Description

The utility model relates to the field of heat engineering, namely to the design of a heat exchanger.

Known heat exchange panel ("Heat exchange panel for a heating radiator", patent No. 198603, Russian Federation, patent holder Joint Stock Company "Zlatoust Machine Building Plant" (RU), publ. 07/20/2020), characterized in that it contains upper and lower steel tubular collectors, which are interconnected by steel tubular columns. Each column has a heat exchange panel, consisting of two sections - front and rear. Each section is made of a seamless aluminum profile with heat exchange and stiffening ribs, as well as a longitudinal U-shaped cradle for the column with hooks located along its edges, while 3 rows of hooks are made on the edges of the U-shaped cradle of the front section, and on the edges of the U-shaped one row of hooks is made of the rear section cradle. When installing the heat exchange panel, depending on the errors in the manufacture of the outer diameter of the column and the aluminum profiles of the front and rear sections, a row of hooks of the rear section enters into connection with one of the three rows of hooks of the front section with tight coverage of the steel tubular column with heat carrier. This technical solution was chosen as a prototype.

A disadvantage of the known device is the inability to remove the latch from one end.

The technical result of the proposed utility model is to simplify the maintenance of the heat exchanger due to the possibility of removing the latch on one side to speed up the process of installing or removing the heat-conducting element.

The specified technical result is achieved by the fact that in the latch used in the panel for the heat exchanger, consisting of a lodgment provided with side protrusions, and a latch containing hooks that are formed with the possibility of engaging with the said protrusions, according to this utility model, the angle between the upper and lower surfaces the protrusion located on one side of the lodgment is greater than the angle between the upper and lower surface of the protrusion located on the other side of the lodgment.

There are options for implementing the main technical solution, in which the lodgement has a U-shaped or horseshoe shape.

Thus, the specified set of essential features makes it possible to simplify the maintenance of the heat exchanger and thereby speed up the process of removing the latch and extracting the heat-conducting element, since due to the fact that the angle between the upper and lower surfaces of the protrusion located on one side of the lodgment is greater than the angle between the upper and lower surfaces of the protrusion located on the other side of the cradle, it becomes possible to remove the latch from one side using one hand.

The essence of the proposed technical solution is illustrated by the following description and figures.

In FIG. 1 shows two panels for a heat exchanger connected to each other, with latches located on them.

In FIG. 2 shows a panel for a heat exchanger.

In FIG. 3 shows a lodgement with different angles between the upper and lower surfaces of the protrusion on both sides.

The panel for the heat exchanger (Fig. 1) includes a base 1 provided with at least one retainer.

The latch used in the panel for the heat exchanger consists of a lodgment 2, made with the possibility of placing a heat-conducting element 3 in it, and a latch 4 (Fig. 2), fixing the heat-conducting element 3 in the lodgment 2.

The base 1 is a flat profile of any shape, made of polymer or metal, in particular aluminum. On the base 1 of the panel, mounting channels (not shown in the figure) can be located on all sides along the edges for attaching the panel to a given surface.

Lodgement 2 (Fig. 3) is a U-shaped or horseshoe-shaped protrusion, in which a recess is formed. The shape of the recess of the cradle 2 is determined by the profile of the heat-conducting element 3. The recess may, for example, have a rounded or rectangular shape. The lodgement 2 is designed to accommodate a heat-conducting element 3 (for example, a pipe). On one side of the cradle 2, a protrusion 5 is made, between the lower and upper surfaces of which an angle α is formed. On the other side of the lodgment, a protrusion 6 is made, between the lower and upper surfaces of which an angle p is formed. In this case, the angle α between the upper and lower surfaces of the protrusion 5 is greater than the angle β between the upper and lower surfaces of the protrusion 6. In the preferred embodiment, the angle α is from 68 to 84°, and the angle β is from 42 to 52°.

Additionally, one or more protrusions 5 may be present on the side of the angle α. This design allows fixing pipes of different diameters.

The latch 4 may have a rounded or rectangular shape. The shape of the latch 4 is determined by the profile of the heat-conducting element 3. The latch 4 is open towards the lodgement 2.

The latch 4 is made with the possibility of engagement with the lodgement 2. The latch 4 is fixed on both sides of the lodgement 2. During operation, the fixation occurs on both sides, and removal from one side - from the side of a larger angle α.

Thus, with a steady engagement, the lodgement 2 and the latch 4 form a latch.

The design of the latch in this way allows you to securely fix the heat-conducting element 3 with the maximum fit of the surface of the heat-conducting element 3 to the surfaces of the lodgment 2 and the latch 4.

The proposed device works as follows.

To assemble the heat exchanger, first of all, heat exchange panels are connected to form a heating surface. After connection, the panels are rotated in a horizontal plane or at a given angle. If there are two or more heat exchange panels, the above sequence of actions must be repeated the appropriate number of times.

Further, after joining all the panels to each other, heat-conducting elements 3 are laid in the lodgements 2 located on the inner side of the base 1. After laying the heat-conducting elements 3, the lodgement 2 is covered with a latch 4 and connected by pressing to the lodgement 2, fixing the heat-conducting element 3. In the process of the aforementioned compression, the engagement of protrusion 5 and protrusion 6 of cradle 2 with latch hooks 4. Fasteners (not shown in the figure) are installed in the mounting channels located along the edges of the base 1 of the panel, with which the panels are attached to the wall, ceiling or other surface. The assembled panels of the required dimensions are installed in a heated room. Due to the execution of the heating surface of a highly thermally conductive material (for example, aluminum) and direct contact of the heating surface with the heat-conducting element 3, uniform (over the entire heating surface) thermal radiation or heating is obtained.

Example 1

By pressing the latch 4 is connected to the lodgement 2. In this case, the angle α is 68°, and the angle β is 42°. During the operation of the heat exchanger, due to the selected angles, the process of removing the latch 4 is simplified.

Example 2

By pressing the latch 4 is connected to the lodgement 2. In this case, the angle α is 74°, and the angle β is 46°. During the operation of the heat exchanger, due to the selected angles, the process of removing the latch 4 is simplified.

Example 3

By pressing the latch 4 is connected to the lodgement 2. In this case, the angle α is 79°, and the angle β is 50°. During the operation of the heat exchanger, due to the selected angles, the process of removing the latch 4 is simplified.

Example 4

By pressing the latch 4 is connected to the lodgement 2. In this case, the angle α is 84°, and the angle β is 52°. During the operation of the heat exchanger, due to the selected angles, the process of removing the latch 4 is simplified.

Thus, simplification of maintenance of the heat exchanger is achieved due to the possibility of removing the latch on one side to speed up the process of installing or removing the heat-conducting element.
