Direct air cooling of outdoor electronic cabinets
First Claim
1. A method for cooling a cabinet comprising the steps of forcing circulating ambient filtered air into, through and outwardly from the cabinet and in direct contact with heat producing components within the cabinet, monitoring the relative humidity within the cabinet and, in response to the monitored relative humidity exceeding a maximum percentage value above which water caused damage of the components occurs, decreasing the rate of flow of air into the cabinet for causing heating of the air for reducing the relative humidity of the air to below said maximum percentage value.

Abstract
Outdoor, electronic component containing cabinets are cooled by forced circulation of outside air through the cabinet for direct, cooling contact with the components. The incoming air is filtered, heated as necessary to evaporate water droplets in the air prior to entry of the air into the component containing portions of the cabinet, and the air flow is regulated for slowing the flow rate of the air within the cabinet as is necessary for maintaining the relative humidity within the cabinet below a maximum percentage; typically 40%.
