Definitions
- the invention relates to a double tube heat exchanger from two coaxially nested tubes, in particular Made of aluminum that form together at their ends of a flow channel lying between them is tightly connected are, where appropriate in the flow channel Turbulence insert is used, as well as a method for its Manufacturing
- Double tube heat exchangers of this type are known. So shows For example, DE-OS 30 21 240 one made of stainless Steel existing double tube heat exchanger, in which the two Steel pipes at their ends using a fusion welding process are interconnected. For this purpose is there the inner tube expanded in its end area, and so far that the expanded part of the inner tube over a certain Length runs parallel to the outer tube. In this area the welding is done. Between the two pipes sits a turbulence insert.
- this double tube heat exchanger In the manufacture of this double tube heat exchanger the procedure is such that after the Attach to fittings on the outer tube using a Hump welding process the two tubes with the help of a device are pushed into each other at a distance, then the ends of the inner tube by applying pressure like that be widely expanded that they on the outer tube for the purpose of Apply welding.
- Such a method of manufacture is proportionate complex.
- From DE-OS 26 12 416 is a similarly constructed double tube heat exchanger known in which also the ends of the Inner tube bent outwards for the purpose of welding until they are in contact with the outer tube.
- the invention has for its object a double tube heat exchanger of the type mentioned and a procedure to propose its manufacture, in particular for the Use of aluminum as a starting material are suitable make a complex assembly process unnecessary and also avoid the risk of corrosion.
- a double-tube heat exchanger is used to solve part of this task of the type mentioned at the beginning at least one of at least on both ends of the tubes one of the tubes protruding circumferential beaded collar provided is whose height is the difference in the radii of the inner wall corresponds to the outer and the outer wall of the inner tube and where the bundle is tightly soldered to the pipe wall they are concerned with. Need through this design the two tubes are only pushed axially one above the other the necessary annulus is already involved in this process forms between the tubes. A separate alignment is not necessary because the bundles take over this alignment.
- the bundles also serve for tight soldering, whereby according to the invention provided and explained later
- Nocolok soldering process is expedient (see SAE Technical Paper Series, Claydon and Sugihara, Brazing Aluminum Automotive Heat Exchanger Assemblies Using a Non-Corrosive Flux Process, International Congress & Exposition Detroit USA, February 28 to March 4, 1983) is used using a flux that according to soldering is not corrosive and therefore its residues also do not need to be removed. It is necessary that at least one of the pipes to be merged later from a suitable one there is solder-plated material and to the soldered Places with Nocolok flux. It can either both pipes or only one plated accordingly become. It is also possible to close the turbulence insert plate.
- each bead-like collar can from the material of the pipe shortly before its end in Art a surrounding bead. It is possible making sure that each tube has a bead at only one end is, the beads then when inserting the Pipes face each other and the flow channel between them lock in. But it is also possible, only one Pipe with two beads and the other pipe smooth allow. Rolling to form the beads is also possible.
- the new double tube heat exchanger is particularly suitable as Oil cooler for installation in a water box of a cooler for an automobile engine.
- a double-tube heat exchanger designed as a double-tube oil cooler, which consists of an outer tube (1) and an inner tube (2) each made of solder-plated aluminum.
- the tubes are made from a flat material bent after plating to form a tube and joined with a longitudinal weld.
- Two connecting pieces (3 and 4) are placed on the outer tube in a manner known per se, through which oil, for example hot engine or transmission oil, in the direction of the arrows (5) into an annular flow channel (6) between the outer tube and the inner tube (1 or 2) can be performed, which is to be cooled by a second heat exchange medium, in the exemplary embodiment water, which is guided through the inner tube (2) and enters it in the direction of the arrow (7).
- the oil flows through the inlet connection (3) and through an inlet opening (not shown) in the pipe (1) and leaves this flow channel through the outlet connection (4) and through one also not shown opening in the outer tube (1).
- the flow channel (6) is provided with a turbulence insert (8) which is designed in a known manner.
- the flow channel (6) is delimited on the outside by a circumferential bead-like collar (9) which is pressed out in the form of a circumferential sikke (see also FIG. 2) from the inner tube (2) in the region of the left end (2a) thereof.
- the height (h) (Fig.
- the double tube oil cooler of FIG. 1 proceeded so that first the inner tube (2) in the area both ends with the beads pressed out Collars (9 or 10) is provided. The inner tube (2) or that The outer tube (1) is then provided with flux and after arranging the turbulence insert (8) between the collars (9 and 10) the outer tube (1) is pushed on axially. It will then generally an expansion of the inner tube (2) is also provided to the turbulence plate (8) in the annular Flow channel (6) in a solderable system on the pipe walls bring to. Then the arrangement so made heated to the necessary temperature in the soldering furnace so that tight solder joints in the area of the bundles (9 and 10) and of course also in the area of the attached connecting piece (3 and 4) arise. After cooling, the double tube heat exchanger is finished.
- Fig. 4 shows a variant in that here a smooth Outer tube (1) (as in Fig. 1) is provided, however, that Inner tube (2 ') rolled outward at its left end Bund (11) has dimensions of that of the federal government (9) correspond. Also through this rolled collar (11) becomes a system and guidance of the outer tube (1) during assembly reached. At the same time, this collar (11) serves as a sealing point after the soldering process. Also in this embodiment can the inner tube (2 ') at both ends with a outside rolled collar (11). It is also possible the arrangement of only the left rolled covenant shown (11) while the outer tube (1) rolled one inward Has collar on the right side, so that an assembly like in Fig. 3 is possible.
- the outer tube (2) rolled inwards Bunde has, like that in principle also with the 1 possible in the technical reversal where the bundles (9 and 10) are not from the inner tube outwards, but inwards from the outer tube (1) are.
- All embodiments ensure easy assembly and are particularly suitable for the manufacture of double tube heat exchangers made of aluminum and for soldering using the no-colok process.
- 5 and 6 is an advantageous embodiment of the new double tube heat exchanger shown in that the double tube heat exchanger there as an oil cooler directly into one the cooler header boxes for the engine coolant are installed.
- a double-tube cooler (12) for this purpose.
- a collecting box (13) not shown - because known - coolant cooler installed for a motor vehicle engine.
- the collecting box (13) is known from its lower end (13a) completed by a tube sheet, not shown, and it therefore takes place along the axes (14) in the tube sheet opening, but also not shown pipes, an inflow of the outer tube (1) of the double tube oil cooler (12) instead.
- the flow of the coolant also penetrates - if suitable Arrangement of the double tube cooler for the inlet or return nozzle the collecting box (13 - the interior of the inner tube (2).
- the outer tube (1) Provide an opening (15) in at least two places and then you have the edge of this hole with usual Middle pulled out like a collar and in the form of the beaded edge (16) flanged around an opening in the collecting box (13).
- a connecting piece (3 ') has then been placed, the same as the flanged edge (16) with the collecting box (13) is soldered tight.
- the collecting box in the exemplary embodiment (13) also made of a solder-plated aluminum, so that it is sufficient for the production, the appropriate flux in the area of the edge (16) and in the area of the seated Bake the connector (3 ') to apply using the Nocolok process a complete tight soldering of the double tube cooler (12) (as also explained in the previous figures is) and the connection between this double tube cooler and the collecting box (13) and its connecting piece (3 ').
- the outer tube (1) is of course except the Opening (15) with the connecting piece (3 ') also another, Assigned in Fig. 5 opening, not shown, which in attached to the collecting box (13) in the same way and with this is soldered so that, as in the examples of FIG. 1 to 4, through the connecting piece (3 ') the oil to be cooled in the space between the outer tube (1) and inner tube (2) supplied and again through the connection piece, not shown can be dissipated.
- the advantage of the embodiment shown in FIG. 5 is that a cooler made entirely of aluminum with can be made available to a double tube oil cooler, on which no other materials are used, so that a easy recycling is possible.
- FIG. 6 shows an embodiment largely similar to that of Fig. 5. The only difference is that here the of the Opening (15) from the outwardly drawn neck (17) of the double tube cooler (12 ') not around the edge of a corresponding opening flanged around in the collecting box (13 '), but in one corresponding recess (18) of the connecting piece (3 '') pressed in is.
