Custom Aluminum Liquid Cold Plates

Aluminum Liquid Plates from LiquidPlates are precision-engineered liquid cooling solutions that combine excellent thermal performance with lightweight construction. Utilizing advanced manufacturing techniques including friction stir welding, vacuum brazing, and precision CNC machining, these cold plates efficiently transfer heat from high-power components to circulating coolant. The aluminum construction offers an optimal balance of thermal conductivity, weight, and cost for a broad range of applications. Available in standard configurations or fully customized to your specifications, our aluminum liquid plates provide reliable, leak-free cooling for demanding environments.

How It Works

Aluminum liquid plates function by conducting heat from mounted components through the aluminum base into internal coolant channels. The channel design—whether serpentine, parallel, or custom geometry—is optimized using computational fluid dynamics (CFD) to maximize heat transfer while managing pressure drop. Coolant enters through inlet fittings, flows through the engineered channel network where it absorbs thermal energy, then exits through outlet fittings to an external heat rejection system. The high thermal conductivity of aluminum (approximately 205 W/m·K) ensures rapid heat spreading from component contact areas into the liquid paths. Channel geometry creates turbulent flow conditions that enhance convective heat transfer coefficients. Surface area inside channels is maximized through features like pins, fins, or microchannel arrays depending on performance requirements. Vacuum brazing or friction stir welding joins plate halves into a leak-free assembly capable of withstanding repeated thermal cycling and high coolant pressures.
