Definitions

  • cooling modules consist essentially of a coolant radiator, a refrigerant condenser, a charge air cooler and / or a transmission, power steering or engine oil cooler.
  • the cooling module is pre-assembled as a unit and then positioned and fastened in the front engine compartment of the motor vehicle, so that all heat exchangers can be acted upon by ambient air.
  • a fan or a fan blower is arranged in front of and / or behind the cooling module.
  • the heat exchangers are interconnected by suitable fasteners, wherein one of the heat exchanger, z. B. the coolant radiator acts as a module carrier and is supported in the motor vehicle.
  • the fasteners often consist of plastic latching elements, which on plastic collection boxes of the heat exchanger, z. B. coolant boxes or charge air boxes are integrally molded. Insofar omitted additional fasteners such as screws or bolts.
  • Transmission oil cooler which also belong to a cooling module, are often housed in the coolant tanks of the coolant radiator, as z. As shown in EP 866 300 A2 of the applicant. However, the size and performance of such built-in transmission oil cooler depends on the size of the coolant boxes and thus limited.
  • a consisting of a coolant radiator, a refrigerant condenser and steering oil cooler cooling module was known, in which the individual heat exchangers are held together by laterally arranged so-called module carrier made of plastic and supported against the vehicle.
  • the module carriers are formed as a kind of brackets, which surround the heat exchanger laterally, and have a complicated fissured surface in order to enclose the heat exchanger or their collection boxes tight.
  • It is an object of the present invention to provide an arrangement for mutual attachment of saucer of the type mentioned above, which allows a compact design, secure positioning of the heat exchanger to each other and easy installation of the entire unit.
  • a relative movement of the heat exchanger to each other in particular in the horizontal direction is thereby preferably taken by means of Langlöchem or the like and / or clip connections between the mounting rails and one or more heat exchangers.
  • the mounting strips are attached to headers of heat exchangers, as these, especially if they are made of plastic, offer favorable mounting options.
  • the mounting strip can also be used on existing fasteners to the headers, z. B. snap connections can be adjusted. This has the advantage that the tools of existing, mass-produced collection boxes need not be changed. This also gives the advantage that further or otherwise designed, z. B. larger heat exchanger can be added by means of the mounting strip using existing attachment points in the unit.
  • the mounting rail has various attachment and receiving points for non-positive or positive reception of heat transfer, for example, openings for screw or locking elements for snap connections.
  • the Mounting rail can - depending on the number and size of the heat exchanger to be fixed - extend over the entire length of the heat exchanger or only partially.
  • the mounting strip is designed as a plastic injection-molded part, which allows a simple, inexpensive and adapted to the respective heat exchanger in the form of production.
