Definitions
- the invention relates to an adhesive connection for heat exchangers, in particular an adhesive connection of metallic flat tube ends, which are part of a brazed heat exchanger network, into corresponding openings of a collecting tank made of plastic, each with an annular space around the pipe ends, wherein a silicone adhesive in the Annular spaces is located. Furthermore, the invention relates to a manufacturing method for the adhesive bond of the heat exchanger and for the heat exchanger itself.
- WO 2006 / 010435A1 likewise uses a silicone-based adhesive to produce a heat exchanger for motor vehicles. It is an initially liquid mass, which is poured out there on the inside of a tube plate and then cured. An annular space around the pipe ends is not there. The pipe ends have been deformed, in particular widened, which causes manufacturing expense. Here, a large amount of the adhesive is needed, which also increases the cost of production.
- WO 2007 / 009588A1 an automotive radiator is presented, which also has deformed pipe ends and has no annular spaces. The pipe ends were not glued there but fixed by bending the pipe ends. This car radiator also has a separate metallic tubesheet, which is to be regarded as disadvantageous.
- Silicone adhesives are either of the so-called condensation-curing type (A) or of addition-curing type (B).
- the silicone adhesives of the condensation-curing type (A) excrete certain substances, for example acids or alcohols, when they cure, while those of the addition-crosslinking type (B) in the course of their curing lead to the formation of molecular chains without precipitating substances.
- the type B adhesives may comprise a catalyst, for example platinum or palladium.
- Such catalysts are usually in one of, for example, two components which must be mixed to prepare the ready-to-use adhesive.
- the catalysts cause, for example, a shortening of the curing time, and they can also help reduce the required temperature.
- the object of the invention is to propose or make available a permanently durable adhesive bond for heat exchangers and a production method therefor. This object is achieved by an adhesive bond having all the features of claim 1.
- the fatigue strength of the adhesive bond is improved by virtue of the silicone adhesive being of the addition-crosslinking type, with a mounting plate being provided which delimits the annular spaces.
- the elastic modulus or storage modulus of the silicone adhesive is relatively low in order to minimize the forces of changes in length induced by temperature changes and the vibrations in the adhesive bond. It is preferably between about 0.1 and 3.0 MPa.
- the mounting plate is adhesively attached with its top on the collecting box. It can lie with its underside on the fins of the heat exchanger network.
- annular spaces are filled to about 60-95% with the silicone adhesive, wherein the filled with the silicone adhesive height of the annular spaces about 5 - 15 mm and the width of the annular spaces about 0.5 - 3.0 mm .
- the filling of the annular spaces with the adhesive to about 60-95% of its volume, together with the specified preferred dimensions of the annular spaces, increases the elasticity of the adhesive bond, which is confirmed by numerous series of experiments carried out by the Applicant. A not inconsiderable number of coolers with adhesive bonds formed in this way will soon be tested in practice, that is, installed in motor vehicles in use on public roads. So far, all the coolers tested in the test laboratory and in the field of internal use have met expectations.
- the dimensioning of the annular spaces it has been found that this also depends on the length of the flat tubes provided in the individual case and on the dimensioning of the cross section of the flat tubes.
- the width and height of the annular spaces may be at the upper limits.
- flat tubes of cooling liquid coolers which are only about 1, 0 - 1, 5 mm thick (d) are more suitable at the lower limit width dimensions.
- slightly longer flat tubes for example, up to or over 1.0 m, as they are found in trucks, you would also rather provide a slightly wider and higher filled annulus, because then expected by temperature changes length changes of the flat tubes by means of the elasticity of the adhesive joints better to compensate.
- an initially approximately rectangular cross-sectional area of the adhesive in the annular space under the mentioned thermal cycling loads in the direction of a parallelogram cross-sectional area - and back to the rectangular shape - move, which is ensured by the elastic properties of the selected adhesive together with the proposed design.
- a two-component silicone adhesive is used. But it can also be a silicone adhesive with a single component.
- the tensile strength of the silicone adhesive used is about 3.0 to 7.0 MPa, preferably about 4.0 to 6.0 MPa.
- the elongation of the silicone adhesive used is greater than 100%, for example, it is 150%.
- the silicone adhesive used has a catalyst from the group of platinum metals or their compounds.
- the dynamic viscosity of the uncured silicone adhesive is about 20,000 - 60,000 cP.
- the adhesive can be applied to the mounting plate like a worm without flowing apart.
- the annular spaces can have approximately the same width over the filled with the silicone adhesive height.
- the specified width dimensions refer to conical annular spaces on the median, that is, the specified width dimensions can be slightly exceeded in conical annular spaces.
- the not filled with the silicone adhesive part of the annular spaces should be arranged pointing to the collection box.
- the inventive method for producing an adhesive connection for metallic flat tube ends in corresponding openings of headers of a heat exchanger in which a silicone adhesive is introduced into an annular space between the flat tube ends and the openings is characterized in that the annular spaces with a low memory module possessing silicone adhesive from addition-curing type filled and sealed by means of a mounting plate.
- An inventive production method for heat exchangers has the features of claim 33.
- the mounting plate has openings corresponding to the flat tubes in order to be able to push the same onto the flat tube ends, so that, for example, it lies with the underside on cooling-air-side ribs.
- the opening edges of the mounting plate are close to the flat tube ends to avoid the escape of the adhesive as possible.
- the silicone adhesive is preferably applied to the top of the mounting plate and pressed by the subsequent merger of mounting plate with the collecting box, wherein the flat tube ends are pushed into the openings of the collecting tank, in the annular spaces.
- the flat tube ends are pretreated as needed, at least cleaned with a suitable means to z. B. to remove solder flux, which have been found to be detrimental to a quality adhesive bond.
- the flat tube ends are part of a heat exchanger network of flat tubes and cooling air-side ribs connected by means of CAB brazing processes, both of aluminum or of aluminum alloys.
- This method of soldering normally uses a non-corrosive flux, although intensive work is being done to completely eliminate flux. In any case, surface treatments may be required and performed on both the flat tube ends and the aperture walls.
- the mounting plate has openings corresponding to the flat tubes in order to be able to push the same onto the flat tube ends, so that, for example, it lies with the underside on cooling-air-side ribs.
- the opening edges of the mounting plate are yieldingly close to the flat tube ends in order to be able to compensate for differences between the distances between the openings in the mounting plate and the spacings of the flat tube ends.
- the distances between the openings can be changed or adapted by means of an elastic or resilient design of the mounting plate. This also ensures that neither the flat tube ends nor the mounting plate are damaged and that no adhesive loss occurs due to too large gaps between the flat tube ends and the opening edges of the mounting plate.

- Fig. 15 shows the cross section of a second embodiment as an alternative to Fig. 14; Fig. 16 - 18 production process and front view of a heat exchanger; Numerous practical experiments and simulation calculations have shown that the preferred width b of the annular space 6 or the adhesive joint 1 is between 1.5 and 2.5 mm and the preferred height h of the annular space 6 filled with the silicone adhesive SK or of the adhesive joint 1 is approximately between 5, 0 - 10, 0 mm can be found. This should be clarified by the Fig. 1. The width b and the height h were drawn in FIG. 4. From the mentioned Fig. 4 also shows that the upper part 60 of the annular space 6 is not filled with the silicone adhesive SK.
- the silicone adhesive SK used is of the addition-curing type, ie it does not precipitate any substances when it is cured.
- the storage modulus of the silicone adhesive SK in the exemplary embodiment is about 1.8 MPa, selected from a range between 0.5 and 3.0 MPa. This relatively low value contributes significantly to the durability of the adhesive bond, wherein the adhesive compound has excellent elastic properties and retains over a long period of time.
- Flat tubes 20, as shown in Fig. 5, are alternately assembled with fins 30 to the heat exchanger network 3.
- the heat exchanger network 3 becomes the CAB Soldering prepared accordingly, the soldering process is carried out.
- the free flat tube ends 2 are optionally freed of residues of the flux or other interfering residues or their surface is treated.
- a mounting plate 10, a thin film of about 1, 0 mm thickness or less, as shown in Figs. 2 and 3, is pushed with its openings 12 on the flat tube ends 2, wherein the opening edges abut quite narrowly against the flat tube walls.
- the mounting plate 10 can sit with its bottom finally on the ribs 30 without being attached thereto. In contrast, in FIG. 4, a small distance between the underside of the mounting plate 10 and the ribs 30 can be seen.
- a metered amount of the silicone adhesive SK as shown in Fig. 6, a serpentine on the inside of the mounting plate 10 is applied.
- the collecting box 5 is pushed with its openings 4 on the free flat tube ends 2.
- the collecting box 5 comes together with the shell-like mounting plate 10, that is, the wave-like edge 11 of the mounting plate 10 engages in a correspondingly shaped, circumferential groove 50 in the collecting box 5 a.
- the top of the mounting plate 10 glued to the bottom of the manifold 5.
- the collecting box 5 is integrally formed.
- An embodiment not shown has a tube sheet of metal or plastic, in which the openings 4 are located, which is later connected to a box part along the peripheral edges to form the collecting box 5.
- shell-like mounting plate 10 with collecting box 5 especially the silicone adhesive SK is pressed into the annular spaces 6.
- edge 11 in the circumferential groove 50 prevents the merging of collection box 5 with mounting plate 5 of the silicone adhesive SK can escape laterally. He is rather forced to enter the annular spaces 6.
- the height H of the edge 11 has therefore been designed so that it already engages in the groove 50 before the impressions of the silicone adhesive SK begins in the annular spaces 6. The state shown in Fig. 4 is thus achieved.
- the degree of filling of the annular spaces 6 in this embodiment is about 75%, that is, 25% of the volume of the annular spaces 6 are not filled with the silicone adhesive SK.
- the parts of Openings 4 in the collecting box 5 are to avoid that the silicone adhesive SK comes later in substantial contact with the medium flowing through the heat exchanger.
- FIG. 4 For illustration in Fig. 4 should also be noted that the flat tube ends 2 practically do not protrude into the interior of the collecting tank 5, even if the Fig. 4 could convey a different impression. Namely, in its opening or bottom area, the collecting box 5 has a roughly semicircular contour, viewed in cross-section, in order to improve its pressure stability, so that FIG. 4 could give the impression that the flat tube ends 2 are clearly inwardly over, which is actually the case only applies to the lying on the central longitudinal line lot of the flat tube ends 2. The internal pressure loss has therefore been reduced.
- the total cross section of the header tank 5 is round to oval, which is to show the Fig. 7.
- the mounting plate 10, one of the flat tubes 20 and a part of an annular space 6 were indicated there only in stylizing manner.
- the tensile strength of the silicone adhesive SK in the embodiment is about 5.3 MPa, selected from an advantageous range of between 3.0 and 7.0 MPa.
- the viscosity of the silicone adhesive SK is about 35,000 cP, selected from a range between 20,000 and 60,000 cP. With this value, the silicone adhesive SK can be applied without flowing apart.

- the heat exchangers are maintained at a temperature of about 120 0 C for about 30 minutes, selected from a temperature range of 80-180 0 C and a time between 1-60 minutes.
- the silicone adhesive SK was mixed with a catalyst from the group of platinum metals in order to shorten the curing time.
- the thickness of the wall parts a, b (Fig. 5) of the flat tubes 20 is extremely small, namely in a range of 0.03 mm - 0.15 mm, because the ribs 30 only about 0.03 mm - 0.09 mm thick and because, moreover, preferably no metallic tube sheet is used, a much lighter heat exchanger is provided. Its performance characteristics are also significantly higher than for ordinary heat exchangers, partly because of the inner inserts c in the flat tubes 20. Moreover, such heat exchangers require considerably less energy, for example for the soldering process. In the provision Such a heat exchanger makes the proposed invention a significant contribution.
- the procedure is as follows: Flat tubes 20 are alternately assembled with ribs 30 to the heat exchanger network 3.
- the heat exchange network 3 is prepared according to CAB soldering, the soldering process is carried out.
- the free flat tube ends 2 are optionally freed of residues of the flux or other interfering residues or their surface is treated.

- the opening edges 13 may be formed with cuts 14 and / or tapered 15, as shown in Figs. 8 - 10 is shown.
- a second embodiment of the opening edges 13 is shown in Fig. 12, wherein the compliance is represented by a locally reduced material thickness in the form of a shoulder 16.
- the locally reduced material thickness is realized by means of grooves 17 or beads, as shown in Fig. 13, wherein the shape of the grooves or beads need not be limited to a circular arc-shaped depression in cross-section.
- FIGS. 14 and 15 the resilient configuration of the distances of the openings 12 in the mounting plate 10 by reducing the material thickness in the edge regions between the openings 12 and the wave-like edges 11 of the mounting plate 10, (FIG. 14), or between the openings 12 across the mounting plate 10, ( Figure 15).
- the mounting plate 10 can sit with its bottom finally on the ribs 30 without being attached thereto. In contrast, in FIG. 4, a small distance between the underside of the mounting plate 10 and the ribs 30 can be seen. Subsequently, a metered amount of the silicone adhesive SK, a serpentine on the inside of the mounting plate 10 is applied (not shown). Thereafter, the collection box 5 is pushed with its holes 4 on the free flat tube ends 2. In this case, the collecting box 5 comes together with the shell-like mounting plate 10, that is, the wave-like edge 11 of the mounting plate 10 engages in a correspondingly shaped, circumferential groove 50 in the collecting box 5 a.
- the top of the mounting plate 10 glued to the bottom of the header tank 5.
- By merging the shell-like mounting plate 10 with the collecting box 5 of the silicone adhesive SK is pressed into the annular spaces 6.
- By the mentioned intervention of the edge 11 in the circumferential groove 50 prevents the merging of the collecting box 5 with the mounting plate 10 of the silicone adhesive SK can escape laterally. He is rather forced to enter the annular spaces 6.
- FIG. 18 a cooling liquid cooler (heat exchanger) of a truck is shown, the heat exchanger network is flowed through by cooling air.
