Helium Leak Tested Brazed Aluminum Liquid Cooling Plate For Industrial Applications

Introduction:

Our Helium Leak Tested Brazed Aluminum Liquid Cooling Plate is a robust and reliable thermal management solution engineered for demanding industrial and high-power applications. It combines precision stamping, advanced vacuum brazing, and certified leak testing to deliver superior cooling performance and structural integrity for critical systems.

Manufactured from high-grade aluminum, the core of this plate utilizes advanced stamping technology to form high-efficiency micro-channel flow paths. Multiple stamped components are then fused into a single, monolithic unit through a high-temperature vacuum brazing process, creating a durable, permanently sealed assembly. Every production unit is validated with 100% helium leak testing, guaranteeing absolute integrity against coolant leakage under extreme pressure and thermal cycling conditions. The design also features customizable threaded ports for reliable, secure system connections.

This high-performance brazed cooling plate is designed for high-capacity battery systems that prioritize safety and reliability. Its primary applications are:

• Thermal Management for Prismatic Cell Battery Packs:​ Optimized for direct cooling of large-format prismatic cells (e.g., 280Ah, 314Ah) used in Electric Vehicle (EV) and Battery Energy Storage System (ESS) applications. It ensures even temperature distribution across the cell's large surface area, which is critical for cycle life and safety.

• Certified Leak-Proof Reliability:​ Every cooling plate undergoes mandatory 100% helium mass spectrometry leak testing, certifying its leak-proof integrity. This provides the highest level of assurance against coolant ingress, protecting sensitive battery systems in industrial and automotive environments.

• Durable, Monolithic Construction:​ The vacuum brazing process creates metallurgical bonds stronger than the base material, resulting in a single-piece, rigid structure that is exceptionally resistant to vibration, shock, and thermal stress, ensuring long-term operational reliability.

• Efficient Stamped Micro-Channels:​ Precision-stamped flow channels optimize the heat transfer surface area and coolant flow dynamics, ensuring efficient heat extraction from the battery cells. This design manages the high thermal loads of large prismatic cells effectively.

• Integrated, Customizable Ports:​ Features customizable threaded (e.g., NPT, BSPP) or flanged ports, providing robust, leak-tight interfaces for quick and reliable integration with coolant hoses and system piping, simplifying installation and maintenance.

• Scalable, Application-Specific Design:​ The stamped and brazed manufacturing process is highly scalable. We can tailor the plate's overall dimensions, channel pattern, and port specifications to fit the exact footprint and thermal requirements of your specific cell (e.g., 280Ah, 314Ah) and battery pack design.

Our helium leak-tested, brazed aluminum cooling plates are the trusted solution for industrial cooling, high-capacity ESS, and heavy-duty EV battery packs where leak prevention, durability, and precise thermal control are paramount. We offer comprehensive support, from concept design and thermal simulation to high-volume, quality-assured production.
