Description
- The present invention pertains to a sub-rack for plugging and unplugging electronic plug-in modules with a housing, which has a front cover plate and a cooling device for the plug-in modules.
- The power consumption of electronic plug-in modules today continues to increase. In connection with the power consumption, waste heat or the thermal output also increases. For a few modules, special cooling devices must be provided, with which the plug-in module is cooled by means of liquid cooling.
- From German patent publication DE 102 10 480 A1, a housing with electronic modules is known, in which a rigidly installed cooling plate carrying a liquid flow is allocated to each module. This arrangement, however, has a difficult construction of the cooling transfer points to the insertable and removable plug-in modules with their electronic components to be contacted.
- German patent publication DE 43 27 444 A1 describes a cooling device for a switchgear cabinet with electrical devices, which are liquid cooled. The liquid cooled components are each connected via a feed line and a return line to a common distributor, which is preferably constructed as a block. Disadvantages include a relatively complicated overall construction and likewise heat transfer that is difficult to implement.
- German
patent publication DE 20 2004 010 204 U1 describes a sub-rack with a housing and with modular electronic components, which are insertable and removable. The sub-rack has at least one liquid distributor in the housing. The liquid distributors are arranged in the housing above or below the push-in area of the plug-in modules. The housing is designed for pure liquid cooling. In this embodiment, liquid cooling must be provided in the housing of the sub-rack in advance. Subsequent installation in an air cooled sub-rack is not possible or is possible only with much difficulty. - For many sub-racks, however, individual plug-in modules are set up after the fact or replaced by updated, more powerful plug-in modules, so that liquid cooling is to be provided later for individual or all plug-in modules.
- Therefore, the problem of the present invention is to create a sub-rack with a housing for receiving electronic plug-in modules, which can be easily equipped with liquid cooling at a later time. This should be possible, in particular for housings with sub-racks installed in an electronics cabinet.
- The present invention provides a sub-rack for plugging and unplugging electronic plug-in modules including a housing with a front cover plate and a cooling device for the plug-in modules. The cooling device comprises a heat sink arranged on the plug-in module and a liquid distributor that is in flow connection with the heat sink via a feed line and a return line. The liquid distributor is arranged on the outside in the front region of the sub-rack.
- According to the invention, simple retrofitting of such a distributor on the sub-rack is allowed by this construction. If individual plug-in modules are replaced and if there is a need for liquid cooling for these replaced modules, a liquid distributor can be easily arranged on the outside of the sub-rack. For an arrangement in the front region, there is also the advantage that the liquid distributor is easily accessible. First, the feed line and the return line to the heat sink can be easily coupled and fixed to the liquid distributor on the plug-in module. In this way, sub-racks installed in switchgear cabinets can be easily expanded. The sub-rack need not be removed from the switchgear cabinet to subsequently install a cooling device for the plug-in modules.
- Preferably, the liquid distributor is arranged for this purpose detachably in the front region. The ability to detach the distributor allows not only simple assembly but also disassembly, if the distributor is no longer necessary, or retrofitting, if, for example, a different liquid distributor is necessary due to changed requirements.
- The sub-rack according to the invention has the advantage that the liquid distributor is freely accessible from the front side of the sub-rack, because it is located in the front region. Maintaining and checking the liquid distributor, especially visual checking, is especially easy to perform also during the operation of the modules.
- Preferably, the sub-rack according to the invention has a receptacle for receiving the liquid distributor in its front region. This receptacle can be constructed, for example, in the form of a flange, into which the liquid distributor is pressed or clipped. The receptacle can also consist of one or more bores, so that the liquid distributor can be screwed in the front region of the sub-rack.
- Especially preferred is providing a receptacle for receiving the liquid distributor on the front cover plate of the sub-rack. In this way, the liquid distributor sits in the front region above or below the plug-in modules. Inserting and removing plug-in modules into and out of the sub-rack is not obstructed by the liquid distributor. This arrangement also has the advantage that the feed and return line to the heat sink, which is arranged on the plug-in module, can be relatively short, because the liquid distributor is arranged in the immediate vicinity of the modules.
- Alternatively, a liquid distributor can also be arranged at the edge regions of the sub-rack, that is, on the side of the push in area of the plug-in modules. A dummy plate can also be provided, which is arranged next to or between two plug-in modules in the front region of the sub-rack and flush with the front plates of the plug-in modules. However, this embodiment is important only when the sub-rack is not completely equipped with plug-in modules.
- Advantageously, a sub-rack according to the invention is constructed so that several liquid distributors can be arranged in the front region of the sub-rack. Thus, several liquid distributor can be retrofitted on one sub-rack. If several plug-in modules are to be cooled by liquid cooling, the sub-rack can also be expanded successively, in which, according to the requirements and number of plug-in modules to be cooled, several or additional liquid distributors are installed. The individual liquid distributors are correspondingly small, so that a space saving construction is possible. The individual liquid distributors can be coupled to each other, so that, in terms of flow, a large liquid distributor with many connections for several heat sinks is produced. Also when additional plug-in modules are retrofitted with liquid cooling, the existing liquid distributors can be kept. Additional liquid distributors are then installed. This can also be realized with a “hot plug method” if the given plug-in modules are exchanged only for plug-in modules with liquid cooling, while the unaffected plug-in modules continue to operate.
- In one preferred embodiment, a sub-rack according to the invention is arranged in a cabinet, especially in an electronics cabinet or switchgear cabinet with a nineteen inch format. The switchgear cabinet has angular profiles in the front region, so that the liquid distributor is fixed to the angular profiles of the cabinet. In this way, the liquid distributor can be arranged and mounted directly on the angular profiles or on a special front cover plate, which is fixed, for example, to the two side angular profiles of the switchgear cabinet. In this way, more space is available for retrofitting liquid distributors, so that large liquid distributors with several feed and return lines can also be used for simultaneously supplying several plug-in modules.
- It is further advantageous to provide combined air and liquid cooling. In addition to the (standard) device for air cooling, a cooling device for liquid cooling is also provided. This allows the cooling of “hot spots,” that is, especially hot zones. Plug-in modules can be cooled separately or selectively according to the individual requirements of cooling. For expanding an air cooled sub-rack by liquid cooling, the liquid cooled plug-in module is also still cooled by air cooling, so that the cooling efficiency is increased.

The drawing figures may not be to scale and certain features may be shown in somewhat schematic or generalized form in the interest or clarity and conciseness.
-
FIGS. 1 , 2, and 3 each show a sub-rack 1 with ahousing 2, into which plug-inmodules 3 are pushed. In thefront region 4 of thesub-rack 1, afront cover plate 5 is provided above a push inarea 6, which area is for inserting and removing the plug-inmodules 3. Underneath the push inarea 6 there is anair inlet plate 7, which has a screen-like construction, so that several small air inlet openings are provided for air-cooling thesub-rack 1. - In
FIG. 1 , the two plug-inmodules 3 each have two through-holes 9 on theirfront plates 8. Coolingfluid feed lines 10 andreturn lines 11 of a cooling device for liquid cooling are guided through the through-holes 9, seeFIG. 4 also. - The
front cover plate 5 arranged above the push inarea 6 for the plug-inmodules 3 has aliquid distributor 12, which is a component of the cooling device. Theliquid distributor 12 is fixed on thefront cover plate 5 of thesub-rack 1. Thefront cover plate 5, however, is connected detachably to thehousing 2 of the sub-rack 1 at opposed angular profiles of the housing, so that thefront cover plate 5 can be exchanged together with theliquid distributor 12. Fixing theliquid distributor 12 on a separatefront cover plate 5, which is fixed detachably to thesub-rack 1, is especially preferred because liquid cooling for a sub-rack can be retrofitted through simple replacement of thefront cover plate 5. -
FIG. 2 likewise shows asub-rack 1 according to the invention, whose push inarea 6 is filled completely with plug-inmodules 3. Five of the plug-inmodules 3 are provided with liquid cooling. - The
liquid distributor 12 arranged above the push inarea 6 preferably has adistributor housing 13 with acover side 14, which is aligned parallel to thefront cover plate 5. At least twoline connections 15 for connecting acoupling 22 are provided on thecover side 14,FIG. 5 . - The
liquid distributor 12 hasseveral line connections 15, which are arranged in two rows one above the other.Line connections 15 a of the top row are provided for connecting respective feed lines 10.Lower line connections 15 b,FIGS. 2 and 6 , are provided for connecting to respective return lines 11. Thus, twoline connections 15 are used for connecting the cooling device of each plug-inmodule 3. - A
main feed line 17 a and amain return line 17 b, which are connected to a not shown heat exchanger, are arranged on oneside wall 16 of thedistributor housing 13 of theliquid distributor 12. Usually, the heat exchanger is arranged in the same switchgear cabinet as the sub-rack. -
FIG. 3 shows a sub-rack 1 with a liquid distributor, which extends over the entire width of thesub-rack 1 and which provides possible connections for each insertable plug-inmodule 3. For example, such aliquid distributor 12 includes possible connections for a total of fourteen plug-inmodules 3 in the use of nineteen inch sub-racks. - The
sub-racks 1 shown explicitly inFIGS. 2 and 3 each have aliquid distributor 12, which extends over the entire width of thesub-rack 1. In an alternate construction of theliquid distributor 12, it may have only connections for a few plug-inmodules 3, especially for three plug-inmodules 3, as shown inFIG. 5 , for example. Theliquid distributor 12 then extends only over the width of three modules. It is constructed as a small block. Such aliquid distributor 12, shown inFIG. 5 , shows the arrangement at the upper left corner of asub-rack 1. Theliquid distributor 12 hasline connections 15 for a total of three modules. In addition to theliquid distributor 12, in thefront cover plate 5 there is areceptacle 18, on which anotherliquid distributor 12 can be attached, if additional plug-inmodules 3 are to be later provided with liquid cooling. In thereceptacle 18, which has a square construction, a cooperating clip, not shown, of aliquid distributor 12 may be disposed. In this way, theliquid distributor 12 is easy to install. -
FIG. 4 shows in detail a plug-inmodule 3 with cooling bodies orheat sinks 19 and two through-holes 9 on afront plate 8 for feeding through thefeed line 10 and thereturn line 11. This plug-inmodule 3 is likewise suitable for holding in asub-rack 1. The spacing between thefeed line 10 and returnline 11 in the embodiment shown inFIG. 4 is greater than for the embodiments of the plug-in modules shown in the other drawing figures, but otherwise the embodiments are all constructed in the same way. Moreover, in the embodiments shown thefeed line 10 may be disposed above or below thereturn line 11 in the various drawing figures. The arrangement of the feed and return lines in this respect may not be important. - As is to be taken from
FIGS. 1 , 5, and 6, aflexible line section coupling 22 is arranged, is provided at the free end of thefeed line 10 and thereturn line 11, respectively. Preferably, thecouplings 22 have an arc shaped or angled construction. The angle here is advantageously between 60° and 125°. Especially preferred is an angle of 90°, like that of thecouplings 22 shown in the drawing figures.Such couplings 22 are especially well suited for connecting to aliquid distributor 12, whoseline connections cover side 14. Bending and resulting damage to theline sections - As shown in
FIG. 6 , in particular, theliquid distributor 12 projects only slightly past thefront region 4 of thesub-rack 1, so that the sub-rack 1 withcoupling 22 attached to the cooling device is deeper than an air cooled sub-rack. Thecouplings 22 extend only slightly past acable collection plate 23, which is arranged above theliquid distributor 12 and which can be provided in sub-racks such as thesub-rack 1. - The sub-rack 1 according to
FIGS. 1 , 2, and 3 includes a combined air and liquid cooling system, because the plug-inmodules 3 arranged in thesub-rack 1 can be cooled first via air cooling, and second via liquid cooling. The cold air for air cooling flows through theair inlet plate 7 in thesub-rack 1. In addition, there is the possibility, by setting up or retrofitting the sub-rack 1 withliquid distributors 12, to install some or all of the plug-inmodules 3 with liquid cooling, in order also to cool individual plug-inmodules 3. - The construction and operation of the sub-rack housing for receiving plug-in modules according to the present invention is believed to be within the purview of one skilled in the art based on the foregoing description. Conventional engineering materials and practices may be used to construct the sub-rack with housing for receiving plug-in modules as shown and described.
- Although preferred embodiments of the invention have been shown and described, those skilled in the art will recognize that various substitutions and modifications may be made without departing from the scope and spirit of the appended claims.
