Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a heat exchanger formed of a plurality of juxtaposed components, and more particularly to a heat exchanger for warm water central heating.

[0002]

2. Description of the Related Art Components for a heating element used as a heat exchanger are cast, for example, from gray cast iron. A profitable production is obtained by stamping out two side plates each from a steel plate. The side plates are juxtaposed to one another after forming a recess which later defines a hollow space and are welded along their perimeters.

A disadvantage of such components is that a separate tool must be procured for each shape (eg, component height or width), and thus only a small number of models are provided in practice. Individual adaptation to the desired predetermined dimensions is not possible. Furthermore, only the surfaces of these components can be used to conduct heat to the air in the room, and thus multiple heating elements, and thus large heating elements, to provide a given heating output in multiple rooms Is required, and this is a disadvantage. This point is not preferable.

On the other hand, plate-type heating elements (flat radiators) are additionally known which have a convection plate additionally welded in order to conduct heat to the air in the room, but the production of convection plates differs in size. Multi-divided tools are required.

[0005]

SUMMARY OF THE INVENTION The object of the present invention is to be able to completely and individually address the individual requirements regarding the size of the components, in particular the requirements regarding the height, at low cost and from the components in the surroundings or in the room. It is an object of the present invention to provide a heat exchanger in which the heat transfer to the air can be reduced so that the overall required size of the heat exchanger can also be reduced.

[0006]

According to the present invention, there is provided a heat exchanger, wherein a part of a polygonal tube extruded from aluminum or an aluminum alloy is provided as the component of the heat exchanger. Comprising two sides facing each other and parallel to each other, wherein the components are juxtaposed such that they overlap with each other;
The upper and lower end surfaces of the component are connected to each other by a bottom portion and a cover. It is characterized by being hermetically connected to each other.

In the present invention, in particular, a plurality of polygonal tube profiles are used. These tube profiles were extruded (sometimes almost endless)
Individually cut from the profile, significantly increasing the contact area with the surroundings and easily increasing the chimney effect.

[0008] Advantageous configurations, inventive additional configurations, and advantageous configurations are characterized in the dependent claims.

BEST MODE FOR CARRYING OUT THE INVENTION

FIG. 1 shows the two components 1 of the heating element in a horizontal sectional view. These components 1 are formed from the individual parts of a closed polygonal tube. The polygonal tube is extruded from aluminum or an aluminum alloy into a member of, for example, 6 m. Individual sections are cut from these extruded tubes, the length corresponding to the desired height of the heating element. These individual parts, as shown in the figure,
The mutually parallel sides 2 are arranged one above the other and joined together. In particular, the ends of the sides 2 are connected via a longitudinal profile 3, the ends of the sides 2 and the longitudinal profile 3 being square (eg rectangular)
Produces a closed cross section of This cross section may be reinforced by the lateral wall 4. A strip 5 protrudes from the vertical profile material 3. The strip 5 supports a catenary-like outer contour 6. This provides an internal space or a double internal space 7 for the heat transfer liquid. At this time, the strip 5 supporting the outer contour portion 6 is adjacent to the heat transfer liquid and has a chimney-like convection line 8.
To form Convection line 8 favors heat dissipation.

The connection with the component 1 arranged side by side can be configured in a multiplex manner. It is effective to join the side portions 2 facing each other and overlapping with an adhesive layer 10. The adhesive layer 10 also provides a seal at the same time. Further, since a communicating portion for allowing the heat conducting liquid to flow through must be formed, it is effective to use the heat conducting liquid to make the communicating portion more secure. For example, the communication department
Circular holes can be produced in the upper region of the sides 2 which are in contact with one another and at the same time by means of a gripping device which pulls the edges of these holes in the extrusion direction through the holes. Further bending of the pulled edge with a corresponding counter tool results in a kind of riveting and sealing with the adhesive layer 10. In the lower region of the side portion 2, reflux of the heat transfer liquid must be performed, so that a similar communication portion also occurs in this lower region.

However, it has been found that it is not always necessary to punch out a circular hole, for example. For example, having one side with a hole of another shape (for example, a square break)
A break corresponding to the side to be placed on this side may be provided, in which case the two edges facing each other may be provided with a connecting sheet which is suspended and bent at these edges. In this case, after the component 1 has been seamed or its sides 2 have been joined together and the connecting lamella has been penetrated, a mechanical fixed holding is achieved in addition to the holding and sealing caused by the adhesive layer 10. Bend the connecting sheet so that

However, when selecting a component 1 having a double internal space 7, it is also necessary to transfer the heat transfer liquid from one of the internal spaces of one part into the adjacent internal space. In this case as well, a hole may be punched out, but it is easy to provide the notch 11 in the region of the upper ridge and the lower ridge which partition the internal space.

After the components 1 forming the heating element have been sufficiently finished and combined in this way, the lower part of the heating element is
And the upper part is closed by the cover 13 to be placed. In this case, both the bottom 12 and the cover 13
It extends between the two outer sides 2 of the formed heating element and the entire row of longitudinal profiles 3. In this case, an additional mechanical holding is effected, for example, by machining all the end faces of the side part 2 so that it retreats somewhat with respect to the end face of the longitudinal profile material 3 so that the bottom part 12 and the corresponding cover 13 have their long end parts This can be achieved by being positioned between the vertical profile members 3 by a surface, the upper or lower surface of which rests on the end surface of the side 2. The bottom 12 and the cover 13 may be provided continuously for one heating element over all the components 1 thereof, but may be provided, for example, in multiples or interrupted at the end of one component 1 respectively. ,
Depending on the case, it may be configured arbitrarily, such as extending so as to cover only one component of the heating element.

The connection between the component 12 and the bottom 12 or the cover 13 can be made in various ways. In this case, bonding is also possible, and welding or the like is also applicable. However, in each case, it is necessary to make a mechanically secure and sealed connection.

If the bottom 12 and the cover 13 are manufactured in a rectangular shape corresponding to the rectangular shape in the height direction of the side portion and the entire shape of the vertical profile material, the convection conduit is exposed,
Both the strips 5 and the contours 6 are additionally considered as heat dissipating surfaces and are therefore expedient because they enlarge the heat dissipating surfaces. However, the cover surface may cover the convection duct 8. In this case, it is necessary to form the cover surface in a sieve shape or a protective grid shape.

A small volume for the heating liquid, generally a low operating weight, and a rapid processing of the heating medium can be achieved by surrounding the exclusion. Thus, foamed plastic rods with advantageously closed holes may be used, as well as closed metal or plastic containers.

The surface of the component 1 can be emphasized and emphasized by arranging the individual components in color.
While it is preferred to color and anodize the surface of the component, the surface or surface element may be chromed, lacquered, or coated with plastic. In this case, the corrosion resistance is respectively improved.

The heating element may be configured correspondingly to the fact that the space accommodating the heating element is divided. In this case, the individual components are not directly connected to one another, but are spaced apart from one another or form individual groups which are connected by suitable supply and discharge pipes. Fillet welding, for example, makes it possible to independently and / or later mount a curved body that can be used to receive various mechanical devices. The curved body is used, for example, for receiving a towel dryer, but can also be used for receiving a speaker, a simple additional mounting surface, and the like.

The connection of the heating element can take place via a conventional armature 9 which is screwed into a respective hole in the outer side 2. On the other hand, a connection is arranged in the bottom region of the outer component 1 having two internal spaces 7,
At this time, one internal space 7 may be connected to the outward path, and the second internal space may be connected to the return path to divide the internal space 7 so as to form an upper internal space and a lower internal space. Such a division can be fitted with a valve to regulate the heating,
The operating elements of this valve can then be linked outwards, while the valve itself bridges the upper interior space and the lower interior space.

When connecting the components, a so-called Clinsch method can be adopted, and as the sealing portion, an aligned packing can be used as a rubber ring by press-fitting the packing. Through-hole and rubber packing
In this case, it may be attached to the perforated clinch element.

If at least one or some of the components is provided with an electric heating element, an advantage arises in the heating, in particular during the transition time. The radiator may be made up of one component or a small group of these components.
