Description

The utility model relates to the field of heating equipment, namely to radiators for heating buildings and structures for various purposes.

A radiator is a radiator that radiates heat through radiation and convection. Currently, a promising direction is the intensification of heat transfer processes by increasing the convective component in the total heat transfer of the radiator.

Known sectional radiator (Patent RU for utility model No. 122469, F24D 3/00, publ. 11/27/2012), consisting of sections hermetically connected to each other, containing in each section a vertical pipe communicating with horizontal upper and lower collectors for the passage of coolant, wherein the vertical pipe is made with bilateral symmetrical vertical fins connected to the front and rear panels, forming a stiffener, with heat transfer vertical three ribs placed on its surface having different lengths. The upper edge of the rear panel is finger-shaped and bent toward the upper collector; a vertical pipe and a stiffener are made with external wave-like protrusions; wherein the longitudinal sides of the heat transferring stiffeners are made narrower by two third lengths from below; and the upper edge of the rear rib has a continuation in the form of a curved wall, covering the upper collector and going under the inclined upper edge of the rear panel, with the formation of an asymmetric closed loop slightly biased forward over the upper collector.

Also known is a sectional radiator (Patent RU for utility model No. 123123, F24H 3/00, publ. 12/20/2012), consisting of sections hermetically connected to each other, containing in each section a vertical pipe communicating with horizontal upper and lower collectors for the passage of coolant moreover, the vertical pipe is made with bilateral symmetrical vertical fins connected to the front and rear panels, forming a stiffener with heat transfer vertical three ribs placed on its surface, having different inu. The front panel of each section is made wavy, and when the sections are connected, the wave decline of one panel corresponds to the wave rise of the next panel with the formation of a gap. In this case, the upper edge of the panel is made finger-shaped bent towards the upper collector; the upper edge of the rear panel is also finger-shaped and bent toward the upper manifold; the upper edge of the middle rib has a continuation in the form of a curved wall that covers the upper collector and goes under the inclined upper edge of the rear panel, with the formation of an asymmetric closed loop slightly biased forward over the upper collector.

In these utility models, due to the proposed geometry of the panels and fins, an air stream of heated air is created and, consequently, the convective component in the overall heat transfer of the radiator is increased. However, such designs are technologically quite difficult to manufacture.

The closest technical solution is a sectional type radiator, which consists of two types of sections hermetically connected to each other, at least one of which the front panel is inclined relative to the vertical axis, and when connecting the sections to each other, the edges of the front panels are at least at least two adjacent sections of different types form an angular gap, which is formed by the divergence of the front panels of adjacent sections of different types in the upper and lower parts by an angle greater than 0 °. Each section contains a vertical pipeline in communication with the horizontal upper and lower collectors for the passage of coolant, a stiffener that connects the front and rear panels. At least one of the sections contains heat transfer ribs placed perpendicular to the stiffener between the front and rear panels (Patent RU for utility model No. 144024, F24D 3/00, publ. 08/10/2014). Between the ribs formed channels. This design of the radiator allows you to increase the convection component of heat transfer by creating additional traction in the area of divergence of the front panels of adjacent sections of different types with the formation of corner slots.

The disadvantage of this technical solution is the limited convective air movement inside the sections. This is due to the fact that the slotted openings of the front panels do not provide sufficient traction to move the heated air up.

The technical result of this utility model is to increase the proportion of convective component in the total heat transfer of the radiator by increasing the intensity of movement of the heated air flow inside the sections.

The specified technical result is achieved in that in the heating radiator, consisting of sections hermetically connected to each other, each of which contains at least one vertical pipe in communication with the horizontal upper and lower collectors for the passage of the coolant, a stiffener connecting the front and rear panels between which heat transfer ribs are located parallel to the panels, ACCORDING TO THE USEFUL MODEL, the distance between the longitudinal faces of the heat transfer ribs of adjacent sections does not exceed 3 m m

Each section may include a top panel with holes located between the front and rear panels.

The holes in the upper panel may be slotted and may contain plates, one side of which is connected to the edge of the hole and directed inwardly to the section.

The ends of the heat transfer ribs can be located at a distance from the lower and upper collectors.

Each section of the heating radiator may contain two vertical piping, on which heat transfer ribs are placed.

The extreme sections of the heating radiator can be covered with side covers. Side covers may contain holes, which in a particular case are slotted.

Side covers can be made with a seat to prevent displacement and fastened to the extreme sections of the radiator with screws.

The essence of the utility model is illustrated by drawings.

In FIG. 1 shows a general view of a section of a heating radiator (with one vertical pipe).

In FIG. 2 shows a section of a heating radiator (side view): with one vertical pipe (a) with two vertical pipes (b).

In FIG. 3 shows a heating radiator assembly with two vertical pipelines (rear view) and its cross section AA.

In FIG. 4 shows a radiator assembly with a side cover.

Each section of the radiator contains at least one vertical pipe 1, communicating with the horizontal upper manifold 2 and lower manifold 3 (Fig. 1, 2). The radiator section has a front panel 4 and a rear panel 5, between which there is a stiffener 6 and heat transfer ribs 7. The front 4 and rear 5 panels are made in the form of flat solid surfaces with a width not exceeding the length of the horizontal collectors 2, 3. The front panel 4 is placed on the entire height of the section along the vertical pipe 1. In order to better move and heat the air in the area of the collectors, the ends of the heat transfer ribs 7 are placed at some distance from the upper collector 2 and lower collector 3 (Fig. 1, 2). The rear panel 5 is shorter in length than the front panel 4 with the formation of sections 8 in the lower and upper parts of the radiator when connecting sections (Fig. 3), which are used to place mounting brackets.

The heat transfer ribs 7 are placed symmetrically on both sides of the vertical pipe 1 and the stiffeners 6. The longitudinal edges of the heat transfer ribs 7 when connecting the sections are placed as close as possible to each other, with a distance between them of no more than 3 mm, to form convection channels 9 (Fig. 2, 3). Each section contains a top panel 10 with holes 11. The top panel 10 is located between the front 4 and rear 5 panels and can be formed during injection molding or made separately in the form of a cover. The holes 11 can be slotted and contain plates 12, one side connected to the edge of the holes and directed inwardly to the section (Fig. 2). Side covers 13 (FIG. 4) having openings 14 for accommodating horizontal collectors 2, 3 can be mounted on the extreme sections of the radiator. Slit openings 15 are made in the side covers 13 for air to enter the inner part of the radiator section. The cover 13 has a seat 16 to prevent displacement. The cover 13 can be attached to the radiator section with screws. All edges of the ribs, panels, plates can be made with rounded corners, which ensures high operational safety.

The radiator production includes the following operations: production of side covers and upper panels (if they are separate structural elements) from an aluminum alloy; manufacturing a mortgage element of steel for placement in a mold; melt preparation and high-pressure casting of aluminum alloy, grinding, machining, assembly operations. During assembly, the individual sections are interconnected by flash butt welding or with the help of nipples and special sealing gaskets. On the extreme sections, side covers are installed that have seats and are fixed to the radiator by screws. The upper panels can be attached in various ways, for example, using heat-resistant adhesive joints, guide grooves, locking joints, clips, etc. After assembly, they carry out painting, hydraulic tests, and packaging of the radiator.

The heating radiator operates as follows. After connecting to the heating system, the heated coolant enters the radiator. When the coolant moves along vertical pipelines 1 and horizontal collectors 2, 3, heat is transferred to fins 6, 7 and panels 4, 5 of the radiator sections, which, in turn, heat up and transfer heat to the room through radiation. This creates favorable conditions for air convection. Cold air enters the radiator from below and when heated rises up through convection channels 9. These channels 9, due to the very close location of the longitudinal faces of the heat transfer ribs of adjacent sections to each other (with a distance of no more than 3 mm), provide vertically directed movement of air flows and enhance the natural traction. Slotted holes 11 in the upper panels 10, covering the radiator sections from above, and the plates 12, directed into the sections, further orient the air flows in the vertical direction when leaving the radiator, which enhances the air draft. Thus, the proposed heating radiator provides an increase in the intensity of movement of the heated air flow inside the sections and an increase in the proportion of convective component in the total heat transfer of the radiator. As a result, the nominal heat flux of the radiator per unit area is increased without complicating the design, as well as without increasing the overall dimensions and weight of the product. At the same time, it is possible to connect to the heating system according to all known schemes, as well as unification of installation. The presence of upper and side panels on the radiator sections provides a high degree of safety and ease of use.
