Description

The invention relates to a radiator having at least a first heating element and at least one second heating element, at least one flow connection and at least one return connection and Abstandhalte- and / or connecting elements between the heating elements, and a retrofittable shut-off and release device for retrofitting in a radiator for shutting off and releasing the overflow of heating medium from the at least one first heating element to the at least one second heating element of the heating element, wherein spacer elements and / or connecting elements are provided between the heating elements of the heating element.

Radiators with at least two heating elements, in particular heating plates, are known in the art. These have a flow connection for supplying heating medium to the radiator and a return connection for discharging heating medium from the radiator. Spacer and / or connecting elements are arranged between the heating elements, which serve to secure the heating elements to each other, to maintain a distance between the heating elements and to allow heating medium to flow from one heating element to the other. In particular, in flat radiators, it is known, via a special leadership of the heating medium, preferably heated water, first the front to a living space executed heating element with heating medium and only then the second rear heating element directed away from the housing to be heated, usually directed towards a room wall is to flow through. In this case, all heating elements, such as heating plates, the radiator of the heating medium in the circuit between the heat source, usually a boiler, and heat exchangers, ie the radiator flows through. Most T-shaped Abstandhalte- and / or connecting elements are arranged between two adjacent heating elements to keep them at a distance and to secure them together. Depending on the configuration, they serve only as a spacer between the two heating elements or in addition to the management of heating medium from one to the other heating element, and also supply and return can be connected to the Abstandhalte- and / or connecting elements. Further, in a sleeve of one or more of the spacer and / or connecting elements, a valve, such as a thermostatic valve or a vent valve, are inserted and received therein.

It is also known to provide radiators already in their manufacture with a device for separately controlling the supply of heating medium to the at least two heating elements. For example, this describes DE 10 2007 036 141 A1 a flat radiator for a partial load operation, which has a flow connection, a return connection, a first through-flow and the space to be heated facing the heating plate and at least one further flowed through and arranged behind the heating plate. Between the upper and lower end portions of the heating plates connecting pieces are arranged, which is passed through a selective arrangement of shut-off devices in at least one of the connecting pieces, the first heating plate in front of the other heating plates substantially uniformly. For controlling the total mass flow of heating medium, a radiator valve is provided and another integrated in one of the upper connecting pieces, with which the mass flow of the heating medium is passed into the rear heating plate via an overflow connection.

Also the DE 10 2010 010 541 A1 discloses a radiator having at least two heating elements, at least one flow and at least one return and at least one means for separately controlling the supply of heating medium to the at least two heating elements, the device comprising a setting or valve means for controlling the supply of heating medium to the first Heating element and the at least one further heating element. The adjusting or valve device is designed so that in part-load operation substantially no heating medium flows into the at least one further heating element and further substantially no heating medium from the first heating element into the at least one further heating element.

All radiators mentioned above are already provided ex works, ie during their manufacture, with a corresponding device for separately controlling the supply of heating medium to the at least two heating elements. However, there are a large number of radiators that are already installed in buildings and in which it would also be useful to provide a way that allows a targeted supply of heating medium to the at least two heating elements, ie a separate supply of heating medium to the one Space-facing heating element and the at least one directed toward the room wall heating element, so the heating element to be heated facing the heating medium to be applied more strongly than that of this away to save energy, as often a partial load operation of the radiator will be sufficient to the room pleasant to heat. In the conventional radiators, however, such can not be provided because there is a lack of means for selectively controlling the supply of heating medium to the at least two heating elements and such can not be retrofitted in a simple manner, but rather extensive conversion measures would be required with respect to the radiator.

The present invention is therefore based on the object to provide a simple and effective way to convert a conventional radiator in an asymmetrically controllable radiator, so provide a separate controllability of the supply of heating medium to the at least two heating elements.

The object is achieved for a radiator according to the preamble of claim 1, characterized in that provided to provide an asymmetric control of the heating elements can be retrofitted into the radiator shut-off and release device, in and / or at least one of the spacer and / or connecting elements and / or in a medium inlet opening of the at least one second heating element and / or in a medium outlet opening of the at least one first heating element and / or in one of the heating elements is inserted or added, wherein the retrofittable shut-off and release device comprises at least one adjustable device for partial or completely allowing or preventing the passage of heating medium into the at least one second heating element. For a retrofittable shut-off and release device for retrofitting in a radiator for shutting off and releasing the access of heating medium to at least one heating element of the radiator, wherein provided between the heating elements of the radiator Abstandhalte- and / or connecting elements, the object is achieved in that the Shut-off and release device comprises at least one adjustable device. Further developments of the invention are defined in the dependent claims.

This creates the possibility of retrofitting a shut-off and release device in an existing radiator, which is inserted either in one of the spacer and / or connecting elements between the heating elements or at least intervenes there or directly into one of the medium inlet and / or -auslassöffnungen in the second heating element is inserted in order to specifically enable or prevent the inflow of heating medium into it. Another possibility is to use the retrofittable shut-off and release device in one of the medium outlet of the first heating element, which faces a room to selectively allow or prevent a passage of heating medium flowed into the first heating element in the second, facing a room wall heating element or to allow a partial flow to flow from the first heating element into the second heating element. The adjustable device of the shut-off and release device may be a temperature-dependent opening and closing enabling device, as well as a flow-dependent adjustable, but also be a manually operable device.

The adjustable device can advantageously be designed in the form of a servomotor with displaceable piston. The servo motor can be inserted into a sleeve of one of the first and the second heating element spaced from each other and these interconnecting spacer and connecting elements, in particular screwed. By the axial displacement or displacement of the piston, the passage of heating medium from the first heating element into the second heating element can be prevented. In order to prevent a passage of heating medium elsewhere in the radiator from the first heating element into the second heating element, sealing elements are provided in the other spacer and connecting elements which are arranged between and connected to the heating elements. In an existing or finished radiator sealing elements can be retrofitted. The sealing elements advantageously have no overflow opening in order to prevent leakage current from the first heating element into the second heating element. In particular, the servomotor with displaceable or axially adjustable piston, if necessary. Also radially adjustable, so rotatable piston to spend in this possibly provided lateral openings for the passage of medium in a sealed and in an open position, laterally above or below be arranged on a radiator on the Heizmediumvorlauf and Heizmediumrücklauf opposite side. The Abstandhalte- and connecting elements, in the lateral sleeve of the adjusting motor is arranged with adjustable piston, in particular T-shaped and formed as a flow press or hybrid part, wherein a channel separation and / or a piston sealing surface for the adjustable piston can be formed or arranged therein / can ,

The servo motor can be controlled and / or regulated manually or comprise an automatic control or regulating device integrated therein, which is dependent on the detected room temperature of the room in which the radiator is arranged, and / or time-dependent, in particular also seasonal, the Overflow of heating medium from the first heating element in the second heating element permits or inhibits by appropriately adjusting the piston. In order to make a time-dependent control or control, a timer or a corresponding device can be integrated into the servomotor or connected to this. To enable a seasonal dependency, a calendar can be stored for the controller.

The servomotor can also be provided with an interface device in a heating billing, for example. In multi-party houses for determining the heating cost distribution to the individual radiator or to transmit the information, how often and how long the second heating element has been switched to a detection device for detecting or determining the heating cost distribution. Connected to the servomotor itself may be means for detecting the respective position of the piston occupied over a period of time and thus the flow of heating medium into the second heating element in order to be able to transmit this data via the interface device to the heating cost distribution detection device.

The servomotor can be controlled electrically according to an underlying programming or alternatively manually, as well as a combination of both is possible, especially in the event that an electrical control due to power failure is not possible.

The retrofittable shut-off and release device may also be formed in the form of a ballast with adjustable device in training as an actuator for releasing and shutting off the flow connection through the Vorschaltgarnitur. The Vorschaltgarnitur can be arranged, for example, to the respective sleeves of two adjacent spacer and connecting elements between the at least two heating elements, in particular on a radiator with respect to the upper and arranged at one underneath, ie lower, spacer and connecting element. The Vorschaltgarnitur advantageously includes corresponding adapter elements which engage in the sleeves or can be connected to them. Between the adapter elements, a pipe connection with the actuator is advantageously arranged. The actuator can be, for example, a thermal capsule or the like, ie a thermal actuator or else an electrical and / or manually operable, in particular in the form of a hand lever. The actuator releases the flow connection between the two adapter elements and thus through the Vorschaltgarnitur or prevents them. If, in particular, a thermal actuator is provided, the mass flow of heating medium from the first heating element into the second heating element can be reduced or completely interrupted with a corresponding increase in the room temperature. In order to ensure that heating medium in each case does not flow directly from the first heating element into the second heating element, but via the Vorschaltgarnitur advantageous sealing elements or sealing discs are arranged at the locations through which no heating medium to flow, for example. In the area lower opening of the first heating element and in the region of an upper opening of the second heating element, so that heating medium from the upper opening of the first heating element (all related to the existing space-mounted radiator) through the Vorschaltgarnitur through the lower opening of the second heating element in this flow can.

In the field of adapter elements of Vorschaltgarnitur an adaptation to the respective design of the sleeves or spacer and connecting elements of the existing radiator can be done via banjo bolts and sealing rings. Another embodiment of adapter elements is possible here.

The Vorschaltgarnitur can also be formed, for example, as an injection molded part and in particular provided with a device for enabling a length compensation, which is integrated in this. As a result, a problem-free adaptation to different radiator sizes or distances between the spacer and connecting elements, at the sleeves of the Vorschaltgarnitur to attack, possible.

The actuator can, as already mentioned, not only be temperature-dependent and / or electrically adjusted automatically, but also manually, for example. Via a hand lever. About a temperature specification, an indirect control of Vorschaltgarnitur done.

Another possibility of forming the retrofittable shut-off and release device is the provision of at least one sealing element which is provided with at least one bimetal insert. The sealing element can in particular be inserted into a spacer and / or connecting element at a point at which a passage of heating medium from the first heating element into the second heating element is to be made possible through the corresponding spacer and connecting element. The sealing element may be formed, for example, as a sealing washer, in particular as a sealing disc made of silicone. This has a bimetal. In particular, the bimetallic insert is arranged in or on the sealing element such that in the cold state, a passage opening through the sealing element and / or the bimetallic insert is opened. This makes it possible to flow through the at least two heating elements with heating medium. For example, the sealing element can be provided in the spacer and / or connecting element, in which a thermostatic valve is arranged and in which the heating medium from the Heizmediumvorlauf first enters. By heating medium, which flows through the sealing element, and the heat transfer associated therewith, it may for an at least partial closure of the passage opening in the sealing element or bimetallic insert, for example come by lowering a closure element by means of the bimetal in the through hole or by expanding a dazzle-like bimetallic insert, so that its inner through hole always closes when heated. In addition to a heat transfer through the heating medium can be transmitted through the outer wall of the spacer and / or connecting element heat in the interior and thus on the bimetallic insert of the sealing element. With increasing heating of the radiator or the two heating elements automatically heats between them arranged respective Abstandhalte- and / or connecting element, so that also the bimetallic insert can be influenced to the effect that closes an inner passage opening of this and / or the sealing element , With increasing heating, the inner passage opening is closed by the sealing element, by the closure element, in particular a piston and / or a diaphragm more and more, so that a passage of heating medium in the second heating element is increasingly prevented, thus the first heating element is prioritized flows with heating medium ,

To prevent passage of heating medium from the first heating element into the second heating element, sealing disks are again arranged in at least part of the other spacer and / or connecting elements, in particular without an overflow opening or to allow venting of the second heating element with an overflow opening, however is low, that an overflow of heating medium from the first heating element is prevented in the second heating element as far as possible.

Especially when forming a sealing element with bimetallic insert, which is designed in the form of a segment diaphragm, so that the bimetal is annular in the interior of the sealing element and an internal passage opening during expansion can at least partially close, is an arrangement of such a sealing element, in particular in a medium inlet opening of the second heating element , in particular in the lower region of the radiator on the side of the radiator opposite to a lateral flow and return connection. The segment diaphragm only fails after thorough heating of the first heating element and also allows heating medium to flow into the second heating element, which is usually located in a space in the back, in order to heat it. With respect to the sealing element, heating and heat transfer from the outside through the wall of the sealing element takes place inwards towards the bimetal insert, since otherwise the segment diaphragm would always be open. Advantageously, the sealing element is arranged in the spacer and / or connecting element, which is arranged at the bottom and opposite to a thermostatic valve with respect to the radiator. In the region of the thermostatic valve, the flow connection to the second heating element is prevented by arranging a sealing element without an overflow opening.

Another possibility of forming the retrofittable shut-off and release device is the provision of a sealing element with slotted membrane insert. Such a sealing element is also in several parts, as is the above-described sealing element with a bimetal insert. It is in turn an existing example of silicone outer sealing body is provided which can be sealingly inserted into the spacer and / or connecting element or an opening of the first and / or second heating element. Inside, at least one slotted membrane is arranged. The sealing element is arranged in particular in the spacer and connecting element, which is provided with the flow connection of the radiator and with a thermostatic valve. If the thermostatic valve is fully opened, with high heat demand, there is a high mass flow of heating medium, which flows into the spacer and connecting element and from this first into the first heating element. Due to the high mass flow, the slotted membrane is opened and the heating medium flow into the second heating element through the sealing element with the slotted membrane. If the room temperature rises or the mass flow of heating medium is subsequently reduced again by adjusting the thermostatic valve, the membrane automatically closes again because of its inherent rigidity, so that the mass flow of heating medium which can flow into the second heating element is reduced or, depending on the design the membrane is completely interrupted. It can therefore be provided an adjustment and / or an independent scheme. In principle, the slotted membrane can be formed so that the second heating element can always be supplied with a minimum mass flow, so at least a portion of the slits of the membrane always allow a passage of a minimum amount of heating medium. Sealing elements, in particular those with bimetallic insert, such as in the form of a segmented panel, or those with slotted membrane or membrane insert can be used with the aid of a special tool in a distance and / or connecting element.

As with the other embodiments of the sealing elements is an overflow of heating medium from the first heating element in the second heating element by arranging corresponding sealing elements or sealing disks in the other Abstandshalte- and / or Prevents connecting elements, in particular the spacer and / or connecting elements, which are opposite to the one provided with the thermostatic valve with respect to the radiator. In order to enable a venting of the second heating element, in turn, a sealing element, in particular a sealing disc, provided with overflow.

Another possibility of forming the retrofittable shut-off and release device is the provision of an element or support member with through holes for the penetration and passage of heating medium, wherein at least one of the through holes, an exit or outflow, is covered by a magnetizable or magnetic membrane , wherein the membrane can be lifted by a magnet from the discharge opening. Such an element is advantageously arranged in the first heating element in the region of a medium outlet opening in the spacer and connecting element connected there, so it is prepared in the heating element in the heating element. This makes it possible to allow heating medium to flow into the interior of the element. An outflow into the spacer and connecting element, however, is possible only when lifting the membrane from the corresponding outflow opening. In order to be able to lift the membrane from the outflow opening, it is provided with a magnetic or magnetizable, in particular metallic, material. On the outside, in particular turned to the room in which the radiator is arranged, a guide slot can be provided on the first heating element, which is provided with a magnet. By moving the magnet in the guide slot and correspondingly arranging it at a location on the outside of the first heating element, in which the membrane provided with the magnetic material is arranged inside, it can be lifted off the outlet opening, since the magnetic, in particular metallic, material passes through attracted to the magnet and accordingly the membrane is lifted from the outlet opening. As an alternative to providing a lift-off membrane, it is also possible to provide a flap-shaped element, which is articulated in particular in the area of the outflow opening, which can also be actuated from the outside via the magnet, ie the flap away from the outflow opening and after removal of the magnet to close off the Outflow opening can be pivoted back to this.

The guide slot can be glued on the outside of the first heating element, for example, clipped or plugged. Other types of connections can be provided here. The guided in the guide slot magnet can be moved manually manually, but possibly also via a drive means to open the outflow opening for the passage of heating medium from the first heating element into the second heating element into or close again after removal of the magnet.

1 shows a perspective view of an inventively equipped radiator 1 with a first heating element directed into a room 10 and a second heating element directed towards a room wall 11 , Between the two approximately rectangular in plan view heating elements 10 . 11 are each in the range of their corners between these spacers and fasteners 12 . 13 . 14 . 15 arranged. To connect between the heating elements 10 . 11 and the Abstandhalte- and / or connecting elements 12 to 15 be able to provide, if there are no sealing elements inserted, have the two heating elements 10 . 11 four openings each on the two sides facing each other 16 . 17 on. These openings 101 to 104 respectively. 111 to 114 are in 1 also indicated.

The spacer and connecting element 12 is with a riser 20 connected by a flow connection 2 in the direction of the spacer and connecting element 12 rises. Coupled to the flow connection, but not connected to the flow, is a return connection 3 that with the spacer and connector 15 is in flow communication. In this embodiment of the radiator 1 Thus, a lateral connection for flow and return of the heating medium is provided on the radiator.

As 1 can be further removed, is on the existing and installed in a room or mounted radiator 1 for enabling a serial control of the two heating elements 10 . 11 a shut-off and release device 4 in the form of a servomotor 40 that with an adjustable piston 41 is equipped, retrofitted. The piston can in the longitudinal direction, ie axially, by the servomotor 40 moved to the case 42 the shut-off and release device 4 retracted and moved out of this again to the passage of heating medium from the first heating element 10 in the second heating element 11 either in the area of the spacer and connecting element 14 or optionally the spacer and connecting element 13 to allow or prevent. The attachment possibility of the servomotor 40 with adjustable piston 41 or both enclosing housing 42 the shut-off and release device 4 at the spacer and connecting element 13 is indicated by dashed lines, since the attachment to the spacer and connecting element 14 in the 1 is actually provided, therefore by direct arrangement on the corresponding sleeve 140 the spacer and connecting element 14 is shown. When attached to the spacer and connecting element 13 will connect in the area of the sleeve 130 provided, in each case, so when attaching to the sleeve 130 or the sleeve 140 each of the adjustable piston 41 the shut-off and release device 4 through the servomotor 40 actuated by the sleeve 130 respectively. 140 into the interior of the spacer and connector 13 respectively. 14 engages and releases or shuts off a flow path for heating medium. As 2 can be taken better, has the adjustable piston 41 one liftable from a piston sealing surface end-mounted piston plate 43 to allow passage of heating medium from the first heating element 10 through the spacer and connecting element 14 in the second heating element 11 to enable. To the piston 41 may also have a side window 44 be provided and either displaced axially so that a passage of heating medium from the first heating element to the second heating element through the window is enabled or disabled. Furthermore, it is possible to adjust the piston by turning or rotating so that the window 44 is either open to the passage of heating medium or is rotated into a closed position, so that no passage of heating medium from the first heating element 10 in the second heating element 11 is possible.

Heating medium thus flows from the flow connection 2 over the riser 20 to the first spacer and connecting element 12 , through this into the opening 101 of the first heating element 10 , through this to the opening 103 in the spacer and connecting element 14 into it. If the adjustable piston 41 , controlled by the servomotor 40 , a passage opening through the spacer and connecting element 14 Keeps open, the heating medium in the second heating element 11 flow. To prevent the heating medium also through the spacer and connecting elements 13 and 15 or directly via the spacer and connecting element 12 in the second heating element 11 gets into it becomes one corresponding sealing washer 5 provided there without overflow, as in 1 in the area of the opening 104 in the spacer and connecting element 15 shown. In the area of the spacer and connecting element 12 becomes a direct inflow of heating medium in the second heating element 11 through the opening 111 also by providing a corresponding sealing washer 5 prevented without overflow or other suitable measures, if necessary, by appropriately forming a thermostatic valve 6 that in the thimble 120 the spacer and connecting element 12 inserted and in 1 also shown. In the spacer and connecting element 13 is when the servomotor 40 or the shut-off and release device 4 at the bottom of the radiator, so at the spacer and connecting element 14 , mounted, is a gasket 7 arranged with overflow.

The servomotor or the housing 42 with servomotor 40 and pistons 41 can thus be retrofitted in the lateral sleeve 140 respectively. 130 of the spacer element 14 respectively. 13 screwed or otherwise inserted there. Advantageously, the servo motor is battery operated, so that no further wiring of this is required. The respective spacer and / or connecting element 13 respectively. 14 in its respective sleeve 130 respectively. 140 The piston 41 engages can be formed as extrusions or hybrid part, in particular also have a channel separation and / or a piston sealing surface, with which the piston cooperates to open and a closed position in view of the possibility of a flow of heating medium through the respective Abstandshalte- and connecting element 13 respectively. 14 provided. For example, a partially spherical spacer and connecting element can be provided with a silicone flap or a piston, wherein a closed position can be adjusted by turning. Further, formation without channel separation is possible with a piston of a silicone material or a material having similar properties.

For controlling or regulating the servomotor 40 a control or regulating device can be provided which carries out a control as a function of the room temperature. For this purpose, a measuring device for detecting the room temperature is provided, on whose data such a control device for the servomotor can access. Furthermore, a timer and / or a stored calendar can be provided to make a time or season-dependent control of the servomotor. All these data can possibly be transmitted wirelessly to a corresponding control device of the servo motor and / or the corresponding control device for the servomotor can wirelessly transmit the control data to the servo motor.

Furthermore, an interface device can be provided for a heating cost detection device, wherein the times are detected, in which also the second heating element 11 is acted upon with heating medium to capture this correctly in the heating cost distribution, for example, in an apartment building in the settlement of heating costs. Via the interface device, the data exchange takes place in such a way that the heat output of an on or off second or with respect to the room rear heating element is correctly taken into account by the heat cost allocator. This is not possible in previous hydraulic and thermal solutions for asymmetrically driven radiators.

Instead of an electrical control via the servomotor can also be a manual actuation of the piston 41 and / or the servomotor 40 respectively. This is in 1 and 2 but not shown.

3 shows a further embodiment of the shut-off and release device 4 , here in the form of a Vorschaltgarnitur 45 , This is to the two spacer and connecting elements 13 . 14 via two adapter elements 46 . 47 4 affiliated and fluidly connected with these. The ballast 45 further comprises between the two adapter elements 46 . 47 a pipe connector 48 , in whose longitudinal extent an actuator 49 is arranged. The actuator may for example be a thermal, so temperature-sensitive actuator, such as a thermal capsule, and / or an electric actuator and / or a manually operable actuator, such as a hand lever. By actuating the actuator 49 the passage of heating medium through the pipe connector 48 controlled or possibly also regulated. As a result, therefore, the supply of the second heating element 11 controlled with heating medium, wherein the heating medium, as in the embodiment according to 1 , via the flow connection 2 , the riser 20 and the spacer and connecting element 12 first in the first heating element 10 passes and from this through the opening 102 in the spacer and connecting element 13 and from there to the ballast 45 into it. Depending on the position of the actuator 49 it gets into the spacer and connecting element 14 and from there into the second heating element 11 into it. A return flow of heating medium into the return connection 3 is through both the opening 104 in the first heating element 10 as well as 114 in the second heating element 11 and subsequently through the spacer and connector 15 through into the return port 3 possible. When using a thermal actuator 49 , but also in providing another education of the actuator 49 can with gradual heating of the room, so increase the room temperature, the mass flow of heating medium through the Vorschaltgarnitur 45 through into the second heating element 11 reduced or completely interrupted. The ballast 45 can be formed in one piece as an injection molded part and comprise a length compensation device to a length adjustment to different distances of the sleeves 130 . 140 the spacer and connecting elements 13 . 14 with different radiators 1 to be able to make. To prevent the inflow of heating medium through the opening 103 in the spacer and connecting element 14 there is a gasket 5 without overflow and in the spacer and connecting element 13 in front of or in the opening 112 of the second heating element 11 a sealing washer 7 provided with overflow. The latter serves to remove air from the second heating element 11 to be able to escape, so to allow venting. The sealing washers 5 and 7 are also inserted later in the radiator.

The ballast can with its two adapter elements 46 . 47 in the field of sleeves 130 . 140 for example, be added via hollow screw and sealing rings and at the same time be adjusted accordingly. The in the area of the sleeve 130 used hollow screw can include a vent to vent the radiator 1 to enable. The ballast 45 is on the one in the sleeve 120 the spacer and connecting element 12 inserted thermostatic valve 6 opposite side of the radiator 1 arranged. Even with intended Vorschaltgarnitur a manual over the thermostatic valve 6 , So its opening and closing to control the supply of heating medium in the radiator 1 be made.

The 4 and 6 show further embodiments of the radiator according to the invention 1 that with the shut-off and release device 4 here in the form of sealing elements or special sealing elements 50 is formed with a control function, by arranged in the sealing elements bimetallic inserts 51 is realized. This also makes a serial or asymmetrical flow against the two heating elements 10 . 11 possible. In the in the 5a and 5b shown embodiment of the sealing element 50 with bimetal insert 51 is an outer sealing body 52 with an internal passage opening 53 provided in which a piston 54 of the bimetal insert 51 can intervene.
