- the collection container constructed when the housing is designed as a tube with an open end.
- the opening is then formed by the open tube end into which the plug is receivable, is made of plastic, Er.
- the hollow cylindrical plug is made of plastic, it is particularly well suited as a detachable closure of the collecting container, since a plastic for a deformability according to the invention and at the same time sufficient strength for closing the collecting container is readily selectable.
- the plug has a shielding element, which is designed as a metal vapor deposition or paint coating, which is applied at least on the inside of the housing facing side of the plug.
- the plug is integrally formed with the sealant, whereby a mounting cost of the collecting container is reduced due to a resulting reduction in the number of items.
- the sealing means may be injection molded onto the plug, whereby a particularly simple one-piece design of the plug can be realized with the sealant.
- the plug is secured against falling out of the sump by being held in the opening by a circlip.
- a loosening of the retaining ring is prevented from an optionally existing annular groove in the edge of the housing opening by the locking ring is secured by a provided on the stopper, applied to an inner edge of the locking ring locking portion.
- the collecting container according to the invention is used in a heat exchanger with tubes, fins and two headers such that a heat exchange medium, the through flows through the heat exchanger, before, then or during the flow through the reservoir.
- the heat exchanger is designed as a condenser, in which case particularly preferably a dryer is accommodated in the sump.
- Such heat exchangers are through the DE 42 38 853 C2 become known, which hereby expressly belongs to the disclosure content.
- the collecting container according to the invention is used in a refrigerant circuit of an air conditioner with a compression element, a first heat exchanger, a relaxation element and a second heat exchanger to allow a collection of the refrigerant.
- the sump contains a dryer for the refrigerant.
- the compression element is a compressor
- the first heat exchanger is a condenser
- the expansion element is an expansion valve
- the second heat exchanger is an evaporator.
- FIG. 1 a condenser (1) of an otherwise not shown refrigerant circuit for an air conditioner is shown. It has a tube and fin block (10) with tubes (11) and arranged therebetween ribs (12).
- a first manifold (13) is provided with an inlet connection (15) for a non-illustrated compression element, such as a compressor, coming gaseous refrigerant and with a drain port (16) for a likewise not shown expansion element, such as an expansion valve, provided flowing liquid refrigerant.
- the two header pipes (13, 14) are separated by partitions (17, 18, 19, 20, 21, 22, 26, 27) into head pieces (33, 34) communicating with the connections (15, 16) and into intermediate pieces (35, 36, 37, 38, 39, 40, 41, 42) such that the refrigerant from the head piece (33) to the intermediate piece (40) and the intermediate piece (42) to the head piece (34) each have a serpentine path through the condenser (1 ), wherein the flow cross-section with increasing cooling in accordance with the thereby reducing volume of the gaseous and / or liquid Refrigerant is also reduced.
