Description

The utility model relates to heating appliances, and can be used in residential, office and industrial premises.

A heating convector is known, including a heating element with end connecting pipes, enclosed in a protective casing containing a front panel, an upper panel with air outlet slots and two side walls, at least one of which has a window for outputting connecting pipes equipped with a vertically oriented removable cover ( RU No. 27336 U, IPC F24D 15/00 (2000.01), publ. 20.01.2003).

Known heating wall convector, containing a heating element made of two pipes for supplying a coolant, with convection lamellas-lamellas rigidly mounted on them, brackets, a housing with grilles in the upper and lower parts for air circulation, while the pipes of the heating element are located in two parallel vertical planes in such a way that the pipe axes are offset from the axis of symmetry of the lamella plates by a distance L satisfying the condition 0.1⋅D <L≤0.5⋅ (V-D), where L is the distance between the center of the pipe and the axis of symmetry of the plate mm; D - pipe diameter, mm; In - the width of the plate-lamella, mm (RU No. 159876 U, IPC F24D 3/16 (2006.01), F24D 19/00 (2006.01), publ. 02.20.2016).

Also known is a convector selected as the closest analogue, comprising a heat exchange section for a coolant, made of a U-shape from a pipe of circular cross section, in the straight sections of which heat-dissipating elements are fixed uniformly at an angle to the pipe in the form of rectangular plates with flanged holes, made by stamping with a cylindrical flanging of holes of height H, by means of which the plates are mounted on pipes and flanging the long edges of a rectangle of height h, with H> h (patent RU No. 45812, F24H 9/00 (2000.01), publ. 27.05.2005).

Known convector type heaters have a low heat transfer coefficient.

The task was to increase the heat transfer capacity of the heater.

To solve this problem, in a heating convector containing a heat-exchange U-shaped pipe placed in the casing with heat transfer agent input and output and rectangular heat-transfer plates having flanged openings and edges are flanged, by means of which heat-transfer plates are uniformly mounted on straight sections of the U-shaped pipe, characterized in that on heat exchanging plates on both sides of the holes symmetrically with respect to the longitudinal axis, louvre-type holes with fixed lamellas are made, and additional flanging of the plates made symmetrically with respect to the axis of the plates, while the flanging of the edges is made on short edge sections. In the particular case of execution of the track of the louvered holes of the heat exchanger plates, they are 10-12 mm wide and are located at a distance of 15-20 mm from the axis of the holes for the pipes.

Distinctive features together and separately, namely, that on the heat transfer plates on both sides of the holes there are louvre-type openings with fixed slats symmetrically relative to the longitudinal axis, and additional flanging of the plates made symmetrically with respect to the axis of the plates, while the flanging of the edges is made on short edge sections, allow to increase the heat-transfer ability, while the device has a simple, reliable design.

As a result of the analysis of the prior art, including a search by patent and scientific and technical sources of information, an analogue characterized by features identical to all the essential features of the claimed technical solution was not found.

The claimed technical solution is illustrated by the following drawings:

FIG. 1 - heating convector, general view;

FIG. 2 - the same, heat transfer plate;

FIG. 3 is the same, section BB in FIG. 2;

FIG. 4 - the same, view A, enlarged;

FIG. 5 is the same, section BB in FIG. 2.

The heating convector comprises a casing 1, in which a heat-exchange U-shaped pipe 2 with means for introducing and discharging the heat transfer medium, rectangular heat-exchange plates 3, having openings 4 with flanging 5, through which they are installed on straight sections of the U-shaped pipe, and flanging 6, are placed, made in short marginal areas.

On the heat exchange plates 3 on both sides of the holes 4 symmetrically with respect to the longitudinal axis, tracks 7 of louvre-type openings with fixed lamellas 8 are made.

Lanes 7 of the louvered holes of the heat exchanger plates are 10-12 mm wide and are located from the axis of the holes 4 for the pipes at a distance of 15-20 mm. It was experimentally established that reducing the width of the tracks adversely affects the efficiency of the convector, as well as increasing their width or number. The most efficient heat transfer was achieved when the area of the finned part of the blinds occupied 30-40% of the total area of the plate.

Additional flanges 9 are made symmetrically with respect to the axis of the plates on the heat transfer plates, by means of which the heat transfer plates are supported on each other during assembly of the bag

In addition, the metal consumption of the device decreased, because decreases the number of installed heat transfer plates 3.

The convector works as follows.

When the coolant is supplied to the heat-exchange U-shaped pipe 2, the air is heated between the heat-exchange plates, sent by the louvres 9 of the blinds to the holes 10 of the casing 1 and goes out. Thus, a vertically directed air heat flow is formed. The heat transfer plates 3 are assembled on a heat exchange U-pipe end-to-end with each other at a distance of height. By performing on the heat transfer plates of the tracks 7 openings of the louvre type with fixed lamellas 8, additional heat transfer is ensured.

The utility model provides high heat transfer efficiency, has a simple, reliable design and allows to reduce the metal consumption of the convector.

The claimed heating convector meets the requirement of industrial applicability and is possible for implementation on standard processing equipment.
