Definitions
- Heat exchanger in particular condenser for air conditioners
- the invention relates to a heat exchanger, in particular for air conditioning systems, in particular of motor vehicles according to the preamble of patent claim 1 - known from EP 1 439 367 A1.
- the invention also relates to a method for producing a heat exchanger according to the term of claim 5.
- a condenser consists essentially of a condenser block, which is constructed of flat tubes and corrugated fins, as well as arranged on both sides of the block manifolds, which are in communicating connection with the tubes of the condenser block.
- the headers and the flat tubes of the condenser are flowed through by a refrigerant, which is supplied to the condenser from a refrigerant circuit via connecting flanges and withdrawn again.
- the flanges are prefabricated separate parts, which are connected on the one hand with a header of the condenser and the other with a refrigerant line.
- EP 1 150 088 A2 discloses a connection between a refrigerant connection flange and a collector tube of a condenser, wherein the refrigerant flange has an integrally formed nozzle which is inserted into a bore of the collector tube and widened by means of a punch such that a fixation and anchoring the flange is reached on the manifold. Subsequently, the soldering of manifold and flange. This type of connection is costly, especially because of the formation of the flange.
- the collar inserted into a bore of the connecting flange is plastically deformed by means of a polygonal punch such that a fixing takes place.
- Polygonal stamping is to be understood as meaning a forming or expanding tool which does not have a circular cross-section but a polygonal cross-section which extends into Direction slightly tapered towards a point.
- the polygonal punches may have three, four or six surfaces which are tapered in the shape of a pyramid or designed as a truncated pyramid. This tool deforms the collar in the connecting flange.
- the prepared for subsequent soldering, completed heat exchanger can be soldered due to the fixation of the invention without further Löt Anlagen in a soldering oven, so that a Dichtlötung between the collar and the flange is achieved,
- the inner cross section of the collar has a polygonal, preferably a hexagonal, cross-section - like a hexagon socket.
- the manifold is in two parts, d. H. formed with a lid and bottom part, wherein the collar is integrally formed on the lid.
- the object of the invention is also achieved by a method having the features of claim 5.
- the collar formed from the collecting tube is inserted into the bore of the connecting flange and then fixed by widening by means of the polygon punch. Connection flange and manifold cover are then sufficiently firmly connected together that then soldering can be done without further aids.
- Fig. 2 mounted on the manifold of the condenser flange
- Fig. 3 is a view from the inside of the manifold in the region of the connecting flange.
- Fig. 1 shows a corner cutout of a capacitor 1 for an air conditioner, not shown, of a motor vehicle.
- the condenser 1 has a condenser block 3 consisting of flat tubes 2 and ribs, not shown, which is connected to a collecting pipe 4.
- Another manifold on the opposite side of the capacitor block is not shown.
- the manifold 4 is formed in two parts, d. H. it has a bottom 5 and a cover 6, which have an approximately semicircular cross-section and are set in one another.
- the end face of the collecting tube 4 is closed by an end wall 7 and forms a cavity which communicates with the flat tubes 2.
- From the cover 6, a collar 8 is integrally formed, d. H. by punching punching.
- connection flange 9 is shown, which is to be connected to the manifold 4.
- the connection flange 9 has a through-bore 10, which on the one hand is connected to a refrigerant connection line, not shown, and on the other hand to the collar 8 of the collection tube 4.
- the items shown in the drawing 2, 5, 6, 7, 8, 9 are made of aluminum or aluminum alloys and are soldered together.
- the connecting flange 9 is placed with its through hole 10 on the collar 8 of the collecting tube 4. This is already a preliminary positioning and centering of the connection flange 9 on the manifold 4th
- Fig. 2 shows the flange 9, placed on the cover 6 of the manifold 4th
- FIG. 3 shows a view in the direction X on the cover 6, the flow cross section of the collar 8 appearing as a blackened circular surface 8a.
- the circular cross section 8a is deformed by means of a polygon punch, not shown, d. H. is widened in particular with respect to the through hole 10 of the connecting flange 9.
- polygon stamp is to be understood a mandrel-shaped tool which has a non-circular, polygonal cross-section which tapers in the direction of impact, d. H. wedge-shaped or truncated pyramid is formed.
- a deformation of the inner diameter of the collar 8 takes place substantially over the polygon edges, which dig into the material of the collar 8 and press it outward, whereby a pressure is created.
- the cross section of the polygonal punch preferably has the shape of a regular hexagon, although more or fewer corners are possible.
