What’s Inside a Wieland Microcool cold plate?

We cut open a Weiland Microcool cold plate so you could see the Micro Deformation Technology (MDT) pin fin inside. Our friction stir welded  construction and balanced parallel cooling flow path is also visible.

Wieland Microcool aluminum friction stir welded cold plates have been optimized specifically for the high heat flux of power electronics and silicon carbide. The MDT (micro deformation technology) inside allows for very low thermal resistance, low pressure drop and balanced parallel flow. Contact us today to talk about one of our standard or custom designs.

Why use Micro Deformation Technology for Liquid Cooling?

MicroCool Micro Deformation Technology (MDT) is a low-cost, non-subtractive manufacturing method for creating fin and pin surfaces for use in heat transfer applications. This patented process mechanically and plastically deforms the work piece to form finite and repeatable micro-channels.

How does this benefit you?

Liquid cooling of cold plates and base plates appears to be the near-term solution for the current cooling demand of the power electronics market. Although well-known manufacturing methods can produce adequate cold plates and base plates for liquid cooling, new manufacturing processes and associated new geometries could significantly improve the hydrodynamic and thermal performances of current solutions. A numerical and experimental investigation has been carried out in order to evaluate the impact on the thermal performances of new pin and fin geometries applied to liquid cooling of power electronics. It is concluded that new geometries can provide a significant improvement on the thermal performances.

Still using old cold plate technology? Friction Stir Welding is better

Why Friction Stir Welding is Better

Friction Stir Welding (FSW) is a solid-state joining process, meaning frictional heat is generated between the wear-resistant welding tool and the material of the workpieces. Joining the workpieces together while staying below the melting point. This creates a leak-proof seal that is stronger and more reliable than any other cold plate joining method.

Microcool uses the best technology

MicroCool has become the expert in FSW high conductivity 1100 series aluminum MDT pin plates into all types of machined, extruded and cast aluminum alloys.
