HGLaser unveils the Power Battery Liquid Cooling Plate Laser Automated Welding Intelligent Equipment, delivering a disruptive breakthrough in the manufacturing of core components for new energy vehicles.
As a key component of the thermal management system for power batteries, the welding quality of the liquid cooling plate directly impacts the safety, range, and lifespan of new energy vehicles.
With the rapid rise in EV adoption, explosive growth in the energy storage sector, and surging demand for liquid cooling in data centers, the traditional brazing process—characterized by high energy consumption, high material waste, and heavy pollution—can no longer meet industry needs.
Laser welding has emerged as the key breakthrough, but not without its own set of challenges:
Five Major Challenges in Laser Welding:
High reflectivity of aluminum: Low energy utilization, prone to pores and cracks.
Difficult-to-penetrate oxide layer: Large melting point differences lead to poor weld quality.
Microchannels require full sealing: 0.1 mm gap tolerance—any leakage means failure.
Severe deformation during high-speed welding: Flatness requirement ≤ 0.5 mm/m².
Ultra-long weld seams: Push the limits of welding head durability.
HGLaser’s newly launched Power Battery Liquid Cooling Plate Laser Automated Welding Intelligent Equipment takes laser beam energy regulation as the core welding technique and integrates optical design, materials science, and intelligent control to achieve groundbreaking innovation.
