Researchers at the University of Tokyo have developed a new way to cool electronic chips using advanced water-based systems.The cooling method utilizes water's latent heat, which is seven times more powerful than sensible heat.A special 3D network of microchannels, capillary structures, and a manifold layer are designed to manage the boiling process inside the chip.The system's coefficient of performance (COP) reached up to 105, providing efficient cooling power for high-power electronics.
