介绍了泥浆制冷系统及同轴套管式换热器的结构与工作原理,采用传热计算和传热数值模拟分析方法,对光管式换热器与螺纹管式换热器从传热系数和换热面积进行对比分析研究.对比分析结果表明,在满足水合物钻探取样的条件下,螺纹管式换热器可增大换热面积,从而使螺纹管式换热器的体积和质量较光管式换热器可减少50%~60%,在相同规格条件下,螺纹管式换热器的换热效率大约是光管式换热器的2~3倍.

This paper introduces the structure and working principle of mud refrigeration system and coaxial pipe heat ex-changer.By the means of the theoretical analysis and numerical simulation, analysis comparative research is made on heat transfer coefficient and heat exchange area of light pipe heat exchanger and thread tube heat exchanger, the results show that the threaded pipe type heat exchanger can increase the heat exchange area when the hydrates drilling sampling condi-tions are provided, so that the volume and weight of threaded pipe type heat exchanger can reduce 50%~60%comparing with that of light tube heat exchanger.Under the same specification conditions, the heat transfer efficiency of threaded pipe type heat exchanger is about 2~3 times of light tube heat exchanger.
