In this study, a far-off local zone telecommunication infrastructure container ventilation system with cabinets is modelled. CFD analysis is performed to obtain the temperature and velocity profile inside the container with given heat loads and volume flow rates provided by fans. In the second part of the study, performance improvement scenarios are simulated. Hot regions are found at the back sides of the cabinets and vortices are formed in the middle plane zone of the volume which reduces the air intake of the fans in corresponding cabinets inside the container. To overcome this issue, a flow director, i.e. vortex breaker is designed to redirect to enhance fan suction, and the orientation of the cabinets have rearranged. According to the results, it is possible to improve the ventilation performance of a container with such an approach. In this study, %2.0735 of improvement is achieved by changing the location of the cabinets and placing a vortex breaker inside the room, where it is a significant change for such far-off local zone telecom applications, considering the extreme environmental conditions.
