Case Study: Computer Server Cabinets Requires Multiple EMI Shielding Vents
A manufacturer of commercial electronics required vents in two locations on an OEM cabinet enclosure. Both vents required high air-flow and mid-level EMI shielding. A unique requirement for this application was the frame complexity required to properly made with the customer’s chassis.
•Achieve shielding of 40-50 dB
•Unique frame complexity
•Highly custom gasket configurations
KEY CUSTOMER REQUIREMENTS
•Two vent locations
•Good EMI shielding
•High air flow
•Engineering design and support
Parker Chomerics designed a STREAMSHIELDTM style frame featuring a single layer of 1/8” cell aluminium honeycomb which allowed for airflow to be maximised.
A second layer was not necessary to meet shielding requirements. A full frame, with EMI gasket and honeycomb media was proposed as a single assembly. This allowed Parker Chomerics to add custom reliefs in the metal frame to properly mate to the customer’s chassis, as well as offer the customer a single part number to meet their requirements.
Parker Chomerics’ experienced CAD designers were able to work with the customer’s chassis models and come up with a STREAMSHIELD vent frame with 1/8in cell aluminium honeycomb with an EMI gasket.
Without this internal engineering effort and experts, Chomerics would not have been able to successfully design the customised frame and offer the value added, framed assembly as one easy to order part number.
