PURPOSE:To make the effective use of a heat accumulating material by a method wherein a heat accumulating material whose phase changes from solid to liquid is provided in close contact with the outer periphery of a heat pipe at a predetermined section over a predetermined length and the heat accumulated by the heat accumulating material is taken out into a predetermined heat absorbing source so that the action of the heat accumulating material utilizing latent heat is brought under as desirable a condition as possible. CONSTITUTION:The heat pipe 1 is lined with a wick 2 on the inner peripheral surface thereof and a suitable operating liquid is sealed therein. The heat accumulating material 4 whose phase changes from solid to liquid is sealed into a sealed vessel 3 provided above the outer periphery of one end of the heat pipe so as to surround that end and the heat accumulating material 4 is closely attached to the outer peripheral surface of the heat pipe 1 over a predetermined length. The heat supplied to the other end of the pipe from a heat source H is connected to one end of the pipe as latent heat by means of an operating fluid within the heat pipe 1 so that the heat accumulating material 4 is fused by the heat and stores the heat as latent heat. In this case, as the heat accumulating material 4 is in contact with the heat pipe over a wide surface area in the heat exchanger, the heat accumulating material 4 is not overheated locally but is fused almost uniformly. |
