Definitions

  • the invention relates to a heat exchanger with a plurality of tubes, the Ends in around the openings in the tube sheets, pointing towards the heat exchanger network Insert passages, the cross section of which is curved inwards, and the are connected in a liquid-tight manner, through the pipes and around separate heat exchanging media flow around the pipes.
  • Heat exchangers equipped with these features are known from EP 798 531 known. Because the pressure loss of the heat-exchanging media is always low in this document, the passages are advantageously to the heat exchanger network been ordered. This ensures that the ends the pipes do not have to have an overhang that extends into the collecting space extends.
  • the cross section of the passages has an inward curvature, to facilitate the insertion of the pipe ends.
  • the disadvantage is that the ends The tubes need to be widened in a tulip-shaped manner due to the bulge to reduce the reduced connecting area with the swings again and to achieve a tight metallic connection by soldering.
  • the expansion requires an additional operation.
  • the individual tube ends are down to the level of the tube sheet level or even been inserted into the passages up to this level, whereby the individual pipes with the same size of the heat exchanger a little longer have to be what with a multitude of such pipes as additional weight and imposes additional costs.
  • the object of the invention is to further improve the stated state the technology regarding the metallic connection between the pipes and the tube sheets in a heat exchanger, which is the preamble of the claim 1 corresponds.
  • the pipe ends to below the Extend levels of the tube sheet surface and with the passages a circumferential Form the contact surface between the two sides in a soldering gap Pipe and thread runs out.
  • the pipe ends are preferably not widened or drawn in, although after the inventive teaching these variants are also possible.
  • soldering gaps on both sides cause the solder to adhere during the soldering process stuck in these soldering gaps and thus a perfect, tight solder connection arises.
  • the heat exchangers to be soldered no longer have to be in one be placed in the soldering oven such that the solder in the joints can flow.
  • the adhesive forces also hold the solder against gravity, i.e.
  • the location of the heat exchanger to be soldered is irrelevant, which means essential Simplifications of the manufacturing process are possible.
  • connection area is significantly smaller than in the prior art solder joints can be produced according to the teaching of the invention, which in each Relationship meet the requirements.
  • the tubes are preferably designed as flat tubes, the same positive ones Effects also occur with all other cross-sectional shapes of the pipes.
  • the pipe ends are preferably located around the thickness of the Tube sheet below the one tube sheet surface. So that is occurring Pressure drop is extremely low.
  • the opening angle of the also circumferential, acute-angled soldering gaps lies in Preferred range from 10 to 25 °, because it has been found that at this opening angle with a view to the adhesive forces to achieve the best results are.
  • the opening angle of the two soldering gaps can be different or equally large opening angles can be provided on both soldering gaps become.
  • the circumferential connection surface should have a width that is approximately in Thickness range of the tube sheets is or is larger, which is however significantly smaller than in EP 798 531.
  • Heat exchangers of the generic type can be referred to as mass products where there are already supposedly minor improvements or Differences from the known prior art lead to considerable advantages.
  • the heat exchanger consists of a plurality of tubes 1, the ends 2 in Openings 4 of the tube sheets 3 arranged and liquid-tight with the passages 5 are connected by soldering.
  • Figs Tube 1 shown because all tubes 1 of the heat exchanger in the same Are fixed in the openings 4 of the tube sheets 3.
  • the tubes 1 are Flat tubes.
  • the cooling network is usually below the tube sheet 3 consisting of the aforementioned plurality of tubes 1 and between the tubes 1 arranged slats or corrugated ribs, not shown. Through the corrugated ribs cooling air usually flows through and 1 cooling water or inside the pipes Air, for example charge air, which is to be cooled.
  • the pipe ends 2 are clearly below the tube sheet surface 6 has been arranged.
  • the distance between the tube ends 2 and the tube sheet surface 6 equal to the thickness d of the tube sheet 3.
  • the same dimension has the width b of the contact surface -or Connection surface 7.
  • the opening angle ⁇ is above and below 20 °. Only the lower opening angle ⁇ was drawn.
  • the tube sheet 3 and / or the tubes 1 are made of solder-coated aluminum been. But it could also be another solder coated, act metallic material.
  • solder layer melts and is forced into the soldering gaps by adhesive forces 8 drawn in or adheres to the soldering gaps 8. This will make the interface 7 slightly enlarged, because depending on how much solder is available, fill the soldering gaps 8 with the same and ensure a perfect, tight and durable solder joint.
  • FIG. 2 is a view from the long side of the flat tube 1.
  • the end 2 of the flat tube 1 has been slightly sculpted, but the upper and lower solder gap 8 with its described advantages is retained.
  • the tulip which does not require an additional operation, as far as network installation is concerned is carried out at the same time that the tube sheets are being pulled up
  • Advantages that the cohesion of the parts before soldering is improved and that the solder gap 8 is narrower, which further improves the adhesion effect. It will also depend on the degree of deformation of the passages 5, whether you choose this Embodiment decides, or the one from Fig. 1 chooses.
  • Fig. 3 shows the basic structure of an intercooler and only a part the same.
  • Flat tubes 1 and folded fins 9 form a heat exchanger network put together.
  • the hot charge air flows through the flat tubes 1, as by means Flow arrows has been indicated.
  • the cooling air flows freely through the Slats 9 occupied spaces.
  • the heat exchanger network is replaced by a Side panel 10 limits that usually at opposite ends as well is connected to the tube sheets 3.
  • the tube sheet 3 has on the peripheral edge a U-shaped deformation in which a seal 11 is located.
  • In this U-shaped Forming is a so-called air box 12 with its in the circumferential Forming appropriate edge termination used and by bending individual tabs of the U-shaped forming attached sealing.
  • the hot one Charge air enters the air box 12 through the charge air inlet 13 and is distributed on the flat tubes 1. Because the flat tubes 1 are slightly below the level of the Tube bottom 3 ends, the pressure loss of the charge air remains very low.
