PURPOSE:To permit direct heat exchange between first and second heat medium or the same between latent heat accumulating material, in which heat is accumulated previously, and the second heat medium by a method wherein the latent heat accumulating material, whose latent heat upon melting or solidifying at normal temperature can be utilized, is packed between the transversal fins of a heat absorbing pipe, filled with the first heat medium, while lateral fins, forming a space for packing the latent heat accumulating material at a part whereat the transversal fins are contacted with the latent heat accumulating material, is provided to provide the second heat medium around the transversal fins. CONSTITUTION:When the temperature of latent heat accumulating material 3 <= the solidifying point of the same material < the temperature of heat medium B under a condition that the heat medium A is not supplied, the latent heat accumulating material 3 causes sensible heat change and latent heat change by a temperature difference between the heat medium B under utilizing a contacting part 6 between the transversal fins 2 of the latent heat accumulating material 3 and the heat medium B as a heat transfer surface and is cooled by the heat medium B. On the other hand, when the temperature of the latent heat accumulating material 3 >= the melting point of the latent heat accumulating material 3 > the temperature of the heat medium B, the latent heat accumulating material 3 causes latent heat change and sensible heat change by the temperature difference between the temperature of the heat medium B under utilizing the containing part 6 and the lateral fins 4 as the heat transfer surface and dissipates the heat thereof into the heat medium B. |
