Your Total Heatsink and Thermal Management Solution

Thermal Solutions International, Inc. (TSI) is an industry leader in engineered thermal management heatsink solutions and is headquartered in Moorpark, California. At TSI, we specialize in quick turn prototype and production runs of heatsinks in all shapes and sizes.

Our customer’s time is greatly valued and we fully understand quick response. Give us a call or send us an email and let us show you what true customer service is made of. We want to be your one stop shop for all your heatsink requirements.

Board Level to High Power Heatsinks

We carry a wide array of products that range from smaller Board Level, BGA, and DC/DC Converter heatsinks up to larger, High Power, High Fin Density heatsinks in excess of 18” wide. TSI manufactures both natural and forced convection heatsinks from our unrivaled extruding capabilities. For the occasional heatsink that is beyond current extruding limitations, we offer Skived Fin, Bonded Fin, and Folded Fin designs.

We also have the ability to cross obsolete Thermaflo extrusions and Thermaflo custom part numbers to keep your existing design intact. Contact Us with any drawings you need quoted or to learn more about our capabilities.
