Description

This technical solution relates to convector-type room heaters, in particular to casings of such heaters, which are installed mainly on the floor of the heated room and, as a result, have significant distinguishing features, characterized by the presence in the casing of supports for installing the casing and the heater as a whole on the specified floor.

Known casings of floor heating convectors, each of which includes front, rear, side and upper walls, with air outlets in the upper wall, and the lower part of the casing having supports for installing the casing on the floor of a heated room [1-14].

Convector casings [1, 2, 7, 12, 14 and 15] have panels from which the front or rear walls of the casings are made, and casings [3, 4, 5, 7, 9, 10, 11] have removable upper parts, which include the upper wall with air outlets in it.

Known casings are intended primarily for their use in medium power convectors.

However, with a significant increase in the power of convectors and, accordingly, the dimensions of heat exchangers for powerful convectors, the dimensions of the casings increase significantly, as a result of which the known

casing designs cannot be used for high power convectors with a nominal heat flux, for example, from 4 to 16 kW.

The solved problem of this technical solution is to create a unified casing for floor heating convectors of high power.

This problem is solved in that in the casing of the floor heating convector, containing the upper part with the upper wall, front, rear and side walls that are interconnected and form a three-dimensional rigid metal structure with an air cavity under the heat exchanger, while the casing is made with supports, air intake in the lower part and air outlets in the upper wall, - the upper wall in its cross section has a U-shape and attached to it side elements that cover its end sides, which are from the upper form a wall with a volumetric trough-like structure connected to the side, front and rear walls, the front and rear walls made of separate longitudinally arranged panels interconnected by the side walls and the upper part of the casing, the height of each side wall is greater than the height of the front and rear walls, between the lower edges of the front and rear walls and the floor of the heated room are openings for air intake.

Flanges are made on the lower side of the upper part of the casing, connected with flanges of the side, front and rear walls, flanges of the upper part of the casing are located on the opposite side from the air outlets, the latter are formed by notches and trapezoidal inclined flanges bent into the casing made in the middle of the upper wall.

The upper wall is made rectilinear and each end face is joined with a protrusion made on a side element of the upper part of the casing so that the upper surfaces of the upper wall and side elements are located in the same plane.

The casing of the floor heating convector (Fig. 1) contains a front wall 1, side walls 2, a rear wall 3 (Fig. 2) and an upper wall 4, while all these walls are fastened together by joints in such a way that they form a bulk metal structure with an air cavity 5. The cavity 5 performs the functions of the duct. This cavity is also intended for placement of a heat exchanger (not shown) in it, which is installed between the floor 6 of the heated room and the air outlet 7 of the upper wall 4. Between the floor 6 and the lower edges of the front and rear walls 1 and 3 of the casing, an air intake of the casing or openings 8 ( figure 3).

The casing has two side supports 9 (figure 1) for its support on the floor 6 of the heated room. The supports 9 are formed by the side walls 2 in the lower part of the casing. The casing has additional supports 10 located inside the casing between the supports 9 or the side walls 2. To these supports 10, if necessary, extension cords 10 or support elements (not shown) are designed to further support the casing on the floor of the heated room in order to evenly distribute the load on the floor due to the large weight of the heat exchanger, as well as for the purpose of attaching the casing to the floor.

The casing is made of separate interconnected upper part 11, lower part 12 and at least one middle part 13. All parts of the casing are interconnected so that the adjacent elements of these parts of the casing form the aforementioned casing walls. These parts of the casing include flanging 14 (figure 2), which are fastened to the casing elements with rivets 15 or other similar compounds. Flanges 14 are located inside the casing.

The upper part 11 of the casing is made voluminous, trough-like with rounded upper corners, the open side faces the side, front and rear walls of the casing. The upper part 11 of the casing includes the upper wall 4 of the casing (Fig. 13), having a U-shaped cross-section (Fig. 15) with rounded upper corners, as well as volumetric side elements 16 (Figs. 17-19) connected to the upper wall 4. The side elements face the inside of the casing with the open sides 17 (Fig. 11), docked to the side ends of the upper wall 4 and connected to them so that their upper surfaces are in the plane of the upper wall 4, and their sides are in the plane of the side walls 2 casing (figure 10). The upper part 11 of the casing has flanges 18 located inside it (FIGS. 2, 4) connected to the flanges 14 of the middle part 13 of the casing.

The air outlets 7 (FIG. 13) of the upper wall 4 are formed by trapezoidal inclined flanges 19 directed into the casing, made in the middle part of the upper wall 4 by forming a plurality of notches in the upper wall 4, in its middle part, and by bending the inclined flanges 19 towards the air cavity 5 of the casing. The upper wall 4 is made rectilinear and its aforementioned ends or short sides 20 (Fig. 11) are joined flush with the protrusion 21 of the side elements 16. The upper surface 22 of the upper wall 4 and the upper surfaces 23 of the side elements 16 are located in the same plane.

The front and rear walls 1 and 3 (Fig. 4) are made of separate panels 24, 25 and 26 connected to each other and to the side walls 2, which are identical in shape or may be identical. These panels are connected by flanges 14 located inside the casing.

The lower part 13 of the casing is also formed of separate interconnected panels 27, 28 and 29, which are interconnected and the side walls in a similar way.

Flanges 18 (figure 4) of the upper part 11 of the casing are connected with flanges 14 of the middle part 13 of the casing with screws 30. Such flanges can also connect flanges 14 of the middle part 13 of the casing with flanges 14 of the lower part 12 of the casing. In the side walls 2 of the casing (Fig. 2), holes 31 are made for the air damper handles (not shown), which is designed to adjust the air flow in the air cavity 5 of the casing during the operation of the convector and in the process of heat exchange between the heat exchanger and the air flow passing through the casing . Position 32 (figure 1) shows the tears of the casing.

There are several options for the implementation of large-sized casings for convectors of various high power, mainly for industrial use. In the description are given three options for the casing, differing among themselves by the different number of available in it

middle parts or the number of panels of the front and rear walls of the casing and the height of the side walls.

The first variant of the casing (Fig. 1) contains its upper part 11 and the lower part 12. The second variant of the casing (Fig. 4) contains the upper part 11, the lower part 12 and the middle part 13. The third variant of the casing (Fig. 3) contains the upper part 11, the lower part 12 and the two middle parts 13.

All options differ from each other in the number of panels of the front and rear walls and the height of the side walls, while the design of the removable upper part of the casing remains unchanged for all casing options, which makes it possible to manufacture various large-sized casings from a high degree of unified elements.

There is a method of assembling a casing, which includes the operation of connecting the lower, middle and upper parts of the casing (Fig.6) to each other, while all these parts of the casing are formed by connecting with the side walls 2 of the panels 24-29 (Fig.4) of the front and rear walls , while the panels are also interconnected. Next, the upper part 11 of the casing is installed on the assembly table down by the air outlet openings 7, for which, as shown in Fig. 11, the upper part 11 of the casing is turned 180 degrees around its horizontal axis. Then, the casing shown in Fig. 4 is turned over (without the upper part 11) 180 degrees around its horizontal axis, the seats of the middle part 13 of the casing are combined with the seats of the upper part 11 of the casing, for which flanges 14 and 18 are joined and the holes made in them are aligned into which screws 30 are inserted and then screws 30 firmly connect the flanges 14 and 18 to each other and thus connect the upper part 11 of the casing to its adjacent part.

Such operations are performed in order to provide access to the screws 30 during the assembly of a high-height casing. The screws 30 are accessed from above through the air cavity 5 of the lower part 12 of the casing, which is inverted for the duration of the assembly.

The casing works as follows. A heat exchanger is installed in the casing, through which the coolant is passed. Air in

the air cavity 5 (figure 2) is heated by a heat exchanger and exits through the air outlet 7 into a heated room. When this cold air through the air intake or through the openings 8 of the casing enters the air cavity 5 of the casing. Due to the temperature difference in the lower and upper parts of the casing, an air draft is created in the air cavity 5, which is regulated by turning the air damper (not shown) installed in the handles (not shown) mounted in the holes 31 (figure 2) of the side walls 2 of the casing .
