摘　　要：提出了一种用于硫酸行业的板翅紧凑型转化器 ,通过实验对采用不同翅高时流道内的传热与流阻性能进行了研究 .结果表明 ,随着流道内翅片高度的增大 ,传热膜系数随之增大 ,但流阻曲线则呈凹型变化 ,即在中间高度时流阻达到一最小值 .A type of compact plate_fin reactor with inner heat exchangers for sulphur dioxide conversion was proposed. Heat transfer and resistance properties of this reactor with different fin scales are experimentally studied. It is found that heat transfer coefficient increases with fin height, while flow resistance varies as concave curve, that is to say, the resistance reaches the lowest value at a middle fin height. This flow phenomenon is analyzed through numerical calculation in this paper.
