针对常用的陶瓷蓄热小球流动阻力大、蜂窝陶瓷蓄热体平行独立直通道间气流分布不均匀的缺点,提出一种前后、上下、左右通孔垂直相交贯通的新型蓄热体结构,并分析通孔结构、通孔尺寸对蓄热体换热比表面的影响规律。分析结果表明,通过调整新型蓄热体的通孔结构与尺寸能够达到常规蓄热体换热比表面积的要求。
Aiming at the shortcoming of the common ceramic regenerative pellets with large flow resistance and uneven distribution of air flow between the independent and parallel honeycomb ceramic regenerators, a new regenerator structure with vertical and horizontal through holes is proposed The influence of through-hole structure and through-hole size on heat exchange surface area of regenerator was analyzed. The analysis results show that the heat exchanger specific surface area of the conventional regenerator can be achieved by adjusting the through-hole structure and size of the regenerator.
