PURPOSE:To take necessary measure to the volume expansion of a heat accumulating material and obtain the capsule enclosed with a heat accumulating material having high anti-corrosion and heat exchange efficiency by a method wherein many grooves are formed on the surface of a cube-shaped capsule made of synthetic resin. CONSTITUTION:Many grooves 2 used for the flow channel of a water is formed on the surface of a nearly cube-shaped capsule 1. Those grooves 2 are formed to be circulated around the capsule 1, accordingly, the stagnancy of the water does not occur. Many grooves 2 act for widening the surface area of the capsule 1. A latent heat family heat accumulating material 3 is filled in the capsule 1. In case of the operation, for instance, at approximate 30 deg.C in temperature, inorganic materials such as CaCl2.6H2O, Na2HPO4.12H2O, Na2SO4. 10H2O and the like, and organic materials such as paraffin, polyethylene glycol and the like are utilized as the latent heat family heat accumulating material having the fusion point of approximate 30 deg.C. The capsule is formed of synthetic resin material such as a polyethylene and the like enabled to cope with the volume expansion of the latent heat family heat accumulating material. |
