2 MicroCool a Division of Wolverine Tube Inc. Wolverine has 100+ years history with decades long customer partnerships. In 1935, Wolverine invented the first high performance heat transfer tubes and revolutionized the HVAC commercial chiller industry. Wolverine is the premier heat transfer design partner for OEM s like Carrier, Trane, Parker, York. Global core markets served: HVAC, Refrigeration & Appliance, Water Heater/Boiler, Process & Chemical, Electronics Cooling.

3 MicroCool Division The MicroCool division has leveraged Wolverine s MDT tube surface enhancement technologies and transferred the technology to flat plates. This technology is used to create baseplates for power electronics, liquid cooled coldplates, two phase evaporators, micro-channel surfaces and much more. In 2013 Microcool launched a catalog line of standard liquid cooled coldplates specifically for the cooling of power electronics, as well as a free on-line coldplate simulator. Today MicroCool continues to innovate and now has the best performing mass produced coldplates on the market. Through smart design and complementary core technologies MicroCool coldplates are also the most cost effective. Wolverine MDT Enhanced Tube MicroCool MDT Enhanced Flat Plate

4 MicroCool Core Technologies: Micro Deformation Technology (MDT) Micro Deformation works like a plow in a field: Our patented tooling moves through ductile materials (typically aluminum or copper) to create fins and pin fins without wasting material or scrap. Fin pattern range: Density: fins per inch. Fin thickness: fin thickness = gap Fin Height: 0.5-6mm Pin pattern range: Density: fins per inch Pin thickness: mm dia and min gap Pin Height: 1-8mm Pin pattern is in line and not staggered In line pin fin 20fpi (XP) In line pin fin 12fpi

5 MicroCool Core Technologies: Friction Stir Welding (FSW) 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 work pieces. Joining the work pieces 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 has become the expert in friction stir welding high conductivity 1100 series aluminum MDT pin plates into all types of machined, extruded and cast aluminum alloys.
