A heat pipe having a turbine built therein includes a vertically oriented, closed tube containing working fluid therein, a hollow taper tube rotatably disposed within the closed tube and having an increasing diameter toward the upper end, and turbine blades attached to the outer periphery of the hollow tube at its intermediate wherein the upper and lower end of the closed tube are heated and cooled, respectively, to create a flow of vapor-phase working fluid through the closed tube to thereby rotate the turbine blades and the hollow tube, and liquid-phase working fluid is fed upward through the hollow tube by the resultant centrifugal force. An apparatus using such a turbine-equipped heat pipe can perform heat transport and electric power generation at the same time by attaching turbine blades to a rotary shaft rotatably supported in the closed tube such that the blades are driven by a flow of vapor-phase working fluid and coupling the rotary shaft with a generator disposed outside the closed tube. |
