Abstract

FIELD: heat engineering.

SUBSTANCE: invention can be used in heating devices. In a heating device with convection chambers, including a coil with convection plates installed on it, while the convection plates have grooves in the shape of the coil, the first convection plates tightly cover the surface areas of the coil and, due to their shape, form the central convection chambers, the subsequent convection plates tightly cover sections of the surface of the first plates and, due to their shape, form side convection chambers; inlet and outlet channels for air are provided in the convection chambers.

EFFECT: increase in the manufacturability of the assembly and the efficiency of convective heat transfer.

Description

The invention relates to heating appliances and is used for heating buildings.

Known heaters (convectors), made of a bent or welded pipe (coil) with mounted (pressed) on her convection plates in the form of ribs.

The closest technical solution (prototype) is a heating device (see patent dated 24.11.2003 No. RU 2 265 777 C2), consisting of a pipe for supplying heat carrier with heat-releasing surfaces fixed on it, made in the form of two stamped steel sheets, installed in this way that the pipes for supplying the coolant are located in the semi-cylindrical sections of the plates. The disadvantages of this design is the lack of convection of the inner surface of the sheets and the coil, the possibility of using only two plates on one coil, low air mobility at the heat-releasing surface.

The task of developing the invention is to solve technical problems:

- improving the manufacturability of the assembly;

- increase in air mobility at heat-releasing surfaces (convection plates and coil);

- creating a tight contact between the convection plates and the coil;

- an increase in the area of heat-releasing surfaces with a low metal consumption.

The technical result is achieved:

- to improve the manufacturability of the assembly, due to the absence of the need to press the plates onto the coil;

- to increase the mobility of air near the convection plates and the coil, due to the creation of convection chambers with inlet and outlet convection channels;

- to create a tight contact between the coil and the convection plates, due to the shape of the convection plates and the creation of a clamp by fasteners or connection by welding or soldering;

- by increasing the area of the heat-releasing surface, due to the shape of the surface of the conventional plates and the successive imposition of the plates one on top of the other with a dense coverage of the coil.

The description of the invention is supplemented by drawings, which show:

- Fig. 1 - Cross section, showing the relative position of the coil, convection plates and decorative panel in the product;

- Fig. 2 - Remote element A (the place where the coil is surrounded by convection plates).

The heater with convection chambers (device) includes a coil with convection plates installed on it. Convection plates have serpentine-shaped grooves for tight contact and high heat transfer. The first convection plates tightly cover the surface of the coil and form central convection chambers due to their shape. Subsequent convection plates tightly cover the surface of the first plates and form side convection chambers due to their shape. The convection chambers have inlet and outlet channels. The number, shape and location of the convection chambers are determined by the configuration of the heater and may vary depending on the desired appearance and heat transfer of the product. Shut-off and control valves, thermostats, Mayevsky valve, mounting elements and fasteners can be installed on the device. The device can be equipped with decorative panels or housing. The device may be provided with forced air circulation. Also convection plates can have louvers or holes for additional air circulation in the device.

The heater with convection chambers works as follows:

- the coolant moves along the coil, giving off heat to its walls, the walls of the coil, in turn, give off heat to convection plates, tightly covering the sections of the outer surface of the coil, and the open sections of the coil give off heat directly to the air;

- convection plates due to their shape form closed chambers in which the air is heated;

- heated air rises naturally (or is forced in) and exits the exhaust convection ducts;

- a vacuum is created in the chambers, as a result of which colder air is drawn into the inlet convection channel;

- due to convection, a constant air exchange and heating of the room air is created;

- also heated elements of the coil and convection plates emit heat into the room due to radiation.
