Abstract

In the pan (10) base (13), an air inlet opening (14) aligns with the warm air outlet of the cabinet. One or more air outlet openings (18) align with cabinet cold air inlet openings. The cooler includes a mounting panel with internal coolant circuit components fastened below it. Pan and panel together form an enclosure for these components, which form a connection between the air inlet and outlets.

Description

  • The invention relates to a floor pan for connecting a roof structure Cooling device with the roof of a control cabinet for coupling the Switch cabinet interior with the inner circuit of the refrigerant circuit Roof-mounted cooling unit.
  • More and more control cabinets require a cooling device in order to Extract warm air from the interior, cool it down and return it to the Supply the interior of the control cabinet with cooling. So-called Roof-mounted cooling units used on the roof or the top wall of the Control cabinet are attached and in air-conducting connection with each other stand. The roof-mounted cooling unit usually consists of a the lower part of the switch cabinet and one of the components of the housing covering the cooling unit working according to the heat pump principle Top. To ensure the function of the cooling unit, the one with the Control cabinet interior coupled inner circle and that with the environment coupled external circuit of the refrigerant circuit as good as possible against each other be decoupled. This requires separators and baffles in the cooling unit complicate and complicate the construction of the refrigerator.
  • It is an object of the invention to a floor pan of the type mentioned create a simple variable air flow between the control cabinet and creates the cooling unit while maintaining a simple construction at the same time the decoupling of the inner circle from the outer circle of the Refrigerant circuit facilitates and effects.
  • This object is achieved according to the invention in that the bottom of the Floor pan at least one with the warm air outlet of the control cabinet aligned air inlet opening and one or more with the cold air inlets of the control cabinet aligned air outlet opening (s) is (are), that the cooling device with a mounting plate the floor pan as the receiving space for the components of the Closes the inner circuit of the refrigerant circuit and that the inner circuit with its components the air inlet opening with the or Air outlet opening (s) connects.
  • The floor pan designed in this way can easily be positioned between the air ducts adapt to the control cabinet interior and the roof-mounted cooling unit and at the same time forms the receiving space for the components of the inner circle, when the complete cooling unit is connected to the floor pan and thereby this closes. The inner circle with its components is now in the Floor pan relocated, coupled to the control cabinet interior and with decoupled from the external circuit of the refrigerant circuit.
  • According to one embodiment, it is provided that the air inlet opening and the Air outlet openings with ventilation grilles, ventilation slats or the like are covered in order to access the To complicate the interior of the floor pan. You can also use the Air outlet openings of the floor pan cold air supplied to the heat-generating points in the cabinet interior can be directed when the Air inlet openings of the control cabinet corresponding air guiding devices take up.
  • According to a further development, it is provided that the floor pan as a condensate Sump is formed, the air inlet opening and the Air outlet openings are surrounded by a condensate protective wall, the height of which then determines the capacity for the condensate in the floor pan can the floor pan the function of a without additional parts Take over the condensate drip pan. It is also prevented that the condensate from the Floor pan can flow back into the cabinet interior.
  • The drainage of the condensate from the floor pan can be done after a Design take place so that it is rectangular and in one Corner area above the floor in each of the abutting side walls Has condensate drain. A condensate drain can be closed be, so that the condensate optionally in the area of one or the other Sidewall can be derived.
  • The attachment of the actual cooling device to the floor pan is easy solved in that the side walls in the area of the open top Mounting holes for attaching the cooling device are provided.
  • To simplify the construction and assembly is another Design provided that on the bottom and on the inside of the Side walls support elements, connecting and sealing elements for the Components of the inner circuit of the refrigerant circuit are molded.
  • It is preferably provided that the floor pan with the ventilation grilles or ventilation slats, the condensate protection walls, the condensate drains, the support elements and the connecting and sealing elements as one-piece plastic injection molded part is formed and manufactured, then the Parts and assembly work significantly reduced.
  • The invention is illustrated by one in the drawing Embodiment explained in more detail.
  • The floor pan 10 shown in the drawing has a rectangular cross section and forms with the floor 13 and the side walls 11 a receiving space for the components of the inner circle - z. B. intake fan and evaporator - the refrigerant circuit, which can be attached to the actual cooling device, which is connected to the side walls 11 of the floor pan 10 , as indicated by the mounting holes 12 . The floor pan 10 is closed and its interior is decoupled from the other components of the cooling device, in particular the outer circle.
  • An air inlet opening 14 is provided in the center of the base 13 , which is aligned with the hot air outlet of the control cabinet and is covered with a ventilation grille 16 . The air inlet opening 14 is surrounded by a condensate protective wall 15 . Around the air inlet opening 14 , one or more air outlet openings 18 are provided in the floor, which are aligned with correspondingly distributed cold air inlets of the control cabinet and are also surrounded by condensate protective walls 19 if the floor pan 10 is simultaneously used as a condensate collecting pan. The air outlet openings 18 can also be covered with a ventilation grille or ventilation slats.
  • As further shown, 11 support elements 20, condensate drains 21 and 22 and connecting and sealing elements can be formed 17 on the bottom 13 and on the inside of the side walls which are integrally formed in a single operation during production of the floor pan 10 in the plastic injection molding process become. The floor pan 10 thus produced is a simple, inexpensive part which takes over all the functions for connecting the control cabinet and the roof-mounted cooling device.
  • The arrangement of two condensate drains 21 and 22 in the area of a corner of the floor pan 10 has the advantage that the condensate can optionally be drained from the floor pan 10 on two sides if a condensate drain 21 or 22 is closed with a stopper.
  • The molded-on elements are designed and distributed in the floor pan 10 such that the components of the inner circle take over the desired connection in the floor pan 10 from the air inlet opening 14 to the air outlet openings 18 and that the input side of the inner circle is decoupled from the outlet side of the inner circle. This ensures that the internal circuit of the refrigerant circuit functions properly.
