Definitions

  • the invention relates to a heat exchanger, in particular a refrigerant evaporator according to the preamble of claim 1.
  • Heat exchangers of this type have already been proposed by the applicant's earlier application P 35 02 619.7. Heat exchangers of this type have the advantage that, in contrast to heat exchangers with disk-shaped heat exchange bodies, the flat tubes do not have to be soldered or glued over their entire length, but only at their ends and at the connection openings, so that a significant simplification of manufacture can be achieved. Since in the proposed designs the flat tubes lie directly against one another with widened end parts, the arrangement of separate connecting tube sockets is also superfluous.
  • heat exchangers of the proposed type are therefore provided, in which according to the indicator of claim 1, turbulence inserts are provided in the region lying between the widened parts of the tubes, which fill the entire tube width. This enables a higher heat exchange performance compared to pipes in which the turbulence insert does not fill the full pipe width.
  • each flat tube extends to the narrow longitudinal sides in the shape of an ogive to the bends on the longitudinal edges of the flat tube, so that it is then possible to extend the widened part over the entire tube width. Due to the pointed arch-shaped extension of the expansion towards the end regions, the pipe material is stretched less there than in the middle of the parallel pipe walls. Overstretching with the risk of crack formation is therefore avoided.
  • This configuration then makes it possible in a simple manner to insert turbulence inserts with the width of the flat tubes axially into the open tubes and then to fix them in a known manner. It is also advantageous that no deformation occurs in the narrow end areas, where the weld seam is generally located.
  • the widened part in another method, however, it is also possible for the widened part to extend only over a part of the width of the flat tubes, although a certain pinch must then be provided in order to provide the full width of the turbulence insert in the flat tube.
  • the flat tube is therefore only finished after inserting a turbulence insert.
  • This method has proven to be very beneficial. It brings the advantage that the turbulence insert used in this way is also fixed in the flat tube after the deformation of the plate-shaped central part of the initially oval tube.
  • FIG. 1 to 3 show a heat exchanger (1) which is constructed from a plurality of flat tubes (2) which are placed directly next to one another and with their axes (5) aligned parallel to one another.
  • the flat tubes (2) are placed next to one another with widened parts (2a, 2b) provided at the ends and take up heat exchange fins (3) between them, which for better heat dissipation of the in the drawing plane in Fig. 1 on the flat tubes (2nd ) flowing past serve a heat exchange medium, especially air.
  • the widened part (2a) or (2b) of the flat tubes (2) is closed in the exemplary embodiment by caps (10) inserted on the end face. These caps are omitted from the lower two tubes of FIG. 3. It can be seen that the middle part (2c) of the flat tubes (2) is considerably narrower than the widened part (2a) and that the flat tubes provided with parallel walls have bends (8) in the area of their longitudinal edges, each of which extends into the parallel walls ( 4) pass over. It can also be seen from the figures that the widened part (2a) or analog (2b) has openings (6, 6 ⁇ ) in the parallel wall parts (4 ⁇ ).
  • Fig. 2 shows that the parallel walls (4 ⁇ ) of the expanded part (2a) run approximately in the area between the boundary lines (11) and that from these boundary lines to the outside, where less material is deformed by the ogival shape, also useful End wall parts (12) which run obliquely upwards outwards, while a lower-lying region is present in the region between the boundary lines (11).
  • This configuration ensures that even in the middle area, ie. H. in the area of the walls (4 ⁇ ) the material stretch can be kept within the permissible range.
  • FIG. 4 to 7 show another embodiment of a flat tube for a refrigerant evaporator, which is also provided with a turbulence insert (70), but is produced in a different way.
  • the end regions of a flat tube are not widened, but instead, as the upper part of FIG. 4, a tube (20 ⁇ ) with an oval cross section is selected as the starting material, the walls (40) of which are at a distance (b) from one another.
  • This oval tube has the length (B ⁇ ).
  • a turbulence insert (70 ⁇ ) in corrugated or zigzag shape is now inserted into an oval tube (20 ⁇ ) designed in this way.
  • This turbulence insert (70 ⁇ ) has a total length that is dimensioned such that it corresponds to the length (B) of the deformed part after the deformation of the tube (20 ⁇ ) described below.
  • This turbulence insert (70 ⁇ ) with the length (B) is therefore first, as the upper part of FIG. 4 shows, inserted axially into the tube (20), to the extent that it occupies the area (21) (see FIG. 5 and 6), which is then to be deformed. Once this has been done, this central area (21) is pressed together by rolling or pressing, in such a way that in this area the tube (20 ⁇ ) receives the thickness (d) and the Width (B).
  • This flat tube (20) designed in this way therefore has widened end regions which do not have the full width (B).
  • the turbulence insert (70) over the full length of the width (B), which, due to the deformation process, both assumes its extended position according to FIG. 4 and is secured axially in this position.
  • the parts (20a) and (20b) remaining as a result of this deformation process and widened with respect to the region (21) can be provided with openings similar to the openings (6) of the embodiment of FIGS. 1 to 3. In the exemplary embodiment, however, they are each provided with two openings (60) or (60 ⁇ ) which, when they are put together, establish the connection between the individual flat tubes (20).
  • outlets (61) projecting outward at the openings (60) are produced, for example, by a suitable stamping process.
  • This embodiment then has the advantage that only one type of flat tube (20) is required to build a flat tube evaporator or flat tube heat exchanger, which are soldered to one another.
  • the nozzle (61) are dimensioned so that they fit into the openings (60 ⁇ ).
  • the open pipe ends are closed by inserted caps (10).
