Abstract
This paper reports test results and evaluation of a long-distance loop heat pipe (LLHP) with 10 m distances for heat transport. The LLHP could transport heat up to 290 W for 10 m and a thermal resistance between evaporator and condenser was 0.11 K/W. The heat transfer efficiency of the LLHP was discussed more in detail. The results showed that 76.8% of the 240W heat load was dissipated at the condenser line under the condition of no gravitational effect. On the other hand, 73.0% of the 240W heat load was dissipated at the condenser under 30 cm anti-gravitational condition.
