Description
Technical field
The present invention relates to a kind of energy storage device, in particular to a kind of sun power and hot formula water base phase change heat accumulator.
Background technology
Sun power is as the unlimited renewable energy source of one, the favor being more and more subject to people in recent years, but due to factors such as geographical, weather and seasons, cause the interruption that sun power uses, in order to make sun power to be used continuously, it is necessary to effective solution accumulation of energy problem.
The solar heat-preservation device used at present, its efficiency is general not high, and heat exchange is slower. Major part sun power is not absorbed by thermophore and is just reflected back toward in air, and from Energy harvesting angle, its efficiency is very low, and inconvenience uses.
Summary of the invention
The present invention be directed to the problem that solar heat-preservation energy utilization efficiency is low, it is proposed that a kind of sun power and hot formula water base phase change heat accumulator, can not only effectively improve solar absorptance, and decrease heat lost by radiation. For the application of solar energy collector opens approach widely.
The technical scheme of the present invention is: a kind of sun power and hot formula water base phase change heat accumulator, comprise dual-layer vacuum glass involucrum, the mixture of energy storage particle and water, heat exchange copper comb, anti-expansion spring plug, dual-layer vacuum glass involucrum is cylindrical, heat exchange copper comb one exports an entrance outside dual-layer vacuum glass involucrum, heat exchange copper comb gangway is symmetrically placed in dual-layer vacuum glass involucrum exit end up and down, it is inner that all the other heat exchange copper combs are looped around dual-layer vacuum glass involucrum, heat exchange copper comb in dual-layer vacuum glass involucrum and be filled with the mixture of energy storage particle and water between dual-layer vacuum glass involucrum inwall, dual-layer vacuum glass involucrum export center is closed with anti-expansion spring plug.
Heat exchange copper comb in described dual-layer vacuum glass involucrum and after filling full energy storage particle between dual-layer vacuum glass involucrum inwall, then add water in dual-layer vacuum glass involucrum, make to be full of between particle in whole energy storage water.
Described energy storage particle is containing carbon fiber-reinforced accumulation of energy particle.
The useful effect of the present invention is: sun power of the present invention and hot formula water base phase change heat accumulator, owing to carbon fiber density is little, price is cheap, itself have again not defeated in the capacity of heat transmission of common metal material, enhance the heat exchange property of accumulation of energy particle, do not increase the quality of energy storage simultaneously yet, and carbon fiber add the blackness that improve phase change material, enhance phase change material to the direct receptivity of sun power, avoid from heat collector Surface absorption sun power again to the heat exchange approach that the thermal resistance of phase change material heat exchange is higher; Sun power is directly radiated on inner accumulation of energy particle through dual-layer vacuum glass involucrum, is absorbed in water based phase-change material inside, it does not have any conduction process, decrease heat exchange loss, decrease the reflection loss of sun power, it is to increase to the utilization ratio of sunlight. Owing to the heat exchange of the existence of water, phase change material and plumbers shed is turned into the convective heat exchange of energy storage particle and plumbers shed from heat conduction, the phase change material solidified inside that simultaneously avoids enhancing heat exchange produces the shortcoming that space hinders heat exchange further. The use of dual-layer vacuum glass involucrum, has effectively carried out heat radiation protection to thermophore, and what extend heat energy stores the time. Heat-exchange working medium flows through copper comb, can carry out rapidly heat exchange, and conveying is to user.
Accompanying drawing explanation
Fig. 1 is sun power of the present invention and hot formula water base phase change heat accumulator structural representation.
Embodiment
Sun power and hot formula water base phase change heat accumulator structural representation as shown in Figure 1, sun power and hot formula water base phase change heat accumulator comprise dual-layer vacuum glass involucrum 1, the mixture 2 of energy storage particle and water and heat exchange copper comb 3, anti-expansion spring plug 4, dual-layer vacuum glass involucrum 1 is cylindrical, heat exchange copper comb 3 one outlet one entrance is outside dual-layer vacuum glass involucrum 1, heat exchange copper comb 3 gangway is symmetrically placed in dual-layer vacuum glass involucrum 1 exit end up and down, it is inner that all the other heat exchange copper combs 3 are looped around dual-layer vacuum glass involucrum 1, heat exchange copper comb 3 in dual-layer vacuum glass involucrum 1 and be filled with the mixture 2 of energy storage particle and water between dual-layer vacuum glass involucrum 1 inwall, dual-layer vacuum glass involucrum 1 export center is closed with anti-expansion spring plug 4.
The mixture 2 of energy storage particle and water is for absorbing and stores heat, and heat-exchange working medium enters from import, by copper comb heat exchange, then by outlet conveying to user. Energy storage is particles filled extremely convenient, after having filled accumulation of energy particle, add water in dual-layer vacuum glass involucrum 1 again, make in whole energy storage, between particle, to be full of water (can flow, exchange capability of heat is strong, have certain heat storage capacity), thus the heat exchange between reinforced transformation material and comb.
Being arranged so that in energy storage energy-accumulation material expanded by heating and can not cause breaking of glass involucrum 1 of anti-expansion spring plug 4. Heat-exchange working medium enters from import, after heat exchange copper comb 3 heat exchange, both can be used to user's heat supply, can be used as again the thermal source driving absorption type refrigerating, it is achieved cold and heat combined supply so that the purposes of sun power becomes more extensive.
What the phase change material in thermophore adopted is containing carbon fiber-reinforced accumulation of energy particle. Carbon fiber add the blackness that improve phase change material, enhance phase change material to the direct receptivity of sun power, avoid from heat collector Surface absorption sun power again to the heat exchange approach that the thermal resistance of phase change material heat exchange is higher; Can effectively reduce the heat exchange loss of hot matchmaker, store a large amount of heat energy, carry out quick heat exchange, it is to increase the whole efficiency of equipment.
