摘　　要：进行了液氮温区小型轴向槽道热管传热性能的实验研究。实验结果表明,低温热管具有一定的传热能力,热管轴向温差小,热阻小;低温热管在小倾角抗重力情况下也能工作,并且倾角对热管传热性能有重要影响。The heat transfer characteristic experimental studies of the small axially grooved heat plpe working at the liquid nitrogen temperature range were presented. It was proved that the cryogenlc heat pipe had some heat transfer capacity. The endtoend temperature drop was small and the overall thermal resistance was also small; the heat pipe could successfully work under small angles with the evaporation end up. The gradient angle had important effect on the heat transfer characteristics.
