POWER CONVERSION DEVICE FOR RAILWAY VEHICLE

Title:

POWER CONVERSION DEVICE FOR RAILWAY VEHICLE

Document Type and Number:

WIPO Patent Application WO/2020/137133

Kind Code:

A1

Abstract:

In a case where a plurality of heat generating bodies are disposed within a single wind tunnel mounted below a floor of a railway vehicle, when heat calculation is performed for the entire interior of the wind tunnel in a state in which each of the heat generating bodies is generating the maximum amount of heat, the design will have a large margin resulting in the amount of heat generated being estimated to be higher than the actual amount, which leads to larger sizes for mounted equipment and cooling mechanisms. In order to avoid the foregoing, provided is a power conversion device rigged below the floor of a vehicle in order to drive an electric motor used by a railway vehicle. The equipment that forms the power conversion device and that is associated with heat generation is housed in a storage space through which cooling air flows, and equipment with a different maximum heat generation period is disposed in series with respect to the flow of the cooling air.
