1. An vapor-lift pump heat transport apparatus comprising:

  • a heat exchange circulating solution container that contains a heat exchange circulating solution and vapor of the heat exchange circulating solution;

    solution outlets through which the heat exchange circulating solution is output from the container;

    a vapor-liquid two-phase fluid inlet through which a vapor-liquid two-phase fluid consisting of a high-temperature heat exchange circulating solution and vapor bubbles of the high temperature heat exchange circulating solution are input to the container;

    an opening in a top portion of the container and communicating with an environmental space of the container; and

    a circulating solution transport passage having a first transport passage connected to the solution outlet and including a sensible heat releasing heat exchanger, a second transport passage through which an internal, low-temperature heat exchange circulating solution exchanges heat with the heat exchange circulating solution in the container or the heat exchange circulating solution and its vapor in the container, and a third transport passage connected to the vapor-liquid two-phase fluid inlet and including a heating heat exchanger, each of the first and third transport passages being connected to the second transport passage, whereinthe vapor-liquid two-phase fluid inlet is disposed in a central portion of the container,solution outlets are disposed on opposite sides of the vapor-liquid two-phase inlet, on a lower portion of the container, andbranches of the first transport passage are connected to respective solution outlets and merge into a trunk passage that is connected to the second transport passage.
