  The present invention relates to a chemical heat storage reactor, a chemical heat storage system, and a method for manufacturing a chemical heat storage reactor.

  In Patent Document 1, a laminated body is formed by laminating a heat storage material layer, a reaction medium diffusion layer, and a heat exchanging portion, and this laminated body is sandwiched between a pair of end plates from both sides in the laminating direction and restrained. A chemical heat storage reactor of the structure described is described.

  Specifically, in the configuration described in Patent Document 1, by connecting the four corner portions of one end blade and the four corner portions of the other end plate via bolts, a heat storage material layer, a reaction medium diffusion layer, And the binding force which restrains a heat exchange part has arisen.

JP 2014-126293 A

  In the configuration described in Patent Document 1, in order to increase the binding force on the stacked body, it is necessary to enlarge the end plate, which increases the heat capacity. If the heat capacity of the end plate is large, more heat is absorbed by the end plate, so there is room for improvement.

  The object of the present application is to reduce the heat capacities of the chemical heat storage reactor and the chemical heat storage system while suppressing the expansion of the heat storage material layer.

  In the first aspect, a heat storage material layer in which a heat storage material molded body that generates heat by coupling with the reaction medium and stores heat by desorption of the reaction medium is disposed inside the restraint frame, and is stacked on the heat storage material layer and the heat storage material A reaction medium diffusion layer through which the reaction medium supplied to or discharged from the heat storage material layer flows, and heat supply to the heat storage material layer laminated on the heat storage material layer on the opposite side of the reaction medium diffusion layer And a heat exchanger that performs at least one of the heat recovery from the heat storage material layer, and a restraining member that contains the laminate and covers each outer surface of the laminate and restrains the laminate And having.

  In this chemical heat storage reactor, the reaction medium diffusion layer is stacked on the heat storage material layer, and the heat exchange part is stacked on the opposite side of the heat storage material layer from the reaction medium diffusion layer. The heat storage material layer generates heat by being combined with the reaction medium, and the reaction medium is desorbed to store heat.

  The heat storage material layer tends to expand during heat generation (when combined with the reaction medium), but the heat storage body molded body is disposed inside the restraint frame. Moreover, the laminated body is accommodated in the restraining member and can suppress the expansion of the heat storage material layer. The restraining member covers each outer surface of the laminate and restrains the laminate in a state where there are few gaps between the laminate, and the force from the laminate acts in a dispersed manner. There is no need to transiently increase the strength of the restraining member, and the heat capacity of the restraining member is small.

  Thus, a structure with a small heat capacity of the chemical heat storage reactor can be realized by adopting a structure in which the restraining member covers and contacts the outer surface of the laminate and restrains the laminate.

  In a 2nd aspect, the said laminated body is a rectangular parallelepiped shape in a 1st aspect.

  It is possible to restrain a rectangular parallelepiped laminated body so as to be sandwiched in three directions (width direction, depth direction, and height direction) orthogonal to each other by a restraining member.

  According to a third aspect, in the first aspect, the restraining member includes a restraining housing that restrains the stacked body with at least four restraining surfaces including two opposing surfaces, and the restraining surface of the restraining housing includes the restraining surface. A fixing member that covers the non-covered surface and is attached to the restraining housing and fixes the laminated body housed in the restraining housing.

  Therefore, the laminate can be fixed in the restraint housing by inserting the laminate into the restraint housing from the surface without the restraint surface and covering the surface without the restraint surface with the fixing member.

  In a fourth aspect, in the third aspect, the constraining surface constrains the stacked body at both end surfaces in the stacking direction of the stacked body.

  The laminate tends to expand greatly in the stacking direction. Since the constraining surface constrains the stacked body at both end surfaces in the stacking direction, expansion of the stacked body can be effectively suppressed.

  In a 5th aspect, it has a distribution | circulation part which is provided in the said restraint housing and can distribute | circulate gas between the inside and the exterior of the said restraint housing in a 4th aspect.

  With the flow part, the gas as the reaction medium can flow into the inside of the restraining housing or out of the restraining housing.

  In a sixth aspect, in the fifth aspect, the flow section is provided only on a surface facing the reaction medium entrance / exit surface of the laminate.

  In the laminated body, since the flow part is not formed except the surface facing the reaction medium entrance / exit surface, the strength of the restraining housing is high.

  In a seventh aspect, in any one of the second to sixth aspects, a hollow portion is formed in which the restraining housing is partially hollow.

  By forming the hollow portion, it is possible to reduce the weight of the restraining housing. Examples of the hollow portion include a structure in which the inside of the restraining housing is plate-shaped and a through-hole is formed in the plate thickness direction. When the surface of the restraining housing is formed in a fence shape or a lattice shape, a portion between the fence and the lattice is a hollow portion.

  In an eighth aspect, in the seventh aspect, a plurality of the stacked bodies are stacked, and the plurality of stacked bodies are accommodated in the restraining housing.

  The expansion of the heat storage material layer can be more effectively suppressed by accommodating each laminated body in the restraining housing.

  In a ninth aspect, the chemical heat storage reactor according to any one of the first to eighth aspects, the supply of the reaction medium to the reaction medium diffusion layer of the chemical heat storage reactor, and the reaction medium diffusion layer An evaporative condenser that performs at least one of receiving the reaction medium from

  The reaction medium is transferred to the heat storage layer by at least one of supplying the reaction medium to the reaction medium diffusion layer of the chemical heat storage reactor and receiving the reaction medium from the reaction medium diffusion layer by the evaporative condenser. Can do.

  Since the chemical heat storage reactor according to any one of the first to eighth aspects is included, the heat capacity of the chemical heat storage reactor and the chemical heat storage system can be reduced while suppressing the expansion of the heat storage material layer.

  In a tenth aspect, a heat storage material layer that is heated by coupling with the reaction medium and stores heat by desorption of the reaction medium is disposed inside the restraint frame, and the heat storage material is laminated on the heat storage material layer. A reaction medium diffusion layer through which the reaction medium supplied to or discharged from the heat storage material layer flows, and heat supply to the heat storage material layer laminated on the heat storage material layer on the opposite side of the reaction medium diffusion layer And a heat exchanging part that performs at least one of the heat recovery from the heat storage material layer is housed in a restraint housing having at least four restraint surfaces including two opposing faces, and the restraint The laminate is constrained by a surface, a surface of the restraint housing having no restraint surface is covered with a fixing member, the fixing member is attached to the restraint housing, and the laminate housed in the restraint housing is fixed. To do.

  When the laminated body is accommodated in the restraining housing, the restraining surface of the restraining housing faces (preferably contacts) the laminated body, so that deviation of each layer constituting the laminated body can be suppressed.

  In an eleventh aspect, in the tenth aspect, the stacked body is inserted into and accommodated in the direction perpendicular to the stacking direction with respect to the restraining housing.

  Since the laminated body is inserted into the constraining casing in a direction orthogonal to the laminating direction, it is possible to suppress separation of each layer constituting the laminated body in the laminating direction during insertion.

  According to a twelfth aspect, in the ninth or eleventh aspect, the integrally formed plate member is bent to form the restraining casing.

  Since the restraining housing is formed of an integrally formed plate material, the number of parts can be reduced, and the number of steps for assembling the restraining housing to join each surface of the restraining housing into a predetermined shape can be reduced.

  In a thirteenth aspect, in the ninth or eleventh aspect, a plate member molded separately is joined to form the restraining housing.

  Since a restraint housing is formed by joining plate members formed separately, the degree of freedom in shape is high.

  In a fourteenth aspect, in any one of the ninth to thirteenth aspects, the heat storage material molded body is hydrated after the laminated body is accommodated in the restraining casing.

  By inserting the laminated body into the restraining housing, it can be accommodated in the restraining housing in a short time, and the heat storage material molded body is hydrated after housing, so that inadvertent carbonation of the heat storage material molded body can be suppressed.

  In the present invention, the heat capacity of the chemical heat storage reactor and the chemical heat storage system can be reduced while suppressing the expansion of the heat storage material layer.

(Operation of chemical heat storage system)
Next, the operation of the chemical heat storage system 10 will be described.

  In the chemical heat storage system 10, when the heat stored in the chemical heat storage reactor 20 is generated (radiated) from the heat storage material layer 32, as shown in FIG. The 70 communication destinations are switched to the heat utilization object 96. Further, the on-off valve 19 is opened. In this state, an intermediate temperature medium is passed through the heat medium flow path 17 of the evaporation condenser 12 to evaporate the water in the liquid phase part 16B. Then, the generated water vapor moves in the direction of arrow D in the communication path 14 and is supplied into the reaction vessel 22.

  Subsequently, in the reaction vessel 22, the supplied water vapor passes through the reaction medium flow part 26 (see FIGS. 2 and 3). Then, as shown in FIG. 11, the water vapor WG flows through the reaction medium diffusion layer 36. When the water vapor WG passes through the heat storage material constraining layer 34 and comes into contact with the heat storage material layer 32, the heat storage material molded body 40 of the heat storage material layer 32 generates heat (dissipates heat) while causing a hydration reaction. This heat is transported to the heat utilization object 96 by the heat medium flowing in the flow path 54 of the heat flow unit 50.

  On the other hand, when the heat is stored in the heat storage material molded body 40 of the heat storage material layer 32 in the chemical heat storage system 10, as shown in FIG. The tip is switched to the heat source 94. Further, the on-off valve 19 is closed. In this state, the heat medium heated by the heat source 94 flows in the flow path 54 (see FIGS. 10A and 10B) of the heat flow unit 50.

  As shown in FIG. 11, the heat storage material molded body 40 undergoes a dehydration reaction due to the heat of the heat medium flowing through the flow path 54, and this heat is stored in the heat storage material molded body 40.

  Further, the water vapor WG separated from the heat storage material molded body 40 flows from the heat storage material constraining layer 34 into the reaction medium diffusion layer 36. The water vapor WG that has flowed into the reaction medium diffusion layer 36 passes through the reaction medium flow part 26, flows through the communication path 14 in the direction of arrow E, and flows into the evaporation condenser 12 as shown in FIG.

  Then, in the vapor phase portion 16 </ b> A of the evaporation condenser 12, the water vapor is cooled by the refrigerant flowing through the heat medium flow path 17, and the condensed water is stored in the liquid phase portion 16 </ b> B of the container 16.

  It supplements, referring the cycle (an example) of the chemical thermal storage system 10 shown in FIG. 12 about the thermal storage of the thermal storage material molded object 40 demonstrated above, and thermal radiation. FIG. 12 shows the cycle of the chemical heat storage system 10 at the pressure equilibrium point shown in the PT diagram. In this figure, the upper isobaric line shows the dehydration (heat storage) reaction, and the lower isobaric line shows the hydration (exothermic) reaction.

  In this cycle, for example, when the temperature of the heat storage material molded body 40 is stored at 410 ° C., 50 ° C. is the equilibrium temperature for water vapor. And in the chemical heat storage system 10, water vapor | steam is cooled to 50 degrees C or less by heat exchange with the refrigerant | coolant of the heat-medium flow path 17 in the evaporative condenser 12 (refer FIG. 1), and is condensed and becomes water.

  On the other hand, when an intermediate temperature medium is allowed to flow through the heat medium flow path 17, steam having a vapor pressure is generated. For example, in the cycle of FIG. 12, it is understood that when water vapor is generated at 5 ° C., the heat storage material molded body radiates heat at 315 ° C. Thus, in the chemical heat storage system 10 in which the inside is vacuum degassed, heat can be pumped from a low-temperature heat source near 5 ° C. to obtain a high temperature of 315 ° C.

  By the way, when the water vapor W passes through the heat storage material constraining layer 34 and comes into contact with the heat storage material layer 32, the heat storage material molded body 40 generates heat (dissipates heat) while causing a hydration reaction and tries to expand.

  In the present embodiment, as shown in FIGS. 5 and 6, the laminated unit 90 is accommodated in the restraining housing 62. The five surfaces of the restraining housing 62 are in contact with the stacking unit 90, and no useless space (gap) is generated between the stacking unit 90 and the restraining housing 62.

  In particular, the upper restraint surface 62U of the restraining housing 62 is in surface contact with one end surface 90A of the laminated unit 90, and the lower restraint surface 62L is in surface contact with the other end surface 90B of the laminated unit 90. The body 40 is constrained in the stacking direction (vertical direction). Thereby, it is suppressed that each heat storage material molded object 40 of the laminated body 60 expand | swells in a lamination direction (arrow H direction). And also about each member laminated | stacked between each heat storage material layer 32, when the heat storage material molded object 40 expand | swells, it is suppressed that the space | interval of a lamination direction changes. The interval in the stacking direction is the pitch in the stacking direction, and is the distance between the central portion of one member and the central portion of a member disposed adjacent to the one member.

  In particular, in the present embodiment, the upper restraint surface 62U is in contact with the entire surface including the center of the one end surface 90A, and the lower restraint surface 62L is in contact with the entire surface including the center of the other end surface 90B. In this case, the central portion, which is the portion having the strongest expansion force, is restrained, and the expansion can be effectively suppressed.

  Moreover, since the expansion of the heat storage material molded body 40 can be suppressed with high strength as described above, the design of the chemical heat storage reactor 20 so as to effectively cause a reaction with water (reaction medium) in the heat storage material molded body 40. It can be performed.

  Since the upper restraint surface 62U is in contact with the one end surface 90A as a whole, the force from the heat storage material molded body 40 to be expanded as compared with a structure that locally contacts a part of the one end surface 90A. Is distributed. Similarly, the lower restraint surface 62L is in contact with the other end surface 90B in its entirety, and the heat storage material molded body 40 that is to be expanded as compared with a structure that locally “contacts a part of the other end surface 90B. That is, the upper restraint surface 62U and the lower restraint surface 62L restrain the laminated unit 90 (laminated body 60) in a state where stress is dispersed and stress nonuniformity is suppressed.

  As described above, the restraining housing 62 can restrain the stacking unit 90 without creating a useless space between the restraining housing 90 and does not need to increase the strength of the restraining housing 62 excessively. It is possible to reduce the heat capacity of the casing 62. Thus, in the present embodiment, a structure having a small heat capacity is realized as the restraining housing 62. Therefore, the chemical heat storage reactor 20 also has a high efficiency and high performance chemical heat storage reactor because the amount of heat escaping to the restraining housing 62 is reduced. Moreover, weight reduction of the chemical thermal storage reactor 20 can be achieved because the restraint housing 62 is reduced in size.

  In the first embodiment, the five surfaces of the restraining housing 62 are integrally formed. The number of parts is small as compared with a configuration in which each of these surfaces is formed separately and then joined. And the work process at the time of manufacturing the chemical thermal storage reactor 20 also decreases.

  In particular, since the restraining housing 62 includes five surfaces, the laminate unit 90 (laminated body 60) can be strongly restrained using these five surfaces.

  Since the restraint housing 62 has a hollow portion as a space between the fence members 62S, the restraint housing 62 is further reduced in weight as compared with a structure without such a hollow portion.

  Next, the manufacturing method of the chemical heat storage reactor of the first embodiment will be described.

  In the manufacturing method of the first embodiment, the stacked unit 90 is configured by stacking a plurality of stacked bodies 60.

  This laminated unit 90 is inserted into the restraining housing 62. At the time of insertion, as shown in FIG. 7, the insertion is performed from the open surface 62 </ b> K of the restraining housing 62 toward the back side (in the direction of arrow D) in the stacked unit 90. This insertion direction is a direction orthogonal to the stacking direction (arrow H direction and vice versa). Since the laminated unit 90 is not inserted in the laminating direction, the laminated body 60 or each layer constituting the laminated body 60 (the heat storage material layer 32, the heat storage material constraining layer 34, the reaction medium diffusion layer 36, and the heat) The flow part 50 does not inadvertently separate or shift.

  In the middle of inserting the laminated unit 90 into the restraining housing 62, both side surfaces (steam entrance / exit surfaces 90 </ b> D) of the laminating unit 90 are in contact with the steam flow surface 62 </ b> D of the restraining housing 62. For this reason, in the middle of inserting the laminated unit 90 into the restraining housing 62, the laminated body 60 or each layer constituting the laminated body 60 (the heat storage material layer 32, the heat storage material constraining layer 34, the reaction medium diffusion layer 36, and the The heat flow portion 50) does not inadvertently shift in the width direction (arrow W direction and the opposite direction).

  Then, in a state where the laminated unit 90 is accommodated in the restraining housing 62, the fixing member 64 is attached to the restraining housing 62, and the laminated unit 90 is fixed to the restraining member 66.

  The restraint member 66 (lamination unit 90) is accommodated in the reaction vessel 22 while the lamination unit 90 is fixed.

  Since the stacked unit 90 can be accommodated by inserting it into the restraining housing 62 from the open surface 62K, the time required for accommodation is short. Substantially, after the laminated unit 90 (laminated body 60) is accommodated in the restraining housing 62, the heat storage material molded body 40 is hydrated. Since the laminated unit 90 (laminated body 60) can be accommodated in the restraining housing 62 and fixed to the restraining member 66 in a short time, the heat storage material molded body 40 due to hydration when the laminated unit 90 is inserted into the restraining housing 62. Carbonation can be suppressed.

  In 1st embodiment, each surface which comprises the restraint housing 62 is formed separately, and the restraint housing 62 of a predetermined shape can be formed by joining each surface by welding etc. Since each surface of the restraining housing 62 is a separate body, the degree of freedom in shape is high.

<Second embodiment>
Next, a second embodiment will be described with reference to FIGS. 13A and 13B. In addition, about the same element, member, etc. as 1st embodiment, the same code | symbol is attached | subjected and the description is abbreviate | omitted. Further, in each of the following embodiments, the configuration of the laminated unit 90 (laminated body 60) is the same as that of the first embodiment, and hence illustration is omitted. Moreover, since the whole structure of a chemical thermal storage reactor and a chemical thermal storage system is the same as that of 1st embodiment, illustration is abbreviate | omitted.

  In the second embodiment, as shown in FIG. 13B, the constraining housing 262 is formed by bending a single plate member (deployment housing 264) formed in a predetermined shape along a predetermined folding line 266.

  As shown in FIG. 13A, the upper restraining surface 62U of the restraining housing 262 is composed of split surfaces 262D and 262E that are split to the left and right in the width direction. An engaging portion 262K is formed on the abutting side 262F of the dividing surfaces 262D and 262E. By causing the engaging portions 262K to engage with each other, positional displacement of the dividing surfaces 262D and 262E is suppressed.

  The split surfaces 262D and 262E are joined by welding or the like at the abutting side 262F to form the upper restraint surface 62U.

  In the second embodiment, since the unfolded casing 264 formed of one plate material is used in this way, the number of parts constituting the restraining casing 262 can be reduced, and each surface constituting the restraining casing 262 The process of joining (the process of forming the restraining housing 262) is unnecessary.

  And it can be selected by the shape and size of the lamination | stacking unit 90 accommodated in an inside whether a restraint housing | casing is made into the joining structure of several surfaces, or makes it an integral structure (non-joining concept), for example. For this reason, a restraint housing can be manufactured efficiently.

<Third embodiment>
Next, a third embodiment will be described with reference to FIG.

  The restraint housing 362 of the third embodiment has an upper restraint surface 62U, a lower restraint surface 62L, two steam flow surfaces 62D, and a rear restraint surface 62B (see FIG. 7 etc. shown as the first embodiment), all of which are plate-like. It is formed with a member.

  A space 364 is formed in the steam flow surface 62D from the front side so as to cut out the center in the thickness direction of the plate material. The inner thin plate portion 366U and the outer thin plate portion 366S exist on both sides of the space portion 364.

  A through hole 368 is formed in the inner thin plate portion 366U. Steam can flow through the gap 364 and the through-hole 368 to the stacked unit 90 (laminated body 60) accommodated in the restraining housing 362. That is, in the third embodiment, the circulation part 68 is configured by forming the gap part 364 and the through hole 368, and the steam circulation surface 62D has a structure that allows steam to flow.

  Each of the gap portion 364 and the through hole 368 is an example of a hollow portion in which the restraining housing 362 is partially hollow.

  In the third embodiment, since all the five surfaces of the restraining housing 362 are formed in a plate shape, the strength and shape stability of the restraining housing 362 as a whole are high.

  In particular, the circulation portion 68 is formed only on the steam circulation surface 62D that is the surface facing the vapor inlet / outlet surface 90D of the laminate 60, and the circulation portion 68 is not formed on the other surface. For this reason, the strength of the restraining housing 362 is high.

<Fourth embodiment>
Next, a fourth embodiment will be described with reference to FIG. In the fourth embodiment, the same elements and members as those in the first to third embodiments are denoted by the same reference numerals, and detailed description thereof is omitted.

  In the restraint housing 462 of the fourth embodiment, the upper restraint surface 62U, the lower restraint surface 62L, the two steam flow surfaces 62D, and the rear restraint surface 62B are all formed of plate-like members.

  Not only the steam flow surface 62D but also the upper restraint surface 62U and the lower restraint surface 62L are formed with a gap portion 364 cut out from the front in the center in the thickness direction of these plate materials. The portion 366U and the outer thin plate portion 366S are present.

  Furthermore, in the fourth embodiment, the through hole 368 is formed not only in the inner thin plate portion 366U but also in the outer thin plate portion 366S of the steam flow surface 62D. The through-hole 368 of the outer thin plate portion 366S and the through-hole 368 of the inner thin plate portion 366U constitute the flow portion 68.

  Also in the fourth embodiment, since all the five surfaces of the restraining housing 462 are formed in a plate shape, the overall strength and shape stability of the restraining housing 462 are high.

  In particular, since the gap portion 364 is formed in the upper restraint surface 62U and the lower restraint surface 62L, the weight is reduced and the heat capacity is reduced as compared with the structure in which the gap portion 364 is not formed in the upper restraint surface 62U or the lower restraint surface 62L. Can be achieved.

  Also in the fourth embodiment, the circulation portion 68 is formed only on the steam circulation surface 62D that is the surface facing the vapor inlet / outlet surface 90D of the laminate 60, and the circulation portion 68 is formed on the other surface. I can say that it is not. For this reason, the strength of the restraining housing 462 is high.

<Fifth embodiment>
Next, a fifth embodiment will be described with reference to FIG. In the fifth embodiment, elements, members, and the like similar to those in the first to fourth embodiments are denoted by the same reference numerals, and detailed description thereof is omitted.

  In the restraint housing 562 of the fifth embodiment, the upper restraint surface 62U, the lower restraint surface 62L, the two steam flow surfaces 62D, and the rear restraint surface 62B are all formed of plate-like members.

  Not only the steam flow surface 62D but also the upper restraint surface 62U and the lower restraint surface 62L are formed with a gap portion 364 cut out from the front in the center in the thickness direction of these plate materials. The portion 366U and the outer thin plate portion 366S are present. Furthermore, a through hole 368 is formed not only in the inner thin plate portion 366U but also in the outer thin plate portion 366S of the steam flow surface 62D. The through-hole 368 of the outer thin plate portion 366S and the through-hole 368 of the inner thin plate portion 366U constitute the flow portion 68.

  In addition, through holes 368 are formed in the inner thin plate portion 366U and the outer thin plate portion 366S of the upper restricting surface 62U and the lower restricting surface 62L.

  Also in the fifth embodiment, since all the five surfaces of the restraining housing 562 are formed in a plate shape, the strength and shape stability of the restraining housing 562 as a whole are high.

  Since the gap portion 364 is also formed in the upper restraint surface 62U and the lower restraint surface 62L, it is possible to measure weight reduction and low heat capacity.

  In the fifth embodiment, through holes 368 are also formed in the inner thin plate portion 366U and the outer thin plate portion 366S of the upper restricting surface 62U and the lower restricting surface 62L. For this reason, compared with the structure in which the through-hole 368 is not formed in the upper restraint surface 62U and the lower restraint surface 62L, a weight reduction and a low heat capacity can be achieved.

<Sixth embodiment>
Next, a sixth embodiment will be described with reference to FIGS. 17A and 17B.

  In the restraint housing 662 of the sixth embodiment, the upper restraint surface 62U and the lower restraint surface 62L are formed of a lattice-like member. More specifically, the upper restraint surface 62U and the lower restraint surface 62L have a structure in which a plurality of transverse girder members 662Y extending in the width direction intersect with a plurality of stringer members 662T extending in the depth direction. . In the sixth embodiment, the rear restraint surface 62B is also formed by the fence member 62S.

  As described above, in the sixth embodiment, the five surfaces of the restraining housing 662 are formed in a lattice shape or a fence shape. Therefore, it is possible to achieve a reduction in weight and a reduction in heat capacity as compared with a structure in which any surface of the restraining housing is formed in a plate shape. In this respect, it can be said that the space surrounded by the cross beam member 662Y and the vertical beam member 662T and the space between the fence members 62S are also examples of the hollow portion.

<Seventh embodiment>
Next, a seventh embodiment will be described with reference to FIG.

  The restraint housing 762 of the seventh embodiment has a plate-like upper restraint surface 62U and a lower restraint surface 62L, and a fence-like steam flow surface 62D, but does not have a rear restraint surface 62B, and the rear surface is opened. The shape has four surfaces. In other words, the open surface 62K is also formed on the rear side.

  Therefore, in the seventh embodiment, in a state where the laminated unit 90 (laminated body 60) is accommodated in the restraining housing 762, not only the front open surface 62K but also the rear open surface 62K is fixed to the fixing member 64. By attaching (see FIG. 7), the laminated unit 90 (laminated body 60) is fixed.

  In the seventh embodiment, since the open surfaces 62K are formed on both the front side and the rear side, the front and rear of the restraining housing 762 can be used without distinction.

<Eighth embodiment>
Next, an eighth embodiment will be described with reference to FIG.

  The restraint housing 862 of the eighth embodiment has a plate-like upper restraint surface 62U, a lower restraint surface 62L, and a rear restraint surface 62B, but the fence-like steam flow surface 62D is one in the width direction (in the example of FIG. 19). It is formed only on the right side). That is, an open surface 62K is formed on the other side in the width direction (left side in the example in FIG. 19). Since the front side of the restraining housing 862 is also an open surface 62K, the restraining housing 862 has a shape having four surfaces: an upper restraining surface 62U, a lower restraining surface 62L, a rear restraining surface 62B, and one steam flow surface 62D. .

  As described above, even with the restraining housing 862 having the open surface 62K formed on the front side and the one side in the width direction, the laminated unit 90 (laminated body 60) accommodated therein can be restrained. In particular, since the restraining housing 862 has the upper restraining surface 62U and the lower restraining surface 62L, the stacking unit 90 (stacked body 60) can be reliably restrained in the stacking direction.

  In the eighth embodiment, for example, if a fixing member 864 formed in a substantially L shape is used so as to be applied to the open surface 62K on the front side and the one side in the width direction, the stacked unit 90 (stacked) The body 60) can be securely fixed.

<Ninth embodiment>
Next, a ninth embodiment will be described with reference to FIG.

  The restraining housing 962 of the ninth embodiment has a partition surface 964 at an intermediate position in the vertical direction. The partition surface 964 partitions the inside of the restraining housing 962 into two upper and lower spaces (accommodating spaces 966U and 966L).

  In the ninth embodiment, the constraining housing 962 has the upper and lower housing spaces 966U and 966L as described above, and thus the stacked unit 90 (laminated body 60) can be stored in each of the receiving spaces 966U and 966L. .

  The object accommodated in the accommodation spaces 966U and 966L may be a single laminated body 60 (not the laminated unit 90). In particular, in the configuration in which the stacked body 60 is housed alone in the housing spaces 966U and 966L, the expansion of the heat storage material molded body 40 can be more effectively suppressed.

  In addition, one or a plurality of stacked units 90 (stacked body 60) to be stored can be stored and constrained in the storage space of the constraint housing 962, and the time required for assembly can be shortened.

  The number of accommodation spaces is two in the upper and lower directions in the example shown in FIG. 20, but may be three or more.

  In FIG. 20, the partition surface 964 is a single plate material. However, the partition surface 964 may be configured by two upper and lower plate materials, a fence-like member, a lattice-like member, or the like.

<Tenth embodiment>
Next, a tenth embodiment will be described with reference to FIGS.

  In the first to ninth embodiments, the laminated unit 90 (laminated body 60) has a rectangular parallelepiped shape, whereas in the tenth embodiment, the laminated unit 1090 (laminated body 1060) has a cylindrical shape. That is, each laminated body 1060 is formed in a cylindrical shape, and the laminated unit 1090 is also formed in a cylindrical shape by stacking the laminated bodies 1060. Two heat medium flow paths 70A and 70B extend upward from one end face 1090A of the laminated unit 1090.

  And the restraining member 1066 of 10th Embodiment is a shape corresponding to the cylindrical laminated unit 1090 (laminated body 1060).

  Specifically, the restraining member 1066 includes a restraining housing 1062 including a lower restraining surface 1062L, a fence member 1062S, and an upper ring member 1062K. The lower constraining surface 1062L is formed in a disk shape slightly larger in diameter than the laminated unit 1090, and a fence member 1062S is erected from the periphery of the lower constraining surface 1062L with a gap in the circumferential direction. . An annular upper ring member 1062K is fixed to the upper end of the fence member 1062S, and the fence members 1062S are maintained parallel to each other. Between the fence members 1062S is a steam flow surface 1062D through which steam can flow.

  As shown in FIG. 22, one end surface 1090 </ b> A of the laminated unit 1090 is positioned at the same height as the upper end of the restricting housing 1062 in a state where the laminated unit 1090 is accommodated inside the restraining housing 1062. In this way, the fixing member 1064 is attached to the restraining housing 1062 in contact with the one end surface 1090A of the laminated unit 1090 accommodated in the restraining housing 1062. The fixing member 1064 is also an upper restraining surface 1062U in the restraining member 1066.

  In the example shown in FIG. 22, the fixing member 1064 is a plate-like member having a width disposed between the two heat medium flow paths 70A and 70B so as to avoid the heat medium flow paths 70A and 70B. . The fixing member 1064 is attached to the upper ring member 1062 </ b> K, thereby contacting the one end surface 1090 </ b> A of the stacked unit 1090 and restraining the stacked unit 1090. Further, the fence member 1062S surrounds and restrains the periphery of the laminated unit 90 (laminated body 60).

  Both end surfaces of the fixing member 1064 in the longitudinal direction are curved surfaces 1064B that are curved with the same curvature as the outer peripheral portion of the upper ring member 1062K. When the fixing member 1064 is attached to the upper ring member 1062K, it does not protrude from the upper ring member 1064K. Shape.

  In the tenth embodiment, the laminated unit (laminated body) has a cylindrical shape, but other than this, for example, it may have a polygonal column shape, and the shape of the laminated unit (laminated body) is not particularly limited. Therefore, the restraining member only needs to be able to restrain the laminated unit (laminate) corresponding to the shape of the laminated unit (laminate).

  As in the first to ninth embodiments, the rectangular parallelepiped laminated unit 90 (laminated body 60) has three sets of planes parallel to each other. And it is possible to restrain so that the lamination | stacking unit 90 (laminated body 60) may be pinched | interposed by three directions (width direction, depth direction, and height direction) orthogonal to each other by a restraint member.

  In each of the above embodiments, a structure in which a fixing member is attached to the restraining housing is described. For example, each surface of the restraining member (5 or 4 surfaces if a rectangular parallelepiped shape) is formed of a separate member. In the structure to be joined, a member on a specific surface constituting the restraining housing may be regarded as a fixing member. For example, in the first embodiment, the laminated unit 90 (laminated body 60) is accommodated in the restraining housing 62 with the rear restraint surface 62B removed (four faces), and then the fixing member 64 and the rear restraint surface 62B. May be attached to the restraining housing 62. In this case, it can be said that the rear restraint surface 62B substantially acts as a fixing member. The same applies to the other surfaces of the restraining housing 62. The same can be said for the constraining housings of the other embodiments in the structure in which each surface is formed separately.
