PURPOSE:To contrive a higher heat exchanging efficiency in heating a heat storage material and in extracting stored heat from the heat storage material by providing a communication pipe of a heating medium for heating a heat storage material which pierces through plate fins and is fixed to them and a heat pipe which locates respectively an evaporation section and condensation section near the heating medium communication pipe for absorbing the stored heat. CONSTITUTION:A heat exchanger 3 which is provided in a latent heat storage material 2 in a heat storage tank 1 is provided with parallel aluminium plate fins 4, a lower section copper heat storage material heating heating medium passage pipe 5 which pierces and fixed through and by the fins 4, and an upper copper storage heat absorbing heating medium passage pipe 6. With this constitution, the heat transfer area between the heat storage material heating heating medium and the heat storage material 2, and the heat transfer surface area between the water and heat storage material 2 become larger. Further, because a heat pipe 7 is provided in fins 4 so as to locate the evaporation section near the pipe 5 and the condensation section near the pipe 6, it becomes easy for the heat in the heating medium to be transmitted all over the fins 4 and for the heat storage material 2 it becomes difficult to solidify. Accordingly the heat exchanging efficiency in heating the heat storage material and extracting heat therefrom is enhanced. |
