Abstract
In a power conversion apparatus, at least one intra-casing cooling passage is a passage through which a coolant for cooling at least a power converter flows, and is arranged in a casing. At least one extra-casing cooling passage communicates with the at least one intra-casing cooling passage and is drawn out from an inside of the casing. The at least one extra-casing cooling passage is disposed not to be in contact to the outer periphery of the casing. The power converter is arranged to be cooled by the coolant flowing through the at least one intra-casing cooling passage, and a heat exchanger and the casing are arranged to be subjected to cooling air, resulting in the heat exchanger and the casing being cooled by the cooling air.
