Definitions

  • the invention relates to a metallic collecting box for a heat exchanger, in particular for motor vehicles according to the preamble of claim 1 Pa ⁇ .
  • Metallic collecting boxes are used today for heat exchangers of motor vehicles, in particular soldered radiators and soldered coolant coolers, for reasons of recycling and strength.
  • Prior to this development to unmixed heat exchangers used for the collection and distribution boxes of radiators and coolant radiators Kunststoff ⁇ material boxes, which u. a. had the advantage that one could inject ein ⁇ piece connectors to the plastic boxes.
  • This possibility does not exist with metal water boxes, which are preferably produced from aluminum sheet by chipless forming such as deep drawing. Rather, metal boxes for heat exchangers have only an inwardly or outwardly formed sheet metal collar, which is soldered to a pipe coupling, via which a connection to a heating or cooling circuit of the motor vehicle is possible.
  • Inlet nozzle and an outlet nozzle are soldered.
  • These connecting pieces are usually used as pipe couplings, so-called plug-in formed couplings, as was known from DE 44 03 402 A1 of the Applicant.
  • the pipe coupling on the one hand on a cylindrical portion which ge inserted into a collar of the metallic water box and is soldered tight with this.
  • the pipe coupling also called connecting piece
  • an extended area in which a pipe end of a heating pipe plugged can be sealed by means of a sealing ring and axially fixed by means of a plug-in fork.
  • This type of pipe connection to a metallic collecting box requires a large number of parts, ie a collecting box with a molded collar, a pipe coupling (connecting piece) which can be soldered to the collecting box, including sealing and locking means, and a pipe end of the connecting line.
  • At least one connecting piece can be produced in one piece from the collecting box or from its output board.
  • the connecting piece (s) are thus formed from a sheet-metal blank by non-cutting shaping such as punching, multi-stage deep drawing and / or compression.
  • non-cutting shaping such as punching, multi-stage deep drawing and / or compression.
  • the connecting pieces can be arranged on the longitudinal sides or on the top of the collecting tank.
  • the connecting piece is formed circular cylindrical, which is easiest darstel ⁇ by chipless forming process steps len.
  • the connecting piece has a circumferential bead, which can preferably be produced by upsetting the connecting piece.
  • the connecting piece ei ⁇ nen outer diameter D and a length L, wherein the ratio of length L to diameter D in the range of 0.8 to 1, 0, preferably at 0.9.
  • a connecting piece with these dimensions offers the possibility for a pipe connection with means known from the prior art.
  • the connecting piece according to the invention in particular with circumferential beading, can be connected to a heating or cooling circuit of a motor vehicle by means of a pipe coupling known per se.
  • the pipe coupling can spielvati be fixed by means of plugging fork with respect to the bead.
