PURPOSE:To improve the durability of a heat radiation fin and the thermal input and output through the fin by loading to respective pipe sections of a snaky heat transfer pipe through which a coolant flows heat radiation fins which are respectively independent and formed separately from the heat transfer pipe, and furthermore divided into a plurality of sections along the circumference of the heat transfer pipe. CONSTITUTION:A heat radiation fins 14 are provided mutually independently at respec tive pipe sections 13a-13e of a snaking heat transfer pipe 13, and each fin is divided into a plurality of sections along the circumference. Now, each section 21 of the divided heat radiation fin 14 is in the form of a rectangular paper sheet and an end of each rectangular section 21 is fixed on the pipe sections 13a-13e of the snaky heat transfer pipe 13 by an adhesive. In the arrangement above described when a heating medium which enters the snaky heat transfer pipe 13 from an inlet section 15 flows successively through the pipe sections 13a, 13b,...13e towards the outlet section 16, the latent heat accumulating material 12 develops phase transformation successively along with the flow of its heating medium. Here, because the section of the heat radiation fins 14 which are respectively fixed on each pipe sections 13a-13e are mutually independent, no abnormal force is exterted on the heat radiation fins even if the phase transforma tion of the heat accumulating material 12 is delayed. |
