Definitions
- the invention relates to a radiator frame with at least one electrically driven fan, in particular for cooling the drive units in a motor vehicle.
- the at least one fan is usually integrated in a radiator frame which is attached to the front end module of the motor vehicle directly to the radiator and which serves to form a defined air flow substantially parallel to the axis of rotation of the fan wheel and thus optimum cooling.
- the fan is coupled directly to the drive motor, whose speed is preferably regulated as a function of the required cooling capacity.
- DE 196 12 679 C2 discloses a fan with a fan with a cup-shaped hub, which is placed over the housing of the drive motor and rotatably connected to the drive shaft of the electric motor.
- the windings thereof are connected via a connecting cable to the control electronics accommodated in a separate electronics housing, which is fastened to the radiator frame outside the outer ring of the fan wheel.
- the connection cable between them is arranged on a mounting arm for the electric motor.
- a cooling fan is described, in which the control electronics for the electric motor outside the outer ring of the fan wheel on the radiator frame is arranged in an electronics housing.
- the control unit can also form a structural unit with the drive motor and be housed in a common housing with this, which has the advantage. That the fan has a smaller footprint, is well electromagnetically compatible and less prone to failure, as described in DE 100 44 066 A1.
- the radiator frame must have a power supply line for the control unit and the drive motor, which is constantly under tension.
- an injection-molded plastic radiator frame with two fans is known, the electrical and electronic supply is performed by lines in Conduction channels are guided.
- the guided to the fans electric cables with plugs are connected to each other and to the electrical system, the plugs are in particular also set on the moldedméerzarge mounts to this.
- radiator frames may be the piping arrangement and disassembly. If the distance of the radiator frame to the radiator and thus also the ducts to this is only a few millimeters, there is a risk that both the lines and the cooling fins of the radiator are damaged if the lines are insufficiently fixed, which in particular at live lines the risk of consequential damage.
- the ducts can be designed as latching or clamping channels and be provided with locking elements, in which the lines are clipped, but which require a very high effort in the wiring. Slipping out of the lines from the ducts is favored by the relatively high tolerances in the cable length, which are necessary due to production.
- cable ties can be used, which partially enclose the cable ducts and the lines laid in them, whereby, however, the assembly effort is increased.
- the plugs are each secured by means of a latching connection to the radiator frame. There is a risk of breaking off the locking lugs.
- the invention consists in that in a radiator frame with at least one electrically driven fan with an electric motor and a fan wheel, which is provided in a known manner with a receiving opening for the fan and a holder formed in this for the electric motor connected to the fan, wherein the Holder via connecting ribs od.
- the lines Connected to the frame body and electrical lines are led to the holder, the lines as separate interconnects, especially in the form of a completely or partially overmolded with insulating plastic and relatively rigid insert composite of stamped conductors, integrated into this or are molded onto these, wherein the ends of the lines are formed to plug-in connections. These can be surrounded by a molded onto the radiator frame connector housing.
- radiator frame has the advantage that the integrated lines are protected from damage. Further advantages are an increase in process reliability during assembly and an increase in operational safety, which is given in particular by reducing the risk of damage to the electrical lines. In addition, the production time for a radiator frame provided with a fan as well as the material and manufacturing costs are reduced. Finally, the plastic-coated electrical lines are hermetically sealed against the environment, especially moisture and pollution.
- the lines are advantageously poured in the area between the frame body and the bracket in an already existing connection rib.
- a plug housing for the motor-side plug-in connections is formed in the region of the connection point of the connecting rib on the holder, which is also arranged adjacent to a mounting element for the motor formed on the holder.
- the insert composite is produced in that a stamped and bent part is produced from a metal sheet with interconnected and interconnected via individual connecting webs interconnects and the plug-in connections. Thereafter, the interconnects additionally fixing plastic bridges are sprayed on and then removed the connecting webs, in particular by cutting or punching tools.
- the insert composite produced in this way is integrated into the radiator frame and thereby overmoulded again. This repeated overmolding ensures that the lines in the insert composite and this are hermetically sealed.
- the radiator frame is advantageously produced by injection molding.
- the injection mold is designed so that the plug-in connections remain free.
- physical foaming by the MuCell injection molding process (DE 698 05 957 12) is also suitable as an injection molding process, the cost advantages due to lower pressures in the injection molding tool, a reduction of the cycle time, a material saving associated with a weight saving of up to about 20%, and also a higher quality of the manufactureddeerzargen due to a lower distortion of the same, associated with less waste, brings.
- the size of the machine is reduced compared to the usual injection molding machines, whereby further advantages are given.
- a radiator frame made with this method then consists of a microcellular thermoplastic foam.
