Abstract
The invention discloses a novel metal base material shaping heat accumulating material and a preparation method thereof. The heat accumulating material is prepared by compounding paraffin and porous foamy copper, wherein the mass fraction of paraffin is 83.2%, the mass fraction of porous foamy copper is 16.8%, the melting point of the selected paraffin in the material is 40-60 DEG C, and the voidage of the selected porous foamy copper is 98% or above. The material has the advantages that the heat absorption and discharge speed is quick, and the appearance after phase change is unchanged.
Description
One, technical field
The present invention relates to phase-change heat-storage material field, refer in particular to and a kind ofly utilize paraffin, heat accumulating prepared by porous foam copper compound.
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 novel metal base material sizing heat accumulating, 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, when there is solid-liquid phase change, shape invariance can be kept.
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 novel metal base material sizing heat accumulating, it is characterized in that: this heat accumulating is made up of paraffin, porous foam copper compound, wherein the massfraction of paraffin accounts for 83.2%, the massfraction of porous foam copper accounts for 16.8%, the paraffin melting point selected in above-mentioned materials is between 40 DEG C-60 DEG C, and the porous foam copper voidage selected is more than 98%.
The preparation method of above-mentioned novel metal base material sizing heat accumulating, 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, paraffin fused solution is injected mould, and just submergence porous foam copper;
(3) by paraffin, the cooling of porous foam copper composition, remove mould, obtain metal base sizing heat accumulating.
The present invention has two 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 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 according to the size of φ 46*1500 the mould melting paraffin, and ready-made porous foam copper is inserted in mould.Heating paraffin is melted, and injects mould, and just submergence porous foam copper, obtain heat accumulating of shaping 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 16.8%, and Quality of Paraffin Waxes mark accounts for 83.2%.This material phase transformation latent heat is 150kJ/kg, and thermal conductivity is 8.9W/ (mK).
