Ventilation panels are used for low-cost commercial purposes, such as computer network equipment, Internet systems, high-performance data servers, civil communication equipment, etc., with low cost, moderate electromagnetic interference shielding effectiveness and excellent ventilation performance. The conventional honeycomb aperture is 3.18mm (i.e. 1/8 of the imperial system, the hexagonal side length is 1.83mm), the hole depth is 12.7mm, and the aluminum alloy shielded ventilation board with different surface treatment has different electromagnetic shielding effectiveness.
It is an aluminum frame made of two parallel layers of aluminum honeycomb assembled in a pultruded aluminum alloy profile through mechanical assembly, and each layer of honeycomb is oriented to each other at 90°, which greatly improves the shielding performance, thereby eliminating the polarization characteristics of the honeycomb structure. The conventional honeycomb aperture is 3.18mm (i.e. 1/8 of the imperial system, the hexagonal side length is 1.83mm), the hole depth is 6.35mm, and the total thickness is 12.7mm. The double-layer construction can improve shielding performance without the need for tin or nickel plating.
The vent of the ventilation waveguide plate is one of the main leakage parts of electromagnetic interference, and the conventional method of opening a small hole in the chassis board or adding metal mesh has not reached the desired level in the past. In accordance with the requirements of national military standards, a series of honeycomb shielded ventilation board products have been developed, and the contradiction between ventilation and shielding is solved by using the principle of cut-off waveguide.
Aluminum honeycomb ventilation panels include single-layer honeycomb ventilation panels and double-layer honeycomb ventilation panels.
The ventilation plate is made of high-quality aluminum alloy honeycomb and pultruded aluminum alloy profiles made of aluminum frame through mechanical assembly, honeycomb ventilation plate has good electromagnetic shielding and ventilation performance, the ventilation area can reach 95%, light weight. The product has been equipped with high-quality conductive gaskets, which are used for electromagnetic shielding and environmental sealing of the gap between the interface between the Axicomb series shielded ventilation plate and the mechanical installation of the chassis, which can be directly installed by the user and is extremely convenient for operation and maintenance.
