The automotive industry continues to be a hotbed of patent innovation. Government regulations, consumer demand, technological advancements, and cost reduction are driving innovation in eco-friendly cooling circuits for the automotive industry. Variable displacement pumps, two-phase cooling, organic Rankine cycle systems, and thermoelectric cooling are some examples of these technologies. As the automotive industry moves towards sustainable practices, more eco-friendly cooling circuits are expected to be developed. Eco-friendly cooling circuits in the automotive industry include variable displacement pumps, two-phase cooling, organic Rankine cycle (ORC) systems, and thermoelectric cooling. Variable displacement pumps improve fuel efficiency and reduce emissions by adjusting coolant flow. Two-phase cooling uses vaporized refrigerant, while ORC systems generate electricity from engine waste heat. Thermoelectric cooling uses the Peltier effect but is expensive and requires a large amount of electricity. In the last three years alone, there have been over 1.7 million patents filed and granted in the automotive industry, according to GlobalData’s report on Environmental sustainability in automotive: eco-friendly cooling circuitsBuy the report here.
