摘要： 以阳煤二矿南风井井口防冻应用整体式热管换热技术为例，根据井口防冻热负荷和矿井回风余热的供热能力，对热管换热器基本参数和热管阻力进行了设计计算。经过统计一个采暖季的数据，分析了典型工况下矿井回风、新风在换热前后的温度变化情况。结果表明：应用热管换热技术可以满足井口防冻的热需求，当最低温度-15℃接近设计最低值时，进风温度2.2℃也能达到预期目标。

Abstract: Based on integrated heat pipe heat exchange technology coal mine well wellhead heating was researched as a case study in Second mine south wind well of Yangquan coal Industry Group. According to the parameters of thermal load of wellhead ventilation and the residual heat of mine air, the basic parameters of heat pipe and heat pipe resistance were calculated to analysis the temperature of the mine return air and fresh air before and after the heat exchange under typical operating conditions. The results show that the application of heat pipe heat transfer technology can meet the thermal demand of anti-freezing at the wellhead. When the outdoor temperature closing to the design value is -15℃, the inlet wellhead air temperature is 2.2℃.
