Closest to the proposed are panel radiators Royal Thermo Ventil Compact, selected for the prototype. Known panel radiators are equipped with convection elements, side panels and a top decorative grille. Radiators have six connecting holes, four of which are on the sides of the radiator, and two at the bottom. This makes it possible to connect the radiator to the heating system from below, and if necessary - from the side. The radiator does not have welded brackets and can be mounted with both right and left connections to the heating system. The upper part of the radiator is equipped with a decorative grille. Each bottom-connected radiator has a built-in thermostatic valve (https://www.royal-thermo.ru/catalog/radiatory_otopleniya/panelnye_radiatory/, published 11/26/2018).

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.

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 panel heating radiator of a convector type is claimed, containing heating elements connected to each other, forming the front and rear panels of the radiator, between which a convective element is fixed, distribution tubes for supplying and discharging the coolant, side screens made with the possibility of a removable connection , and an air outlet grille fixed above the heating elements, characterized in that the side screens are equipped with louvered guides, each of which is a lamella bent at an angle to the plane of the side screen with the formation of a slot.

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 elements forming the front and rear panels of the radiator are made of corrugated sheet steel, for example, steel 10, by any known method, for example, stamping, and can be provided with fins. Each 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 equipped with circulation holes at the top and bottom in places intended for welding the 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 pipes 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 from the bottom through the appropriate fittings or nozzles.

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

The side shields are detachably fixed to 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, as a rule, to the front panel or attached to a bracket placed on one of the heating elements by any known method, preferably by threaded connection or by force. friction. Through the air outlet grille, heated air exits the radiator cavity.

In the lower part, the inventive radiator is open, providing entry of a flow of cold air from bottom to top and its passage through the circulation channels in the radiator cavity, contact of the incoming air with heating surfaces and convective elements and exit through the upper air outlet grille and louvre guides placed on 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:

side screens are equipped with horizontal louvre guides;

each of the louvered 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 panels, ensure the movement of the cold incoming air flow 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. 1 schematically shows the principal design of the proposed radiator according to example 1 with two convective elements.

In FIG. 2 shows the design of the side screen of the proposed radiator with louvered guides (the view of the louvered guide in the form of a lamella is shown on the node - “A”), parameters: A, D, E, F, G, J, K, L, M, N, Q, S , T, U, V, W, X are changeable and can take on any values, the number and orientation of the slats can be any.

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 elements,

2 - fittings (distribution tubes for the removal and supply of coolant),

3 - side screens,

4 - upper grille,

5 - convective element,

6 - louver guides,

7 - openings for connection to the heating system.

The inventive panel radiator (Fig. 1) contains two heating elements 1 identical in mirror image, forming the front and rear panels of the radiator. Each of the heating elements 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 coolant channels. In one of the half-panels, circulation holes (not shown) are provided in places for welding of distribution pipes for the removal and supply of heat carrier, made in the form of fittings 2. Convective elements 5 are fixed in the radiator cavity between the heating elements 1, which are corrugated sheets made of sheet steel, ensuring the movement of air flows inside the radiator cavity along the vertical circulation channels between the heating elements 1. The inventive radiator may contain one convective element 5 or more than two convective elements 5. The assembly of the heating element 1 with the formation of the front and rear panels and one or more convective elements 5 is carried out by welding them together by resistance spot welding. The complete assembly of the proposed radiator is carried out by positioning the fittings 2 relative to the heating elements 1 along the circulation holes in the half-panels and subsequent contact welding between the heating elements 1, the convective elements 5 through the fittings 2 to form a coolant circuit. The heating elements 1 are connected to the side screens 3, from above they are equipped with an upper grate 4, which acts as an air outlet grate through which the heated air flow flows from the internal cavity of the radiator vertically upwards into the surrounding space. The lower part of the inventive radiator is made open, i. has an open window formed by the lower edges of the heating elements 1 and the lower edges of the side screens 3, through which cold air enters the circulation channels in the radiator cavity.

On the side screens 3 at the top and bottom there are holes 7 for connecting to the heating system, to which the corresponding ends of the fittings 2 are welded to connect them, for example, with fittings (not shown) to the heating system. The side screens 3 are fixed with hooks (not shown) to the fittings 2, forming a removable connection with the heating elements 1. In the upper part, on the upper edges of the heating elements 1, there is an upper grate 4, which can be fixed, for example, due to the L-shaped hooks available in the upper part of the side screens 3. To increase convection on the side screens 3 between the holes 7 for connection to the heating system, louvre guides 6 are made, representing lamellas bent at an angle to the plane of the side panels 3, made, for example, by stamping, forming in the side screens 3 slots for the directed passage of flows of cold and heated air. Preferably, the slats are made horizontal, while in the lower part of the side screens 3 they are directed downwards, and in the upper part of the slats 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 the fittings 2 into the cavity of the heating panels 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 formed by the lower edges of the heating elements 1 and side screens 3, as well as through louver guides 6 located on the bottom of the side screens 3. The air, passing through the circulation channels formed by the inner surface of the heating elements 1 and the surface of the convective elements 5, which also form tubular circulation channels, contacts with a metal surface heated by the coolant and exits the radiator cavity through the upper grille 4 and through the louvered guides 6 located in the upper part of the side screens 3. Due to the simultaneous presence of the upper grille 4 in the inventive radiator and louvre guides 6, an effective distribution of incoming and outgoing air flows is carried out, the scheme of which is 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 convective elements 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.
