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

  • Reduce more temperature
  • Achieve uniform cooling

What is a liquid cold plate?

Liquid cold plates, also known as water/liquid-cooled heat sinks, are the most efficient method of heat removal. By circulating a liquid coolant through its internal channels, it absorbs the heat from the device and transfers it to the coolant, which temperature is ideally controlled by a chiller.
With over 20 years of experience in designing and producing the liquid cold plate, our products minimize the variation of surface temperature and achieve “Uniform Cooling”, and with a reliable brazing method to guarantee the airtightness with no water leak.

Uniform Cooling

Maximize the steady performance of your devices.

The surface temperature of the liquid cold plate tends to vary near the inflow and outflow points, due to the coolant absorbing the heat.
Uneven cooling can influence the performance of the device. Therefore, it is vital to design an optimized flow path to reduce surface temperature fluctuations.
We have a great deal of experience and skill in designing the optimal flow path to provide uniform cooling to the device.

Design

Design

If you are considering a liquid-cooling solution for your devices, we recommend choosing from our Standard Series and Semi-customized Series for a shorter lead time.
For customization, we need information such as the size and heat load of your device for the first step.
We will design and suggest the liquid cold plate strictly based on your requirements.

Our commitments

Surface flatness Accuracy

Surface Accuracy

In order to remove the heat from device, it is important to be fully contacted between the surface of the liquid cold plate and the device.
We guarantee that the surface flatness of our liquid cold pate is 0.02mm or less to be able to make perfect contact with device.

Brazing

The liquid cold plate is perfectly joined by our advanced brazing technology.
We guaranteed airtightness with no water leak.

The plate is perfectly joined by our advanced brazing technology.
We guaranteed water tightness with no leak.

Imperfect brazing caused water leak and corrosion.

Brazing

We’ve never had water leak problem since we‘ve started sales for 20 years

Surface Protection

Surface Protection

Plating treatment improves corrosion resistance of liquid cold plate.
We have our own plating equipment in our factory for continuous process with plating to avoid the transport damage.

Fitting connection

Pipe 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.
