TRACTION MODULE OF RAILWAY VEHICLE WITH COOLING DEVICE, METHOD OF OPERATION OF SUCH MODULE AND RAILWAY VEHICLE Russian patent published in 2020 - IPC B61C11/00 B60H1/00 

FIELD: transport machine building.

SUBSTANCE: invention relates to traction module (10) of railway vehicle. Traction module comprises electrical equipment elements (16, 17, 18) and cooling device (20). Cooling device (20) comprises first and second fluid circuits, crossing respectively first (38, 39) and second (40) heat exchange regions with said electrical equipment elements, as well as first (34) and second (36) heat exchangers, crossed respectively by said first (54) and second (60) fluid circuits and providing heat exchange between said fluid and first airflow (32). Fluid medium circuits have first common pipeline (70, 71, 54) for circulation of fluid medium, which crosses first heat exchanger (34) and then is divided into parallel continuing second (60) and third (62) pipelines, wherein second conduit (60), being part of second fluid circuit, at first crosses second heat exchanger (36), and then second heat exchange area (40).

EFFECT: adjustment of cooling of electrical components of the traction module.
