Description

BOXED HEATING RADIATOR Description The utility model relates to the heat engineering industry and can be used in heating systems of individual houses, residential or industrial buildings or any structures with any liquid or gaseous coolant.

There are many designs of radiators. Closest to the utility model that is claimed is a box-shaped heating radiator, described in clause RF N ° 2093759, IPC F24D 3/12, 1997. The well-known box-shaped heating radiator contains a closed box-shaped case with an external heat-exchange surface and additional heat-exchange surfaces. The external heat-exchange surface is formed by the back, directed to the wall of the room, front, directed into the interior of the room, upper, lower and side plates. Additional heat exchange surfaces formed by through tubular elements installed in the body cavity between the back and front plates. In these plates made opposite through holes, which in size and shape coincide with the corresponding ends of the tubular elements. An inlet pipe is installed in the upper part of the casing; an initial pipe is installed in the lower part of the casing. The ends of the tubular elements are connected to the surface of the holes hermetically, thus forming through channels in the radiator body, which combine the air space around the back of the radiator with the air space around the front surface, and are additional heat-exchange surfaces. Due to this, heated air from the surface of the rear plate of the radiator through the through holes of the tubular elements should fall to the front surface and further into the room. But, as a rule, the radiators in the room are installed near the external walls to form a thermal curtain from the cold wall. Through this, the back of the radiator cools faster than the front. Air from the warm surfaces of the tubular elements and the surface of the front plate of the radiator tends to get through the holes to the back of the radiator. Therefore, the effectiveness of such a radiator is small. The utility model is based on the task of improving the box-shaped heating radiator, in which, thanks to the vertical the arrangement of the tubular channels creates conditions for increasing the convective exchange of air layers around and inside the tubular channels of the radiator, thereby increasing the efficiency of the radiator.

The problem is solved as follows. The box-shaped heating radiator comprises a closed box-shaped body with external and additional heat-exchange surfaces. External heat-exchange surfaces consist of a back, directed to the wall of the room, front, directed inland, upper, lower and side plates. Additional heat exchange surfaces formed by through tubular elements located in the case of the casing between two opposite plates. They are installed in appropriate places, where through holes are made in the indicated opposite plates, corresponding to the profile of the tubular elements. The respective ends of the tubular elements are hermetically connected to the surface of the holes. The radiator has an inlet pipe located in the upper part of the casing, and an original pipe located in the lower part of the casing. According to a utility model, these holes are made in the upper and lower plates, and the tubular elements in this case have a vertical direction.

The coolant, moving in the radiator from the inlet to the original, heats up not only the external surfaces, but also the tubular elements located on the path of its flow. The temperature of the upper part of the radiator is higher than the temperature of the lower part of the radiator. In addition, the air under the radiator is colder than above it. Under the influence of thermosiphon traction, which occurs in the cavities of the tubular elements from the temperature difference between the upper and lower parts of the radiator, warm air rises and exits through openings in the upper plate. It is replaced by cold air from under the radiator, which in turn heats up and rises again under the influence of thermosiphon traction. Thus, an additional heating surface is formed, the shape and location of which create conditions for convective exchange of air masses and thus additional heating of the air in the room is carried out.

The predominant is the implementation of a box-shaped heating radiator, in which, according to a utility model, the cross-sectional area of each tubular element is the same in length or evenly increases from the bottom the radiator to its top, the tubular element, in this case, has the shape of any convex figure, for example, a circle, oval or polygon, and each through opposite hole in the upper or lower plates, with the surface of which the end of the tubular element is connected, coincides with the latter in shape and dimensions, the cross section of the outer casing of the radiator may also have any of the following forms.

To increase the surface of the heat sink and improve the conditions of movement of warm air inside the tubular element, on its surface, which is in contact with the air, guide elements are arranged in a spiral. These guide elements can be made of spiral wound wires that are mounted on the specified surface, or in the form of grooves made in a spiral in the surface of the tubular elements. Air that rises along the tubular element under the influence of thermosiphon traction moves with a swirl. Warmer air molecules move closer to the center of the tubular element, colder ones move in a vortex along the periphery of the tubular element and heat up, sliding along its surface.

The box-shaped heating radiator mainly comprises a heat shield mounted on the rear plate of the radiator. The heat shield can be made of heat-insulating material or sheet metal, with heat-insulating material applied to it. So, the heat-insulating screen can be made, for example, of aluminum foil. The box-shaped heating radiator mainly has a cover on its upper plate of the housing with holes made therein and guiding protrusions located above the holes directed at an acute angle from the back of the radiator to the front.

The structural implementation of the claimed utility model is illustrated by drawings, where Fig. 1 schematically shows a general view of a box-shaped heating radiator in a perspective view with the top cover removed. Figure 2 shows a view of the radiator in the direction of arrow A with a screen and a top cover. On fir.Z the image of the concept of water heating. The drawing, as well as the following example of a specific implementation of the utility model, which is claimed, only explain its essence, without limiting the scope of rights defined by the formula. The heating radiator 1, which is claimed, contains a closed box-shaped housing 2 with a back plate 3, which, when installed in a room, is directed towards the wall, with a face plate 4, which, when installed in a room, is directed into the interior of the room, with side plates 5 and 6, upper 7, and lower 8 plates. The plates form the external heat exchange surfaces of the radiator. In plates 7 and 8 formed through, mainly coaxial holes. Inside the housing 2, in the places where the holes were made, tubular elements 9 are installed. The tubular elements 9 of the radiator shown in FIG. 1, made of a pipe of circular cross section with the same inner and outer diameters along the length of the pipe. The diameter of the holes in the plates 7 and 8 is the same as the outer diameter of the tubular element 9. The corresponding ends of the tubular elements 9 are inserted into the holes and hermetically welded with opposite plates of the housing on the outer surface of the plate or on the inside. The tightness of the housing 2 is not affected, i.e. the coolant in the radiator circulates without leakage. And the internal cavities of the tubular elements, in this case, form additional heat-exchange surfaces. To increase the heat transfer surface and improve heat dissipation through the tubular elements 9, there are spiral elements of the guide elements 10. The guide elements of the radiator shown in FIG. 1, made of a spiral wound wire, the ends of which are fixed to the ends of the tubular element. The radiator also contains an inlet pipe 11, installed in the upper part of the housing 1, and the source pipe 12, located in the lower part of the housing 1. The inlet and source pipes of the radiator are connected to the water heating system with natural circulation of the coolant. The radiator, which is claimed, can also work well in water heating systems with forced circulation, but its effectiveness is sufficient for use in systems with natural circulation, which is a great advantage compared to other existing designs of radiators. To reduce the cost of heat for heating the external walls of the room and directing the entire heat flux from the radiator to heating the air in the room, the radiator contains a heat shield 13 installed behind its back plate and mounted on it. The heat shield is made of aluminum foil and is located on a distance of 2-5 cm from the rear plate of the radiator. On the upper plate 7 of the radiator case, a mounted cover 14 with holes 15 partially stamped on it and bent guide protrusions 16 located above the holes at an angle and directed deep into the room. The radiator 1 is combined with a gas generator (or boiler) 17 by an underwater pipe 18. An outlet pipe 19 is installed in the system for discharging chilled water to the expansion vessel 20 combined with the gas generator.

The radiator works in the heating system in this way (Fig. 4). The density of chilled water is greater than the density of heated water. The heating system is a closed system, and the water in it circulates, rising up in the heated state and dropping down in the cooled, to balance the weight of the columns of heated and cooled water under the influence of hydrostatic pressure, which occurs due to the different density of the cooled and heated water. Heated water from the gas generator 17 under the pressure of a column of cold water, which presses on it from above, from the expanding vessel 20 through pipes 18 enters the radiator 1 through the inlet pipe 11 and displaces from the lower cooled part of the radiator through the source pipe 12. On the way, the water partially gives off heat through the surface of the upper parts of the radiator and cooling, falls down. The plates transfer heat to the air that surrounds the radiator from the outside. The air in the tubular elements 9 is also heated. The warm air inside the element 9, also having a lower density than the cold one, rises up and comes to the surface above the top plate 7. In its place, cooler air comes from under the bottom plate of the radiator. The guide elements 10 intensify the air draft, causing the air flows to move in a spiral and thereby intensify the heat transfer. Under the influence of thermosiphon traction, air circulates all the time, reducing the temperature difference between the air near the floor and the air above the radiator. The installation of the cover 14 with holes 15 and the guiding projections 16 facilitates the flow of air into the room and its intensive heat transfer. A heat shield 13 on the back of the radiator protects the heat from being taken in by the outer wall of the room. Thermal masses, fighting off the heat shield, are sent to the area above the top plate of the radiator. The heat transfer of the radiator, due to the presence of these elements in the radiator, is much higher compared to existing samples. OPTION OF TECHNOLOGICAL MANUFACTURE OF A BOXED RADIATOR BY CREATION OF SECTIONS FROM PIPES WITH A DIAMETER OF 50 AND 100 mm.

Of the various solutions for the technological implementation of the box-shaped radiator, I consider it expedient to create it from pipes with a diameter of 50 mm 21 and 100 mm 22 by filling the ends of the pipe 100 mm 23 and expanding the ends of the pipe 50 mm FIG. 7), and welding them together at the junction (Fig. 6). Thus, a hermetically closed space is created between the pipes for the passage of the coolant. Between themselves and the heating system, such sections (Fig. 8) are connected using standard shrink couplings and plugs, which are used in cast iron batteries, for which purpose in an outer pipe with a diameter of 100 mm. in the upper and lower parts, two coaxial holes 24 with threaded threads for standard couplings and plugs 25 are cut and rolled into the middle in the middle (Fig. 9). A possible simplified connection of the radiator sections by welding together, instead of connecting with couplings, for which the holes in the outer pipe are flared outward and welded with the holes of the next section strictly parallel and coaxial. Thus, a radiator with the desired number of sections is dialed (Fig. 4). Schematic drawings and schematic drawings are attached (Fig. 5-9).
