Abstract

The invention discloses a phase change energy storage material with good stability, which comprises zinc dichloride, sodium hydroxide, potassium phosphite, sodium chromate, potassium fluoride, lithium nitrate, zinc nitrate, dibromo Calcium chloride, water, the ratio of each component of the phase change energy storage material with good stability is: in parts by weight, 15-20 parts of zinc dichloride, 13-16 parts of sodium hydroxide, 8 parts of potassium phosphite ‑14 parts, 2‑6 parts of sodium chromate, 9‑16 parts of potassium fluoride, 2‑6 parts of lithium nitrate, 1‑7 parts of zinc nitrate, 11‑15 parts of calcium dibromide, 40‑45 parts of water. Through the above method, the phase change energy storage material with good stability performance of the present invention can still have very good stability after long-term storage, without affecting the performance of use, and still has good stability under high temperature and low temperature conditions , less affected by environmental changes, easy to store, and use for a long time.

Description

technical field [0001] The invention relates to a phase change energy storage material, in particular to a phase change energy storage material with good stability. Background technique [0002] The emergence of phase change materials reflects the extension of the constant temperature time, and can store or release sensible heat during thermal cycles with sensible heat and insulating materials. The principle is: the phase change material stores energy during the heat transfer process, just like thermal resistance, it can prolong the energy transfer time and reduce the temperature gradient. Since phase change materials have the ability to store heat in the form of latent heat or release it to the environment during the phase change process, the introduction of phase change materials into real life through proper design can make the influence of external temperature and heat flow fluctuations be eliminated. weaken. The performance of the existing phase change energy storage ...
