Abstract
The invention discloses a metal substrate highly heat-conducting heat storage material and a preparation method therefor. The heat storage material is prepared by compounding 75% by mass of paraffin and 25% by mass of through-hole foamed aluminum. The melting point of selected paraffin in the materials is 40-60 DEG C, and the porosity of the selected through-hole foamed aluminum in the materials is over 90%. The material has the advantages of being fast in heat absorption and heat release speed and great in heat storage.
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 fine-crystal spume aluminium alloy 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.
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 the heat conductivility of heat accumulating.
Three, summary of the invention
The object of this invention is to provide a kind of metal base height heat conduction 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.
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 metal base height heat conduction heat accumulating, it is characterized in that: this heat accumulating is made up of paraffin, fine-crystal spume aluminium alloy compound, wherein the massfraction of paraffin accounts for 75%, the massfraction of fine-crystal spume aluminium alloy accounts for 25%, the paraffin melting point selected in above-mentioned materials is between 40 DEG C-60 DEG C, and the fine-crystal spume aluminium alloy voidage selected is more than 90%.
The preparation method of above-mentioned novel metal base material height heat conduction heat accumulating, adopts following steps:
(1) fine-crystal spume aluminium alloy is processed into required shape and size;
(2) make mould according to required shape, the fine-crystal spume aluminium alloy processed is placed in mould;
(3) paraffin fused solution is injected mould, make paraffin just submergence fine-crystal spume aluminium alloy;
(4) by paraffin, the cooling of fine-crystal spume aluminium alloy mixture, remove mould, obtain metal base height heat conduction 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 maintains the physics-chem characteristic of paraffin, has stable, that enthalpy of phase change is high feature.
Four, embodiment
Below with example, embodiments of the present invention are described further:
Fine-crystal spume aluminium alloy is processed into the right cylinder of φ 46*1500.Make according to the size of φ 46*1500 the mould melting paraffin, and ready-made fine-crystal spume aluminium alloy is inserted in mould.Heating paraffin melted, and inject mould, paraffin amount is submergence fine-crystal spume aluminium alloy just, obtains heat accumulating of shaping after mould is removed in cooling.Fine-crystal spume aluminium alloy selects the material of porosity 90%, and therefore in mixture, fine-crystal spume aluminium alloy massfraction accounts for 25%, and Quality of Paraffin Waxes mark accounts for 75%.This material phase transformation latent heat is 135kJ/kg, and thermal conductivity is 4.2W/ (mK).
