潜熱蓄熱体

PURPOSE:To permit the forming of a latent heat accumulating body, small in heat loss and miniaturized compactly as a whole, by a method wherein an inlet pipe and an outlet pipe are provided with a vertical zone respectively while both of them are designed so as to have heat insulating property. CONSTITUTION:The vertical areas 26 of an inlet pipe 12 and an outlet pipe 14 are guided to the outside of an outside housing 28 so as to cross the cylindrical surface area 32 of the outside housing 28 and the outside housing 28 is extended axially than the end surface 20 side at the position of the end surface 18 of an inside housing 10 while one part of a heat insulating chamber 30 is formed so as to be capable of being penetrated by the inlet pipe 12 and the outlet pipe 14 to lead them out and a heat accumulating body is provided with a very simple profile consisting of two connected bodies 34, 36 projected out of the cylindrical outside housing 28 and the surface area 32 of the outside housing 28. The end face 42 of the outside housing 28, neighboring to the end face 18 of the inside housing 10, crosses the inlet pipe 12 and the outlet pipe 14 in the area of the horizontal part 22 thereof and the end face 42 is provided with an opening 44 while the rim 46 of the opening 44 is separated from the inlet pipe 12 and the outlet pipe 14 by a corresponding at least to the necessary thickness of an insulating formed of the heat insulating chamber 30.
