Description
Technical field
The present invention relates to circuit element field of radiating, specifically a kind of high-power inductance radiator.
Background technology
Inductance is one of component indispensable in electronic circuit, and inductance converts electrical energy into magnetic energy, leads in circuit
The effects that playing filtering, oscillation, delay, trap also screens signal, crosses noise filtering, stabling current and inhibit electromagnetic wave dry
The effects that disturbing, in Switching Power Supply, generally there are multiple high-power inductance, inductance can be on coil and iron core when passing through high current
Assemble heat, overheat can reduce the performance of inductance for a long time, reduce the service life of inductor, common cooling fin is difficult to secohmmeter
Face and internal uniform radiating, radiating efficiency be not high.
Invention content
Technical problem to be solved by the present invention lies in a kind of high-power inductance radiator is proposed, inductance heat dissipation effect is improved
Rate.
The technical problems to be solved by the invention are realized using following technical scheme：
A kind of high-power inductance radiator, includes the shell and side cover plate of arc-shaped, and the bottom margin of the shell is affixed
It is useful for being welded to the fixation stitch on circuit board, there are the heat emission hole for stretching into the enclosure, institute in the centre of the side cover plate
Stating side cover plate surface has the first radiating fin of radial arrangement, the annulus edge of the shell to be connected with the second radiating fin.
The inner peripheral surface of the shell has outer teeth groove, the outer surface of the heat emission hole to have internal spline.
The outer teeth groove is with internal spline for coating heat dissipating silicone grease.
The heat emission hole is manufactured using copper material, and the shell is manufactured using aluminium material.
The beneficial effects of the invention are as follows the heat dissipation area to high-power inductance is big, inductance coil inside can be dissipated
Heat further increases radiating efficiency using silicone grease, easy for installation.
Description of the drawings
Present invention will be further explained below with reference to the attached drawings and examples.
Fig. 1 is the dimensional structure diagram one of the present invention；
Fig. 2 is the dimensional structure diagram two of the present invention.
Specific implementation mode
In order to make the technical means, the creative features, the aims and the efficiencies achieved by the present invention be easy to understand, below it is right
The present invention is expanded on further.
As shown in Figure 1：
A kind of high-power inductance radiator, includes the shell 1 and side cover plate 3 of arc-shaped, and the bottom margin of the shell 1 is solid
It is connected to the fixation stitch 2 for being welded on circuit board, the arc-shaped structure of the shell 1 can wrap the outer of inductance coil
End；
The centre of the side cover plate 3 has the heat emission hole 4 stretched into inside the shell 1, the heat emission hole 4 to can extend into inductance
In the annulus of iron core, the position that accumulated heat is easy to inductance inside carries out heat conduction and heat radiation；
3 surface of the side cover plate has the first radiating fin 5 of radial arrangement, the side cover plate 3 to be with the heat emission hole 4
It is connected directly, the heat emission hole 4 is passed to from the heat of inductance absorbed inside on the side cover plate 3, passes through the side cover
First radiating fin 5 on 3 surface of plate increases the contact area with air, and inductance internal heat is distributed；
The annulus edge of the shell 1 is connected with the second radiating fin 6, and inductance surrounded surface heat is distributed.
As shown in Figure 2：
The inner peripheral surface of the shell 1 has outer teeth groove 7, the outer surface of the heat emission hole 4 to have internal spline 8；
For the outer teeth groove 7 with internal spline 8 for coating heat dissipating silicone grease, tooth socket can singly not increase certain heat dissipation area,
Silicone grease can be tangled simultaneously, so that silicone grease is unlikely to because Gravitational sliding is accumulated, but is uniformly filled between inductance and radiator
Gap in；
The heat emission hole 4 is manufactured using copper material, and the shell 1 is manufactured using aluminium material, and copper material has higher heat conduction
Coefficient, the heat derives that will quickly can assemble inside inductor, and aluminium material then has more preferable plasticity and economy, is convenient for
Manufacture and control cost.
The basic principles, main features and advantages of the present invention have been shown and described above.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and what is described in the above embodiment and the description is only the present invention
Principle, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these variation and
Improvement all fall within the protetion scope of the claimed invention.The claimed scope of the invention is by appended claims and its equivalent
Object defines.
