Title: The Innovations of Timothy Michael Grewe
Introduction
Timothy Michael Grewe is a notable inventor based in Endicott, NY (US). He holds a total of 14 patents, showcasing his significant contributions to the field of hybrid electric vehicles and advanced cooling technologies.
Latest Patents
One of his latest patents is for a supercharged hybrid electric vehicle. This innovative vehicle design includes an internal combustion engine that drives a generator to produce electrical energy for the vehicle's traction motor. The generator is equipped with a cooling air intake port, and an air mover or compressor is driven from the engine or an auxiliary motor to produce air under positive pressure. This air is then directed to the cooling air input port of the generator and the combustion air input port of the engine. The air mover not only cools the generator but also enhances engine performance, acting similarly to turbocharging or supercharging, depending on its type.
Another significant patent is the phase change assisted heat sink for electric vehicles. In this design, the traction motor is powered by a battery through a controllable electric power switcher. The power losses of the switches vary with the power being handled, leading to potential overheating during acceleration. Grewe's phase-change heat sink absorbs excess heat from the switches during high-demand situations and returns it to the cooler under more stable conditions, ensuring optimal performance.
