220V AC Cooling Fan forced up wind

"220V AC Cooling Fan" is used to fill the radiator to force air through the wind speed to meet the cooling needs of the engine moderately. Forms of work from the cooling fan, the fan control mode has three kinds:
    One is suitable for mechanical drive control large vehicles and heavy-duty vehicles;
    Second, regardless of the engine ECU, controlled electric monitoring environmental parameters alone control mode;
     Third, integrated intelligent control "220V AC Cooling Fan" integrated engine, air conditioning, compressors, vehicle speed and other parameters of information.
     The former is the use of a mechanical transmission principle. Or directly driven by the engine crankshaft, or driven by "220V AC Cooling Fan" by the engine belt; the latter two only reflects the true sense of the engine cooling fan control technology.
