Description
Technical field
The invention relates to a kind of radiating management device, particularly about a kind of radiating management device that is applied in a plurality of heat abstractors and this heat abstractor operation of a control.
Background technology
Along with the development of CPU, GPU technology, after computer-internal CPU and the increase of GPU frequency, its power consumption and thermal value are also along with improve, for cooling often requires to adopt more powerful powerful fan.But comparatively speaking, the rotating speed of fan is high more, and the noise of generation is also just big more.Therefore, the radiator fan in the cabinet (as the fan on cpu fan, video card fan, power supply fan and the cabinet etc.) has just formed the main noise source of computing machine.
Yet, if just constantly increase fan number and rotating speed, except above-mentioned noise problem, more can cause power wastage for the heat-sinking capability of system, also can reduce fan life simultaneously, cause system's operation costs to increase.Therefore, be generally the purpose that reaches the control rotation speed of the fan, detect the temperature of wind inlet of fan by the thermistor of fan spindle bearing, CPU work the time can produce heat, and guide to heat radiator itself by heat radiator with the heat of CPU this moment, through fan the heat on the heat radiator dispelled again, therefore the heat on heat radiator is high more, the temperature that thermistor is sensed is just high more, and just can avoid cpu temperature too high with the high rotational speed operation this moment, but the method can't accurately be controlled the rotating speed of fan.
The method of another kind of control fan is exactly the linear voltage stabilization method.By the DC voltage of linear voltage regulator adjustment fan, just control fan by the DC voltage at control fan two ends.This method must apply specific voltage to fan before the fan entry into service, the so-called trigger voltage of this specific voltage, when fan in the running, stop below the voltage if drop to one for the magnitude of voltage of fan, can make fan shut down.Trigger voltage usually can be approximately 25%～50% of fan rated voltage more than or equal to stopping voltage, yet, when using the linear voltage stabilization method not do the speed monitoring, can't learn when fan can start and when can shut down.Address the above problem two kinds of ways are generally arranged, first kind is that the voltage of avoiding being applied to fan is lower than trigger voltage, though this can select correct voltage can both receive suitable trigger voltage to guarantee each fan by the mode of software control, if consider problem of aging, then can cause the restriction of speed control range.Second method then is to adopt velocity gauge, this velocity gauge can be monitored by micro controller, therefore can allow computer system know that fan has or not and start or stagnate,, but need longer design time and extra hardware and software cost though this way is more firm and can not waste.
The technology that comparatively generally adopts is with pulse-length modulation (PWM at present, Pulse WidthModulating) directly controls fan, refer to the on off state that adopts fixing frequency control fan power supply, output voltage can be supplied with pulse mode, be obtained required voltage and frequency by the mode that changes pulse width, quantity.The adjustment by effective duty cycle (Duty cycle) just is as the control of rotation speed of the fan, and effectively duty cycle is big more, and the rotating speed of fan is just fast more.For instance, the rotating speed that changes fan can reduce voltage, reduce voltage and can control voltage by variable resistor and fan is strengthened or weaken; Another kind of mode then is to change ON time, mode service voltage with outage and energising, such as so that 12V to be provided sometimes, sometimes provide the pattern of 0V to change the fan voltage conduction status, control the intensity that fan moves according to the length and the periodicity of ON time again, just can change the intensity of rotation speed of the fan, pulse-length modulation that Here it is as 10%～90% different time cycle.
The intrasystem system management chip that uses a computer carries out the control of fan in the mode of pulse-length modulation, and driving circuit is simple, starting characteristic good, and the transistor thermal value of Control current is minimum simultaneously; But its consumed power height, and be not easy to accomplish the control of precise speed, in addition, when fan breaks down, need personnel with manual eliminating, consumed time makes system temperature too high easily, causes the situation when machine, even the System on Chip/SoC damage, moreover, if reach the purpose of system monitoring, must use multiple logical circuit, cause cost too high.
Therefore, how to provide a kind of and utilize simple design and to reach the scheme of system monitoring purpose at different system state (as fan failure) balanced system temperature, real is present problem demanding prompt solution.
