ABSTRACT:
A fast acting fusing method and apparatus are provided for (a.) first moving a certain quantity of working liquid within a fusing heat pipe device from a heat transferring region of the fusing heat pipe device to an induction heating region of the fusing heat pipe device for maximizing liquid-to-device wall contact area within the induction heating region; (b.) using inductor heating coils to apply heat to the induction heating region of the fusing heat pipe device for heating the working liquid within the induction heating region; (c.) allowing heated vapors from the working liquid being heated within the induction heating region to move into the heat transferring region of the fusing heat pipe device for heating the heat transferring region; (d.) using a controller to compare heating of the heat transferring region of the fusing heat pipe device to a given heating value; and (e.) next moving the certain quantity of working liquid back from the induction heating region to the heat transferring region when heating of the heat transferring region of the fusing heat pipe device reaches the given heating value.
