Description
Technical field
The relevant a kind of fan operating control system of the present invention is meant a kind of controlling fan especially in an initial startup during stage, reduces the fan operating control system of the noise that its running sent.
Background technique
In general electronic equipment, in order to improve its operational paradigm, major part all can be installed radiation system, so as to reducing the high temperature that is produced when the electronic equipment inner member operates, to promote whole operational effectiveness.Particularly at computer apparatus, in order effectively to increase the operational paradigm of each electronic component, major part all can be installed fan and radiating subassembly.Wherein, the heat energy that radiating subassembly is produced when normally utilizing heat conducting mode directly to absorb the electronic component running, then, utilize the running of fan again and produce the convection current air, so as to heat energy that radiating subassembly absorbed by the heat exchange of convection current air loss to extraneous.
For example: in existing computer system, when start just, starting the required electric power of fan running is normally directly provided by power supply unit, at basic input output system (BasicInput/Output System; BIOS) finish after startup and the initializing set, just can begin the electric power of monitoring power supply supply fan running.Yet,, make fan will produce high noisy down running up at the beginning because the power supply unit commonly used most likely sends the electric power of a bigger operating voltage (being generally 12 volts).
See also Fig. 1, it is to show the existing fan running control circuit Block Diagram that applies to computer system.As shown in the figure, an existing fan operating control system 1 that applies to computer system comprises a power supply 11, a fan circuit assembly 12 and a monitoring unit 13.
When computer system was in an initial startup stage (being firm start-up phase), the required electric power of fan running must be relied on the rated electrical that power supply 11 sent and directly supply.Because the voltage of described rated electrical turns round with high rotational speed so can order about fan usually up to 12 volts, and produce bigger running noise.Simultaneously, in the operation process to fan, monitoring unit 13 is constantly monitored the running of fan, and sends described control signal S1 to fan circuit assembly 12.Yet, in the actual operation process, must go through a stabilization time usually after, the control signal S1 that monitoring unit 13 is sent could control fan with the running of lower stabilized speed, and the noise that is sent when reducing fan running.
Summary of the invention
Technical problem and purpose that institute of the present invention desire solves:
Take a broad view of in above-described prior art, because in initial startup during the stage, fan running can produce higher noise, must go through described stabilization time after, could control fan with the running of lower stabilized speed, and the noise that is sent when reducing fan running.
Therefore, main purpose of the present invention provides a kind of fan operating control system with in initial startup during the stage, described fan operating control system can downgrade into control electric power with the rated electrical that power supply provided earlier, utilizes control electric power to drive a fan with lower revolution running again.
Of the present invention time a purpose provides a kind of fan operating control system,, to be to utilize control electric power to drive a fan running, and can to utilize a power controlling signal to control described control electric power continuously simultaneously during the stage in initial startup.
The technological means that the present invention deals with problems:
The present invention provides a kind of fan operating control system for solving the technological means that prior art problems adopted, and it comprises a power supply, a control switch circuit, a switch controlling signal transmitting element and a fan circuit assembly.Power supply sends out a rated electrical; The control switch circuit is electrically connected on power supply; The switch controlling signal transmitting element is electrically connected on the control switch circuit, and sends a power controlling signal to the control switch circuit; The fan circuit electrical component is connected in the control switch circuit.The rated electrical that power supply sent out is resent to the fan circuit assembly and orders about the interior at least one fan running of fan circuit assembly after can coming down to a control electric power by the control switch circuit earlier.Send power controlling signal to the control switch circuit at the switch controlling signal transmitting element, utilize the power controlling signal regulation and control to come described control electric power.
The present invention has following advantage compared to prior art:
Compared to prior art, owing to after fan operating control system provided by the present invention downgrades rated electrical control electric power earlier, utilize control electric power to come the drive fan running again.Therefore, in initial startup during the stage, can't be higher because of voltage rating, and cause fan to produce bigger noise in the running.
Simultaneously, because the switch controlling signal transmitting element can constantly send power controlling signal, therefore, no matter be during the stage or in initial startup after the stage in initial startup, the effectively described electric power control of control all continuously, and and then guarantee that fan can not produce noise suddenly in any moment with high rotation speed operation.
