As the demand for high performance small electronic devices has increased , heat removal
from these devices for space use is approaching critical limits . A heat pipe is a promising
device to enhance the heat removal performance due to the phase change phenomena for
space thermal management system . Even though a heat pipe has a big potential to remove
the thermal energy from a high heat flux source , the heat removal performance of heat
pipes cannot be predicted well since the first principle of evaporation has not been
established . The purpose of this study is to establish a method to apply the evaporation
model based on the statistical rate theory for engineering application including
vapor -liquid -structure intermolecular effect . The evaporation model is applied to the heat
pipe performance analysis through a pressure balance and an energy balance in the loop
heat pipe . |
