Description

technical field [0001] The invention relates to the field of heat storage and heat exchange, in particular to a phase change heat storage device and a heat exchange device. Background technique [0002] Nowadays, while relying on fossil fuels for energy supply, the use of energy is gradually developing towards diversified and clean energy sources. With the development and maturity of phase change energy storage technology, people are increasingly aware of the energy saving and Environmental performance. Compared with sensible heat storage, latent heat storage has high heat storage density and constant temperature heat release characteristics, which is conducive to matching with heat sources and loads. Unreasonable, uneven heat transfer of internal heat exchange elements, insufficient utilization of phase change energy storage materials, resulting in low heat transfer efficiency of existing phase change heat storage devices, and local temperature of phase change materials is...
