ALVC NORDWAND: Passive Two-Phase Cooling Wall for IGBT & SiC Inverters (12 kW, -37 K)

From 122 °C down to 85 °C (-37 K) under 12.0 kW total thermal load across six high-power IGBT modules, combined with isothermal surface spreading across a 900 mm mounting plane in under 10 seconds (ΔT ≈ 2 K) at 0 W pump power: With the ALVC NORDWAND series, ALVC Europe GmbH replaces solid metal baseplates and maintenance-heavy liquid loops with a structural two-phase aluminum cooling wall.

In industrial drives, traction converters, and Battery Energy Storage Systems (BESS), rising semiconductor power densities push solid aluminum or copper mounting plates past their spreading-resistance limits. Heat concentrates directly beneath the modules while outer fin sections remain underutilized, often forcing a premature shift to pumps, hoses, quick-disconnect couplings, and a 20-year coolant maintenance schedule.

Steady-State (12.0 kW / -37 K) & Transient IR Thermal Benchmarks

• Steady-State 12.0 kW Benchmark (-37 K): 85 °C peak module temperature with ALVC NORDWAND versus 122 °C on an identical-envelope solid aluminum heatsink across 6× high-power IGBT modules.
• +44% Thermal Power Reserve: At the same 85 °C temperature ceiling, the identical cabinet footprint rejects 12,000 W instead of 8,360 W purely passively into the cooling airstream.
• Transient IR Spreading Under 10 s: Across the 900 mm eight-module IGBT mounting wall, internal vapor transport equalizes load steps to ΔT ≈ 2 K surface uniformity within seconds.
• Hermetic Solid-State Joining: Extruded multi-channel ALVC Aluminum Vapor Chamber profile permanently sealed via solid-state Friction Stir Welding and 100% inline helium leak tested.
• Zero-Maintenance Inverter Backplane (0 W): 0 W parasitic pump power, 0 hoses, 0 quick-disconnect couplings, and full fin effectiveness across the entire rear heat-sink wall.

Scalable Multi-Module Footprints, Cabinet Integration & Series Production

Engineered as a load-bearing mounting backplane, ALVC NORDWAND scales seamlessly across 6-module, 8-module, or custom IGBT and SiC inverter arrays inside IP54/IP65 enclosures. Engineers can pre-size their own boundary conditions in the ALVC Co-Engineering Studio or submit 3D STEP envelopes to our engineering team in Stuttgart (service@alvceurope.com) for DFM review, functional prototyping, and serial production.
