摘要
针对普通套管式换热器的不足 ,设计了套管式折流杆管束换热器壳程内部结构。对不同内部支承结构与管束组合的套管式管束换热器壳侧进行了传热与流阻性能实验研究 ,得到了 3种换热器壳侧对流传热系数及压降随流量变化的关系曲线。实验结果表明 ,套管式折流杆螺旋槽管束换热器壳侧具有较好的传热与流阻性能。
The practical structure in shell-side of RODbaffle multi-tube type of double-tube heat exchanger has been designed to overcome the deficiencies of conventional double-tube heat exchanger. The heat transfer and flow resistance performance of heat exchangers with smooth or roughen tube bundles supported by rod or plate supports have been investigated through experiments, and the curves of heat transfer coefficient and pressure drop in shell-side of these heat exchangers are obtained. Experimental results indicate that the new RODbaffle double-tube heat exchanger with spiral groove tube bundles provides superior heat transfer and pressure drop characteristics and has a splendid future when applied in petroleum industry.
