Description

Technical Field

[0001] This utility model relates to the field of locomotive cooling system technology, and in particular to a water-cooling device for locomotive traction motors. Background Technology

[0002] Traditional diesel locomotives have been gradually replaced by electrically driven locomotives. This "oil-to-electric" conversion achieves energy conservation, emission reduction, lower operating costs, and improved locomotive performance and efficiency. As the core component of the locomotive's traction system, the traction motor is mostly cooled by forced air cooling using a traction fan and flexible air ducts. While this method has advantages such as simple structure, light weight, low cost, and strong environmental adaptability, its heat dissipation efficiency is low and its cooling capacity is limited.

[0003] Therefore, there is an urgent need for a water-cooling device for locomotive traction motors that can effectively cool and dissipate heat, in order to solve the problems in the existing technology. Utility Model Content

[0022] The embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0023] refer to Figure 1A water-cooling device for locomotive traction motors includes a cooling device 1, a water pump 2, and a water-cooling circuit 3. The cooling device 1 is located at the bottom of the locomotive. The traction motors 5 on the locomotive include multiple sets symmetrically arranged on both sides of the cooling device 1. The input end of the traction motor is connected to the output end of the cooling device via a pipeline, and the output end of the traction motor is connected to the input end of the cooling device via a pipeline, forming the water-cooling circuit 3. The water pump 2 is installed on the water-cooling circuit 3. Through the symmetrical arrangement of the traction motors and the water-cooling circuit, one cooling device can simultaneously cool four traction motors, and the water-cooling method results in high cooling efficiency.

[0024] refer to Figure 2 The cooling device 1 is suspended from the bottom of the locomotive by a crossbeam 4 in a pre-reserved C-shaped groove, and the crossbeam 4 is connected to the C-shaped groove by bolts. Preferably, four sets of M16 bolts are used.

See also Figure 1 The arrows indicate the direction of cooling water circulation in the water-cooled circuit. The water-cooled circuit starts from the cooling device, is pumped out by the water pump, and then splits into four circuits that connect to the four sets of traction motors. After heat exchange by the traction motors, the water is collected in the cooling device through pipelines. The cooling device dissipates heat from the high-temperature cooling water through cooling fans and radiators, thus realizing water-cooled circulation and improving the cooling efficiency of the traction motors.
