Title:
VEHICLE-USE TRANSFORMER
Document Type and Number:
WIPO Patent Application WO/2017/068873
Kind Code:
A1
Abstract:
Provided is a vehicle-use transformer, wherein the transformer is effectively cooled by a traveling wind due to the reduction in an overlap of a traveling wind intake position of the transformer with respect to a stagnation area behind a peripheral apparatus in the rear of the vehicle advancement direction. This vehicle-use transformer 10a is provided with the following: a transformer body 12 that has a winding 9 and is connected to a tubing 11 in which a refrigerant circulates; an oil pump 13 for circulating the refrigerant to the tubing 11; coolers 14a that connect to the tubing 11 and cool the refrigerant; and a first duct that has a first air intake port for taking in a traveling wind generated by the travel of the vehicle, a first air supply port for supplying the traveling wind toward the coolers as a cooling wind, and a first coupling section that couples the first air intake port and the first air supply port together, guides the traveling wind so that an air supply direction is opposite to a vehicle advancement direction, and causes the guided traveling wind to be discharged from the first air supply port as the cooling wind, the first duct being provided to the rear in the vehicle advancement direction relative to the transformer body 12 and the coolers 14a.
