Description

Technical Field

[0001] This utility model relates to the field of storage device technology, specifically a polymer phase change material energy storage box. Background Technology

[0002] With the growth of global energy demand and the increasing emphasis on energy efficiency, efficient energy storage has become a key research direction. Among numerous energy storage technologies, phase change materials (PCMs) are widely studied and applied due to their ability to absorb or release large amounts of latent heat during phase transitions. In particular, polymeric PCMs, with their advantages of high energy density, low supercooling, good chemical stability, and adjustable operating temperature range, have shown great potential in areas such as building energy conservation, electronic device heat dissipation, and solar energy storage.

[0003] However, existing energy storage devices based on polymer phase change materials often have some shortcomings. First, traditional designs typically lack effective thermal conductivity enhancement structures, resulting in low heat transfer efficiency and limiting the full potential of the phase change material's energy storage performance. Second, these devices are mostly designed as monolithic structures; if any part fails, the entire unit needs to be replaced, increasing maintenance costs. Furthermore, the lack of modular design in existing devices makes them difficult to adapt to changing needs in different scenarios, reducing their engineering practicality and flexibility. Therefore, this invention proposes a polymer phase change material energy storage heat box. Utility Model Content
