Want to know the reason why the brazed Liquid Cold Plates can:

Reduce more temperature
Achieve uniform cooling

Our commitments

The performance of liquid cold plates varies greatly depending on the flow path and the accuracy of the contact surface with the heat source even if the material and pump capacity are the same.

Uniform Cooling

Since the coolant flowing inside the plate absorbs the device's heat, the surface temperature varies around the inlet and the outlet.
It is important to design an effective liquid flow path to reduce the fluctuation of surface temperature.
Surface flatness Accuracy

The surface flatness less than 0.02mm
Brazing technology

Brazing the entire surface of the lid and body without a gap

Characteristics

Material	Body	C1020 (oxygen-free copper)
Material	Mouthpiece	SUS
The maximum size		800L × 450W
Flatness		0.02mm or less (cooling section)
Parallelism		0.02mm or less (cooling section)
Surface treatment		Ni plating

Using C1020 (Oxygen-free copper)

Oxygen-free copper can be used even in vacuum apparatus because its gas release is minimal.

Ni plating on the surface

We recommend Ni plating to protect the cooling performance from oxide and prevent further corrosion on the surface.

Brazing by the vacuum or atmosphere furnace

We use our brazing technology to join the main body side & the lid, and the body & the fitting. This process is highly reliable and environment-friendly as it does not use flux.

Recommended coolant

Pure water (managed by ion exchange unit)
Industrial water, tap water (neutral, requires management of pH)
Antifreeze (with rust inhibitor)
Ethylene glycol + pure water
Propylene glycol + pure water

* If you have any questions about Chillers, Teflon tube or grease, please feel free to contact us.

Design

If you inform us of the dimensions and heat load of your device, we design and suggest an appropriate type of a liquid cold plate to meet your specific requirements.

Fitting connection

We recommend stainless steel fittings, which have high corrosion resistance and heat resistance.
As stainless steel fittings are joined with copper or aluminum plates by our advanced brazing technology, we guarantee the reliable and long-term use of our products.

Benefits of copper material

High thermal conductivity

The thermal conductivity of copper (398W · m^-1 · k^-1) is the second to highest, following silver (420W · m^-1 · k^-1), twice that of aluminum (236W · m^-1 · k^-1), and 20 times higher than that of stainless steel (16.7W · m^-1 · k^-1). Therefore, copper is suitable for liquid cold plates.
