Fig. 1 is shown using the solar energy Stirling generator principle schematic diagram according to the disclosure.As shown in figure 1, the sun Energy stirling generator includes solar energy heating unit 100 and stirling generator 200.Solar energy heating unit 100 with collection The relative side of hot plate 110 is provided with through hole 130, and the hot chamber 210 of stirling generator 200 is arranged through the through hole 130 Into in the accommodating chamber of low-melting-point metal 120 of the solar energy heating unit, used between the outside of the hot chamber 210 and through hole High temperature thermal insulation material seals (not shown), and the hot chamber 210 is described low into being partially immersed in low-melting-point metal accommodating chamber In the low-melting-point metal of the accommodating chamber of melting point metals 120.
On daytime, when system works, sunshine is shining upon collecting plate by gathering thermal-arrest panel after lens reflecting When 110, the solar energy received by collecting plate 110 changes into heat energy, and heat energy is directly passed in heat collector cavity by collecting plate 110 Heat-transfer working medium 120, such as low melting point liquid metal 120.Close to low melting point liquid metal 120 and the hot chamber 210 weeks of collecting plate 110 The low melting point liquid metal 120 enclosed carries out heat convection so that the temperature of low melting point liquid metal 120 in whole heat collector cavity reaches Uniform temperature, so that the hot chamber 210 of stirling generator 200 is uniformly heated, so as to carry out stable electric generation.Stirling generator The electricity generating principle of 200 generators is common knowledge, herein without repeating.
Due to sunshine direction of illumination tracing-positioning system precision problem, thermal-arrest panel 110 may be present can not be complete Situation about irradiating entirely.Such as thermal-arrest panel 110 there are two parts of illumination and no light, it is impossible to reach that whole surface illumination is equal It is even.Have two parts of illumination and no light temperature difference greatly, the unglazed temperature shown up can only achieve higher than environment temperature several Ten degree, and have plane of illumination that several Baidu can be reached to thousands of degree.Added although being used above by fusing point liquid metal 120 come uniform The hot chamber 210 of hot stirling generator 200, but the underspeed of convective heat transfer with cause in heat collector cavity low melting point liquid gold Belong to 120 temperature and be rapidly reached uniform temperature, this is so that the Stirling around the relatively low liquid low-melting-point metal of temperature is sent out The hot chamber of motor 200 can not fully obtain heat and elevated predetermined temperature, therefore generating efficiency generates electricity with respect to other Stirlings The generating efficiency of machine 200 is relatively low, so solar energy can not be made full use of to be generated electricity.
Therefore, in order to further improve the utilization ratio of solar energy.Inventor enters to above-mentioned solar energy Stirling generator Transformation is gone.Shown in Fig. 2 is shown according to the another of the solar energy heating unit of disclosure solar energy Stirling generator Plant the schematic diagram of embodiment.As shown in Fig. 2 the solar energy heating unit 100 of solar energy Stirling generator also includes graphene Piece or graphene film 140.As shown in Fig. 2 graphene film 140 is arranged in the collecting plate 110 of the solar energy heating unit Side the end face of hot chamber 210 of stirling generator between and be fixed on the side wall of solar energy heating unit.Graphene film 140 Whole low-melting-point metal accommodating chamber is traversed, and is immersed in the low-melting-point metal 120 of the accommodating chamber.Therefore, solar irradiation is worked as Penetrate direction tracing-positioning system precision deficiency and cause thermal-arrest faceplate part partly not illuminated by focus irradiation and cause collection When there is huge temperature difference in this two parts on hot panel, on the one hand, pass through the liquid metal pair in low-melting-point metal accommodating chamber Stream carries out heat transfer, on the other hand, because graphene film 140 is connected with thermal-arrest panel 110, therefore, because graphene film 140 High transverse heat transfer performance, the heat that thermal-arrest panel 110 is in high-temperature part passes to rapidly graphene by heat transfer Piece 140, graphene film 140 run through whole surface pass to encirclement its liquid low-melting-point metal.It is main by both Intensified heat transfer method, the Temperature Distribution of liquid low-melting-point metal in whole thermal-arrest panel and heat collector cavity can be made more equal Even, temperature difference is small.The hot chamber 210 of stirling generator is immersed in liquid low-melting-point metal, and it is right that liquid low-melting-point metal passes through Stream heat exchange efficiently passes to heat in the hot chamber of stirling generator, improves the generating efficiency of stirling generator.
