- the invention is based on the object
- the object is achieved according to the invention in that at least the heat sink of the rectifier is structurally or spatially separated from the alternator, wherein the heat sink is provided in the region of a fan or the cooling body is associated with a fan. This ensures that the rectifier can be optimally cooled regardless of the given power class.
- the space available on the internal combustion engine can be optimally utilized for the alternator.
- the available on the alternator cooling capacity for the alternator is available.
- the fan can be an existing radiator fan or an additional external fan.
- the rectifier is associated with a controller, wherein the controller between the heat sink and the alternator is arranged on a frame part or frame longitudinal member of the internal combustion engine.
- the controller is provided with a separate electrical coupling so that it does not have to be located directly on the rectifier or on the alternator.
- the ventilator designed as a cooling fan has a speed dependent on the DC voltage, wherein when the DC voltage drops below a critical value U m i n the cooling fan generates a speed increase.
- a sufficient cooling capacity of the radiator fan for the rectifier is ensured at electrical overloading of the alternator and the resulting voltage drop.
- the control of the hydrostatically formed radiator fan is carried out via a bypass proportional valve.
- the other control parameters are the charge air and the coolant temperature of the internal combustion engine.
- the parameters are from a Motor control output as voltage partial value of vehicle electrical system voltage.
- the vehicle electrical system voltage thus represents an indirect control parameter for the fan control.
- the heat sink is arranged on at least one spacer sleeve on the rectifier housing formed of plastic, wherein the spacer sleeve is designed as a voltage tap for the DC voltage network.
- the heat sink is connected to the rectifier housing by means of plastic screws. The mechanical attachment of the heat sink is thus optimally coupled with the electrical insulation, since the diodes are mechanically and electrically coupled to the respective heat sink.

- the ventilation slots are in this case aligned according to the cooling ribs or have with respect to the flow direction of the cooling air on a similar projection image, so that an optimal convection or flow of cooling air between the cooling fins and out of the rectifier housing is guaranteed.
- a cable duct is provided between the rectifier, the controller and / or the alternator, the cable duct at least partially formed as an electromagnetic shield.
- the relatively large alternating current in the electrical connecting line between the rectifier and the alternator generates a non-critical AC field, which leads to the emission of an electromagnetic field. An additional shield is therefore not necessary.
- the heat sink has a plurality of cooling fins which are connected to each other at least on one side and / or attached to a rectifier housing and formed open in the direction of the perpendicular down. Due to the open training, the steady accumulation of dirt can be prevented as it falls down.
