Definitions

  • the invention relates to a cooling arrangement for an electrical or appliance cabinet, as claimed in the preamble of patent claim 1 .
  • electrical cabinet or appliance cabinet is intended to mean, in an entirely general form, all types of cabinets, housings, cabins or boxes which have an internal area or functional area which is sealed at least with respect to a fluid exchange, for holding electrical or electronic appliances and/or installations. Electrical or electronic appliances or other installations such as these produce heat during operation. In order to dissipate this heat from the interior of the functional area, cooling arrangements such as those mentioned initially are used in order to avoid overheating of the appliances and/or installations.
  • the amount of heat to be dissipated is highly dependent on the appliances and/or installations arranged in the functional area, and their method of operation. In addition, this energy is dependent on the environmental conditions, for example an ambient temperature, solar radiation at the installation location of the electrical or appliance cabinet, etc.
  • known electrical or appliance cabinets are generally designed with double walls. An inner housing with inner walls and a cover as well as a base surrounds the functional area.
  • the required cooling fluid flow rate can be reduced by use of an air-to-air heat-exchanger in which the overall surface area of the separating boundary surface between a first fluid flow and a second fluid flow, to which heat is intended to be transferred from the first fluid flow, is enlarged or has been enlarged, thus reducing the noise emission created by fans for the same or a better heat dissipation performance.
  • U1 proposes, for this purpose, an apparatus with an air-to-air heat-exchanger in order to provide cooling air for an electrical cabinet, in which the cooling air flows in a fast air flow through a heat-exchanger cassette, and environmental air flows in a second air flow through the heat-exchanger cassette, and the two air flows are produced by fans.
  • the apparatus has a mounting unit which can be fitted with a variable number of physically identical heat-exchanger cassettes and a variable number of physically identical fans.
  • the plurality of physically identical heat-exchanger cassettes in the mounting unit are arranged parallel alongside one another.
  • a newly installed electrical or appliance cabinet is initially provided, for example, only in one area with appliances or installations which produce heat during operation.
  • Another area is completely empty, or, for example, is fitted with passive distribution installations, which do not produce any heat, or only a small amount of heat, during operation.
  • passive distribution installations which do not produce any heat, or only a small amount of heat, during operation.
  • the invention is therefore based on the object of providing a cooling arrangement for an electrical or appliance cabinet which allows better flexible matching of the cooling conditions to the respective requirements, and preferably has a small physical height.
  • a cooling arrangement for an electrical or appliance cabinet which has a functional area with a cross-sectional area which extends along a longitudinal axis, wherein appliances and/or devices which produce heat during the operation can be arranged or are arranged in the functional area
  • the cooling arrangement comprises a mounting arrangement whose longitudinal axis to which the cross-sectional area corresponds and which has a plurality of holders for respectively alternative holding of a closure element or an air-to-air heat-exchanger cassette, wherein the air-to-air heat-exchanger cassettes are designed such that, during operation of the cooling arrangement, a first fluid flow, which is connected to the functional area, is formed through the respective air-to-air heat-exchanger cassette in each case and a second fluid flow, which is separate from the first fluid flow and is connected to environmental air in the electrical or appliance cabinet, is in each case formed along the longitudinal axis in each of the air-to-air heat-exchanger cassettes which are arranged in one of the plurality of holders, in order
  • two of the plurality of holders are designed such that the air-to-air heat-exchanger cassettes which are arranged in these holders have outlet openings which are at a distance from one another along the longitudinal axis, and/or inlet openings, which are at a distance from one another along the longitudinal axis, for the respective first fluid flows. It is thus possible to deliberately form first fluid flows in different areas along the longitudinal axis of the elongated cross-sectional area of the functional area. Fitting of the cooling arrangement with air-to-air heat-exchanger cassettes can thus be chosen to match the items fitted in different areas along the longitudinal axis of the functional area.
  • the plurality of holders are arranged such that during operation the first fluid flows are in each case formed in air-to-air heat-exchanger cassettes which are arranged in adjacent runs of the plurality of holders along the longitudinal axis, and these fluid flows are directed in opposite directions parallel to the longitudinal axis. This means that the first fluid flows flow in opposite directions in the air-to-air heat-exchanger cassettes which are arranged adjacent.
  • the cooling arrangement therefore comprises at least one first fan arranged between adjacent holders.
  • the first fan which is arranged between the two adjacent holders is controlled as a function of whether air-to-air heat-exchanger cassettes are fitted in these holders. If, for example, only one holder is fitted with an air-to-air heat-exchanger cassette, then the first fan can be operated with a low flow rate.
  • a first fan such as this arranged between two holders is a radial fan.
  • the mounting arrangement is in the form of a cover element on the functional area.
  • the mounting arrangement is designed such that it hermetically seals the functional area of the electrical or appliance cabinet at the top. This ensures that the functional area is completely dust and moisture proof, within the meaning of the chosen IP degree of protection. Furthermore, optimum heat dissipation and control of the first fluid flows in the functional area are possible.
  • the air which is heated in the functional area (internal area) of the inner housing rises upwards. The highest temperatures of the surfaces which bound the internal area therefore occur on the cover of the functional area.
  • a cooling arrangement can therefore be particularly effectively formed on the cover, or may be in the form of a cover element.
  • the inner housing has a frame which is created from profiles and generally has planking on the outside.
  • the planking with inner walls and a cover is provided in such a way that the internal area is sealed against dirt, moisture and fluid exchange.
  • the cooling arrangement is in the form of a cover element
  • the mounting frame has a circumferential contact surface which can be mounted on the frame.
  • electrical or appliance cabinets have a functional area with a rectangular shape which is elongated along the longitudinal axis of the cross section.
  • the mounting arrangement therefore has a circumferential rectangular elongated contact surface and the outlet openings of the air-to-air heat-exchanger cassettes which are arranged in the adjacent runs of the plurality of holders face opposite short end faces of the rectangular contact surface.
  • the contact surface is designed such that it rests on the frame, which is formed from profiles, of the functional area and can be attached by attachment means.
  • circumferential seals can be introduced into the frame or frame profiles of the functional area. Alternatively, these seals can be integrated on or in the contact surface of the mounting frame.
  • the outlet openings of the air-to-air heat-exchanger cassettes which are arranged in the adjacent runs of the plurality of holders each point towards the opposite short end faces of the rectangular cross-sectional area of the functional area, then this makes it possible to form different first fluid flows in the interior of the functional area, which are preferably directed downwards along the side walls of the functional area which are arranged on the short end faces of the cross-sectional area of the functional area.
  • Air which in the first fluid flows which has been heated by the appliances and installations in the functional area is sucked in in the center between the air-to-air heat-exchanger cassettes which are arranged in adjacent holders and is passed via guide plates to the inlet openings of the air-to-air heat-exchanger cassettes.
  • An arrangement such as this offers the advantage that, even if one fan fails, the first fluid flows are maintained as a circulation between the air-to-air heat-exchanger cassettes since the outer side walls, which bound the functional area, are cooled by adjacent environmental air from the outside, which enters between the functional area wall and an outer housing. There is therefore an air flow directed downwards in the interior of the functional area, adjacent to the functional area side walls. The heated air rises in the interior, probably in the center, of the functional area upwards and enters the air-to-air heat-exchanger cassettes.
  • the air-to-air heat-exchanger cassettes have channels which are oriented vertically and parallel to the longitudinal axis of the mounting arrangement, through which channels one of the first fluid flows and one of the second fluid flows flows alternately, horizontally transversely with respect to the lateral axis. This ensures particularly optimum heat transfer, even when, for example, the fan which maintains the first fluid flows fails.
  • the holders and the air-to-air heat-exchanger cassettes are preferably designed such that the channels of the air-to-air heat-exchanger cassettes through which the second fluid flows flow, that is to say environmental air, are directly adjacent to the functional area, at least on one end surface of the channels, or at least make thermal contact with a boundary surface of the functional area.
  • second fans which each drive or assist one of the second fluid flows, are arranged, preferably oriented on the longitudinal axis of the mounting arrangement, at mutually averted ends of the air-to-air heat-exchanger cassettes which are arranged in adjacent runs of the plurality of holders.
  • the second fans are preferably radial fans.
  • the second fans are, in one preferred embodiment, mounted tilted with respect to a horizontal installation position. Ends of the rotation axes which point upwards, that is to say towards the outer roof, are designed to be further away from the holder along the longitudinal axis of the mounting arrangement than the ends of the rotation axes which point downwards, towards the internal area.
  • the rotation axes of the second fans are therefore not oriented vertically.
  • the upper ends of the rotation axes of second fans which are associated with two adjacent holders are tilted in opposite directions from the vertical. The tilt is most easily provided by using mounting supports of different height. The higher supports face the holder, and the lower supports are averted from the holder. Environmental air can therefore be inducted into the radial fan better from the averted side.
  • the mounting arrangement preferably has depressions which (during operation) are arranged or formed under the contact surface of the mounting arrangement or under a plane on which the air-to-air heat-exchanger cassettes are arranged and placed.
  • the depressions are preferably in the form of troughs.
  • these depressions are preferably adapted such that the depth dimensions of the depressions do not exceed the profile thickness of the profiles.
  • First fans which suck in cooling fluid which has been heated in the internal area or functional area and feed into the air-to-air heat-exchanger cassette or cassettes are preferably arranged in a raised area with respect to a contact surface of the mounting frame or a contact surface of the air-to-air heat-exchanger cassettes.
  • a first fan such as this is in the form of a radial fan into which cooling fluid which has been heated in the internal area flows from underneath from the internal area, if appropriate through a grid, in order to avoid unintended actions on the first fan during operation in the event of maintenance work, and is supplied at the side to the air-to-air heat-exchanger cassette or cassettes.
  • a rotation axis of the first fan, which is in the form of a radial fan, is therefore aligned vertically during operation.
  • the cooling arrangement comprises an outer roof which closes the electrical cabinet or appliance cabinet at the top, in which case the air-to-air heat-exchanger cassettes and the closure elements are matched to the outer roof such that they prevent the outer roof from bending in when forces act on the outer roof from above on the outside. This ensures that the cooling arrangement always operates.
  • the air-to-air heat-exchanger cassettes and the closure elements are thus designed to be sufficiently robust that they can support the outer roof. This means that the strength on outer roof can be reduced and a portion of the structural robustness of the outer roof can be transferred to the air-to-air heat-exchanger cassettes or alternatively to the closure element inserted into the holders.
  • the cooling arrangement with the outer roof forms a roof module.
  • the first and second fans are preferably in the form of radial fans. This results in the cooling arrangement and an outer roof arranged above it having a flat physical shape.
  • the fans in one embodiment are each surrounded by guide elements which drive air that has been sucked in by the fans in and/or into the corresponding channels of the air-to-air heat-exchanger cassettes.
  • the outer roof and/or the side walls of the outer housing are preferably formed in vertical sections with openings that are referred to as gills, in order to allow fluid of the second fluid flows to flow in and out.
  • All the fans that is to say one or more first fans which are arranged in the functional area and second fans which drive second fluid flows of environmental air, are in one preferred embodiment driven and/or controlled via a common control device which faces the functional area.
  • second fans can therefore easily be fitted to the mounting arrangement and can be supplied with electrical power, in order to drive the second fluid flows.
  • the air-to-air heat-exchanger cassettes are designed such that, in conjunction with the outer roof, an inlet-flow area of the air-to-air heat exchanger cassettes is in each case separated from an outlet-flow area. This prevents the heated environmental air which emerges from an air-to-air heater-exchanger cassette from once again flowing into the same or an adjacent air-to-air heat-exchanger cassette. This ensures optimum cooling performance at all times. Only cool environmental air, which has not yet been heated, in each case flows as the second cooling fluid into the air-to-air heat-exchanger cassettes.
  • the plurality of holders are two holders which are designed such that, when two identical air-to-air heat-exchanger cassettes are arranged in the two holders, the first fluid flows are formed in the functional area such that they cool different areas, which are of the functional area.
  • the fans that are used are each arranged in front of inlet openings of the air-to-air heat-exchanger cassettes and blow the respective fluid flows into the air-to-air heat-exchanger cassettes.

  • the appliance cabinet 1 has a cross-sectional shape which is elongated along a longitudinal axis 9 , preferably a rectangular cross-sectional shape.
  • the functional area side walls 8 therefore preferably comprise short end faces 8 a and a longitudinal side wall which is frequently referred to as a rear wall 8 b.
  • a front longitudinal side wall (not illustrated) facing the viewer is preferably in the form of a door.
  • the functional area is also dust proof and fluid proof, and is therefore also sealed to be moisture proof, with respect to the base, that is to say downwards.
  • the functional area 4 is sealed by a mounting arrangement 11 of a cooling arrangement 12 .
  • the mounting arrangement 11 is designed such that it forms a contact surface 46 which rests on the profiles 7 of the frame 6 and hermetically seals the functional area 4 such that it is dust proof and fluid proof.
  • individual components of the cooling arrangement may “penetrate” or “project” into the functional area 4 . This means that they are arranged underneath the contact surface 46 during operation.
  • the mounting arrangement 11 of the cooling arrangement 12 is designed such that it can be attached and locked to the frame 6 with the aid of attachment means. Attachment means that are known to a person skilled in the art may be used as attachment means.
  • the mounting arrangement can be screwed to the frame 6 .
  • the mounting arrangement 11 comprises two holders 13 , 14 in which air-to-air heat-exchanger cassettes 15 , 16 are arranged. These are arranged in the holders 13 , 14 in such a way that it is impossible for fluid and/or dust to enter the functional area or to emerge from the functional area.

  • First fluid flows 25 , 26 are therefore formed in the air-to-air heat-exchanger cassettes 15 , 16 and are directed parallel to the longitudinal axis 9 or a longitudinal axis 27 of the mounting arrangement, in opposite directions.
  • the first fluid flows 25 , 26 flow through channels, which extend parallel to the longitudinal direction and vertically, in the air-to-air heat-exchanger cassettes 15 , 16 .
  • Second fluid flows 28 , 29 flow in the opposite direction through the air-to-air heat-exchanger cassettes 15 , 16 .
  • These are driven by second fans 30 , 31 , which are preferably likewise in the form of radial fans.
  • the second fans 30 , 31 are mounted inclined so as to make it easier for environmental air to flow into the fans 30 , 31 .
  • Further guide plates 32 , 33 are arranged above the radial fans and supply the air to the further inlet openings 34 , 35 of the air-to-air heat-exchanger cassettes 15 , 16 .

  • Lower horizontal walls 65 of the channels 63 are preferably directly adjacent to the functional area of the inner housing, or make thermal contact with the functional area via a contact surface 66 of the mounting arrangement 11 (see FIG. 2 ). This ensures at least reduced cooling of the functional area even in the event of failure of the first fan.
  • a control device which is arranged on the side of the mounting arrangement facing the functional area, is preferably designed such that it supplies an electrical power and regulates the first fan and the second fan.
  • the control device is preferably designed such that a speed of revolution of the first fan, which sucks in heated air from the functional area, is defined as a function of the items fitted in the adjacent holders. If only one holder is occupied by an air-to-air heat-exchanger, then a reduced rotation speed is required from the first fan when the further environmental parameters are otherwise identical than if an air-to-air heat-exchanger cassette were fitted in both holders.
  • the described embodiment is only of an exemplary character.
  • further holders can be provided along the longitudinal axis of the mounting arrangement. This makes it possible to provide further areas, which are adjacent along the longitudinal axis, of the functional area with a separate cooling air supply. Since cooling air enters the functional area at different points along the longitudinal axis, different cooling flows can be passed to appliances and devices which require special cooling, via guide plates which are fitted in the interior of the functional area. Other parts of the internal area which may not require special cooling can be largely separated by guide plates (not illustrated) in such a way that the internal area air circulates effectively in the area in which the heat is produced by the installed appliances and installations.
