Description
Technical field
The utility model relates to a kind of car radiation parts, particularly a kind of fan for automobile radiators.
Background technique
In the heat radiation cooling system of automobile, automobile radiators is very important parts, it is by the mobile heat of taking away automobile generation of cooling liquid, reach the object of cooling, and fan usually all can be installed on radiator, to increase the Air Flow of spreader surface, thereby reach better cooling effect.At some, need high density to cover on the radiator of fan, conventionally can adopt the fan with two or more impellers to satisfy the demands, a plurality of impellers of this fan are arranged on framework, and control its rotating speed by a controller, but in the situation that controller is made mistakes, this fan can cannot be worked because all impellers all stop operating, not only affect the work of car radiation cooling system, and because cannot accurately judge the fault of controller or the fault of one of them motor, increased the difficulty of malfunction elimination, and the employing of the controller in tradition is the mode of resistance adjustment, make fan rotating speed when temperature is too low too fast, cause the waste of air quantity, increased the oil consumption of automobile.
Summary of the invention
For the deficiencies in the prior art, problem to be solved in the utility model is to provide a kind of more stable and speed governing bilobed wheel automobile radiators more accurately.
For this reason, the utility model is realized in the following way: a kind of bilobed wheel radiator fans, comprise framework, the first impeller, the second impeller, the first motor, the second motor and controller, described the first impeller is connected with the second motor with the first motor being arranged on framework respectively with the second impeller, it is characterized in that: described controller comprises the first controller and second controller, described the first controller is connected with the second motor with the first motor respectively with second controller, described the first controller and second controller all comprise driver, central processing unit (CPU), voltage stabilizing circuit module and rotational speed control module, described driver one end is connected with the second motor with the first motor, the other end is connected with the output terminal of central processing unit (CPU), the input end of described central processing unit (CPU) is connected with the output terminal of voltage stabilizing circuit module and rotational speed control module.
Described the first impeller has five fan blades, and described the second impeller has seven fan blades.
In the utility model, thereby by the first controller and two controllers of second controller, control respectively the rotating speed of the first motor and the second motor control the first impeller and the second impeller, in this setup situation that controller breaks down therein, another one impeller can work on, guarantee the normal work of car radiation cooling system, and controller and motor set-up mode one to one, also facilitated the investigation of fault, and the first controller and second controller have all adopted integrated drive, central processing unit (CPU), the Intelligent central integration module structure of voltage stabilizing circuit module and rotational speed control module, controller is more accurately put in place to the control of motor, make the rotating speed of impeller meet air quantity required under Current Temperatures, reach optimization rotating speed, reduced the fuel consumption of automobile, improved the comfort of automobile.
Accompanying drawing explanation
The utility model has following accompanying drawing:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the framework schematic diagram of the control mode of this practical first controller and second controller.
Embodiment
With reference to accompanying drawing, this bilobed wheel radiator fans, comprise framework 4, the first impeller 6, the second impeller 1, the first motor 7, the second motor 3 and controller, described the first impeller 6 is connected with the second motor 3 with the first motor 7 being arranged on framework 3 respectively with the second impeller 1, described controller comprises the first controller 5 and second controller 2, described the first controller 5 is connected with the second motor 3 with the first motor 7 respectively with second controller 2, described the first controller 5 and second controller 2 all comprise driver, central processing unit (CPU), voltage stabilizing circuit module and rotational speed control module, described driver one end is connected with the second motor 3 with the first motor 7, the other end is connected with the output terminal of central processing unit (CPU), the input end of described central processing unit (CPU) is connected with the output terminal of voltage stabilizing circuit module and rotational speed control module, described the first impeller 7 has five fan blades, described the second impeller 1 has seven fan blades.This fan is arranged on automobile radiators by framework 4, and the input end of voltage stabilizing circuit module and rotational speed control module is connected with the sensor in car radiation cooling system, in car running process, sensor is given the first controller and second controller by real time temperature data transmission, temperature data is after entering the first controller and second controller, rotational speed control module sends the adjustment signal to motor speed according to Current Temperatures to central processing unit (CPU), voltage stabilizing short block guarantees that the signal that rotational speed control module sends to central processing unit (CPU) keeps stable, can not be subject to extraneous factor disturbs, the motor speed adjustment signal that enters central processing unit (CPU) just acts on driver after treatment, make driver change the rotating speed of the first motor 7 and the second motor 3 and change the rotating speed of the first impeller 6 and the second impeller 1, make it reach the optimization rotating speed matching with current temperature, the less waste of wind-force, reduce the oil consumption of automobile, and five blades that arrange on the first impeller 7 are less than seven blades that arrange on the second impeller 1, when this makes the first motor 7 and the second motor 3 drive the first impeller 6 and the second impeller 1 with identical rotating speed, the second impeller 1 can produce larger air quantity, this just makes wind in spreader surface, from the first impeller 6, to flow to the second impeller 1 place, having strengthened the plane of air in spreader surface flows, the perpendicular flow that air is produced in spreader surface in conjunction with the first impeller 6 and the second impeller 1 rotate, can reach better radiating effect.
