摘要
采用辐射热阻网络方法建立了热光伏(TPV)系统的辐射换热模型,并指出不考虑石英玻璃管对辐射光子可能的波长转换作用会导致计算所得的石英玻璃管的光谱发射功率密度与普朗克定律相违背。采用添加单色波热源的方式对辐射换热模型进行了修正,得到了系统的辐射热流密度、光谱效率和石英玻璃管的等效辐射温度等一些重要参数,与参考文献中结果吻合较好。
The radiation heat transfer model for thermophotovoltaic system was constructed by applying the radiation resis- tor network method. However, no consideration of the wavelength shift in the quartz envelope will lead to the discrepancy between the evaluated spectral emissive power of the quartz envelope and the Plank law result. Therefore, a modified spectral radiation network in which the wavelength shift effect was expressed as the form of spectral heat source was devel- oped. Several important parameters were figured out from the modified model, including the spectra radiation power, spectra efficiency of the system and equivalent radiative temperature of the quartz envelope. The simulated results indicat- ed that the modified model shows better coherence with reference.
