AI Technical Summary
Existing VPX chassis have poor sealing performance in dusty environments, allowing dust to easily enter the chassis and cause short circuits, thus failing to meet dust prevention requirements.
The VPX chassis is divided into functional space and board space by partition components. Ventilation components are used to form independent first and second air ducts. Air is drawn in through the second air duct and exhausted through the first air duct, preventing dust from directly entering the board slots and electronic component areas.
It improves the dustproof performance of the chassis, prevents dust from entering the chassis, protects electronic equipment, and ensures circuit safety.
