The cooling duct is designed to cool certain components of the electric drive system. The cooling duct is designed to keep certain components of the electric drive system clean.
Air is pulled into the cooling duct from the front of inverter cabinet (A) . Air is pulled through inverter cabinet (A) into duct (B) . Air is pulled through duct (B) into blower fan (C) . Air is pushed out of blower fan (C) into duct (D) .
Duct (D) is divided in order to provide pressurized air flow in three different directions. Air flows through two hoses (E) to the generator. Air that is flowing through two hoses (E) is used to cool the generator. Air flows through hose (F) . Air that is flowing through hose (F) is used to pressurize inverter cabinet (A) . Air flow continues through duct (D) . Air flow that continues through duct (D) is pushed through duct (G) .
Air flow is divided in three different directions inside duct (G) . Air flows through duct (H) to the oil coolers for the final drives. Air flows through hose (J) to the left-hand traction motor. Air that is flowing through hose (J) is used in order to cool the left-hand traction motor. Air flows through hose (K) to the right-hand traction motor. Air that is flowing through hose (K) is used in order to cool the right-hand traction motor.
Air flows through the right-hand traction motor and the left-hand traction motor. Air then flows out of the rear of housing (L) .
