摘要
建立了热电制冷器通风及耦合换热数学和物理模型,模拟计算了不同雷诺数、材料有效导热系数比率、几何参数时各通道的流体流动及温度场分布情况,分析了冷风侧排风、几何参数对通道换热能力的影响,以优化制冷器通风换热风道的设计参数。
Establishes the mathematic and physical model of ventilation and conjugate heat transfer of thermoelectric refrigerators. Simulates the fluid flow and temperature field of multi air ducts in different Reynolds numbers, effective conduction coefficient and geometric ratio. Analyses the effect of the exhaust air rate in cold side and geometric ratio on heat transfer of ducts in order to optimize the design parameters of air ducts.
