Latest Patents

Keju An's most recent patent is titled "Density controlled phase-changing material (PCM) spheres for increased heating power and optimal delivery temperature in hot-water tanks." This invention involves a medium for energy storage that includes a plurality of capsules. Each capsule contains a phase-changing material (PCM) designed to undergo a liquid-solid phase transition at a specific solidification temperature. The PCM experiences a relative volume change during this phase transition, which is crucial for its functionality. The design includes a shell filled with the PCM, which contains a first heat-conducting material and is configured to accommodate the relative volume change. This change generates a buoyancy force that acts on the capsule when submerged in water, optimizing its performance based on the water temperature.
