Abstract

The present invention relates to the use of polymer-inorganic nanoparticle compositions as heat transfer fluids in batteries or other electrical equipment systems. The electrical devices may particularly be batteries, electric motors, electric vehicle transmissions, power transformers, capacitors, fluid-filled drive lines, fluid-filled power cables, computers, and power electronics such as power converters.

Description

technical field [0001] The present invention relates to the use of polymer-inorganic nanoparticle compositions as heat transfer fluids in batteries or other electrical device systems. The electrical equipment may in particular be batteries, electric motors, electric vehicle transmissions, power transformers, capacitors, fluid-filled drive lines, fluid-filled power cables, computers and power electronics such as power converters. Background technique [0002] In recent years, energy shortages and environmental concerns have had a huge impact on technological progress. Increased environmental awareness has led to a growing interest in so-called green technologies, especially in the automotive industry. The demand for emission-free vehicles fueled by renewable energy sources, such as pure electric vehicles (EVs), hybrid electric vehicles (HEVs), and fuel cell electric vehicles, has gradually become more pronounced and is expected to increase dramatically over the next 20 years...
