Outdoor enclosure with heated desiccant

摘要

A protective enclosure for housing heat-generating electronics, having a sorption device for controlling humidity and a heater for heating the sorption device. The invention protects electronics placed within the enclosure from the effects of water vapor and condensation during normal operation and in the event of power loss. The sorption device adsorbs water vapor during normal operation or power loss when the temperature in the enclosure falls below the dew point. The sorption device releases collected water as water vapor when power is restored and the temperature in the enclosure rises above the dew point. The invention thereby prevents failure of the electronics due to condensation build-up and provides for effective long-term use of the sorption device.
