4000 Series Standard Cold Plates

High Performance, Scalable and Customizable Cold Plates


Wieland Microcool 4000 Series cold plates are the next evolution of our standard cold plate line. The 4000 series are designed to fit the most common power electronic footprints and can be easily customized for other needs.

The MDT™ pin fin inside, extruded and friction stir welded construction, and balanced parallel cooling offers lower thermal resistance, lower pressure drop, and competitive pricing.

If these “off the shelf” standard cold plates do not meet your requirements, please contact us to discuss custom cold plate options to meet the needs of your specific application.
