Title: George Francis Boesen: Downhole Cooling and Pressure-Sensing Innovations.

Introduction

George Francis Boesen is an inventor associated with Park Ridge, Illinois. His patent work includes technologies for cooling electronic components in deep wells and measuring pressure through changes in capacitance. His record lists 2 patents.

Latest Patents

Boesen’s “Downhole thermoelectric refrigerator” describes a system for protecting electronic components from the high temperatures found deep underground. The components are mounted on a thermoelectric cooler’s cold plate inside a vacuum-insulated dewar. A vapor-phase heat-transfer pipe and heat exchanger carry heat from the cooler’s hot plate to the surrounding well fluid, which serves as a heat sink.

His “Variable area capacitive pressure transducer with temperature” patent describes a sensor with two electrodes, one of which has a thin-film dielectric layer. As pressure deforms an electrode, the effective contact area between the electrodes changes, producing a corresponding change in capacitance. The disclosed circuit converts that change into a direct-current voltage, while temperature compensation helps account for thermal effects.

Career Highlights

The two inventions reflect Boesen’s work on instrumentation and engineering challenges in demanding environments. One addresses thermal management for downhole electronics, while the other focuses on pressure measurement and temperature compensation.
