[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 loud noise

Abstract
The invention discloses a cooling tower shared by multiple systems of an electric locomotive, comprising three cooling systems in total, a traction transformer cooling system, a traction converter cooling system, and a train power supply cabinet cooling system, specifically including a top air intake box, a middle box body, a double Axial flow fan, air filter device, three-channel double-flow radiator, bottom bearing frame, water pump, expansion tank, water pipeline, auxiliary oil tank, oil pipeline, electrical connector, gas relay and other components. The present invention adopts the overall matching design method, and the traction transformer, traction converter, and train power supply cabinet cooling system are integrated in the same cooling tower, and on the premise of meeting the heat dissipation requirements of the traction transformer, traction converter, and train power supply cabinet at the same time, it has It has the advantages of compact structure, strong heat dissipation, light weight, small size, low auxiliary power consumption, low noise, convenient use and maintenance, and high reliability.
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.
