The utility model discloses to dispel the heat combines with the shielding, both can realize that the heat dissipation also can realize the shielding.
Description
Technical field
This utility model relates to a kind of heat radiation shielding construction for circulator.
Background technology
Circulator is the incidence wave by entering its either port, according to the multiport device of the direction incoming next port of order determined by quiet bias field.It is bigger that existing circulator has magnetic dispersion, magnetic circuit is inefficient, and external magnetic field is relatively big on the impact of circulator electrical property, and the magnetic susceptibility components and parts around circulator are subject to the impact in circulator magnetic field, the energy of permanent magnet only has the shortcomings such as small part concentrates in circulator, and capacity usage ratio is relatively low.Circulator is operated under high-peak power, except electrical specifications and frame for movement, it is also contemplated that heat radiation factor, otherwise when power is higher, the heat that circulator loss produces does not distribute not go out, so that the temperature rise of ferrite gyromagnet sheet has exceeded its ability to bear, device performance will severe exacerbation, affect the service life of device, at present, adopt more in circulator, set heat abstractor, increase the structure size of circulator, make circulator outward appearance overall volume become big, not only increase cost, and affect between circulator and other device integrated.
Application number be 201220186061.8 utility model disclose a kind of circulator with shielding construction, application number be 201220186057.1 utility model disclose a kind of circulator with radiator structure.But prior art does not have a kind of circulator structure heat radiation and shielding combined.
Utility model content
The purpose of this utility model is in that to overcome the deficiencies in the prior art, it is provided that a kind of heat radiation shielding construction for circulator, heat radiation and shielding is combined.
The purpose of this utility model is achieved through the following technical solutions: a kind of heat radiation shielding construction for circulator, and including housing, the top of housing, bottom and surrounding are separately installed with at least one barricade so that enclosure interior forms a closed magnetic circuit;Enclosure interior is provided with center conductor, at least two panels ferrite gyromagnet sheet and one or more magnetic circuit plate, and two panels ferrite gyromagnet sheet is the outer both sides being sandwiched in center conductor respectively, and two panels ferrite gyromagnet sheet is connected with case inside respectively, and hull outside sets magnetic circuit plate.
Described barricade is iron plate.
The beneficial effects of the utility model are: heat radiation and shielding are combined by this utility model, both can realize heat radiation and can also realize shielding.Reduce the external magnetic field impact on circulator electrical property;Magnetic susceptibility components and parts around protection circulator are not by the impact in circulator magnetic field;One low magnetic resistance passage is provided simultaneously, improves circulator magnetic circuit efficiency, reduce magnetic dispersion, make the energy of permanent magnet concentrate on inside circulator as far as possible so that capacity usage ratio reaches the highest.Adopting automatic heat radiation mode, it is ensured that when power is higher, the heat that circulator loss produces can distribute, and has simple in construction, it is not necessary to separately set heat abstractor, reduce cost, extends the advantage such as service life of device.

Fig. 1 is this utility model front view;
Fig. 2 is this utility model sectional view;
In figure, 1-housing, 2-center conductor, 3-ferrite gyromagnet sheet, 4-magnetic circuit plate.
Detailed description of the invention
Below in conjunction with accompanying drawing, the technical solution of the utility model is described in further detail, but protection domain of the present utility model is not limited to the following stated.
As depicted in figs. 1 and 2, a kind of heat radiation shielding construction for circulator, including housing 1, the top of housing 1, bottom and surrounding are separately installed with at least one barricade so that housing 1 is internally formed a closed magnetic circuit;Housing 1 is internally provided with center conductor 2, at least two panels ferrite gyromagnet sheet 3 and one or more magnetic circuit plate 4, two panels ferrite gyromagnet sheet 3 is the outer both sides being sandwiched in center conductor 2 respectively, two panels ferrite gyromagnet sheet 3 is connected with inside housing 1 respectively, sets magnetic circuit plate 4 outside housing 1.
Described barricade is iron plate.Described iron plate is made by the pure iron sheet Q235 material that permeability is significantly high.
In the present embodiment, housing 1 adopts metal shell, better heat-radiation effect.
Work process of the present utility model:
For radiator structure: assuming that ferrite gyromagnet sheet 3 surface temperature is TF, metal shell temperature is TM, air themperature is T0, radiating of the present utility model is: reach, by the mode of conduction of heat, the metal shell that temperature is TM in the ferrite gyromagnet sheet 3 of temperature TF, the air contact of metal shell and T0, by the mode of natural cooling, energy is passed to air, it is achieved heat radiation.
For shielding construction: whole housing 1 is internally formed a closed magnetic circuit, internal circulator electrical property will not be produced considerable influence by external magnetic field;Meanwhile, the magnetic susceptibility components and parts around protection circulator are not by the impact in circulator magnetic field.Barricade is that heat radiation can also be played a role by iron plate simultaneously.
Claims (2)
1. for a heat radiation shielding construction for circulator, including housing (1), it is characterised in that: the top of housing (1), bottom and surrounding are separately installed with at least one barricade so that housing (1) is internally formed a closed magnetic circuit;Housing (1) is internally provided with center conductor (2), at least two panels ferrite gyromagnet sheet (3) and one or more magnetic circuit plate (4), two panels ferrite gyromagnet sheet (3) is the outer both sides being sandwiched in center conductor (2) respectively, two panels ferrite gyromagnet sheet (3) is connected with housing (1) inner side respectively, and housing (1) outside sets magnetic circuit plate (4).
