  • This control cabinet has a combined air-liquid cooling system, on the one hand cooling air passes through an air inlet plate in the cabinet interior.
  • a cooling device comprises a heat sink arranged on a system component group and a liquid distributor, which is in flow communication with the heat sink via a feed line and a return line.
  • the liquid distributor is arranged outside in the front area of the control cabinet.
  • the invention is therefore an object of the invention to provide a generic cabinet that meets all the above requirements, while allowing a simpler, modular design and ensures greater reliability.
  • the air conditioner side is arranged below the system components and a cold and a hot runner to the front or back are formed. This can be achieved without additional lateral space cooling of the 19-inch system components or bays with a defined cold and hot runner and forced guidance of cold air flow through the system components, the system components are coated above and below the cold air flow. Even if the rear wall or door and / or the side walls of the cabinet are removed or opened, there is no break in the cold air flow.
  • An embodiment of the invention provides that the air conditioner is designed as a plug-in unit. This allows for easy replacement, for which only one of the insertion opening occlusive aperture must be removed.
  • a preferred embodiment of the invention provides that the system components in the horizontal and vertical position are inserted into the housing, wherein the vertically inserted system components are arranged in both sides of the horizontally inserted system components housing compartments. It is hereby exploited over the horizontally inserted system components larger width of the air conditioner to achieve optimized placement of the cabinet volume to accommodate a maximum number (preferably 50) of system components. Because the housing compartments only take the space available anyway by the width excess of the air conditioner. According to an advantageous proposal of the invention has - based on each of the side walls of the cabinet housing - the one housing compartment has a greater depth than the other housing compartment. The width excess of the air conditioner is thus optimally utilized by the division of the housing compartments with different depths.
  • the system components or bays in edgewise position with their narrow end faces inserted in the insertion direction and side by side, while in the less deep housing compartment, the system components or bays in contrast rotated by 90 ° in series behind the other flat lying inserted.
  • a preferred embodiment of the invention provides that both the vertical profile struts and the horizontal profile struts are formed uniformly and have a cross section in an inner and an outer profile strut chamber dividing partition, which isolates the housing interior to the environment.
  • the inside of the cabinet is thus subject to no external, adverse for the circulation of air, but especially for the dust and splash water tightness adverse influences. Because the created by the partition, circumferential separation level is the cabinet inside safely encapsulated.
  • the closed design of the profile struts also ensures a high resistance torque and high torsional stiffness.
  • Winkeleck for example, a Zink réelleguss- or steel casting, two mutually orthogonal profile approaches and a downwardly angled profile approach, with the profiled approaches immerse in the outer profile strut chambers, can be easily close the open, abutting ends of the profile struts and the Winkeleck thoroughlye connect to the profile struts for a secure cohesion.
  • an embodiment of the invention provides that holes are provided for attachment to the vertical and horizontal profile struts in the walls formed by angled webs of the vertical profile struts and horizontal profile struts rows for attachment of attachments and in the profile approaches the Winkeleck Sharings.
  • the rows of holes of the profile struts are on the one hand to the attachment of the housing cover already described holes in the webs or walls of the outer profile strut chamber and on the other hand to rows of holes in the webs or walls of the inner profile strut chambers for attachment of the interior organization (19-inch system components , Shelves, cable fasteners or the like) of the control cabinet or computer rack.
  • At least the holes of the rows of holes of the vertical and horizontal profile struts are formed reinforced material with sleeve-like passages. This contributes to the fact that the self-tapping screws used to attach the attachments do not spin even after repeated use.
  • the free ends of the profile projections of the angle corner piece are provided with inlet slopes, the simple insertion of the angle corner piece is supported in the profile struts and the outer profile strut chambers.
  • the angle corner piece is formed with a vertically extending core hole. This allows the simple, subsequent attachment of feet, rollers, eye bolts or the like.
  • FIG. 1 is a perspective overall view of a without wall paneling or doors or the like shown assembled from profile struts housing frame of a cabinet or computer rack with bottom-mounted air conditioner;
  • FIG. 2 shows the housing frame according to FIG. 1 in front view
  • Figure 3 is a perspective view as a detail of the marked in Figure 1 with "X" corner region of the profile strut housing frame.
  • Fig. 4 is a representation corresponding to Figure 3 with the other hand for the connection of the profiles also inserted Winkeleck College.
  • Figure 5 as a detail in an overall perspective view of the inserted into the abutting profile ends of Figure 4 Winkeleck brainstorm.
  • a computer rack or cabinet 1 is in Figs. 1 and 2, essentially only the housing frame formed from profile struts or the housing 2 with it below the system components 3, of which in horizontal installation position only a few are indicated, arranged, designed as a plug-in unit Air conditioner 4 shown. Its fans 5 ensure inside the cabinet for an air circulation for cooling the system components 3, which are lapped by the indicated by arrow 6 cooling air streams. Because these branch off from an illustrated by the upwardly facing arrows 7 total air flow of a trained inside the cabinet cooling channel 8 and then fall in the inside of the cabinet opposite formed hot runner 9 according to the downward arrows 10, so that they according to arrow 11 back in the air conditioner 4 and thus enter the new cooling circuit.
