Description

  • The invention relates to a control cabinet comprising a body with side walls, floor, rear wall, door and a roof cover provided with a passage opening and a variable in depth parallel to the rear wall therein usable wiring frame or a mounting plate having a lower passage opening for mounting electrical or electronic components and with a cold air generator mounted above its roof covering with a hot air intake opening from the control cabinet and a cold air outlet opening in the control cabinet.
  • It is known a cooling arrangement for arranged in a cabinet electrical equipment, DE 10 2009 054 011 B4 in which an air conveying device and an air cooling device are provided within a control cabinet, by means of which air in the interior of the control cabinet is circulated. However, this known cooling arrangement is not very variable and also requires a considerable volume of space within the control cabinet. Further known is a control cabinet with an air conditioner, DE 37 10 566 A1 in which the air conditioner can be placed on quick release closures on a cabinet, the roof covering is provided with corresponding passage openings, this known construction is not very flexible, since the air conditioner constructively defined suction and exhaust openings, so that hardly a changed interior design and Equipment of a control cabinet can be reacted.
  • The object of the invention is to provide a cabinet, which is equipped with a variably installable wiring frame or mounting plate with lower passage opening and with a space-saving arranged cold air generator in which a targeted steering of the air flow from the cold air generator in the cabinet to the built-in switching elements along and back into the cold air generator is made possible. Furthermore, an optimal circulation of the air in the cabinet should be achieved to allow a washing around a stocked with electrical or electronic components wiring frame or a mounting plate and to minimize the risk of hot spots by generating a cooling air flow significantly.
  • The solution of this object is achieved in conjunction with the features of the preamble according to the invention in connection with the technical features of the characterizing part of the first protection claim, in particular by the fact that between cold air generator and roof cover an air guide is provided with an aligned on the intake of the cold air generator passage for the Warm air from the control cabinet and a passage for the cold air into the cabinet, wherein the air guide cassette has a flange to the roof cover and in two offset by 180 degrees positions, with the exhaust port and the passage channel to the front or rear, mounted on the cabinet.
  • A particular advantage of this invention is that even the possible reversal of the air duct cassette and the cold air generator allow a variety of air routing variants, the adjustable at a distance from the rear wall wiring frame or mounting plates contribute significantly, so that the used cold air generator can work very efficiently and their actual required power compared to the known prior art can be significantly reduced. Insufficient air circulation is thus avoided and the risk of hot spots is significantly reduced, so that during subsequent operation neither components of the control cabinet nor as a result of this whole plant components can fail. This advantage is also achieved in that it can be dispensed with any flow-obstructing cable channels.
  • Further advantageous embodiments of the subject of the invention will become apparent with and in combination from the following subclaims.
  • The fact that the cold air introduced in the area between the rear wall and wiring frame or mounting plate from top to bottom in the cabinet and at least in the lower area deflected by a lower passage to the front and heated up again withdrawn from the cabinet or in the reverse position of the Air duct cassette and the cold air generator in the area immediately behind the door from top to bottom introduced into the cabinet and deflected only in the lower area to the rear or to the middle and upwards between the electrical or electronic components, this cooling, pulled up from the cabinet are already resulting in two completely different flow variations, which can be further differentiated according to a further preferred embodiment of the invention, in which are provided in the Luftleitkassette air baffles that are adjustable in angle or distance adjustable, as well as austau schbar or supplemented, so that always optimal cooling of the components installed in a cabinet can be achieved.
  • The cold air generator is advantageously made of an air-water heat exchanger, the Internal air of the cabinet circulates, the cold air generator is supplied via inlet and return connections with the cooling medium water, so that an undesirable heating of a room can be avoided, especially if several cabinets are arranged therein, advantageously on a cabinet and a plurality of air ducts, each with a Cold air generator or on a Luftleitkassette also several cold air generator can be arranged side by side, which can be assigned side by side arranged individual cabinets or even a wide control cabinet, so that here are the possibilities of variation very diverse.
  • The use of an air-water heat exchanger is not necessarily fixed, it could also other technologies such as air-to-air heat exchangers are used or compressor cooling devices, as well as different power from 0.5 to 5 KW can be set up, but without here Needlessly high performance in order to achieve a very effective effect.
  • Also, the wiring frame height, width, depth vary greatly, as well as the density of the mounting rails arranged thereon and also its mounting position in the cabinet, which can be selectively directed to thermal critical points by attaching additional small air baffles partial air flows from the cold air stream. A mounting plate needs at least in one embodiment with injected between the mounting plate and the rear wall cold air flow in the lower part of the cabinet a large passage opening or must be stored offset from the ground up to let the cold air flow can reach the front of the cabinet.
  • Further variations exist in the embodiment of the cabinet itself, which may vary in height, width and depth and may also have more interior fittings, as well as the construction of Luftleitkassette in height, width and depth may vary, as well as their mounting position on the cabinet, as well how the angle of attack and the number of air baffles can be designed differently.
  • An exemplary embodiment of the invention is described in more detail below with reference to drawings. Show it:
  • 1 a sectional partial view of the upper portion of a cabinet,
  • 2 an air duct cassette in spatial representation,
  • 3 a sectional view of a control cabinet,
  • 4 a view of a wiring frame and
  • 5 a sectional side view of a complete cabinet.
  • The control cabinet 1 consists of a frame with side walls 2 a floor 3 , a back wall 4 , a door 5 as well as from a roof cover 7 with passage openings 6 , as well as from an attached flue cassette 15 with air baffles 18 that has a passageway 16 for out of the cabinet 1 withdrawn warm air 12 generate as well as a passageway 17 for in the control cabinet 1 blown cold air back 14 ,
  • On the air duct cassette 15 is a cold air generator 10 arranged, which is designed here as an air-water heat exchanger and the supply and return ports 19 is supplied with coolant. The warm air 12 is through suction openings 11 and a passage 20 the air guide cassette 15 into the cold air generator 10 sucked in and then the cold air 14 over a passage 21 the air guide cassette 15 again through the passageway 16 in the control cabinet 1 into promoted.
  • 1 shows an embodiment with far towards the rear wall rearwardly arranged wiring frame 8th and a supply of cold air 14 in the field of the door 5 of the control cabinet 1 and with a suction of hot air 12 in the area in front of the wiring frame 8th ,
  • 5 on the other hand, one points further forward from the back wall 4 in the interior of the control cabinet 1 advanced wiring frame 8th with a supply of cold air 14 between the back wall 4 and the wiring frame 8th and a deflection of the air in the bottom area through a lower passage opening 9 , as they would have to have a drawing plate not shown in the drawing.
  • The air duct cassette 15 of the 5 is 180 degrees offset to the air duct cassette 15 gem. 1 on the control cabinet 1 arranged, as well as the cold air generator 10 so that the heated air 12 here over a large area in the upper area of the control cabinet 1 in front of the wiring frame 8th or a mounting plate through the Luftleitkassette 15 into the cold air generator 10 is transported.
  • As in 2 is shown, the Luftleitkassette 15 in the upper area to the cold air generator 10 arranged outlets 20 . 21 for warm air 12 or cold air 14 on, as well as three air baffles 18 and a mounting flange 22 with which the Luftleitkassette 15 on a roof cover 7 a control cabinet 1 , is attachable.
  • As in 3 is shown, which is a sectional view of a cabinet 1 according to the 1 represents, it would be conceivable here the cold air 14 also behind the wiring frame 8th between this and the back wall 4 of the control cabinet 1 blow in, so that the final design can also be made dependent on the assembly of the control cabinet.
