Abstract

The invention discloses a high-speed train cooling device. The high-speed train cooling device comprises an installation framework, a water-cooling assembly and an air-cooling assembly, wherein the water-cooling assembly and the air-cooling assembly are arranged on the installation framework, the water-cooling assembly comprises a heat exchanger, an expansion water tank and a shielding water pumpwhich are sequentially connected via pipeline, a water outlet of the shielding water pump is used for communicating with a water inlet of a traction converter, a water inlet of the heat exchanger is used for communicating with a water outlet of the traction converter, the water-cooling assembly comprises a centrifugal cooling fan and a centrifugal air filter, an air inlet of the centrifugal cooling fan is arranged corresponding to the heat exchanger and is used for introducing outside air and taking away heat in the heat exchanger, and the centrifugal air filter is arranged at a windward sideof the centrifugal cooling fan. By the high-speed train cooling device, synchronous cooling of the traction converter and a reactor can be achieved, and the high-speed train cooling device is simple in structure, light in weight, good in sealing performance and low in manufacturing cost and is convenient to maintain.

Description

technical field [0001] The invention relates to the technical field of cooling devices for locomotives, in particular to a cooling device for high-speed EMUs. Background technique [0002] With the rapid development of domestic rail transit, especially for the integration and reliability of high-speed EMUs ("Harmony" high-speed trains with a speed of 200km / h and above, and some sections running at a speed of 250km / h or above), extremely high requirements have been put forward. High requirements, including performance and reliability requirements for traction converters and reactors, and the cooling device is the main equipment for the cooling of EMU converters. In the prior art, the electric locomotive adopts forced ventilation to cool the traction motor. Usually, an axial flow fan is set corresponding to several traction motors on a bogie for forced ventilation. In order to enhance the cooling effect, there is also a scheme of setting an axial flow fan corresponding to ea...
