Abstract
The invention discloses a kind of phase-change material for latent heat storage, including following component：Na2SO4·10H2O, borax, SrCl2·H2O.The present invention adds nucleator and thickener in inorganic hydrated salt class phase transformation material, solves the problems, such as to be nucleated poor performance during crystalline hydrate salt crystallization in the prior art.
Description
Technical field
The present invention relates to hot technical field of energy storage, more particularly to a kind of phase-change material for latent heat storage.
Background technology
Phase-change material (PCM-Phase Change Material) refers to vary with temperature and change state of matter and simultaneously can
The material of latent heat is provided.The process of transformation physical property is known as phase transition process, and at this moment phase-change material will absorb or release is substantial amounts of
Latent heat.Simultaneously because during phase transformation, temperature it is nearly constant, therefore can be used for adjusting the temperature of surrounding environment,
And can be with Reusability.Since the application of phase-change material is quite varied, it has become the new material of people's pay attention to day by day.
Many inorganic crystal hydrated salts usually have the fusing point of the larger heat of transformation and fixation, and the crystallization water of abjection dissolves salt
And absorb heat, inverse process occurs for when cooling, absorbs crystallization water heat release, so being used frequently as latent heat type heat accumulating.Crystalline hydrate
Salt is typically middle low temperature heat storage phase-changing material, its main feature is that use scope is wide, price is relatively inexpensive, and thermal conductivity factor is big, and density is big, single
Position volume storage density is big, is generally in neutrality.The drawback is that degree of supercooling is big, easily separates out, the reason is that most of crystalline hydrate salt
Poor performance is nucleated during crystallization.Present invention mainly solves this problem.
The content of the invention
The present invention provides a kind of phase-change material for latent heat storage aiming at above-mentioned defect.The present invention
Nucleator and thickener are added in inorganic hydrated salt class phase transformation material, when solving crystalline hydrate salt crystallization in the prior art into
The problem of core poor performance.
A kind of phase-change material technical solution for latent heat storage of the present invention is, including following component：Na2SO4·
10H2O, borax, SrCl2·H2O。
A kind of phase-change material for latent heat storage, further includes atlapulgite.
A kind of phase-change material for latent heat storage, is made of following component by weight：Na2SO4·
10H2O 65-85, borax 1-3, SrCl2·H2O 1-3, atlapulgite 2-8.
A kind of phase-change material for latent heat storage, is made of following component by weight：Na2SO4·
10H2O 75, borax 2, SrCl2·H2O 1, atlapulgite 6.
Beneficial effects of the present invention are：The present invention adds nucleator and thickener in inorganic hydrated salt class phase transformation material,
Solve the problems, such as to be nucleated poor performance during crystalline hydrate salt crystallization in the prior art.Degree of supercooling is less than 2 DEG C, and crystalline rate is small, brilliant
Body is laxer, and more transparent.
