Description

Technical Field

[0001] This utility model relates to a battery and its chassis, specifically to a lithium battery chassis adapted to high-rate heat dissipation. Background Technology

[0002] As the core protective and load-bearing structure of lithium battery packs, the lithium battery enclosure primarily provides physical protection, environmental isolation, and a safe operating space for the batteries. Made of high-strength aluminum alloy or engineering plastics, it can withstand damage from external forces such as impact, vibration, and compression. Simultaneously, its sealed design prevents dust and moisture corrosion, extending battery cycle life. The optimized internal structure integrates a thermal management system and electrical insulation layers, effectively balancing temperature, preventing short circuits, and supporting the orderly arrangement of multiple series and parallel battery packs, improving energy density and space utilization. The modular design of the lithium battery enclosure facilitates installation and maintenance, adapting to different scenario requirements. Its quantitative structure reduces the overall load, making it particularly suitable for mobile devices and new energy vehicles. Standardized interfaces and compact dimensions simplify system integration, contributing to the efficient and stable operation of lithium batteries in energy storage, power tools, and other fields, making it an indispensable key component in new energy applications.

[0003] In the prior art, patent number 202321011598.5 describes a horizontally stacked lithium battery chassis. One side of the chassis main frame is provided with an L-shaped side door, a push-to-open mechanism, a push-to-open protrusion, a handle, and a hinge. The L-shaped side door is rotatably mounted to the chassis main frame via the hinge. The handle is mounted to the chassis main frame. The push-to-open mechanism is fixed to the chassis main frame. The push-to-open protrusion is mounted on the L-shaped side door, and its position coincides with that of the push-to-open mechanism. This horizontal stacking method, where the upper plug-in end is inserted along the lower end of the adjacent chassis main frame, provides high safety and convenience.

[0004] Although existing lithium battery enclosures can utilize horizontal stacking in parallel, offering high safety and convenience, they also suffer from inefficient heat dissipation within the enclosure. Utility Model Content
