Abstract

The invention discloses a phase change energy storage device and system. The phase change energy storage device comprises a shell, an inner container, a plurality of phase-change energy storage elements, a circulating medium inlet, a circulating medium outlet and circulation medium, wherein an inner container used for containing the phase-change energy storage elements is arranged in the shell, acirculating medium inlet and a circulating medium outlet are formed in the side surface of the inner container, the circulating medium is filled in the inner container, and the phase-change energy storage elements comprises a phase-change material and a plastic package body used for containing the phase-change material. The phase-change energy storage device solves the problem of leakage of the phase-change material from the phase-change energy storage elements, so that the energy is rapidly stored and released, the heat exchange power is large, is safe and reliable, and can continuously and stably output energy.

Description

technical field [0001] The invention relates to the technical field of phase change material energy storage, in particular to a phase change energy storage device and system. Background technique [0002] Phase change energy storage has gradually become an important means in the field of energy storage. Phase change materials mainly include inorganic phase change materials, organic phase change materials and composite phase change materials, each of which has its corresponding phase change melting point. In use, take solid-liquid phase change as an example, when the temperature at the heat source reaches the melting point of the phase change material, the phase change material absorbs heat from the heat source in the form of latent heat, and when the temperature is lower than the melting point of the phase change material, The latent heat of phase change is then released to achieve the purpose of energy storage. [0003] In the prior art, there are generally two types of ph...
