The subsequent embodiments will not be described one by one.

[0057] In an embodiment, please refer to Figure 1 and Figure 2As shown, the application provides a hard disk active heat dissipation intensity control method 100, which specifically comprises:

[0058] Step 101, evaluating the current period business pressure of the hard disk to obtain a current period business pressure coefficient;

[0059] Step 102, predicting a first temperature change value based on the current period business pressure coefficient of the hard disk and a temperature coefficient of the hard disk;

[0060] Step 103, obtaining a plurality of actual temperature values measured by a plurality of temperature sensors of the hard disk, and calculating a composite temperature based on the plurality of actual temperature values and the temperature coefficient of each temperature sensor, and calculating a difference between the composite temperature and a preset target temperature to obtain a second temperature change value;

[0061] Step 104, calculating a next period temperature change value based on the first temperature change value, the second temperature change value, the current period business pressure coefficient and a previous period business pressure coefficient;

The active heat dissipation is used to reduce the temperature in the running process of the solid state disk while ensuring that the hard disk runs in a better state.

[0064] In some embodiments, the aforementioned step 101, evaluating the current period business pressure of the hard disk to obtain a current period business pressure coefficient, comprises:

Preferably, in the specific implementation process, the influence of the read-write pressure exchanged between the hard disk and the host on the temperature is greater than that of the service pressure of the hard disk itself on the temperature, and therefore the values of c1 and c2 can refer to the following strategy: the sum of the two is equal to 1, and c1 is greater than c2.

[0069] It should be noted that, although the current service pressure coefficient is not in a linear relationship with the above parameters A and B in practice, formula one only gives a way to quantify the current period service pressure coefficient, and other existing calculation methods of quantifying the current period service pressure can also replace the above formula one in the specific implementation process.

[0089] If the temperature change value in the next cycle falls within the preset range, the active heat dissipation intensity of the hard drive will continue to be maintained.

[0090] If the temperature change value in the next cycle exceeds the upper limit threshold, the active cooling intensity of the hard drive is increased.

[0091] If the next period temperature change value is less than the lower limit critical value, the active heat dissipation intensity of the hard disk is reduced.
