Research progress on heat transfer performance of phase change microcapsule suspension for storage

Phase change microcapsule suspension is a solid-liquid two-phase fluid formed by encapsulating phase change materials in microcapsules and dispersing them in single-phase fluids. The suspension has fluidity and can store and release a large amount of heat within a narrow temperature range, making it significantly advantageous in thermal energy applications. This article introduces the configuration method of phase change microcapsule suspension, summarizes its enhanced heat transfer mechanism and key factors affecting heat storage and transfer performance, and analyzes the key issues in the application of phase change microcapsule suspension: stability, durability, and heat storage and transfer performance. Finally, the application of microcapsule suspension in construction, solar photovoltaic/thermal utilization, and heat dissipation of power equipment was introduced.
