Abstract

The invention relates to a top-mounted water cooling device for a power distributed type diesel multiple unit. The top-mounted water cooling device comprises a supporting frame, air filter devices, water radiators, an expansion water tank, fan sets, a top protection net, water pipelines and the like. All the components are integrated on the supporting frame and arranged at the top of a body of the diesel multiple unit. The water cooling device can be used for replacing a water cooling device which is adopted in the prior art and arranged below a general frame; on the premise of meeting the heat exchange requirement, the contamination degree of the cooling device is lowered, use and maintenance are more convenient, the maintenance period is prolonged, and the maintenance workload is reduced; and the use and maintenance cost of operation units can be effectively reduced, and economic benefits can be improved. After top mounting is adopted, the overall mounting and layout of the diesel multiple unit are optimized, so that a new cooling technology is provided for application of the diesel multiple unit through the characteristic.

Description

technical field [0001] The invention relates to the field of heat exchange for traction power of a diesel train set, in particular to a top-mounted water cooling device for a power-distributed diesel train set. Background technique [0002] Diesel multiple units have the characteristics of large passenger capacity, low energy consumption, safety and reliability, good ride comfort, flexible marshalling, and low operating costs. It has achieved rapid development and is favored by railway transportation and urban rail transportation all over the world. Diesel engines are generally used as power for diesel multiple units, which are mainly used for intercity transportation on non-electrified railways. [0003] The power distributed EMU is the most common EMU at home and abroad. The cooling device is an important part of the traction power package of the internal combustion EMU. The water cooling device cools the high-temperature water of the diesel engine to ensure that the dies...
