Description

The invention relates to a modular rack, in particular for a device and cable cabinet.

Racks for electrical distribution components, such as stand distributor, racks, server racks or cable cabinets, or distribution cabinets, which are suitable for receiving the many cables and components, such as occur in computer rooms or as the center of a network, are known. They may be coolable if necessary. The market offers so-called 19-inch racks and 19-inch cabinets. Cabinets can have a cabinet body for accessibility and for air conditioning, and a door at the front and possibly at the back. In these cabinets or racks are then attached to carriers hardware such as switches, routers, servers, couplers, patch boxes, racks, power supplies, UPS and the like, as they are needed for networks.

The distributors or racks are available with and without doors, sidewalls, air conditioning. For higher quality or more complicated cabling and distribution cabinets are used, which are also lockable, allow unauthorized access and especially a controlled air flow.

Central component of the distributor, racks or cabinets according to the invention is a single truss-like rack system, in / on the patch panels for fiber optic and copper, servers, cables, connectors, etc. ordered - eg. By screwing, gluing od. Like. Are attached. Depending on the requirements, a housing can be built around this rack rack and this can be converted into a cabinet which, on the one hand, enables air conditioning in the manner of a climate cabinet and, on the other hand, reduces unauthorized access and soiling and dusting of the partially electrostatically attracting components.

The known racks / racks, which can be configured as server racks, switch racks, head stations, etc. - or network cabinets - made it possible to keep order and clarity in the component and cable arrangements, but they themselves were not variable. Thus, when changing or extending the network architecture that used more cables or new components with different masses, a new rack or cabinet was needed. All the components of the distributor / distribution cabinet had to be replaced. Previous racks / racks / cabinets were also delivered in a few large items, which are problems during transport. These are built specifically for each product, unchangeable and therefore not suitable for product change. The modular rack according to the invention allows the installation of all available on the market hardware, even the older generations. It is Z. For example, it is possible to mount several 19 inch girders at different depths. Previous racks allowed only a given depth and when using longer components (the width of the racks is standardized, for example, by the 19 'technology) had completely new, deeper racks are used, resulting in a complete reinstallation of the system.

The known distribution / distribution cabinets also led to significant time losses during the reinstallation. They led to unwanted waste of material, as each time an extension and change in network distribution took place, a completely new distributor-carrier rack arrangement / cable cabinet had to be procured. It is also problematic that heat dissipation / cooling is required in distribution cabinets / racks with components of high electrical power of the components.

So far are - for example, from WO 2010100115 A1 . WO 2012025112 A1 Method for controlling an air conditioning system for a data processing system having a plurality of distribution cabinets known. It is in the cabinets a cold aisle, which is foreclosed against a warm aisle, provided. From an air conditioner, the warm air is sucked in, cooled and blown into the cold aisle and promoted by the electrical components in the warm aisle or the environment, the disclosure of which is referred to as prior art.

The known distribution / cabinets were not sustainable adaptable to new conditions. An expandability was not given. In particular, air-conditioning distributor arrangements could not be retrofitted for a change in the cooling gas flows (eg laterally instead of from the floor or from the ceiling). The cupboard size was fixed and could not be changed, u. a. otherwise the necessary tightness between hot and cold aisle was eliminated. Thus, was wasted valuable resources by constantly new distribution / cabinets.

It is therefore an object of the invention to avoid the disadvantages of the prior art. The object is achieved by a modular rack with the features of claim 1. Advantageous developments emerge from the dependent claims.

A modular rack according to the invention, in particular for a device and cable cabinet, has the advantages, among others:
Expandable in depth
several 19 '' levels are in the depth before and can be retrofitted
Stacking
An air flow control for front and side cooling is via air baffles
pre-and retrofittable
generally retrofittable
convertible
All parts of the rack are compatible with each other

A rack according to the invention comprises: at least one longitudinally expandable front roof truss frame part ( 12 ) in the form of a rectangle open on one side with fastening means; at least one length-expandable front-floor truss frame part ( 12 ) in the form of a rectangle open on one side ( 12 ) with fastening devices; at least two beams extending between the front roof truss frame part and the floor truss frame part ( 16 ) for connecting roof frame part and floor frame part and attachment of computer components, which are fastened to the front of the floor truss frame part and roof truss frame part at these releasably and displaceably mounted.

Advantageously, two substantially U-shaped bent cooling channel dividers ( 19 ), which laterally on the carrier ( 16 ) are fastened and laterally the carrier ( 16 ) each have a one-sided open in the front direction cable and cooling air duct, which are closed in the rear direction substantially air flow tight, provided, with the supply of cold air in the front region of the rack, a passage of the cold air is prevented laterally past the baffles. (in terms of air flow is on 16 - 21 referenced)

This simplest embodiment allows a free-standing rack for computer components.

For applications with longer lengths or even higher weights, such as in server racks, rear roof frames ( 15 ) and rear floor frame parts ( 13 ) with fastened in between rear carriers ( 18 ) for computer components, on the front roof frame and front floor frame parts ( 12 . 14 ) get connected.

When it becomes necessary to expand the depth of the rack due to additional components to be picked up, roof frame part and floor frame part extensions (for extending the depth of the rack to the roof frame part and the floor frame part (FIG. 15 . 13 ) are provided, which are connectable between the roof frame or floor frame parts. These can also be provided in the form of telescopes already in the frame parts and extended in case of need. Due to these extensions, a cabinet can easily be extended with new components without reinstalling, and the existing rack / cabinet parts can continue to be used.

In the rack according to the invention, at least one floor truss frame part and a roof truss frame part can have extensions, such as telescopes or extension pieces for depth extension, whereby a simple depth extension or shortening of the rack or cabinet is possible.

If static problems wg. high weight or long length in the rack can also be a vertical cultivation ( 10 ) between roof frame and floor frame parts ( 12 . 13 . 14 . 15 ) to be built in.

If it is desired to have a closed rack - also referred to as a cable cabinet - can on the existing rack on the carriers and the frame elements ( 12 . 13 . 14 . 15 . 10 ) to form a cabinet end elements selected from side-ceiling floor, rear wall elements or front doors and horizontal cable duct elements ( 20 . 21 . 22 . 23 . 24 . 26 . 50 ) and on the front carrier ( 16 ) and attached Kühlkanaltrennblechen ( 19a . 19b ) Closing plates for the channels and combinations of the same are attached. Typically, these termination components are screwed on, but they can also be clipped, od over spring connections. Like. Be attached.

If cable routing from one rack to another rack is desired, at least one horizontal cable channel element ( 50 ) with cable entry openings ( 51 ) at the level of the cooling duct partitions in the cable duct openings of the front truss frame parts ( 12 . 14 ), whereby to continue from the cooling channel dividing plates, which also act as cable channels, exiting cable ends.

It may be necessary for a rack according to the invention to be connected to at least one further rack in a row, the inner side walls (FIG. 20 ) and the cooling channel dividers ( 19b ) are shortened to form a common front gas space between the adjacent racks. As a result, a common front gas space is formed, which extends from the frame part front of the rack to the component level, ie the area in which the electrical components (patch panels, etc.) are fastened between the carriers. As a result, cooling air can be circulated in the common cold air flow space and passed through the carrier openings with the electrical components. It then flows through the components and emerges warmed up behind the components in the hot air area of the cabinet. From the hot air area, it can then be removed in the usual way - for example, be deducted or routed away.

It is possible, cooling air supply in the common air flow space laterally and / or frontally and / or via a cooling air supply from the floor to allow roof, whereby the spatial and technical conditions can be flexibly accommodated.

One way of thermal management in such racks is that several racks are housed in at least one row arrangement in a common air conditioning housing, which has hot air outflow and cold air flow. There, it is not necessary to provide individual cabinets, but it can be put into open racks, which prevent with cooling channel dividing plates a passage of cold air laterally past the carriers. Also important is the sealing of the outdoor cabinets against the wall of the enclosure. Thus, in such an arrangement, a cold air flow from the rack front to the rear of the rack without provision of individual cabinets or a mixture of cold and warm air done, which can be reintroduced in any way in the common front gas chamber - depending on the circumstances using side coolers, Roof coolers or a cooling floor. It can be saved as individual cabinet doors and thus also Rangierraum be won. The cooling air can be supplied by compressed gas lines or fan arrangements which guide the cooled air into the front gas space.

If third-party components are to be provided in such a series arrangement, which have different dimensions than the racks according to the invention, these can also be fitted by means of fitting plates to measure in the air-conditioning housing

When air conditioning the rack, it is always important to manage cooling air flows efficiently. For this purpose, front baffles between the side walls of the rack and the front carrier frame are mounted so that a passage of cooling air between the uprights and cabinet sides is closed and air flow is essentially only possible through the inside of the stand over from the front to the rear. The cooling channel dividing plates are preferably designed as cable ducts which are open at least on one side and in which (closable) openings for cable passage are formed. It must be distinguished whether they are partitions for extension walls or partitions for end walls. Dividers for end walls preferably extend on one side to the front of the cabinet and thus include the cooling air flow. Partitions for partition walls have shorter end walls, which leave a passage to the adjacent cabinet open, so that a common frontal cold gas channel is formed.

Even with an arrangement of many racks next to each other or opposite a common Frontkaltgasraum is formed, can be introduced into the cold air from various sides and sources and can only pass through the frame openings or the electrical components therein.

The thus formed front air flow space can receive the cooling air necessary for cooling from any desired side - it can laterally via a side radiator, the side of the adjacent cabinet front air flow space; be supplied from the roof via a roof radiator, from a cooling floor from below in a conventional manner. For side-by-side racks / cabinets, cables between the individual cabinet / rack components can be routed through the roof with a roof channel or over the floor via a bottom channel, essentially cooling-air-tight.

Cooling air can be introduced into the front air flow space in a conventional manner laterally via side cooling air supply and / or floor cooling air supply and / or roof cooling air supply and circulated through the support frame in the rear direction of the rack, the cooling air absorbs heat from components mounted in the carriers and heats heated in the rear direction.

Between the stands, the patch panels, servers and other electronic components are attached, which at least partially require cooling. Through this, the cooling air sweeps from the cold front air flow space (cold aisle) to emerge as warm air (warm aisle) behind the patch panels into an aisle. The aisle is formed by the floor and truss elements, if necessary rear wall and side walls. The heated air received in it can be removed from it via the roof or in another known manner. The fact that due to the design no heated air can hit back into the cold aisle, an extremely efficient cooling is achieved.

For large amounts of heat, the discharged hot air can be passed through a heat recovery device.

The fact that now a modular optionally einhausbares rack, which can possibly be upgraded to a closed coolable cable cabinet device is created, arranged in the cable and components clearly arranged and accessible from all sides can be fastened and routed, it is possible at considerably less Space requirement to have an easy to change and adaptable to new conditions cable and component ordering device. Due to the expandability of the arrangement due to their modular design, it is also possible to extend the device in any way or to increase or decrease, whereby their applicability, handling and Environmental friendliness and sustainability is considerably increased due to reusable components and standardized components.

Surprisingly, by the inventive construction when retrofitting a cabinet, an existing cold and hot aisle remain and possibly only the temperature control in terms of larger capacity or the like. Be converted accordingly.

Preferably, at least one support frame has lateral cable guiding and securing means for ordered streamlined lateral flat attachment of patch cables to the side walls. As a result, the cables are kept out of the cooling gas main flow and it can be avoided that turbulence takes place in hot air around cables, which could affect a smooth rapid removal of the heated cooling gases and lead to increased flow resistance. Any device carrier for parts such as cable lugs, socket strips, junction boxes, sensors, limit switches, lighting, etc. can be mounted on the front support frame. Various embodiments of the uprights can be provided - square, rectangular and angled supports can be mounted or retrofitted to the roof truss frame parts and floor truss frame parts throughout the truss.

Since a cabinet arrangement or enclosure of the racks preferably has a hot air exhaust duct, thereby the hot air can be deducted. By active stripping (active conveying elements, such as fans, pumps) can be improved with increased cooling air flow cooling. In the hot air exhaust duct, for example, the residual heat can be measured or recycled. Thus, the heat generated by the computerized components and possibly also by the active cooling elements can be used to save energy in the building - for example, be fed into the heating circuit or used for hot water.

Preferably, both the front roof truss frame parts and the rear roof truss frame parts and the front floor truss frame parts and rear floor truss frame parts are interchangeable with extension or shortening of the rack cable cabinet / or their side sections by telescopes or attachment pieces extendable. Thus, the remaining cabinet elements can be used, a complete complex and error-prone dismantling of the rack / cabinet avoided and a sustainable distributor / cabinet construction can be achieved.

Through the rows of holes in the frame parts a variety of patch panels and shelves can be attached, so that optimum flexibility of the device and cable support device for introducing devices such as voltage stabilizers, couplers, patch panels or the like is possible.

The perforated plates also allow to provide support means for extending from the devices cable until they can be introduced into the cable ducts, thereby ensuring an increased level of security for the cable run. Particularly preferably, the cables are arranged by means of cable clamps arranged on the cabinet wall with release of the central area tightly packed and arranged to allow a free and unhindered as possible air flow and the accessibility or installation of other components.

In 1a is shown a simple skeleton of a rack according to the invention. This basic framework or framework has front girders 16 , which essentially have rack height, on, as well as a front floor frame part 12 . 12a in the form of a rectangle open on one side and a rear floor frame part 13 in the form of a rectangle open on one side and a correspondingly shaped front roof frame part 14 . 14a and a rear roof frame part 15 , On the straps 16 be in the usual way Kabelverteileinrichtungen, patch panels u. Like. - Here in 19 'technique, screwed. The floor and roof frame parts are fastened together with their open sides to form a floor / roof frame. Preferably, the rear and front parts are formed so that their open ends by extension pieces (not shown, indicated by arrows) are extendable. Possibly. can the front frame parts 12a and 14a In their open side frame sections openings for parallel to the front running cable channels 50 exhibit. A suitable cable duct part 50 is in 16 shown. The cable duct part can run parallel to the front, supported by the front frame parts and openings 50 for the entry and exit of cables (not shown). For particularly heavy and long rack arrangements, such as for a server rack, may, as in 1b shown a mounting frame 10 which extends in rack height, are detachably installed between the floor and roof frame parts as well as other rear support 18 for components, as in 1b shown. The frame parts 12 . 13 . 14 . 15 can - as in 2 shown on the mounting frame 10 be attached. By extending the front or rear floor and roof frame parts by means of extension components (not shown) is a depth extension of the cabinet (eg. For installation of other components) possible without replacing the entire cabinet and its installation. This is indicated by the double arrow in the rack floor area of the 1a and also in 3 indicated. In 2 It is shown that between the bottom frame and the roof frame on the side walls of the front floor frame, the front support with respect to the front frame parts 12 . 14 are fixed back, leaving a space between carriers 16 and cable routing front is formed. At the front straps 16 can lateral cooling channel dividers 19a . 19b which cooling air passage only between the carriers 16 and in no case allow laterally to be provided (s. 3 ). By the front of the carrier 16 of the 3 mounted cooling channel dividers 19a . 19b - here with cable grippers - a semi-closed cooling channel in the cooling channel separation plate is limited (better 4 visible), in the cabinet from the front to the front carriers 16 through the dividers attached to the carriers 19 is defined. The partitions 19a seal against side walls and force in a single cabinet a flow of cooling air through the (not shown) components between the carriers 16 whereby a return / mixing removed heated air with mixing with new cold gas prevents and the cooling efficiency is increased.

In 3 the so assembled rack truss structure is shown in perspective, with a possibility extension to the rear ("depth extension") without affecting the assembly is indicated in front of the mounting frame. Such depth expansions are necessary, for example, when installing modified design of other servers.

3a and 3b show the cooling channel dividing plates 19a and 19b , which at the front carriers 16 be attached and an open cable channel 60 form, which seals against cooling air passage on the rack side wall. The cooling air can through the baffles 19 demarcated cable channel does not prevail and is therefore forced by the between the front beams 16 formed opening or fastened therein (not shown) components. In one embodiment, the dividers are 19a for the cable duct at the side of the carrier in the wstl. U-shaped - if a lateral connection of another cabinet and a common wiring is planned, the inside of the U-shaped divider 19b be shortened, which form with another counter-shaped dividing plates of the next cabinet another, closed against cold air passage cable channel.

In 4 is a horizontal section through the rack truss structure of the 3 shown. You can clearly see the back-tight channel in the front cooling channel divider 19a ; which seals off against a side wall (not shown) and forces a cooling gas flow from front to back. At the rear carrier 18 It can be seen that in this embodiment also this is shaped so that it seals against the outflow of heated cooling air.

5 shows the arrangement of 3 and 4 with attached side walls 20 , a laterally opened final strike plate 21 for the cable duct in the cooling channel separator plate 19a as well as one in the wstl. U-shaped cooling channel separator plate 19a on the front carrier 16 which can also serve to accommodate cables, the gas-tight walls of the cooling channels / hot air ducts are specially highlighted. You can clearly see that the vertical support 16 over the one channel 60 forming U-shaped dividers 19a each against the side wall 20 seal and thus an air flow through the carrier 16 force. This is schematically in 6 Shown schematically the cold aisle and warm aisle in a rack assembly 5a when the flow of cooling air into the cold aisle shows.

In 5b is schematically shown a rack for attachment to an adjacent rack. It is clearly recognizable that the cooling channel separating plate 19b for the inner wall is designed so that it is with an adjacent Kühlkanaltrennblech 19b the subsequent rack together forms a common cooling channel.

In 7a is the embodiment of 5a with side walls 20 shown. You can clearly see that the here indicated transparent side walls 20 on the respective Kühlkanaltrennblechen 19a rest and thus the passage of cold air from the rack front between straps 16 and the respective side wall 20 prevent.

A corresponding cooling air flow is in 7b shown. There you can see how cold air flows perpendicularly to the rack front in a rack, pressed in the cold aisle through the components (not shown) and in turbulent flow to the carrier 16 cools and leaves the warm aisle in the direction of the stern.

8th shows the flow in a double cupboard with side cooler. The cold air is injected from the side cooler in the common cold aisle of the side-by-side cabinets and interspersed with the carriers 16 fastened components (not shown) without passing the carriers, since the cooling channel dividers 19 prevent this.

The cooled air is circulated in this lateral flow - the heated air is sucked from the hot aisle, cooled in the side cooler and introduced into the common cold aisle.

9 shows the schematic in 8th arrangement shown in perspective view.

In 10 the cooling is explained by means of a roof cooler. The cooling air is passed from the roof cooler in the channels of the cooling channel dividing plates and leaves them at the bottom of the cold aisle to strike through the components and to flow out of the warm aisle upwards.

11a shows an arrangement of several cabinets in two rows, which are arranged on a central aisle. By means of front coolers cold cooling air is blown in the direction of the rack front, interspersed there to cool the components and is heated from the hot aisles again sucked into the cooler for cooling and use as cooling air. Front doors are unnecessary in this arrangement, if one common housing exists, such as in 11b indicated.

12 shows a similar arrangement of housed rows of racks, wherein the cooling air supply comes from a raised floor below the racks, which flows to the front. In this case, the heated air can not be returned, but is deducted via a trigger upwards.

13a and Fig. b show a rack row arrangement with foreign components of other dimensions. These can be fitted into the architecture by means of matching elements / fitting plates so that the advantageous cooling air flow from the rack front to the rear remains ensured without the mixing of cooling air and warm air.

14 and 15 show a detail of the vertical floor and / or roof cable duct 60 , The cable channels 60 the cooling channel dividing plates 19 Guided cables can be routed through the rack roof or rack floor to adjacent racks. To do this, the cables enter from the cooling channel separator plate channels 60 a vertical tray-like cable channel member attached to the ends thereof 50 (S. 15a ) with cable entry openings 51 on which they can be led to the next closet.

The tray-like vertical cable channel element 50 is in 15a shown in perspective. You can clearly see the cable entry openings 50 in which, if necessary, the cable duct 60 the Kühlkanaltrennbleche ends. In this embodiment, the hot air is withdrawn from the hot air duct upwards.

Thus, the invention is a novel modular equipment rack system that serves to protect, support, and arrange network components and cables, but is much easier to handle than previously used rack systems, is easily expandable, and easy to cool, and significantly lighter construction and also transportability.

In the following 16 to 21 is schematically illustrated the variability of the air duct in various rack assemblies according to the invention. 16 shows schematically the air flow on a single-bar with front ventilation, 17 shows the embodiment of the 16 in another embodiment with front and side ventilation, wherein the cooling air is also guided laterally by components.

18 explains the cooling air flow in side and roof cooling on a single rack, and 19 the cooling air guidance with side and front cooling at the single rack of the 18 , 20 explains the cooling air flow in a double cabinet with side cooler; and 21 the cooling air duct at the double rack of 20 with side and front coolers. From the 16 to 21 Thus, the great variability of the racks according to the invention can be estimated, although these illustrated embodiments can not cover all possible combinations of air ducts through several cabinets.
