Definitions

  • the invention relates to a heat exchanger as a soldering or welded construction, which has narrow and broad sides having flat tubes and corrugated fins and collecting boxes, which are designed as two shell-like parts, wherein the two parts are assembled in a central longitudinal plane of the heat exchanger or in a plane parallel thereto.
  • This heat exchanger is from the EP 864 839B1 and known from other publications.
  • the known heat exchanger has no tube plates but expanded tube ends, which are joined together in a block. The end edge of each two-part header encloses the final flush block of pipe ends.
  • the known heat exchanger has the advantage that a little less material, for example. Aluminum sheet, could be used because - as mentioned - tube plates are not present.
  • the operating weight of the heat exchanger is thereby reduced only slightly, because the expansion of the pipe ends requires comparatively larger wall thicknesses of the flat tubes, whereby the mentioned savings are partially reversed.
  • a not insignificant overhead is generated because of the implementation of the forming process at each pipe end.
  • the object of the invention is to provide a heat exchanger, which allows the use of flat tubes with thinner wall thicknesses, or which can at least mitigate the above-mentioned disadvantages.
  • the solution according to the invention results in the heat exchanger in that it is equipped with the features of claim 1. Because the two shell-like parts are provided with spaced-apart projections, which engage in the region of the narrow sides in the ends of the flat tubes, tubes with thinner wall thicknesses can be used because an expansion of the pipe ends does not have to be made. Furthermore, the advantage was achieved that the soldering critical joints are easily accessible, so they can be aftertreated if necessary. In a second soldering operation leaks can be eliminated.
  • the heat exchanger according to the invention has a pronounced advantageous relationship between its entire cross-sectional area to the effective heat exchange surface. It can therefore be used well the available space. It is envisaged that the ends of the flat tubes stuck in openings of pipe holders, the flat tubes have a supernatant on both sides of the tube sheets. In contrast to the openings in known tube sheets, the flat tube ends in the openings of the tube holder are not enclosed around the entire circumference of the opening edge.
  • the shell-like parts bear against the edges of the tube holder, wherein the projections engage in the region of the projections in the ends of the flat tubes, wherein they rest inside on the narrow sides of the flat tubes.
  • the one shell-like part is formed identical to the other shell-like part, wherein the connection of the two parts is arranged approximately in the central longitudinal plane of the heat exchanger. That on one of the shell-like parts a neck or the like should be formed and in so far as no identity of the parts could be present, is not taken into account here.
  • the one shell-like part is cup-shaped and the other shell-like part is approximately planar, wherein the connection of the two parts lies in a plane parallel to the central longitudinal plane.
  • essentially flat parts are also shell-like parts.
  • the central longitudinal plane or a plane parallel to it must not really be flat.
  • the term merely indicates an orientation extending transversely through the broad sides of the flat tubes.
  • the connection of the parts could, for example, be made along a corrugated configuration of the connecting edges of the parts It is envisaged that the shell - like parts have suitable means by which they are held together in a soldering or welding manner.
  • the means may be formed as arranged on the edge of the parts tabs and notches or the like, which engage in the assembly of the parts together
  • the means may in contrast be designed as formed on at least one of the parts, inwardly directed transformations, which are designed so that the parts can be connected, for example, put together in the sense of a prefixing together.
  • the inwardly directed transformations are, according to a further optional feature, designed to have flow-directing properties that promote the even distribution of the medium onto the flat tubes. It is further provided that the assembled shell-like parts have openings towards the end faces of the heat exchanger, with side parts or caps being provided which close the openings.
  • Fig. 1 shows a perspective view of a heat exchanger according to the invention.
  • FIG. 2 shows an enlarged detail from FIG. 1.
  • Fig. 3 shows this detail in an exploded view.
  • Figs. 4-7 show a modified embodiment in different views.
  • the heat exchanger In the heat exchanger, which is shown in the figures, it should be a cooled by means of cooling air charge air cooler for automotive applications, without wanting to exclude other heat exchangers and their applications somehow. But, quite the contrary, other heat exchangers and their applications are expressly provided, however, have not been shown in the figures.
  • the heat exchanger has at a collecting box 3 an inlet opening 36 for charge air to be cooled and at the other collecting box 3 an outlet opening 35 for cooled charge air.
  • the cooling air flows in the sense of the block arrow through the not shown corrugated fins 2, which are arranged between the broad sides 12 of the flat tubes 1 .
  • the type of flow of the heat exchanger in connection with the present proposal is not of interest, but it serves only to explain the illustration in Fig. 1.
  • the flat tubes 1 are alternately assembled with the corrugated fins 2 into a stack.
  • pipe holder 4 are attached to both ends of the flat tubes 1 .
  • the tube holder 4 have openings 40 that extend into the edge 41 of the tube holder 4, whereby the tube holder 4 differ, inter alia, of the usual tube plates.
  • the openings 40 may, if necessary and in a known manner, be provided with a collar-like passage pointing towards the corrugated fins 2 in order to improve the soldering with the flat tube ends.
  • the flat tube ends do not have to protrude inwards to the collection box 3 out. (not clearly visible)
  • the attachment of the tube holder 4 can be carried out so that the tube holder 4 are pushed transversely to their longitudinal direction towards the ends of the flat tubes.
  • the flat tubes 1 have a dimensionally minor but functionally important supernatant 5 on the two longitudinal edges 41 of the tube holder 4.
  • the collecting boxes 3 are added to the tube holders 4 at both opposite ends of the flat tubes 1 .
  • the side parts 70 provided in this embodiment are attached, as can be seen from the figures.
  • the collecting boxes 3 consist of two shell-like parts 31 and 32, wherein the one shell-like part 31 has a clear "open" shell shape and the other shell-like part 32 is formed quite flat.
  • side parts 70 are provided, remain after joining the two shell-like parts 31, 32, two end-side openings 33 which are closed by means of caps 71, which are part of the side parts 70 . It could also be provided individual caps, and the side parts can also be omitted. (not shown)
  • the side members 70 have an expansion slot 72 that permits operational expansions and contractions caused by thermal cycling.
  • the parts 31 and 32 are provisionally connected around their perimeter to be joined by means of tabs 61 and notches 62 which constitute the means 6 for connection mentioned above.
  • the two shell-like parts 31, 32 are equipped with projections 30 arranged at intervals, which engage in the ends of the flat tubes 1 in the region of the narrow sides 11 .
  • the distances of the projections 30 correspond exactly to the distances of the flat tubes 1, so that the collecting boxes 3 are pushed in the longitudinal direction of the flat tubes 1 on the ends thereof can, with each projection 30 engages in a flat tube end, and precisely in the respective above-mentioned supernatant 5.
  • Fig. 2 in the area of four projections 30 and flat tubes 1 a section was drawn, which is why the seated in the flat tube ends projections 30 to see are. As can be seen in particular in FIG.
  • the projections 30 have been formed with a corresponding slightly conical shape, so that they can slide on the one hand more easily in the flat tube ends and on the other hand also tightly abut, so that good soldering results are achieved.
  • the inventor has even made the edges of the projections 30 quite sharp-edged, because it was found that existing length tolerances of the flat tubes 1 can compensate well by the sharp edges of the projections 30 cut into the tube wall of the slightly longer flat tubes 1 , resulting in the mentioned compensation of the tolerances leads.
  • the projections 30 keep the tube walls under tension, whereby the so-called "collapse" of the flat tubes 1 during the soldering process is prevented. The "collapse" can lead to faulty solder joints.
  • each flat tube end 1 there are two projections 30 , which nestle inside each other in the two narrow sides 11 , and lead to the mentioned tensile stress in the tube wall.
  • the heat exchanger is equipped with a holding device 80 , which can be attached, for example, to hooks 81 or the like, which are in the case shown on the part 32 .
  • the holding device 80 may also be made of plastic.
  • inwardly directed deformations 65 were formed, on the one hand known to improve the stability, which is why the parts 31, 32 can be formed quite thin-walled. On the other hand, it is intended to influence the flow distribution by means of these inward "bumps". As is known, the middle tubes of a heat exchanger often flow through better than those that lie on the edge. As a result, on the one hand causes an undesirable temperature gradient and on the other hand often not achieved the maximum possible cooling performance. These disadvantages should be met by a targeted geometry of the transformations 65 .
  • the deformations 65 may, as shown, be located on both parts 31, 32 or only on one of the parts. FIGS.
  • the parts 31, 32 or 65, 66, 67 should correspond, so that the purpose is achieved, which is to hold the parts 31, 32 and also to influence the flow, which in particular Figs. 4 and 5 illustrate, but this also in the first embodiment with the help of the local formations 65th happens.
