Description
Technical Field
The utility model relates to a magnetic core technical field, more specifically say, it relates to a good heat dissipation's magnetic core.
Background
The magnetic core is a magnetic core sintered magnetic metal oxide with good heat dissipation property and composed of various iron oxide mixtures, manganese-zinc ferrite and nickel-zinc ferrite are typical magnetic core body materials, the manganese-zinc ferrite has the characteristics of high magnetic conductivity and high magnetic flux density and has the characteristic of low loss, the nickel-zinc ferrite has the characteristics of extremely high impedance rate, low magnetic conductivity of less than hundreds of percent and the like, and the ferrite core is used for coils and transformers of various electronic equipment.
When the electronic equipment works, the magnetic core can generate a large amount of heat, the heat dissipation effect of the existing special-shaped magnetic core is poor, and the situation that the electronic equipment cannot be normally and practically used due to overhigh temperature can occur. Therefore, a new technical solution is needed to solve the above problems.
SUMMERY OF THE UTILITY MODEL
Not enough to prior art exists, the utility model aims to provide a good heat dissipation's magnetic core.
In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides a good heat dissipation's magnetic core, includes the wrapping post, the bottom plate that two horizontal symmetries of bottom fixedly connected with of wrapping post circumference lateral wall set up, the vertical coreboard that sets up of the equal fixedly connected with of tip of two bottom plates, the coreboard orientation is circular-arcly around showing the surface of post, the wrapping post has seted up logical groove along its axle center direction, lead to the groove and run through in the top of wrapping post and the lower surface of bottom plate, a plurality of guiding gutters have been seted up along vertical direction on the circumference surface of wrapping post, the both ends of guiding gutter all run through in the both ends of wrapping post.
Through adopting above-mentioned technical scheme, wind the coil on the wrapping post, play the guard action to the magnetic core through the coreboard, and through circular-arc surface, increase its area of contact with the coil, promote to set up logical groove through the axle center department of rewinding post to the coil guard action, make the wrapping post can give off the interior logical inslot with the heat that absorbs from the coil, the heat gives off in the external environment through leading to the groove, in order further to promote its radiating effect, the partial heat of wrapping post surface gives off in the guiding gutter, and give off in the external environment through the air flow of guiding gutter, further promote its radiating effect.
The utility model discloses further set up to: the side walls of the two sides of the bottom plate incline towards the wrapping posts, and arc grooves attached to the surfaces of the circumferential side walls of the wrapping posts are formed in the side wall, facing the wrapping posts, of the bottom plate.
Through adopting above-mentioned technical scheme, reduced the area of contact between bottom plate upper surface and the coil for can have more area of contact with external environment on the coil, can directly give off more heats to external environment in, in order to promote the radiating effect, and reduce the material cost of bottom plate.
The utility model discloses further set up to: the core protection plate is provided with air guide grooves penetrating through the surfaces of two sides of the core protection plate.
By adopting the technical scheme, partial heat generated by the coil contacted with the inner wall of the core protection plate enters the external environment through the air guide groove, and the heat on the core protection plate is directly emitted into the air guide groove to be emitted into the external environment so as to further improve the heat radiation effect.
