摘要
This paper utilizes numerical analysis method to determine the influence of non-condensation gas on the thermal performance of a heat pipe. The temperature difference between the evaporation and condensation sections of a single heat pipe and maximum heat capacity are the index of the thermal performance of a heat pipe for a thermal module manufacturer. The thermal performance of a heat pipe with lower temperature difference between the evaporation and condensation sections is better than that of higher temperature dif- ference at the same input power. The results show that the maximum heat capacity reaches the highest point, as the amount of the non-condensation gas of a heat pipe is the lowest value and the temperature difference between evaporation and condensation sections is the smallest one. The temperature difference is under 1?C while the percentage of the non-condensation gas is under 8 × 10?5%, and the heat pipe has the maximum heat capacity.
