1. Overview: 2. Background: The paper begins by highlighting the increasing concentration of greenhouse gases (GHGs) since the 1900s, primarily due to the combustion of fossil fuels in internal combustion engines (ICEs). Transportation is a significant contributor to these emissions. Electric Vehicles (EVs) and Hybrid Electric Vehicles (HEVs) are presented as promising solutions to reduce
1. Overview: 2. Research Background: High-power LEDs are increasingly popular in various applications, offering advantages like long lifespan, high reliability, low energy consumption, fast response time, and color variability. However, their efficiency (15-25% power-to-light conversion) is limited, with over 80% of power dissipated as heat, leading to high junction temperatures. Maintaining junction temperatures below 120°C
1. Overview: 2. Research Background: Plate-fin heat exchangers are widely used for heat dissipation in automotive engines due to their compact and lightweight structure, excellent heat transfer performance, and low production cost. Serrated staggered fins are commonly employed to enhance the heat exchange surface. Previous studies have applied novel algorithms, such as genetic algorithms, simulated
1. Overview: 2. Research Background: Fins and heat sinks are widely used thermal elements crucial for efficient heat removal. Efficient heat removal necessitates a low cost, and factors such as fin profile, material properties, surface properties, raw material cost, and manufacturing cost are decisive in selecting competitive materials.
