Definitions
- the invention relates to a soldered refrigerant condenser, which consist of a heat exchanger network with flat tubes and corrugated fins, from collecting tubes which are in fluid communication with the flat tubes, and from a collector arranged in parallel to one of the collecting tubes and comprising a dryer and / or a filter takes up and is in fluid connection with the collecting pipe via two overflow openings - such a condenser is known from the applicant's EP 0 669 506 A1.
- This known condenser is a so-called condenser module, in which a collector is arranged parallel to one of the collecting pipes and is in fluid communication with the collecting pipe via two overflow openings.
- the refrigerant can pass from the collecting pipe into the collector, where there is a dryer, ie a container, usually made of plastic, which is filled with a dryer granulate for dehydrating the refrigerant.
- a dryer ie a container, usually made of plastic, which is filled with a dryer granulate for dehydrating the refrigerant.
- the strainer has the task, the refrigerant! clean of impurities in the form of the finest particles.
- the refrigerant then re-enters the condenser header pipe through the lower overflow opening.
- the section of the collector which forms the dryer and receives the dryer means is closed off at the top and bottom by a perforated plate. This means that the refrigerant can be accessed from both sides or the refrigerant can pass through the dryer area in both directions.
- a layer of felt is arranged between the lower perforated plate and the drying agent (granulate) - this prevents greater abrasion of the granulate and prevents any abrasion of the granulate.
- the granules are pressed together via a spring-loaded pressure plate, which also prevents abrasion by shaking movements.
- the end plates can be connected to the inner wall of the collector in a friction-locking, positive-locking or material-locking manner - this allows a firm connection either before or during the soldering process.
- the collector is in the
- Section between the end plates expanded in cross-section ie it forms in relation to the adjacent collector areas a paragraph in which the end plates can be positively or frictionally positioned and attached.
- a larger amount of granules can be taken up or the height of the dryer section can be reduced by this cross-sectional expansion - this increases the efficiency of the drying process.
- the upper end plate is formed by the closure of the collector, i. H. the drying section is at the top of the collector. This further simplifies the dryer since there are no more parts and operations.
- the filter is located in the lower region of the collector between the overflow openings, ie. H. it is separated from the dryer.
- the refrigerant flowing through the upper overflow opening into the collector flows directly into the filter - without flowing through the dryer. This reduces the pressure drop of the refrigerant, which flows through the collector with its entire volume flow.
- the drying of the refrigerant is nevertheless guaranteed because the refrigerant in the collector, even in its vaporous phase, comes into sufficient contact with the dryer granulate.
- the filter screen can also be easily positioned and fixed in the collector before the soldering process, e.g. B. by press fit. In addition to the types of connection already mentioned, it is also possible to glue or solder both the filter insert and the end plates for the dryer section.
- FIG. 1 shows a collector / collector pipe unit
- 2 shows the unit according to FIG. 1 in an exploded view
- FIG. 3 shows a section through the collector with dryer and filter.
- collector 1 shows a collector 1, consisting of a pipe section 2 and an extruded section 3, as well as a header pipe 4 with passages 5 for flat pipes, not shown, of a refrigerant condenser.
- Collector 1 and manifold 4 form an integrated unit of a condenser module mentioned at the beginning.
- FIG. 2 shows the unit according to FIG. 1 in two representations: the upper part shows the unit according to FIG. 1 in the assembled state; the lower part shows the collector 1 and the manifold 4 as separate components, i. H. before assembling them.
- the tubular section 2 is inserted into the extruded section 3 and soldered to it.
- the extruded section 3 has two overflow openings 5, to which two passages 6 on the collecting tube 4 are assigned.
- the more precise structure and assembly of the collector 1 and the collecting tube 4 are described in more detail in the applicant's older patent application with the file number 101 54 891.
- FIG. 3 shows the design of a collector 10 according to the invention, the design of which corresponds to the collector 1 in connection with the collector pipe 4 according to FIGS. 1 and 2.
- the collector 10 is composed of a pipe section 11 of lesser wall thickness and an extruded pipe section 12 of greater wall thickness.
- the lower pipe section 12 has an upper overflow opening 13, ie an inflow opening and an under overflow opening 14, ie an outflow opening.
- the upper pipe section 11 is inserted into the lower pipe section 12 and connected to it in the region of the joint 15 by soldering.
- the two pipe sections 11 and 12 are each at their opposite ends Cap 16, 17, also sealed by soldering, pressure-tight.
- the pipe section 11 which is made from a welded pipe, has a section 18 which is enlarged in its cross section and to which sections 19 and 20 with the same, smaller cross section adjoin on both sides.
- Such cross-sectional expansion can be made by widening the tube 11, for. B. by hydroforming (hydroforming) or so-called hydroforming.
- This cross-sectional widening in the area of the section 18 results in paragraphs 21 and 22 in the course of the tube 11.
- perforated disks 23 and 24 are inserted into the interior of the tube section 18, ie disks with passage openings 25 and 26, which in Many are distributed over the entire cross section.
- a felt layer 27 is arranged above the lower perforated disk 23, above which there is a drying agent in the form of granules 28 in a tight packing. This dryer granulate 28 is resistant to high temperatures, ie it does not experience any impairments during the soldering process.
- a pressure plate 29 is arranged above the uppermost layer of the granules 28 and is supported on the lower surface of the perforated plate 24 by means of a compression spring 30. This ensures that the package of the granules 28 is pressed together, does not slip and thus no abrasion occurs.
- the two perforated disks 23, 24 are supported on the one hand with their edges in the area of the transitions 21, 22 in a form-fitting and frictional manner with respect to the wall of the pipe section 11. In addition, they are soldered to the tube piece 11 during the final soldering process, so that they form an inseparable connection with the tube 11. Alternatively, the perforated plates 23, 24 can also be glued to the pipe section 11.
- a filter screen 31 is arranged, which is cup-shaped and a bottom 32 and has an annular edge region 33. The latter is inserted in an annular groove 34 in the pipe section 12 and anchored there. The preassembly before the soldering is thus carried out by inserting the edge 33 into the groove 34, and the final solid material connection takes place during the final soldering process of the capacitor.
- the filter screen can also be designed in a ring shape.
- the drying takes place in such a way that refrigerant vapor and / or refrigerant liquid, which reach the upper region of the collector 10, come into contact with the dryer granules 28 there and are therefore dehumidified.
- a secondary flow of the refrigerant thus forms in the upper region of the collector 10, ie above the inflow opening 13, which initially leads to the dryer granules 28 and from there - dehumidified - flows back in the direction of the filter sieve 31. This ensures both functions, drying and filtering.
- the invention can also be implemented in other collector designs, e.g. B. in a continuous extruded collector profile.
