairs of inner ribs that extend from the intermediate partition in opposite directions parallel to the straight outer ribs and do not extend beyond the cavities between the facing sections of the straight outer ribs.

In a preferred embodiment, the main and end sections are provided with pairs of parallel additional inner ribs. located between the transverse sections. Moreover, pairs of additional inner ribs of the main and end sections continue beyond the transverse sections located below.

Each main section can be made of aluminum alloy. It is possible when each main section is made of aluminum alloy with pieces of steel pipes embedded in aluminum alloy that form the inner zones of the transverse sections.

The end section may also be made of aluminum alloy, and it is also possible that the end section is made of aluminum alloy with a frame of welded sections of steel pipes forming the inner zones of the conjugate longitudinal and transverse sections.

The main and end sections can have a height of 200 - 400 mm.

The radiator can be equipped with two plugs installed in the two coupling pipes of the end sections, as well as two caps mounted in the coupling pipes of the main section located on the radiator side opposite to the location of the side with the end section. Each foot is made with the ability to connect to the pipe supply or removal of water coolant.

The section of the water heating radiator, the design of which corresponds to the main of the mentioned sections, contains two transverse sections parallel to each other on opposite sides and having each direct channel passing between the coupling pipes located on opposite sides of each a transverse section and each section provided with an internal thread, an intermediate partition made continuous and connecting the transverse sections and located perpendicular to them, straight outer ribs extending perpendicularly from two sides of the intermediate partition, and the straight outer ribs are conjugated with intermediate partitions along the middle sections of the inner surface and form the outer surfaces of the front flat surface of the radiator section, two pairs of inner ribs that extend from the intermediate partitions in opposite directions parallel to the straight outer ribs and do not extend beyond the boundaries of the cavities between the facing sections of the straight outer ribs.

The section can be made with a height in the range of 200 - 400 mm.

On Fig - 15 shows the fixing scheme of the sectional radiator of water heating; in Fig.13 and 14 - by known methods, and Fig.15 in accordance with the developed technical solution.

Sectional radiator of water heating (figure 1) contains a set of core 1 and one end 2 section.

The main 1 and end 2 sections each include two transverse sections 3 (Fig. 3, 4) located parallel to opposite sides and having each straight channel 4 extending between the coupling pipes 5 located on opposite sides of each transverse section 3 and having each section 6 with internal thread.

The end section 2 (Fig. 4) contains a longitudinal section 7 connecting the transverse sections 3 and mating with them in their middle zones 8, which has a longitudinal channel 9 communicating from opposite sides 10 with straight channels 4 of the transverse sections 3.

The main 1 and the end 2 sections with through nipples 1 1 (Fig. 1) with external threaded sections 12 are connected in series with each other with an arrangement from one of the edges of the end section 2. Through nipples 1 1 are installed one for each pair of adjacent coupling nozzles 5 two connected sections 1, 2.

Each of the main 1 and end 2 sections contain an intermediate partition 13 (Fig. 3, 4, 5), connecting the transverse sections 3 and located perpendicular to them. In the middle part of the intermediate partition 13 of the end section 2, its longitudinal section 7 passes, and the intermediate partitions 13 of the main sections 1 are solid (Fig. 5).

Direct outer ribs 14 (Fig. 2, 5, 9) extend perpendicularly from two sides from the intermediate partition 13, which are interfaced with the intermediate partitions 13 in the middle sections 15 of the inner surface 16 and form the outer flat surfaces 17 of the front flat surfaces of the radiator sections 1, 2.

Each of the main 1 and end 2 sections include two pairs of inner ribs 18, which extend from the intermediate partition 13 in opposite directions parallel to the straight outer ribs 14 and do not extend beyond the cavities 19 between the facing sections 20 of the straight outer ribs 14, and the inner the ribs 18 are located at equal distances relative to adjacent to them direct outer ribs 14.

Each main section 1 is made of aluminum alloy. It is possible that each main section 1 is made of aluminum alloy with segments of steel pipes (this option is not illustrated in the drawings), cast in aluminum alloy, which form the inner zones of the transverse sections 3.

The end section 2 can also be made of a solid aluminum alloy, similarly to the main section 1. However, it is preferable when the end section 2 is made of aluminum alloy with a frame 21 (Figs. 1, 4) of welded sections of steel pipes forming the inner zones of the conjugate longitudinal 7 and transverse 3 sections.

The sectional radiator of water heating made in the manner described above has a height in the range of 200 - 400 mm, which allows it to be installed on glazed walls and display cases.

To connect, a sectional radiator for water heating contains two plugs and two footers (not shown in the drawings). The plugs are installed in two coupling pipes 5 of the end sections 2, and two futoroks in the coupling pipes of the main section 22 (Figs. 7, 8) located on the radiator side, opposite to the location of the side with the end section 2.

With the help of the foots, the sectional radiator of water heating is connected to the pipes for supplying and discharging the water coolant. In this case, two connection options are possible: the first (Fig. 7) - when the supply pipe is connected to the upper futurka of the main section 22, and the exhaust pipe to the lower futurka of the main section 22; the second (Fig. 8) - when the supply pipe is connected to the lower futurka of the main section 22, and the exhaust pipe is connected to the upper futurka of the main section 22.

For installation on the surface of the base (floor), the sectional radiator of water heating made in the manner described above is provided with at least two supports located at a distance from each other, each of which includes a traverse 23 and a rack 24 with a heel 25 (Fig. 9 - 12) .

The traverse 23 is made in the cross section of a U-shape (Fig. 12) of sheet material with parallel support sections 26 extending from the mating zone having an identical U-shape (Fig. 1) with the legs 24 extending parallel to the axis of the strut 24 from the base 27, corresponding to the specified pairing zone, the extreme sections 28 and the middle section 29 having a lower height than the extreme sections 28.

The extreme sections 28 have a width equal to the distance between the pairs of straight outer ribs 14 and adjacent inner ribs 18 of the main 1 or end 2 sections, and are located relative to each other at a distance corresponding to the distance between the pair of cavities 30 (FIGS. 5, 9) formed between pairs of said adjacent straight outer ribs 14 and inner ribs 18 of each main 1 or end 2 sections.

The middle section 29 of the beam 23 is made with a concave section 31 of the top, which is paired with the outer surface 32 (Fig.9) transverse section 3 of the main 1 or end 2 sections. The supporting sections 26 are located at a distance between each other (Fig), equal to the thickness of the intermediate partition 13.

The traverse 23 is rigidly fixed to the end 33 of the rack 24, on the other end of which is the heel 25 for installation on the supporting flat surface 34 (Fig.9, 10) of the base and for fixing on it.

The rack 24 is made in the form of a rod, and the heel 25 is in the form of a flange with a central hole 35, in which the rack 24 is fixed by the end 36.

In the enlarged portion 37 of the heel 25, mounting holes 38 for attaching the heel 25 parallel to the central hole 35 are provided, arranged eccentrically and evenly around the circumference. To ensure adjustment, the Central hole 35 in the heel 25 is threaded, mating with the threaded section 39 at the end 36 of the rack 24.

The rack 24 is made with an end slot 40 (Fig. 12), in which a cross-arm 23 is fixed, and an intermediate partition 13 of the main 1 and / or end 2 sections passes between the supporting sections 26 of the cross-arm 23 in the zone 41 (Fig. 10) of the location of the slot 40. In this case, the extreme sections 28 are located in the open cavities 30 below between the straight outer ribs 14 and the inner ribs 18, which protrude down further than the lower transverse sections 3, which are also open from the bottom.

The main 1 and end 2 sections are equipped with pairs of parallel additional inner ribs 42 (Figs. 2, 9) located between the transverse sections 3 and extending further located below the transverse sections 3 with the formation of a cavity open at the bottom 43, in which the middle section 29 of the beam 23 is located ( Fig.9), since the distance between the additional inner ribs 42 is equal to the width of the middle section 29.

Traverse 23 is made of aluminum alloy, without interfering with heat transfer, and its extreme sections 28 have a length of not less than a quarter of the height of the main 1 and end sections. A sectional radiator for water heating for installation near glazed walls and display cases can be mounted on brackets 43 (Fig. 13) at the upper and lower transverse sections 3. Brackets 43 are mounted on supporting racks 44, which reduces the overall aesthetics of the structure. It is possible that when the sectional water heating radiator is attached with clamps 45 (Fig. 14) for the lower transverse sections 3, however, such cantilever fixing does not counteract the moment arising from the action of lateral force on the upper part 46 of the sectional heating radiator, which makes such fixing not reliable enough .

The fastening of the sectional radiator of water heating using supports including a traverse 23 and the rack 24 with the heel 25 (Fig. 15) is devoid of the above disadvantages, providing an aesthetic and reliable fastening of the sectional radiator of water heating at the glazed walls and display cases.

The sectional radiator of water heating made in accordance with this technical solution as a whole, its individual main 1 and end 2 sections, supports for installation are made using known technologies corresponding to the materials used, which can be said with respect to other parts of the described construction, for which options specific embodiments are not presented. The exemplary embodiment provided is not exhaustive. There may be other options for implementing a technical solution, corresponding to the volume of patent claims.

The sectional radiator of water heating in accordance with this technical solution has high efficiency at a low height and increased length, since it is connected according to the end circuit and the circulation of the water coolant is carried out along the end section. The main 1 and end 2 sections are made of aluminum alloy with high thermal conductivity. In this case, it is possible to use "bimetallic" technology for the manufacture of both the main 1 and the end 2 sections, but the option when the main sections 1 are made of a solid aluminum alloy is preferable because economic considerations. The sectional radiator of water heating has high aesthetic qualities, the supports on which it is mounted are not visible, and its view from the opposite longitudinal sides is the same. This allows you to install the radiator in the windows and eliminates the need for manufacturing designs for left and right installation. Moreover, the number of sections of the radiator is not limited by anything, and in the case of an extended version, it can be fixed on three or more sequentially installed supports. Supports made as described above resiliently counteract due to the presence of elongated extreme sections 28 to longitudinal horizontal forces, and also effectively resist transverse horizontal forces that can be applied to the sectional water heating radiator mounted on them.
