Description

Technical Field

[0002] With the increasing requirements for energy conservation, consumption reduction and environmental protection of rail transportation equipment, how to use running air to cool the traction equipment of locomotives and vehicles has become a technical research direction of common concern for main engine manufacturers and cooling system suppliers.

[0003] At present, locomotive and EMU traction transformers and traction converters generally use a forced ventilation liquid cooling system. A fan unit is arranged in front of or behind the radiator to force cooling air into the radiator core to exchange heat with the high-temperature medium for heat dissipation, so that the fan unit of the forced ventilation liquid cooling system is always in operation.

[0004] Therefore, in existing forced-air liquid cooling systems, fans are the sole source of cooling air. While these fans provide high flow rates, they also present issues such as high noise and high energy consumption. Radiator structural design is crucial for addressing these issues by fully utilizing the circulating airflow to reduce the fan's air volume and pressure requirements, thereby reducing noise and energy consumption.

[0005] Therefore, there is an urgent need for a radiator for a locomotive cooling system that can improve heat dissipation effect, reduce noise and energy consumption, so as to solve the problems existing in the prior art. Utility Model Content

[0029] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0030] Example:

[0031] A radiator for a locomotive cooling system, reference Figures 1-2 , including a top cover 1, a heat dissipation pipe 2 and a bottom cover 3; the top cover 1 is arranged above the bottom cover 3 and the heat dissipation pipes 2 are evenly distributed between the top cover 1 and the bottom cover 3; the heat dissipation pipe 2 is provided with a liquid inlet 2.1 and a liquid outlet 2.2 at both ends, the liquid inlet 2.1 is connected to the outlet of the locomotive cooling system, and the liquid outlet 2.2 is connected to the inlet of the locomotive cooling system; the bottom cover 3 is fixed on the locomotive, and an air duct 4 is provided between the bottom cover 3 and the locomotive. Figure 1 The middle arrow indicates the wind direction, and the horizontal arrow indicates the running wind and ambient wind passing through the air duct. In this embodiment, a heat dissipation pipe is provided between the top cover and the bottom cover, and an air duct is provided under the bottom cover. The running wind of the locomotive and the ambient wind are used to dissipate heat from the heat dissipation pipe, thereby assisting the cooling system in dissipating heat, saving energy, improving the heat dissipation efficiency, reducing the load on the cooling system, and thus also helping to reduce the noise of the cooling system.

[0032] refer to Figure 3 and Figure 5 The top cover 1 and bottom cover 3 each include a top plate and side plates connected to either side of the top plate. The side plates of the bottom cover 3 are also connected to the locomotive. The top plate, side plates, and locomotive in the bottom cover 3 enclose the air duct 4 to form the air duct. The cross-section of the air duct 4 formed by the top plate, side plates, and locomotive is trapezoidal. The air duct 4 is arranged along the direction of travel of the locomotive. In this embodiment, the top plate and side plates of the top and bottom covers are integrally formed, forming a matching top and bottom cover by the top plate and side plates, thereby facilitating the formation of an air duct between the bottom cover and the locomotive body.

[0033] In this embodiment, the air duct is set to be trapezoidal, which is beneficial to improving the stability of the radiator and increasing the heat dissipation area of ​​the air duct.

[0034] Heat sinks 5 are further provided above the top cover 1 and below the bottom cover 3 , and the heat sinks 5 are arranged along the traveling direction of the locomotive.

[0035] By arranging a plurality of heat sinks above the top cover and below the bottom cover, and placing the heat sinks vertically along the direction of the locomotive, the heat dissipation area of ​​the radiator and the ambient wind and running wind is increased, further improving the heat dissipation effect.

[0036] refer to Figure 4 The heat pipes 2 are evenly distributed in a "F" shape between the top cover 1 and the bottom cover 3. These heat pipes 2 are square copper tubes, connected to the cooling system via a liquid inlet 2.1 and a liquid outlet 2.2 at each end. Using directional copper tubes ensures a close fit between the top and bottom covers, increasing the heat transfer area.

[0037] A sealing frame 6 is provided at the edge between the top cover 1 and the bottom cover 3. The sealing frame includes a longitudinal frame 6.1 and a transverse frame 6.2, which is used to seal the gap between the top cover and the bottom cover to prevent sand and gravel from entering and damaging the radiator when the locomotive is running.

[0038] Both the top cover 1 and bottom cover 3 are provided with fixing holes 7 corresponding to the mounting holes on the locomotive, for securing the top cover 1 and bottom cover 3 to the locomotive. The provision of several fixing holes on both sides of the top and bottom covers, and alignment of the fixing holes and the fixing holes with the mounting holes on the locomotive, facilitates the radiator's secure installation on the locomotive, preferably on the locomotive's roof.

[0039] The top cover 1 and the bottom cover 3 are also provided with heat dissipation holes 8, which are located between two adjacent heat sinks 5. By providing a plurality of heat dissipation holes on the top cover and the bottom cover between the two heat sinks, the heat dissipation holes of the top cover and the bottom cover are aligned one by one, so that the air volume of the fan is increased from bottom to top and the heat dissipation holes are passed through, so as to further dissipate heat to the top cover and the bottom cover. Figure 1 The arrow from bottom to top indicates the wind direction of the fan.

[0040] When the liquid medium that needs to be cooled flows into the liquid inlet of the heat dissipation pipe, the heat dissipation pipe will transfer the heat to the top cover and bottom cover through the temperature of the liquid in the square copper tube. If the locomotive runs at a fast speed or the ambient temperature is low, the heat dissipation requirements can be met only by the running wind and ambient wind, and there is no need to start the fan under the radiator, achieving the effect of green, low carbon, energy saving and emission reduction; if the locomotive runs at a slow speed or the radiator does not dissipate enough heat, the fan under the radiator will be started to achieve the purpose of simultaneous heat dissipation by the fan, ambient wind and running wind. At the same time, the required fan power is greatly reduced.

[0041] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
