Water Cooling Plate Heat Sink

Superior Liquid Thermal Performance: Liquid cooling plates dissipate high heat fluxes efficiently by transferring heat via fluid channels, not air.

High-Conductivity Aluminum Alloy: Constructed from 6000-series aluminum (e.g., 6061/6063) for effective thermal transfer and structural stability.

Customizable Internal Flow Paths: Incorporates serpentine, micro-channel, or manifold liquid channels to optimize heat absorption and pressure drop.

Compact, Low-Profile Design: Flat form-factor enables integration into compact systems such as EV batteries, power modules, or high-performance electronics.

Robust Sealing and Leak Resistance: Manufactured via vacuum brazing, friction stir welding, or controlled-atmosphere brazing for reliable coolant containment.

Low Weight and High Integration: Lightweight aluminum construction integrates directly into assemblies, reducing thermal interface complexity.

Modular and Scalable: Plate sizing and port configuration support design scalability from small electronics to multi-kW energy systems.
