在實際運作上，當真空管本體21曝曬在陽光底下時，太陽光線會穿過透明的真空管本體21而照射至太陽熱能吸收元件23，使太陽熱能吸收元件23吸收太陽光線的熱能，進而透過固定框體22之平板本體部221將熱能傳遞至溫差發電晶片3之熱端31，另一方面，由於溫差發電晶片3之冷端32是熱連結於流體循環管路41，且流體循環管路41還延伸至散熱元件42，因此充填於封閉流道411內之相變材RG會持續地將冷端32之熱量帶走，使熱端31與冷端32產生一溫度差而使溫差發電晶片3發電。In actual operation, when the vacuum tube body 21 is exposed to sunlight, the sun’s rays will pass through the transparent vacuum tube body 21 and irradiate the solar heat absorbing element 23, so that the solar heat absorbing element 23 absorbs the heat energy of the sun’s rays, and then passes through the fixed frame The plate body portion 221 of body 22 transfers thermal energy to the hot end 31 of thermoelectric power generation chip 3. Extending to the heat dissipation element 42, the phase change material RG filled in the closed flow channel 411 will continuously take away the heat of the cold end 32, so that a temperature difference between the hot end 31 and the cold end 32 will be generated to make the thermoelectric power generation chip 3 generate electricity .

承上所述，在本實施例中，每個真空管本體21內的溫差發電晶片3更可將電力由真空管本體21之端部引導至一儲電裝置200，藉以有效地將太陽熱能轉換為電力進行儲存。Based on the above, in this embodiment, the thermoelectric power generation chip 3 in each vacuum tube body 21 can lead the electric power from the end of the vacuum tube body 21 to a power storage device 200, so as to effectively convert solar heat into electricity to store.

此外，本實施例之流體循環管路41內所充填之相變材RG可以是透過自然溫差的方式在流體循環管路41內流動而形成自然循環，但不限於此，在其他實施例中亦可另外裝設有幫浦來加速相變材RG的流動速度。In addition, the phase change material RG filled in the fluid circulation pipeline 41 of this embodiment can flow in the fluid circulation pipeline 41 through natural temperature difference to form a natural circulation, but it is not limited thereto, and it can also be used in other embodiments. A pump can be additionally installed to accelerate the flow velocity of the phase change material RG.

綜上所述，本發明之真空管溫差發電裝置主要是在真空管本體內設有太陽熱能吸收元件來吸收太陽熱能，並將太陽熱能傳遞至溫差發電晶片之熱端，且本發明還利用相變材管路組件來對溫差發電晶片之冷端進行降溫，藉以有效使溫差發電晶片之熱端與冷端可以產生溫差而發電；相較於先前技術之太陽能發電大都需要透過太陽能面板進行發電，而太陽熱能的吸收與儲存僅應用於熱水器，本發明透過簡單的構造即可有效的利用太陽熱能進行發電，而不需使用製程複雜的太陽能面板，藉此本發明之真空管溫差發電裝置確實具有構造簡單且低成本的功效。In summary, the vacuum tube thermoelectric power generation device of the present invention is mainly provided with a solar heat absorbing element in the vacuum tube body to absorb solar heat, and transfer the solar heat to the hot end of the thermoelectric power generation chip, and the present invention also utilizes a phase change material Pipeline components are used to cool down the cold end of the thermoelectric chip, so that the hot end and the cold end of the thermoelectric chip can generate temperature difference to generate electricity; Energy absorption and storage are only applied to water heaters.
