The heat-storage material is prepared from compounding sodium sulfate decahydrate, expanded graphite and porous foamed copper, wherein the mass percentage of the sodium sulfate decahydrate accounts for 80.1%; the mass percentage of the expanded graphite accounts for 8.9%; the mass percentage of the porous foamed copper accounts for 11%; and the voidage of the porous foamed copper selected in the above-mentioned materials is more than 98%. The material has the advantages of rapid heat-absorption and heat-release efficiencies, large heat storage capacity, and invariant shape after phase change.
Description
One, technical field
The present invention relates to phase-change heat-storage material field, refer in particular to a kind of heat accumulating utilizing sal glauberi, expanded graphite, porous foam copper compound to prepare.
Two, background technology
Energy-conservation is an important topic of field of energy utilization with environmental protection, utilizes the latent heat of phase change storage power of phase-change heat-storage material to be a kind of novel power-saving technology.Phase change material, in phase transition process, absorbs the heat of surrounding environment, and when envrionment temperature reduces around, Environment release heat towards periphery, thus reach control ambient temperature and energy-conservation object.It all has wide practical use in fields such as Solar use, energy recovery, air conditioner refrigerating, building energy conservation, aerospace.
Sun power, as a kind of energy of inexpensive clean, is widely used in the middle of productive life at present, but quantitatively with on the time can not well mate and coordinate due to the supply and demand of sun power, causes mass energy to waste.As superfluous in sun power on daytime, cause sun power to waste, and night and overcast and rainy sun power not enough.The shortcoming of current heat accumulating ubiquity heat conductivility difference, the phase-change thermal storage parts therefore made, due to poor thermal conductivity, cannot give full play to the heat storage function of heat accumulating.Secondly, during heat accumulating generation solid-liquid phase change, fluid leakage problems can be caused.
In order to solve the problem, by phase-change heat-storage material and the strong base material compound of certain capacity of heat transmission, and shaping material can be added, making a kind of novel heat accumulating, improve thermal conductivity and the sizing characteristics of heat accumulating.
Three, summary of the invention
The object of this invention is to provide a kind of inorganic compounding sizing phase-change heat-storage material, the phase-change thermal storage temperature of this heat accumulating is in the operating temperature range of solar water heater, and latent heat of phase change is higher, and heat conductivility is better.
Another object of the present invention is to provide the preparation method of above-mentioned heat accumulating.
The object of the invention is to be achieved through the following technical solutions:
A kind of inorganic compounding sizing phase-change heat-storage material, it is characterized in that: this heat accumulating is made up of sal glauberi, expanded graphite, porous foam copper compound, wherein the massfraction of sal glauberi accounts for 80.1%, expanded graphite massfraction accounts for 8.9%, the massfraction of porous foam copper accounts for 11%, and the porous foam copper voidage selected in above-mentioned materials is more than 98%.
The preparation method of above-mentioned inorganic sizing phase-change heat-storage material, adopts following steps:
(1) by the shape required for porous foam Copper fabrication one-tenth and size;
(2) make mould according to required shape, the porous foam copper processed is placed in mould;
(3) Graphite Powder 99 of drying is placed in encloses container and is heated to 800 DEG C, form expanded graphite;
(4) melted by sal glauberi, add expanded graphite according to 10% mass ratio, mixture, after 1 hour, is injected mould by whip attachment, makes mixture liquid just submergence porous foam copper;
(5) by sal glauberi, expanded graphite, the cooling of porous foam copper composition, remove mould, obtain high heat conduction phase-change heat-storage material.
The present invention has three advantages:
(1) the heat accumulating heat conductivility prepared of the present invention is higher, and exotherm rate is faster in heat absorption;
(2) heat accumulating that prepared by the present invention maintains the physics-chem characteristic of each composition of heat accumulating, has stable, that enthalpy of phase change is high feature.
(3) heat accumulating that prepared by the present invention can not change its profile when phase transformation, can effectively prevent from revealing.
Four, embodiment
Below with example, embodiments of the present invention are described further:
Porous foam Copper fabrication is become the right cylinder of φ 46*1500.Make mould according to the size of φ 46*1500, and ready-made porous foam copper is inserted in mould.The Graphite Powder 99 of drying is placed in encloses container and is heated to 800 DEG C, form expanded graphite.By sal glauberi heat fused, add expanded graphite according to 10% mass ratio, mixture, after 1 hour, is injected mould by whip attachment, makes mixture liquid amount just submergence porous foam copper.Heat accumulating of shaping is obtained after mould is removed in cooling.Porous foam copper selects the material of porosity 98%, and therefore in mixture, porous foam Copper mass fraction accounts for 11%, and sal glauberi massfraction accounts for 80.1%, and expanded graphite massfraction accounts for 8.9%.This material phase transformation latent heat is 192kJ/kg.
