AI Technical Summary

Technical Problem

Existing heat dissipation control boxes in the nuclear power field require ventilation openings due to the use of forced cooling by fans, resulting in poor waterproofing and susceptibility to dust and corrosive gases, posing safety hazards.

Method used

The staggered ventilation holes with a double-layer protective structure, combined with a sealing structure and fan assembly, enhance the airtightness of the enclosure and accelerate heat dissipation through reverse airflow, reducing moisture intrusion.

Benefits of technology

While ensuring good heat dissipation, it significantly improves waterproof and protective performance, reduces the ingress of water vapor and dust, and lowers the risk of equipment failure.
