Description

The invention is based on a switch cabinet arrangement with a switch cabinet housing and a hinge arrangement, the hinge arrangement being designed in such a way that a switch cabinet door attached to the switch cabinet arrangement by the hinge arrangement is connected to the switch cabinet housing in a hanging manner. Such a cabinet arrangement is from DE 10 2016 123 230 B3 known. A similar arrangement is described in DE 10 2019 103 997 B3 .

The switch cabinet arrangements known from the prior art have the disadvantage that the switch cabinet door is sometimes very heavy and cumbersome to handle, which means that manual attachment of the switch cabinet door to the switch cabinet housing can cause difficulties. Known hinge arrangements for such switch cabinet arrangements often include a plurality of hinges arranged vertically one above the other. Accordingly, it is necessary for the attachment of the control cabinet door to the control cabinet housing that the control cabinet door must be attached to the control cabinet housing in such a way that the control cabinet door must be brought into alignment with all hinges of the hinge arrangement at the same time, so that the control cabinet door can be lowered, for example, via hinge bolt mounts onto hinge bolts and so can be connected to the control cabinet housing.

It is therefore the object of the invention to further develop a switch cabinet arrangement of the type described at the outset in such a way that it enables simplified assembly of the switch cabinet door on the switch cabinet housing.

This object is achieved by a switch cabinet arrangement having the features of claim 1. Advantageous embodiments are the subject matter of the dependent claims.

Accordingly, it is provided that a switch cabinet arrangement according to the invention with a switch cabinet housing and a switch cabinet door which is arranged thereon and can be pivoted about a hinge axis and in which a cooling device is accommodated, is characterized in that the switch cabinet door is at least in an open position, in which the switch cabinet door is at least partially pivoted away from the switch cabinet housing is supported at a distance from the hinge axis. Because the switch cabinet door is supported at a distance from the hinge axis, the invention enables a more stable construction, since hanging attachment of the switch cabinet door can be avoided or at least part of the load can be taken from a hinge arrangement by supporting it. In particular, the invention also enables simplified assembly of the control cabinet door, since the support can support stabilization of the control cabinet door in a mounting position, so that an assembly person preferably has at least one hand free to connect the control cabinet door and the control cabinet housing.

Support is preferably understood to mean an element that is attached to the control cabinet door and can at least support stabilization of the control cabinet door in an upright equilibrium position. The element can, for example, be designed to fold out of the control cabinet door or be a component that is separate from the control cabinet door and can be attached to the control cabinet door in an open position, for example for assembly or repair of the control cabinet door. The element is preferably designed in such a way that it also supports the control cabinet door during opening and closing.

A distance from the hinge axis is understood here to mean that a point, in particular a surface on which the control cabinet door is supported, is at a distance from the hinge axis such that the control cabinet door can advantageously be stabilized in an upright equilibrium position. The supporting therefore preferably takes place, for example, in a lower area of the switch cabinet door, particularly preferably on or in the vicinity of a side of the switch cabinet door opposite the hinge axis.

The cooling device preferably includes a heat exchanger, which is preferably designed as an air-liquid heat exchanger, in particular an air-water heat exchanger. Alternatively, the heat exchanger can also be designed as an air-to-air heat exchanger.

The switch cabinet door preferably has a support element on a horizontal underside, which protrudes from the switch cabinet door to a mounting surface of the switch cabinet housing. As a result, the invention enables the support element to be able to support the control cabinet door on the installation surface. The installation area can in particular be a floor area on which the switch cabinet arrangement is installed.

The support element preferably has at least one support roller, so that the support roller can roll on the installation surface when the switch cabinet door moves between the open position and a closed position in which the switch cabinet door closes the switch cabinet housing. Because the support element has at least one support roller, the invention makes it easier to open and close the switch cabinet door. The support roller preferably has a horizontal axis of rotation.

The support element preferably has a damping element which acts in the vertical direction. Due to the fact that the support element has a damping element acting in the vertical direction, the invention makes it possible for vertical forces acting on the support roller not to be transmitted, or only to a limited extent, to the switch cabinet door. These damping properties of the support roller are particularly advantageous when the installation surface is uneven. The damping element preferably has at least one elastomer or consists of it. The damping element is particularly preferably arranged between the horizontal underside of the control cabinet door and the support element.

The support element preferably has a leveling feature with which a distance by which the support element protrudes from the horizontal underside of the control cabinet door can be adjusted. As a result, the invention enables the vertical position of the support element to be adjusted, which is particularly useful when a different vertical positioning of the support element is necessary or desired for an assembly and an installed state.

Preferably, at least one hinge having the hinge axis has a hinge half on the cabinet side, which is designed at least in sections as a folded sheet metal part through which at least one tube carrying a fluid is passed. Because a pipe carrying a fluid is passed through the shaped sheet metal part, the invention enables the control cabinet door and the control cabinet housing to be fluidly connected to one another. The tube is preferably a feed line and/or a return line of the cooling device. The shaped sheet metal part is particularly preferably designed in such a way that the tube is guided through without contact.

The shaped sheet metal part can be designed in such a way that the tube can be manufactured at least in sections from a rigid material, for example a metal. Preferably the tube is made entirely of a rigid material. The shaped sheet metal part can be designed in such a way that when the control cabinet door is opened and closed, no stresses or at least no stresses causing damage act on the tube. For this purpose, the shaped sheet metal part can have a rotary feedthrough with two mutually rotatable, coaxially mounted and fluidically tightly connected sections, via which two ends of the tube can be connected to one another, so that due to such a rotary feedthrough when opening and closing the control cabinet door, the tube is rigid in sections with respect to the Control cabinet door and sections is rigid with respect to the control cabinet housing.

The tube between the hinge axis and a frame of the switch cabinet housing is preferably passed through the cabinet-side hinge half, so that the invention enables the tube to be arranged in the most space-saving manner possible. For this purpose it can be provided that the shaped sheet metal part has a U-shaped section through which the at least one tube is passed, the U-shaped section being open towards the switch cabinet housing. The U-shaped section is preferably designed in such a way that the tube is guided through without contact and/or the U-shaped section has the hinge axis in a region that is furthest away from the switch cabinet housing.

The shaped sheet metal part preferably has a first fastening flange at a first end point and a second fastening flange at a second end point, with which the cabinet-side hinge half is fixed to the switch cabinet housing, preferably to a frame of the switch cabinet housing. The first fastening flange is preferably fixed to a horizontal profile of a door-side, rectangular profile frame of a rack of the switch cabinet housing, with the second fastening flange being fixed to a vertical profile of the door-side, rectangular profile frame of the rack adjoining the horizontal profile.

The switch cabinet arrangement preferably comprises a hinge arrangement, the hinge arrangement having a bearing surface which is designed to be able to support the switch cabinet door at least temporarily.

A support surface is to be understood as a substantially horizontal plane that is suitable for supporting the control cabinet door, so that when the control cabinet door is installed, the weight of the control cabinet door is at least partially borne by the support surface and balancing is also supported, so that the Control cabinet door prevented or a probability of tipping over can be at least reduced. For this purpose, the bearing surface can have, for example, a roughened surface or a groove into which a corresponding ridge on the switch cabinet door can engage, in order to enable the switch cabinet door to be positioned as securely as possible. Furthermore, the supporting surface can have guide rails or also have a clip connection through which the control cabinet door can be connected to the support surface for mounting the control cabinet door.

Temporary wear is understood here to mean that the contact surface is designed to carry the weight of the switch cabinet door at least for a specific time, in particular for the duration of assembly of the switch cabinet door. A permanent carrying of the control cabinet door by the support surface is not expedient, as this would prevent the control cabinet door from being opened and closed with as little resistance as possible. When designing the contact surface, temporary wear can be expressed to the extent that material thicknesses and/or properties are selected in a way that is optimal in terms of weight and/or cost, since permanent loading is not required.

The bearing surface for at least temporarily carrying the control cabinet door enables the invention to at least support the mounting of the control cabinet door on the control cabinet housing, so that the mounting of the control cabinet door can preferably be carried out by just one person. The person can set the switch cabinet door down on the support surface for assembly and then, since the support surface takes on at least part of the weight and the balancing, establish a non-positive connection between the switch cabinet housing and the switch cabinet door.

The support surface is designed in such a way that it can at least temporarily bear more than 25% of the weight of the control cabinet door, preferably more than 50% of the weight, particularly preferably more than 75% of the weight. Temporary is understood here as the duration of the assembly, ie at least 15 minutes, preferably at least 30 minutes, particularly preferably at least 45 minutes. The width of the bearing surface is designed such that it is more than 5% of the width of the control cabinet door, preferably more than 10% of the width of the control cabinet door, particularly preferably more than 25% of the width of the control cabinet door.

The hinge arrangement preferably comprises a cabinet-side and a door-side hinge half, the cabinet-side and the door-side hinge halves of the hinge arrangement being designed to be able to be connected vertically to one another. Because the cabinet-side and door-side hinge halves of the hinge assembly can be connected to each other vertically, the invention enables the switch cabinet door to be slid horizontally onto the support surface, in order to then vertically connect the two hinge halves of the hinge assembly with one another in a non-positive manner. For example, a locking bolt can be inserted without the use of tools for a non-positive connection, but a screw connection is also conceivable.

The hinge arrangement preferably has a first and a second hinge, the first and/or the second hinge being fixed at least in sections to a horizontal profile of a door-side, rectangular profile frame of a rack of the switch cabinet housing. The first hinge is preferably fixed to a horizontal floor profile and has the contact surface that supports the control cabinet door. Because the first hinge has the contact surface that supports the switch cabinet door, the invention makes it possible for the switch cabinet door to be slid horizontally onto the contact surface to require less effort than when the first hinge is positioned higher because the first hinge is close to the ground. Furthermore, the hinge arrangement thus prevents the switch cabinet door from possibly falling down to a greater height if the switch cabinet door slips off the support surface, and the risk of damage and injury would thus increase.

Due to the fact that the first hinge is preferably arranged at least in sections on a horizontal floor surface delimiting a door opening or on a horizontal profile of the switch cabinet housing, the invention enables the first hinge to be attached close to the floor and that it has a greater load-bearing capacity compared to a pure attachment to a vertical profile has, since no exclusively hanging arrangement is provided.

Here, in sections means that the first hinge is at least partially arranged on the horizontal floor surface delimiting the door opening or on the horizontal profile. The first hinge is preferably fixed in a lower corner of the switch cabinet housing and attached essentially in equal parts to the horizontal floor surface delimiting the door opening or the horizontal profile and to a vertical side wall of the housing delimiting the door opening or a vertical profile.

The second hinge is preferably fixed at least in sections on a horizontal roof side delimiting a door opening. As a result, the invention makes it possible for the second hinge to also have a greater load-bearing capacity compared to being simply attached to a vertical profile, since no exclusively hanging arrangement is provided in this way. The second hinge is preferably arranged in the vicinity of one of the upper corners of the switch cabinet housing, it being preferably predominantly attached to the horizontal roof side. The attachment takes place at for example on the upper side of the horizontal roof side, so that the carrying capacity can be further increased. Fastening both on the horizontal roof side and on the vertical side wall of the switch cabinet housing delimiting the door opening or on the vertical profile is also conceivable within the meaning of the invention.

The hinge axis of the switch cabinet door is preferably positioned in such a way that a maximum possible opening angle of the switch cabinet door is at least 90 degrees. Due to the fact that a maximum possible opening angle of the control cabinet door is at least 90 degrees, the invention enables advantageous, in particular complete, accessibility of the door opening, so that, for example, maintenance of the control cabinet arrangement and in particular of components arranged in the control cabinet arrangement is simplified. The maximum opening angle is preferably at least 115 degrees, particularly preferably at least 140 degrees. This can be achieved, for example, by shifting the hinge axis to the outside of the outer circumference of both the switch cabinet housing and the switch cabinet door.

An assembly method for attaching a switch cabinet door to a switch cabinet housing of a switch cabinet arrangement according to the invention comprises the following steps:

• - setting up the control cabinet door, with the control cabinet door being supported at a distance from the hinge axis,
• - Sliding the control cabinet door onto a first half of the hinge on the cabinet side,
• - Connecting a first, door-side hinge half of the control cabinet door and the first, cabinet-side hinge half,
• - Connecting the cabinet door with a second cabinet-side hinge half and
• - Connecting a second, door-side hinge half of the control cabinet door and the second, cabinet-side hinge half.

By supporting the switch cabinet door at a distance from the hinge axis, the assembly method enables the switch cabinet door to be assembled by one person in particular. The first, cabinet-side and the first, door-side hinge halves are preferably fixed near the floor. The connection is preferably carried out with one hand, particularly preferably without tools, so that the person can continue to support the control cabinet door with the second hand. Connecting here means that the control cabinet door, in particular the second, door-side hinge half, is brought into alignment with the second, cabinet-side hinge half in order to enable the second, door-side hinge half and the second, cabinet-side hinge half to be connected. This can include swinging in the control cabinet door, with swinging in preferably only being necessary over a short distance. As a result of the support, the switching cabinet door is preferably already in a position after it has been pushed open, in which the second hinge halves are largely aligned, so that bending forces on the first hinge halves can be minimized or at least reduced.

1 shows a switch cabinet arrangement 100 comprising three switch cabinets 2 according to an embodiment of the invention. The switch cabinets 2 each have a switch cabinet housing 3 which consists essentially of a frame 110 and flat parts fixed thereto, for example a roof element 120 and a switch cabinet door 4 . The switch cabinet door 4 is arranged on the switch cabinet housing 3 via a hinge arrangement 1 about a hinge axis x. The control cabinet door 4 includes a cooling device 41 and is designed to conduct a fluid, here in particular through a tube 32. The cooling device 41 here includes an air-liquid heat exchanger and the tube 32 is the flow of the air-liquid here ity heat exchanger. In alternative exemplary embodiments, the pipe can be the return line of the air-liquid heat exchanger, or the control cabinet door 4 can be designed to include a flow line and a return line.

Generic control cabinets 2 are often about 2 meters high, with the control cabinet door 4 also extending over the entire height of the control cabinet 2 in order to achieve the largest possible opening dimension, so that the control cabinet door 4 can be hung over its entire vertical length must be aligned parallel to the frame 110, in particular to a vertical profile of the frame 110 to which the control cabinet door 4 can be fixed via the hinge assembly 1.

In known embodiments from the prior art, for example, three cabinet-side hinge halves are fixed equidistantly to the frame, while the switch cabinet door has three welded door-side hinge halves equidistantly spaced from one another on its inside at the same distance, which, in order to hang the switch cabinet door in the switch cabinet housing, at the same time with a respective hinge pins must be aligned in order to place them on the hinge pins. This entails considerable installation work, since the control cabinet doors, which are designed as sheet metal parts and have a tubular door frame on the inside and possibly other attachments, can have a considerable weight.

To solve this problem, the invention proposes a switch cabinet arrangement 100, which differs from the switch cabinet arrangements known from the prior art in that the switch cabinet door 4 is at least in an open position, in which the switch cabinet door 4 is at least partially pivoted away from the switch cabinet housing 3 is supported at a distance from the hinge axis x.

For this purpose, the control cabinet door 4 has an in on a horizontal underside 2 shown support element 9, which protrudes from the switch cabinet door 4 to a mounting surface of the switch cabinet housing 3. This allows the support member 9 to support the weight of the cabinet door 4 and keep the cabinet door 4 balanced.

The support element 9 has a support roller 93, the support roller 93 having a horizontal axis of rotation 94 here, so that when the control cabinet door 4 moves between the open position and a closed position, in which the control cabinet door 4 closes the control cabinet housing 3, the support roller 93 on the installation surface can unroll. As a result, the support element 9 supports low-friction opening and closing of the control cabinet door 4 while at the same time relieving the hinge arrangement 1.

Furthermore, the support element 9 has a damping element 92 acting in the vertical direction, the damping element 92 here consisting of an elastomer. The damping element 92 is arranged between the horizontal underside of the control cabinet door 4 and the support element 9 . As a result, the support element 9 supports a quiet and low-vibration opening and closing of the switch cabinet door 4 by reducing vertical force influences, for example as a result of unevenness in the installation surface acting on the switch cabinet door 4, through the damping properties of the elastomer. In alternative exemplary embodiments, the damping element 92 can alternatively or additionally comprise a spring.

The support element 9 also has a leveling element 91 here, with which a distance by which the support element 9 protrudes from the horizontal underside of the control cabinet door 4 can be adjusted. The support element 9 includes an adjusting screw 91 for adjusting the spacing. This allows an advantageous spacing of the support element 9 to be set both for opening and closing the control cabinet door 4 and for installation or maintenance of the control cabinet door 4. The spacing of the support element 9 can thus be adjusted, for example be set so that the support element 9 carries a larger proportion of the weight of the cabinet door 4 for assembly or maintenance, in order to be able to keep the cabinet door 4 in a position of equilibrium better.

The hinge assembly 1 includes here, as in the 3 and 4 shown, a cabinet-side hinge half 11 and a door-side hinge half 12, which are designed to be connected to each other vertically and each have the hinge axis x. Furthermore, the hinge arrangement 1 comprises a first 21 and a second 22 hinge.

3 shows the first hinge 21, in which the cabinet-side hinge half 11 is partially formed as a folded sheet metal part. The tube 32, here the flow of the cooling device 41, is passed between the hinge axis x and the frame 110 of the switch cabinet housing 3 through the cabinet-side hinge half 11, here the folded sheet metal part, essentially without contact. The shaped sheet metal part has a U-shaped section 114 for the passage of the pipe 32 , the U-shaped section 114 being open towards the switch cabinet housing 3 . The hinge axis x has the U-shaped section 114 in an area that is furthest away from the switch cabinet housing 3 .

For attachment to the frame 110, the sheet metal part has a first attachment flange 111 located at a first end point and a second attachment flange 112 at a second end point, with which the cabinet-side hinge half 11 is fixed to the frame 110 of the switch cabinet housing 3. The first fastening flange 111 is fixed to a floor-near horizontal profile 7 of a door-side, rectangular profile frame of the rack 110 of the switch cabinet housing 3 and the second fastening flange 112 is fixed to a vertical profile 113 of the door-side, rectangular profile frame of the rack 110 adjoining the horizontal profile 7. This arrangement on the horizontal and the vertical profile 7, 113 enables a more stable construction, since the control cabinet door 4 is at least not exclusively attached hanging.

The hinge arrangement 1 also has an in 3 bearing surface 5 shown, which is designed to be able to carry the control cabinet door 4 at least temporarily. As a result, the invention makes it possible for the control cabinet door 4 to be supported by the bearing surface 5 during assembly or maintenance, so that assembly can be carried out by one person.

The bearing surface 5 is made up of several surfaces here. On the one hand, it is formed from the upper edges 51 and 52 of the U-shaped section 114 of the cabinet-side hinge half 11 of the first hinge 21, and on the other hand from the surface 54 of the cabinet-side hinge half 21. The advantage of the support surface 5, which is composed of several surfaces, is that the arrangement is such can be designed so that the bearing surface 5 carries the control cabinet door 4 as balanced as possible and can thus simplify assembly. This can be achieved, for example, by sufficiently spacing surface 52 from surface 51 . In particular, the surfaces 51 and 52 can also be designed as guide aids, in that the switch cabinet door 4 has grooves on the underside, into which the surfaces 51 and/or 52 can engage.

4 shows the second 22 hinge, which is arranged here completely on a roof-side horizontal profile 8 of the switch cabinet housing 3 . The cabinet-side hinge half 11 of the second hinge 22 is attached to the top and bottom of the horizontal profile 8 for the most stable construction possible. Since the second hinge 22 avoids a suspension of the switch cabinet door 4 via hinges on a vertical profile of the frame 110 and thus there is no hanging arrangement, the stability of the suspension can be increased. The door-side hinge half 12 of the second hinge 22 can be connected vertically, for example by means of a bolt, to the cabinet-side hinge half 11 of the second hinge 22 and can be connected here to the switch cabinet door 4 by means of three screws 220 .

5 shows the first hinge 21 from another perspective. Here, in particular, the passage of the pipe 32 through the U-shaped section 114 of the first hinge 21 is shown. It can be seen here that the bushing, together with a flexibly designed transition area 33 of the tube 32, enables a rotary movement of the tube 32 as a result of an opening or closing of the control cabinet door 4, with a section 34 of the tube 32 inside the control cabinet door 4 being largely rigid at the same time.

6 shows the in 1 Switch cabinet arrangement 100 shown in a plan view. It can thus be seen that the hinge axis x of the control cabinet door 4 is positioned in such a way that a maximum possible opening angle α of the control cabinet door 4 is at least 90 degrees. So here the control cabinet door 4 of the middle control cabinet 2 can be opened by 140.15° when the control cabinet door 4 of the right control cabinet 2 is open by 90°. If the right-hand control cabinet door 4 is opened further, the middle control cabinet door 4 could be opened even further, since the hinge arrangement 1 fundamentally allows pivoting through 180°.

7 shows an assembly method for attaching a switch cabinet door 4 to a switch cabinet housing 3 of a switch cabinet arrangement 100, comprising the following steps

• - Setting up S10 of the control cabinet door 4, the control cabinet door 4 being supported at a distance from the hinge axis x,
• - Sliding S20 of the control cabinet door 4 onto a first cabinet-side hinge half 11,
• - Connecting a first, door-side hinge half 12, S30 of the control cabinet door 4 and the first, cabinet-side hinge half 11,
• - Connecting S40 the control cabinet door 4 with a second cabinet-side hinge half 11 and
• - Connecting a second, door-side hinge half 12, S50 of the control cabinet door 4 and the second, cabinet-side hinge half 11.

8th shows the second step of deferring S20. After the cabinet door 4 has been set up in a first step S10, so that it is in a substantially upright position, the first, door-side hinge half 12 of the hinge assembly 1 is pushed onto a bearing surface 5 of the cabinet-side hinge half 11 of the hinge assembly 1 . The bearing surface 5 is formed here by the solidly designed hinge half 11 of the hinge arrangement 1 on the cabinet side. In order to support the sliding S20 and in particular the positioning of the control cabinet door 4 for the connection S30, the bearing surface 5 can have a slight indentation towards the center and/or deepen towards the connection point of the 11 hinge halves on the cabinet side and the 12 hinge halves on the door side of the hinge arrangement 1. A support element 9 is provided here to support the control cabinet door 4 when it is set up S10. In alternative exemplary embodiments, the bearing surface 5 can be designed in such a way that it enables the switching cabinet door 4 to be supported at a distance from the hinge axis x, so that no supporting element 9 is required. Conversely, in other exemplary embodiments, a support element 9 can be provided, but no bearing surface 5 .

A locking bolt can be provided for connecting S30, which can in particular be inserted without the use of tools. As in 9 shown, after connecting the first, door-side hinge half 12 of the switch cabinet door 4 and the first, cabinet-side hinge half 11, the switch cabinet door 4 can be connected to the second, cabinet-side hinge half 11 S40. For this purpose, the hinge half 11 of the second hinge 22 on the cabinet side and the hinge half 12 of the second hinge 22 on the door side are aligned so that a connecting element, here a screw 220, can be used to connect S50 the two hinge halves 11, 12 of the second hinge 22 . The door-side hinge half 12 of the second hinge 22 is not visible here in the switch cabinet door 4 .

The support surface 5 can be designed in such a way that the switch cabinet door is already largely aligned for a connection S40 of the switch cabinet door 4 and the second, cabinet-side hinge half 11 . In this way, assembly effort for correct alignment is reduced and the first hinge 21 is subjected to reduced loads, since swinging of the control cabinet door 4 under the second hinge 22 is not necessary or is only necessary over a short range.
