Definitions
- the invention relates to a heat exchanger, in particular a condenser for motor vehicle air conditioning systems according to the preamble of patent claim 1.
- Condensers for air conditioning systems, especially for motor vehicles are known in various designs, including as a so-called capacitor module, in which a collector for the refrigerant with the capacitor is integrated into a heat exchanger.
- a capacitor module was in its basic structure by the DE 42 38 853 A1 known.
- the collector is designed with one of the two manifolds as a so-called double tube, ie the two tube chambers are immediately adjacent to each other and communicate on the refrigerant side through openings.
- a dryer element is arranged, which is flowed around by the refrigerant.
- the tubular collector is closed by a screwable closure plug arranged in the bottom region.
- header and collector are also formed as a double tube, wherein the collector is closed in its upper part by a screw cap.
- An arranged in the collector dryer unit can thus be removed and replaced.
- a pressure sensor or a pressure switch is arranged, which is connected via a bore in the screw with the interior of the collector in communication and thus can detect the pressure of the refrigerant in the collector.
- the collector is composed of a welded tube and a preferably extruded profile piece.
- the mechanically machinable profile piece has two transfer openings, which produce a connection on the refrigerant side to the adjacent collection tube.
- a threaded plug is screwed into the end face of the profile piece, in which a dryer-filter unit is clipped.
- an expression is arranged with a contact surface on which the collector rests and is pre-fixed by tack welds for subsequent soldering. Between collector and manifold a gap is left to prevent heat input from the manifold into the collector.
- a sealing plug for a collecting container of a capacitor has become known.
- the plug seals the interior of the collector via O-rings to the outside and is secured by a snap ring.
- a snap ring By loosening the snap ring of the plug and thus a collector located in the dryer can be removed and replaced.
- a capacitor module which has a consisting of a pipe and a profile piece collector.
- Collecting tube and collector are connected to each other in the upper part by an element designed as a double lid, wherein between collector and manifold also a gap is left.
- collecting tube and collector are connected via collars, which engage in transfer openings in the profile piece.
- the known refrigerant condensers or capacitor modules are arranged in the front engine compartment of a motor vehicle and flows through cooling air.
- the capacitor is connected to another heat exchanger, eg. B. attached to a coolant radiator, by means of fastening elements which are arranged either on the condenser or on the adjacent heat exchanger.
- a second profile piece is provided, which is connected to the pipe section.
- profile pieces are arranged on both end faces of the pipe section, which are preferably extruded, d. H. can be produced from extruded profiles.
- the extruded profile is formed as a hollow profile and has an inner diameter which corresponds to the outer diameter of the tube, so that both parts are first joined and then soldered.
- the profile piece can be designed as a fastening element, wherein preferably a fastening tab or plate is part of the extruded profile. Further, the profile piece may be formed as a spacer and connecting element to the adjacent manifold, wherein preferably provided to the shape of the collecting tube bearing surface is provided, via which both parts are soldered together.
- the profile piece can be used as a final part and a detachable lid, z. B. a screw cap or a stopper take up.
- a collector located in the dryer element can be removed and replaced.
- the dryer element can also be removed from the opposite, ie from the lower side.
- the first and the second profile piece can be produced from the same extruded profile. This results in the advantage that only one tool (extrusion die) or the same semi-finished material can be used. This lowers the manufacturing costs. Both profile pieces are then machined differently depending on the purpose, for. B. by drilling, milling or punching.
- the second profile piece can also be designed as a sensor part, d. H. to be processed for receiving a sensor, preferably a pressure sensor.
- a sensor preferably a pressure sensor.
