    Abstract: A prototype two-phase reverse-loop thermosyphon (RLT) was fabricated to transport thermal
    energy downwards to a thermal storage tank. The effect the filling ratio exerted on the thermal
    performance of the RTL was investigated by conducting experiments that were performed by a range
    between 47% and 63%. The prototype device comprised an evaporator, a condenser, a reservoir
    (preheater), and pipes connecting each of the components. The heat transport height was 1500 mm
    from the evaporator to the bottom of the condenser. Methanol with a concentration of 95% was used as
    the working fluid. The temperature distribution, temperature difference between the evaporator and
    condenser, and thermal resistance of the thermosyphon were measured. In addition, a cyclic case, in
    which the power in coils was alternately switched on and off according to a square wave function was
    studied. The results indicated that the maximal thermal performance of the RLT occurred when the
    filling ratio was 60% and the input power was 660 W
