Abstract

Heating/cooling body comprises horizontal hollow tubes or plates (1-4), an inlet connection (11), an outlet connection (13), and a distributor arrangement for the heating/cooling medium. The distributor arrangement is designed as a cover for the ends of the heating/cooling body. An independent claim is also included for a spacer, especially for use in the production of hollow plates for the above heating/cooling body.

Description

The present invention relates to a heating or cooling body of the type, as referred to by the preamble of patent claim 1. In particular, the invention relates to convection heating or cooling bodies, which are also called convectors in the following.

Such convectors, which usually have one or more parallel heating plates, which in turn are formed from substantially horizontally extending hollow plates (flat heating tubes), direct the heating or cooling agent from a flow connection via the hollow plates to a return connection, wherein on the heating plate or between several heating plates are usually convector blades that form convection chimneys to dissipate the heated or cooled air in a particular direction (usually up or down) and thereby produce a continuous heat exchange through the air flow.

Examples of convector radiators can be found in the German Utility Models DE 296 17 392 U1 and DE 297 05 694 U1.

It is the object of the present invention to design a generic heating or cooling body so that it has a high functionality and a reliable optimized heat or cold transmission allowed. In particular, flexible installation options should be created and a visually appealing construction should be made possible.

This object is achieved by the features listed in the characterizing part of patent claim 1. The sub-claims relating to the heating or cooling body describe preferred embodiments of the invention.

The inventive design of the distribution of the heating or cooling medium in the convector body advantageously provides the opportunity to put the flow and return connections as desired at different points of the heating or cooling body. The arrangement of separate distribution channels, as proposed according to the invention, further increases the flexibility in the design possibilities for a convector body. A particularly compact arrangement can be achieved if the feed connection is connected via a through the return passage of a first distribution channel extending therethrough to the flow section of a separate distribution channel. An externally appealing appearance is provided according to the invention when the vertical end faces of the convector body have substantially rectangular, separate distribution channels which provide a lateral termination.

The supply and return connections of a convector body according to the invention can according to the invention open directly or via a section of a distribution channel into an upper, but also into a lower divided hollow plate and then be connected further via the distributor arrangement and the other hollow plates.

The invention further relates to a spacer, which is used in particular for the production of hollow plates for a heating or cooling body. In the preparation of the hollow tubes configured as rectangular tubes spacers must be inserted between the flat portions of the hollow plates to be bent to each other be used to prevent the cavity is pressed during processing. For this purpose, round discs are used in the prior art, have the flow openings. However, such round discs are critical in that they may slip during the manufacturing process and thus can no longer maintain their function as spacers.

The invention solves the above problem by providing a spacer having an attachable part which can be attached to the front side of the hollow plate sections and spacers projecting therefrom, which project into the cavity of the hollow plates and in particular have a height substantially equal to the internal spacing of the hollow plate parts.

Because the spacers according to the invention form with their Ansetzteil the frontal closure of the hollow plates and thus immovably arranged, the projecting spacers are automatically arranged immovable, so that in the production no disturbances due to shifted spacers are more to be feared.

In a preferred embodiment of the spacers according to the invention, at least one, preferably two fork-like, protruding spacer strips protrude from a plate which is in the form of an attachment part and which is substantially flat and corresponds to the end cross-section of the hollow plate.

Fig. 1 shows a convector radiator of a first embodiment according to the present invention in an exploded perspective view, while Fig. 2 illustrates this radiator in the assembled state. The radiator according to this first embodiment is provided overall with the reference numeral 10.

The convector body 10 has on each of its flat sides four hollow plates 1, 2, 3 and 4, which transport a heating medium as flat heating tubes. Between Hollow plates are arranged convector blades 5, which form chimneys for the convective air passage.

At the front end side, the convector body 10 has the distribution channel 12, while at the rear end side of the distribution channel 17 is mounted. The two distribution channels are connected via the connecting tube 16 with the hollow plates 1 to 4 in each case in the frontal region in connection. The attachment between the connecting tube 16 and the connection points on the hollow plates can be realized for example by resistance welding.

The rectangular distribution channel 12 is divided by a horizontally extending web into two sections, namely a forward section 14 and a return section 15. This can be clearly seen in the cut-away area of FIG. 1. The distribution channel 17, however, is formed as a continuous rectangular tube.

In the lower region of the distribution channel 12, namely in the return section 15, there is the return port 13 of the convector body, while the flow section 14 has the flow connection 11.

When carrying out heating medium through the convector body shown in FIGS. 1 and 2, the following flow sequence results, which is recorded in FIG. 2 by arrows on the hollow plates. From the feed connection 11 from the heating medium reaches the flow section 14 and flows through the connecting tube 16 in the uppermost first hollow plate 1 (on both sides of the convector body) and from here again in the rectangular distribution channel 17. From the distribution channel 17, the heating medium is now in the Hollow plates 2, 3 and 4 distributed and flows in the opposite direction back into the lower return section 15 of the distribution channel 12, where it exits from the return port 13.

A particularly compact embodiment of a convector body 20 with a bottom-side supply connection is shown in FIG. For the Fig. 3 and in the further also for Figs. 4 to 9 is that the same reference numerals or reference numerals denote with identical last digits components corresponding to those in Figs. 1 and 2.

The convector body 20 of Fig. 3, with the exception of the manifold 22 has the same structure as that of Figs. 1 and 2, and he also has the same flow guide except for this difference. The convector body 20 is a radiator with a bottom-side flow connection 21. This bottom-side flow connection 21 passes as a tube through the return section 25 of the distribution channel 22 and opens up in the flow section 24, from where the heating medium is then in turn passed to the top hollow plate 1. The flow pattern is the same as the convector body 10, i. the heating medium flows via the hollow plates 2, 3 and 4 back into the return section 25 and exits from the return port 23. With the implementation of the flow pipe 28 through the return section 25 space is saved in the interior of the radiator and it can, for. B. more slats 5 are arranged. The upper port 21 'in the flow section 24 can either be blind flanged or provided with a vent.

A particular advantage brings the present invention possible summary of several connection variants with it.

FIG. 4 shows a front and a rear end perspective view of a convector body 30 according to a third embodiment. This convector body 30 has at the connection end face shown on the left a running only on the lower hollow plates 2, 3 and 4 rectangular distribution channel 32, which forms a total of only one return section. On the rear venting end shown on the right, a rectangular distribution channel 37 extends over all hollow plates.

The convector body 30 shown here is a radiator which has on the bottom side both the flow connection 38 and the return connection 33. The flow connection 38 leads as a pipe up to a commonly used fitting, which distributes the heating medium on both sides of the first hollow plate 1. Also on the venting end shown on the right hand side two ports are provided on the distribution channel 37, of which the lower port 39 can be used as a further return port, while at the unspecified upper port, for example, a vent valve can be attached.

According to the invention, a connection with an integrated valve can be realized. The valve in this case forms part of the convector body and is in particular clad accordingly.

A similar convector radiator 40 is shown in FIG. 5. The difference to the Konvektörkörper 30 of FIG. 4 is that on the port side shown on the left side of the distribution channel 42 extends over all four hollow plates. Also, this distribution channel 42 is separated below the top hollow plate by a not visible here separation device. From the feed connection 48, a pipe leads behind the distribution channel 42 in its upper flow region, while the return connection 43 is provided at the bottom of the distribution channel 42. As can be seen from the diagram on the right, a return 49 as well as a ventilation connection at the top can also be provided here again on the opposite end side.

The above embodiment may also be configured as a convector heater having a center port.

In Fig. 6, an alternative embodiment of a convector radiator according to the invention is now shown. This radiator has (on both sides) a divided lower hollow plate with a flow side 4a and a return side 4b. The two illustrations in Fig. 6 show the same radiator 50; the upper illustration is only slightly tilted to make the flow port 58 and the return port 59 visible. The flow guide is in this radiator the following (see also the arrows): Through the feed port 58, the heating medium enters the first half-shell half (lead half) 4a and is introduced from there via the distribution channel 52 in the upper hollow plates 1, 2 and 3, where it flows opposite to the direction indicated on the hollow plate half 4a. The distribution channel 52 is not divided, ie in this embodiment, the role of the separate lead section (see Fig. 1, reference numeral 14) is taken over by the hollow plate half 4a itself. After flowing through the hollow plates 1, 2 and 3, the heating medium enters the rear manifold 57 and is directed from there down into the hollow plate half 4b, which forms a return half. The return port 59 is connected to the hollow plate half 4b and passes the heating medium back out of the radiator.

With this construction, it is possible to provide a convector according to the invention with a bottom-middle connection.

FIG. 7 corresponds to the embodiment shown in FIG. 6 with regard to the basic flow guidance. The radiator 60 of FIG. 7, however, is a radiator with three heating plates, which are each formed of continuous hollow plates 1, 2 and 3. The lower hollow plate of the front heating plate is in turn divided into the flow and return halves 4a and 4b, so that the already discussed with reference to FIG. 6 flow is achieved. In contrast to the radiator 50, however, the radiator 60 instead of the rectangular distribution channels pipe distributor 62 and 67 with conventional fittings. Also, this radiator 60 has the bottom connections 68 (flow) and 69 (return).

FIG. 8 again shows an embodiment of a heating element 80, which corresponds with respect to the flow guide to that shown in Fig. 1. This radiator 80 differs from the radiator 10 shown in FIG. 1 in that Instead of the rectangular distribution channels now pipe manifold 82 and 87 are used. Furthermore, the return section 82 has a downwardly outgoing return port 83 and extends to return the heating medium through the three lower hollow plates 2, 3 and 4. In the right view again can be seen that the rear manifold 87 all four hollow plates 1 to 4 connects with each other.

The embodiment of the radiator 90 according to FIG. 9 corresponds in principle completely to that shown in FIG. 8, with the difference that the radiator shown here has only two superimposed hollow plates 1 and 2 on each side. The heating medium flows from the feed connection 91 through the hollow plate 1 and is passed via the return pipe manifold 97 through the hollow plate 2 back to the return port 93, which in turn goes down to the ground.

In Fig. 10, the principle of inventive spacer is now shown. The heating tube spacer assembly is designated by reference numeral 100. It consists of an already curved in shape hollow plate piece 1 and the spacers, which have a closure plate 101 and fork-like spacers 102. The end plates 101 are adapted or attached during manufacture to the end faces of the hollow plate 1, so that the fork-like spacers 102 penetrate into the cavity 103 and can serve as a spacer for the two lateral plates of the hollow plate 1. These spacers can neither slip nor block the flow through the hollow plate. 1

In Fig. 11 shows a further training possibility for the adjacent hollow plates. The hollow plates 1, 2 and 3 of the upper illustration and the two hollow plates 1 and 2 in the lower illustration were produced by rolling with the aid of profile rollers in the form of closed heating registers. In the embodiment shown here, the adjacent part A at a pitch of the hollow plate sections of about 70 mm has a width of about 10 mm.

Figures 12 and 13 illustrate a half shell construction of a convector body. In Fig. 12, the convector body is shown in perspective view in different sectional planes I, II and III. The representation I shows the convector body in half shell construction with the numbered from top to bottom flow channels 1 to 5 uncut. In the view II, the front part of the convector body is cut away in the region of the connections, while the illustration III shows a convector body cut a little further back.

In connection with the unfolded view of such a half-shell convector body shown in Fig. 13, it is now clear that this has heating plates, which are composed of a front half-shell V and a rear half-shell H. The front half-shell V has the convexly curved flow channels 1 to 5, while in the rear half-shell H overflow channels U are provided which forward the heating medium at suitable locations from one flow channel to the other. These overflow channels U are also designated in FIG. 12, it being apparent in section III that at the locations where the overflow channels U are present, the heating medium can pass from a flow channel into an adjacent flow channel.

By a suitable arrangement of the overflow channels U, the desired flow guidance can be generated, in particular a flow guide, as previously described with reference to the previously illustrated embodiments.
