Definitions

  • the invention relates to a heat exchanger tube block with at least two collector tubes with a C-shaped cross section, which each have a continuous longitudinal slot, and with flat tubes inserted into the longitudinal tube slots.
  • Pipe blocks of this type are used, for example, for heat exchangers used in automotive air conditioning systems.
  • Heat exchanger tube block described which is a stack of rectilinear Includes flat tubes, each end in one Longitudinal slot of two header pipes are inserted, which are parallel arranged along two opposing sides of the block are.
  • the header pipes can be made from a respective Tube blank into which the continuous longitudinal slot is cut by milling or the like is introduced, or by bending one each sheet metal strip in the desired C-cross-sectional shape be made.
  • the invention is a technical problem of providing a new type of heat exchanger tube block of the type mentioned Type based on which is relatively small Effort with the required fluid tightness and pressure resistance can be made.
  • the invention solves this problem by providing a Heat exchanger tube blocks with the features of the claim 1.
  • the pipe block according to the invention includes an end plate element, which has several C-shaped openings and plugged onto one end side of the at least two manifolds is, each of these manifolds fluid-tight into one the openings are inserted.
  • the C-shaped header section suitable C-contour of the openings enables without any problems the fluid-tight insertion of the header pipes into the openings, by placing the end plate element on the header pipes is pushed on and the respective manifold through the associated opening passes, after which the remaining Gap between the collecting tube and the opening edge, for example by means of Soldering is sealed in a fluid-tight manner.
  • header pipes have a continuous longitudinal slot, you can, if required, without machining the pipe alone made from a flat blank by a bending process become.
  • heat exchanger tube block includes another end plate element, the several Has openings for inserting a respective manifold and on the other end side of the at least two manifolds is plugged in, the openings being designed such that the internal flow cross-section of the push-through manifolds at least partially leave blank.
  • the tube / fin block shown in FIG. 1 can be used, for example, for an evaporator of a motor vehicle air conditioning system, and it can be designed without any problems with a pressure resistance which is required for systems which work with the refrigerant CO 2 .
  • the tube / fin block is of the flat tube serpentine type and contains two serpentine multi-chamber flat tubes 1, 2, which are arranged side by side between two side end plates 3, 4. Heat-conducting corrugated fins 5 are introduced in a conventional manner between the individual serpentine windings of the flat tubes 1, 2.
  • the two serpentine flat tubes border in the center of the block 1, 2 with their inner end sections 1a, 2a Touching each other.
  • the two contiguous Flat tube end sections 1a, 2a open at the top in FIG. 1 Block side in a first manifold 6 with a C-shaped cross section.
  • the other, outer end sections 1b, 2b of the two Serpentine flat tubes 1, 2 are led out on the upper block side, by a first right-angled bend towards each other to the inside and in the middle of the block by a second bend down and into a second manifold 7 inserted with a C-shaped cross section, which with a small Distance above the first manifold 6 parallel to this is arranged.
  • the collecting tubes 6, 7 have to accommodate the flat tube ends each have a continuous longitudinal slot 10, 11. Latter can be manufactured very easily without machining can be realized in that the two manifolds 6, 7 by a forming round rolling process from one plan sheet metal strips are made to the desired C cross-sectional shape while leaving the respective continuous Longitudinal slot 10, 11 is bent. This brings savings work processes and also avoids the risk of that chips get into the inside of the collecting tube and later Operation can lead to blockages in the refrigerant circuit. Solder-plated material is preferred for the header pipes 6, 7 used.
  • each of the two header ends 12, 13 provided in the example shown are realized as 8-shaped, perforated plates.
  • the 4 and 5 show the two end plates 12, 13 in Individual representation. From this it can be seen that they are fulfilling are punched differently for different purposes.
  • the one end plate 12 shown in FIG. 4 is included two C-shaped through openings 14, 15 provided which the C-shaped cross-sectional contour of the manifolds 6, 7 and in their mutual position of the relative position of the two manifolds 6, 7 correspond to each other.
  • This first end plate In this way, 12 serves as an axially fluid-tight closure Element. For this, it will be on the right in Fig. 3 Front of the two header pipes lying parallel to each other 6, 7 pushed until it is against the side in the manifolds 6, 7 inserted flat tube ends, the Collecting tubes 6, 7 through the through-openings with the same cross-sectional shape 14, 15 pass through.
  • Front ends of the two manifolds 6, 7 is, as in Fig. 3rd shown, one connecting tube 18 widened at the end, 19 axially pushed on.
  • the connecting pipes 18, 19 meet with its forehead butt against the end plate 13, that in turn with a butt joint against the in the manifolds 6, 7 inserted flat tube ends.
  • These butt joint connections fill up during the soldering process, in which the entire Pipe block complex is soldered tight, fluid-tight with solder.
  • the end plates 12, 13 preferably also exist made of solder-plated material.
  • the other end plate 13 leaves its circular through openings 16, 17 the inner Flow cross section of the two manifolds 6, 7 free, so that on the corresponding connection side on the left in FIG. 3 undisturbed fluid connection of each of the two connecting pipes 18, 19 with the associated manifold 6, 7 is given.
  • the parallel Chambers of the two serpentine flat tubes 1, 2 in fluid communication. In this way, the refrigerant used can a connecting pipe and the associated manifold in parallel the two serpentine flat tubes 1, 2 are distributed where it in the pipe block depending on the selected connection direction from the inside flows outward or inward from the outside, to subsequently collected in the other collecting pipe and over the other connecting pipe to be dissipated.
  • the heat exchanger tube block according to the invention can be manufactured with relatively little effort.
  • the collecting pipes have a continuous Have longitudinal slots, which is technically simple is feasible and the insertion of the flat tube ends is very simple makes, since no tolerances in the axial direction are observed have to.
  • the axial termination is advantageously by causes the two end plate elements after insertion of the flat tube ends in the longitudinal tube slots the manifolds can be pushed on.
  • heat exchanger tube block according to the invention not only for evaporators of automotive air conditioning systems suitable, but for any other heat exchanger with a tube block structure with several manifolds and flat tubes inserted into it.
  • a pipe block can be used to implement the invention rectilinear flat tubes can be provided, and / or it can more than two parallel manifolds may be provided, at least an axially sealing end plate element, the corresponds functionally to the end plate 12 from FIG. 4, on two or possibly more of these manifolds is plugged in for the purpose of axial sealing.
  • the end plate element of the type in which the internal flow cross section of the header pipes is at least partially released as is the case with End plate 13 of FIG.
  • a Another embodiment of the invention includes several in a block depth direction perpendicular to the drawing plane of Fig. 1 pipe block units arranged one behind the other in FIG. 1 shown type, with the two manifolds over the entire Extend block depth and together from the one behind the other Pipe block units can be used.
