Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
Number in the figure:
1-front surface; 2-is surface instead; 3-division surface; 4-the first energy-accumulating medium; 5-the second energy-accumulating medium.The specific embodiment
This utility model provides a kind of solar heat-preservation type hand warmer that utilizes ferroferric oxide magnetic fluid, below in conjunction with the drawings and specific embodiments, this utility model is described further.
As shown in Figure 1, hand warmer front surface 1 described in the utility model and division surface 3 are layer of transparent plastic material, anti-surface 2 has the nontransparent plastic material of arbitrary graphic pattern and color for one deck, the alignment of three edge seals by high-temperature laminating, inside has formed two bag-shaped spaces, is called upper strata and recuperation layer.The first energy-accumulating medium 4 is filled on upper strata, is water base ferroferric oxide magnetic fluid, and wherein ferroso-ferric oxide is the nanoparticle of particle diameter 20nm, and fluid matrix is deionized water, and the shared volume ratio of ferroferric oxide particle in the first energy-accumulating medium 4 is 5%.In recuperation layer, be full of the second energy-accumulating medium 5, for having filled the phase change heat storage material of nanoparticle, described nanoparticle is the ferroso-ferric oxide of particle diameter 20nm, phase change heat storage material is No. 66 paraffin, its phase transition temperature is 66 ℃, under room temperature, be solid, in the second energy-accumulating medium 5, the shared volume ratio of ferroferric oxide particle is 4%.
Hand warmer is faced up, place in the sun, when hand warmer temperature reaches 66 ℃, the material in recuperation layer continues absorb a large amount of heat and be slowly transformed into liquid by solid, reaches the object of " filling heat ".When material all becomes liquid state in recuperation layer, be the most applicable moment of bringing into use of this hand warmer.Along with use, the outside heat release of hand warmer, in recuperation layer, phase change heat storage material solidifies simultaneously, to upper strata heat release, plays the effect of thermal source.After heat-storing material all solidifies, along with continuing heat release, hand warmer temperature reduces gradually.Phase transition process temperature remains unchanged, and this has just guaranteed the condition of high temperature (66 ℃) that hand warmer can maintain a more long, and has reached the object extending working time simultaneously.
The ferroferric oxide particle of filling in energy-accumulating medium is nanoscale, and its particle diameter is less more to the raising of material thermal conductivity, and the effect that nano-fluid body absorbs is more obvious, fills thermal velocity faster.In recuperation layer, required paraffin is selected paraffin No. 66, along with carrying out hand warmer temperature, recuperation layer phase transition process remains on 66 ℃ of left and right always, in charging process in recuperation layer paraffin all become liquid after hand warmer temperature will rise and continue to rise by 66 ℃, in exothermic process when recuperation layer in paraffin all become solid-state after hand warmer temperature will be by 66 ℃ continuation declines.In recuperation layer, required paraffin can be selected the paraffin of No. 52, No. 54, No. 56, No. 58, No. 60, No. 62, No. 64, No. 66, No. 68, No. 70 different trades mark, now the variations in temperature feature of hand warmer in filling heat, exothermic process in like manner, the time that remains on corresponding phase transition temperature is the longest, and the concrete persistent period is relevant with the consumption of material.
This utility model is not restricted to the described embodiments; that in above-described embodiment and description, explains just illustrates principle of the present utility model; under the premise of not departing from the present invention; this utility model also has various changes and modifications, and these changes and improvements all fall within the scope of this utility model of protection.The claimed scope of this utility model is defined by appended letter of authorization and equivalent thereof.
