According to the conformation, the input terminal and the output terminal are respectively connected with the power source and the fan motor of the radiator fan. When the fan motor stops to rotate, the LED can blink, and the buzzer can send out the warning sound to warn the user that the radiator fan gets out of order. The power source can be closed at once, to avoid the product from being burnt for the radiator fan stopping operation and achieve the favorable effect of heat radiation.
Description
Technical field
This creation is relevant a kind of radiator fan inefficacy warning system, refers to that especially a kind of product of avoiding burns because of radiator fan shuts down, and reaches the warning system of keeping good heat radiating.
Background technology
Air-cooled cooling method is exactly our modal at ordinary times a kind of heat dissipating method, and a radiator fan adds a heat radiator and just constituted a cover wind-cooling heat dissipating device.Air-cooled cooling method is that present computer to dissipate heat uses at most, also is the most ripe method.Take your mainframe box apart, you can find its figure at CPU, display card and power supply unit or the like everywhere.Its principle is exactly to rotate by radiator fan in simple terms, strengthens air flow, utilizes the mode of forced convertion that the lip-deep heat of heat generating component is conducted to surrounding environment.
The employed radiator fan of air-cooled cooling method has certain serviceable life, because radiator fan is an assembly that constantly rotates, all can be rubbed and loss so drive the bearing and the carbon brush (collecting brush) of the fan motor inside of this radiator fan rotation; When the abrasion of bearing and carbon brush is excessive, the friction force of bearing is constantly increased, if this friction force surpasses the driving force of fan motor, this fan motor will shut down, and radiator fan is stopped operating.As long as this radiator fan one stops operating, utilize the lip-deep heat of heat generating component of this radiator fan heat radiation just can't conduct to surrounding environment smoothly, like this, will cause this heat generating component Yin Wendu too high and burn.
Summary of the invention
This case designer has the disappearance of stating known radiator fan structure in view of this, and the whence studies intensively, and long-pending individual is engaged in the many years of experience of this cause, designs a kind of brand-new radiator fan inefficacy warning system eventually.
The design's fundamental purpose aims to provide a kind of radiator fan inefficacy warning system, burns because of radiator fan shuts down to avoid product, reaches and keeps good heat radiation purpose.
For reaching above-mentioned purpose, the design's radiator fan inefficacy warning system mainly comprises a circuit board, it is characterized in that: this circuit board is provided with an input terminal, lead-out terminal, sensor circuit, control chip, oscillatory circuit, driving circuit, LED and hummer and is connected.
According to above-mentioned structure, the design's radiator fan inefficacy warning system input terminal wherein is connected with a power supply, and this lead-out terminal is connected with the fan motor of a radiator fan, when this radiator fan stopped operating, this LED is flicker constantly, and this hummer can send the caution sound, this radiator fan of warning user breaks down, should close switch power supply immediately and do trouble hunting, burn because of radiator fan shuts down, reach the effect of keeping good heat radiating to avoid product.

Embodiment
The design's structure, device and feature thereof are lifted a preferable possible embodiments and are cooperated graphic being described in detail as follows:
The Fig. 1, shown in Figure 3 that please arrange in pairs or groups, the design's radiator fan inefficacy warning system mainly comprises a circuit board 1, it is characterized in that:
The surface of this circuit board 1 is provided with an input terminal 10 and lead-out terminal 11, is provided with a sensor circuit 12 between this input terminal 10 and the lead-out terminal 11.
This sensor circuit 12 is connected with input terminal 10, lead-out terminal 11 and a control chip 13, and this sensor circuit 12 is exported an induced signal according to the variation of the electric current between input terminal 10 and the lead-out terminal 11.
This control chip 13 is connected with a sensor circuit 12 and an oscillatory circuit 14, and this control chip 13 receives the induced signal that sensor circuit 12 transmits and come, and exports a control signal according to the variation of this induced signal.
This oscillatory circuit 14 is connected with one drive circuit 15 and LED16, this oscillatory circuit 14 receives the control signal that control chip 13 transmits and come, when this oscillatory circuit 14 received control signal, this oscillatory circuit 14 was exported an oscillator signal continuously to driving circuit 15 and LED16.
This driving circuit 15 is connected with an oscillatory circuit 14 and a hummer 17, and this driving circuit 15 receives the oscillator signal that oscillatory circuit 14 transmits and come, and amplifies the electric current of this oscillator signal, and with the oscillator signal input hummer 17 after this electric current amplification.
Please refer to shown in Figure 2ly, the design's radiator fan inefficacy warning system input terminal 10 wherein is connected with a power supply 2, this lead-out terminal 11 is connected with the fan motor 30 of a radiator fan 3 again; The electric current that this power supply 2 is exported is entered by input terminal 10, and this electric current exports fan motor 30 by behind the sensor circuit 12 to by lead-out terminal 11, rotates to drive this fan motor 30, and this radiator fan 3 is rotated.
According to above-mentioned structure, when this creation radiator fan inefficacy warning system is broken down and is stopped operating at radiator fan 3 and fan motor 30, will interrupt through input terminal 10, sensor circuit 12 and lead-out terminal 11 this current return by power supply 2, therefore not have electric current by sensor circuit 12 to fan motor 30; This sensor circuit 12 detect do not have electric current to pass through after, it exports an induced signal to control chip 13, and this control chip 13 is exported one according to received induced signals and controlled signal to oscillatory circuit 14; After this oscillatory circuit 14 receives the control signal that control chip 13 transmits and come, this oscillatory circuit 14 produces an oscillator signal, and export this oscillator signal to driving circuit 15 and LED16 continuously: after this oscillator signal input LED16, this LED16 is constantly glimmered; And this driving circuit 15 is done amplification with the electric current of this oscillator signal after receiving the oscillator signal that oscillatory circuit 14 transmits and come, and with the oscillator signal input hummer 17 after this electric current amplification, makes this hummer 17 send the caution sound.
As mentioned above, only need utilize the design's radiator fan inefficacy warning system input terminal and lead-out terminal wherein,, can detect radiator fan and whether run well the design is serially connected with between the power circuit of radiator fan; And when this radiator fan shuts down, LED is constantly glimmered, and send the caution sound through hummer; So, by vision and stimulation acoustically, this radiator fan of warning user breaks down, and powered-down is done trouble hunting immediately, burns because of radiator fan shuts down to avoid product, reaches the effect of keeping good heat radiating.
In sum, the design's radiator fan inefficacy warning system can avoid product to burn because of radiator fan shuts down really, reaches the effect of keeping good heat radiating, and " practicality " of tool utility model and " progressive ".The application of novel patent is mentioned according to Patent Law in the applicant whence.
