Definitions

  • the invention relates to heat exchangers, in particular for motor vehicles, with a one-piece connection water tank which is divided into a flow and return space and a one-piece deflection water tank made of plastic, which are connected to one another via a tube bundle of water tubes made of metal held together by air-guiding fins, the tube ends of which are connected via an in groove-shaped depressions which widen the tube openings and are attached to the outside of the bottoms of the water tanks and are sealed and sealed.
  • Heat exchangers of the type mentioned are already known from DE-A 2302769 and DE-A 23 02 770.
  • one-piece connection and deflection water boxes made of plastic are used, which, in order to be able to fasten the pipe ends in a sealed manner to a hardening plastic material which is introduced into the pipe openings via groove-shaped depressions which widen into the pipe openings, with these recesses correspondingly supplementing them
  • Bottom covers must be provided. These bottom covers must be fixed in a suitable manner with respect to the water tanks so that after the tube ends of the tube bundle are inserted into the tube openings and the subsequent injection of hardening plastic material into the closed, groove-shaped depressions, an uncontrolled escape of the plastic material is avoided.
  • This embodiment of a known heat exchanger thus has the disadvantage that additional tool, material and assembly effort is required for the necessary bottom covers.
  • water boxes are used which are divided along a vertical wavy cut surface containing the pipe openings.
  • the cut surface is again provided at the height of the pipe openings with groove-shaped depressions which, after the two parts of the water box have been joined together, again form groove-shaped depressions which widen the pipe openings and into which a hardening plastic material is injected after the pipe ends have been inserted into the pipe openings.
  • This embodiment of a known heat exchanger avoids an increased outlay on materials, but makes an increased outlay on tools necessary for the divided water boxes.
  • the cutting surface running over the entire circumference of the water boxes must be sealed using the hardening plastic material, which on the one hand results in a high expenditure of material on hardening plastic material and on the other hand the likelihood of possible leaks is greatly increased by the large length of this sealing joint.
  • tie rods had to be used to maintain a constant contact pressure and in the latter case, the corresponding area of the water tank and the water pipes had to be heated to a correspondingly high temperature, which made it possible for the molten solder material to supply a metallic bond between the flux to manufacture the two components.
  • the object of the invention is to improve a heat exchanger of the type mentioned in such a way that simple tools and little material are required for the production of the one-piece water boxes from plastic, the length of the sealing joints remains limited to the absolutely necessary minimum and the curable plastic material can be introduced in a simple manner and can be brought into intimate connection with both the inside and the outside of the water pipe ends.
  • the outside of the bottoms of the water boxes are provided with a plurality of pipe sockets, which are surrounded by spaced ring webs, the curable plastic material being arranged in the axially open annular grooves formed between the pipe neck and the ring webs, into which the pipe ends, which can be plugged onto the pipe socket with their flared collars, enable the one-piece water boxes to be made of plastic with simple tools and little material, the length of the sealing joint is limited to the absolutely necessary minimum, and the introduction of the hardenable plastic material is simplified, thereby simplifying the fact that the inside diameter of the pipe ends is slightly larger than the outside diameter of the pipe socket and the outside diameter of the flared collar is slightly smaller than the inside diameter of the ring webs, it is ensured that this is already in the ring grooves b As a result of the curable plastic material, the pipe ends are not only wetted on the outside, but also pressed into the space between the pipe socket and the inner wall of the pipe ends, since the flared collar of the pipe socket takes on
  • Terokal 3919 registered trademark

  • the construction according to the invention requires a minimum of tool, material and assembly costs.

  • a foam seal 6 encompassing the heat exchanger on its circumference is used, for example, to arrange the heat exchanger in a heater housing of a motor vehicle.
  • the water boxes 1 and 2 which are made in one piece from plastic, are provided on the outer sides of their flat floors 8 and 9 with a number of towering pipe sockets 10 corresponding to the number of water pipes 4, which are surrounded by ring webs 11 running at a distance from them.
  • the curable plastic material 5 for example Terokal 39 19 (registered trademark) from Teroson, can be introduced via a corresponding distribution device.
  • the water pipes 4 made of metal are designed as flat pipes onto which a large number of air-guiding fins 3 made of aluminum are attached and subsequently fixed by expanding the pipes under internal pressure.
  • the pipes are expanded at their pipe ends 13 by means of corresponding mandrels and provided with a collar 14 which is flared out.
