Embodiment approach 1
[0037]
[0038] refer to Figure 1 to Figure 3 , the reactor 1 according to Embodiment 1 will be described. figure 1 is a perspective view of the reactor 1 . exist figure 1 , let the horizontal direction be the x-axis, the vertical direction be the y-axis, and the depth direction be the z-axis. figure 2 is a cross-sectional view of the reactor 1 in the xz plane, image 3 It is a cross-sectional view of the reactor 1 in the yz plane passing through the center of the rings of the ring-shaped heat dissipation cases 30 and 31 .
[0039] The reactor 1 includes a magnetic member 100 and a coil 90 wound around the magnetic member 100 . The magnetic component 100 includes a plurality of split cores 10 , a core gap member 20 made of a non-magnetic material, heat dissipation cases 30 , 31 , and fixing members 60 , 61 .
[0040] The divided core 10 is a shape obtained by dividing a general annular core in the circumferential direction. That is, an annular core is configured by c...
Embodiment approach 2
[0067]
[0068] The configuration of the reactor 2 according to Embodiment 2 will be described below. The perspective view of reactor 2 is as follows figure 1 As shown, it is the same as the reactor 1 of the first embodiment. Figure 5 It is a cross-sectional view of the reactor 2 in the yz plane passing through the center of the ring of the heat dissipation cases 30 and 31 .
[0069] Reactor 2 includes first heat dissipation member 80 between the upper surface of split core 10 and heat dissipation case 30 and between the lower surface of split core 10 and heat dissipation case 31 . The configuration of the reactor 2 other than the first heat dissipation member 80 is the same as that of the reactor 1 in the first embodiment. In this way, by disposing the first heat dissipation member 80 between the split core 10 and the heat dissipation casings 30, 31, the contact between the split core 10 and the heat dissipation casings 30, 31 is less severe than when the split core 10 a...
Embodiment approach 3
[0080]
[0081] refer to Figure 8 to Figure 10 , the reactor 3 according to Embodiment 3 will be described. Figure 8 is a perspective view of the reactor 3 . exist Figure 8 , let the horizontal direction be the x-axis, the vertical direction be the y-axis, and the depth direction be the z-axis. Figure 9 is a sectional view of the reactor 3 in the xz plane, Figure 10 It is a cross-sectional view of the reactor 3 in the yz plane passing through the center of the ring of the annular heat dissipation case 33 .
[0082] The reactor 3 includes a heat dissipation case 33 instead of the heat dissipation cases 30 and 31 of the reactor 1 , and has a third heat dissipation member 83 on the upper surface of the split core 10 . The configuration of the reactor 3 other than the heat dissipation case 33 and the third heat dissipation member 83 is the same as that of the reactor 1 of the first embodiment.
[0083] The heat dissipation case 33 has an annular shape with one end surf...
