    • A vapor-lift pump heat transport apparatus having a small heat resistance and a large heat transport capacity. A heat exchange circulating solution container has a first space and a second space communicating with the first space through a communication opening and contains a heat exchange circulating solution, and vapor thereof, in each space. A circulating solution transport passage includes a pipe connected to the solution outlet of the container and provided with a sensible heat releasing heat exchanger, a pipe disposed in the container, and a pipe connected to a vapor-liquid two-phase fluid inlet and provided with a heating heat exchanger. A vapor-liquid two-phase fluid flows into only the first space through the vapor-liquid two-phase fluid inlet. When the entrance of the vapor-liquid two-phase fluid has caused a pressure difference between the first and second spaces, a difference occurs between the positions of the vapor-liquid interfaces in the first and second spaces.
