The correction factor answered；
The product of the initial speed Yu the correction factor is calculated, to obtain the rotating speed of target；
Wherein, rotation speed of the fan control arteries and veins spectrum is the engine under the initial height above sea level in unit
In the initial target heat that is removed by the cooling equipment that is mounted thereon with variation of ambient temperature curve.
Specifically, Fig. 2 is electric control silicone oil fan control logic schematic diagram provided in an embodiment of the present invention.Referring to fig. 2, the control
The final revolving speed of fan is common by rotation speed of the fan control arteries and veins spectrum and the rotation speed of the fan correction factor based on atmospheric pressure during system
It determines.
In the present embodiment, when calculating the revolving speed of control electric control silicone oil fan, engine is obtained by measurement first and is worked as
The current environmental temperature of preceding work.Then the corresponding initial mesh at a temperature of obtaining the current environment in rotation speed of the fan control arteries and veins spectrum
Mark heat.It should be noted that rotation speed of the fan control arteries and veins spectrum is engine under the initial height above sea level in unit
In the initial target heat that is removed by the cooling equipment that is mounted thereon with variation of ambient temperature curve.By current
When environment temperature searches target heat, need to guarantee during obtaining rotation speed of the fan control arteries and veins spectrum, engine used
Power it is identical as the power of the engine currently calculated, and the water yield of cooling water is identical.
