Specific embodiment
The utility model is further described with reference to the accompanying drawing.
Embodiment one
Heat radiating type FERRITE CORE as shown in Fig. 1, includes core body 10, and core body includes bottom plate 11, bottom plate
11 center is provided with magnetic pole 12；There are two symmetrically arranged V-arrangement slot 13 and two are symmetrical for tool on the bottom plate 11
The straight rib 14 being arranged constitutes the coil accommodation groove for accommodating coil between each straight rib 14 and the magnetic pole 12；
On the length direction of the straight rib 14, the length of the straight rib 14 in this direction is longer than the magnetic pole 12 in the direction
On length.The bottom plate 11, magnetic pole 12 and straight 14 three of rib are integrally formed, and generally, three is by Ferrite Material
Once sintered molding.
Above-mentioned magnetic core by the bottom plate be arranged V-arrangement slot 13 so that the side for the coil being mounted in magnetic core with
And bottom can be carried out preferable heat dissipation, the setting of V-arrangement slot can also facilitate the lead-out wire of coil to lead to outside magnetic core, while straight
The design long compared with magnetic pole 12 of rib 14 can guarantee that magnetic core leakage field is less, guarantee the basic nature of magnetic core while guaranteeing heat dissipation performance
Energy.
The shape of the magnetic pole 12 is strip, and length direction is consistent with the length direction of straight rib 14, and its both ends
It is semicircle, the coil accommodation groove constituted between rib 14 straight in this way and the magnetic pole 12 is longer, and the magnetic core conjugate profile is same
Sample is that the coil of long waist shaped uses, and may make the major part for the coil being mounted in magnetic core to be placed in coil accommodation groove, is guaranteeing
The performance of magnetic-leakage preventing is further promoted while thermal diffusivity.
Optionally, the slot bottom of the V-arrangement slot 13 is arc-shaped, and the shape of the circular arc of its slot bottom and 12 end of magnetic pole
Shape agrees with, and in this way in perception, the sub-fraction of the end of magnetic pole 12 extends to the bottom of bottom plate 11, this design so that
Core structure is relatively simple, carries out whole stripping forming to magnetic core when being conducive to production and is sintered operation again, on the other hand,
In overlook direction, V-arrangement slot 13 extends to the edge of the circumference line of magnetic pole 12, but also the lead-out wire of coil is drawn more
It is convenient.
