For this reason, it is prevented that the flow volume of the heat medium which flows through the one surface side of the heat storage body 4 and the flow volume of the heat medium which flows through the other surface side of the heat storage body 4 become imbalanced.
- the downstream rectifying member 12 is configured in the same manner as the upstream rectifying member 11.
- the sum total of the cross-sectional areas of the through holes (not shown) of the downstream rectifying member 12 is, for example, 1 ⁇ 2 or less of the cross-sectional area of the flow path cross section (YZ cross section) of the downstream rectifying space 22. According to such a configuration, a predetermined pressure loss can be generated in the flow of the heat medium.
- the heat medium sequentially exchanges heat with the heat storage body 4 from the upstream side of the flow path 5 while the heat medium flows through the flow path 5.
- the heat medium flowing out from the flow path 5 passes through the gap between the adjacent downstream covers 8, the through holes (not shown) of the downstream rectification member, the downstream rectification space 22, and the outlet 3 to store heat. It is discharged to the outside of the container 10.
- the heat storage material 4a In the initial stage of the heat storage process, the heat storage material 4a is in a solid state. Due to the heat exchange between the heat storage material 4a and the heat medium, the temperature of the heat storage material 4a in the solid state rises. Thereby, the heat which a heat carrier has is stored with the form of sensible heat in the solid-state heat storage material 4a. Furthermore, when the temperature of the heat storage material 4a rises to the melting point Tm of the heat storage component of the heat storage material 4a by heat exchange between the heat storage material 4a and the heat medium, the heat storage material 4a changes from a solid state to a gel state. Until the whole heat storage material 4a changes from the solid state to the gel state, the temperature of the heat storage material 4a becomes constant at Tm.
- the heat of the heat medium can be stored in the heat storage material 4a in the form of latent heat.
- the volume of the heat storage material 4a increases, for example, by 10 to 20%.
- the heat storage body 4 is deformed as shown in FIG. 5 or FIG. That is, due to the expansion of the heat storage material 4a, the heat storage body 4 is deformed so that the outer surface of the heat storage body 4 rises toward the non-contact portion 6b.
- the convex part 4p which protrudes toward the non-contact part 6b when the thermal storage material 4a is a gel state is formed in the thermal storage body 4.
- L / T is preferably 0.2 or more. According to this structure, the increase in the volume of the heat storage body 4 caused by the expansion of the heat storage material 4a can be stopped in the space (flow path 5) between the spacer 6 and the outer surface of the heat storage body. Moreover, it can prevent that the flow path 5 is obstruct
- a low-temperature heat medium that has been cooled to a temperature lower than the freezing point Tf of the heat storage component of the heat storage material 4a by heat exchange with air or the like flows from the inlet 2 to the upstream side rectification space 21. Flow into.
- the low-temperature heat medium flows through the inside of the heat storage container 10 as in the heat storage process, and is discharged from the outlet 3 to the outside of the heat storage container 10.
- the heat storage material 4 a is cooled by the heat medium sequentially exchanging heat with the heat storage body 4 from the upstream side of the flow path 5.
- the temperature of the heat storage material 4a in the gel state decreases due to heat exchange between the heat storage material 4a and the heat medium.
- the heat medium is warmed by the sensible heat accompanying the temperature decrease of the heat storage material 4a in the gel state.
- the heat storage material 4a starts to change from a gel state to a solid state.
- the temperature of the heat storage material 4a becomes constant at Tf.
- the heat medium is warmed by the latent heat accompanying this state change. If the whole heat storage material 4a changes to a gel state, the temperature of the heat storage material 4a will fall again.
- the heat medium is also warmed by the sensible heat accompanying the temperature drop of the solid state heat storage material 4a.
- the heated heat medium is discharged from the outlet 3 and then supplied to a heat radiating unit (not shown).
- the heat medium exchanges heat with air or the like in the heat radiating unit.
- the heat stored in the form of latent heat and sensible heat in the heat storage member 4a is supplied to the outside of the heat storage device 1.
- the heat storage body 4 which was the state shown in FIG. 6 in the heat storage process changes into a shape as shown in FIG. That is, the height of the convex portion 4p of the heat storage body 4 is reduced by the contraction of the heat storage material 4a.
- the surface of the solid-state heat storage body 4 has a shape that undulates more gently than the surface of the gel-state heat storage body 4.
- the shape of the heat storage body 4 repeats the shape shown in FIG. 6 and the shape shown in FIG. Since the change of the shape of the heat storage body 4 can be appropriately controlled by the spacer 6, the shape of the heat storage body 4 is stabilized. For this reason, the heat storage device 1 has good reliability in a heat storage / heat radiation cycle.
- the spacer 6 when the heat storage material 4a changes from the gel state to the solid state, the position where the heat storage material 4a contracts cannot be controlled as described above, so the shape of the heat storage body 4 becomes unstable. . For this reason, the reliability of the heat storage device becomes poor.
- the heat medium is not particularly limited as long as it has fluidity.
- the heat medium is, for example, an ethylene glycol aqueous solution or a propylene glycol aqueous solution.
- the heat medium is difficult to freeze below freezing point.
- the heat storage material 4a is not in direct contact with the heat medium, the heat storage material 4a does not have to be insoluble or hardly soluble in the heat medium.
- it is desirable that the heat storage material 4a is insoluble or hardly soluble in the heat medium in order to prevent the heat storage material 4a from eluting into the flow path 5 if the packaging container 4b is damaged.
- Whether or not the heat storage material 4a is hardly soluble in, for example, an ethylene glycol aqueous solution can be determined by, for example, the following solubility evaluation.
- ⁇ Evaluation of solubility of heat storage material> 5.0 g of the heat storage material 4a is added to 70 mL of ethylene glycol heated to a temperature equal to or higher than the melting point of the heat storage component of the heat storage material 4a, and the extraction operation is performed by refluxing ethylene glycol for 3 hours. Thereafter, the heat storage material 4a dissolved in ethylene glycol is extracted into toluene by solvent extraction, the amount of extraction of the heat storage material 4a is quantified by evaporating the toluene, and FT-IR (Fourier transform infrared spectroscopy) is used. Perform composition analysis of the extract.
- FT-IR Fastier transform infrared spectroscopy
- the elution rate of the obtained heat storage component is 0.02 g / m 2 ⁇ h or less, it is determined that the heat storage material 4a is hardly soluble in the ethylene glycol aqueous solution.
- the elution rate can be defined as the amount of heat storage component eluted per hour from the unit surface area of the heat storage material 4a.
- the heat storage material 4a it is comprised by the material containing the paraffin compound and the hydrogenated diene type copolymer which has fixed the paraffin compound so that the heat storage material 4a may show a gel state more than melting
- the heat storage material to which the hydrogenated diene copolymer twice as much as the reference addition amount was added the elution rate was 0.02 g / m 2 ⁇ h. Therefore, the heat storage material corresponding to the latter case is hardly soluble in the aqueous ethylene glycol solution.
- the above embodiment can be modified from various viewpoints.
- the upstream cover 7, the downstream cover 8, the upstream rectifying member 11, or the downstream rectifying member 12 may be omitted as necessary.
- the number of the heat storage bodies 4 arranged inside the heat storage container 10 is not particularly limited, and may be single.
- the stacking direction of the heat storage body 4 and the spacer 6 may be determined in an arbitrary direction.
- the plurality of heat storage bodies 4 and the plurality of spacers 6 may be alternately stacked in the horizontal direction in the heat storage container 10. That is, in the accompanying drawings, the heat storage device 1 may be configured such that the XZ plane is a horizontal plane. According to such a configuration, it is possible to prevent a large load from being applied to a specific heat storage body among the plurality of heat storage bodies 4.

以下、本開示の実施の形態について図面を参照しながら説明する。なお、以下の説明は本発明の一例に関するものであり、本発明はこれらによって限定されるものではない。
次に、蓄熱材4aが固体状態からゲル状態への相変化によって蓄熱する性質を有する場合を例に、蓄熱装置1の動作について説明する。まず、蓄熱過程における蓄熱装置1の動作について説明する。熱源(図示省略)によって、蓄熱材4aの蓄熱成分の融点Tm以上の温度に昇温された熱媒体が流入口2から上流側整流空間21に流入する。上流側整流空間21に流入した熱媒体は、上流側整流部材11の貫通孔11a及び隣り合う上流側カバー7同士の間の隙間を通過して、流路5に流入する。熱媒体は、熱媒体が流路5を流れる間に、流路5の上流側から順次蓄熱体4と熱交換する。流路5から流出した熱媒体は、隣り合う下流側カバー8同士の間の隙間、下流側整流部材の貫通孔(図示省略)、下流側整流空間22、及び流出口3を通過して、蓄熱容器10の外部へ排出される。
