PURPOSE:To improve the heat transfer property of the titled device by a method wherein ventilating members are provided among metallic members arranged in a heat accumulating material within a vessel so that air bubbles generating in the heat accumulating material is introduced into the space in the upper part of the interior of the vessel. CONSTITUTION:The ventilating members 6 each in the form of a pipe 8 having a number of holes 7 are arranged among the metallic members 3 made of copper, aluminum or the like and arranged in the heat accumulating material 2 so as to increase the heat transfer efficiency. The air bubbles generating in the heat accumulating material 2 pass through the pipe 8 via the holee 7 and reaches the space 4 above the level 2' of the liquid heat accumulating material 2. As a consequence, the air bubble do not stagnate among the metallic members 3 and therefore, the heat trnasfer property of the heat accumulating device is not spoiled. |
