Abstract:
An air flow cooling system for an electrical chassis, said system comprising:an electrical chassis comprising side, front and rear panels; an upper horizontal plate spanning side-to-side and front-to-back within said chassis; a lower horizontal plate spanning side-to-side and front-to-back within said chassis; a mid-located backplane spanning side-to-side and from the bottom face of said upper horizontal plate and from the top face of said lower horizontal plate; said front and side panels, said upper horizontal plate, said lower horizontal plate, and said mid-located backplane forming a front thermal zone within said chassis; said rear and side panels, said upper horizontal plate, said lower horizontal plate, and said mid-located backplane forming a rear thermal zone within said chassis; said front and rear thermal zones not in direct communication with each other; ventilation means forcing air flow through said front and rear thermal zones; and front and rear thermal zone air filters, said air flow flowing through said air filters before flowing through said front and rear thermal zones; said front and rear thermal zone air filters and said ventilation means governing separate air flow volumes through said thermal zones.
