Abstract
The present utility model relates to a fan speed controller installed in the power supply of personal computers to switch the control mode of the cooling fan supplied by the power supply. It is characterized by that there is a fan speed controller between the circuit of the power supply and the cooling fan, which includes a knob controller,a control circuit and several indicating lamps, so the control mode of said cooling fan can be switched by the knob controller so as to control the activation and the rotating speed of the cooling fan manually or automatically.
Description
Technical field
The utility model relates to a kind of rotation speed of the fan controller structure, particularly a kind of activation that is used for being controlled at the radiation fan of PC computer main power supply unit inside, and optionally adjust the controller structure of the rotating speed of radiation fan with manually or automatic control.
Background technique
The power supply unit that the PC computer is used is seen in general market, all be equiped with power circuit and one or two radiation fans that transformation and voltage stabilizing are used in a housing, the central processing unit (CPU) (CPU), adapter, magnetic disk driver (containing soft, Winchester disk drive, CD-ROM drive or the like) and the relevant extension facility thereof that are used for supplying with the PC computer-internal use; Yet, during this conventional power source supply running, its inner radiation fan all directly activates along with the unlatching of power circuit, no matter promptly whether too high its all can drive fan rotate the operating temperature of this power supply unit, and cause power supply waste when start just or long-term standby equitemperature are low, simultaneously, this radiation fan noise when rotated also can influence user or other people peacefulness always, so be necessary to be improved.
Summary of the invention
Main purpose of the present utility model is providing a kind of power supply unit internal heat dissipating fan employed rotation speed of the fan controller structure.
Above-mentioned purpose of the present utility model is achieved in that a kind of rotation speed of the fan controller structure, is installed in the power supply unit inside that the PC computer is used, and is used for switching the control mode of the radiation fan that is used by the power supply unit power taking, it is characterized in that:
Be connected with a rotation speed of the fan controller between the power circuit of power supply unit and radiation fan, this rotation speed of the fan controller includes a knob controlling device, control wiring and several tutorial light;
This knob controlling device is installed in appropriate location, the power supply unit frame back side, and it has " manually " and reach the switching alternative pack of " automatically " two sections, and two sections RCA is connected to the line contacts of the different pattern of control wiring respectively;
This control wiring comprises manual mode circuit and automatic mode circuit, and wherein the automatic mode circuit is provided with a temperature transducer;
These several tutorial light are installed in appropriate location, the power supply unit frame back side, and are connected to respectively between the RCA and control wiring of each section in the knob controlling device.
The utility model is when being used in combination, the activation of this radiation fan is to switch its control mode with the knob controlling device, as: not before the push-turn key controller, its green indicating lamp is shinny, the radiation fan system of expression power supply unit freely adjusts its rotating speed with hand rotation knob controlling device, and can adjust to the highest rotating speed by minimum rotating speed, the Environmental Conditions arround can cooperating is adjusted the rotating speed of radiation fan; In addition, behind the push-turn key controller, when its blue indicator light is bright, switch to automatic control mode immediately, it utilizes temperature sensor measurement power supply unit temperature inside, when its temperature rises to uniform temperature more than, fan just can slowly activate and dispel the heat, treat that its inside temperature drops to below the uniform temperature, radiation fan just can shut down automatically.
The utility model has the advantages that, both can manually control the rotating speed of radiation fan, also can activate the radiation fan running automatically, not only have certain radiating effect, also can reduce the effect of noise simultaneously along with operating temperature.
Below in conjunction with accompanying drawing the utility model is elaborated.
