Adsorbent system with humidity control and valve system
The granted patent (Publication Number: US11904292B2) discloses an adsorbent system designed to control humidity levels within an enclosure. The system comprises an enclosure with a cavity defining a humidity-controlled environment, a body with a channel for fluid communication between the ambient environment and the humidity-controlled environment, and an adsorbent material within the channel. The system includes a valve system at the first end of the channel, with an inlet valve biased to a closed position to regulate the flow of inlet fluid and an outlet valve biased to a closed position to control the flow of outlet fluid based on pressure differentials.
Furthermore, the system features a configuration where the inlet fluid flows over a portion of the adsorbent material along the shortest path through the channel, while the outlet fluid directly flows over the same portion of the adsorbent material along a separate path. The adsorbent material, which can be a desiccant like silica gel, zeolites, or alumina, is designed for efficient humidity control. The enclosure, which can be used in applications like vehicle headlamp assemblies or electronics enclosures, is sealed relative to the ambient environment, with periodic heat exposure for regeneration of the adsorbent material. The valve system, comprising passive valves that open based on pressure differentials, ensures effective regulation of fluid flow within the system.
