Description

Technical Field

[0001] This utility model relates to a new energy dual-axle mining truck and its water-cooled unit installation structure, belonging to the technical field of new energy dual-axle mining trucks. Background Technology

[0002] Currently, new energy dual-axle mining trucks are increasingly used in the mining transportation sector. As the "heart" of these trucks, the power battery is extremely sensitive to temperature, making it crucial for the water-cooled unit to maintain its optimal operating temperature. However, the current installation structure of the water-cooled unit in new energy dual-axle mining trucks presents some pressing issues that need to be addressed.

[0003] 1) The installation structure is not suitable for the layout of new energy dual-axle mining trucks: The overall spatial layout of new energy dual-axle mining trucks differs from that of traditional mining trucks due to the differences in motors, batteries, and electronic controls. The existing water-cooled unit installation structure simply follows the traditional mining truck model, without fully considering the positional relationships of various components in new energy mining trucks, resulting in unreasonable installation positions and affecting the maintenance and upkeep of the water-cooled unit and other components.

[0004] 2) Insufficient strength of the installation structure and cracking of welds at stress concentration points: The new energy dual-axle mining truck has a large demand for battery heat dissipation. Generally, a single unit cannot meet the system requirements, and multiple units are usually required to combine. Therefore, the weight is relatively heavy. At the same time, the road conditions in the mining area are poor, and the whole vehicle vibrates a lot, which leads to cracking of welds at stress concentration points in the installation structure of some water-cooled units.
