<P>PROBLEM TO BE SOLVED: To secure an air flow passage even if an outward expansion of a first and a second wall surfaces with the lapse of time is generated by the weight of the thermal storage medium in a thermal storage capsule formed with recessed parts and projecting parts each other in the first and the second wall surfaces to form an air blowing passage. <P>SOLUTION: In this thermal storage capsule, an inner space 3 to be filled with the thermal storage medium is formed between the first wall surface 1 and the second wall surface 2 arranged opposite to each other. Each of the first wall surface 1 and the second wall surface 2 is formed with recessed grooves 7a recessed to the inner space 3 side and projecting parts 7b swelled to a side opposite to the inner space 3. The recessed groove 7a of the first wall surface 1 and the projecting part 7b of the second wall surface 2, and the projecting part 7b of the first wall surface 1 and the recessed groove 7a of the second wall surface 2 are formed at positions corresponding to each other with a view in a normal direction of the first wall surface 1 or the second wall surface 2. In the thermal storage capsule with this structure, width dimension of a tip of the projecting part 7b is set at a value larger than the width dimension of a bottom surface of the recessed groove 7a. <P>COPYRIGHT: (C)2003,JPO |
