It should be noted that in the utility model embodiment, being more than or equal to the first preset temperature value in coolant temperature
(generally this first preset temperature value is calibration value, for example, 90 DEG C), is realized to radiator fan by starting hydraulic unit driver 300
200 driving, changes the heat radiation power of radiator 100 with this, because hydraulic-driven radiator fan can realize the electrodeless change of fan
Speed, realizes the regulation of the heat radiation power to radiator 100 with this, when requiring larger heat radiation power, improves radiator fan 200

It is not at rotary state, the simply rotation of radiator fan is not hydraulically operated device 300 and drives, but is operated in a constant speed
State.
It should be noted that research shows, the heat radiation power of radiator and the air mass flow magnitude relation flowing through its surface

Wherein, k is the coefficient of heat transfer of radiator, and unit is W m-2·K-1；A is the area of dissipation of radiator, and unit is
m2；Δ T is the MTD of coolant and air, and unit is K.
From formula B, the heat radiation power of radiator depends on the difference of coolant temperature and environment temperature, with environment temperature

Described hydraulic unit driver sends drive control signal.
It should be noted that the direct collection of barometric pressure sensor is atmospheric pressure, because atmospheric pressure is main and extra large
Degree of lifting has substantial connection, therefore can be converted into height above sea level, just can be calculated according to the height above sea level being converted to
Go out atmospheric density ρ.
It should be noted that described first controller 400 is according to the atmosphere pressure signal of input, ambient temperature signal and cold
But liquid temp signal, searches and described atmosphere pressure signal, environment temperature with driving in the corresponding table of dutycycle in default signal

Below in actual applications, the concrete application of the motor heat abstractor of the utility model embodiment is illustrated such as
Under.
As shown in Fig. 2 motor heat abstractor mainly includes：Entire car controller, oil pump, oil pump motor, hydraulic pressure
Motor, radiator fan, barometric pressure sensor S1, environment temperature sensor S2 and cooling-water temperature transmitter S3；Wherein, radiate
Fan is arranged on the radiator of motor system；Described cooling-water temperature transmitter S3 is arranged on the cold of motor system
But on liquid pipeline, described barometric pressure sensor S1, environment temperature sensor S2 and cooling-water temperature transmitter S3 all with described

It is connected to hydraulic motor, hydraulic motor is connected to fuel tank by fluid pressure line, and described hydraulic motor is directly connected with radiator fan.
Wherein, the principle of hydraulic-driven radiator fan is：Oil pump to be driven by oil pump motor, the high pressure of oil pump output
Oil gives hydraulic motor, fluid motor-driven radiator fan, exports cooling power.
Entire car controller constantly detects the atmospheric pressure of the ambient temperature signal of environment temperature sensor, barometric pressure sensor
Coolant temperature signal in force signal and motor system, entire car controller according to environment temperature sensor signal value T1,
Motor system coolant temperature T2, barometric pressure sensor signal P1, this three is inputted an interpolation table (i.e. above-mentioned institute
The signal said and the driving corresponding table of dutycycle), the driving dutycycle of the electromagnetic proportional valve in output oil pump.Drive dutycycle not
The difference of same representative driving current, thus changing hydraulic fluid flow rate, and then the operating pressure of change hydraulic motor, adjust hydraulic pressure
The rotating speed of motor, the final rotating speed changing radiator fan, carry out different cooling power outputs.
It should be noted that the input of interpolation table is environment temperature sensor signal value T1, motor system coolant
Temperature T2, barometric pressure sensor signal P1, output is the driving dutycycle of electromagnetic proportional valve.This interpolation table is in control logic
It is a scalar quantity, specific calibration value can be simulated demarcating by test-bed, is finally verified on real vehicle.
The demarcation trend principle of this interpolation table is that motor system coolant temperature T2 is higher, and environment temperature is also higher, and driving accounts for
The value of empty ratio is bigger, and then increases radiating fan rotation speed, increases cooling power；Motor system coolant temperature T2 is higher,
Signal P1 is lower for barometric pressure sensor, illustrates that vehicle is in plateau area, air is thinner, is got over according to formula B air mass flow
Little, so the value of driving dutycycle is bigger, and then increase radiating fan rotation speed, increase cooling power；Motor system cools down
Liquid temp T2 is higher, and the value demarcating driving dutycycle is bigger, and then increases radiating fan rotation speed, increases cooling power, makes driving
Electric system lowers temperature as early as possible.
It should be noted that the operation principle of this motor heat abstractor is：
When coolant temperature is less than certain value, such as 90 DEG C (calibration value), whole fan system is off position.
When entire car controller is more than 90 by the temperature that cooling-water temperature transmitter S3 detects motor cooling system
DEG C when, now entire car controller enable oil pump motor, allow it be operated in a certain fixed rotating speed, such as 3000rpm, now oil
Pump is started working under the drive of oil pump motor, and the hydraulic oil in fuel tank is pressurizeed, and becomes with certain pressure tool
The high pressure liquid force feed of standby acting ability.
For preventing radiator fan from repeatedly being switched with closed mode in work near a certain temperature value, so being set in
Coolant temperature stops enabling oil pump motor from dropping to more than 90 DEG C after 80 DEG C again.
If any one above-mentioned sensor failure or because other reasonses lead in motor heat abstractor
Electronic control unit cannot output control signal when, oil pump with maximum pump discharge work, such radiator fan is just with maximum speed work
Make, to prevent motor system temperature too high；And pointed out on meter panel of motor vehicle, to remind driver to process as early as possible
Maintenance.
