Definitions
- the invention relates to a heat exchanger, in particular one Refrigerant evaporator, with a soldered block in pairs a U-shaped guide and collecting channels for a heat exchange medium forming, embossed plates, with between the plate pairs arranged corrugated ribs and with at the ends of the block with the interposition of corrugated ribs, plate-shaped Side panels.
- the invention has for its object a heat exchanger of the type mentioned to improve manufacturing technology.
- This object is achieved in that the areas of the side parts in which the collecting channels are located are separated from the other areas by means of a flange and with an embossed profile with a cover plate that closes the last plate forms a chamber that connects to at least one of the collecting channels.
- Such a chamber can be easily in the side parts integrate without the need for additional components become.
- the side part can still be used in the known Way before soldering with the plates and corrugated fins to be put together into a block, which then as a whole in an oven is soldered.
- the chamber formed in this way can be, for example, as a redirection between two or more Collection channels are used. Beyond that it is possible, the profiling with a receiving opening for a connector to be provided so that connections for a supply or Derivation created without the use of additional components become, i.e. can be integrated into one or both side parts.
- Plate (10) forms with the preceding, not shown Plate corresponding to the plate (11) between rotating, adjacent edges of this U-shaped guide, which is why Plates in a not shown, but by the stand known in the art are provided with embossings that have only a relatively shallow depth.
- the plates (10, 11) are in the area of their upper ends with deeper expressions (12, 13, 14, 15), which have a greater embossing depth and which lie together with their outer surfaces.
- These imprints (12 to 15) have through holes, so that these embossments (12 to 15) with the help of the through holes collecting channels form for the heat exchange medium.
- corrugated ribs (16) which are also preferably made of a an aluminum alloy sheet formed become.
- the heat exchanger corresponds to that of the State of the art construction, so that with respect to other Details can be referred to the prior art.
- the plate (11) located at the outer end is with a flat cover plate (17) covered.
- This cover plate (17) closes the embossments (13, 14) surrounded by flat surfaces.
- On the cover plate (17) is followed by a side part (18), which also is formed from a sheet of an aluminum alloy.
- the side part (18) has a substantially U-shaped shape and corresponds in width to the width of the plates (10, 11) and the cover plate (17). It relies on a lower one Flange (19) and an upper flange (20) on the cover plate (17).
- the lower flange (19) can be omitted, since the support by means of the corrugated fin (26) is sufficient.
- the side part is provided with an embossed profile (21).
- the embossed profile (21) has an edge on three sides surrounded, namely with the flange (20) and the edges (22, 23), with which it rests on the cover plate (17).
- the embossed profile (21) is open on the front side and forms thus with the cover plate (17) a connection opening (24) for a connector of a supply or discharge.
- the embossing (21) and the cover plate (17) formed chamber with the connection opening (24) stands with that formed by the embossments (12, 13) Collecting channel through an opening (25) of the cover plate (17) in connection. This chamber can thus be easily can be used as a connection for this collecting channel.
- the opposite end of the heat exchanger is corresponding Way on the then last plate (10) with a cover plate and provided a side part, which is also one of the Profiling (21) has corresponding profiling, while the cover plate is then provided with an opening which vcn the embossing channel (14, 15) formed with this Chamber connects. If in the chamber between the cover plate (17) and the side part (18) partitions can be installed other flow profiles can also be provided.
- the construction according to the invention has the advantage that a connection or at least one connection opening (24) in the from the plates (10, 11), the corrugated ribs (16), the cover plate (17) and the side part (18) and between the cover plate (17) and the side part (18) located corrugated fin (26) Block that is integrated in this way with a suitable clamping device is held.
- the educated one Block is then soldered in an oven. This will be more appropriate Way provided that the plates (10, 11), the cover plate (17) and the side part (18) and the opposite Elements are solder-plated, as well as the corrugated ribs if necessary (16, 26).
- the side part (28) of the embodiment according to FIG. 2 differs differ from the side part (18) only by the cross-sectional shape the embossed profile (31), which is a semi-cylindrical shape having.
- This profiling (31) is also sufficient one side to the edge of the side panel while on the other side is closed.
- the embossing (21, 31) of the side parts (18, 28) is open to both edges of the side part (18, 28).
- the "embossed" profile (21, 31) also by appropriate folding or folding of the side part achieve.
- profiling can have connectors on both sides record, i.e. Connection openings for connecting pieces form.
- the profiling becomes transverse dividing partition provided.
- This partition can be used as an insert can be carried out or as an undeformed Area between the two embossed profiles.
- This training has the advantage that identical Side parts (18) or (28) for both ends of the heat exchanger can be used, even if the supply and discharge to be connected on the same side.
- the side part (38) provided with an embossed, cup-shaped profile (41), which is surrounded by surrounding edges.
- embossed in one or both end walls Profile (41) a connection opening (34) for a connector a supply or discharge provided. Because this connection opening (34) formed exclusively by the profile (41) their shape can largely be chosen arbitrarily, regardless of the end plate (17).
- the side part with a embossed profiling (51) closed on all sides, the one with a cover plate (17), not shown outside closed chamber forms. Are then in the cover plate openings provided according to the collecting channels, so can this profile as a deflection guide for the refrigerant be exploited.
