AI Technical Summary
Existing frequency converter cabinets have poor noise reduction and sound insulation effects, and noise can easily spread outward through gaps or openings, resulting in limited practicality.
It adopts a multi-layer structure design, including sound insulation panels, sound insulation felt, sound-absorbing cotton and vibration damping mounting brackets, combined with sawtooth ventilation channels and rubber vibration damping pads, to enhance sound wave reflection attenuation and vibration noise absorption.
It significantly reduces noise transmission, ensures heat dissipation efficiency, improves sound insulation and equipment stability, and enhances practicality.
