[0037] Example 2:
[0038] See also Figures 1 to 7 Compared with the first embodiment, the present invention further includes a composite winding structure of a multi-layer stacked 5S inductor. The flow guide 16 includes a heat-insulating shell 161 fixedly mounted on the bottom of the insulating frame 11; a heat-collecting plate 162 is fixedly mounted on the left side of the heat-insulating shell, and a honeycomb-shaped flow-collecting hole is provided on the surface of the heat-collecting plate 162; a coil plate 163 is fixedly mounted on the right wall of the heat-insulating shell 161; a spring 164 is welded to the left end of the coil plate 163; a permanent magnet 165 is fixed to the left end of the spring 164. ; A heat insulation plate 166 is fixedly installed on the left end of the permanent magnet 165; a porous rubber body 167 is adhered to the left side of the inside of the heat-insulating shell 161; the coil plate 163 is fixedly connected to the energy supply 168 through a cable, and the energy supply 168 is fixedly installed on the inner wall of the heat-insulating shell 161; the vibration frequency of the permanent magnet 165 of the guide member 16 is synchronized with the frequency of the pulse current output by the energy supply 168, and the aperture of the honeycomb guide hole is gradually reduced along the airflow direction, forming a Venturi effect to enhance the airflow velocity of the heat dissipation duct.
[0039] The working principle of the composite winding structure of the multi-layer stacked 5S inductor is as follows:
[0040] First, when using the device, first place the device in the working area, and then connect the device to an external power source to provide the power required for the device to operate. By setting up a stacked structure of the first coil 121, the second coil 125, and the third coil 126, the component structure is relatively simple, and it can also form a hybrid winding 12 with alternating stacked spiral windings and planar windings, taking into account both low-frequency and high-frequency performance;
[0041] Second, heat is generated during the operation of the first coil 121, the second coil 125, and the third coil 126. The thermal conductivity of the aluminum nitride ceramic sheet 1241 transfers part of the heat to the piezoelectric ceramic 1242 and the memory alloy 1243. At the same time, the control element 1245 can also supply energy to the piezoelectric ceramic 1242 and the memory alloy 1243, causing the piezoelectric ceramic 1242 and the memory alloy 1243 to heat up rapidly and partially deform. This allows the magnetic absorbing material 123 to form a dynamically adjustable interlayer spacing to optimize inductance and heat dissipation. The insulating material characteristics of the insulating film 1244 are used to protect the piezoelectric ceramic 1242 and the memory alloy 1243.
[0042] Third, by supplying energy to the two sets of coils 156 inside the magnetic-isolating housing 155 respectively, the magnetic fields of the two sets of coils 156 are changed, pushing the sliding post 157 to slide inside the magnetic-isolating housing 155, thereby driving the elastic member 152 and the contact ball 153 through the insulating post 154 to contact the external connector 127 on the rear side of the hybrid winding 12, the high-frequency winding 13, and the low-frequency winding 14, thereby forming an electrical connection. With the help of the conductive properties of the elastic member 152 and the contact ball 153, the hybrid winding 12 and the power connection plate inside the inductor 1 are connected through the conductive plate 151. By adjusting the contact position of the hybrid winding 12, the number of turns of the current flowing through the hybrid winding 12 is changed, thereby changing the effective number of turns of the hybrid winding 12, the high-frequency winding 13, and the low-frequency winding 14.
[0043] Fourth, a large amount of heat is generated during the operation of the inductor 1. Here, the energy supply 168 is used to provide intermittent energy to the coil plate 163. After being energized, the coil plate 163 intermittently pushes the permanent magnet 165. The magnetic field effect between the permanent magnet 165 and the coil plate 163 causes the spring 164 to push the permanent magnet 165 to slide inside the thermal insulation shell 161 and squeeze the porous rubber body 167. Here, the airflow inside the porous rubber body 167 is squeezed out, driving the airflow inside the inductor 1 to accelerate the flow, helping the inductor 1 to dissipate heat. When the airflow inside the porous rubber body 167 flows out, it also carries away the heat from the heat collecting plate 162. The intermittent movement of the permanent magnet 165 also temporarily stops squeezing the porous rubber body 167. The porous rubber body 167 uses air pressure to re-absorb the external airflow into it. The compression between the permanent magnet 165 and the porous rubber body 167 causes deformation, which drives the airflow inside the inductor 1.
[0044] The present invention provides an improved composite winding structure of a multi-layer stacked 5S inductor. By integrating the composite windings of a hybrid winding 12, a high-frequency winding 13, and a low-frequency winding 14, the complexity of the components is simplified while being compatible with both low-frequency and high-frequency electromagnetic characteristics. The thermal conductivity of the aluminum nitride ceramic sheet 1241 and the deformation response of the piezoelectric ceramic 1242 and the memory alloy 1243 are utilized to construct a thermal-mechanical coupling intelligent control system, dynamically adjust the interlayer spacing of the magnetic absorbing material 123 to optimize the inductance and accelerate heat dissipation, and achieve insulation protection of key components through the insulating material film 1244. Based on the contact switching mechanism of the sliding column 157 driven by the magnetic field, the effective number of turns of the hybrid winding is adjusted in real time, giving the inductance parameters dynamic adjustability. The magnetic-elastic interaction between the permanent magnet 165 and the porous rubber body 167 is further combined to generate airflow through intermittent extrusion, and cooperate with the heat collecting plate to achieve cyclic forced air cooling and heat dissipation.
