The invention discloses a
cooling tower shared by multiple systems of an
electric locomotive. The
cooling tower comprises three cooling systems, namely a
traction transformer cooling
system, a traction
current transformer cooling
system and a
train power supply cabinet cooling
system, and specifically comprises a top air feeding box, a middle box body, two-column axial flow fan, an air filtering device, a three-runner double-flow-path heat dissipater, a bottom bearing framework, a water pump, an expansion water tank, a water pipeline, an auxiliary
oil tank, an oil pipeline, an electric connector and a gas
relay. By the adoption of an integrated complementary design method, the
traction transformer, the traction
current transformer and the
train power supply cabinet cooling system are integrated in the same
cooling tower; on the premise of simultaneously meeting the requirement on the heat dissipation of the
traction transformer, the traction
current transformer and the
train power supply cabinet, the cooling
tower disclosed by the invention has the advantages of compact structure,
high heat dissipation performance, light weight, small volume, low auxiliary
power consumption,
low noise, convenient use and maintenance, high reliability and the like.
