PURPOSE:To improve transfer ability of heat from a heat accumulating material to a heat-exchanger by a method wherein a heatexchanger is mounted is thermally coupled to a container for containing a granular heat accumulating substance and a means to control the flow of evaporative liquid is arranged therebetween. CONSTITUTION:When a heater 25 is energized, liquid 6 in it is boiled, and air bubbles generated by the boiling are raised through buoyancy. Along with the rise of the air bubbles, liquid in a rise pipe 24 is pumped up through pumping operation of the air bubbles and flows over the top part of the rise pipe 24. The liquid 6 flows in a vaporizer 21 after the flow of it through a liquid return pipe 23, and heat is imparted thereon by heat accumulating substances 4 for vaporization. The steam flows through a steam moving pipe 22 to a condenser 20 and after the steam is caused to emit a condensing heat by a heat-exchanger 2 part and liquefied and dropped, the same cycle is repeated. A pressure uniforming pipe 26 is served to return steam, generated in the rise pipe 24, to the condenser 20. By regulating an input to the heater 25, a quantity of heat transported from the heat accumulating substance 4 to the heat-exchanger 2 is controlled. |
