Abstract

The invention provides a high-power cooling tower of a rapid power concentration motor train unit. The high-power cooling tower comprises a top cover, a rack, a cooling fan, a heat exchanger, a base,a shield pump, an expansion water tank, an oil pipeline, a water pipeline, a relay and an online detection device, wherein the top cover, the rack, the heat exchanger and the base sequentially form anair cooling channel of the cooling tower from top to bottom; the cooling fan is arranged in the rack, and the shield pump, the expansion water tank and the relay are arranged on the side wall of therack. A water inlet cavity of the heat exchanger is connected with a water outlet pipe of a traction converter, a water outlet cavity of the heat exchanger is connected with a water inlet pipe of theshield pump, a water outlet pipe of the shield pump is connected with a water inlet pipe of the traction converter, and the oil pipeline is connected with a traction transformer. The cooling tower issimple in structure, light in weight, convenient to maintain, low in noise, intelligent and capable of synchronously cooling the traction converter and the traction transformer.

Description

technical field [0001] The invention relates to the technical field of cooling devices for vehicles, in particular to a high-power cooling tower for high-speed power concentrated EMUs. Background technique [0002] With the rapid development of domestic rail transit, especially for the integration and reliability of centralized power EMUs, extremely high requirements are put forward, including the performance and reliability requirements for traction converters and traction transformers. Main equipment for traction converter and traction transformer cooling. Centralized power EMUs are more compact in structure and have higher requirements for structural design. However, in the design of cooling towers at home and abroad, there are still complex structures, numerous auxiliary structures, low space utilization, inconvenient installation and disassembly, and high noise. Constantly monitor the operating status of components, effectively prevent system failures, and high mainten...
