Description

Technical Field

[0001] This utility model relates to a high-power integrated cooling system for new energy mining trucks, belonging to the field of new energy mining truck technology. Background Technology

[0002] Light-duty mining dump trucks are one of the key pieces of equipment in earthmoving construction and open-pit mines. With the popularization of new energy technologies, more and more electrical components are being installed on these vehicles, resulting in a huge demand for heat dissipation. Mining trucks face special working conditions in mines, such as significant differences in weight between fully loaded and empty vehicles, and large differences in power requirements between heavily loaded uphill and empty downhill sections. This leads to greater demands for heat dissipation in terms of both power and braking capacity. How to dissipate excess energy directly affects the driver's experience and even driving safety.

[0003] In existing products, the cooling requirements of systems such as the powertrain, electrical system, and braking system vary. Each system typically has its own independent cooling system designed according to its own heat dissipation needs. To ensure heat dissipation efficiency, the heat dissipation power and component selection of each subsystem are often designed based on extreme operating conditions. However, each system will not be under extreme operating conditions simultaneously, resulting in a large cumulative design redundancy, which affects the overall vehicle economy and performance. When arranging the cooling system in the vehicle, the layout of the existing products is often determined based on the location of each system within the vehicle. However, due to different layout requirements, the placement of each subcomponent of the cooling system is relatively scattered, which increases the difficulty of laying out liquid cooling pipes and wiring harnesses, as well as the difficulty of maintenance. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a high-power integrated cooling system. By combining the heat dissipation requirements of the vehicle's powertrain and electrical systems, and considering the extreme operating conditions of each system, the total heat dissipation power required by the entire vehicle is comprehensively calculated, resulting in a cooling system that better meets the vehicle's needs. Simultaneously, all sub-components required by the cooling system, such as the cooling modules, expansion tank, DC / DC power supply module, wiring harness assembly, and water pump, are centrally arranged. Based on the requirements of each system for inlet water temperature, flow rate, and pressure, the pipeline branches and routes are rationally planned, significantly reducing the space occupied by the cooling system within the vehicle. Furthermore, the integrated cooling system can be assembled through separate wiring, thereby improving the overall vehicle assembly efficiency.
