Abstract
The utility model discloses a rotating speed control system of an automobile engine cooling fan. The rotating speed control system is mainly characterized by comprising an engine, a temperature sensor, a fan control circuit, a fan rotating speed control system and a fan, wherein the temperature sensor is attached on the pipe wall of cooling water of the engine, and sends temperature information of the cooling water of the engine to the fan control circuit; and the fan control circuit analyzes and processes the temperature information sent from the temperature sensor. The rotating speed control system can improve the utilization efficiency of the engine, lead the engine to work under the optimum temperature, and play roles of reducing the noise of the engine and reducing the emission of harmful substances in the tail gas, and can be used in the fields of automobile manufacture and scientific research and the like.
Description
Technical field
The utility model relates to a kind of revolution speed control system of automobile engine cooling fan, belongs to the Vehicle Electronic Control field.
Background technique
Usually all be equipped with the cooling fan that rotates with motor in the existing automobile, be used for wind cooling temperature lowering is carried out in the engine cooling water loop.
In the practice, the water temperature excursion of cooling water is uncontrollable, may exist water temperature overheated, and water temperature is normal, three kinds of states that water temperature is cold excessively.Just need the fan high speed rotating reducing water temperature for the water temperature superheat state, for water temperature normal state and water temperature supercooled state cooling fan can low speed and extremely low rotating speed rotate so that motor is in optimum Working.
Yet in the prior art, no matter the temperature of cooling water is in any state, and entire car controller can't be adjusted rotating speed of motor along with the variation of water temperature, can only be that fan work is under high speed.Even the rotating speed that can regulate fan according to the variation of water temperature that has, be that water temperature fan when low excessively stops operating, fan need consume big energy by the moment that does not forward rotation to when water temperature is high like this, will waste energy consumption, the unnecessary motor rotational noise of increase of automobile like this, motor is not operated in the optimum temperature range, also can increase exhaust of some harmful pollutants.
Summary of the invention
In view of this, the utility model provides a kind of revolution speed control system of automobile engine cooling fan, can save the energy consumption of automobile, be that motor car engine is operated in the optimum temperature range, and reduce unnecessary motor rotational noise and reduce content of harmful in the tail gas.
The utility model provides a kind of revolution speed control system of automobile engine cooling fan, comprises motor, temperature transducer, fan control circuitry, fan rotary speed control system, cooling fan, and described temperature transducer is positioned on the tube wall of engine cooling water pipe; Described circuit for controlling speed of fan links to each other with temperature transducer; Described fan rotary speed control system links to each other with cooling fan by fan control circuitry; Between described motor and the fan rotary speed control system cooling fan is installed.
The utility model is the advantage of prior art relatively:
(1) the utility model adopts the temperature of temperature transducer perception engine cooling water, utilize the Electric Machine Control speed of cooling fan, under can only being operated at a high speed, the most existing cooling fan can make engine operation in optimum temperature range, reduce energy consumption, reduced content of harmful in the tail gas.
(2) the utility model is crossed in water temperature and is made fan with extremely low rotational speed under the cold situation, than existing sub-fraction adopt water temperature cross under the cold situation fan stop operating can avoid fan when water temperature is too high by the high energy consumption that does not forward rotation to, saved resource.
Description of drawings
Fig. 1 is that the revolution speed control system of automobile engine cooling fan described in the utility model is arranged schematic representation.
Embodiment
The 1-motor; The 2-temperature transducer; The 3-fan control circuitry; The 4-fan rotary speed control system; The 5-fan.
Below in conjunction with embodiment's accompanying drawing the utility model is described further.
As shown in Figure 1, the revolution speed control system of automobile engine cooling fan described in the utility model comprises motor 1, temperature transducer 2, fan control circuitry 3, fan rotary speed control system 4 and fan 5.Described temperature transducer 2 is installed on the tube wall of engine cooling water, the temperature of perception cooling water at any time, and temperature signal passed to fan control circuitry timely; Described fan control circuitry 3 receives the cooling water temperature signal that temperature transducers transmit, and temperature signal is converted to electrical signal passes to fan rotary speed control system; Described fan rotary speed control system 4 receives the electrical signal that fan control circuitry transmits, the rotation of control fan, coolant water temperature is spent and is controlled fan when hanging down with extremely low rotational speed, and the control fan slowly ran when cooling water was 85 °-95 °, control fan high speed rotating when cooling water temperature is too high.Under optimum temperature, work the efficient of raising motor to realize motor.
The above is preferred embodiment of the present utility model only, is not to be used to limit protection domain of the present utility model.All within spirit of the present utility model and principle, any modification of being done, be equal to and replace and improve, all should be included within the protection domain of the present utility model.
