Embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, clear and definite, referring to the accompanying drawing embodiment that develops simultaneously, the utility model is further described.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 3, Fig. 3 is the structural representation of the preferred embodiment of the flat described output filtering heavy-current inductor of the utility model, and described output filtering heavy-current inductor, comprising:
By the bonding rectangular-shaped iron core 100 being formed by stacking of magnetic core 101 of multiple bulks, and being arranged on the Copper Foil winding (not marking in figure) in the passage of described iron core, a Copper Foil pin 200 for connecting circuit board is respectively drawn at the passage two ends of described rectangular-shaped iron core 100 from Copper Foil winding.
In the utility model preferred embodiment, rectangular-shaped iron core 100 is by bonding being formed by stacking of multiple magnetic cores 101, therefore it is simple to produce the technique of described iron core 100, improved greatly the production efficiency of iron core.In the described iron core 100 of bonding stack, the passage of one shape and Copper Foil winding adaptation is set on described iron core 100, and described Copper Foil winding is arranged in described iron core 100, finally respectively draw a Copper Foil pin 200 for connecting circuit board from the relative two sides of iron core 100.
Preferably, described magnetic core 101 is rectangular-shaped.For more convenient in bonding multiple magnetic cores 101, therefore magnetic core 101 is set to rectangular-shaped, the bonding stack of multiple little rectangular-shaped magnetic core can be obtained to a large rectangular-shaped iron core 100.Adopt rectangular structure simultaneously, increased the contact area of iron core and air, therefore block inductance has splendid thermal diffusivity.Concrete, as shown in Figure 3 and Figure 4, described iron core 100 is formed by stacking by 8 sizes, magnetic core that shape is identical.
Preferably, described magnetic core 101 forms described rectangular-shaped iron core by the bonding stack of heat-conducting glue.Heat-conducting glue is to replace heat-conducting silicone grease (cream), bonding as the filling between CPU and radiator, intelligent control module with thyristor and radiator, high-power electric appliance module and radiator.With removing traditional connected mode with card and screw after heat conduction, bring and fill more reliably heat radiation, simpler technique, more economical cost.
Preferably, the material of described magnetic core 101 is iron sial.Iron sial is a kind of high performance-price ratio core material, is the substitute of ferrocart core.The magnetic property of Fe-Si-Al magnetic core is close with high flux powder core, and loss ratio high flux powder core is low, but its price is cheaply many.Therefore, use is also more and more extensive in recent years.Every place that can replace MPP, high flux powder core all can adopt Fe-Si-Al magnetic core as far as possible.The standard analysis of sendust is: AL5.4%; Si9.6%; All the other are iron.
