Considering to use Aluminum Type liquid plate,
But worried about corrosion?

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

Vacuum and flux brazing

Brazing technology joins the main body & the lid, and the body & the fitting. This process is well-known for its high reliability.
When conducting flux brazing under a vacuum condition, the gas release can cause problems. For customers who do not want gas in their chamber, we can implement vacuum brazing instead of flux brazing.

Aluminum Brazing Technology

To braze the base material without melting it, we use an alloy that has a lower melting point than the base material to be brazed.
Though the melting point of aluminum (A1050) is about 650 °C, the brazing filler metal is also based on aluminum, so there is almost no difference.
Therefore, it is crucial to control the temperature inside the furnace delicately.

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

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 Aluminum material

1. Cost reduction

Raw material costs approximately three times less compared to Copper.
2. Lightweight

Specific gravity is about 3 times less than Copper.
Aluminum: 2.7,
copper: 8.9.

Laboratory
