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 they is designated by the preamble of claim 1. In particular, the Invention convection heating or cooling body, which in the following also convectors to be named.

Such convectors, usually one or more heating plates arranged in parallel have, which in turn from essentially horizontally extending hollow plates (flat heating pipes) are formed, conduct the heating or cooling medium from one Flow connection via the hollow plates to a return connection, with the Heating plate or between several heating plates are usually convector fins Form convection chimneys to the heated or cooled air in a be derive correct direction (mostly upwards or downwards) and thereby a con to establish continuous heat exchange via the air flow.

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

The generic DE 32 01 439 A1 shows an arrangement of a radiator in which the heating medium enters a manifold and from this manifold into all Heating plates is derived. Each flat tube is connected to the same via two connections Collector pipe connected, so that the heating medium immediately from the flow connection all flat tubes is distributed.

CH 341 292 describes a type of flow control in which the Collecting pipe pieces with associated flat tubes and with each other in a conductive Connect. With regard to a division of the flow is only suggested closing the middle piece of manifold below so that the Heat transfer medium first through the five top tubes and then through the five bottom tubes flows.

It is the object of the present invention to provide a heating or Design heat sinks so that they are highly functional and reliable optimized heat and cold transfer allowed. In particular, flexible one construction possibilities created and a visually appealing construction enables become.

This object is achieved according to the invention in the list in claim 1 times solved. Describe the subclaims relating to the heating or cooling element preferred embodiments of the invention.

The advantages to be achieved according to the invention are based on a heating or Heat sinks with essentially horizontal hollow pipes or plates, a flow connection and a return connection as well as a distributor arrangement for the heating or cooling medium, according to the invention the flow connection with a Entry side of a single first hollow pipe or plate or a single one A pair of hollow pipes or plates is connected, which the heating or  Cooling medium passes downstream via its outlet side into the distributor arrangement, from where from it via the remaining hollow pipes or plates to the return connection is returned.

The inventive design of the distribution of the heating or cooling medium in the Convector body advantageously offers the possibility of forward and return to place connections at different points of the radiator or heat sink as required. The arrangement of separate distribution channels, as proposed according to the invention, increases the flexibility in the design options for one Konvektorkörper. A particularly compact arrangement can be achieved if the Flow connection via a through the return section of a first distribution channel pipe running through with the flow section of a separate distribution channel connected is. An externally appealing appearance is then according to the invention provided when the vertical end faces of the convector body in the have essentially rectangular, separate distribution channels that have a lateral Provide conclusion.

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

The invention also relates to a spacer, in particular for Manufacture of hollow plates for a heating or cooling element is used. In the Manufacture of the hollow plates designed as rectangular tubes must have spacers inserted between the flat sections of the hollow plates to be bent together  to prevent the cavity from being dented during processing. For this purpose, round disks are used in the prior art, the throughflow openings have openings. Such round disks are critical in that they possibly slip during the manufacturing process and so their function can no longer maintain as a spacer.

The invention solves the above problem by providing a spacer one of the attachment part attachable to the end face of the hollow plate sections and of this has protruding spacers in the cavity of the hollow plates protrude and in particular have a height that the inner distance of the hollow plates parts essentially corresponds.

Because the spacers according to the invention with their attachment part the front Form the end of the hollow panels and thus be immovably arranged also the protruding spacers automatically immovable, so that at Production no longer has to worry about disruptions due to displaced spacers are.

In a preferred embodiment, the spacers according to the invention protrude of an essentially flat, cross-section formed as an attachment part at least one, preferably two, of the plate corresponding to the hollow plate fork-like protruding spacer strips.

The invention is further illustrated by various embodiments using the accompanying drawings explained in more detail. Show it:

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

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

The convector body 10 has the distribution channel 12 on the front end side, while the distribution channel 17 is attached on the rear end side. The two distribution channels are connected via the connecting tubes 16 to the hollow plates 1 to 4 in the end area. The attachment between the connection tubes 16 and the connection points on the hollow plates can be realized for example by resistance welding.

The rectangular distribution channel 12 is divided into two sections by a horizontally extending web, 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 designed as a continuous rectangular tube.

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

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

A particularly compact embodiment of a convector body 20 with a flow connection on the bottom is shown in FIG. 3. It applies to FIG. 3 and also to FIGS. 4 to 9 that the same reference symbols or reference symbols with identical last digits designate components which correspond to those in FIGS. 1 and 2.

The convector body 20 from FIG. 3, with the exception of the distributor pipe 22, has the same structure as that from FIGS. 1 and 2, and also has the same flow guidance except for this difference. The convector body 20 is a heating element with a flow connection 21 at the bottom. This bottom-side flow connection 21 passes as a tube through the return section 25 of the distribution channel 22 and opens at the top into the flow section 24 , from where the heating medium is then passed on to the uppermost hollow plate 1 . The flow pattern is the same as in the case of the convector body 10 , ie the heating medium flows via the hollow plates 2 , 3 and 4 back into the return section 25 and emerges from the return connection 23 . With the implementation of the flow pipe 28 through the return section 25 , space is saved inside the radiator and it can, for. B. more slats 5 are arranged. The upper connection 21 'in the flow section 24 can either be flanged blind or provided with a vent.

The possible combination of several connections brings a particular advantage variants with themselves.

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, on the connection end face shown on the left, a rectangular distributor channel 32 which runs only over the lower hollow plates 2 , 3 and 4 and which overall forms only one return section. On the rear vent end face shown on the right, a rectangular distribution channel 37 runs over all hollow plates.

The convector body 30 shown here is a heating element that has both the flow connection 38 and the return connection 33 on the bottom side. The flow connection 38 leads upwards as a pipe to a commonly used fitting which distributes the heating medium to the first hollow plate 1 on both sides. Also on the venting end face shown on the right, two connections are provided on the distribution channel 37 , of which the lower connection 39 can be used as a further return connection, while, for example, a ventilation valve can be attached to the upper connection (not shown).

A connection with an integrated valve can also be implemented. The valve forms part of the convector body and is in particular corresponding dressed.

A similar convector heater 40 is shown in FIG. 5. The difference from the convector body 30 from FIG. 4 is that the distributor channel 42 extends over all four hollow plates on the connection end face shown on the left. This distribution channel 42 is also separated below the uppermost hollow plate by a separating device which is not visible here. A pipe leads from the flow connection 48 behind the distribution channel 42 into its upper flow area, while the return connection 43 is provided at the bottom of the distribution channel 42 . As can be seen from the illustration on the right, a return 49 as well as a vent connection can be provided on the opposite end face here as well.

The above embodiment can also be used as a convector heater Center connection can be designed.

An alternative embodiment of a convector heater is now shown in FIG. 6. This radiator comprises (both sides) a divided lower hollow plate having a leading side 4 a and 4 b on the return side. The two representations in FIG. 6 show the same radiator 50 ; the upper illustration is only slightly tilted to make the flow connection 58 and the return connection 59 visible. The flow guidance for this radiator is as follows (see also the arrows): The heating medium reaches the first hollow plate half (flow half) 4 a through the flow connection 58 and is introduced from there via the distributor channel 52 into the upper hollow plates 1 , 2 and 3 , where it flows in the opposite direction, which is indicated on the hollow plate half 4 a. The distribution channel 52 is not divided, ie in this embodiment the role of the separate forward section (see FIG. 1, reference number 14 ) is taken over by the hollow plate half 4 a itself. After flowing through the hollow plates 1 , 2 and 3 , the heating medium enters the rear distribution channel 57 and from there is passed down into the hollow plate half 4 b, which forms a return half. The return port 59 is connected to the hollow plate half 4 b and directs the heating medium out of the radiator.

With this construction it is possible to build a convector with a floor Middle connection.

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

FIG. 8 again shows an embodiment of a heating element 80 which corresponds to the flow guidance of the one shown in FIG. 1. This radiator 80 differs from the radiator 10 shown in FIG. 1 in that tube distributors 82 and 87 are now used instead of the rectangular distributor channels. Furthermore, the return section 82 has a return connection 83 going downward and extends over the three lower hollow plates 2 , 3 and 4 for returning the heating medium. The right view again shows that the rear pipe distributor 87 connects all four hollow plates 1 to 4 to one another.

The embodiment of the heating element 90 according to FIG. 9 corresponds in principle completely to that which was shown in FIG. 8, with the difference that the heating element shown here has only two hollow plates 1 and 2 arranged one above the other on each side. The heating medium flows from the supply connection 91 through the hollow plate 1 and is conducted via the return pipe distributor 97 through the hollow plate 2 back to the return connection 93 , which in turn goes down to the floor.

The principle of the spacers is now shown in FIG . The heating tube spacer arrangement is provided with the reference symbol 100 . It consists of a hollow plate piece 1 which is already bent in shape and the spacers which have an end plate 101 and fork-like spacers 102 . The end plates 101 are adapted or attached to the end faces of the hollow plate 1 during manufacture, so that the fork-like spacers 102 penetrate into the cavity 103 and can serve as spacers for the two side plates of the hollow plate 1 . These spacers can neither slip nor block the flow through the hollow plate 1 .

In Fig. 11 shows another training option for the adjacent hollow plates. The hollow plates 1 , 2 and 3 in the upper illustration and the two hollow plates 1 and 2 in the lower illustration were produced by rolling with the help of profile rollers in the form of closed heating registers. In the embodiment shown here, the adjoining part A has a width of approximately 10 mm when the hollow plate sections are divided by approximately 70 mm.

The Figs. 12 and 13 illustrate a structure of a half-shell Konvektorkör pers. In Fig. 12 the Konvektorkörper in perspective view in various sectional planes I, II and III. The illustration I shows the convector body in half-shell construction with the flow channels 1 to 5 numbered from top to bottom uncut. In view II, the front part of the convector body is cut away in the area of the connections, while 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 it 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 bulged flow channels 1 to 5 , while in the rear half-shell H overflow channels U are provided which pass the heating medium from one flow channel to another at suitable points. These overflow channels U are also designated in FIG. 12, where in section III it can be seen that at the points where the overflow channels U are present, the heating medium can pass from one flow channel into an adjacent flow channel.

By a suitable arrangement of the overflow channels U, the desired flow guidance are generated, in particular a flow control, as before has been described with reference to the previously illustrated embodiments.
