Our CNC Machined Leak-Proof EV Battery Water Cooling Plate is a premium thermal management solution specifically engineered for the demanding cooling requirements of modern electric vehicle battery systems. It integrates advanced manufacturing and precision engineering to ensure optimal, long-term performance and reliability.

Crafted from high-grade aluminum alloy, the core of this plate is formed by high-precision CNC machining, which guarantees exceptionally accurate and consistent internal cooling channels. This process is complemented by expert forming and welding techniques to create a completely sealed, monolithic structure. Every single unit is validated through rigorous helium leak detection and high-pressure endurance testing, ensuring absolute leak-proof integrity under extreme thermal and pressure cycling conditions.

Key Parameters

Primary Applications

Our high-precision CNC-machined liquid cooling plate is a specialized thermal control solution developed primarily for advanced, high-power electric vehicle applications. Its key application focus is:

• Thermal Management for EV/HEV Battery Packs:​ Ensures uniform temperature control for lithium-ion battery modules, enhancing safety, performance, and cycle life.

Key Advantages:

• Precision CNC-Machined Channels:​ The use of CNC machining allows for the creation of complex, optimized flow paths with tight tolerances. This ensures perfect coolant distribution across the entire plate surface, eliminating thermal gradients and maximizing heat transfer efficiency from the battery cells.
• Guaranteed Leak-Proof Design:​ The combination of precision-machined components and robust welding/brazing creates a hermetic seal. Our 100% helium leak test certification provides unequivocal assurance against coolant leakage, a critical safety factor for vehicle battery systems.
• Superior Heat Transfer Performance:​ The direct metal contact and custom-designed channel geometry facilitate rapid heat absorption from the battery and efficient transfer to the coolant, which is essential for supporting fast charging and sustained high-power discharge.
• Lightweight & Structurally Sound:​ Manufactured from aluminum, it provides an excellent strength-to-weight ratio. The design is engineered for the vibration and mechanical stresses of automotive environments while minimizing added vehicle mass.
• Fully Customizable Solutions:​ We offer complete design flexibility. Dimensions, port locations, channel patterns, and flow configurations can be tailored to integrate seamlessly with your specific battery pack layout and thermal load profile.

Our CNC-machined cooling plates are the ideal solution for passenger EVs, commercial electric vehicles, and specialty electric mobility applications, where reliability, safety, and thermal performance are non-negotiable. We provide comprehensive support from initial concept design and prototyping through to volume production and dedicated technical service.
