Definitions

  • the invention relates to a compressor cooling device according to the preamble of the first claim.
  • an outer housing encompasses an inner container.
  • the outer housing has a base which is designed as a molded plastic part and has an angled section which is formed as part of the rear wall of the device.
  • a deep recess accommodating the motor compressor is molded in one piece and a flat recess on the side.
  • the motor compressor is located in a refrigerant circuit between an evaporator and a condenser, with which it is connected via pipes.
  • the horizontal part of the base forming the bottom of the cooling device is shaped in such a way that an air duct is formed on its underside, which opens into the flat niche part.
  • the shallow niche is used exclusively for ventilation, in particular to cool the condenser located in the area of the rear wall. With this construction, the flow cross-section in the area of the flat niche must be kept clear so as not to prevent the cooling air flow or to permanently disrupt it.
  • the invention is based on the object of taking measures in a cooling device according to the preamble of the first claim, by means of which connecting lines from the motor compressor to the rest of the refrigerant circuit can be guided freely within the housing contour over a length sufficient for assembly purposes.
  • the flat niche part is used to accommodate the part of the pipelines via which the motor compressor is connected to the refrigerant circuit.
  • the pipes are led through a wall of the flat niche part, in particular through the horizontal upper wall, they do not protrude beyond the housing contour.
  • the flat niche part therefore only needs to be dimensioned in depth according to the dimensions of the pipes. Since these pipes only have a small diameter, the usable volume of the inner container to be cooled is only insignificantly limited by the flat niche part, even if the required heat insulation is undiminished in the area of the flat niche part.
  • This construction of the cooling device is particularly advantageous because the section of the rear wall of the device above the niches is occupied on its side facing the inner container with a condenser which is connected to the compressor via one of the pipes.
  • the pipes can all be routed to the components of the refrigerant circuit within the thermal insulation. There is therefore a perfectly smooth finish to the rear of the refrigerator.
  • a cooling device schematically indicated at (1) has a lower section (2) and an upper section (3) of a rear wall of the device.
  • the lower section (2) is provided with a niche part 4, the dimensions of which are adapted to the outer contours of a motor compressor 5 with its electrical connection box 6 and the refrigerant line connections 7, in the region lying to the side of the niche part 4, the section 2 is still flat Niche part 8 equipped, which is much smaller in depth than the niche part 4 and is dimensioned for receiving pipes 9 of the refrigerant circuit.
  • the pipes 9 are connected to the connections 7 of the motor compressor 5.
  • the niche parts 4, 8 merge into one another at their common recessed vertical edge 10.
  • the free length of the pipelines 9 required for the connection to the connections 7 can thereby be guided within the contour of the device 1; they do not have to overlap the opening wheel 11 of the niche parts 4, 8. Therefore, the pipes 9 are passed through a wall, in particular through the horizontal upper wall 12 of the flat niche part.
  • the niche parts 4, 8 are formed in one piece with the lower section 2 of the rear wall of the device and in particular are drawn or injection-molded from plastic.
  • the lower section 2 receiving the niche parts 4, 8 lies with its opening edge 11 in one plane with the remaining section 3 of the rear wall of the device.
  • the sections 2 and 3 are placed close together at their common edge, so that no insulating foam emerges when the space between the inner container of the cooling device 1, not shown, and the rear wall 2, 3 is foamed. This also ensures a continuous, smooth rear wall of the housing.
  • the upper section 3 is designed as a sheet metal wall, which is covered with a condenser coil 13 on its side facing the inner container or the foam insulation.
  • the pipes 9 can therefore be led through the insulating foam not only to the evaporator but also to the condenser 13.
