Description

Technical Field

[0001] This invention relates to the field of adjustable locomotive air duct structure technology for use in center beam load bearing, and in particular to an adjustable locomotive air duct structure for use in center beam load bearing. Background Technology

[0002] Due to the spatial constraints of the locomotive, a single fan is typically used to ventilate and cool several pieces of equipment, utilizing the internal cavities of the frame to create ventilation ducts. These ducts consist of one inlet and several outlets. The inlet connects to the fan, while the outlets connect to the equipment requiring ventilation and cooling. However, the frame also bears the load, and its internal cavities contain partitions to reinforce its strength and rigidity. These partitions, however, divide the ductwork into several chambers. Turbulence near these partitions affects the air pressure and volume within the duct. Because each outlet is located at a different distance from the inlet and passes through different partitions, the air pressure and volume attenuation vary, making it difficult to guarantee that the air pressure and volume at each outlet meet design requirements. Summary of the Invention

[0003] To overcome the shortcomings of existing systems, this invention provides an adjustable locomotive air duct structure for use in the load-bearing of the central beam.
