Description

上記目的を達成するため、請求項１に記載の発明では、熱媒体から受け取った熱を蓄熱し、蓄熱した熱を放熱可能な蓄熱装置であって、第１所定温度で固相と液相とに相変化することによって蓄熱あるいは放熱を行う内部蓄熱材（１０６）と、第２所定温度で固相と固相とに相変化することによって蓄熱あるいは放熱を行い、内部蓄熱材を内部に収容するように形成された外部蓄熱材（１０７）とを備え、外部蓄熱材は所定の空隙を有しており、空隙に液相の内部蓄熱材が浸透可能であることを特徴とする。 In order to achieve the above object, the invention according to claim 1 is a heat storage device capable of storing heat received from a heat medium and dissipating the stored heat, wherein a solid phase and a liquid phase are formed at a first predetermined temperature. The internal heat storage material (106), which performs heat storage or heat release by phase change, and the heat storage or heat release by phase change to the solid phase and the solid phase at the second predetermined temperature, the internal heat storage material is accommodated inside and a formed external heat storage material (107) as the external heat storage material has a predetermined gap, the internal heat storage material in the liquid phase in the gap is characterized permeable der Rukoto.

遷移金属酸化物は、外部から熱エネルギを与えられると絶縁体から金属へ変化する性質を有する。より詳細には、遷移金属酸化物では、遷移金属原子の最外殻電子間の有効クーロン相互作用が強いため、金属絶縁体転移温度より低い温度になっていると、最外殻電子が自由に動けない状態（絶縁体）となる。そして、絶縁体となっている遷移金属酸化物が、外部から金属絶縁体転移温度以上となるまで熱エネルギを与えられると、最外殻電子が自由に動ける状態（金属）となる。つまり、遷移金属酸化物は、相転移温度より低温では絶縁体となり、相転移温度より高温では金属となる。 The transition metal oxide has a property of changing from insulator to metal when heat energy is externally applied. More specifically, in transition metal oxides, the effective Coulomb interaction between the outermost electrons of transition metal atoms is strong, so the outermost electrons are free when the temperature is lower than the metal-insulator transition temperature. It can not move (insulator). The transition metal oxide which is an insulator is given a heat energy from the outside until the metal-insulator transition temperature degrees or in the state (metal) which outermost electrons can move freely. That is, the transition metal oxide is an insulator at a temperature lower than the phase transition temperature, and a metal at a temperature higher than the phase transition temperature.

図７に示す例では、ケース部材１０７の空隙率は、内部蓄熱材１０６と接する部位が最も高く、内部蓄熱材１０６から離れるにしたがって低くなっている。つまり、ケース部材１０７の内側から外側に向かって空隙率が低くなっている。ケース部材１０７において、第１熱媒体と接する部位（つまり、外表面）では、空隙率がゼロとなっていることが望ましい。 In the example shown in FIG. 7, the porosity of the case member 107 is the highest at the portion in contact with the internal heat storage material 106, and decreases as the distance from the internal heat storage material 106 increases. In other words, porosity is low from the inside of the case member 107 outwardly. In case member 107, a portion in contact with the first heat medium (i.e., the outer surface), the it is desirable that the porosity is zero.
