Thermal test hardware for liquid cooling. Built in the U.S.
Yuuki thermal test vehicles reproduce the heat and hotspots of a high-power AI or defense chip at precise, repeatable levels. Measure how well a cold plate performs without risking a real GPU.

TTV v1 is designed for about 1.2 kW, with independently controlled heater zones and embedded thermocouples.
Built for the teams who design and qualify cold plates
- Cold-plate and liquid-cooling makersQualify new designs against realistic chip heat loads.
- Metal 3D-printing companiesProve your printed parts perform, with data you can publish.
- University thermal labsRun repeatable chip-cooling experiments without buying GPUs.
- Server makers and test labsValidate cooling before hardware reaches the rack.
- Defense electronics teamsCool radar, electronic-warfare and directed-energy systems with a domestic supplier.
Cooling hardware for a cleaner grid
Data centers are on track to more than double their electricity use by 2030. Solar inverters, grid batteries and EV power electronics have to shed heat too. Yuuki builds US thermal hardware that helps all of them waste less energy.
- Less energy spent on coolingCold plates that remove heat more effectively let data centers run warmer coolant, lean less on chillers and use less pumping power.
- Thermal hardware for solar and storageInverters, battery storage and EV power electronics need reliable cooling to last. We're extending our test and cooling hardware to them.
- A domestic clean-energy supply chainMost solar hardware is manufactured overseas today. We're building thermal parts in the U.S. for U.S. solar, storage and electrification projects.

Send us your cold plate design. Get a thermal report back, free.
We're opening a limited number of founding slots. Share your design under NDA and we'll model it against a realistic chip power map. When our test rig is live, founding partners get priority bench testing.
What you send
- Your cold-plate CAD file, under NDA
- Coolant, flow rate and inlet temperature
- The chip or power map you're designing for
What you get back
- Thermal resistance across your flow range
- Pressure drop at each flow rate
- Hotspot temperatures on the power map
- A report you're free to use in your own marketing
Yuuki TTV v1
A copper die simulator that behaves like a high-power AI chip, so every cold-plate test starts from the same known heat load.
| Heat load | About 1.2 kW, sized for current AI accelerators |
|---|---|
| Heater zones | Independently controlled, to reproduce a real chip's hotspot pattern |
| Temperature sensing | 6 to 10 embedded thermocouples for temperature mapping |
| Mounting | Standard interface, so you can bolt on your own cold plate |
| Software | Runs test sequences and calculates thermal resistance automatically |
| Safety | Thermal cutoffs and complete documentation |
| Made in | United States |

Where Yuuki is headed
Test hardware comes first. It builds our customer relationships and gives us the rig to prove our own cold plates.
- Now Thermal test vehicles TTV v1, our own test rig and the first founding customers.
- Next Complete flow-loop kit A ready-to-run test loop with pump, sensors and software.
- In research Gyroid-lattice cold plates 3D-printed cold plates for radar, electronic-warfare and directed-energy electronics. Performance not yet validated.
- Later Cold plates for AI data centers Bringing proven designs to the largest liquid-cooling market.
- Longer term Clean-energy thermal hardware Cooling and test hardware for solar inverters, battery storage and EV power electronics.
