Deng, it is of the invention that a kind of data center's water cooling unit cabinet PWM control methods are provided based on this, with reference to fan feature, controlled using PWM
Mode realizes accurate air-supply.
The content of the invention
The technical assignment of the present invention is that there is provided a kind of data center's water cooling unit cabinet PWM controlling parties for above weak point
Method.
A kind of data center's water cooling unit cabinet PWM control methods, its implementation process is：Obtain water-cooled cabinet first enters wind-warm syndrome
Degree, the inlet air temperatures are then sent to BMC, by BMC send pwm control signal to regulation fan, the control signal based on
Lower four kinds of range restraint fans：When inlet air temperatures are less than 15 DEG C, between 15 DEG C to 26 DEG C, more than 26 DEG C and no more than 35
DEG C when, more than 35 DEG C when, fan is respectively adopted four kinds of different rotating speeds and carries out temperature adjustments, and four kinds of different rotating speeds orders rise
It is high.
When inlet air temperatures are less than 15 °, the rotating speed that fan is kept is 1300rpm；
When inlet air temperatures are more than 26 DEG C and no more than 35 DEG C, the rotating speed that fan is kept is 2100rpm；
Corresponding, when inlet air temperatures are between 15 DEG C to 26 DEG C, the rotating speed that fan is kept is 1300~2100rpm；
When inlet air temperatures are more than 35 °, fan running rotating speed brings up to 2500rpm.
When BMC non-mandrel rollers or water-cooled cabinet initial power-on, rotation speed of the fan is opened to 100%, i.e. initial value.
Regulation fan in the water-cooled cabinet is the radiator fan group being made up of some fans, when single regulation fan does not have
When having signal feedback, other all fans are adjusted to 2400rpm, and no signal feedback here refers to that fan is extracted, fan is damaged
Bad situation.
10V pwm control signals are converted to after the PWM chip output, regulation fan is then directly direct by 220V alternating currents
Power supply, PWM chip control 10V DC PWM rotating speeds, and in PWM duty cycle>15% fan, which is opened, to be turned, PWM duty cycle<5% fan stops
Turn.
When adjust fan pwm signal dutycycle between 15% ~ 100% when, BMC output PWM control signal duty cycle with
Corresponding relation between rotating speed V is：X=15+（V-550）*17/490.
The present invention a kind of data center's water cooling unit cabinet PWM control methods compared to the prior art, with following beneficial effect
Really：
A kind of data center's water cooling unit cabinet PWM control methods of the present invention, realizing the fan control of water-cooled cabinet, there is provided accurately
The specific rotating speed control provided in temperature control, and this method is the optimum speed drawn in practical operation, meets server
Use demand, improve radiating efficiency, it is practical, it is applied widely, it is easy to promote.
