Frequently Asked Questions
Which welding method is best for IGBT cold plates?
Copper brazing offers lowest thermal resistance. Friction stir welding suits aluminum with high pressure requirements. Deep/shallow tube press-in is cost-effective for mid-range power.
Can you match our existing IGBT module footprint?
Yes. Send us your module datasheet and we will design the cold plate to match.
What coolant types are compatible?
Pure water, 25-50% EGW (standard for automotive), and dielectric fluid variants available.
Do you support NPI and low-volume prototyping?
Yes. Prototype quantities from 5-20 pcs with 2-4 week lead time.

About Igbt Liquid Cold Plate
A IGBT liquid cold plate is a precision thermal management component designed to transfer heat from high-power electronic devices to a circulating liquid coolant. Unlike air-cooled heat sinks, liquid cold plates achieve dramatically higher heat transfer coefficients — making them the standard solution for any application where heat flux exceeds 50W/cm² or where junction temperature control within ±5°C is required.
ToneCooling designs and manufactures custom IGBT liquid cold plate solutions for data centers, electric vehicles, power electronics, and industrial systems. Our engineering team supports customers from initial thermal simulation through prototype validation and volume production.

CFD Simulation: Industrial IGBT Liquid Cold Plate — 10 kW Heat Load
This simulation validates our AL6061-T6 liquid cold plate for high-power IGBT module stacks (8 modules × 1,250W = 10 kW total). Five coolant flow rates from 5 to 40 L/min were evaluated. At 20 L/min, the cold plate holds IGBT surface temperature below 62°C with a pressure drop of only 0.029 MPa — the recommended operating point balancing thermal performance and pump load. A second case study from rail transit (6-IGBT array) confirms compatibility with both pure water and 50% glycol mixtures.
