Japanese Patent JP5994209

Kind Code:

B2

Abstract:

PROBLEM TO BE SOLVED: To provide a heat accumulation device capable of effectively preventing degradation of heat accumulation characteristics, and keeping durability, and easy in maintenance inspection.SOLUTION: A heat accumulation device 16 has a heat accumulation container 3 filled with a latent heat utilization heat accumulation agent 2, a metallic heat exchanger 6 in which a heat medium fluid flows, and which has an outer peripheral face configuring a heat transfer face between the heat accumulation agent and the heat medium fluid, is disposed in the heat accumulation container 3, and further a drop-lid 9 having a specific gravity smaller than the heat accumulation agent so that it is floatable on a liquid-phase heat accumulation agent in a state of projecting upward from a liquid level of the liquid-phase heat accumulation agent. The drop-lid 9 is slidably engaged with an inner peripheral face of the heat accumulation container 3 at a peripheral side face 30 of the drop-lid so that it is vertically movable while floating according to volume fluctuation of the heat accumulation agent. The metallic heat exchanger is disposed while liquid-tightly penetrating through a side face or a bottom face of the heat accumulation container 3, and provided with airtightness adjusting means 4 for adjusting airtightness between the peripheral side face of the drop-lid 9 and the inner peripheral face of the heat accumulation container 3.SELECTED DRAWING: Figure 1
