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 targets that are reviewed against heat load, coolant, flow rate, pressure drop, envelope, material, and validation requirements.
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 liquid cooling solutions provider specializing in custom cold plates, cooling distribution units, and thermal management systems for data centers, AI/HPC servers, EV battery packs, and power electronics. Since 2004, our ISO 9001-certified manufacturing has shipped over 1,000,000 cold plates annually to OEM and data center customers worldwide.
