An inductance assembly 100 of an air conditioner according to an embodiment of the present invention is described below with reference to fig. 1.
As shown in fig. 1, an inductance assembly 100 of an air conditioner according to an embodiment of the present invention, the inductance assembly 100 includes: a base 10 and a PFC inductor 20. Specifically, the base 10 is an insulating member, and the PFC inductor 20 is connected to the base 10. Thus, the PFC inductor 20 may be fixed to other parts of the air conditioner through the base 10, facilitating the fixed assembly of the PFC inductor 20. Moreover, by providing the base 10 as an insulating member, when the PFC inductor 20 is fixed to other components of the air conditioner through the base 10, the insulating base 10 can insulate and connect the PFC inductor 20 and the other components of the air conditioner, thereby blocking electromagnetic interference (EMI) between the PFC inductor 20 and the other components, further preventing electromagnetic interference signals from forming a resonant circuit and avoiding electromagnetic interference (EMI) noise signals, and solving the problem of electromagnetic interference (EMI) of the PFC inductor 20 in the air conditioner at a lower cost.
In the related art, the PFC inductor core of the air conditioner is made of silicon steel sheet, the PFC inductor is fixed on the middle partition board of the outer machine of the air conditioner, and the metal base for fixing the PFC inductor is directly welded on the silicon steel sheet core. Thus, the extremely high dV/dt noise on the PFC inductance coil is transmitted to the partition board in the case through the distributed capacitance between the PFC inductance coil and the silicon steel sheet iron core.
The electromagnetic interference (EMI) noise signal conduction paths are: interference noise of an EMI interference source of the PFC circuit is firstly transmitted to the PFC inductor, is coupled to the iron core and the base through a distributed capacitor between the PFC inductor and the silicon steel sheet iron core, is transmitted to the middle baffle through a conductive path of a fixing structure of the base and the middle baffle metal plate, is transmitted to a 50 ohm sampling resistor through a power ground wire (PE), is transmitted to an LISN (electromagnetic interference voltage testing device) through a 50 ohm sampling resistor of the LISN, and is returned to the electromagnetic interference (EMI) source of the PFC circuit through a live wire and a zero wire (L/N) of the air conditioner, so that the electromagnetic interference (EMI) noise signal is detected by the 50 ohm sampling resistor of the LISN. At the same time, at some higher frequency points, electromagnetic interference (EMI) noise signals also resonate on the loop described above, amplifying the electromagnetic interference (EMI) noise signals.
In the inductor assembly 100 of the air conditioner according to the embodiment of the present invention, the base 10 is provided as an insulating member, and the PFC inductor 20 may be fixed in the air conditioner through the insulating base 10, so as to facilitate the fixed assembly of the PFC inductor 20. Moreover, because the base 10 is an insulating part, the PFC inductor 20 can be connected with other parts in the air conditioner in an insulating way, and the PFC inductor 20 is effectively prevented from transmitting electromagnetic interference signals to the other parts, so that electromagnetic interference amplification caused by the formation of a resonant loop by electromagnetic interference noise is prevented, and the electromagnetic interference noise signal of the PFC inductor 20 in the air conditioner is reduced with lower cost.
According to some embodiments of the present invention, PFC inductor 20 is snapped into base 10. Thereby, the fixed assembly between the PFC inductor 20 and the base 10 is facilitated, so that the assembly efficiency of the PFC inductor 20 can be improved. Moreover, the PFC inductor 20 and the base 10 are connected in a clamping manner, so that the PFC inductor 20 is convenient to disassemble, and maintenance and replacement of the PFC inductor 20 are facilitated.
Further, the base 10 has a clamping groove, and a part of the PFC inductor 20 is located in the clamping groove. Therefore, the PFC inductor 20 can be assembled with the base 10 in a clamping way through the clamping groove, and is convenient to operate and high in assembly efficiency. In addition, the clamping groove structure is easy to process and manufacture, and the processing technology of the base 10 can be simplified, so that the production cost can be reduced. It is understood that the clamping groove may be configured as a groove structure adapted to the outer contour of the fitting portion of the PFC inductor 20, and the PFC inductor 20 and the clamping groove may be assembled by interference fit, so as to enhance the firmness of the assembly between the PFC inductor 20 and the clamping groove.
In some embodiments of the invention, PFC inductor 20 may be bonded to base 10. For example, glue may be applied to the connection location between the PFC inductor 20 and the base 10 to firmly fix the PFC inductor 20 to the base 10. Thus, the assembling efficiency of the PFC inductor 20 can be improved, and the assembling between the PFC inductor 20 and the base 10 can be made firm and reliable. It is understood that the connection between the PFC inductor 20 and the base 10 is not limited to clamping and bonding, but may be a binding connection or other connection methods.
Alternatively, the base 10 may be a plastic piece. It can be understood that the base 10 is made of plastic, the plastic material is low in price, and the base 10 is convenient to process and manufacture, so that the production cost can be reduced; in addition, the plastic part has good insulating property, and can effectively block the electric connection between the PFC inductor 20 and other parts in the air conditioner, so that the transmission of electromagnetic interference signals of the PFC inductor 20 is prevented. Moreover, the plastic base 10 has a low density, and the overall weight of the inductance assembly 100 can be reduced.
According to some embodiments of the present invention, as shown in fig. 1, the base 10 may have a heat dissipation hole 110. It can be appreciated that the PFC inductor 20 generates heat during operation, and by providing the heat dissipation holes 110 in the base 10, the heat of the PFC inductor 20 can be timely dissipated, so as to prevent the PFC inductor 20 from being damaged due to too high temperature, or the base 10 is melted due to too high temperature of the PFC inductor 20, thereby improving the operation safety and stability of the inductor assembly 100.
Further, the heat dissipation holes 110 may be a plurality of spaced apart. Thus, by providing a plurality of heat dissipation holes 110 at intervals, the heat dissipation effect of the base 10 can be further improved, thereby improving the stability and reliability of the operation of the PFC inductor 20.
In some embodiments of the present invention, the plurality of heat dissipation holes 110 are uniformly distributed along the circumferential direction of the PFC inductor 20. It will be appreciated that the base 10 on the one hand has the function of fixing the PFC inductor 20; on the other hand, the function of isolating the PFC inductor 20 from electrical connection with other components in the air conditioner is achieved. Therefore, by arranging the heat dissipation holes 110 along the circumferential direction of the PFC inductor 20, the portion of the base 10 between the PFC inductor 20 and the middle partition 510 is sealed, so that the base 10 has a good heat dissipation effect, and the PFC inductor 20 is prevented from transmitting electromagnetic interference noise signals through the electrical connection between the heat dissipation holes 110 and the middle partition 510. In addition, the plurality of heat dissipation holes 110 are uniformly distributed along the circumferential direction of the PFC inductor 20, so that the uniformity of heat dissipation of the base 10 can be improved, and further, the heat dissipation effect of the base 10 is further improved.
