Fig. 1 is the schematic diagram of the heat abstractor of one embodiment of the invention.Please refer to Fig. 1, heat abstractor 100 is applicable to the main frame of server or computer system, heat abstractor 100 comprises at least one fan 102 (being in the present embodiment two, so not as limit), a temperature measurement unit 104, a fan control unit 106, a storage element 108 and a power attenuation control module 110.Its fan 102 couples fan control unit 106, and power attenuation control module 110 couples the power supply unit PSU of temperature measurement unit 104, fan control unit 106, storage element 108 and main frame.Wherein between power attenuation control module 110 and power supply unit PSU, carry out signal transmission for seeing through power management bus.
On the configurable air outlet in mainframe box of above-mentioned fan 102 or motherboard easily (for example, on central processor core) on overheated assembly.Fan control unit 106 is in order to control the rotating speed of fan 102, generally speaking, fan control unit 106 is for utilizing pulse width modulation signal to control, in the time that the responsibility cycle of pulse width modulation signal is larger, the rotating speed of fan is faster, and the power that relatively consumed is also higher.104 of temperature measurement units are in order to measure the temperature of main frame inside.
In addition, the electric energy that power attenuation control module 110 can provide according to power supply unit PSU carrys out the total power consumption of computation host, and send a control signal SC1 to fan 102 according to the total power consumption of main frame and the measured main frame internal temperature of temperature measurement unit 104, to determine that rotating speed how to control fan 102 adjusts the power attenuation of main frame, wherein controlling signal SC1 is a pulse width modulation signal.
For instance, in the time that power attenuation control module 110 judges that the total power consumption of main frame does not exceed default critical total power consumption, power attenuation control module 110 adjusts according to the internal temperature of main frame and the power attenuation of CPU (central processing unit) the responsibility cycle of controlling signal SC1 simultaneously.Wherein the critical total power consumption of indication is main frame required minimum total power consumption under system stability state herein.
The responsibility cycle table of comparisons of the internal temperature of main frame, the power attenuation of CPU (central processing unit) and corresponding control signal SC1 is as follows shown in list 1:
