A cooling system (10) comprises a fan (26) in a fan duct (14), a housing (12), electrical components (38), an air intake (22), an air outlet (24;25), and a cooling passage (20). The housing (12) is mounted on the exterior of the fan duct (26). The electrical components (38) are mounted on interior sides of the housing (12), for cooling. The cooling passage (20) is located inside the sides of the housing (12) on which the electrical components (38) are mounted. The air intake (22) draws air into the cooling passage (20) from a region of the fan duct (14) downstream of the fan (26). This air passes through the cooling passage (20), cooling the electrical components (38) while remaining fluidly isolated from the interior of the housing (12). Air from the cooling passage (20) is released by the air outlet (24;25) into the environment, or into a region of the fan duct (14) upstream of the fan (26). |
