The metal winding penetrates through the shell and is connected with a terminal block, and a plurality of heat dissipating holes are formed in the iron core. A cavity is formed in the shell in the circumference direction, one end of the cavity is connected with a water inlet pipe, and the other end of the cavity is connected with a water outlet pipe. The iron core is made of ferrite materials, and the metal winding is made of a copper foil coil in a winding mode. The inductor is simple in structure and reasonable in design, water is injected into the cavity, heat dissipated out from the inductor is brought away through the water, circulating water is led into the cavity continuously and repeatedly used, and construction cost is low. The heat dissipating holes are formed in the iron core, and the heat dissipating effect can be further improved.
Description
Technical field
The utility model relates to electronic component technology field, relates in particular to a kind of inductor.
Background technology
Inductor, as a kind of main electronic component, is widely used in the design of various electronic circuits, is to realize the indispensable element of majority circuit function.The structure of inductor is similar to transformer, but only has a winding.Inductor has certain inductance, and it only stops the variation of electric current.If inductor is under the state that does not have electric current to pass through, when circuit is connected, it will attempt to stop electric current to flow through it; If inductor under the state that has electric current to pass through, when circuit disconnects it will to attempt to maintain electric current constant.So inductor can produce a large amount of heats in work, and inductor is all generally to be made by wire coil, the heat producing easily changes the temperature of wire coil, thereby changed the coefficient of performance of wire coil, the effect playing of inductor is weakened, and reduced the useful life of inductor.
It according to Chinese Patent Application No., is a kind of inductor of 201320596574.0 announcements, it comprises base and is fixed on the housing on base, on described base, center is fixed with iron core, on described base, be also fixed with wire coil, described iron core is positioned at wire coil center, described iron core and wire coil form magnetic core combination, described iron core and wire coil are all positioned at enclosure interior, described wire coil is connected with terminals through housing, described housing both sides are equipped with installing hole, described left side installing hole is provided with air intake fan, described right side installing hole is provided with out fan.The inductor of this structure is taken away by the heat that fan is set inductor winding is come out, and played good radiating effect, but external fan can cause the complex structure of inductor, and cost improves, and fan easily damages simultaneously, is unfavorable for maintenance.
Utility model content
The purpose of this utility model is in order to overcome the deficiencies in the prior art, and a kind of inductor is provided, and in order to improve its radiating effect, increases the service life.
The utility model is to be achieved through the following technical solutions:
An inductor, comprises metal shell, is provided with iron core and is wrapped in the metal winding on iron core in metal shell, and described metal winding is connected with binding post through housing, offers a plurality of louvres on described iron core; At housing, along the circumferential direction offer cavity, in one end of cavity, be connected with water inlet pipe, the other end is connected with outlet pipe.
As optimal technical scheme of the present utility model, described iron core adopts Ferrite Material to make, and described metal winding adopts Copper Foil coil winding to become, and the width of Copper Foil is 44mm, and thickness is 0.3mm.
As optimal technical scheme of the present utility model, described louvre is circular hole, is evenly arranged on iron core.
Compared with prior art, the beneficial effects of the utility model are:
1, simple in structure, reasonable in design, by injected water in cavity, the heat that inductor is come out is taken away by water, more constantly passes into recirculated water, reuses, and cost is low;
2, by offer louvre on iron core, improve further its radiating effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is A-A cutaway view in Fig. 1.
In figure: 1-metal shell; 2-iron core; 3-metal winding; 4-binding post; 5-louvre; 6-cavity 7-water inlet pipe; 8-outlet pipe; 9-back-up block.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.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. 1 and Fig. 2, Fig. 1 is structural representation of the present utility model, and Fig. 2 is A-A cutaway view in Fig. 1.
Described a kind of inductor, it is under the state that does not have electric current to pass through, when circuit is connected, it will attempt to stop electric current to flow through it, if it under the state that has electric current to pass through, during circuit disconnection it will to attempt to maintain electric current constant.This inductor comprises metal shell 1, is provided with iron core 2 and is wrapped in the metal winding 3 on iron core 2 in metal shell 1, and described iron core 2 and metal winding 3 form magnetic core combination.Described iron core 2 is fixedly mounted in housing 1 by the back-up block 9 at two ends.Described metal winding 3 is connected with binding post 4 through housing 1.
On described iron core 1, offer a plurality of louvres 5, described louvre 5 is circular hole, improves radiating effect.At housing 1, along the circumferential direction offer cavity 6, in one end of cavity 6, be connected with water inlet pipe 7, the other end is connected with outlet pipe 8, and described water inlet pipe 7 and outlet pipe 8 are arranged on the not homonymy of metal shell 1.By injected water in cavity 6, the heat that inductor is come out is taken away by water, more constantly passes into recirculated water, reuses.By employing, set up louvre and the method that passes into recirculated water, 45 ℃ of script iron core temperature rises can be reduced to 25 ℃, script coil temperature rise is 65 ℃ and is reduced to 45 ℃.
Described iron core 1 adopts Ferrite Material to make, and can reduce the density of iron core, delays the wearing and tearing of metal winding.
Described metal winding 3 adopts Copper Foil coil winding to become, and the width of Copper Foil is 44mm, and thickness is 0.3mm.The window utilance of Copper Foil coil is high, has magnetic flux distribution in coil window, and low price, is convenient to promote the use of.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection range of the present utility model.
