Embodiment Construction

[0026] Below, the present invention will be further described in conjunction with the accompanying drawings and specific embodiments.

[0027] A shielding-enhanced waveguide ventilation window includes one or more waveguide shielding layers, the main body of the waveguide shielding layer is a shielding plate 6, and the shielding plate is provided with a plurality of cut-off waveguide ventilation holes 7; the cut-off waveguide ventilation holes There is an included angle between the axis and the surface of the shielding plate.

[0028] Further, multiple waveguide shielding layers are stacked, and adjacent waveguide shielding layers are mirror-symmetrical.

[0029] Further, the cross-sectional shapes of the cut-off waveguide ventilation holes include regular hexagons, circles and quadrilaterals.

[0030] Further, a dust-proof net or a sealing cover is also included, and the dust-proof net or the sealing cover is closely attached to the waveguide shielding layer.

[0031] Furth...

Abstract

The invention discloses a shielding enhanced waveguide ventilation window, and belongs to the technical field of electromagnetic compatibility shielding. The waveguide ventilation window comprises oneor more waveguide shielding layers, a shielding plate serves as a body of each waveguide shielding layer, and multiple cut-off waveguide ventilation holes are formed in each shielding plate; and an included angle is formed between the axis of each cut-off waveguide vent hole and the surface of the corresponding shielding plate. In addition, a dustproof net or a sealing cover can be additionally arranged, so that the waveguide window has dustproof and sealing functions. The shielding enhanced waveguide ventilation window is especially suitable for a shielding body which has limited waveguide window thickness, is quite harsh in use environment and requires dust prevention and rain prevention.

Description

technical field [0001] The invention relates to the technical field of electromagnetic compatibility shielding, in particular to a shielding-enhanced waveguide ventilation window. Background technique [0002] With the development of technology, the complexity and integration of military industrial systems are getting higher and higher, and the functions are becoming more and more powerful, and the electromagnetic compatibility problems brought along with it have gradually attracted people's attention. As one of the commonly used electromagnetic shielding devices, the waveguide ventilation window uses the principle of waveguide high-pass filtering to shield electromagnetic waves, passing electromagnetic waves higher than the cutoff frequency and attenuating electromagnetic waves lower than the cutoff frequency. The waveguide ventilation window can realize the electromagnetic shielding function under the premise of meeting the ventilation and heat dissipation requirements of ...
