Title:
LIQUID-COOLED ELECTRIC POWER CONVERSION DEVICE AND RAILWAY VEHICLE
Document Type and Number:
WIPO Patent Application WO/2013/046492
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a liquid-cooled electric power conversion device for a railway vehicle, the liquid-cooled electric power conversion device being configured so that an increase in temperature within the device is suppressed and so that soiling within the device is prevented. A liquid-cooled electric power conversion device is provided with: an electric power conversion device (1) and a cooling device (100) which are provided within the engine compartment (201) of a railway vehicle (200); semiconductor elements (2) and an electric component (13) which are provided within the electric power conversion device (1); a third heat exchanger (5) which is located between the electric component (13) and an electric air blower (12); a cooling body (4) to which the semiconductor elements (2) are mounted; a first heat exchanger (111b) which is provided within the cooling device (100); a second heat exchanger (111a) which is provided within the cooling device and which is smaller than the first heat exchanger (111b); piping (7a) which connects the third heat exchanger (5) and the second heat exchanger (111a); and piping (7b) which connects the cooling body (4) and the first heat exchanger (111b).
