摘要
通过对等长对流增速Ｕ型管井下换热器的分析，建立了理论模型，导出流动控制方程和增速管入口无混合流和有混合流时的环流控制方程，可确定环流量及有关温度参数。
onvector pipe is used to enhance the circulation of geothermal fluid in the well where downhole heat exchanger is equipped. A model for downhole heat exchanger with the convector pipe which has the same length as the exchanger is established.Circulation equations are derived for determining the circulation flowrate and temperature in this kind of downhole heat exchanger.
