  • two overflow openings are provided in the lower region, so that they are in fluid communication with each other.
  • a partition wall is arranged in the manifold.
  • a dryer / filter unit that is open over its circumference is used, which is fastened in a groove of the collector by means of a holding means, such as, for example, a circumferential holding rib.
  • the collector is closed at the top and bottom by a lid.
  • the collector is designed as a one-piece tube.
  • the collector is formed by two tubes, which are arranged with the interposition of a ring, the outer diameter of which corresponds to the outer diameters of the tubes, and are connected to each other by means of a sleeve arranged on the outside.
  • the ring is part of a disc-shaped filter with the filter material held by the ring in the appropriate plane.
  • a heat exchanger in particular a condenser, comprising at least one heat transfer area, preferably formed by pipes through which refrigerant flows, in particular flat tubes, and optionally corrugated fins or other elements which increase the heat transferring surface, in which heat is transferred from one medium to another medium, in particular from air to a refrigerant flowing in the flat tubes, a collecting tube and a collector connected to the collecting tube via at least two overflow openings and arranged laterally from the collecting tube, that of the first medium, in particular preferably a refrigerant , Particularly preferably R134a or a refrigerant with corresponding properties, can flow through.
  • a dryer and / or filter unit is used in the collector, which has a ring on the outer circumference - either fixedly attached or integrally formed with the dryer and / or filter unit - which rests with its outer circumference on the inner circumference of the collector.
  • the ring is fixed by the forming of the outer wall of the collector in the same at least in one direction.
  • the ring and the thus firmly connected dryer and / or filter unit is positionally positioned and fixed in the collector so that it does not cause noise due to movements of the dryer and / or filter unit in the collector, especially in the radial direction, can come.
  • the possibly still required fixation in the other direction can be done by fixing the ring in both directions, and / or by a second ring and / or a stop on another component.
  • the collector is preferably formed like a tube with a circular cross-section.
  • rolled or extruded tubes can be used.
  • a post-processing - except if necessary, a deburring after cutting to form a clean contact surface for a closing lid - can be omitted.
  • the inner lateral surface of the tube is formed continuously without deformations or cutouts prior to insertion of the dryer and / or filter unit, hereinafter also referred to as "planar". The same applies preferably also for the outer circumferential surface.
  • one of the occlusive covers may be integrally formed with the tube, so that a subsequent attachment, in particular soldering or optionally also welding, pressing or the like, may be dispensed with.
  • the dryer and / or filter unit is preferably part of a combined dryer / filter unit.
  • the ring which positions the dryer and / or filter unit in the collector, preferably has at least one passage opening for the refrigerant in the collector.
  • a plurality of passage openings is provided, preferably between two and twenty, more preferably between four and twelve, most preferably six or eight.
  • the passage openings are preferably distributed uniformly over the circumference of the ring. Between the passage openings webs are preferably arranged whose width is smaller than the length of the passage openings, i. the total passage area is relatively large. Particularly preferably, at least one passage opening is slot-like, in particular with a slight curvature.
  • At least one passage opening is arranged closer to the inside of the ring than on the outside of the ring. This increases the stability of the ring against deformation (and associated closure) of the passage openings in the case of the dryer and / or filter unit in the collector fixing forming.
  • R134a is preferably used, but any other refrigerant which is suitable for a corresponding heat exchanger due to its characteristics may be used.
  • a combined dryer / filter unit is preferably provided.
  • Granules are preferably provided in the dryer / filter unit, however, another suitable filter material, such as, for example, a fabric, may also be provided.
  • Such a heat exchanger with a collector and dryer and / or filter unit is preferably used as a condenser, which serves the air conditioning of a motor vehicle.
