Abstract: Presented herein is a corrosion inhibitor dispensing system that provides for the in-situ application of a corrosion inhibitor in order to protect internal elements of an apparatus from corrosion. In one example, an apparatus is provided that may include a housing to contain one or more electronic components. The housing includes air inflow ports configured to limit internal air from exiting the housing during a corrosion inhibitor dispensing processes, air outflow ports configured to limit external air from entering the housing during the dispensing process, and one or more fans to direct airflow for the housing. The apparatus further includes a corrosion inhibitor dispensing system that includes a dispensing container to hold a corrosion inhibitor in a non-vaporized state and includes one or more ports for dispensing the corrosion inhibitor in a vaporized state during the corrosion inhibitor dispensing processes. A controller is provided to manage the dispensing process.
