These improvements stem from innovative changes to the evaporator structure, particularly the wick. The team made it thinner, longer, and wider while maintaining its high-quality porous properties. They also optimized vapor escape channels, increasing their number and efficiency. "The uniqueness of this LHP is in the shape, quality, and size of the wick," explains Professor Nagano. "Usually, when making larger wicks, the quality decreases, but we've maintained similar quality to smaller wicks." Implications for Industry and Sustainability This breakthrough could be big for several sectors:
