摘要
基于单层金属网的能量平衡,建立了分析多层金属网吸热体太阳能空气加热器热性能的稳态数学模型。利用这一数学模型,分析了金属网结构尺寸、金属网层数及辐射特性对加热器性能的影响。计算结果可供设计时参考。
Based on the energy balance principle to a single layer of wire gauze,a steady state thermal performance model for multi-layer wire gauze absorber is established.The effect of struetare size,number of layers and radiation properties of the wire gauze on solar air heater are analysed.
