PROBLEM TO BE SOLVED: To provide a travel wind cooling device for rolling stock having a cooling system to miniaturize the outer size of a power converter as a heating source and to improve cooling performance. SOLUTION: A circulating cooling system utilizing a forcible heat transportation system for receiving generated heat of an element by using a coolant and performing a heat transportation of the generated heat to a heat radiating part via a pipe by power of a pump is constructed. Namely, this device has a heat receiving part provided with a passage to circulate the coolant, the heat radiating part 7 provided in a flow passage in which travel wind flows, and the flow passage for circulating the coolant between the heat radiating part and the heat receiving part. The flow passage in which the travel wind flows is provided to be recessed in an inside direction of a vehicle body from an underfloor cover 10 continuously provided on the surface of the vehicle body on an underfloor part of the vehicle body.
