Description

Wall or door part or insert for wall or door part of a control cabinet system

The invention relates to a wall or door part or insert for a wall or door part of a control cabinet according to the preamble of claim 1 and a control cabinet system according to claim 10 and a method for installing and removing a cooling or air conditioning module in such a control cabinet system.

The devices installed in control cabinets or control cabinet systems generate heat during their work. This must be dissipated, otherwise the temperature inside the control cabinet will rise and reach inadmissible values that can damage or destroy the devices.

A large number of cooling systems for control cabinets have become known which are designed in such a way that the heat is removed from the interior of the control cabinet. DE-OS 35 04 207 shows a control cabinet with a cooling device, which is designed as a heat exchanger and is placed on the outside of a control cabinet wall.

DE-PS 34 36 407 shows a cooling device that can be inserted into the interior of the cabinet. This has the disadvantage that less space is available in the interior of the control cabinet for internals.

From US-PS 5 467 250 a control cabinet is known in which a heat exchanger is housed in the control cabinet door.

DE-A-196 01 456 shows an air-conditioned switchgear cabinet with a cooling or air conditioning device or integrated in the door or in a wall unit Heat exchanger, the wall element or the cabinet door being designed as a housing for receiving the components of the cooling or air-conditioning device and / or the heat exchanger.

The caloric requirements for control cabinets of the type mentioned are different. There are control cabinets that are equipped with strong heat-generating electrical or electronic devices. These require strong cooling with a fully-fledged air conditioning system that works according to the reverse Camot process. This applies in particular when a control cabinet with such content is installed in a hot environment, for example in the machine hall of a paper mill. There are, in turn, control cabinets with internals that hardly generate any heat, so that the cooling requirements are low. Furthermore, there are of course seasonal influences that also determine the cooling requirement. In many cases, the cooling requirement cannot be precisely determined in advance. It often happens that a

Control cabinet was initially intended for a specific application, but is then used for another. In such a case, a change in the type and scope of the cooling device is necessary.

The location of a machine is usually not known when planning series machines. According to the prior art, the cooling system must then be adapted or retrofitted depending on the climate situation. Depending on the climatic situation, the temperature or humidity at the installation site can vary greatly.

In all of the control cabinet systems known from the prior art, it was necessary to remove them completely from the control cabinet when changing the cooling or air conditioning device; completely shut down the control cabinet system and restart the system after installing the new cooling or air conditioning system. In addition to the complex installation and renovation work, this had the Another disadvantage of long downtimes. Another problem with the conventional systems known from the prior art was that in the event of failure of the cooling or air-conditioning system, emergency operation was not possible and the entire system had to be shut down during the repair.

Another problem with known systems is that a linked system does not allow a single cabinet to be switched off, since this may stop the entire production of a production line. So far, in such a case of cooling failure, the entire system was shut down or control cabinet doors were opened to avoid overheating of the electronic components. When operating with the doors open, the electronic components installed in the cabinet become very dirty. Furthermore, there is a great risk of accidents for the operating personnel, since current-carrying components are accessible without touch protection. Statistically, cooling problems occur after two to five years.

The invention is therefore based on the object of a wall, base, door or roof part, an insert for a wall, base door or roof part of a

Specify control cabinet system with which the disadvantages of the prior art described above are overcome. In particular, a control cabinet system with such a wall, base, door or roof part or insert should also be specified, which is inexpensive to manufacture, flexible in use and space-saving in storage.

This object is achieved by a wall, base, door or roof part or an insert for a wall, base, door or roof part according to claim 1, a control cabinet system according to claim 11 and a method according to

Claim 16 solved. With the invention, the inventor has created a modular system which makes it possible to always use one and the same model of the cabinet body, or one and the same model of a door or a wall element, and to implement different cooling devices simply by exchanging the cooling or air-conditioning module . At the same time, the overall system is flexible.

In the following, for better illustration of the principle according to the invention, this is to be illustrated using a control cabinet door, without being limited to this.

Depending on requirements, cooling or air conditioning modules of different capacities and different technologies are installed in the door or wall parts or inserts for door or wall parts. Corpus and empty door or wall parts can be kept in large quantities. If necessary, i.e. When ordering from a customer, the individual

Control cabinets are made ready by equipping the cabinet body with a door or wall elements or inserts for this with the appropriate cooling or air-conditioning module. A cooling or air conditioning module is generally installed simply by hanging the cooling or air conditioning module in place. The corresponding cooling or air-conditioning modules can be used or exchanged without specialist knowledge and without special tools.

Another advantage is that the external fan is always integrated in the corresponding cooling concept, and cost savings are achieved for the individual cooling systems that will be used later.

It is very important for the invention that complete cooling devices for different purposes, such as have previously been used in control cabinets for air conditioning, are dispensed with and the cooling system is essentially split into two subsystems. The The first subsystem comprises at least one fan device, for example for sucking in control cabinet air, and at least one opening arranged in a wall, base, door or roof part or in use for the wall, base, door or roof part, for example for sucking in ambient air. The fan device and the opening of the subsystem is, according to the invention, arranged in the wall, base, door or roof part or in the insert for the wall, base, door or roof part in such a way that, when the cooling or air conditioning module is not installed, at least one emergency operation function means an emergency cooling or air conditioning of the control cabinet can be taken over.

The second subsystem represents the cooling or air conditioning module. According to the invention, the first subsystem is designed such that together with the second subsystem; i.e. the cooling or air conditioning module, at least one of the cooling devices mentioned below is formed:

- an air-air cooling device;

- an air-water cooling device;

- an air-refrigerant cooling device;

- an air-refrigerant air conditioner with heating

- a heat pipe cooling device;

- A cooling element cooling device;

- or a combination of several of the above-mentioned cooling or air conditioning devices. In contrast to the system according to the invention, the cooling unit or air conditioning unit according to the state of the art always consists of a single machine unit, which can generally be installed ready to plug in. This concept of the machine unit was abandoned in the modular cooling system according to the invention. As described, the modular cooling system essentially consists of two units or subsystems. A fan device is always part of the first subsystem. This fan device can be operated together with the cooling or air conditioning modules, but also alone as a simple filter fan.

For remote control e.g. Remote maintenance can the Kühlbzw. Air conditioning devices can be equipped with means for remote control or remote maintenance, for example via telephone.

In the case of the assembly of the two subsystems, the first

Subsystem comprising a fan device and an opening with the second subsystem in the form of a cooling or air-conditioning module comprising a further fan and a further opening an air-air cooling device, the fan device and the opening of the first subsystem take over the supply of the external circuit.

When assembled with another cooling or air-conditioning module comprising a fan, an opening and a condenser for an air-refrigerant cooling device, the ventilation device and the opening of the first subsystem are supplied with the air circuit of the condenser.

From these two examples it is immediately clear to the person skilled in the art that the fan device and the opening of the first subsystem are part of each cooling device, which can be achieved by assembly with a cooling or Climate module results, and depending on the type of cooling device to be implemented, the components of the first subsystem take on different tasks.

If, for example, the aggregates of the first subsystem are not required for the formation of the cooling device in an air-water cooling device, they are put out of operation and only provide the emergency running properties of the system.

This is to be understood to mean that in the case, for example, of the air-water cooling device accommodated in the cooling or air-conditioning module fails, the system does not have to be completely switched off, but rather the cooling or air-conditioning module can be removed and the control cabinet in emergency operation mode with the still existing first subsystem comprising the fan device and the air intake opening can continue to be operated.

In this way, the modular design not only achieves an advantage with regard to the simple interchangeability and upgradeability or retrofittability of control cabinets for a wide range of applications, but also minimizes or completely avoids downtimes of the entire control cabinet system in the event of cooling device failure.

In an advantageous embodiment of the invention it is provided that filter devices are provided on both the fan device and the opening of the first subsystem in order to retain dust and dirt particles from the ambient air drawn in.

The ease of use and interchangeability of the cooling or air conditioning modules, even by inexperienced personnel, can be achieved in that the in the door or wall part or the use for a door or wall part

Receiving device for the second subsystem in the form of the cooling or Climatic module in the respective insert or wall part includes mounting devices for the cooling or air conditioning module, which can be unlocked and locked using the keys of the cabinet door locking devices. In such a case, only a single key is required for the entire system, for example the key which is used to open the

Control cabinet door is required.

It is particularly preferred if the first subsystem comprising the fan device and the opening comprises a sealing device in order to be able to produce an airtight connection between the fan device and the opening on the one hand and the exchangeable second subsystem in the form of the cooling or air conditioning module. It is advantageously provided that the first subsystem has a flap with a sealing element in the area of the fan device.

The electrical supply to the individual components can be implemented using a cable with a plug. The built-in cooling or air conditioning module, for example an air conditioning unit, water cooler or air / air heat exchanger, can always be supplied with voltage from the permanently installed fan module in the control cabinet. This has the advantage that when

No electrical engineering knowledge is required to install and remove a module, since the module is plugged in via a coded connector and is automatically switched to the corresponding operating mode by a corresponding coding in the connector system.

The fan device, which is fixedly mounted in the door or in the side part, etc., particularly preferably has a direct cable connection for energy supply. Since the fan device of the first subsystem is not replaced in terms of modularity, it can be permanently connected to the power supply of the control cabinet via electrical cables.

The fan device of the first subsystem also has a Connection cable, which is equipped with a coded plug at the end. In the case of a built-in cooling or air conditioning module, the corresponding module is supplied with electrical energy via this multi-core cable, but at the same time the fan device of the first subsystem is controlled according to the module used. This control always depends on the type of cooling or air conditioning module used. If, for example, an air / air cooling module is used, the fan of the fan device is switched to continuous operation.

If an air / air conditioner, i.e. a cooling device according to the left-handed Carnot

Process, used as a module, the fan of the fan device is only operated together with the compressor, since cooling of the condenser circuit is necessary only as long as the compressor is running.

If an air / water cooling device is used, this supplies cable

Plug connection, the module used with power, the fan or fans of the fan device is or are not used and therefore not controlled.

The different operating modes shown above are implemented using a corresponding wiring diagram. The connector system is compatible. The corresponding control is located in the cooling module used. Simply plugging in the appropriate system automatically switches to the correct operating mode.

If the first subsystem is operated alone, without a cooling or air-conditioning module being used, the plug is inserted into a plug socket located on the fan device. The fan can now be operated continuously or via a simple thermostat. It is particularly preferred to make the receptacle or sockets for the plugs on the cooling or air conditioning module and on the fan device compatible, that is to say that the plug for the ventilating device is inserted both in the receptacle device of the plug on the cooling or air conditioning module and on the fan device can be and vice versa. This way and

As described above, the plug inserted there can be removed from the fan device, for example, by a simple handle without electrical engineering knowledge, for example in the event of a failure of the cooling or air-conditioning module, and emergency operation can be implemented without having to reconnect electrical lines.

In addition to the door or wall part or insert for such a door-wall part of a control cabinet described in detail above, the invention also provides a control cabinet system comprising such a door or wall part or an insert for such a door or wall part.

A particularly advantageous embodiment of a control cabinet system comprises a control cabinet body with a cutout on a side wall or the door part, in which the insert according to the invention comprises the first

Subsystem with a Ventileinrichtuπg and the opening and optionally a second subsystem comprising a cooling or air conditioning module is attached. The attachment of the insert according to the invention in the cutout can be produced, for example, with the aid of screw connections or else in a simple manner by means of clip connections.

In particular in the case of a control cabinet system comprising an embodiment of the invention in which the fan device includes a flap with a sealing element, the installation and removal of a cooling or air conditioning module can be carried out in the following simple manner: First, the flap of the fan device with the sealing element is pivoted from a first position, in which the sealing element rests on the cooling or air-conditioning module and ensures an airtight connection between cooling or air-conditioning module and fan device, into a second position, in which this airtight connection is released . The cooling or air-conditioning module is then either inserted into the receiving device for the cooling or air-conditioning module or removed from it, for example when a door insert is pulled out upwards or pushed in from above.

Subsequently, the flap of the fan device is pivoted again from the second to the first position, an airtight connection being established between the first subsystem and the cooling or air-conditioning module if a cooling or air-conditioning module is installed. The flap particularly preferably comprises a holding device for the built-in cooling module.

The flexibility gained for the first time in control cabinet construction with the invention is illustrated once again by the following example:

When developing a machine, e.g. a machine tool, the

Enclosure air conditioning issue generally not given enough attention. This is due to, among other things. the fact that an exact determination of the necessary cooling capacity and the arrangement of the individual units in the air-conditioned control cabinet is not possible in advance. When designing and designing a machine, e.g. one

Series machine, the geographical location where a control cabinet is installed is often not yet known. It is therefore often not possible to determine in advance which cooling system is necessary or suitable. According to the invention, this problem can be solved in an ideal manner in that a basic system with a fan device and opening by installation of the suitable cooling or air conditioning module can be adapted to a wide variety of operating conditions without conversion work.

The invention is explained with reference to the drawings. Show it

FIG. 1 shows a first embodiment of the invention, in which the base unit or the first subsystem comprising the fan device and the opening are integrated in a system door. The system door includes 9/65284

13

Recording devices for receiving various cooling or air conditioning modules, so that the base unit or first subsystem and cooling or air conditioning module or second subsystem can be combined to form different cooling devices.

FIG. 1a shows a closed control cabinet with control cabinet body 1.1 and 1.2 and the system door mentioned above. Figure 1b shows the control cabinet 1 with the door open. In FIGS. 1a and 1, the opening 120 defined in the lower region of the door can be clearly seen, which in the present case is designed as an air inlet filter and can have, for example, a filter mat which can be replaced from the outside and which, depending on the application, is a coarse, a standard or a fine filter . In the upper area of the door, the fan device 126 of the first subsystem 100 is arranged, which in the present embodiment can include a high-performance radial fan controlled by temperature and speed.

In an advantageous embodiment of the invention it can be provided to arrange a vacuum box in the door. With the help of the vacuum box, the pressure inside the cabinet and thus also the degree of contamination of the filter mat can be monitored. By installing a vacuum box in the first subsystem, it is possible for all conceivable applications, i.e. regardless of the configuration of the second subsystem, for example as an air-air or air-water cooling device, to monitor an upstream filter mat for contamination.

The previously mentioned Rad ail-Venti lato r is connected to a power supply via plug connections. The speed control of the radial fan allows noise optimization.

In addition, an air outlet duct is formed in the upper door area, through which the air sucked in by the radial fan is released into the environment can be. The air outlet duct 124 can also be provided with a grille and a filter mat and is thus protected from coarse soiling.

The basic system or first subsystem is already sufficient for one

Cooling of the control cabinet in many applications, in particular, it ensures cooling in an emergency. 1c shows the embodiment according to FIGS. 1a and b in a side view. The radial fan 126 is clearly recognizable. On the one hand, it sucks in cool ambient air into the interior of the body without a built-in cooling or air-conditioning module and, on the other hand, discharges warm air from the interior to the outside, thus ensuring simple cooling of the control cabinet or, if necessary, emergency cooling.

The embodiment shown in Figure 2 is in

The basic principle of one of FIG. 1, that is to say the control cabinet body and the control cabinet door are identical to that of the control cabinet according to FIG. 1. However, the difference lies in the cooling device. As in FIG. 2a, which clearly shows a control cabinet with the door open, the control cabinet now has a second subsystem in the form of a cooling or

Climate module 110 on. In the present case, the fan device 126 and the opening 120 of the first subsystem 100 complement one another with the cooling or air conditioning module 110 of the second subsystem to form a so-called air-air cooling device. How this addition comes about can be illustrated particularly well in the view according to FIG. 2b. After installation of the cooling or air-conditioning module, the fan device 126 and the opening 120 of the first subsystem 100 now take over the task of the external cooling 150. That means that ambient air is sucked in through the opening 120, transported through the channel of the cooling or air-conditioning module and by means of the fan the environment in turn. During the air of the outside air circuit from the opening 120 arranged in the lower door part to the fan device of the first subsystem and the grilles 124 arranged above the fan device flow to the outside, the latter heats up and thus cools the warm air drawn in from the interior of the cabinet by the radial fan 154 arranged in the cooling or air conditioning module 110 in a separate second circuit 152, the warm air in the lower part of the cooling or air conditioning module in turn to that

Inside the cabinet is given.

In the embodiment according to FIG. 3, the cooling or air-conditioning module comprises an air-water heat exchanger 160. The fan device and the opening of the first cooling device are inserted by inserting the cooling or

Climate modules according to FIG. 3 are put out of operation, since cooling by means of ambient air sucked in is not necessary here, but is instead taken over with the aid of water fed into the cooling or climate module 110.

However, if the cooling or air conditioning module 110 fails, the cabinet can continue to be operated, and there are no downtimes. In such a case, the cooling or air conditioning module 110 is removed and the fan device and the opening of the first subsystem come into action and ensure emergency cooling of the interior of the control cabinet when the air / water cooling or air conditioning module is removed.

A further variant of the invention is shown in FIG.

The cooling or air conditioning module 110 essentially accommodates a condenser 170, so that a compressor or condenser cooling device is formed together with the first subsystem 100, including the fan device 126 and the door opening. Here again, the fan device 126 and the opening of the first subsystem take over the function of the so-called external cooling circuit, while the evaporator represents the function of the internal circuit.

In such a case equipped with an evaporator or condenser

Cooling modules can also be provided for heating devices. Such a system is referred to as an air conditioner because it can maintain a predetermined temperature regardless of the environmental influences by means of appropriate control. Of course, the other cooling devices described above (air-air; air-water etc.) can also be supplemented with heating devices for air conditioning units.

FIGS. 5A to 5E show a second embodiment of the invention. In contrast to the embodiments shown in FIGS. 1 to 4, in which the system according to the invention was part of a door or wall part, in the embodiment shown in FIGS. 5A to 5E the system is an insert which is inserted into a door or wall cutout Control cabinet can be installed. Such an embodiment has the advantage that the modules according to the invention can be installed in a simple manner in already existing systems without having to replace doors or wall parts on the control cabinet itself. The system according to the invention can namely be very easily inserted into a cutout made in the door or in a convertible element.

FIG. 5A shows a detailed view of the first subsystem 100, in which the fan (s) 126 can be clearly seen, as well as the flap 102 with hinge 104.

FIG. 5B shows the invention in a representation of the entire page

System. The fan device 126 of the first is in the upper part of the insert Subsystem 100 arranged. The flap 102 mounted above the fan device, which can be pivoted away from the air device with hinges 104, can be clearly seen. On the flap itself there is a protruding plate 106 and a sealing device 109, which functions as a stop lip. Furthermore, a seal 109 is arranged on the cooling module itself towards the flap 102 and towards the outer plate 111. The sealing device 109 on the module and the flap provide an airtight connection between the cooling or air conditioning module 110 and the first subsystem, including the fan device 126 and the opening 120, after the cooling module has been installed.

If a cooling or air-conditioning module is installed in the insert according to the invention, this can be done in a very simple manner. Installation is shown in detail in Figures 6A-6E. Essentially, the flap is pivoted away from the first fan device, the cooling or air conditioning module is inserted into the intended receiving device in use, and the flap is pivoted back into the closed position shown in FIG. 5B, an airtight corridor for the connection between the cooling or air conditioning module and first cooling device is produced by the sealing device 109, which preferably comprises rubber seals.

In the view according to FIG. 5C, the opening 120 arranged in the lower part of the insert and belonging to the first subsystem can be clearly seen, as well as the closures 140 arranged on the side of the flap, which are designed as pioneers and the flap 106 in the or

Hold air conditioning module 110 in the pressed position. Furthermore, the vacuum can 200 can be recognized for the detection of filter contamination.

FIG. 5D shows the closure 140 of the flap of the fan device of the first subsystem in detail. The closure is advantageously with the same

Locking system like the closet door, for example the same Square screw head 142. In this way, with the same key with which the cabinet door is opened, the cooling or air-conditioning module can be secured or unlocked in the receiving device provided in the insert.

FIG. 5E shows the overall system according to FIGS. 5A to 5E from above. The sealing element 109 arranged on the cooling or air conditioning module 110, for example, for establishing the airtight connection between the cooling or air conditioning module and the first subsystem 100 can be clearly seen.

The expansion of a cooling module 110 is shown in detail in FIGS. 6A to 6E.

If the closures 140 are opened, the cooling or air-conditioning module 110 pivots due to its own weight around the pivot point 160 and the flap 102 around the hinge 104 as shown in FIGS. 6B and 6C, as a result of which the tight connection between the cooling or air-conditioning module and the first one Subsystem canceled. In the position shown in FIG. 6D, the cooling or air conditioning module 110 can be removed in the direction 162. The basic or first subsystem shown in FIG. 6E then remains. The

A cooling or air-conditioning module is installed in the sequence from FIG. 6E to FIG. 6A, in the position shown in FIG. 6B generating a negative pressure through the opening 120 and the cooling module being drawn onto the front plate. In the position shown in FIG. 6A, the flap 102 is closed with the closures 10. By tightening the closures 140, the nose or stop lip 106 is pressed against the cooling module and thus the airtight connection between the first subsystem 100 and the cooling or air-conditioning device is established with the aid of the sealing elements 109.

FIGS. 7A to 7C again show the concept according to the invention compared to the prior art. In the state of the art 7A, the cooling or air conditioning device is a unit 500 which is assembled as a whole in the control cabinet.

The inventors have now recognized that very important advantages such as exchangeability, emergency operation can be achieved if, instead of an air conditioning device, a separate system consisting of two subsystems is used, comprising a first subsystem 100 and cooling or. Climate modules 110. FIG. 7B again shows the basic components of the first subsystem 100 and FIG. 7C shows the system with the first subsystem 100 and cooling or air conditioning module 110 resulting in the overall system.

It is particularly advantageous if the installation of different cooling modules is recognized, for example, via a coded plug device for the power supply. For example, if the air-water cooling module is installed, the air device of the first subsystem that is not required is automatically deactivated; When installing a compressor / or condenser cooling or air conditioning module, the fan device is controlled, for example, according to the outside temperature, i.e. switched on and off and operated continuously with an air-air cooling module.

Depending on the installation of the different cooling or air conditioning modules, the cooling operation proceeds as follows:

a) System without cooling or air conditioning module: a control cabinet only shows the first subsystem without cooling or

Air conditioning module, the fan can be operated together with the filter insert as a filter fan by connecting the mains supply. The fan is generally a radial fan.

The fan in the upper area of the cabinet sucks the warm one

Air and passes it on to the environment. Fresh air is in the lower Area supplied through the opening, which is a filter insert in the present case.

b) System with built-in cooling or air conditioning module (compressor cooling device)

By simply inserting a cooling or air conditioning module, comprising a compressor, an active cooling device is formed together with the first subsystem, including the fan and the opening.

The already mentioned radial fan in the upper area of the door serves as an external fan, which sucks the air through the filter insert over the condenser and releases it to the environment. This air circuit is separate from the cabinet interior.

The cooling or air conditioning module itself has an integrated radial fan, which circulates the cabinet air and removes heat via the evaporator. The integrated hot gas condensate evaporation eliminates the need to collect and collect condensate. The condensate evaporation does not require any additional energy expenditure.

c) System with alternative cooling or air conditioning modules

It is also possible to install a module that forms an air-air cooling device together with the first subsystem. The air flow is identical to that described in section b). If an air-water cooler is designed, the module is simply connected to an external water supply. With this type of cooling, the integrated radial fan has no use except for emergency operation.

The system of modular cooling or air conditioning units according to the invention has the advantage that when the cooling or air conditioning module is replaced, emergency cooling is provided by the activated filter fan at all times. This is especially true in the event of failure.

Furthermore, the door can always remain mounted on the cabinet during maintenance, replacement and repair work, which prevents costly machine downtimes.

The maintenance or replacement of the filter mat can be done without

Power supply is interrupted.

The cooling or air conditioning modules can be removed for the purpose of service and maintenance. The control cabinet temperature can be removed after removing the cooling or air conditioning module with the fan and opening the first one

Subsystem can be achieved. Such a "downgrading" of the cooling quality is temporarily permitted.
