[0019] like Figure 1 and Figure 2 As shown, a novel SQ-shaped power inductor of this embodiment includes an integral die-cast magnetic core 2, two coils 1 connected in series, a partition 3 and a bottom plate 4;

[0020] The magnetic core 2 includes two integrally connected columns 21 and two fixed blocks 22. The two columns 21 are located between the two oppositely arranged fixed blocks 22. The two coils 1 are respectively wound on the outer walls of the two columns 21. The partition 3 is arranged between the two coils 1. The bottom of the partition 3 is fixedly connected to the bottom plate 4. Support members are fixedly provided on both sides of the coil 1. The support members are fixedly sleeved on the columns 21. The bottom of the support members is fixedly connected to the bottom plate 4.

[0021] Specifically, in this embodiment, the two coils 1 are connected in series with each other, which is essentially equivalent to one coil 1. The partition 3 is made of insulating material and is arranged between the two coils 1, mainly for isolating the two coils 1. Secondly, the partition 3 is also fixedly connected to the bottom plate 4 and is arranged at the center of the magnetic core 2. It can fix the magnetic core 2 when the magnetic core 2 shakes, thereby improving the structural stability of the magnetic core 2.

[0022] Preferably, Figure 3 As shown, a protective shell 5 made of heat-conducting material is fixedly provided on the upper end of the bottom plate 4 , and the magnetic core 2 , the two coils 1 and the partition 3 are all arranged in the protective shell 5 .

[0023] Specifically, in this embodiment, by providing the protective housing 5 , the power inductor can be prevented from being directly corroded by the external environment, thereby increasing the service life of the internal components of the power inductor.

[0024] Preferably, a plurality of air inlet holes 6 are provided on the top of the protective shell 5 , and a plurality of air outlet holes 7 are provided on two opposite sides of the protective shell 5 .

[0025] Specifically, in this embodiment, by providing a plurality of air inlet holes 6 and a plurality of air outlet holes 7 on the protective shell 5, the heat generated by the inductor and the magnetic core 2 inside the protective shell 5 can be circulated with the external air, thereby achieving heat dissipation.

[0026] Preferably, a heat dissipation assembly is detachably mounted on the top of the protective shell 5 , and the heat dissipation assembly includes a heat dissipation bracket 8 and a heat dissipation fan 9 , the air inlet end of the heat dissipation fan 9 faces upward, and the air outlet end of the heat dissipation fan 9 faces each air inlet hole 6 .

[0027] Specifically, in this embodiment, the cooling fan 9 blows external cold air into the air inlet holes 6, takes away the heat generated by the magnetic core 2 and the inductor surface, and finally flows out from the air outlet holes 7. The cooling fan 9 accelerates the air flow inside and outside the protective shell 5, improves the heat dissipation effect of the magnetic core 2 and the two inductors inside the protective shell 5, and extends the service life of the power inductor.

[0028] Preferably, a plurality of clips 10 are provided at the bottom of the heat dissipation bracket 8, and a plurality of slots 11 are also provided at the top of the protective shell 5. The shape and position of each slot 11 are adapted to the corresponding clip 10, and each clip 10 is buckled into the corresponding slot 11.

[0030] Preferably, a dustproof net is provided on the inner side of each air inlet hole 6 and each air outlet hole 7.

[0031] Specifically, in this embodiment, a dustproof net is provided to prevent external dust from entering the interior of the protective shell 5 during the air circulation inside and outside the protective shell 5, thereby preventing the normal use of the internal magnetic core 2 and coil 1. Therefore, the provision of a dustproof net improves the stability of the use of the power inductor.

[0032] Preferably, fixing grooves are provided on two opposite inner side walls of the protective shell 5 , and the fixing blocks 22 are embedded in the fixing grooves.

[0033] Specifically, in this embodiment, by providing a fixing groove and embedding the fixing block 22 in the fixing groove, a fixed connection between the protective shell 5 and the magnetic core 2 is achieved, thereby improving the installation structure stability of the magnetic core 2.

[0034] Working principle:

[0035] This technical solution directly uses a one-piece die-cast magnetic core 2, eliminating the need to assemble two magnetic cores 2 during the power inductor installation process, simplifying the power inductor installation process and improving the installation efficiency of the power inductor. The tolerance of the original two magnetic cores 2 spliced ​​together to form the entire magnetic core 2 was ±12%, while the tolerance of the one-piece die-cast magnetic core 2 selected in this technical solution is ±8%. Therefore, compared with the spliced ​​magnetic core 2, the use of the one-piece die-cast magnetic core 2 significantly reduces the installation tolerance of the power inductor and improves the installation accuracy.
