Beschreibung
Zusammenfassung:	The utility model relates to a truck cooling fan's control system, include: air conditioning switch, engine control ware, high -low voltage switch, medium -voltage switchgear, first relay and second relay. Air conditioning switch's one end links to each other with the battery positive voltage, and air conditioning switch's the other end links to each other with high -low voltage switch's the input and the input of first relay respectively. The output of first relay links to each other with medium -voltage switchgear's input, and the coil end of first relay concatenates between high -low voltage switch's output and whole car ground. The input of second relay links to each other with the first output of engine control ware, and the output of second relay links to each other with the first input end of engine control ware, and the coil end of second relay concatenates between medium -voltage switchgear's output and whole car ground. When air conditioning switch is closed, if high -low voltage switch disconnectio
