ALVC Vapor Chamber

Name: ALVC Vapor Chamber
Brand: ALVC Europe

High-efficiency two-phase aluminum vapor chambers. Isotropic heat spreading with 5,000–10,000 W/mK effective thermal conductivity — up to 70% lighter than copper.

The ALVC Aluminum Vapor Chamber (AVC) is built on an advanced flat aluminum heat pipe structure (Micro-Port Extrusion MPE), delivering exceptional two-phase heat spreading efficiency even under high power density conditions. Designed to eliminate hotspots and enhance device reliability and service life.

The fully integrated monolithic aluminum construction of the ALVC system is created using Friction Stir Welding (FSW). This advanced solid-state joining process plastifies the material to form a seamless, metallurgical bond without melting. This eliminates the need for failure-prone end caps, guaranteeing absolute zero leakage risk, maximum mechanical stability, and exceptional corrosion resistance even in demanding environments.

Working Principle

Heat Absorption at Evaporator: The heat source (e.g. GPU, IGBT) transfers heat to the evaporator zone of the MPE aluminum structure. The internal working fluid vaporizes, generating vapor at low internal pressure.
Vapor Spreading Across the Full Surface: The vapor spreads laterally through micro-port extrusion channels in all directions. Heat is distributed uniformly across the entire base area — hotspots are eliminated.
Condensation at Condenser: The vapor condenses at the cooler condenser zone (fin structure or heatsink) and releases heat to the environment. The condensate is returned to the evaporator zone.
Closed Loop — 100% Passive: Friction Stir Welding (FSW) seals the system hermetically without end caps. The loop runs permanently without a pump, without power, and without wear — with a service life exceeding 100,000 operating hours.
