Abstract
The utility model discloses a radiating fan used in electronic apparatus, electronic device and electrical device, in particular to an indication device of the operation state of the radiating fan. The utility model comprises a wind speed sensor arranged on the fan, which can output waning signal when the wind speed is lower than the setting value. The output end of the wind speed sensor can be connected to a host state control circuit that can stop the operation of the host according to the warning signal output by the sensor. Whether the host of the utility model is in normal operation state is wholly controlled by the output wind speed of the fan, and the fan can emit warning signal when a mechanical failure or lowering of rotation speed occurs, so as to timely stop the operation of the host and ensure that the host is operated under safe state.
Description
Technical field:
The utility model relates to the radiator fan that uses in electronic device, electronic equipment, the power equipment, especially the running status indicating device of radiator fan.
Background technology:
Critical piece in electronic device, electronic equipment, the power equipment at work can distribute heat, for preventing its critical piece because temperature is too high to be burnt out, must dispel the heat.Now the heat abstractor that generally adopts is a fan, and stall or rotating speed lower if fan breaks down, and must in time stop the main frame operation, in order to avoid main frame is impaired.The device of existing monitoring mode of operation of fan is: as shown in Figure 1, in electric control loop, utilize the mode of auxiliary switch contact, whether the testing circuit loop is normal, if the loop is normal, existing monitoring device thinks that promptly fan is normal and indicate main equipment to work on.But in real work, can not get rid of the normal and fan in loop because the possibility that mechanical fault stall or rotating speed reduce, at this moment monitoring device can not normally reflect the working condition of fan, fan cisco unity malfunction and major equipment still in operation, the situation that causes the temperature rising excessively to burn out main equipment often occurs, not only cause damage economically, also might cause security incident.
The utility model content:
The purpose of this utility model provides a kind of running status indicating device of radiator fan of the running status that can correctly reflect the radiator fan that uses in electronics, the power equipment.
The running status indicating device of radiator fan of the present utility model comprises the air velocity transducer that is arranged on the fan, when wind speed during less than setting value, and the sensor output alarm signal.
Because the running status indicating device of radiator fan of the present utility model comprises the air velocity transducer that is arranged on the fan, when wind speed during less than setting value, the sensor output alarm signal.The output terminal of air velocity transducer can connect the Host Status control circuit, and the Host Status control circuit can stop the operation of main frame according to the alerting signal of sensor output.Whether use main frame of the present utility model keeps normal operation to be controlled by the output wind speed size of fan fully, when fan runs into mechanical fault stall or rotating speed reduction, can send alerting signal, in time be stopped the main frame operation, guarantee that main frame moves under safe condition.
Description of drawings:
Fig. 1 is the principle of work synoptic diagram of existing cooling fan indicator;
Fig. 2 and Fig. 3 are principle of work synoptic diagram of the present utility model.
Embodiment:
Embodiment 1
As shown in Figure 2: described air velocity transducer is set to: at the fan shaft rear back-moving spring 1 is set, and be provided with near switch 2 at the rotating shaft rear, when fan runs well, fan moves backward, close near switch, near switch open, normally move with the Host Status control circuit indication main frame that is connected near switch.When fan stall or rotating speed reduction, under the effect of back-moving spring 1, fan travels forward, and away near switch, closes near switch, and is out of service with the Host Status control circuit indication main frame that is connected near switch.
Or will be arranged on rotating shaft the place ahead near switch, when fan ran well, fan moved backward, away near switch, closed near switch, normally moved with the Host Status control circuit indication main frame that is connected near switch.When fan stall or rotating speed reduction, under the effect of back-moving spring, fan travels forward, and is near near switch, near switch open, out of service with the Host Status control circuit indication main frame that is connected near switch.
As shown in Figure 3: back-moving spring is torsion spring also, be arranged on the fan base 3, this fan base 3 is rotatable, and rotating shaft 4 departs from mutually with fan shaft 5, before or after the fan page or leaf 6 of pedestal one side, be provided with near switch 2, connect the Host Status control circuit near switch 2, when fan runs well, because pedestal rotating shaft both sides are subjected to force unbalance, pedestal deflection, the fan page or leaf of this side departs from backward, change with distance near switch, send fan normal operation signal near switch this moment, when fan stall or rotating speed reduction, under the effect of torsion spring, pedestal resets, fan page or leaf and range recovery near switch send the fan running anomalous signals near switch, and indication Host Status control circuit stops main frame and moves.
Described air velocity transducer is set to: one of them or several fan page or leaf of fan are adopted a lighter or heavier material, when fan stall or rotating speed are lower than setting value, heavier fan page or leaf hangs down naturally, at the fan page or leaf position of hanging down sensor is set, when the time that the fan page or leaf hangs down was higher than setting value, the Host Status control circuit indication main frame that is connected with sensor was out of service.
Described air velocity transducer is air pressure probe also, is arranged on before the fan or behind the fan, when air pressure surpasses the value of setting, and the sensor output alarm signal, main frame running status control circuit stops the operation of main frame in view of the above.
It is the radiator fan run indicator that is used to make the generator static excitation equipment that typical case of the present utility model uses.The applicant has produced model machine, and result of use is good.
