  • the present invention has for its object a Generic refrigerant collector to improve so that its assembly and maintenance are made easier.
  • the collection container is from one heat-insulating layer and enclosed on the outside the layer are devices for holding the refrigerant collector educated.
  • Such a refrigerant collector becomes an undesirable one excessive heat absorption largely avoided and thus the effectiveness in the evaporation of refrigerant and the overall performance of the refrigerant collector significantly increased.
  • This alone makes the performance of a refrigerant collector according to the invention increased significantly.
  • the heat-insulating layer advantageously has on its inside Ribs to form the air gap.
  • the air gap can be easily and inexpensively because they save material.
  • the weight can be kept low.
  • the heat insulating layer is as Insulated thermal container.
  • the assembly of the Refrigerant collector is simplified in this way because the Collection container only in the heat insulation container must be used.
  • the heat insulating container serves at the same time as insulation and as a supporting body for the Collection container.
  • the heat insulation container includes a Lower part, in which the collecting container can be inserted, and a lid-shaped top, the top especially preferably by means of snap locks on the lower part is attached.
  • the Collection container and the heat insulating container are cylindrical. This enables inexpensive production of these parts.
  • the lower part preferably has a dome-shaped at the lower end Bottom open and is open at the top.
  • This Training will be the strength and stability of the heat insulating Layer increased in its lower area.
  • the strength and stability also contribute to that in the lower part the ribs at the bottom are essentially radial and at the Cylinder wall extend essentially in the longitudinal direction.
  • the collection container can with such a final formation of the ribs in the lower part without difficulty into the lower part or be used.
  • a condensation drain opening is arranged no risk of getting between the container and the heat-insulating Layer of condensation can accumulate.
  • this Upper part on an upper end surface in which the passage opening is trained.
  • the ribs preferably taper towards the lower end and towards the cylinder wall, causing the top to be put on on the collection container or the insertion of the collection container considerably simplified in the top part of the heat insulating container becomes.
  • the diameter in the upper and lower part of the smallest inner circle described by the ribs is equal to the outside diameter of the collecting container. This ensures a secure hold of the collection container in the heat insulation container, whereby every radial relative movement of the Collection container to the heat insulation container and thus any Shock loads or even the emergence of a noise source is avoided.
  • the devices are in a favorable further development of the invention to hold the refrigerant collector on the lower part of the Insulated thermal container attached.
  • the assembly of the refrigerant collector is further simplified.
  • the lower part can first attached to the bracket, and then the Collection container inserted and the upper part put on.
  • When servicing or repairing the refrigerant collector if necessary only the upper part removed and the collection container be taken out of the lower part, whereby but the lower part remains in the holder. Maintenance or repair times can be reduced as a result.
  • the Devices for holding the refrigerant collector each formed as pocket-shaped receptacles, in each of which Holder is insertable.
  • the refrigerant collector can use it can be securely attached using a simple plug-in device.
  • the pocket-shaped ones very particularly preferably have Recordings each have an opening at the bottom, in which the holder is insertable.
  • the heat insulation container must can only be attached to the holder from above, to be securely fastened, for example, in a motor vehicle his.
  • the pocket-shaped receptacles preferably each have an opening at the top that is smaller than the opening is at the bottom and through which a section of the holder can be passed through.
  • the refrigerant collector 1 shown in the figures is part a motor vehicle air conditioning system.
  • the refrigerant collector 1 has a collecting container 2 and a heat insulating container 3, which the collecting container 2nd encloses and is held by brackets 4, which on the Bolted (not shown) body of the motor vehicle are.
  • the heat insulating container 3 is composed of a lower part 5 and one Upper part 6 formed, both substantially cylindrical are trained.
  • the thermal insulation container has on its inside 3 both in the lower part 5 and in the upper part 6 ribs 7, which abut the collecting container 2.
  • the Free space between the ribs 7 forms an air gap 8 between the collecting container 2 and the wall 9 of the heat insulating container 3 out.
  • the inside diameter of the wall 9a of the Lower part 5 agrees with the inner diameter of the wall 9b of the upper part 6, so that both walls 9a, 9b their insides are flush with each other.
  • On the outside overlaps the upper part 6 with its lower end Lower part 5.
  • ribs 7a formed on the floor 13 - starting from the condensation drain opening 14 - radial and in the area of cylindrical wall 9a extend in the longitudinal direction of the cylinder.
  • the curve shape of the dome-shaped bottom 13 and of the ribs 7a formed on the bottom 13, which are constant Have height is the curve of the lower end adapted to the collection container 2, so that continuously the inner edge 15 of the ribs 7a formed on the bottom 13 lies on.
  • the distance between the radially inner ends 16 of these ribs 7a is larger, for example twice as much large than the diameter of the condensate drain opening 14, whereby the condensed water can run off unhindered.
  • the on of the cylinder wall 9a formed ribs 7a run to this and almost to the connecting joint 17 with the upper part 6 tapered to a point, for example at about 168 mm high lower part 5 and at about 4.5 mm high ribs 7a Inclination can be 1.5 °.
