空隙５が生じ、両者間の対流による伝熱が阻害される。Conventionally, there has been a problem in the method of heating the heat storage material in a heat storage device using a latent heat type heat storage material. That is, in the conventional heating method, since the latent heat storage material is solid, the area around the heat exchanger is easily melted, but other parts are difficult to melt. This will be explained below using figures. In FIG. 1, a heat storage device A includes a heat storage tank 1, a heat storage material 2, a heating heat exchanger 3 for storing heat in the heat storage material 2, and a heat exchanger 4 for extracting heat from the heat storage material 2.
It is mainly composed of. In this configuration, when the heat storage material 2 is heated by the heating heat exchanger 3 in order to store heat, the heat storage material 2 melts from the periphery of the heating heat exchanger 3. Heat is transferred to the unmelted heat storage material 22 by convection from the melted heat storage material 120, and the heat storage material 2 in the entire heat storage tank 1 is melted. Therefore, it was necessary for convection to occur evenly throughout the tank. However,
With the above configuration, convection did not occur evenly throughout the tank, and it took a long time for the heat storage material 2 to melt. That is,
The lower part of the heat exchanger 3 for υ11 heat and the heat storage material portion on the side of the heat storage tank 1 were difficult to generate convection and were difficult to dissolve. When the heat storage material 2 releases heat and solidifies, small voids are likely to be formed in the heat storage material 2, so when the heat storage material 2 releases heat and solidifies, the voids are are integrated, a gap 5 is created between the melted heat storage material 12 and the unmelted heat storage material 22, and heat transfer by convection between the two is inhibited.

し効率よく蓄熱材を溶解する蓄熱装置の構造に関するも
のである。The presence of undissolved heat storage material in the heat storage tank indicates that when the heat insulation properties are the same, the latent heat utilization rate is lower for the same heat input. Therefore, when heat is extracted from the heat exchanger, the rate at which heat output at a constant temperature, which is a characteristic of latent heat type heat tanks, can be obtained is reduced. In some cases, the temperature of the solution may become abnormally high and the heat storage material itself may deteriorate. The present invention relates to a structure of a heat storage device that solves the above problem and efficiently melts a heat storage material.
本発明は相変化を行なう潜熱形番熱槽において前記蓄熱
装置の下部に底面を覆う加熱源と底面に垂直な加熱源と
を有することを特徴とする。The present invention is characterized in that a latent heat type heat tank that performs a phase change has a heating source that covers the bottom surface and a heating source that is perpendicular to the bottom surface below the heat storage device.

間に空隙が生ずることがないため、槽全体にわたる対流
が生じ蓄熱材を効率よく溶解することができる。With this configuration, the heat storage material can be efficiently melted during heating (heat storage). That is, since the heat storage material is heated over the entire bottom surface of the heat storage tank during heating, the heat storage material in this portion is evenly melted. Since the heat storage material on the top of the trench is melted by a heating source perpendicular to the bottom surface, there is no gap between the melted heat storage material and unmelted heat storage material, so convection flows throughout the tank, making the heat storage material more efficient. Can be dissolved well.

In Fig. 3, the heat storage device ri A is a heat storage tank 1, a heat storage material 2
, a heating heat exchanger 13 and a radiator 4 for extracting the heat from the paralysis. A feature of the present invention is a heating heat exchanger, which is integrally constituted by a heating heat exchanger 131 covering the entire bottom surface 6 and a heating heat exchanger 132 perpendicular to the bottom surface 6. In implementation, the heating heat exchangers 131 and 132 may be separated and independent. Heating J4. In the initial stage, the heat storage material is melted by the J heat exchanger as shown in FIG. 4. That is, in the heating heat exchanger 132IL, the heat storage material 12 in the center of the heat storage tank is melted to penetrate the heat storage +4 tank, and unmelted heat storage material 22 is generated on the upper wall surface of the heat storage tank. This difference in undissolved heat storage material occurs on the upper wall surface of the heat storage tank. This unmelted heat storage material 22 obtains heat from the melted heat storage material 12 at the bottom and the center and melts.

蓄熱材を溶解することができた。In this case, convection occurs throughout the entire tank where the bottom surface is completely molten. 3. Since the molten heat storage tank has a penetrating shape from top to bottom, a void layer as shown in Figure 2 5 does not occur. , it is possible to efficiently melt the heat storage material. Furthermore, when the heating method of the present invention is applied to a direct heat exchange method in which the heat medium, refrigerant, etc. and the heat storage material come into direct contact, no voids are created when the heat storage material solidifies, and the heat storage material in the heat storage tank is efficiently melted. We were able to.

In this case, the dissolution efficiency can be further improved due to the same effect as described above.
