Abstract
The utility model discloses a kind of multilayer ventilation waveguide window, comprise waveguide window frame and square silk screen plate, described square silk screen plate is welded on the central authorities of waveguide window frame, square silk screen plate is offered several square through-holes.The utility model adopts stainless steel, and bonding strength is far away higher than wicking formula waveguide window, and transport assembling process can not affect its quality, guarantees the shield effectiveness in each frequency range.
Description
Technical field
The utility model relates to a kind of waveguide window in electromagnetic shielding field, specifically a kind of multilayer ventilation waveguide window being applicable to MR shielded enclosure.
Background technology
Ventilation waveguide window is the important component part of shielded enclosure, and its function is the ventilation problem solving shielded enclosure, namely when ensureing the equal screening effectiveness with shielded enclosure, meets the requirement of HVAC ventilation or heat radiation.
Existing ventilation waveguide window has following shortcoming:
1. existing ventilation waveguide window adopts cellular mesh, and air resistance coefficient is large, and mesh easily blocks;
2. existing ventilation waveguide window passes through formed in mould single cellular bar in advance by metallic plate itemize, load in frame by this honeycomb bar multiple again, integral braze-welded composition waveguide window, manufacturing process is many, and required precision is high, cost is high, there is corrosion hidden danger, reliability is low, after the vibrations that are hit, affect screening effectiveness, affect useful life;
3. existing ventilation waveguide window adopts brass material or galvanized steel plain sheet mostly, and the brass ventilation waveguide window time is long, and outer surface can produce with air and be oxidized reflection and can turn black, and be that galvanized steel plain sheet can produce corrosion at outer surface by it, iron rust particle can be brought into room by ventilation.
Summary of the invention
The utility model proposes a kind of multilayer ventilation waveguide window, this design reduces air resistance coefficient, adds effective draught area, improves shield effectiveness.
The utility model is achieved by the following technical solution: a kind of multilayer ventilation waveguide window, comprise waveguide window frame and square silk screen plate, square silk screen plate is welded on the central authorities of waveguide window frame, square silk screen plate is offered several square through-holes.
Further, the quantity of described square silk screen plate is at least 3 layers, and square silk screen plate superposes setting in waveguide window frame, is connected between adjacent two layers square silk screen plate by the carriage being arranged on its surrounding.
Further, described waveguide window frame is quadrangle.
Further, described waveguide window frame and square silk screen plate all adopt stainless steel.
Further, described square silk screen plate adopts high conductive material to weld with the junction of waveguide window frame.
The utility model compared to existing technology, has following beneficial effect:
1. the utility model adopts stainless steel, and bonding strength is far away higher than wicking formula waveguide window, and transport assembling process can not affect its quality, guarantees the shield effectiveness in each frequency range.
2. the welding material that the utility model adopts is high conductive material, and screening effectiveness is fabulous.
3. the utility model adopts stainless steel argon arc welding technology, and weld can not melt because of the thermal impact of welding and snap.
