Description

The invention relates to a radiator formed with flat mold tubes, provided with connections for flow, return, venting and emptying, provided for the supply and discharge of the heating medium manifolds and the same in hydraulic connection, can be flowed through by the heating medium heating tubes, wherein the steering and Distribution of the heating medium flow in said heating tubes at least in one of said manifolds at least one of its free interior and flow cross-section partially or completely opaque or the heating medium flow throttling or blocking separating element is arranged and wherein the radiator - instead of in the headers so far at each fixed points permanently installed partitions - with, respective requirements with regard to steering and distribution of the heating medium flow within the radiator according to installable, a manipulating head having separating elements is equipped, d he radiator at those points of the headers, where the arrangement of such a separating element is provided, namely on at least one between the hydraulic connection points to adjacent heating tubes positioned position (s) has a wall of the respective collecting tube passing through insert-opening, in which an interchangeable separating element is used
From the GB 2306215 A a radiator of the type mentioned is known. This radiator has at least one deflecting element at a point connecting in each case two heating pipes in the manifold in the form of a cock with a salable in each position, the flow of heat medium regulating cockerel. A locking and sealing element which can be used in any desired manner in an insertion opening and which does not interfere with the free flow of the heating medium merely for the sealing of the insertion opening in the collecting pipe is not present.

To achieve a good heating capacity of heating medium-flow radiators with one-sided connection, that is, when the flow and return of the heating medium are arranged on one side thereof, which corresponds to the most common type of connection of such radiator, it is necessary that in the radiator an "ordered" water flow sets so that so-called short circuits in the heating medium flow are avoided as possible.

For this purpose, so-called separating plates are installed according to the prior art in the headers so, for example, in one of the manifolds of the radiator in the middle, which for a particular desired, thermally ensure favorable steering of the heating medium flow. But such a radiator is clearly predetermined by connection technology. However, if the customer wants, for example, the connections merely on another side, a new radiator must be made, in which the partition is installed in the manifold on its "other" side. This then means a separate order, delays in delivery time, etc. Particularly annoying is the previously given situation when it comes in the course of an order to errors or errors regarding the connection situation and one with the baffle in the wrong place within one of the manifolds equipped radiator is unusable due to a "false" indication of connection side for a particular intended installation and then may have to wait weeks for the delivery of a new radiator with connection on the "right" side. This problem can of course also occur in radiators with so-called "diagonal" or "riding" connection, where, for example, flow and return "down" are arranged and in which usually no dividers are provided in the manifolds.

The invention has now taken on the task to break the previously given, practically completely inflexible situation and to achieve much more flexible than heretofore manufacturable and usable radiators, namely the fact that it can be ensured that the (the) the flow conditions in the heating tubes determining separating plate (s) in the (the) collecting tube (s) is not fixed from the outset in the (the) same (s) is installed, but depending on the need for heating medium guide within the radiator or in the collecting tube (s) can be installed arbitrarily or just not installed or even at all from the (the) collecting tube (s) can be removed (can).

The invention thus relates to a radiator of the type mentioned, which is characterized

• in that the separating element is flexibly adaptable and replaceably insertable as being flexibly adaptable and replaceable, at least one opening (s), optionally in all of them, having the outer cross section of the respective collecting tube at least partially or completely covering or filling the outer contour of its cross section - Throttle or locking pin or as a the inner cross-section of the headers not or only minimally constricting sealing and sealing plug - the respective insert opening after insertion, by means of sealing tape, pressure and medium tight sealing - is formed,
• wherein it is further provided that the throttle or locking pin with an elongated throttle or locking portion and one with the same, for a pressure and the insertion opening is provided with an internal thread and the closure and fixing section of the throttling or locking pin has a corresponding external thread with which the same can be screwed into the insertion opening, and the at those locations of the radiator, where no throttle or locking pin to be arranged or arranged, to be used, substantially no projecting into the interior of the respective manifold throttling or blocking portion having sealing and sealing stopper, the closure and Having fixing section of the throttle or locking pin according to trained closure and fixing section.

With the present invention, a radiator is created, which is characterized both by its highest flexibility in terms of its connections to the heating medium supply and Abbinden as well as the leadership of the heating medium within the radiator.

As regards the provided in the radiator according to the invention, instead of a fixed separating plate to be used throttling or locking pin itself, an embodiment according to claim 2 is preferred in which the same one provided for a total or at least partial blocking of the heating medium flow in the respective manifold throttle Having - or locking portion and provided for the fluid-tight insertion of this throttle or locking pin in the corresponding insertion opening in the respective manifold closure and fixing.

The claim 3 is shown in a first advantageous embodiment of the throttle and locking pin, wherein its closure and fixing portion is provided with an external thread with which the same is screwed into a corresponding internal thread on the insertion opening in the respective manifold.

Claim 4 discloses an inverse solution to the embodiment according to claim 3, in which the closure and fixing portion is formed in the manner of a hood having an internal thread, which is schraubkooperierbar with a corresponding external thread on a projecting away from the insertion opening in the manifold approach or nozzle.

It is in the - not fixedly arranged separating element in one of the manifolds of the radiator provided - throttle or locking pin even in the case of a desired blocking of the heating medium flow for targeted diversion or deflection of the heating medium flow in predetermined heating pipes per se necessary that by the throttle or locking pin an actually complete barrier of the heating medium flow rate must be achieved, since a limited "leakage flow" practically does not bother.

Accordingly, as can be deduced from claim 5, be provided that the throttle or locking portion of the throttle or locking pin itself has an external screw thread, which is practically only a continuation of the screw thread of its closure and fixing.

In this case, the external thread flanks only touch the inner walls on both sides of the manifold, as the claim 6 can be seen.

However, if no residual or leakage flow in the respective manifold is desired, in particular in the event that the throttle or locking portion of the throttle or locking pin is a conventional cylindrical screw shaft, by - an internal thread corresponding - incisions in the opposite Inner walls of the manifold - a meshing of the thread of the throttle and locking pin in the cut into the manifold inner wall, corresponding "thread strip" can be achieved, for which purpose should be made to the claim 7 .

In the simplest case, as can be deduced from claim 8 , the throttling or locking pin is formed with a standard standard or standard screw thread having screw shank.

In a further advantageous embodiment of the throttling or locking pin for the collecting tube, as can be deduced from claim 9 , whose closing and fixing section are designed in the manner of a medium-tight closing-cooperating bayonet closure with a suitably designed attachment to the insertion opening.

The throttle or locking portion of the new throttle or locking pin can further, as can be seen from claim 10 , be provided with a rigidly around the same materially bonded, about elastically yielding covering, which on the one hand allows this in a row of the lining superficially deformable throttle and locking section through the insertion opening with the internal thread in the respective manifold to "squeeze", after which the coating then "expand" in the manifold again and virtually fluid fluid tight against the inner walls of the manifold nestles.

Concerning the regulation and distribution of the heating medium flow within the radiator can be provided practically for a full blockage of the manifold and diversion or redirection of the heating medium flow in certain heating pipes to form any heating medium partial flows up to a full flow through the manifold by eg the extension length of the throttling or locking portion of the throttling pin or locking pin projecting into the collecting pipe corresponds to the length of the, preferably rectangular shape, internal cross-section of the collecting pipe or is just merely e.g. 80, 50 or 30% of the length of the internal cross-sectional rectangular area corresponds, which then, accordingly, a 20-, 50- or 70% partial flow of the heating medium is allowed in the manifold.

Another regarding partial flow guidance and regulation of the heating medium flexible solution may consist according to claim 11 in an embodiment of the throttling or blocking portion of the throttle or locking pin, which has a shape of a spatula or an elongated plate instead of a solid cylinder shape, wherein the closure and fixing portion is formed in that it allows a rotation of the throttling pin or locking pin, wherein its closing and fixing portion is at least medium-tightly adjustable, so that a full blocking of the flow of the heating medium is achieved when the plate-shaped throttle or locking portion at an angle of 90 ° is aligned "transversely" to the header tube or Heizmediumsströmungs direction or given a maximum flow, when said plate-like portion of the throttle pin is aligned in Heizmediumsströmungs direction, wherein between these two extreme positions each other angular position and Thus, any desired partial flow is adjustable.

This claim further relates to several preferred handling-friendly embodiments of the manipulation head of the new throttling or locking pin.

For all those cases where e.g. for reasons of achieving a respective desired guidance and distribution of the heating medium flow within the radiator, although an insertion opening for introduction of a inventively provided, used as a separating element throttling and locking pin is provided in the narrow side wall of the manifolds of the radiator, but not the arrangement of such a pin is appropriate or desirable, a closure and sealing stopper according to claim 12 is an essential accessory, which advantageously is practically nothing else than a component which corresponds to the throttling or locking pin as described above in various training variants, but without throttle - And locking portion and just essentially formed only with the closure and sealing portion.

Reference to the drawing, the invention is explained in more detail:

The Fig. 1 to 3 show a radiator according to the invention in views from the front, top and from the side, the Fig. 4 a section through the manifold with arranged in the same, provided for the heating medium flow steering throttle or locking pin, the Fig. 5 a section through the manifold with a sealing plug, the Fig. 6 . 7 and 8th each in views from the front three different embodiments or connection variants of the invention equipped radiator, Fig. 9 to 11 a radiator according to the invention in a further configuration, respectively in views from the front, top and from the side, the Fig. 12 . 13 and 14 in each case a further radiator according to the invention with mutually different configurations of its connections and Heating medium guides and finally the FIGS. 15 and 16 a locking or throttle pin in a preferred embodiment for a flexibly selectable setting of the heating medium flow and finally the FIGS. 17 and 18 each in views of the top according to the invention equipped radiator in double tube or plate design.

The in the Fig. 1 to 3 shown, formed with flat-shaped tubes radiator 100 is connected with its right-side, vertical, "first" manifold 2.1 above the heating medium supply Z and below to the heating medium discharge A. In the manifold 2.1 an inflow of the heating medium Hm takes place only in the two upper of the four flat heating tubes 1.1, 1.2, 1.3, 1.4, since the manifold 2.1 in a position between the second and the third heating tube 1.2, 1.3 by means of a laterally in the collecting pipe 2.1 introduced or screwed throttling or locking pin 3 is closed. This throttling or locking pin 3 is screwed into a lateral, the collection tube wall 201 passing through the insertion opening 5 in the upper header section of the favorable for manipulation narrow side, covers practically the entire inner cross-sectional area Qi of the manifold 2.1 and thus prevents further flow of the Heating medium Hm in the lower header pipe section and therefore directs or distributes the heating medium flow Hms fully into the two upper heating pipes 1.1, 1.2.

In the left-side, "second" manifold 2.2 a to the insertion opening 5 in the first manifold 2.1 analog and analogously positioned insertion opening 5 is arranged, in which a the inner cross section Qi of the manifold 2.2 virtually non-constricting sealing and sealing plug 4 is screwed, so of the manifold 2.2 from the effluent from the heating pipes 1.1 and 1.2 heating medium Hm can flow freely into the two lower heating pipes 1.3, 1.4 and finally flow into the below the throttle and locking pin 3 arranged portion of the manifold 2.1 and the same through the right lower connection to the heating medium discharge A can leave.

The 4 and 5 show the two components of the new radiator essential for the invention in detail, in fact, each screwed into the - the narrow side wall passing through - insertion opening 5 in the manifold 2.1.

The Fig. 4 shows how in the - originally a substantially flat-rectangular internal cross-sectional area Qi having - manifold 2.1 a continuously provided with an external screw bolt 3 with its closure and fixing portion 32, which in an internal thread in the region of the insertion opening 5 in the of Side accessible narrow side wall 201 of the manifold 2.1 is screwed and a throttle or locking portion 31 has, which with the outer edges of its thread essentially touches the two in cross section "longer" inner walls 202, 203 of the manifold 2.1 and in this way largely blocks the free cross section Qi of the manifold 2.1 for the flow of the heating medium.

At this point, it should be noted that a full barrier of the inner cross section Qi of the manifold 2.1 can be achieved if in each case in the inner walls 202, 203 on both sides in the form of a merely narrow thread band, the internal thread from the area of the insertion opening 5 is cut further ,

In addition, attention should be drawn to the manipulation knob 33 of the throttling and locking pin 3, which may be e.g. is designed as a thumbwheel.

The Fig. 5 shows the manifold 2.2, but here is in the insertion opening 5 on the narrow side wall 201 merely a screwed to the just described manipulating head 33 analog manipulating head 43 having closure and sealing plug 4 is screwed, which has only one closure and fixing portion 42 which the closure - And fixing section 32 of the in Fig. 4 shown throttling or locking pin 3 corresponds.

At this point it should be noted separately that in all previously and subsequently explained figures on the representation of sealing elements, such as preferably sealing tapes or further sealing rings, sealing compounds od. Like. Is omitted.

The Indian Fig. 6 - With otherwise constant reference numerals meanings - shown radiator 100 is completely similar to those in the Fig. 1 to 3 constructed radiators 100, only this is now left top of the heating medium supply Z and bottom left connected to the heating medium discharge A and the new throttle or locking pin 3 is now in an entirely analogous position to the representations in the Fig. 1 to 3 installed centrally in the "second" manifold 2.2 locks there "centrally" the heating medium flow Hms and deflects him through the two upper heating pipes 1.1, 1.2 now just to the right.

Reversed or symmetrical to the in the Fig. 1 to 3 shown radiator 100 is now the right side, second manifold 2.2 practically freely flowed through, and its insertion opening 5 is sealed medium-tight with a sealing and sealing plug 4.

The Fig. 7 and 8th show - with otherwise constant reference numerals - to the radiators 100 previously shown the same built radiator 100, only has the in Fig. 7 shown radiator 100 so-called "diagonal" connections, so he is here right above the heating medium supply Z and bottom left connected to the heating medium drainage A. The in Fig. 8 Radiator 100 shown has a so-called "riding" connection, that is, it is "on both sides of the bottom" Heating medium supply Z and -A connection A connected.

In both, in the Fig. 7 and 8th Radiators 100 shown are in the embodiment or connection version shown no throttling or locking pin installed in their headers 2.1 and 2.2 and the insert openings 5 in the same are now both with - the heating medium flow Hms practically not obstructing or constricting - Closure and sealing plug 4 closed.

The FIGS. 9, 10 and 11 show - with otherwise constant reference numerals meanings - a radiator 100 equipped according to the invention with "horizontal" headers 2.1, 2.2 and vertical heating tubes 1.1, 1.2, 1.3, 1.4, in which case the lower horizontal "first" manifold 2.1 both to the heating medium supply Z as well as to the heating medium discharge A is connected.

The manifold 2.1 has insertion openings 5 at two locations, in each case in a position between the first and the second vertical heating pipe 1.1, 1.2 and in a position between the third and the fourth heating pipe 1.3, 1.4. In the first of these two insertion openings 5 between the first and second heating tube 1.1, 1.2 here the heating medium flow Hms blocking throttling or locking pin 3 is introduced so that the full heating medium flow Hms through the left, first heating tube 1.1 up in the upper second Collecting tube 2.2 flows in and out of the same through the remaining three vertical heating tubes 1.2, 1.3, 1.4 again flows down to finally flows through the portion of the manifold 2.1 left of the throttle and locking pin 3 without hindrance to the heating medium discharge A, since the second insertion opening. 5 in the position between the third and fourth heating tube 1.3, 1.4 is closed only by means of sealing and sealing stopper 4.

The Fig. 12 shows - with otherwise constant reference numerals meanings - a to that in the FIGS. 9, 10 and 11 shown radiator 100 completely identical built vertical radiator 100, which - as for the connections and the arrangement of the throttle or locking pin 3 and the sealing and sealing plug 4 and the heating medium flows Hms and their leadership or division concerns - the radiator 100 of FIGS. 9, 10 and 11 symmetrically equipped and operated.

These FIGS. 9 to 11 and 12 show that merely a mutual replacement of the throttle pin 3 with the sealing and sealing plug 4 is sufficient to a radiator 100 according to Fig. 12 to have available for one to the heating medium flow direction according to the Fig. 11 Symmetrical flow direction of the heating medium Hm is suitable.

But not only for these two in the Fig. 9 to 11 and 12 shown two types of connection is the new - executed in a completely identical design - Radiator 100 suitable, which in positions between the first and second heating tube 1.1, 1.2 and between the third and fourth heating tube 1.3, 2.4 insertion openings 5, as the Fig. 13 and 14 - with otherwise identical reference sign meanings - show:

The Fig. 13 shows a radiator according to the Fig. 11 and 12 just built radiator 100, only he is with his headers 2.2, 2.1 this time right up to the heating medium supply Z and bottom left connected to the heating medium discharge A, thus has a "diagonal" leadership of the heating medium Hm, here two insertion openings 5 are closed in the lower manifold 2.1 by means of sealing and sealing stopper 4. It goes without saying that these radiators 100 are equally useful, whether they are now connected to the left of the heating medium supply Z and right to the heating medium discharge A, or vice versa.

The possibilities of flexible adaptation to the respective connection conditions go even further, like the Fig. 14 shows, according to which a radiator 100 is connected to the same type and the same equipment with two plugs 4 - now "one-sided" - right above the heating medium supply Z and right below to the heating means discharge A.

Also, this radiator 100 would allow without any change a left-side heating medium feed and of course a swap of heating medium supply Z and -A derivative.

The Fig. 15a and b such as Fig. 16a and b show - with otherwise constant reference numerals meanings - a particularly advantageous embodiment of a throttle or locking pin 3 according to the invention, depending on its "oblique or Nichtschräg" position in the manifold 2.1 for throttling the heating medium flow Hms in any strength, ie is also suitable for a virtually full blocking thereof.

This throttle or locking pin 3 is originally formed with a conventional cylindrical threaded bolt. This is in its closure and fixing section 32 "intact" and there has a normal external screw thread, with which the throttle or locking pin 3 is screwed into an insertion opening 5 in the wall 201 of a manifold 2.1. On the other hand, 31 two diametrical cylinder segments are "cut out" of the bolt in the throttle or locking section, so that only an elongated plate-like residual body with a width of the inner width wi of the manifold 2.1 corresponding plate width bp and a much smaller plate thickness dp remains, which here in one piece is formed with the sealing and sealing portion 32. By turning the manipulation head 33 can this Plate body of the throttle or locking pin 3 in a the inner cross section Qi of the manifold 2.1 opaque or filling position transversely to the flow direction of the heating medium and the flow are brought blocking, as they Fig. 15b shows.

From this blocking position can be brought about continuously adjustable angular positions therebetween ultimately this plate body by means of Manipulierkopf 33 in a - ensuring a maximum flow of the heating medium - position in which this plate body is aligned in the direction of the heating medium flow Hms or collection tube longitudinal direction.

If so far in the Fig. 1 to 16 only radiators with heating pipes or hot plates 1.1 to 1.4 shown, which are arranged only on one side of the headers 2.1, 2.2, ie the front side, the invention is by no means limited to this one main embodiment, but it extends in the same way on Double-tube or radiator 100, as shown in schematic views from above in the FIGS. 17 and 18 - are shown with otherwise constant reference sign meanings -

In the in the Fig. 17 shown double-plate radiator 100 are between two series of heating pipes or plates, of which each of the top 1.1 are visible, the two arranged in hydraulic composite manifolds 2.1, 2.2, in which case the right-side header 2.1, for example, each top and bottom can be connected to the heating medium supply and discharge. At a respectively provided for a blocking or diversion of the heating medium flow point a lateral insertion opening 5 is provided in this manifold 2.1, in which a throttle or locking pin 3 is used, that is in particular screwed.

In the right-hand manifold 2.2 is, at a point where the insertion of a throttle or locking pin may be necessary or desirable, also an insertion opening 5 is arranged, in which here only a sealing and sealing plug 4 used, that is in particular screwed.

In the double-plate heater 100, of which the Fig. 18 only the right side shows, is connected to a connected to the heating medium supply Z T-tube - each for each of the two series of heating tubes own manifold 2.1, also connected respectively with insertion openings 5, in one example here, the flow of the heating medium Hm in the "upper" manifold 2.1 blocking throttling or locking pin 3 and in the "lower" - collecting 2.1 a flow of the heating medium Hm not obstructing sealing and sealing plug 4 is used.
