Abstract
The invention discloses a kind of temperature controller for being used to control electric fan wind speed, including NTC thermistor, the NTC thermistor is electrically connected with power supply and fan power interface respectively, and the fan power interface is arranged on electric fan, and fan power interface is electrically connected with electric fan.The present invention can carry out rotational speed regulation, the cost of the whole temperature controller substantially reduced to the DC fan without PWM speed-regulating functions.And the temperature controller is constituted by simple electronic component is simulated, and antijamming capability is greatly reinforced, with very strong reliability.Further, since its is simple in construction, production is not only convenient for, and cost is very cheap suitable for being widely popularized.
Description
Technical field
The invention belongs to temperature control technology field, and in particular to a kind of temperature controller for being used to control electric fan wind speed.
Background technology
The temperature control speed governing governing system of current fan after temperature sensor signal is received, is passed through mostly using master control IC
Regulation master control IC pwm signal exports to control the rotating speed of fan.Such systematic comparison is complicated, and requires that fan has PWM
Speed-regulating function, therefore the cost of this system is higher, and when master control IC is by external disturbance（Such as electrostatic impact, temperature
Cross high）Easily there is abnormal state in master control IC, so the state of fan can be caused not right, therefore the reliability of whole system
It is quite poor.
Moreover, circuit is all the rotating speed for controlling fan with temperature control by complicated electronic component realization at present, temperature is high,
Rotation speed of the fan is high, and the low rotation speed of the fan of temperature is low.
The content of the invention
It is an object of the invention to provide a kind of temperature controller for being used to control electric fan wind speed, to solve above-mentioned background technology
The problem of middle proposition.
To achieve the above object, the present invention provides following technical scheme：A kind of temperature control for being used to control electric fan wind speed
Device, including NTC thermistor, the NTC thermistor are electrically connected with power supply and fan power interface respectively, the electric wind
Power interface is fanned to be arranged on electric fan, and fan power interface is electrically connected with electric fan.
It is preferred that, the model NTC100D-9 of the NTC thermistor.
It is preferred that, the NTC thermistor is a kind of thermistor, the rise that its resistance is varied with temperature and
Reduction, this thermistor is the metal oxide by two kinds or four kinds of iron, nickel, cobalt, manganese or copper through overmolding and in high temperature
It is lower sintering and be made.
It is preferred that, the output voltage of the power supply is+12V.
The technique effect and advantage of the present invention：This is used for the temperature controller for controlling electric fan wind speed, compared with conventional art, this
Invention can carry out rotational speed regulation, the cost of the whole temperature controller substantially reduced to the DC fan without PWM speed-regulating functions.
And the temperature controller is constituted by simple electronic component is simulated, and antijamming capability is greatly reinforced, with very strong reliability.Separately
Outside, because its is simple in construction, production is not only convenient for, and cost is very cheap suitable for being widely popularized.
Existing electric fan controls the rotating speed of fan, the high wind of temperature by complicated electronic component and circuit realiration with temperature control
Fan rotating speed high, the low rotation speed of the fan of temperature is low, and the present invention is connected in fan circuit by thermistor, temperature is low
When resistance it is very big, rotation speed of the fan step-down, resistance step-down when temperature is high, temperature more high value is lower, and the rotating speed of fan will be with
The change of temperature and change, play fan speed purpose temperature controlled.
Brief description of the drawings
Fig. 1 is circuit theory module connection figure of the invention；
Fig. 2 is operating circuit schematic diagram of the invention.
Fig. 3 is the electric property table of the NTC thermistor of table 1 of the present invention.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
The invention provides a kind of temperature controller for being used to control electric fan wind speed as Figure 1-3, including NTC temperature-sensitives electricity
Resistance, the NTC thermistor is electrically connected with power supply and fan power interface respectively, and the fan power interface is arranged on
On electric fan, and fan power interface is electrically connected with electric fan, the model NTC100D-9 of the NTC thermistor, institute
It is a kind of thermistor to state NTC thermistor, the rise that its resistance is varied with temperature and reduce, this thermistor
It is to be sintered through overmolding and at high temperature and be made by the metal oxide of two kinds or four kinds of iron, nickel, cobalt, manganese or copper, it is described
The output voltage of power supply is+12V.
NTC thermistor string of the invention with a special negative temperature coefficient is in fan circuit, resistance when temperature is low
Very big, rotation speed of the fan step-down, resistance step-down when temperature is high, temperature more high value is lower, and the rotating speed of such fan will be with temperature
The change of degree and change, play fan speed purpose temperature controlled.
Finally it should be noted that：The preferred embodiments of the present invention are the foregoing is only, are not intended to limit the invention,
Although the present invention is described in detail with reference to the foregoing embodiments, for those skilled in the art, it still may be used
To be modified to the technical scheme described in foregoing embodiments, or equivalent substitution is carried out to which part technical characteristic,
Within the spirit and principles of the invention, any modification, equivalent substitution and improvements made etc., should be included in the present invention's
