Step S116, determining a difference value between the first temperature value and the second temperature value, step S118, determining whether the difference value is greater than a preset value, generating a third determination result, if the third determination result is yes, performing step S120, adjusting the fan 50 to a high rotation speed state, until the third determination result is no, performing step S122, and operating the fan 50 in a low rotation speed state.
In the present embodiment, step S102, the fan 50 is operated at a low rotation speed; step S104, acquiring a first temperature value of the air temperature in the cabinet body 10 through a first temperature sensor; step S106, acquiring a second temperature value of an internal device of the cabinet body 10 through a second temperature sensor; step S108, determining whether the first temperature value meets a first preset condition, generating a first determination result, and if so, adjusting the fan 50 to a high-speed state by performing step S110, so as to enhance the flow of air in the cabinet body 10, enhance the heat exchange between the air and the internal devices, and further facilitate the rapid cooling of the internal devices.
When the first determination result is negative, step S112 is executed to determine whether the second temperature value satisfies a second preset condition, and a second determination result is generated, and when the second determination result is positive, the temperature of the air in the cabinet is too high, which is not convenient for heat dissipation of internal devices, and step S110 is executed to adjust the fan 50 to a high-speed state, so as to reduce the temperature of the air in the cabinet.
Until the second determination result is negative, the temperature of the internal devices and the air in the cabinet is not higher than the set value, and step S114 is executed to operate the fan 50 at a low rotation speed. Thereby, the power consumption of the cabinet can be reduced, and the fan 50 operates with less noise.
Step S116, determining a difference value between the first temperature value and the second temperature value, step S118, determining whether the difference value is greater than a preset value, generating a third determination result, if the third determination result is yes, performing step S120, adjusting the fan 50 to a high rotation speed state, until the third determination result is no, performing step S122, and operating the fan 50 in a low rotation speed state.
And when the third judgment result is yes, the temperature of the air in the cabinet is too high or the temperature of the internal devices is higher than the temperature of the air in the cabinet.
When the air temperature in the cabinet is too high, namely the ambient temperature of the internal device rises, the fan 50 is adjusted to be in a high-rotating-speed state, even if the ambient temperature of the device rises, the ambient temperature of the device is not high, active heat dissipation can be performed on the ambient environment of the device, the ambient environment is prevented from influencing the device, the heat dissipation process of the device is actually corrected, and the situations that the temperature of the device is low and the ambient temperature is high are avoided.
When the temperature of inside device is higher than the air temperature in the rack, adjust 50 high rotational speed states of fan, can strengthen the flow of the interior air of rack body 10 on the one hand, strengthen the heat transfer of air and inside device, on the other hand can reduce the temperature of the interior air of rack body 10, is convenient for improve the heat transfer speed of air and inside device.
