THERMAL STORAGE DEVICE, STRUCTURE AND PROCESS OF MANUFACTURE OF THERMAL STORAGE DEVICE

PROBLEM TO BE SOLVED: To perform a positive encapsulation of a place where a phase change material is flowed in after the phase change material is flowed in.SOLUTION: A thermal storage panel 1 of this invention comprises a front plate 11 that is a member heat exchanged with outside part, a frame body 13 and a rear plate 17 forming storing spaces 139 among the front plate 11 and the frame body 13 and the rear plate 17, and phase change material stored in the storing spaces 139 and showing phase change by heat exchanged with the outside. Further, this thermal storage panel 1 has a through-pass hole 138 arranged at the frame body 13, a first through-pass hole 138A and a second through-pass hole 138B for guiding the phase change material pored from outside into the storing spaces 139 and sealed after this guiding action, and a third through-pass hole 138C and a fourth through-pass hole 138D for discharging air in the storing spaces 139 to the outside when the phase change material flows into the storing spaces 139 through the first through-pass hole 138A and the second through-pass hole 138B and sealed after this discharging action. 【課題】相変化材を流入させる箇所を相変化材の流入後に確実に封止する。【解決手段】本発明の蓄熱パネル１は、外部と熱交換する部材である表板１１と、表板１１との間に収容空間１３９を形成する枠体１３および裏板１７と、収容空間１３９に収容され外部と交換される熱により相変化する相変化材とを備える。さらに、この蓄熱パネル１は、枠体１３に設けられる貫通孔１３８であり、外部から収容空間１３９内に注入される相変化材を案内し、この案内後に封止される第１貫通孔１３８Ａおよび第２貫通孔１３８Ｂと、第１貫通孔１３８Ａおよび第２貫通孔１３８Ｂを介して収容空間１３９内に相変化材が流入する際、収容空間１３９内の空気を外部へ排出し、この排出後に封止される第３貫通孔１３８Ｃおよび第４貫通孔１３８Ｄとを備える。【選択図】図２
