Wireless base station-having cooling passages
First Claim
1. A wireless base station for outdoor use comprising a housing having a front wall and a passive heat control comprising a heat conductive upwardly extending vertical rear wall, and an upwardly extending forward air flow passage interconnected for air circulation at upper and lower positions to an upwardly extending rearward air flow passage defined partly by the rear wall, and at least one circuit pack extending upwardly within the housing and having electronic components which extend into the forward air flow passage and in operation, generate heat and heat the forward air flow passage whereby heat circulates between the forward and rearward air flow passages to distribute heat and maintain desired operating temperatures of the electronic components, the air being heated flowing upwards in the forward air flow passage and downwards in the rearward air flow passage as heat is transferred to the rear wall.

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.
