Abstract
An outdoor wireless base station having a housing and a circuit pack extending upwards in the housing with electronic components extending into a forward air flow passage. The forward air flow passage is interconnected for air circulation with a rearward air flow passage and a heat conductive rear wall of the housing partly defines the rearward flow passage. Air in the forward air flow passage flows upwards and into the rearward air flow passage for heat removal through the rear wall. The cooling air flows downwards in the rearward air flow passage to return to the bottom of the forward air flow passage.
