Outdoor Enclosure Electronics Protection Technical Report

1. Problem Background

In outdoor environments, electronic control boards are susceptible to moisture, rain, and temperature variations, which can lead to corrosion. Even if the enclosure uses rubber seals at both ends, practical tests show that temperature changes can still allow water vapor to enter.

Causes:

1. Temperature differences cause internal pressure fluctuations (positive/negative), drawing in external moisture.
