Embodiment
Fig. 1 is the synoptic diagram of the heat abstractor of one embodiment of the invention.Please with reference 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 two in the present embodiment, 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 carry out the signal transmission for seeing through the power management bus between power attenuation control module 110 and the power supply unit PSU.
Be prone to (for example on the central processing unit chip) on the overheated assembly on configurable air outlet or the motherboard in mainframe box of above-mentioned fan 102.Fan control unit 106 is in order to the rotating speed of control fan 102; Generally speaking, fan control unit 106 is controlled for utilizing the pulse width modulation signal, when the responsibility cycle of pulse width modulation signal is big more; The rotating speed of fan is fast more, and the power that is relatively consumed is also high more.104 of temperature measurement units are in order to the measurement host temperature inside.
In addition; Power attenuation control module 110 can come the total power consumption of computation host according to the electric energy that power supply unit PSU is provided; And send a controlling signal SC1 to fan 102 according to the total power consumption and the temperature measurement unit 104 measured main frame internal temperatures of main frame; Rotating speed how to control fan 102 with decision is adjusted the power attenuation of main frame, and wherein controlling signal SC1 is a pulse width modulation signal.
For instance; When power attenuation control module 110 judged that the total power consumption of main frames does not exceed preset critical total power consumption, power attenuation control module 110 was adjusted the responsibility cycle of controlling signal SC1 simultaneously according to the power attenuation of the internal temperature of main frame and CPU.Wherein the critical total power consumption of indication is main frame required minimum total power consumption under the system stability state here.
The responsibility cycle table of comparisons of the internal temperature of main frame, the power attenuation of CPU and corresponding controlling signal SC1 can be tabulated shown in 1 as follows:
| Internal temperature: 10 ℃ | Internal temperature: 15 ℃ |
