When analyzing the prior art, the following sources of information related to the device of the same purpose were also taken into account - RU 210249, SU 965668, RU 48397, UA 0000039452.

The disadvantages of the known panel radiators include insufficiently high heat transfer efficiency due to insufficient turbulence of coolant flows, insufficiently efficient air exchange inside the radiator and at its outlet, because the outlet of the heated air flow is carried out only through the grille in the upper part of the radiator. In addition, all known panel heating radiators contain front and rear heating panels that form the front and rear heating sections of the radiator, which significantly increases the material consumption of the radiator.

Closest to the proposed are panel radiators Royal Thermo COMPACT C11, selected for the prototype. Known panel radiators are equipped with one heating panel, one convection element, box-type side panels and a top decorative grille. For mounting, the radiators have 4 connecting holes with a diameter of 1/2 on the sides of the radiator. The radiator can be connected to the heating system both on the right and on the left side. Each radiator with bottom connection has a built-in thermostatic valve. (https://www.royal-thermo.ru/catalog/radiatory_otopleniya/panelnye_radiatory/compact/#fo, published on 12/18/2018)

Known radiator has a reduced material consumption, but has insufficiently high heat transfer efficiency due to insufficient turbulence of the coolant flows, insufficiently efficient air exchange inside the radiator and at the outlet from it, tk. the outlet of the heated air flow is carried out only through the grille in the upper part of the radiator.

The objective of the claimed utility model is to increase the efficiency of a panel radiator with a convective element by providing the possibility of creating an additional heat flow of air that increases the integral heat flow of the radiator.

The problem is solved by the fact that a convector-type panel heating radiator is claimed, containing a heating and convective elements connected to each other, forming the front and rear panels of the radiator, the heating element is connected to distribution pipes for supplying and discharging the coolant, the heating and convective elements are equipped with side screens, made with the possibility of removable connection and equipped with holes for distribution tubes, and an air outlet grille located on top, characterized in that, on the side screens between the holes for the distribution tubes, louvered guides are made, each of which is a lamella bent at an angle to the plane of the side screen with the formation of a gap.

Louvre guides can be represented by horizontal or vertical slats with the formation of horizontally or vertically arranged slots, respectively. The lamellas serve as guides for the incoming flow of cold air and the flow of heated air leaving the radiator. The direction of the slats is chosen in such a way as to ensure the movement of incoming and outgoing air flows through the slots from bottom to top. The angle formed by the lamella and the plane of the side screen is calculated based on their technical parameters of the radiator. The slats can be made multidirectional in the lower and upper parts of the side screens, i.e. in the lower part of the side screens, the horizontal lamellas can be directed downwards (the rays of the angle formed by them are directed downwards), and in the upper part of the side screens, the lamellas can be directed upwards. The slats in the lower and upper parts of the side screens can be directed upwards, i.e. can be made unidirectional. The direction of the slats and the angle of their inclination is selected based on the need to ensure the directed movement of air flows. In the lower part of the side screens, the movement of the air flow entering from the outside is carried out from the bottom upwards into the radiator cavity formed by the connection of the heating front and rear panels of the radiator to each other. In the upper part of the side screens, the flow of heated air leaving the radiator cavity is directed from bottom to top.

On the side screens, lamellas can be formed, for example, by stamping or punching a part of a metal sheet and bending it at an angle to the plane of the side screen, forming a slot for the passage of air flows, while the lamellas act as air flow guides.

The heating element forming the front panel of the radiator is made of corrugated sheet steel, for example, steel 10, by any known method, for example, stamping, and can be provided with fins. The heating element is made of two half-panels, essentially representing plates that are rigidly connected to each other along the perimeter by welding to form a cavity for the passage of the coolant supplied from the heating system through the circulation channels, and are provided with circulation holes at the top and bottom in places intended for welding ends of the distribution pipes for supplying and discharging the coolant, made, for example, in the form of fittings.

The convective element is represented by one corrugated sheet or two corrugated sheets made of sheet steel by any known method, for example, by stamping. The corrugation of the convective elements ensures the presence of vertical grooves, which act as vertical circulation channels for the passage of air flows, and also ensures efficient heat transfer due to the developed heat exchange surface.

Distribution tubes for supplying and discharging heat carrier are fittings that can be made of steel, stainless steel, etc. by any known methods and placed horizontally and vertically, have inlets / outlets for connecting to the heating system from the side and / or from below by means of appropriate fittings or pipes.

The side screens are made of sheet steel and are provided with holes made, for example, by punching or cutting or stamping, for connecting the heating element to the pipes of the heating system through distribution pipes for supplying and discharging heat carrier. The connection of the radiator to the pipes of the heating system can be carried out by connecting elements, for example, fittings, branch pipes.

The side shields are detachably attached to the heatsink, making contact with the vertical edges of the front and rear panels to allow assembly, disassembly, inspection and, if necessary, repair work.

In the upper part, the inventive radiator is equipped with an air outlet grille, which can be detachably fixed directly to the upper horizontal edge of the heating element or attached to a bracket placed on the heating element by any known method, preferably by a threaded connection or can be fixed with L-shaped hooks made on the side panels. . Through the air outlet grille, heated air exits the radiator cavity.

In the lower part of the inventive radiator is open, providing the entry of a flow of cold air from the bottom-up and passing it through the vertical circulation channels in the cavity of the radiator, formed by the corrugated parts of the heating panel and the convective element. The flow of cold air also enters through the lower louvre guides located on the side screens. The incoming air is in contact with the heating surface and the convective element. The exit of heated air is carried out through the upper air outlet grille and louvre guides located in the upper part of the side screens.

Any medium can be used as a heat carrier - water, gas (air), oil.

The inventive radiator is additionally equipped with any known built-in thermostatic valve.

Comparison of the proposed convector-type panel heating radiator with the prototype makes it possible to identify the following distinguishing features:

louvered guides are made on the side screens between the holes for the distribution tubes;

each of the louvre guides is a lamella, bent at an angle to the plane of the side panel with the formation of a slot.

The presence of distinctive features allows us to conclude that the proposed panel heating radiator complies with the "novelty" condition.

The inventive radiator can be made from known materials, by known methods, by assembly by known methods, i.e. meets the condition of "industrial applicability".

The presence of louvered guides on the side screens, the lamellas of which are preferably horizontal and differently directed in the upper and lower parts of the screens, ensure the movement of the flow of cold incoming air from the bottom up, the passage of the air flow through the radiator cavity, heating and the exit of the heated air flow from the bottom up, i.e. allow to increase the efficiency of heat exchange by creating an additional heat flow of air from the side screens, increasing the integral heat flow from the heater. This effect is achieved due to the mixing of internal and external convective flows, which leads to an increase in the flow rate of air moving due to the difference in densities inside the panel radiator, intensification of heat transfer in the internal space of the radiator due to additional turbulence of the convective flow, an increase in the temperature difference between the air moving inside the radiator and convective surfaces (mass-average air temperature and average surface temperature of the radiator); slight increase in heat transfer surface area.

The inventive panel radiators can be made of steel or bimetal with side connection. The inventive radiators can be made with a bottom connection to the heating system and have two versions: left and right.

The claimed utility model is illustrated by examples of a specific implementation, but is not limited to them.

In FIG. 3 schematically shows the distribution of flows of incoming and outgoing air through the louver guides and the scheme of movement of the convection air flow inside the radiator cavity

In FIG. 4 shows a general view of the claimed radiator assembly.

The following designations are used in the figures:

1 - heating element,

2 - fittings (distribution tubes for supplying and discharging coolant),

3 - side screens,

4 - upper grille,

5 - convective element,

6 - blind guides,

7 - openings for connection to the heating system.

The inventive panel radiator (Fig. 1) contains a heating element 1, which forms the front panel of the radiator. The heating element 1 is a welded sealed structure (Fig. 1, Fig. 4), consisting of two stamped half-panels made of corrugated steel sheets and welded together by spot and disk welding, resulting in a panel with a cavity having circulation channels for the coolant . In one of the half-panels, circulation holes (not shown) are provided in places for welding distribution pipes for the removal and supply of heat carrier, made in the form of fittings 2. The radiator is equipped with a convective element 5, which is a corrugated sheet made of sheet steel, ensuring the movement of air flows inside the radiator cavity through vertical circulation channels. The heating element 1 and the convective element 5 are rigidly connected to each other to form a radiator cavity. The inventive radiator may contain one convective element 5 or more than two convective elements 5. Assembly of the heating element 1 and one or more convective elements 5 is carried out by welding them together by resistance spot welding. The complete assembly of the inventive radiator is carried out by positioning the distribution tubes for supplying and discharging the coolant, made in the form of fittings 2, relative to the heating element 1 along the circulation holes in the half-panels and subsequent resistance welding of the heating element 1, the convective element 5 through fittings 2 to form a coolant circuit. The heating element 1 and the convective element 5 are equipped with side screens 3 and an upper grate 4, which acts as an air outlet grate through which the flow of heated air flows vertically upwards from the internal cavity of the radiator into the surrounding space. Side screens 3 are put on the ends of the fittings 2 placed in the holes 7 for connection to the heating system, forming a removable connection. The corresponding ends of the fittings 2 are welded to the holes 7 and connected to the heating system, for example, fittings (not shown).

The lower part of the inventive radiator is made open, i. has an open window formed by the lower edges of the heating element 1, the convective element 5 and the lower edges of the side screens 3, through which cold air enters the circulation channels in the radiator cavity.

In the upper part there is an upper grate 4, which can be fixed, for example, due to L-shaped hooks in the upper part of the side screens 3. lamellas bent at an angle to the plane of the side panels 3, made, for example, by stamping, forming slots in the side screens 3 for the directed passage of flows of cold and heated air. Preferably, the lamellas are made horizontal, while in the lower part of the side screens 3 they are directed downwards, and in the upper part of the lamellas are directed upwards.

The inventive panel radiator works as follows.

In FIG. 1 shows a panel radiator, which is connected by means of fittings 2 to the pipes of the heating system for supplying a heat carrier, which is water. The coolant enters the radiator through fittings 2 into the cavity of the heating panel 1, where it circulates through the tubular circulation channels formed by the corrugated part of the half-panels. The air from the room enters the radiator from below through an open window in the lower part of the radiator and louvre guides 6 located on the bottom side screens 3. The air, passing through the circulation channels formed by the inner surface of the heating element 1 and the surface of the convective element 5, comes into contact with the metal heated by the coolant surface and exits the radiator cavity through the upper grille 4 and through the louvre guides 6 located in the upper part of the side screens 3. shown in FIG. 3.

The presence of louvered guides on the side screens ensures that cold air is drawn through the slots due to a local decrease in pressure in the radiator cavity when the internal flow is disrupted (ejection effect), i.e. the air flow inside the convective elements rises due to heating, accelerates a little, flows around the louvre guides, the pressure drops (due to the narrowing of the channel) and the outside air is drawn into the radiator. Air mixing is carried out due to the fact that the outside air is drawn into the slots of the louvre guides and mixed with the internal air of the radiator, giving turbulence, and squeezed out through the slots of the louvre guides located in the upper part of the side screens. Pulling in cold air and expelling hot air through the side screens increases the efficiency of the radiator by increasing the convection of the passing air stream, which results in more active mixing of the air stream.

The inventive panel radiator with a convective element makes it possible to increase the efficiency of the panel radiator by providing the possibility of creating an additional heat flow of air through the side screens, which increases the integral heat flow of the radiator.
