Title: Mark J. Defranza: Corrosion-Resistant Heat-Sink Innovation.

Introduction

Mark J. Defranza is an inventor associated with Camas, Washington, and Nlight, Incorporated. His patent work addresses heat management in systems that use liquid cooling, with a focus on protecting heat-sink channels from corrosion while preserving thermal performance.

Latest Patents

Defranza is credited with 1 patent: “Corrosion Resistant Heatsink Method, System, and Apparatus.” The invention describes a heat-source package with a metal base containing channels for liquid coolant. An anti-corrosive coating is applied to part of the channels’ inner surfaces, and its thermal conductivity is selected so that it changes the coated portion’s thermal resistance by less than 25% compared with an uncoated portion. The channels can carry coolant from an inlet to an outlet, helping dissipate heat from a thermally coupled heat source.

Career Highlights

The patent reflects an engineering approach that balances corrosion protection with efficient heat transfer. By specifying a limit on the coating’s effect on thermal resistance, the design aims to protect coolant channels without substantially compromising their cooling function. Defranza is associated with Nlight, Incorporated.

Collaborations

Eric Martin is identified as Defranza’s coworker. The available information does not specify whether Martin collaborated on the patent.

Conclusion

Mark J. Defranza’s patent presents a corrosion-resistant liquid-cooling design that seeks to protect heat-sink channels while maintaining effective thermal performance.
