Description
Technical field
The present invention relates to a kind of foaming metal ventilating window.
Background technology
Along with the development of modern science and technology, electronic equipment has adopted digital circuit and Power Electronic Circuit in a large number, and the while is owing to the requirement of volume, so that device interior electronic devices and components integrated level is more and more higher, power density is also increasing.For this reason, have the ventilation hole so that heat radiation at cabinet.According to shielding theory, the ventilation hole size is less, and screening effectiveness is higher; And theoretical according to heat radiation, the ventilation hole size is larger, and the effect of ventilation and heat is better.Obviously both requirements to the ventilation hole size on the performance are opposite.
Existing ventilation unit is the high-pass filtering principle according to waveguide: namely the size of waveguide aperture (cross-sectional area) has determined the cut-off frequency of waveguide, to the electromagnetic wave that is higher than waveguide cutoff frequency give by, then decayed for the electromagnetic wave that is lower than waveguide cutoff frequency, attenuation depends on the length (thickness) of waveguide, thereby existing ventilation unit is made by perforated metal plate or by the regular hexagon metal honeycomb plate.Perforated metal plate is because very thin thickness, and its screening effectiveness is lower, especially at f〉in the frequency range of 1-10GHz, the shielding electromagnetic waves efficiency attenuation is only had 10-30dB, can not satisfy shielding requirements far away; Although and regular hexagon metal honeycomb plate screening effectiveness is higher, required thickness is about 13-40mm (13mm commonly used) generally, thereby is not suitable for volume (especially thickness), the strict electronic equipment of weight.According to military standard of China, ventilating part must have the antivibration requirement, reaches certain rank.Therefore, need a kind of high-performance foaming metal ventilating window that a kind of vibration resistance is strong, ventilation effect good, screening effectiveness is high.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of high-performance foaming metal ventilating window, to overcome the defective that exists in the prior art.
Technical scheme of the present invention is: a kind of foaming metal ventilating window is characterized in that: comprise left and right sides metal edge frame with reinforcement, about six side's cellular boards and Ni-based foaming metal; Wherein, about six side's cellular boards place Ni-based foaming metal both sides, six side's cellular board both sides about placing with the left and right sides metal edge frame of reinforcement, with the left and right sides metal edge frame of reinforcement with Ni-based foaming metal and about six side's cellular boards be assembled into one.
Described left and right sides metal edge frame with reinforcement by rivet with Ni-based foaming metal and about the riveted joint of six side's cellular boards assemble.
The outside of described left and right sides metal edge frame with reinforcement is pasted with the conductive fabric liner.
Described left and right sides metal edge frame with reinforcement is that aluminium sheet processes, and surface-coated is electric conductive oxidation.
Six side's cellular boards are aluminium section about described, and surface-coated is electric conductive oxidation.
Technique effect of the present invention is:
Have good ventilation effect, high screening effectiveness, high strength, lightweight advantage.

Fig. 2 is STRUCTURE DECOMPOSITION schematic diagram of the present invention.
Reference numeral is:
1-with the left and right sides metal edge frame, 2 of reinforcement-about six side's cellular boards, 3-Ni-based foaming metal, 4-rivet, 5-conductive fabric liner.
Embodiment
The invention belongs to electromagnetic compatibility shielding ventilating part technical field, a kind of high-performance foaming metal ventilating window that particularly a kind of vibration resistance is strong, ventilation effect good, screening effectiveness is high.
Referring to Fig. 1 and Fig. 2, the concrete structure of a kind of foaming metal ventilating window that the present invention relates to is:
Comprise left and right sides metal edge frame 1 with reinforcement, about six side's cellular boards 2 and Ni-based foaming metal 3; Wherein, about six side's cellular boards 2 place Ni-based foaming metal 3 both sides, six side's cellular boards, 2 both sides about placing with the left and right sides metal edge frame 1 of reinforcement, with the left and right sides metal edge frame 1 of reinforcement with Ni-based foaming metal 3 and about six side's cellular boards 2 be assembled into one.
Among the present invention with the left and right sides metal edge frame 1 of reinforcement specifically can by rivet 4 with Ni-based foaming metal 3 and about 2 riveted joints of six side's cellular boards assemble.
The outside with the left and right sides metal edge frame 1 of reinforcement among the present invention can be pasted with conductive fabric liner 5.Fit tightly so that the present invention and equipment are installed, be electrically connected around guaranteeing continuous.
Among the present invention with the left and right sides metal edge frame 1 of reinforcement for aluminium sheet processes, and surface-coated is electric conductive oxidation.Left and right sides metal edge frame 1 with reinforcement will increase the cross reinforcement accordingly according to size, to increase vibration resistance, frame intensity is strengthened, and adhesive force is stronger.Placing rivet 4 positions also has principle so that with the left and right sides metal edge frame 1 of reinforcement with about six side's cellular boards 2, Ni-based foaming metal 3 fit tightly, increase vibration resistance.
Six side's cellular boards 2 are aluminium section about among the present invention, and surface-coated is electric conductive oxidation.Ni-based foaming metal 3 foaming density are very low, cause this kind base material itself almost not have rigidity, and when vibration, the Ni-based foaming metal 3 of six side's cellular boards, 2 supports comes restrained deformation about must relying on.About this six side's cellular boards about in the of 2 adhesive force more intense, can effectively protect Ni-based foaming metal 3 materials not to be destroyed, be difficult for weighing wounded Ni-based foaming metal 3.
Ni-based foaming metal 3 among the present invention is the foaming metal base materials such as the nickel with a large amount of stacked micropores made through special process, iron.Ni-based foaming metal 3 has good ventilation effect and screening effectiveness, is preferably material of combination property.
