The magnetic core body comprises a left support leg, a base and a right support leg. A semi-opening structure is formed by the left support leg, the base and the right support leg. The middle column, disposed at the middle position of the base, is symmetrically provided with the left support leg and the right support leg. The middle column, kidney-shaped column, is provided with a first through hole in a vertical direction. A second through hole and a third through hole, vertically arranged, are respectively formed in the left support leg and the right support leg. The first through hole, the second through hole and the third through hole are internally adhered to radiating fins provided with radiating teeth by extending outwardly towards through holes. The heat-radiating magnetic core has following beneficial effects: due to the fact that the column, the left support leg and the right support leg are internally provided with the through holes and the through holes are internally provided with the radiating fins with the radiating teeth by extending outwardly towards the through holes, heat conducted by the magnetic core body and the middle column is dispersed to the air; and the heat-radiating magnetic core is fine in radiating effect and low in cost and is also capable of rapidly reducing heat produced by an operating process of the magnetic core.
Description
Technical field
The utility model relates to a kind of magnetic core, is specifically related to a kind of heat radiation magnetic core with wider temperature applicable range.
Background technology
Along with the development of technology, electronic product is gradually to microminiaturized, powerful future development, and magnetic core can distribute amount of heat in the course of the work, must cause electromagnetic device to heat up very fast, if heat radiation not in time, electromagnetic device just likely damages.Therefore; the heat sinking function of magnetic core is focus and the emphasis of paying close attention in the industry, and more in the industry is at present to adopt the mode of casing+heat conductive pad to dispel the heat, but which heat radiation is unstable; usually can be because the distortion of heat conductive pad causes heat radiation unreliable, and cost is higher.
Utility model content
For solving the deficiencies in the prior art, the purpose of this utility model is to provide the one magnetic core that dispels the heat cheaply.
In order to realize above-mentioned target, the utility model adopts following technical scheme:
A kind of heat radiation magnetic core, comprise magnetic core body and with the integrated center pillar of magnetic core body, described magnetic core body comprises the left branch leg that forms semi-open structure, base and right supporting leg, described center pillar is positioned at the centre position of base and left branch leg and right supporting leg about center pillar symmetry, described center pillar is kidney-shaped post, in described center pillar, be formed with the first through hole that vertical direction arranges, in described left branch leg and right supporting leg, be formed with respectively the second through hole and the 3rd through hole of longitudinal setting, described the first through hole, in the second through hole and the 3rd through hole, be all fitted with fin, described fin has radiation tooth to through hole extension.
Aforementioned fin and radiation tooth are made up of metal material, and described metal material is iron or copper.
Aforementioned fin is pasted in the first through hole, the second through hole and the 3rd through hole by heat-conducting glue.
Aforementioned left branch leg and right supporting leg are bent to form arcwall face near the medial surface of center pillar to the direction away from center pillar.
The horizontal end face of aforementioned base is bent to form arcwall face to the direction near center pillar.
Further, the fin in aforementioned the first through hole stretches out from the top of the first through hole, forms laterally and the radiation tooth of vertical direction.
Closer, the fin in aforementioned the second through hole and the 3rd through hole stretches out from the two ends of through hole, forms laterally and the radiation tooth of vertical direction.
Usefulness of the present utility model is: magnetic core of the present utility model, its center pillar, left branch leg, right supporting leg inside are all formed with through hole, in through hole, be fitted with fin and fin and have radiation tooth to through hole extension, the dissipation of heat that magnetic core body and center pillar are conducted is out to air, good heat dissipation effect, cost are low, and the heat that magnetic core can be produced in the course of the work reduces rapidly.
Brief description of the drawings
Fig. 1 is the structural representation of the specific embodiment of a kind of magnetic core that dispels the heat of the present utility model.
The implication of Reference numeral in figure: 1, magnetic core body, 101, left branch leg, 102, base, 103, right supporting leg, 2, center pillar, 3, fin, 4, radiation tooth.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is done to concrete introduction.
Referring to Fig. 1, a kind of heat radiation magnetic core of the present utility model comprise magnetic core body 1 and with the integrated center pillar 2 of magnetic core body 1.Wherein, magnetic core body 1 comprises the left branch leg 101, base 102 and the right supporting leg 103 that form semi-open structure, and center pillar 2 is positioned at the centre position of base 102 and left branch leg 101 and right supporting leg 103 about center pillar 2 symmetries, and particularly, center pillar 2 is kidney-shaped post.As shown in Figure 1, in center pillar 2, be formed with the first through hole that vertical direction (i.e. Z-direction shown in figure) arranges, interior the second through hole and the 3rd through hole that is formed with respectively longitudinally (i.e. Y direction shown in figure) setting of left branch leg 101 and right supporting leg 103, in the first through hole, the second through hole and the 3rd through hole, be all fitted with fin 3, and fin 3 there is radiation tooth 4 to through hole extension.So, magnetic core body 1 and center pillar 2 just can be distributed to heat out of conduction in air in time, and good heat dissipation effect, cost are low.
Preferably, fin 3 and radiation tooth 4 are made up of metal material, and metal material is iron or copper.
As a kind of embodiment, fin 3 is pasted in the first through hole, the second through hole and the 3rd through hole by heat-conducting glue, and heat-conducting glue can further be optimized radiating effect.
Further, left branch leg 101 and right supporting leg 103, have formed intermediate thin, the thick structure in two ends, and then have ensured that in use magnetic core temperature is everywhere basically identical to being bent to form arcwall face away from the direction of center pillar 2 near the medial surface of center pillar 2.More preferably, the horizontal end face of base 102 is bent to form arcwall face to the direction near center pillar 2, and this structure contributes to the heat radiation of magnetic core body 1 more.
As shown in Figure 1, the fin 3 in the first through hole stretches out from the top of the first through hole, forms the radiation tooth 4 of horizontal (i.e. X-direction shown in figure) and vertical direction (i.e. Z-direction shown in figure).Further, the fin 3 in the second through hole and the 3rd through hole stretches out from the two ends of through hole, forms laterally and the radiation tooth 4 of vertical direction.
More than show and described general principle of the present utility model, principal character and advantage.The technical staff of the industry should understand, and above-described embodiment does not limit the utility model in any form, and all employings are equal to replaces or technical scheme that the mode of equivalent transformation obtains, all drops in protection range of the present utility model.
