PURPOSE:To obtain a flexible heat storing element which does not form any big agglomerates of a heat storing material during usage thereof, by encapsulating a blend of a heat storing material, a thickening agent, and a carrier material carrying these upon hardening thereof with an encapsulating material. CONSTITUTION:A heat storing element 1 is obtd. by blending a heat storing material, a thickening agent 2 and a carrier material 3 carrying the heat storing material and the thickening agent 2 upon hardening thereof and encapsulating the resultant blend with an encapsulating material 4 so as to attain integration of the blend and the encapsulating material 4. In the production of the above- mentioned blend, it is pref. that a thickening agent be added to a molten heat storing material, followed by sufficient agitation and then hardening, and that the mixture be pulverized into fine particles, followed by blending of the particles with a liq. carrier material 3. A suitable example of the heat storing material is a compsn. comprising paraffin or a salt, such as sodium sulfate decahydrate or sodium acetate trihydrate, and a nucleating material. Examples of the thickening agent include alumina, silica, polyvinyl alcohol, etc. Pref. examples of the encapsulating material are woven and non-woven fabrics of a flexible fibrous material. |
