Description
Technical Field
The invention belongs to a ventilation device, and particularly relates to a shielding ventilation device for an outdoor equipment cabinet.
Background
With the continuous development of science and technology, the integration level of electronic equipment is higher and higher, the power is higher and higher, and the electromagnetic environment is worse and worse.
The outdoor cabinet is used as a main carrier of the electronic equipment, the risk of electromagnetic interference of other equipment is faced, meanwhile, the electromagnetic radiation generated by the internal equipment affects the other equipment, and the use reliability of the equipment is seriously affected by the shielding performance of the equipment. In addition, because of the heat dissipation and outdoor operation requirement of equipment, outdoor rack needs to be equipped with the vent, needs to satisfy rain-proof requirement simultaneously.
Traditional outdoor shutter electromagnetic shield performance is relatively poor, and current electromagnetic shield ventilation window does not possess rain-proof ability.
Disclosure of Invention
The invention provides the outdoor cabinet for solving the ventilation and heat dissipation problems and improving the electromagnetic compatibility of equipment.
The invention relates to a shielding ventilation device for an outdoor equipment cabinet, which has the following technical scheme that the shielding ventilation device comprises an installation outer frame, wherein ventilation holes are formed in the outer frame, an electromagnetic shielding window is connected in the installation outer frame, and the electromagnetic shielding window is a four-fold rectangular waveguide structure array.
Preferably, the four-folded rectangular waveguide structure has a bending angle of 120 °.
Further, a dust filtering net is arranged at the outer side of the installation outer frame,
further, the dust filtering net is connected with the installation outer frame through screws.
Further, a groove is formed around the mounting outer frame, and a conductive sealing gasket is mounted in the groove.
Further, the conductive gasket is flush with the mounting surface of the mounting housing after the shield ventilation device is mounted.
Compared with the prior art, the invention provides a ventilating device which is used for outdoor electronic equipment and has rainproof and electromagnetic shielding functions. The electromagnetic shielding window is a plurality of rectangular wave guide, so that electromagnetic waves are greatly attenuated when passing through the shielding window, each rectangular wave guide is of a four-fold structure, wind resistance is low, ventilation effect is good, and meanwhile raindrops can be effectively prevented from flowing into equipment.

Description of the embodiments
The technical scheme of the invention is further explained below with reference to the attached drawings.
Referring to fig. 1, 2 and 3, the shielding and ventilating device for an outdoor equipment cabinet of the present invention is composed of a conductive sealing pad 1, an electromagnetic shielding window 2, an installation outer frame 3 and a dust filtering net 4.
Fig. 2 shows an electromagnetic shielding window 2, which is the most main component of the present invention, and is formed by an array of rectangular waveguides 21 in a four-fold structure, wherein the bending angle of the four-fold rectangular waveguide 21 is 120 °. The electromagnetic shielding window has better rainproof, ventilation and shielding effects, is embedded into the installation outer frame 3 and is connected with the installation outer frame through brazing.
Fig. 3 shows a mounting frame 3, on which a groove 31 and a vent 32 are provided, the groove is used for mounting the conductive gasket 1, and the shielding and ventilation device is compressed to be flush with the mounting surface of the mounting frame after being mounted, so that the compression amount of the conductive gasket is ensured. The ventilation area of the installation outer frame is smaller than that of the electromagnetic shielding window 2, a threaded hole is formed in the back face of the installation outer frame, and the dust filtering net 4 is installed on the back face of the installation outer frame through screws.
According to the ventilating device, the electromagnetic shielding window generates great attenuation when electromagnetic waves pass through the shielding window, meanwhile, the structure is low in wind resistance and good in ventilating effect, meanwhile, raindrops can be effectively prevented from flowing into equipment, and the ventilating device is particularly suitable for ventilating outdoor large-sized electronic equipment.
