  • the invention relates to a collecting box, in particular a heat exchanger of a motor vehicle, comprising a tube bottom comprising first contact surfaces, with a box part comprising second contact surfaces, in which the tube sheet and the box part are soldered together at soldering areas, and in which the first contact surfaces and the second contact surfaces Can form soldering areas. Furthermore, the invention relates to a heat exchanger, in particular a condenser, a motor vehicle with a heat exchanger block and with manifolds, in which cooling tubes of the heat exchanger block open into the manifolds.
  • Generic headers for heat exchangers are well known in the art and often consist of at least two moldings, which are soldered together, so that the collecting tank can be formed in particular liquid-tight and pressure-resistant.
  • the aforementioned moldings is usually a tube plate and a box part or a lid of the header tank.
  • a heat exchanger with an at least two-part collection box of a bottom and a lid wherein the bottom and the lid are soldered together at common contact surfaces.
  • the collecting tank is constructed particularly resistant to pressure
  • the bottom has edge strips, so that the cover can be inserted into the ground and undergoes lateral guidance by means of the edge strips.
  • further contact surfaces are provided along the central axis of the collecting box, which provide additional soldering areas on the collecting box in addition to the edge strip area.
  • edge strips can also be a good pre-fixing the lid on the floor succeed, so that the contact surfaces for forming the soldering areas on the bottom and lid are securely stacked so that they cover well during transport of the components together prefixed and during the soldering process can.
  • a collection box in this respect also at least from a bottom and a lid, which form at common contact surfaces soldering areas where they are soldered together.
  • at least one of the two moldings has lug-like structures which can at least partially surround the floor inserted in the lid, so that the floor is no longer unintentionally counter to a loading direction can solve from the lid of the collecting tank.
  • a cover of a header tank and a bottom of the header tank are crimped lengthwise before brazing at their edge portions, so that the cover and bottom are well pre-fixed for first handling of the header tank.
  • a latching connection is provided in a longitudinal dividing wall region of the collecting box, which extends over the entire length of the longitudinal dividing wall region, wherein latching noses of a first molded part can engage in undercuts of a second molded part of the collecting box, whereby the cover and bottom of the collecting box well prefixed together in this longitudinal dividing wall area are.
  • the object of the invention is achieved by a collecting box, in particular a heat exchanger of a motor vehicle, having a tube bottom comprising first contact surfaces, comprising a box part comprising further contact surfaces, wherein the tube sheet and the box part are soldered together at soldering areas, and in which the first contact surfaces and the second contact surfaces can form the soldering areas, wherein the collecting box is characterized by means for securing the contact, by means of which in the soldering areas a critical removal of the contact surfaces is prevented from each other.

In this context, it is understood that not all contact surfaces between the mold components necessarily form soldering areas.
  • the means for securing contact are arranged on a longitudinal dividing wall region of the collecting tank.
  • a longitudinal partition wall portion may divide the collecting box into two main channels. In particular, this makes it ideal for placing contact surfaces both on the tubesheet and on the box part of the header tank, wherein the pressure resistance of the header box can be particularly high when the tubesheet and the box part are soldered together there.
  • the contact-securing means can be provided in a structurally simple manner, since the means for securing the contact are arranged within the soldering areas. Although this reduces the respective soldering area, but this can be compensated with a better solder joint. In particular, if not the entire soldering area is required to meet the strength requirements.
  • the quality of the solder joints at the soldering areas of the collecting box is increased by the fact that the means for securing the contacts have solder initiation formations.
  • Such Lötinitialmaschinesgetrucke can ensure particularly reliable contact between the first contact surfaces and second contact surfaces, starting from which a solder joint can form excellent.
  • the means for securing contact surveys within the first contact surfaces are also possible.
  • a pin of a tube plate is inserted into a hub, which may be formed as a through hole on a box part, such that a free end of the pin is accessible from the outside of a header, so that the pin are pressed in the hub from the outside can.
  • a particularly close-fitting contact fixation can be achieved.
