Abstract
A fan comprises a controller, a switch, a storage battery, a fan motor and an interface. The controller comprises a storage, a timer and a control unit, wherein the storage is used for storing a preset timing valve, and the timer is used for timing the operation time of the fan motor after a computer system is shut down so as to lead the control unit to control the fan motor to stop operating when the preset timing value is due within the timing time. The controller is connected with the interface, the switch, the storage battery and the fan motor, and the switch is connected with the storage battery. The fan can still continue to rotate for a period after the computer system is powered off so as to actively dissipate heat remained in a computer case after shutdown, and therefore service life of the computer system can be prolonged.
Description
Technical field
The present invention relates to a kind of fan.
Background technology
Electronic equipment such as computer system are after system cut-off, and inner radiator fan stops operating owing to losing the power supply supply, and this moment, the heat of internal system remnants can only discharge by the passive heat radiation of cabinet.In the situation that environment temperature is higher around, this will cause the internal system temperature still higher within postboost a period of time, thereby shorten the serviceable life of computer system.
Summary of the invention
In view of this, be necessary to provide a kind of fan, behind system cut-off, still continue to rotate a period of time so that electronic equipment is dispelled the heat.
A kind of fan, comprise a controller, one switch, one accumulator, one fan motor and an interface, described controller comprises a storer, one timer and a control module, described storer is used for storage one default clocking value, described timer is used for after the computer system shutdown carrying out timing the working time of fan motor, described controller connects described interface, described switch, described accumulator and described fan motor, described switch connects described accumulator, described fan connects a mainboard by described interface, when described mainboard normal power supply, described control module receives voltage to described fan motor by described interface from described mainboard, thereby to control the operation of described fan motor work control fan; When described mainboard is not worked, described control module will can not receive voltage from described mainboard, described control module is controlled described switch conduction, thereby so that described accumulator provides voltage to described fan motor by described switch and described controller, thereby control described fan operation to control described fan motor work, simultaneously described timer begins timing and when timing arrives default clocking value, described control module is controlled described switch cut-off, so that described accumulator stops to provide voltage to described fan motor.
Compare prior art, described fan can still continue to rotate a period of time after the computer system outage, heat remaining in the rear cabinet that shuts down is carried out active heat removal, thereby can prolong the serviceable life of computer system.

Following embodiment further specifies the present invention in connection with above-mentioned accompanying drawing.
Embodiment
Please refer to Fig. 1, fan 100 preferred embodiments of the present invention comprise a controller 10, a switch 20, an accumulator 30, a fan motor 40 and an interface 50.In the present embodiment, only listed the part assembly of described fan 100, other assembly on the described fan 100 is identical with other assembly on the common fan, such as blade etc., does not repeat them here.Described controller 10 comprises a storer 11, a timer 12, a control module 13 and a charhing unit 14.Described storer 11 is used for storing saturation voltage value and a default clocking value of described accumulator 30.When the voltage that described charhing unit 14 is used for when computer system is worked and described control module 13 detects described accumulator 30 is lower than saturation voltage value described accumulator 30 is charged.Described timer 12 is used for after the computer system shutdown carrying out timing the working time of fan motor 40, when arriving the default clocking value in the described storer 11 at timing time so that the described fan motor 40 of control module 13 controls quit work.
Described controller 10 connects described interface 50, described switch 20, described accumulator 30 and described fan motor 40.Described switch 20 connects described accumulator 30.
During use, described fan 100 connects a computer main board 200 by its interface 50.When described mainboard 200 normal operation, described control module 13 receives voltage and exports to described fan motor 40 from described mainboard 200 by described interface 50, thereby with 100 operations of control fan motor 40 work control fans, simultaneously, described controller 10 is detected the voltage of described accumulator 30 and itself and the saturation voltage that is stored in the storer 11 is compared, if it is lower than saturation voltage, then described switch 20 conductings of described control module 13 controls, and charge for described accumulator 30 by described charhing unit 14, and when the voltage of described accumulator 30 arrives saturation voltage value, control described switch 20 cut-offs, to stop described accumulator 30 chargings.
When described mainboard 200 is not worked, described controller 10 will can not receive voltage from described mainboard 200, described switch 20 conductings of described control module 13 controls this moment, thereby so that described accumulator 30 provides voltage to described fan motor 40 by described switch 20 and described controller 10, thereby control described fan 100 operations with 40 work of control fan motor, simultaneously described timer 12 beginning timing and when timing arrives default clocking value, described switch 20 cut-offs of described control module 13 controls are so that described accumulator 30 stops to provide voltage to described fan motor 40.
Described fan 100 can still continue to rotate a period of time after the computer system outage, heat remaining in the rear cabinet that shuts down is carried out active heat removal, thereby can prolong the serviceable life of computer system.
