MATHEMATICAL MODELING OF STEADY-STATE OPERATION OF A LOOP HEAT PIPE WITH NOVEL EVAPORATOR
In this paper, a loop heat pipe (LHP) with novel evaporator is proposed, which features very small heat leak from the evaporator to the compensation chamber (CC), which can improve the operating stability and reliability of the LHP.The mathematical model of steady-state operation of the LHP with novel evaporator is established, and its operating characteristics and heat transport limit have been theoretically analyzed.The major conclusions below have been drawn: (1) the heat leak from the evaporator to the CC for the LHP with novel evaporator is far smaller than that of traditional evaporator;(2) the liquid flow pressure drop in the evaporator wick occupies the most part of the total pressure drop of the LHP with novel evaporator, and further study should be conducted to reduce it;(3) when the adverse elevation is small, the heat transport limit of the LHP with novel evaporator is dominated by the boiling limit, whereas when the adverse elevation is comparativelylarge, it is dominated by the capillary limit.
