Definitions

  • the invention relates to a brazed capacitor for a motor vehicle air conditioning system according to the preamble of claim 1, as for example in the US 5,509,473 is described.
  • Soldered condensers for automotive air conditioning systems consist of a Kondensanzetz and arranged on both sides of the network manifolds having a refrigerant inlet and a refrigerant outlet for a refrigerant inflow and a refrigerant outflow line.
  • holding elements are attached to the headers or also to the side parts of the condenser (between the headers), e.g. B. in the form of retaining plates with eyelets or retaining pins for support in an associated vehicle-mounted bearing - known by the utility model DE 295 09 565 U1 the applicant.
  • the condenser is placed in front of a coolant radiator of the vehicle and attached directly to it.
  • the refrigerant lines of the condenser which are made of aluminum tube, are fixed to the condenser, to which so-called tube holder are provided, which are also soldered to the capacitor or otherwise secured thereto.
  • the holding elements for supporting or suspending the condenser and the tube holding devices for fastening the refrigerant lines are each separate components which are manufactured individually and are arranged at separate locations on the condenser. For example, such an arrangement of holding elements and Rohrhaltem from the earlier application with the file number EP 03290190.2 in which the capacitor is soldered "in one shot" with the holders and tube holders.
  • a capacitor with support brackets has been disclosed, which are fastened to the network of the capacitor by riveting.
  • the Applicant has disclosed a soldered heat exchanger in the form of a capacitor, in which the holders for supporting or suspending the capacitor are positively and materially connected to the collecting tubes. As a result, a soldering in one operation and without additional soldering aids is also possible.
  • the holding elements fastened to the condenser are designed so that they can perform two different functions, namely, first, the support or suspension of the condenser and, secondly, the support of a refrigerant line.
  • the advantage is achieved that the number of parts, in particular the holding parts is reduced and the production is simplified.
  • This also reduces the cost of the capacitor.
  • the capacitor according to the invention instead of - as in the prior art - a holding element and a tube holder, both of which are soldered to the capacitor, only needs a combination holding element according to the invention, which performs both functions simultaneously.
  • the refrigerant pipe is positively and materially connected to the holder.
  • recesses are provided in the holder, which are adapted to the profile of the refrigerant line and can record and hold this form-fitting manner.
  • the holder according to the invention and the refrigerant line can thus be prefixed for the soldering process without additional aids, so that the entire capacitor with holders and refrigerant line can be soldered in one shot.
  • the refrigerant pipe is inside, ie adjacent to the manifold, while the fastening part of the holder is arranged outside, z. B. in the form of a mounting hole. This provides the advantage that both functions do not interfere with each other.
  • Fig. 1 shows a section of a capacitor 1 for a motor vehicle air conditioning, not shown.
  • a manifold 2 which is preferably constructed in two parts, ie consists of a cover part 2a and a bottom part 2b.
  • the bottom 2b receives pipe ends 3 of a capacitor network, not shown.
  • a holder 4 is fixed, ie it engages with projections not shown in corresponding openings of the lid 2a, as is known from the prior art, in particular the earlier application with the file reference EP 03290190.2 but also in the aforementioned utility model DE 295 09 565 is known.
  • the holder 4 is formed as a sheet metal part with a U-profile, which has a central web 4a and two lateral legs 4b, 4c. In the region of the web, a fastening opening 5 is arranged in the form of a window. Parallel to the longitudinal direction of the collecting tube 2, a refrigerant line 6 is arranged with a round cross section, which is received by (not visible here) recesses in the legs 4b, 4c.
  • Fig. 2 shows the execution according to Fig. 1 from the back, with like reference numerals being used for like parts.
  • a recess 7 which has an approximately semicircular profile, ie a half profile of the refrigerant pipe 6.
  • a same half-profile, but not visible, is arranged in the lower leg 4b, so that the refrigerant line 6 form-fitting manner of the holder. 4 is held.
  • the window 5 is used to attach the capacitor 1 in the motor vehicle, not shown, for. B. on a likewise not shown coolant radiator in the engine compartment of the motor vehicle.
  • the condenser 1 is - as known - connected via the refrigerant line 6 and a further refrigerant line, not shown here, to a refrigerant circuit, also not shown, of a motor vehicle air conditioning system.
  • All parts of the condenser, ie network, consisting of flat tubes and corrugated fins, manifold 2, holder 4 and refrigerant line 2 are made of aluminum materials and are prefabricated and prefixed so that they can be soldered without additional soldering agent in a soldering oven, not shown substantially.
  • the refrigerant pipe 6 is soldered after the soldering process with the holder 4 and this with the manifold 2.
  • Fig. 3 shows an embodiment, which is not the subject of the claims, with a collecting tube 8, to which a holder 9 is attached.
  • This has a relatively wide, extending in the longitudinal direction of the collecting tube 8 base part 9a, from which approximately at right angles bent legs 9b, 9c depart.
  • the holder 9 is - as previously in the embodiment according to Fig. 1 and 2 described - inserted with not shown pins or feet in the manifold 8 and soldered to it.
  • To the base part 9a is followed by a slightly angled holding part 9d, in the outer part of a rectangular mounting opening 10 is arranged. Behind the holding part 9 d, a refrigerant line 11 is arranged, which in turn runs parallel to the longitudinal direction of the collecting tube 8.
  • the refrigerant line 11 is located - which is not clearly visible in this illustration - in a curvature 12 of the holding member 9d and thereby experiences a certain fixation. After soldering, there is a fixed solder joint between the refrigerant line 11 and the holder 9.
  • Fig. 4 shows the embodiment according to Fig. 3 in a rear view, ie the refrigerant pipe 11 is located in the drawing plane in front of the holder 9 and its holding part 9d. It can be seen in this view that the wide base 9a in conjunction with the U-legs 9c, 9d enables a solid, stable attachment of the holder 9.
