して取り出すことができなかった。A heat storage device 1 has a heat storage material 3 in a heat storage tank 2 that changes from liquid to gas when absorbing heat and from gas to liquid when releasing heat, and the density of the condensed liquid is at least higher than the density near the phase transition point of the heat storage material. It is comprised of a heat exchanger 6 for enclosing large heat transfer mediums 2, . In the heat storage state, the heat storage material filling part is made of a heat storage material solution having a temperature equal to or higher than the melting point of the heat storage material,
The space is made up of the saturated vapor pressure of the heat transfer medium at that temperature. ○ When the low temperature heat medium is introduced into the heat exchanger 6, the heat transfer medium in the space exchanges heat in the heat exchanger 6 and is condensed and liquefied. Therefore, the vapor pressure in the space decreases. In order to compensate for this, the heat transfer medium evaporates from the heat storage material filled portion, becomes bubbles 7, rises, and reaches the space. On the other hand, the condensed liquid 8 flows back into the dripping l-heat storage material filling section. The condensed liquid 8 dripped into the heat storage material filling part is the heat storage material 3
Since it has a higher density, it descends into the heat storage material solution. While descending, most of the heat absorbs heat from the heat storage material 3, evaporates, and rises in the form of bubbles. The other part settles to the bottom of the heat storage tank 2, where it gains heat and evaporates again. However, as can be seen from the above explanation, the condensed liquid evaporates mainly in the upper part of the heat storage material filling part, and therefore, although the upper part is vigorously stirred, the stirring becomes gentler as it goes to the lower part. The heat storage material that has lost heat to the shattered and condensed liquid 8 becomes microcrystals, which are suspended and agitated because the solution is stirred by air bubbles. It continues to settle. In this way, the heat storage material filled portion is stirred by the evaporation-condensation cycle of the heat transfer medium 4, and heat exchange is efficiently carried out in the heat exchanger 6. However, in this method, the temperature of the upper part of the heat storage material filling part decreases. This consists of a relatively low-temperature condensate dripping from the top, a relatively low-temperature heat storage material that has lost its latent heat to the condensate, and has become microcrystals, and a heat storage material solution.
, so the temperature is relatively low. When the upper temperature decreases, the temperature of the steam in the space decreases. Therefore, the heat exchange temperature in the heat exchanger 6 decreases, and the temperature increase value of the low-temperature heat medium decreases.As can be seen from the above explanation, In conventional heat exchange, the temperature of the space decreases with the passage of time and the heat exchange efficiency decreases, so the introduced low-temperature heat medium could not be extracted as a high-temperature heat medium with a constant η of 1.1 degrees.

It has a structure in which a heat vibrator is provided between the center part and the upper part of the material filling part.

A heat pipe prevents the temperature from decreasing in the second part by transporting heat to the central part, keeping the temperature constant. As a result, the temperature of the space becomes constant, so that a heating medium of constant temperature can always be obtained. An embodiment of the present invention will be described with reference to FIG. 2. In Fig. 2, the same parts as in Fig. 1 are given the same numbers. In Fig. 2, the heat storage device 1 has a heat storage tank 2, a heat exchanger 5,

ならどのような構造でもよい。Now, when the heat storage device 1 is in a heat storage state, when a low-temperature heat medium flows into the heat exchanger 6, the heat storage material filling part is agitated by the evaporation-condensation cycle of the heat transfer medium 4, as explained in FIG. At the same time, the heat transfer medium exchanges heat in the heat exchanger 6 and radiates heat. At this time, as explained above, the temperature of the upper part of the heat storage material filling section is lowered. In the present invention, a reheat vibrator (including a heat knife on) is disposed between the upper and upper parts of the heat storage material filled part to prevent the temperature from decreasing. That is, as can be seen from the above description, the temperature of the upper part of the heat storage material filling part is relatively high. When the temperature of the second part decreases, the heat in the central part is transmitted to the second part by the heat pipe, thereby preventing the temperature of the upper part from decreasing. For this reason, constant heat exchange can be performed by the heat exchanger 6 without a drop in the temperature of the space, and the low-temperature heat medium can always extract heat as a high-temperature heat medium of approximately constant temperature. The shape of the heat pipe is not limited to the shape shown in FIG. 2, but may have any structure as long as it has excellent heat transfer characteristics, such as a structure with fins.

もさしつかえない。In addition, in the present invention, the heat pipe is inserted above the central part of the heat storage material filling part, but in the lower part of the heat storage tank, the solid heat storage material that has radiated heat has a higher specific gravity than the melted heat storage material, so it settles and accumulates. This is because a constant high temperature cannot be obtained. In FIG. 2, the heat pipe is below the liquid surface, but as can be seen from the above description, it may also protrude above the liquid surface.
なお、上記説明では熱交換器6は気相に設けられた場合
につき説明したが、これに限定されるものでなく、気液

る。In addition, although the above description has been made for the case where the heat exchanger 6 is provided in the gas phase, the present invention is not limited to this, and the same effect can be obtained even if the heat exchanger is provided in both the gas and liquid phases. I can do it.
以上本発明の手段によれば、蓄熱材充填部上部の温度が
放熱時はぼ一定となり、低温熱媒体をほぼ一定温度の高
温熱媒体にすることができる0As described above, according to the means of the present invention, the temperature of the upper part of the heat storage material filled part becomes almost constant during heat radiation, and the low temperature heat medium can be turned into a high temperature heat medium with a substantially constant temperature.
