Introduction

Andrew Stillwell is an inventor associated with the University of Illinois in Champaign, Illinois. His patent work focuses on cooling electronics through water-based immersion systems and nano-structured coatings. He is credited with 2 patents.

Latest Patents

Stillwell’s latest patent work, titled “Immersion Cooling with Water-Based Fluid Using Nano-Structured Coating,” describes a system for cooling powered electronic components immersed in a water-based fluid. A condenser collects water vapor produced by heat from the components and allows it to condense and passively return to the fluid.

The system uses a nano-engineered coating on high-thermal components. The coating includes an electrical insulation layer between two and 25 microns thick, topped with a porous metallic nano-structure. This layered design supports heat transfer while electrically insulating the components.

A related method describes applying an electrical insulation coating, between one and 25 microns thick, to electronics on a printed circuit board using chemical vapor deposition. A porous metallic nano-layer is then deposited over the insulation. After these steps, the board is immersed in a water-based fluid to cool the electronics while they are powered on.
