An Independent claim for a spacer for contruction of a hollow horizontal panel for a heating or cooling device is also included.

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 certain Direction (usually up or down) and thereby one 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.

It is the object of the present invention to provide a heating or Heat sink design so that it is high functionality and reliable optimized heat and cold transfer allowed. In particular, flexible Installation options created and a visually appealing design enables become.

This object is achieved by the characterizing part of the claim 1 listed features solved. Those affecting the heating or cooling element Subclaims describe preferred embodiments of the invention.

The inventive design of the distribution of the heating or cooling medium in the Convector body advantageously offers the possibility of the flow and return connections depending on your preference at different points of the radiator or heat sink lay. The arrangement of separate distribution channels, as proposed according to the invention flexibility increases the design options for one Convector body. 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 according to the invention then made available 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, the throughflow openings, are used in the prior art exhibit. 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 plate 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.

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

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

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

The rectangular distribution channel 12 is through a horizontal Web divided into two sections, namely a forward section 14 and a return section 15. This can be clearly seen in the cut-out area of FIG. 1. The distribution channel 17, however, is designed as a continuous rectangular tube.

Located in the lower region of the distribution channel 12, namely in the return section 15 the return connection 13 of the convector body, while the forward section 14 has the flow connection 11.

When performing heating medium by the one shown in Figs. 1 and 2 Convector body accordingly results in the following flow sequence, which is shown in FIG Arrows on the hollow plates is recorded. From the flow port 11 that reaches Heating medium the flow section 14 and flows through the connecting tubes 16 in the top first hollow plate 1 (on both sides of the convector body) and from here again in the rectangular distribution channel 17. The distribution channel 17 becomes Heating medium 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 exits the return port 13.

A particularly compact embodiment of a convector body 20 with a bottom flow connection is shown in Fig. 3. For Fig. 3 and beyond 4 to 9 also applies that the same reference numerals or reference numerals with Identical last digits denote components that correspond to those in FIGS. 1 and 2.

The convector body 20 from FIG. 3 has the same with the exception of the distributor pipe 22 Structure on like that of FIGS. 1 and 2, and he also has up to this Difference the same flow. The convector body 20 is a heater with a flow connection 21 at the bottom. This flow connection 21 at the bottom passes as a tube through the return section 25 of the distribution channel 22 and opens at the top in the flow section 24, from where the heating medium then turns is passed on to the top hollow plate 1. The flow is in the further the same as the convector body 10, i.e. the heating medium flows over the hollow plates 2, 3 and 4 back into the return section 25 and exits the return port 23 out. With the passage of the feed pipe 28 through the return section 25 space is saved inside the radiator and z. B. more slats 5 are arranged. The upper port 21 'in the lead section 24 can either be flanged blind or provided with a vent.

The summary possible according to the invention brings a particular advantage several connection variants with itself.

Fig. 4 shows a front and a rear end perspective view a convector body 30 according to a third embodiment. This convector body 30 has on the connection end face shown on the left only via the lower hollow plates 2, 3 and 4 extending rectangular distribution channel 32 on the overall forms only one return section. On the rear shown on the right Vent end face runs a rectangular distribution channel 37 over all Hollow plates.

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

According to the invention, a connection with an integrated valve can also be implemented become. The valve forms part of the convector body and is in particular dressed accordingly.

A similar convector heater 40 is shown in FIG. 5. The difference to the convector body 30 from Fig. 4 is that on the connection face shown on the left the distribution channel 42 extends over all four hollow plates. This one too Distribution channel 42 is below the top hollow plate by a not visible here Separating device separated. A pipe leads from the supply connection 48 behind the distribution channel 42 in the upper flow area, while the return port 43 below is provided on the distribution channel 42. As can be seen from the illustration on the right, here again on the opposite end face both a return 49 below and a vent connection can also be provided at the top.

The above embodiment can also be used as a convector radiator with a center connection be designed.

6 shows an alternative embodiment of an inventive one Convector radiator shown. This radiator has a split (on both sides) lower hollow plate with a flow side 4a and a return side 4b. The two 6 shows the same radiator 50; is the top illustration only tilted a little to the flow connection 58 and the return connection 59 make visible. The flow of this radiator is as follows (See also the arrows): Through the flow connection 58, the heating medium gets into the first hollow plate half (forward half) 4a and is from there via the distribution channel 52 introduced into the upper hollow plates 1, 2 and 3, where it is opposite to the direction flows, which is indicated on the hollow plate half 4a. The distribution channel 52 is not divided, i.e. in this embodiment, the role of the separate lead section (See Fig. 1, reference numeral 14) 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 distribution channel 57 and from there down into the hollow plate half 4b passed, which forms a return half. The return port 59 is with the Hollow plate half 4b connected and guides the heating medium out of the radiator out.

With this construction, it is possible to use a convector according to the invention with a Bottom center connection to be provided.

7 corresponds, as far as the basic flow guidance is concerned, to that in FIG. 6 illustrated embodiment. The radiator 60 according to FIG. 7 is, however Radiator with three heating plates, each consisting of continuous hollow plates 1, 2 and 3 are formed. The lower hollow plate of the front heating plate is in turn Forward or return halves 4a and 4b divided so that the already with reference to FIG. 6th discussed flow is achieved. In contrast to the radiator 50, the radiator has 60 but instead of the rectangular distribution channels, pipe manifolds 62 and 67 with usual fittings. This radiator 60 also has the bottom connections 68 (flow) and 69 (rewind).

FIG. 8 again shows an embodiment of a radiator 80 which relates to the flow guidance corresponds to that shown in FIG. 1. This radiator 80 differs from the radiator 10 shown in Fig. 1 in that pipe distributors 82 and 87 are now used instead of the rectangular distribution channels become. Furthermore, the return section 82 has a downward going Return port 83 and extends to return the heating medium over the three lower hollow plates 2, 3 and 4. In the right view you can see that the rear manifold 87 connects all four hollow plates 1 to 4 together.

The embodiment of the radiator 90 according to FIG. 9 corresponds in principle completely of that shown in Fig. 8, with the difference that the one shown here Radiators shown only two hollow plates 1 and 2 arranged one above the other on each side. The heating medium flows from the flow connection 91 through the Hollow plate 1 and is via the return pipe manifold 97 through the hollow plate 2nd returned to the return port 93, which in turn down to the floor goes off.

The principle of spacers according to the invention is now shown in FIG. 10. The The heating tube spacer arrangement is provided with the reference symbol 100. she consists from an already bent hollow plate piece 1 and the spacers that have an end plate 101 and fork-like spacers 102. The end plates 101 are adapted to the end faces of the hollow plate 1 during manufacture or attached so that the fork-like spacers 102 in the cavity 103rd penetrate and as a spacer for the two side plates of the hollow plate 1 can serve. These distances can neither slip nor block them the flow through the hollow plate 1.

11 shows a further training option for the adjacent ones 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 made by rolling with the help of profile rolls made in the form of closed heating registers. The one shown here The adjacent part A has an embodiment when the hollow plate sections are divided of about 70 mm, a width of about 10 mm.

FIGS. 12 and 13 illustrate a half-shell structure of a convector body. In Fig. 12 the convector body is in perspective view in different Section planes I, II and III shown. The illustration I shows the convector body in Half-shell construction with the flow channels numbered from top to bottom 1 up to 5 uncut. In view II, the front part of the convector body is in the Area of the connections cut away, while the illustration III one more shows the convector body cut further back.

In conjunction with the unfolded view of such one shown in FIG. 13 Half-shell convector body is now clear that this has hot plates that are Assemble from 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 on, 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, with III it can be seen that at the points where the overflow channels U are present, the Transfer heating medium from one flow channel to an adjacent flow channel can.

The desired flow guidance can be achieved by a suitable arrangement of the overflow channels U. are generated, in particular a flow guide, as before has been described with reference to the previously illustrated embodiments.
