Description

Heating convector

The utility model relates to general purpose structural elements for heat exchange and heat transfer devices, in particular, to a heating convector, and can be used in heating systems of buildings for various purposes.

A known heating device for central heating systems (RF patent No. 2092747, class IPC F 24 H 3/06, published in 1997), consisting of sections with tubular elements for a coolant, fins and holes for interconnection, the sections are equipped internal radial and external contours of fins with bilateral upper, lower and longitudinal holes. At the junction of the sections, gasket-rippers of the coolant flow are installed, and the tubular elements of the extreme sections are connected by a pipe.

However, in this design there is no uniform heating of all elements due to the formation of an air bubble in the upper tubular element.

The closest in the set of essential features to the claimed utility model is a convector (patent of RB No. 488 for the industrial design “Convector (two options), class MKPO 23-03, published in 2002), consisting of sections of fins, pressed onto one horizontal pipe or two pipes. In a two-pipe convector, two

pipes along the coolant supply are connected by a pipe.

However, this device has the same drawback as the previous analogue.

The task to which the claimed utility model is directed is to increase the heat transfer of the convector in comparison with existing devices of this type, as well as to increase the corrosion resistance of the internal surfaces of the heat transfer pipes.

Obtaining a technical result is achieved by the fact that in the heating convector, containing at least one horizontal heat transfer pipe, while designed to supply a heat transfer fluid, with fins mounted on it, a valve is located in the upper part of the heat transfer pipe to remove air.

In addition, in the convector, a heating tap for removing air can be located at one of the end sections of the heat transfer pipe.

In addition to this, the fins are aluminum cast structures consisting of at least one cylindrical base, a ribbed panel extending vertically through its center through its middle, the ribs being symmetrical and perpendicular to the panel, and the two extreme ribs forming the front and back heat exchange surfaces .

2 The convector may also contain two heat exchange tubes for

liquid coolant supply, connected by a pipe, while the valve for removing air will be in the upper pipe.

In addition, the convector may comprise a second heat exchange tube in which the electric heating element is located.

In FIG. 1 shows a front view of a utility model in the case of a single heat-conducting pipe for supplying a heat transfer fluid; in FIG. 2, view A in FIG. 1; Fig. 3 is a front view of a heating convector in the case of two heat exchange tubes for supplying a heat transfer fluid; figure 4 is a front view of a heating convector with two heat exchange pipes, while the upper pipe is designed to supply a liquid coolant, and in the lower pipe there is an electric heating element.

The proposed device includes a heat exchange pipe 1 (Fig. 1) for supplying a heat transfer fluid, on which sections of fins 2 are rigidly fixed, for example by pressing, sections of fins 2 are a cast aluminum structure consisting of a cylindrical base 3, perpendicular to the axis of which through its middle in the vertical direction, the ribbed panel 4 leaves, while the ribs are symmetrical and perpendicular to the panel, and the two extreme ribs forming the front and back surfaces of the heat transfer have a smaller width y than a cylindrical base 3, so that a slight gap is formed in the assembled state between the facing edges,

3 necessary to improve convection, as well as to remove dust and

other contaminants from the internal surfaces of the convector.

In the upper part of the pipe 1 at its final section (for ease of operation) there is a valve for removing air 5, consisting of a housing 6 and a rod 7. In the housing 6 there is a side hole 8. The valve 5 is located in the saddle 9, which is a segment of a cylindrical sleeve, having on one side an internal thread for mounting the crane 5, and on the other, an end face, beveled at an angle of 35 to 55 ° to the axis of the sleeve. The saddle 9 is connected to the pipe 1 so that the internal cavities of these parts communicate.

The end section of the fins 2 of the convector has on the cylindrical base 3 and on the ribbed panel 4 grooves 10, in which, after assembling the convector, a saddle 9 is placed under the crane 5.

If the heating convector has an additional pipe 11 for supplying a heat transfer fluid (Fig. 3), then these pipes are connected by a vertical pipe 12 and the tap 5 is located on the end section of the upper pipe 1.

The heating convector can be combined, i.e. heat up both from a liquid coolant and from an electric current (Fig. 4). Then, in the additional heat transfer tube 13, an electric core 14 is installed, which is an electric heating element enclosed in a solid, liquid or gaseous heat-conducting medium. Pipe 13 with an electric core 14 can

4 located both in the upper and lower parts of the combined

convector. The convector through the cord 15 is connected to the mains and is heated by the passage of electric current through the core 14.

The device operates as follows.

Mains water (or other liquid coolant) enters the convector pipe 1 and heats it and the fins 2. The heated parts of the convector transfer heat to the room by convection and radiation. The air from the room enters the lower part of the convective channel formed by the panel 4, the ribs of the panel 4, and, when heated, rises along the convective channels up. Through the gaps between the ribs of the panel 4, cold air is mixed in.

When the liquid coolant is supplied, an air plug is formed in the upper part of the pipe 1, which does not allow the sections to fully heat up, especially their upper part. To remove air, it is necessary to unscrew the stem 7 by two to three turns from the housing 6 before depressurization. In this case, the opening of the housing located on the axis of the latter opens and air is removed from the pipe 1 through the side hole 8. Unscrewing and screwing the rod 7 is carried out using a screwdriver or a special key.

In a convector with two heat exchange pipes for passing the heat-transfer fluid (FIG. 3), a vertical pipe 12 connecting horizontal pipes 1 ensures circulation and removal of the air plug from the lower pipe.

The use of a combined convector (figure 4) is advisable during the so-called transition period, when the central heating does not work, and the room temperature does not comply with sanitary standards.

The absence of air in the passage of the coolant significantly increases the corrosion resistance of the heat exchanger pipe and increases the heat transfer of the convector as a whole, while saving heat energy. 6
