Description

Technical Field

[0001] This utility model relates to a cooling system for rail vehicles, specifically to a quick-detachable filter installation structure, a cooling system, and a vehicle. Background Technology

[0002] Rail transit equipment typically includes heat-generating components such as transformers. These components are often installed at the bottom of the vehicle body. During operation, the transportation equipment raises dust, iron filings, moisture, willow catkins, or other impurities, resulting in poor air quality in the cooling system of these heat-generating components. Without filtration, this can lead to problems such as heat exchanger blockage, reduced cooling power, and excessive temperature rise in the heat-generating components. Therefore, it is necessary to add filters to the heat exchangers to improve filtration efficiency, extend the cleaning cycle of the heat exchangers, and reduce workload.

[0003] With the acceleration of urbanization and the increase in population mobility both domestically and internationally, low-speed intercity EMUs have ushered in a period of rapid development. However, the bottom of low-speed EMUs generally lacks a floor plate or is designed with a non-sealed floor plate, resulting in poorer cooling air intake quality for heat-generating components such as transformers. Although filters are installed, the filters still need to be disassembled and the heat exchangers cleaned regularly.

[0004] Existing cooling system filter removal structure, such as Figure 1 As shown, filter screen 6 is fixed to the cooler or filter by several bolts on its frame. Disassembly requires removing all bolts around the filter screen, a complex, time-consuming, and labor-intensive process. Furthermore, due to the high frequency of disassembly, bolts may strip, affecting the efficiency of filter screen removal. Utility Model Content

[0030] Please see Figure 1 - Figure 4An embodiment of the cooling system with a quick-release filter screen of this utility model includes a heat exchanger 5, a mounting frame 3 and a filter screen 6. The mounting frame 3 is installed at the air inlet of the heat exchanger 5, and the filter screen 6 is installed inside the mounting frame 3.

[0031] The mounting frame 3 includes an upper plate 31, a lower plate 32, and two side plates 33. The upper plate 31 is provided with an upper sliding groove 34, and the lower plate 32 is provided with a lower sliding groove 35. The upper sliding groove 34 and the lower sliding groove 35 are arranged opposite to each other. The two side plates 33 are arranged opposite to each other, and the two ends of the two side plates 33 are welded to the two ends of the upper plate 31 and the lower plate 32, respectively.

[0032] The filter screen 6 is provided with a top edge 61 that matches the upper sliding groove 34, a bottom edge 62 that matches the lower sliding groove 35, and two oppositely arranged side edges 63.

[0033] To enable quick disassembly and installation, at least one notch 36 is provided on the upper sliding groove 34 of the mounting frame 3, and at least one fixing block 1 is provided on the top edge 61 of the filter screen 6. The length of the fixing block 1 is less than or equal to the length of the notch 36. When the filter screen 6 is installed in the mounting frame 3, the fixing block 1 interferes with the upper sliding groove 34. When the filter screen 6 is disassembled, the fixing block 1 is aligned with the notch 36, and the filter screen 6 can be pulled outward with external force to be removed from the upper sliding groove 34. Figure 5 , Figure 6 As shown.

[0034] To facilitate the removal of the filter screen 6 from the mounting frame 3, a handle 7 is provided on the outside of the filter screen 6.

[0035] To fix the filter screen 6, mounting holes are provided on the side plate 33 of the mounting frame 3, and connecting ears 2 are provided on one side edge 63 of the filter screen 6. When the filter screen 6 is installed, the connecting ears 2 are connected and fixed to the mounting holes by quick-release bolts 4.

[0036] To save operating space at the front end of the cooling system, the upper slide groove 34 and the lower slide groove 35 are arranged laterally along the cooling system, so that the filter screen 6 can be removed laterally from the cooling system.

[0037] To improve the filtration effect, at least two filter screens 6 are installed side by side in the mounting frame 3, and adjacent filter screens 6 are separated by reinforcing ribs.

[0038] Installation principle description of this utility model:

[0039] The connecting ear 2 on the filter screen 6 is fixed to the side plate 33 of the mounting frame 3 by quick-release bolts 4.

[0040] The lower end of the filter screen 6 is engaged in the lower sliding groove 35, and the upper end is engaged in the upper sliding groove 34. The movement of the filter screen 6 perpendicular to the direction of the upper sliding groove 34 is restricted by the interference between the fixing block 1 and the fixing block 1. Since only one side 63 of the filter screen 6 is connected to the side plate 33 of the mounting frame 3 via the connecting ear 2, the filter screen 6 can only slide towards the side where the connecting ear is located. This aligns the fixing block 1 on the filter screen 6 with the notch 36 on the upper sliding groove 34. Pulling the handle 7 outwards will tilt the filter screen 6 outwards at a certain angle. Then, lifting the handle 7 will remove the filter screen 6. Figure 5 , Figure 6 As shown.
