Abstract

PURPOSE:To prevent the heat accumulating capsule utilizing a non-elastic body material from bursting at the rapid local heating by a method wherein a volume increase content caused by the expansion of a local fusion is introduced to an air layer part prepared previously in a capsule. CONSTITUTION:An inclusion 3 formed of a cylindrical fluororesin family material having a thin section is arranged on the inner periphery wall of a cylindrical non-elastic body capsule 1. In case of rapid local heating H at the lower side of the capsule 1, a liquid phase part 2b is produced by the fusion of a part of a solid phase part 2a of a heat accumulating meterial 2, then the volume of the liquid phase 2b is increased approximate 10%. The inclusion 3 has extremely inferior adhesion property for other object, also non-adhesion, a little coefficient of friction, a little sliding friction and elasticity, consequently, the volume expansion content of the liquid phase part 2b is flowed toward either A or B direction, or both directions, along the boundary between the solid phase part 2a of the heat accumulating material and the inclusion 3, escapes to a previously prepared air layer area 4 at the upper part of the capsule. Therefore, abnormal liquid pressure rising caused by the volume expansion of the melted liquid phase part 2b is not produced, accordingly, the non-elastic body capsule 1 can be prevented from the bursting.

This relates to heat storage capsules.

は、耐食性。In response to social demands for energy conservation, heat storage materials are being developed, and in particular, the development of latent heat type heat storage materials that utilize the latent heat generated during solidification and melting of substances is progressing. On the other hand, regarding the capsules that house the heat storage material, heat storage capsules for relatively high temperatures that use corrosive salt compounds as the heat storage material are corrosion resistant.

った。However, if heat is suddenly applied to the inelastic capsule,
There is a problem in that the capsule locally cracks. The reason for this is that even if the heat storage material melts locally, the unmelted part is in close contact with the inner wall of the capsule, so the melted part becomes a sealed structure, and as a result, the melted heat storage material expands by 1 volume, and as a result Unusual pressure is applied, and since the capsule is inelastic, it cannot absorb volume expansion due to deformation.
It has cracks. It should be noted that if the capsule has a wall thickness that can withstand this pressure increase, the size of the capsule would become too large to be practical. This polishing made it impossible to use a non-elastic capsule material, and there was a drawback in that the materials that could be applied to this type of capsule were severely limited.

Its purpose is to provide a heat storage capsule that is free of heat.

るようにしたものである。The structure of the heat storage capsule according to the present invention is that the heat storage capsule is composed of a heat storage system having the same phase and liquid phase and a non-elastic capsule that houses the heat storage material, in which the inelastic capsule and the heat storage material are A third member with a small coefficient of friction and adhesiveness is interposed at the boundary, and a local negative air region is provided in the region of the previous ml heat storage material to prevent volume expansion due to local melting of the heat storage material. The air can be released into the air layer region.

かかることもなく、カプセルの破裂の心配もない。In addition, it should be noted that heat input to the heat storage cube hill takes place from the outer periphery of the capsule, melting also starts from the boundary between the capsule and the heat storage material, and even if volume expansion occurs due to local melting, this volume increment is calculated in advance by semi-flattening. If the gas can be easily introduced into the entire air layer within the capsule, there will be no local pressure rise and the capsule will not burst. In short, if the density of the heat storage material that is in phase with the capsule is made extremely poor, and a layer with micrograve deformation is present at the boundary between the two, the occurrence of a state in which the molten part is sealed in any local area can be prevented. The volumetric expansion of the heat storage material due to melting can be easily led to the extinct layer inside the capsule through the boundary between the inclusion and the heat storage material. Therefore, no abnormal pressure is locally applied to the lower surface of the capsule, and there is no fear of capsule rupture.
