Description

The utility model relates to the field of heating and is designed to be installed on a hot water supply pipe to ensure heat exchange between environments with different temperatures.

A removable heat exchanger is known from RF patent No. 197709 for a utility model, containing a tubular metal clamp, consisting of semi-cylindrical linings made to cover the coolant pipe, heat transfer fins are installed on the linings perpendicular to their longitudinal axes, while the fins are located on the linings in a mirror image with the same pitch between adjacent fins, and the pairs of mirror fins form rectangles with beveled opposite sides, the surface area of the linings with heat transfer fins is at least four times greater than the outer surface of the coolant pipe at the installation site.

The disadvantage of this device is that its technical capabilities are limited to use only in order to increase the efficiency of heat transfer from the coolant pipe.

From the patent of the Russian Federation No. 2353882 for the invention, a heat radiator for heating or cooling is known, made in the form of a heat-conducting metal structure with fins to increase the heat transfer surface and containing elements for fastening on pipelines with a liquid or gaseous heat carrier, characterized in that it is made in the form of a removable metal clamp containing curved adjustable pads on the pipeline with heat transfer fins and their tightening elements for tightly wrapping the pipeline in the installation area, and the bases of the pads in contact with the pipeline are made with a C-shaped channel in the shape of the pipeline section, the clamp is made with a longitudinal length of at least four and with a width of at least two pipeline diameters, the outer surface area of the lining with ribs is at least twice the outer surface of the pipeline at the installation site, while each clamp contains at least 3 main heat transfer ribs, including ribs for tightening and fastening collar linings along the length of the pipeline, the main ribs are made integrally with their part of the liner base, and the coverage sector of each C-shaped channel does not exceed 175 °. One of the variants of the specified invention is characterized in that at least one patch is made in the form of a hollow thin-walled sealed tubular shell for filling it with a liquid heat carrier such as water.

The disadvantage of this invention is also the limitation of its functionality, allowing the device to be used only in order to increase the heat transfer of the coolant pipes.

The invention under the RF patent No. 2353882 was selected as the closest analogue.

The technical problem solved by the proposed utility model is the provision of indirect heat exchange, which increases the reliability of the heating pipe (heated towel rail, underfloor heating and other equipment that requires heating and is located remotely from the hot water supply pipe), by isolating the inner cavity of the heating pipe from the inner cavity of the hot pipe. water supply and at the same time reducing the number of plumbing connections operating under high pressure and thereby creating an emergency situation.

The technical result of the utility model is the expansion of functionality, which makes it possible to use a heated towel rail, equipment in the form of a warm floor and other equipment that requires heating and is located remotely from the hot water supply pipe as a heating pipe, the internal cavity of which is connected to the adapter.

The claimed technical result is achieved due to the fact that an overhead heat exchanger containing an adapter designed to cover the hot water supply pipe and a heating pipe, the internal cavities of the adapter and the heating pipes are designed to be filled with a liquid heat carrier, according to the utility model, the internal cavity of the adapter is connected with the internal cavity of the pipe heating by means of non-heat-conducting connecting pipes through the inlet and outlet pipes of the heating pipe with the possibility of circulating the liquid heat carrier, while the walls of the adapter and the heating pipe are made heat-conducting.

The connecting pipes can be flexible.

Water is the liquid heat carrier.

The heating pipe can be installed vertically.

The inner cavity of the adapter communicates with the inner cavity of the heating pipe, installed vertically, by means of connecting pipes through the upper supply pipe and the lower outlet pipe of the heating pipe.

The heating pipe can be made in the form of a heated towel rail.

The heating pipe can be made in the form of a warm floor.

The circulation of the heat transfer fluid can be ensured by means of a pump installed in the connecting pipe.

The claimed device contains an adapter and a heating pipe, which can be used as any device, the heating of which must be provided. The condition for heating the heating pipe is the communication of its inner cavity with the inner cavity of the adapter, while in the inner cavity of both elements there is a liquid heat carrier, for example, water. A condition for expanding the types of heating pipes used in the claimed device (heated towel rail, warm floor, warm walls, etc.) is the connection of the heating pipe with the adapter by means of connecting pipes. The choice of the length of the connecting pipes is determined by the distance from the heating pipe to the adapter. The connecting pipes must be insulated (non-thermally conductive) and, if possible, flexible.

The implementation of the connecting pipes non-heat-conducting (insulated) can significantly reduce heat loss during the movement of the liquid heat carrier from the adapter in the heating pipe.

Making the connecting pipes flexible allows them to be laid in an optimal way, depending on the design of the heating pipe and on the geometry of the room where the proposed device is supposed to be installed.

The adapter is made with the possibility of full or partial coverage of the hot water supply pipe.

To ensure indirect heat exchange, the walls of the adapter and the heating pipe are made of heat-conducting material (for example, copper, aluminum, etc.).

The adapter is made by casting, stamping, welding, soldering, etc. both ferrous and non-ferrous metal.

The coverage area of the hot water supply pipe with the adapter depends on the material from which the hot water supply pipe is made.

If the hot water supply pipe is made of polymer, then the coverage area of the adapter is provided along the entire diameter of the pipe. If the hot water supply pipe is metal, then the coverage area of the adapter can be smaller and is provided with partial coverage along the radius of the pipe.

The walls of the adapter are made with a cavity, which is isolated from the cavity of the hot water supply pipe, but has thermal contact with it through the inner wall of the adapter, which allows heating the heat transfer fluid and the heating pipe by circulating the heat transfer fluid inside the surface-mounted heat exchanger.

The temperature range of heating the liquid heat carrier and the heating pipe is determined by the degree of heating of the hot water supply pipe.

In the process of circulation of the liquid heat carrier, the loss of its heat during its movement from the adapter to the heating pipe is no more than 10%.

The heating pipe can be placed both vertically (for example, in the form of a heated towel rail, a warm wall) and horizontally (for example, in the form of a warm floor).

The circulation of the heat transfer fluid in the surface-mounted heat exchanger can be both natural and artificial (forced), depending on the location of the heating pipe and the heating area.

Natural circulation is possible if a vertical heating pipe is used as a heating pipe, for example, a heated towel rail located vertically relative to the adapter. In this case, water from the adapter must be supplied to the heating pipe through the connecting pipe through the upper inlet pipe of the heating pipe, and it must be discharged through the lower outlet pipe of the heating pipe. With this arrangement of the heating pipe and the supply / removal of the liquid heat carrier, natural circulation will occur - the water from the upper supply pipe will cool down and fall to the lower outlet pipe, from which the water enters the adapter through the connecting pipe, heats up again, etc.

Forced circulation is provided by means of a pump, which is installed in the connecting pipe.

The internal cavities of the adapter, connecting pipes and heating pipes are completely filled with a liquid coolant, otherwise (with incomplete filling), circulation of the coolant in the claimed device will either not occur (in the absence of pumps), or it will be significantly hampered.

The claimed device is reliable. The reliability of the device is increased by isolating the inner cavity of the heating pipe from the inner cavity of the hot water supply pipe and reducing the number of plumbing connections operating under high pressure and thereby creating an emergency situation.

In addition, the claimed device makes it possible to use a heated towel rail, equipment in the form of a warm floor and other equipment that requires heating and is located remotely from the hot water supply pipe as a heating pipe, the internal cavity of which is connected to the adapter. Thus, the expansion of the functionality of the claimed device is provided.
