What Is a Liquid Cold Plate?
How Does Liquid Cold Plate Cooling Work for High-Power Electronics?
A liquid cold plate is a metal heat exchanger — typically copper or aluminum — with precision-machined internal flow channels through which coolant circulates to absorb heat from high-power components such as CPUs, GPUs, IGBTs, and EV battery cells. ToneCooling manufactures custom liquid cold plates with thermal resistance as low as 0.0136°C/W, handling heat flux exceeding 200 W/cm².
As AI computing scales — from NVIDIA GB200 GPUs generating 1,200W+ per chip to EV battery packs drawing hundreds of kilowatts — air cooling has reached its thermal limits. Single-phase liquid cooling through precision cold plates is now the dominant solution for data centers, power electronics, and electric vehicles.
ToneCooling is a custom liquid cold plate manufacturer providing complete engineering support from CFD thermal simulation through FSW welding, vacuum brazing, and full production validation. Our process complies with ISO 9001 and references ASHRAE data center thermal guidelines.
