Description

The utility model relates to heating appliances, in particular, to aluminum and bimetallic radiators with the possibility of connecting inlet and outlet pipes from below.

In modern practice, the installation of heating devices, in addition to the main task of heating the room, seeks to get an aesthetic appearance of all heating elements, increase the safety of operation and provide for the use of individual means to create a comfortable microclimate - temperature-controlled devices. These requirements are met by the lower connection of heating devices, in which it is equipped with a thermostatic valve, and the inlet and outlet pipes are hidden.

Known radiator with a lower connection to the heating system, containing sections with vertical and horizontal pipelines, interconnected with nipples, and a temperature control device (thermostatic valve), which regulates the flow of coolant through the radiator and connected to the radiator through the connecting pipe, while as the connecting pipe used the vertical pipe of the extreme section of the radiator, which is equipped in the upper part with a sealed device with a channel for coolant and stroke seat for the connection of temperature-control systems, and end sections separated from the other sections of the bottom of the radiator blind nipple (RF patent for utility model 74695, publ. 10.07.2008). The pressurized fixture in the upper horizontal pipe and the blind nipple in the lower horizontal pipe are the means of the heat carrier flow distributor.

When implementing this utility model, the number of connections is reduced, and it is enough for the installer to provide the requirements for connecting the radiator to the pipes of the heating system. The radiator, the connection and adjustment elements are a single product, the assembly and verification of which is carried out by the manufacturer, thereby increasing the reliability and durability. The disadvantage of this solution is the technological features of the assembly in terms of installing the device having a channel for the passage of the coolant and a seat for attaching a thermostatic device. It is necessary to ensure high accuracy of the joining of elements and the fastening force, as a result of which the laboriousness of the assembly increases, and as a result, maintainability deteriorates.

Closest to the claimed utility model is a radiator with a lower connection to the heating system, comprising interconnected sections with vertical and horizontal pipelines, an upper flow distributor with a thermostatic valve, equipped with at least one outlet and a lower flow distributor installed in horizontal pipelines of the extreme section of the radiator. The upper flow distributor contains a housing, on one side of which external sealing and stabilizing elements are installed, an adapter is installed on the opposite side, which provides a tight connection of the housing with a thermostatic valve. The casing of the upper flow distributor contains an internal element with a seat for a thermostatic valve, during installation of which a cavity is formed along the inner surface of the casing for the outlet of the coolant. And the inner element has a channel for entering the coolant in communication with at least one inlet made in the housing.

In a radiator in which the sections are connected by means of nipples, the upper flow distributor is installed so that the sealing element abuts against the nipple, and a spring is used as the stabilizing element. In the radiator, in which the sections are connected by welding, a special damper is installed in the upper horizontal pipe of the extreme section, in which the sealing element of the upper flow distributor rests, and a retaining ring is used as a stabilizing element. In one embodiment, the lower flow distributor is a spring valve with a stopper to prevent the coolant from entering the adjacent section. In another embodiment, the lower flow distributor may include a housing, on one side of which an external stabilizing element and a sealing element are installed that tightly covers the end of the housing, and on the opposite side an adapter with an external plug or an external plug is installed. When using the lower flow distributor containing the housing in a radiator in which the sections are connected by nipples, the upper and lower flow distributors are installed so that their sealing elements abut against the nipples, and springs are used as stabilizing elements. In a similar embodiment of the lower distributor in the radiator, in which the sections are connected by welding, special dampers are installed in the upper and lower horizontal pipelines of the extreme section, in which the sealing elements, respectively, of the upper and lower flow distributors abut, and lock rings are used as stabilizing elements (RF patent for utility model 145411, publ. 09/20/2014).

The disadvantage of the prototype device is the low operational reliability, in particular, due to the large number of sealing elements, threaded connections and sealing elements, etc., places of potential leaks, which greatly complicates the manufacturability of the assembly, and at the same time does not provide the necessary tightness of the connection under shock loads bending deformations during installation and transportation.

The technical result achieved by the implementation of the claimed utility model consists in increasing the strength of the radiator, by ensuring tightness, in simplifying the manufacturing technology, assembly and improving manufacturability, reducing material costs for production.

The technical result achieved by the implementation of the proposed utility model is:

- reduction of labor costs when connecting the radiator to the heating system in connection with the use of a minimum number of standard connecting elements and the absence of the need to assemble the radiator itself before carrying out installation work;

- increased reliability due to simplification of the radiator design, the absence of threaded joints and sealing elements in the radiator design;

- reduction of material consumption, and weight of the radiator, as well as a reduction in labor costs in its production in connection with the use of non-metallic bushings as distributors of the coolant flow.

The claimed technical result is achieved in that in the design of the radiator with a lower connection to the heating system, containing row-finned aluminum pipes, the upper and lower manifolds, the upper coolant flow distributor, hermetically connected to the thermostatic valve and the lower coolant flow distributor, installed at the junction of the extreme section of the radiator with the upper lower collectors, in accordance with the claimed solution, the upper flow distributor is made in the form of a cylindrical sleeve, d the line providing tight shutoff of the channel of the outermost section of the radiator that goes into the upper manifold, while, on the diffuser side, the upper distributor has a non-through channel for the coolant that matches the channel of the outermost section of the radiator and connecting the channel of the outermost section of the radiator with the thermostatic valve inlet, and of the opposite side, on the outer surface of the cylindrical sleeve, a longitudinal groove is made connecting the outlet of the thermostatic valve with the upper collector m of radiator, and the lower coolant flow distributor is made in the form of a cylindrical sleeve with a length providing tight shutoff of the channel of the outermost section of the radiator that goes into the lower manifold and has a through channel for the coolant that connects the hole in the lower manifold to supply the coolant with the channel of the extreme section of the radiator.

The utility model is complemented by private distinctive features that contribute to the achievement of the claimed technical result.

The upper distributor is made with a seat for a thermostatic valve.

The recess of the cylindrical sleeve is made with a cross-sectional area equal to the area of the outlet of the thermostatic valve.

The radiator contains row-finned aluminum pipes (instrument sections) 1, forming a diffuser (Fig. 1), as well as upper and lower collectors 2, 3, made of aluminum profile. In the upper collector above the channel of the extreme section of the radiator 4, an upper heat-flux distributor 5 is installed; in the lower collector, under the channel of the extreme section, the lower heat-flux distributor is installed 6. There are two threaded openings 7, 8 for connecting to the coolant inlet and outlet pipelines required to connect the radiator to the standard lower connection unit 9. The radiator is connected to the inlet and outlet pipelines through standard adapters of the bottom connection node 9.

The upper coolant flow distributor 5 is a cylindrical sleeve with an outer diameter equal to the inner diameter of the upper collector (Fig. 2). The length of the upper distributor 5 is made equal to the width of the radiator section and allows hermetically blocking the channel of the extreme section of the radiator 4. The upper distributor 5 is made with a seat 10 for the thermostatic valve 11 having an inlet 12 (Fig. 9). The tightness of the connection of the thermostatic valve 11 and the upper distributor 5 is ensured by sealing rubber gaskets mounted on the thermostatic valve 11. On the diffuser side, the upper distributor 5 has a through channel 13 for the coolant that coincides with the channel of the extreme section of the radiator 4 and the connecting channel of the extreme section of the radiator 4 s seat 10 for thermostatic valve 11. On the opposite side, on the outer surface of the sleeve, the upper distributor 5 has a longitudinal groove 1 4 (Fig. 2), which allows the coolant, from the outlet of the thermostatic valve 15 (Fig. 9) to enter the upper collector of the radiator 2 behind the upper distributor 5. The cross-sectional area of the longitudinal recess 14 is equal to the area of the outlet of the thermostatic valve 11.

The lower coolant flow distributor 6 is a cylindrical sleeve with an outer diameter equal to the inner diameter of the lower manifold 3 (Fig. 5). The length of the lower distributor 6 is made larger than the diameter of the channel of the extreme section of the radiator 4, which allows hermetically blocking the channel of the extreme section of the radiator 4. The lower distributor 6 has a through channel 16 for the coolant connecting the hole in the lower manifold 7, through which the coolant is supplied, with the channel of the extreme section radiator 4. The lower distributor 6 is made with a technological hole 17 from the end connected with the through channel 16.

The lower and upper collectors made of aluminum profile are connected to a row of vertical finned aluminum tubes of the diffuser by means of connecting fittings 18 and 19 having conical and cylindrical parts, hermetically fixed on one side by the conical part of the fitting by means of a press fit in the diffuser pipes, and on the other - a cylindrical part in the holes of the collector.

The radiator with a lower connection with an integrated thermostatic valve can have two versions: left (Fig. 1) and right (Fig. 8). With the right version, the upper and lower distributors 5 and 6 in the radiator manifolds 2 and 3 block the channel of the extreme section 4 on the right, the coolant inlet and outlet are carried out through two adjacent sections located to the right. In the left version, the upper and lower distributors 5 and 6 in the radiator manifolds 2 and 3 block the channel of the extreme section 4 on the left, the input and output of the coolant is carried out through two adjacent sections located on the left.

The radiator works as follows.

The coolant enters through the supply pipe to the lower connection unit 9. The lower flow distributor 6 prevents the coolant from moving along the lower manifold 3 and to other sections and redirects it along the vertical channel of the extreme section 4 to the upper flow distributor 5 (Fig. 1). Through a non-through channel 13 of the upper distributor 5, the coolant enters the seat for the thermostatic valve 10. The entire incoming coolant passes through the inlet 12 of the thermostatic valve 11 (Fig. 1). Then, through the outlet 15 of the thermostatic valve 11, the coolant enters the cavity of the upper manifold 2, between the distributor 5 and the adapter plug 20. Then, through the longitudinal recess 14 of the upper flow distributor 5, the coolant enters the upper manifold 2 and subsequent sections of the radiator and, in the process of circulation , moves to the outlet pipe. Depending on the method of controlling the thermostatic valve 11 (manual or automatic), the thermostatic valve passes the coolant into the radiator at a given either constant or variable flow rate over a period of time. This ensures the necessary heat transfer of the heating radiator to create a comfortable microclimate.

The inventive utility model has the following advantages.

The upper and lower flow distributors are located in the upper and lower collectors of the device during the production of the radiator, which eliminates the need to prepare the radiator before use, reduces the complexity of installation work, increases the reliability of the radiator eliminating unnecessary threaded connections.

Flow distributors are made of non-metallic materials, for example, heat-resistant plastics or plastics. Given that the thermostatic valve is made of alloys (e.g. brass), contact corrosion of dissimilar materials is prevented.

Thus, when using the proposed utility model:

- labor costs are reduced when the radiator is connected to the heating system due to the possibility of using a minimum number of standard fittings and the absence of the need to assemble the radiator itself before installation;

- increases the reliability of the radiator due to the absence of unnecessary threaded connections both when assembling the radiator and when connecting the radiator to the heating system;

- reduced material consumption, and the weight of the radiator, as well as reduced labor costs in its production in connection with the use of non-metallic materials for the manufacture of coolant flow distributors.

The assembly of the radiator with the bottom connection with the built-in thermostatic valve is as follows.

In the process of preparing the radiator for assembly, the bushings for the lower and upper distributors 5 and 6 are separately manufactured. At the end of the sleeve of the upper distributor 6, a seat 10 is made for the thermostatic valve 11, and a recess 14 is also made outside for the heat carrier to pass into the upper radiator collector. A technological hole 17 is made in the end face of the sleeve of the lower distributor to remove the cylindrical roller from the collector cavity after expanding the fitting during the assembly of the radiator. Then the bushings of the upper and lower flow distributors are pressed into the upper and lower radiator headers to the depth of the channel location of the extreme section of the radiator. Next, through holes 7 and 8 are made in the lower radiator header and, at the same time, hole 16 in the lower flow distributor, for connecting to inlet and outlet pipelines. The upper and lower collectors made of an aluminum profile are connected to a row of vertical finned aluminum diffuser pipes by means of connecting fittings having a conical and cylindrical parts, tightly fixed on one side by the conical part of the fitting by means of a press fit in the diffuser pipes, and on the other, by the cylindrical part in manifold holes. The radiator is assembled. As a result of these operations, channels for the coolant appear in the lower and upper flow distributors, which coincide with the channel of the extreme section of the radiator.
