Description

The invention is a prefabricated concrete interior housing for heating convectors (hereinafter referred to as the concrete housing, product).

The invention relates to elements of heating devices.

The concrete body, consisting of blocks (elements) (item 1), serves to install a heat exchange element into it (item 2), has a protective and load-bearing function, hides the heat exchange element and at the same time is a decorative element of the interior of the room. Further in the text, a block is understood as an element of a concrete body, manufactured entirely (in the form of a non-separable part) for subsequent assembly into a finished product. Further in the text, the heat exchange element refers to water and electric convectors without a housing of various designs.

The material for the manufacture of a concrete body is hydration-hardening composites based on cement (concrete), including those reinforced (fiber or reinforcement) and having various additives, depending on the requirements for the properties and appearance of the material, such as coloring pigments, plasticizers, stabilizers, hardening accelerators, compactors, strength enhancers, rocks and mineral additives (sand, perlite and others). Concrete body blocks are produced by casting into molds or by three-dimensional printing with layer-by-layer application of material (additive technologies).

Currently known are radiators that have a concrete casing, as well as convectors with heat exchange elements that have a metal casing. The closest technical solution (prototype) is a heating device (see patent dated January 24, 1979 No. SU 775537 A1), containing a vertical concrete panel with walled-in heating elements and inclined through slots designed to increase heat transfer. The disadvantages of this design are the low component of convective heat transfer associated with the small surface area of inclined through slots, the large mass and inseparability of the product.

The objective of developing the invention is to solve technical problems:

- high labor intensity in obtaining complex shaped housings for the needs of modern interior solutions associated with the use of casting, cutting, bending, stamping, welding, and metal stripping processes;

- the need and labor intensity of painting the surface of the housings of heating devices;

- the inconvenience of installing and carrying (during delivery) non-dismountable large and heavy heating devices, as well as the technical complexity of manufacturing collapsible heating devices due to possible problems with the tightness of joints;

- inconvenience of servicing non-dismountable heating devices (including internal cleaning).

The technical result is achieved:

- to reduce the labor intensity of producing bodies of complex shapes, through the manufacture (casting or printing) of blocks (elements) of a concrete body entirely (without assembly) with a high-quality surface requiring minimal post-processing;

- to optimize the coloring of products, through the use of coloring in the volume of the material by adding coloring pigments to cement-based solutions;

- to increase the ease of carrying and installation, through the use of a collapsible (block) design of the product;

- to improve ease of maintenance through the use of a collapsible (block) design of the product.

The description of the invention is supplemented by drawings showing:

- Fig. 1 - Visualization of the assembly of a concrete block body and the installation of a heat exchange element (coil with convection plates) in the product (without images of fasteners). General view and isometric drawing of the product;

- Fig. 2 - Visualization of possible options for the appearance and shape of convectors with prefabricated concrete bodies.

The concrete body includes several blocks (elements) (item 1), assembled using fasteners, and also has inlet (in the lower part) and outlet (in the upper part) openings. Inside the concrete body there is a cavity for installing a heat exchange element (item 2). Depending on the design, embedded elements may be provided in the blocks of the concrete body for subsequent assembly into the product.

The prefabricated concrete housing for heating convectors as part of a heating device works as follows:

- for the heat exchange element, a concrete body consisting of blocks (elements) (item 1) performs load-bearing and protective functions;

- a heat exchange element (item 2), installed in a concrete housing, heats the air, the heated air rises naturally (or is forced) and leaves the outlet (in the upper part) of the product;

- a vacuum is created in the concrete body, as a result of which colder air is drawn into the inlet (in the lower part) of the product, due to convection, constant air exchange and heating of the room air is created.
