Patent ID: 8253008

Claim:
A heat pipe heating AMTEC, which converts heat energy to electric energy, comprising: a case which comprises an inside that is closed and filled with a predetermined amount of a metal fluid; a heating heat pipe formed at a lower end of the case so as to be operatively connected with the case, for heating the metal fluid in the inside of the case and vaporizing the metal fluid into vapor; a condenser circulation wick installed above the heating heat pipe that protrudes in the inside of the case, for collecting the metal fluid vapor vaporized by the heating heat pipe and guiding the metal fluid vapor in one direction; a number of BASE (beta alumina solid electrolyte) tubes installed radially around the center of the case, for allowing the heated metal fluid vapor guided by the condenser circulation wick to pass and generate electricity; and a condenser formed at a top of the inside of the case, for collecting and condensing the metal fluid vapor passed through the BASE tubes; wherein the condenser circulation wick connected to the condenser comprises: an insertion opening with at least a portion of the heating heat pipe being positioned therein inside of the condenser circulation wick; and a number of groove wicks formed in a circumferential direction of the insertion opening, for guiding the metal fluid vapor vaporized by the heating heat pipe in one direction; and wherein the heating heat pipe comprises: a vaporization part for vaporizing an operating fluid inside of the heating heat pipe by heat applied from outside of the heating heat pipe, the vaporization part comprising a number of pins formed to pass through the vaporization part and to be perpendicular to the heating heat pipe, so that the outside heat is transferred to the inside of the heating heat pipe; a transfer part for transferring the operating fluid vapor vaporized in the vaporization part; and a condensation part for condensing the operating fluid vapor transferred through the transfer part by transferring heat to the outside of the heating heat pipe, the condensation part being positioned inside the insertion opening of the condenser circulation wick, the condensation part comprising a number of groove wicks on the heat pipe formed in a circumferential direction of the condensation part, so that the inside heat of the heating heat pipe is transferred to the inside of the case and the metal fluid vapor is guided in one direction.
