Description
Technical field
The utility model belongs to the technical field of motor car engine, and in particular, the utility model relates to a kind of Motronic control maps fan control system.
Background technique
In prior art, the cool electronic fan of motor is generally realized the height speed control system of fan by two high power relays.Only have two fixed rotating speeds, energy loss is larger; Fan electromotor does not only have the short-circuit protection of fus, not the protective function such as overload, stall, overvoltage, under-voltage, temperature; Relay is in the electrical appliance kit of cabin, and the wire harness to fan is relatively long.
Model utility content
In order to solve above-mentioned technical problem of the prior art, the purpose of this utility model is to provide a kind of Motronic control maps fan control system.
To achieve these goals, the utility model have employed following technological scheme:
A kind of Motronic control maps fan control system, comprises PWM controller, it is characterized in that: the input end of described PWM controller is connected with the pressure transducer of air condition compressor, engine rotation speed sensor, intake air temperature sensor and cooling-water temperature transmitter; The output terminal of described PWM controller is connected with air conditioner electric magnet clutch, water pump and cool electronic fan.
Compared with prior art, Motronic control maps fan control system described in the utility model has following beneficial effect:
Motronic control maps fan control system of the present utility model realizes the low-loss of cool electronic fan energy, and control feedback real-time can realize the refrigerating function to vehicle engine system and air-conditioning system; It is applied to various types of vehicle, and the service behaviour of motor can be made to improve, and increases power character and the Economy of motor, extends the life-span of motor.
Accompanying drawing explanation
Fig. 1 is the structural representation of the Motronic control maps fan control system of embodiment 1.
Embodiment
Be further elaborated Motronic control maps fan control system described in the utility model below with reference to specific embodiment, to help, those skilled in the art conceives model utility of the present utility model, technological scheme has more complete, accurate and deep understanding.
Embodiment 1
As shown in Figure 1, Motronic control maps fan control system described in the present embodiment, comprise PWM controller, it is characterized in that: the input end of described PWM controller is connected with the pressure transducer of air condition compressor, engine rotation speed sensor, intake air temperature sensor and cooling-water temperature transmitter; The output terminal of described PWM controller is connected with air conditioner electric magnet clutch, water pump and cool electronic fan; When the pressure of described pressure transducer exceedes prescribed limits, PWM controller controls described air conditioner electric magnet clutch and disconnects, and air condition compressor quits work, and cool electronic fan carries out work; Described PWM controller detects engine rotation speed sensor, intake air temperature sensor, cooling-water temperature transmitter, and generates control signal and control cooling waterpump and cool electronic fan.
In the present embodiment, to realize content as follows in cool electronic fan control:
1. cool electronic fan adopts PWM pulse width modulation controlled, and replace relay by power MOS pipe, can realize rotating speed stepless time adjustment within the specific limits, efficiency is higher; Reliability and durability also improve greatly;
2. electronic fan controller is independent is arranged near cooling fan nearby, can reduce the length of wire harness, and heat radiation is also relatively good;
3. sample the signal such as pressure of the temperature of cooling liquid, intake temperature, engine speed, air condition compressor, control the rotating speed of electronic fan in real time, response is fast, can realize closed loop control;
4. electronic fan has the protective functions such as short circuit, overload, stall, overvoltage, under-voltage, temperature.
In the present embodiment, it uses the cool electronic fan of PWM pulse width modulation controlled, and speed is no longer single fixing rotating speed, but carries out stepless time adjustment by input signals such as sampling water temperature, motor, air-conditionings, and efficiency, reliability, real-time all improve; The antijamming capability of control system is also strengthened.Do not have anything to affect on complete vehicle weight, cost increases to some extent, but is significantly increased in environmental protection, energy-saving and cost-reducing, high-performance, intelligentized control method.
For the ordinary skill in the art; specific embodiment is just exemplarily described the utility model; obvious the utility model specific implementation is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present utility model is conceived and technological scheme is carried out; or design of the present utility model and technological scheme directly applied to other occasion, all within protection domain of the present utility model without to improve.
