Abstract
The utility model discloses a circuit structure of an automobile air conditioner draught fan. The circuit structure is characterized in that the two ends of the air conditioner draught fan are connected to a connector respectively through an inductor L1 and an inductor L2; the two ends of the air conditioner draught fan are connected with a capacitor C4 and a capacitor C5 and then are connected to the ground, and a capacitor C1, a capacitor C2 and a capacitor C3 are connected in series and then are connected to the ground. By means of the circuit structure, the automobile air conditioner draught fan has the advantages that the electromagnetic compatibility of the draught fan which has no electromagnetic compatibility or has the electromagnetic compatibility but does not meet the requirement can be effectively improved; the operation is easy, and the technique is convenient to achieve.
Description
Technical field
The utility model relates to the air conditioning for automobiles field, particularly a kind of circuit structure of car air-conditioner blower fan.
Background technology
Along with the raising of expanding economy and living standards of the people, automobile has entered huge numbers of families, and automotive electronic technology is also more and more ripe.But electromagnetic interference has a strong impact on the normal operation of various electronic components in automobile, brings potential safety hazard.
In order to prevent electromagnetic environment, disturb the performance to automobile electronics to have a negative impact, avoid the forfeiture of automobile electronics function, guarantee that a large amount of vehicle electronicies can be each other without impact reliable operation in same electric system, just must determine a suitable interference limit, to guarantee between electromagnetic interference (EMI) emissions and the electromagnetic susceptibilty limit to exist enough safe capacity restrictions.Become an important topic so solve the electromagnetic compatibility of automotive electrical system.
The car air-conditioner blower fan is as the high-power electric appliance of indoor minority, and how actv. is controlled and improves its electromagnetic compatibility, is still a difficult problem for prior art.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of circuit structure of car air-conditioner blower fan, to realize improving the purpose of car air-conditioner blower fan electromagnetic compatibility.
For achieving the above object, the technical solution of the utility model is that a kind of circuit structure of car air-conditioner blower fan is characterized in that: the two ends that described circuit structure is air-conditioning draught fan are respectively by accessing splicing ear after inductance L 1, L2; The two ends of air-conditioning draught fan connect respectively ground connection after capacitor C 4, C5, ground connection after capacitor C 1, C2, C3 series connection.
Described ground wire connects the air-conditioning draught fan shell.
A kind of circuit structure of car air-conditioner blower fan, owing to adopting above-mentioned circuit structure, the utility model has the advantage of: the Electro Magnetic Compatibility that 1, can actv. promotes the blower fan that can't meet the demands without electromagnetic compatibility and electromagnetic compatibility; 2, simple to operate, technique realizes convenient.
The accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail;
The circuit diagram of the circuit structure that Fig. 1 is a kind of car air-conditioner blower fan of the utility model;
The specific embodiment
The utility model can effectively improve blower fan conduction interference performance and radiation disturbance performance, thereby improves the electromagnetic compatibility of blower fan, avoids other electrical component work is caused to interference.
The parts that the utility model relates to have comprised, capacitor C 1, capacitor C 2, capacitor C 3, capacitor C 4, capacitor C 5, inductance L 1, inductance L 2.By wire, the mode by Fig. 1 is connected described parts, the Electro Magnetic Compatibility in the time of can effectively improving blower fan work.
Specifically as shown in Figure 1, the two ends of air-conditioning draught fan are respectively by accessing splicing ear after inductance L 1, L2; The two ends of air-conditioning draught fan connect respectively ground connection after capacitor C 4, C5, ground connection after capacitor C 1, C2, C3 series connection.Ground wire connects the air-conditioning draught fan shell.
The superior part of this patent is, the first, can actv. promote the Electro Magnetic Compatibility of the blower fan that can't meet the demands without electromagnetic compatibility and electromagnetic compatibility; The second, simple to operate, technique realizes convenient.
The above is exemplarily described the utility model by reference to the accompanying drawings; obviously the utility model specific implementation is not subject to the restrictions described above; as long as the various improvement that adopted technical solutions of the utility model to carry out; or directly apply to other occasion without improvement, all within protection domain of the present utility model.
