Step 201: obtain main primary hot(test)-spot temperature, the secondary hot(test)-spot temperature of power supply and power input current value.
In the present embodiment, main primary hot(test)-spot temperature, the secondary hot(test)-spot temperature of power supply are the temperature of the device that in main primary side and primary side hardware circuit, heat sensitivity is the highest.
Wherein, the magnitude of voltage that main primary hot(test)-spot temperature, the secondary hot(test)-spot temperature of power supply can be tested out by thermistor end in power supply calculates.
Step 202: determine the first rotation speed of fan value required for main primary hot(test)-spot temperature, the second rotation speed of fan value required for the secondary hot(test)-spot temperature of power supply and the 3rd rotation speed of fan value required for power input current value respectively.
In the present embodiment, the determination of the first rotation speed of fan value required for main primary hot(test)-spot temperature can adopt the linear approximate relationship that band bound is saturated, as shown in Figure 3, such as, below 25 DEG C, limit rotation speed of fan is about 1800RPM, and rotation speed of fan keeps completely transferring about 18000RPM to more than 80 DEG C, between 25 DEG C to 68 DEG C according to rotating speed between 1800RPM to 9000RPM with temperature value linear change, between 68 DEG C to 80 DEG C according to rotating speed between 9000RPM to 18000RPM with temperature value linear change;
The determination of the second rotation speed of fan value required for the secondary hot(test)-spot temperature of power supply also can adopt the linear approximate relationship that band bound is saturated, as shown in Figure 4, such as, below 25 DEG C, limit rotation speed of fan is about 1800RPM, and rotation speed of fan keeps completely transferring about 18000RPM to more than 80 DEG C, between 25 DEG C to 68 DEG C according to rotating speed between 1800RPM to 9000RPM with temperature value linear change, between 68 DEG C to 80 DEG C according to rotating speed between 9000RPM to 18000RPM with temperature value linear change;
The determination of the 3rd rotation speed of fan value required for power input current value can adopt power input current value control mode, as shown in Figure 5, such as, being less than 1A limit rotation speed of fan at input current is about 1800RPM, when input current is greater than 8A, rotation speed of fan keeps completely transferring about 18000RPM to, and rotation speed of fan presses current value linear change between 1A to 8A.
