Liquid Cold Plate (LCP)
Custom Liquid Cold Plates (LCP). We master all manufacturing types and advise you on the most efficient solution for your project.
ALVC offers the full spectrum of direct liquid cooling (Liquid Cold Plates). Whether for large-scale BESS storage, high-density AI data centers, or robust industrial inverters – we deliver the exact right cooling solution.
Since we master all modern LCP manufacturing processes (see list below) in-house, we provide completely technology-independent consulting. Together, we identify the most thermally and commercially efficient architecture for your project – from prototyping in Stuttgart to global mass production.

LCP Manufacturing Variants
Friction Stir Welding (FSW)
For high volume and IGBT modules. Hybrid technology of CNC and welding. Absolutely leak-proof and flexible channel design.
Vacuum Brazing
Complex, intricate internal cooling structures. Multiple layers possible. Ideal for high-end computing (HPC) and aerospace.
Skived Fin
Extremely fine fins for very large surfaces in minimal space. Cost-effective, no thermal resistance between base and fin.
Embedded Tube
Pressed-in copper or stainless steel tubes in an aluminum base plate. Very cost-efficient and established for moderate heat loads.
Gun-Drilled
Deep-hole drilled aluminum plates. Very robust, withstands extremely high pressures. Somewhat limited channel routing.
Technology
