Introducing our new cold plate series, CP 4000

The 4000 Series aluminum friction stir welded cold plates, use a new optimized extruded tub. The MDT (micro deformation technology) inside allows for the very low thermal resistance, low pressure drop and balanced parallel flow.

  • The flat bottom makes mounting easy as well as adds the option for double sided cooling (with or with out MDT pin fin on the backside).
  • The included hose barbs significantly reduce pressure drop associated with screw in fittings and are available in multiple sizes.

Same 10+ sizes available as our best in class 3000 series cold plates. Optimized to work with the most common module foot prints.

New versions optimized specifically for Wolfspeed 62mm, CAS325 & XM3 packages.

Double-sided versions are available.

 

Quick turn custom versions available.

Try our free online cold plate simulator

Wieland Microcool Tool is an online simulation tool for cold plates and cooling elements developed for a diverse range of electronic cooling applications including CPU configurations, racks, servers, GPU graphics chips, high-output LEDs, power modules, IGBTs, and power semiconductors.

This online software can help you quickly determine which type of MDT fin or pin geometry will best suit your performance needs. With just a few inputs, the correlation-based software:

  • Provides thermal resistance, cold plate and fluid temperatures, as well as pressure drop performance
    Evaluates straight fins, in-line pin fins, and staggered pin fin geometries
  • Handles single-phase coolants (best methods including entrance effects)
  • Determines once-through and split flow (for pressure drop designs)
  • Generates complete graphical simulations (including 3D PDF output with graphs and incremental calculation output of the thermal views) and set of input/output results

Contact us and we can help you run a simulation or you can test one of our off the shelf standard cold plates with fast shipping
from the US.

How it’s made – Wieland Microcool friction stir welded cold plate with MDT pin fin inside

Check out the video 

We start with an aluminum extrusion or plate, from there we machine the pockets for the MDT pin fin plates, and fluid manifolds.

Then we friction stir weld the fin plates into the tub or manifold. After welding we fly cut the top to remove the FSW flash and create the flat and smooth cooling surface. As a last step we add all holes, any finish machining and then leak test the finished cold plate.

Contact us to test one of our off the shelf standard cold plates or we can help you create a custom cold plate in days.

 

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.
