For achieving the above object, the utility model provides a kind of inductance ventilation radiator structure, be arranged at the middle part of inductance, this inductance is provided with a magnetic body in the outside of its helical conductor coil, through hole in conductor coils inside is provided with a magnetic core body, and two opposite end portions of conductor coils are exposed to magnetic body; Wherein: this inductance is provided with a vent cap that axially runs through the outside opposite side of magnetic core body and magnetic body, to constitute the access lane of outside air.

In preferred embodiment, this inductance is laterally or up and down directly to being provided with conductor coils and through hole thereof, makes vent cap laterally or up and down directly to connecting the outside two opposite sides of magnetic body.

In preferred embodiment, this magnetic body and magnetic core body can be made as disjunctor press type body or formed body separately.

In preferred embodiment, each laterally is provided with a relative through hole the outside two opposite sides of this magnetic body, and this magnetic core body inside is provided with axial vent cap, runs through the two relative through holes of magnetic body and the through hole of conductor coils inside with plant.

Owing to take above technical scheme, the utlity model has following beneficial effect: the magnetic body of inductance of the present utility model own is provided with the vent cap that axially runs through conductor coils, therefore heat dissipation path and area thereof have been increased, radiating efficiency and radiating rate have been improved, guarantee inductance usefulness and stability, and meet the environmental protection and energy saving requirement, be fit to automatic mass.

Embodiment

Relevant the utility model is for reaching above-mentioned purpose, and technological means that is adopted and effect thereof enumerate possible embodiments now, and conjunction with figs. are described as follows:

At first, see also Fig. 1, Fig. 2 and Fig. 3, the utility model inductance ventilation radiator structure mainly is applicable on the compacting pattern power inductance, with the one-body molded radiator structure that goes out to ventilate in the middle part of inductance.As shown in FIG., inductance is combined with magnetic body 1 in its helical conductor coil 2 outside pressing and wrapping, and two

opposite end portions

22,23 of conductor coils 2 and spiral coil portion thereof are exposed to magnetic body 1 bottom, uses pin to constitute to electrically connect.

In preferred embodiment, the magnetic body 1 and the magnetic core body 3 of inductance can be made as disjunctor press type body, and adopt iron, manganese, nickel, magnesium and other magnetic oxide powder stocks, to meet inductance desirable characteristics value, mix cement and plastics again.In addition, more can add the heat conduction raw material, for example silicon, aluminium and other metals or nonmetal heat conduction raw material, and can add general oxidation-resistant material.
