Cooling tower shared by multiple systems of electric locomotive

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of heat exchange, in particular to a cooling tower shared by electric locomotive traction transformers, traction converters and train power supply cabinets, that is, a multi-system cooling tower for electric locomotives. Background technique [0002] At present, in the existing cooling technology for passenger electric locomotives, one electric locomotive uses two identical cooling devices to dissipate heat for the traction transformer, traction converter, and train power supply cabinet. Since the two sets of cooling devices are distributed, each cooling device requires The independent fan unit, radiator, load-bearing support frame, water pump, expansion tank, auxiliary oil tank, water system pipeline, oil system pipeline and other components are not compact in structure, occupying a large total volume of locomotive space, heavy total weight, and total auxiliary power High consumption and high noise.
