Definitions
- the invention relates to a soldered heat exchanger network according to the preamble of claim 1.
- Heat exchanger e.g. B. coolant cooler or refrigerant condensers for motor vehicles have a heat exchanger network, which consists of tubes and fins, the tubes z. B. flows through of coolant or refrigerant and the fins of cooling air, in particular ambient air overflow.
- the tubes are designed as flat tubes and the fins as corrugated fins, which are soldered to the flat longitudinal sides of the flat tubes with their corrugated ridges.
- Flat tubes with greater depth, d. H. measured in the direction of the air flow are often designed as so-called multi-chamber tubes, d. H.
- Such heat exchanger networks are manufactured in such a way that flat tubes and corrugated fins are cut to length and then “cassetteed” in a suitable device, that is to say corrugated fins are arranged next to the flat tube and joined to form a block, which is then braced and placed in a soldering furnace (optionally with the associated tube sheets or
- a modified tube shape also shows two beads (webs) folded from the tube material, which are soldered to the opposite side of the tube and form a total of four chambers.
- Folded multi-chamber flat tubes are known from EP-A 457 470, in which folded webs are alternately formed from opposite tube sides and in each case soldered to an opposite inner tube wall.
- multi-chamber tubes with opposing folded webs are known, which only extend to the middle of the clear tube width and are soldered together there.
- the multi-chamber tubes can be formed in one piece, ie provided with a welded longitudinal seam or also in two parts, ie with folded and soldered longitudinal seams arranged on the narrow sides.
- Another form of a folded multi-chamber flat tube has become known from the applicant's DE-A 102 12 300, in which a manufacturing method is also described.
- corrugated fins are arranged between the flat tubes and have gills or gill fields to improve the heat transfer.
- Such gill fields such as. b. EP-B 547 309 shows being arranged continuously in the air flow direction or - as shown in US-A 4,693,307 - in individual gill fields, between which smooth, i. H. uncombed corrugated fin areas.
- the object of the present invention is therefore to improve a brazed heat exchanger network of the type mentioned at the outset by suitable measures such that perfect brazing takes place both on the outside and on the inside of the multi-chamber flat tubes.
- the corrugated ribs are smooth in the area of the webs, i. H. are not gilled.
- In the area of the webs means: in the extension of the webs across the flat sides of the multi-chamber flat tube.
- Gills or gill fields are arranged in the areas between the webs, so that gill fields are assigned to the chambers of the multi-chamber flat tube at approximately the same depth.
- a "keeled" corrugated fin does not have a uniform fin height, but that in the areas of the individual gill fields there is a lower fin height, the minimum height, than in the smooth, ie ungilled areas, where a greater fin height, the maximum height, occurs
- This unevenness in the height of the ribs can be attributed to the fact that by cutting and then “unscrewing” the gills, the corrugated fin is “drawn in” in the area of the gills, ie “waist”.
- the inventors took advantage of this knowledge and adapted the corrugated fin with its gill arrangement to the multi-chamber flat tubes.
- the multi-chamber flat tubes have longitudinal seams which are either soldered or welded and are preferably arranged on one or both narrow sides of the multi-chamber flat tube. This avoids asymmetries on the flat sides of the tubes that could affect the soldering process.
- the corrugated ribs also have smooth areas on the inflow and outflow sides. In particular, straight leading and trailing edges and a laminar start-up section for the air flow are achieved.
- the smooth areas of the corrugated fin each have the same and maximum fin height. This ensures that the same contact pressure is exerted on all webs and that the solder gaps between the web back and the inner pipe wall are evenly minimized. Uniform soldering with sufficient strength for a tie rod effect is thus achieved.
- the areas covered with gills have a minimal rib height. This means that the tensioning force when tensioning the net does not act as a surface load on the shaft crests, but rather directly on the webs in a punctiform manner, thereby compressing the flat tubes in the area of the webs up to the stop.
- the multi-chamber tube has two identical chambers, which are separated by a central web, in the area of which the corrugated fin is smooth.
- This is the simplest form of the multi-chamber pipe, which is used for relatively small system depths.
- the number of chambers or webs can be increased as desired, two webs with three chambers being a preferred solution for motor vehicle heat exchangers.
- the corrugated fin of FIG. 1 in a side view Fig. 2 is a multi-chamber tube with lateral corrugated fins.
- Fig. 1 shows a corrugated fin 1 in a view from above
- Fig. 1a shows the corrugated fin 1 in a side view.
- the corrugated fin 1 serves as a secondary heat exchange surface in air-cooled flat tube systems or heat exchanger networks.
- the air ambient air
- the rib height corresponds to the amplitude of the corrugation (cf. FIG. 1a) and is marked with H.
- the corrugated fin 1 is preferably made of a thin aluminum sheet, into which gills 2 are cut to improve the heat transfer on the air side, which are arranged in the form of gill panels 3, 4 on the fin surface.
- the gills 2 are - which is not shown here, but emerges from the aforementioned prior art (EP-B 547 309 or US-A 4,693,307) - inclined to the rib surface and form a so-called gill angle.
- the incision and the subsequent twisting of the rib material results in a constriction in the area of the gill panels 3, 4, which are represented by dashed lines 5.
- These constrictions lead to a reduction in the rib height H.
- the reduced rib height is marked with h and represents the minimum rib height.
- the maximum rib height is marked with H and occurs outside the gill fields 3, 4, i. H.
- the corrugated fin 1 has corrugated ridges 1a, 1b with which the corrugated fin 1 rests on the pipes, not shown here. Because of the constrictions 5, the wave crests 1a, 1b thus do not form a continuous straight line. The gills 2 protrude into the air flow.
- FIG. 2 shows a folded multi-chamber tube 6 which has two flat longitudinal sides 6a, 6b and two rounded narrow sides 6c, 6d. From the above Ren long side 6a, two webs 7, 8 are formed by folding, which are soldered to the opposite long side 6b and thus form tie rods.
- the multi-chamber tube 6 is made of a sheet metal, which is closed on the narrow side 6d by a welded longitudinal seam 9.
- the multi-chamber tube 6 thus has three chambers 10, 11, 12, in which a coolant or refrigerant flows. Outside the multi-chamber tube 6, corrugated fins 13, 14 are arranged on the longitudinal sides 6a, 6b thereof, which are soldered to the multi-chamber tube 6.
- Corrugated fins 13, 14 and multi-chamber tube 6 thus represent a section of a heat exchanger network, not shown, which is constructed according to this pattern and can be used in coolant coolers or refrigerant condensers for motor vehicles.
- the corrugated ribs 13, 14 each have three gill arrays 15a, 15b, 15c and 16a, 16b, 16c, between which non-keeled, ie smooth areas 17a, 17b and 18a, 18b are left.
- the arrangement of the gill panels 15a, 15b, 15c, 16a, 16b, 16c is selected such that they are located in the area of the chambers 10, 11, 12 and the smooth areas 17a, 17b and 18a, 18b in the area of the webs 7, 8 are arranged.
- these corrugated ribs also have reduced rib heights h due to the gill panels 15a to c and 16as to c and maximum rib heights H in the smooth regions 17a, 17b, 18a, 18b. Due to the selected arrangement, the maximum fin heights H, seen in the depth direction, are at the level of the webs 7, 8 and on the inflow and outflow sides of the corrugated fins 13, 14. As explained at the beginning, corrugated fins 13, 14 and multi-chamber tubes 6 are cassetted to form a heat exchanger network and then - to prepare for the soldering process - clamped using suitable clamping devices.
