用环形热管减少机床的热变形

REDUCING THE THERMAL DEFORMATION OF MACHINE TOOLS BY CIRCULAR HEAT PIPE

论述了环形热管的原理、结构和换热计算方法。试验结果表明，这种热管不但能降低主轴轴承的温升，而且可大大提高主轴轴线的热稳定性，从而提高机床的加工精度。

The principle, structure and beat exchange of a circular heat pipe system are presented. The testing results showed that the rise-temperature of spindle bearings can be reduced, the thermal stability of spindle axis and the machining accuracy of machine tool can also be improved.
