AI Technical Summary
Existing rugged chassis, with their fully enclosed design, struggle to meet both heat dissipation requirements and performance indicators such as electromagnetic interference, humidity, and salt spray. Conventional forced air cooling designs require ventilation holes, which leads to substandard performance.
It adopts a fully enclosed design, with an internal air-cooled heat dissipation chamber and a closed chassis chamber. It uses an external fan and staggered air ducts for forced air cooling to ensure the airtightness and efficient heat dissipation of the chassis.
It achieves efficient heat dissipation in a fully enclosed state, avoiding leakage of electromagnetic, humid heat, salt spray and other conditions, and maintaining the airtightness and electrical performance of the chassis.
