Description

[0001] The invention relates to a radiator, a radiator system and a method for installing a radiator.

[0002] The long-standing trend towards heat pumps in the field of heat generators increasingly requires the use of radiators in residential and commercial buildings, which are particularly efficient at low flow temperatures and can meet the required heat demand.

[0003] In addition to underfloor heating, fan coil units or so-called heat pump radiators are typically used here. Both products allow for wall mounting similar to a conventional radiator. The fans, especially blowers, built into these devices increase convection within the heat exchanger, thus increasing output at low operating temperatures. During building renovations or refurbishments, older radiators are often replaced with new radiators of the aforementioned type.

[0004] The invention is based on the objective of improving a radiator and a method for installing a radiator.

[0005] The problem is solved according to the invention by a radiator with the features of claim 1, a radiator system with the features of claim 10, and a method with the features of claim 11. Advantageous embodiments of the invention are set forth in the dependent claims.

[0006] In particular, a radiator is created comprising a housing, wherein holding devices with a holding tab each are arranged on a rear wall of the housing, wherein the holding devices are arranged so that the radiator can be hung on brackets mounted on a wall via the holding tabs, wherein the holding devices are further arranged so that a distance of the holding tabs to the rear wall of the housing can be adjusted.

[0007] Furthermore, a method for installing a radiator is provided in particular, wherein the radiator is designed according to one of the embodiments described in this disclosure, comprising: arranging the radiator on brackets attached to the wall by hanging the radiator on the brackets via the retaining tabs, adjusting a desired distance of the radiator to the wall by changing the respective distance of the retaining tabs to the rear wall of the housing.

[0008] The proposed radiator and method allow the radiator to be mounted at any distance from the wall (within a defined range), by hanging it on existing or newly installed wall brackets. This is achieved by adjusting the distance between the mounting brackets, which hold the radiator to the brackets, and the rear panel of the housing. Changing the distance of the mounting brackets to the rear panel also changes the distance between the rear panel and, consequently, the distance between the radiator and the wall. This allows for virtually any desired distance to the rear panel. In particular, it is also possible to select a distance of (almost) zero, so that the rear panel of the housing is flush against the wall.It is also possible during renovations or refurbishments to reuse existing brackets from a replaced older radiator, while at the same time choosing the distance of the newly installed radiator as desired.

[0009] The retaining tabs are arranged, in particular, on an inner side of the housing rear panel. The retaining tabs are arranged, in particular, inside the housing. The distance to the housing rear panel extends, in particular, inside the housing. The retaining tabs are arranged, in particular, parallel to the housing rear panel and / or extend parallel to the housing rear panel. The distance extends, in particular, perpendicularly from the housing rear panel. The brackets extend, in particular, through openings (recesses) provided for this purpose in the housing rear panel. The housing rear panel has corresponding openings for this purpose, at least in the assembled state.

[0010] Radiators are typically suspended from two brackets. Therefore, it is specifically designed that the radiator has two mounting devices. These mounting devices are located, in particular, at each end of the rear housing. The mounting devices (two or more) are specifically located in the upper part of the rear housing.

[0011] It may be provided that additional holes are present in the rear panel of the housing, allowing the radiator to be screwed directly to the wall as an alternative. These holes are advantageously keyhole-shaped.

[0012] The radiator further comprises, in particular, a heat exchanger and a fan, the fan being arranged within the radiator and configured to generate an airflow through the heat exchanger. The housing contains and / or comprises the heat exchanger and the fan.

[0013] The heat exchanger comprises, in particular, a coil or at least one convection plate. The coil includes, for example, one or more pipes through which a heating or cooling medium is circulated. Flat fins are arranged, for example, on these pipes, along which air is guided and heat exchange occurs either towards the air (heating operation) or towards the fins (cooling operation). The at least one convection plate is, for example, arranged on a heating plate. Air is guided along the at least one convection plate, and heat exchange occurs either towards the air (heating operation) or towards the at least one convection plate (cooling operation).

[0014] The blower is specifically designed to generate an airflow. For this purpose, the blower is supplied with an electrical voltage. The blower can, for example, comprise one or more fans. A fan can be, for example, an axial fan, a cross-flow fan, or a radial fan (centrifugal fan). The blower, and in particular its speed, is controlled and / or regulated by a control unit. The blower is typically located below the heat exchanger, specifically at a predetermined distance below the heat exchanger. However, the blower can also be located above the heat exchanger.

[0015] The radiator is, in particular, a fan-assisted convector. The radiator is, in particular, a fan-assisted heat exchanger. The radiator enables, in particular, both heating and cooling operation. The radiator is, in particular, mounted near the floor on a wall. The radiator is, in particular, a heat pump radiator. The radiator may also include a control unit and / or an operating unit. The control unit is, in particular, designed to control the radiator, depending on the operating state (heating or cooling), such that the direction of the airflow corresponds to the respective operating state. For this purpose, the control unit, for example, queries and / or receives information about the operating state and generates corresponding control signals. Furthermore, the radiator may include an interface for remote control and / or for connection to a building management system.

[0016] The radiator comprises a housing. The housing includes, in particular, a front (front panel), a back (rear panel), a top (especially one that is at least partially open), a bottom (at least partially open), a right side, and a left side (side panels). The rear panel covers, in particular, the entire back and / or is, in particular, formed across the entire surface.

[0017] The holding device or parts thereof may be made of or comprise sheet metal. The holding device or parts thereof may be manufactured, for example, by stamping and / or bending and / or other forming processes.

[0018] In In one embodiment, the holding devices each have a support element for each of the retaining tabs, wherein the support element is fixedly connected to the rear wall of the housing, and the respective retaining tab is movably and lockably arranged in the support element. This provides a simple mounting for the retaining tab. The support element can, in particular, form or be designed as a (support) frame in which the retaining tab is arranged.

[0019] In In one embodiment, the support element is provided that at least partially it has the shape of a double angle, the open ends of which are connected to the rear wall of the housing. This allows for a particularly simple design to manufacture. The open ends of the double angle are connected to the rear wall of the housing. For example, perpendicularly angled sections can be provided at the open ends of the double angle, which rest against the rear wall of the housing and are mechanically connected to it (e.g., by welding, riveting, or bolting). The retaining tab is arranged, in particular, parallel to the rear wall of the housing and to one side of the double angle, and perpendicular to the two parallel sides of the double angle. The retaining tab is specifically located between the rear wall of the housing and the side of the double angle.The ends of the retaining tab can be moved along the two parallel sides of the double angle and can be mechanically connected to these sides to fix the distance. For this purpose, at least one elongated hole can be formed in each of the parallel sides of the double angle, through which a screw connection can be made.

[0020] In In one embodiment, the retaining tabs have angled end sections that are arranged parallel to the sides of the respective support element. A screw connection can be formed, for example, with these angled end sections to the sides of the support element, in particular with the parallel sides of the double angle.

[0021] In In one embodiment, the holding device includes guide elements designed to move the retaining tabs in a direction perpendicular to the rear wall of the housing to adjust the distance. This allows for guided movement of the retaining tabs even before they are fully fixed. Specifically, the guide elements prevent the retaining tabs from falling out when they are not yet secured. Furthermore, the guide elements allow the retaining tabs to be pre-installed in the holding device upon delivery, eliminating the need for separate insertion or placement. This simplifies final wall mounting of the radiator, making it easier and more frustration-free (no risk of the retaining tabs falling out).

[0022] In one embodiment, the retaining tabs are designed to have projections that extend above and / or below the respective support element, acting as guides. This allows for the production of particularly simple guides. The projections can be made from the same piece of material as the retaining tab. In particular, the projections can be punched out in the same step from a sheet that also forms the shape of the retaining tabs. It is especially possible for the projections to have a rounded, tongue-like shape, thus avoiding sharp edges and corners.

[0023] In one embodiment, the retaining device includes screws by means of which the distance of the retaining tabs to the rear wall of the housing can be fixed. In particular, it can be provided that the screws extend through holes, especially elongated holes, provided for this purpose in the support element and interact with a thread on the retaining tab or with a thread of a nut arranged behind a designated area of ​​the retaining tab to form the screw connection and to fix the distance by fixing the position of the retaining tab on the support element.

[0024] In one embodiment, a knockout opening is provided in the area of ​​the mounting devices in the rear panel of the housing. This opening allows a recess for the brackets to be created in the rear panel as needed. This ensures that a necessary recess in the rear panel is only created when required. If the radiator is mounted to the wall in another way (e.g., by direct screwing), the knockout openings can remain closed. The knockout opening can be divided into sections that can be broken out individually and separately. This allows for the use of different types and shapes of brackets, to which the shape of the recess can be adapted.

[0025] In one embodiment, the radiator is provided with anti-lift devices designed to prevent the radiator, which is mounted on brackets, from being lifted out. This provides protection against disassembly of the radiator after installation. An anti-lift device engages, in particular, the bracket part on which the retaining tab is mounted, in order to prevent or block upward movement of the retaining tab. Specifically, an anti-lift device is provided for each retaining element.For example, a lifting prevention device can be provided by a plug or clip that is attached to the mounting bracket after the radiator has been hung. This clip then engages the mounting bracket from above and the bracket from below, thus fixing the bracket and mounting bracket together and / or preventing the gap between the bracket and mounting bracket from exceeding a predetermined value. To secure the plug or clip to the mounting bracket, it can, for example, have locking tabs that engage with the bracket.

[0026] Further features for the design of the method result from the description of the radiator designs. The advantages of the method are the same in each case as in the radiator designs.

[0027] Furthermore, a radiator system is also created, comprising a radiator according to one of the described embodiments and brackets for attaching the radiator to a wall.

[0028] The invention is explained in more detail below with reference to preferred embodiments and the figures. These show: Fig. 1 a schematic representation of one embodiment of the radiator (top view); Fig. 2 an enlarged schematic representation of the embodiment of the radiator (top view); Fig. 3 a schematic representation of another embodiment of the holding device (top view); Fig. 4 a schematic representation of another embodiment of the holding device (bottom view); Fig. 5 a schematic representation of another embodiment of the holding device (top view); Fig. 6 a schematic flowchart of an embodiment of the method for installing a radiator.

[0029] The Fig. 1 Figure 1 shows a schematic representation of an embodiment of the radiator 1. The radiator 1 comprises a housing 2. On a rear wall 3 of the housing 2, mounting devices 4, each with a mounting tab 5, are arranged. The mounting devices 4 are designed so that the radiator 1 can be hung on wall-mounted brackets via the mounting tabs 5, the mounting devices 4 being further designed to ensure a distance D ( Fig. 2 The retaining tabs 5 can be adjusted to the rear wall of the housing 3. The heating element 1 also includes, in particular, a heat exchanger and a fan (both not shown).

[0030] The Fig. 2 shows a schematic representation of an enlargement of the in the Fig. 1 The illustrated embodiment of the holding device 4, where for clarity some parts of the radiator 1 have been omitted, is shown. In this embodiment, the holding device 4 has a support element 6 for the retaining tab 5. The support element 6 is fixedly connected to the rear wall of the housing 3, with the retaining tab 5 being movably and lockably arranged in the support element 6. The connection of the support element 6 to the rear wall of the housing 3 can be made, for example, by means of a weld, rivet, or screw connection.

[0031] In the illustrated embodiment, the support element 6 is provided that, at least in sections, it has the shape of a double angle 7, the open ends 8 of which are connected to the rear wall of the housing 3. For this purpose, the open ends 8 of the double angle 7 are bent at right angles (particularly outwards), with the bent areas bearing against the rear wall of the housing 3 and the connection with the rear wall of the housing 3 being formed in these areas.

[0032] It may also be provided for, as in the Fig. 2 In the illustrated embodiment, the retaining tabs 5 (in particular at right angles) have angled end regions 9 which are arranged parallel to the sides 10 of the respective support element 6. In particular, the angled end regions 9 are arranged parallel to the sides 10 of the double angle 7 which run parallel to each other. In particular, the angled end regions 9 abut the sides 10.

[0033] It may be provided for, as in the Fig. 2 In the embodiment shown, the holding devices 4 have guide means 11 which are designed to guide a movement of the holding tabs 5 in a direction perpendicular to the rear wall of the housing 3 for adjusting the distance D.

[0034] In particular, it may be provided, as in the Fig. 2 In the embodiment shown, the retaining tab 5 has projections 12 as a guide means 11, which extend above over the support element 6 and / or below under the support element 6.

[0035] It may also be provided for, as in the Fig. 2 In the illustrated embodiment, the retaining device has four screws 13 by means of which the distance D of the retaining tabs 5 to the rear housing wall 3 can be fixed. In the illustrated embodiment, the support element 6, in particular the double angle 7, has an elongated hole 14 on each of its sides 10, through which the respective screw 13 passes. The retaining tab 5 can then be moved along the elongated hole 14 and fixed by means of the screw 13. The screw 13 engages either in a thread formed on or in the angled end region 9 or in a nut located behind it.

[0036] It may be provided for, as in the Fig. 2 In the illustrated embodiment, a knockout opening 15 is provided in the rear housing wall 3 in the area of ​​the retaining devices 4, through which a recess for the brackets can be created in the rear housing wall 3 if required. In the illustrated embodiment, the knockout opening 15 is divided into individual and separate sections, each of which can be knocked out individually and independently of one another. This allows the recess to be adapted to the shape of the bracket.

[0037] In the Fig. 3 Figure 1 shows a schematic representation of a further embodiment of the radiator and the holding device 4 (perspective view from above). This further embodiment is fundamentally the same as that shown in Figure 2. Fig. 2 The embodiment shown is designed as follows; the same reference numerals denote the same features and terms. In a further embodiment, the support element 6, in particular the double angle 7, is additionally connected to a structural element 16 arranged vertically in the radiator. However, this has no effect on the functioning of the holding device 4, but represents a possible design variant.
