Cylindrical heat pipe
WebThe principle of operation of a simple cylindrical heat pipe is shown schematically in Fig. 2.1. The wick is saturated with a wetting liquid. In the steady state the liquid temp-erature in the evaporator is maintained higher than in the condenser by an external heat source. The resulting difference WebApr 1, 2024 · A two-dimensional conventional cylindrical heat pipe configuration is presented in Fig. 1. The heat pipe includes three separate regions, the evaporator, adiabatic, and condenser sections, which are subject to different boundary conditions.
