Description

Elastic heat generator

[0001] The present invention relates to an elastic heat generator, and more particularly, to an elastic heat generator capable of heating and cooling a fluid through compression and extension of a shape memory alloy.

[0002]

[0003] Low-temperature heat, typically below 100 degrees Celsius, is frequently emitted during industrial processes, power generation, and transportation. Therefore, the recovery and reuse of these emissions is crucial for energy efficiency.

[0004] In this regard, thermoelectric generators (TEGs) have been developed, but their relatively high cost is a limitation. A novel approach to recovering this energy is using shape memory alloys (SMAs).

[0005] Shape memory alloys (SMAs) are alloys that retain their initial shape after cold forging, returning to their original shape before heating. These materials are lightweight solids that can be applied to conventional actuators, such as hydraulic, pneumatic, and motor-driven systems.

[0006] Due to these material properties, shape memory alloys (SMAs) can be used to construct SMA engines that can recover kinetic energy from thermal energy.

[0007] In this regard, international patent publication WO 2022 / 171843A1 discloses an energy recovery device and an energy recovery method using SMA.

[0008] The above energy recovery device comprises an engine that operates by connecting a plurality of SMA elements to a drive mechanism and a compression device that applies compression mechanical force to the SMA elements.

[0009] At this time, the SMA element is operated by stacking multiple plates vertically and having ports for passing fluid through the multiple plates so that the compression device compresses the fluid.

[0010] However, the energy recovery device as described above has a limitation in that it incurs high manufacturing costs because it requires stacking a large amount of SMA and applying high pressure.

[0011]

[0012] The present invention was created to improve the problems of the conventional elastic heat accumulator as described above, and its purpose is to provide an elastic heat regenerator capable of heating or cooling a fluid using a small amount of shape memory alloy.

[0013] In addition, the purpose is to provide an elastic heat regenerator that can improve heat efficiency by minimizing heat loss of a heated or cooled fluid.

[0014] Additionally, the purpose is to provide an elastic heat generator in which some parts can be replaced when necessary.

[0015] In addition, the purpose is to provide an elastic heat generator that can improve the compression or tensile effect by reducing buckling that may occur during compression and extension of a shape memory alloy.

[0016] In addition, the purpose is to provide an elastic heat storage cooling / heating system that can be used for cooling or heating using an elastic heat storage accumulator.

[0017] In addition, the purpose is to provide an elastic heat capacity heating and cooling system that can directly heat or cool coolant without using a separate refrigerant.

[0018]

[0019] In order to achieve the above-described purpose, the elastic heat generator according to the present invention may include: a plate formed of a shape memory alloy material and having a through hole formed therein; a rod penetrating the plate; and a housing formed of a resin material and accommodating the plate therein.

[0020] At this time, the plates are stacked in multiple numbers within the housing, and the load can pass through the through holes of the multiple stacked plates.

[0021] At this time, fluid can flow between the plate and the load.

[0022] Additionally, a fluid can flow between the plate and the housing.

[0023] Meanwhile, the plate may be formed with one or more fluid passage slits through which fluid can flow.

[0024] Meanwhile, the fluid passage slit may be formed along the circumferential direction with the load as the center.

[0025] In order to achieve the above-mentioned purpose, an elastic heat generator according to another embodiment of the present invention comprises: a housing formed of a resin material and having a through hole formed therein; and a tube accommodated in the through hole and formed of a shape memory alloy material; wherein the diameter of the through hole may be larger than the diameter of the tube.

[0026] At this time, fluid can flow between the tube and the inner surface of the housing.

[0027] Meanwhile, an elastic heat generator according to another embodiment of the present invention may further include a holder coupled to the axial end of the housing and the tube.

[0028] At this time, the holder may include a holder body in the shape of a disk; a tube holder portion that protrudes along the circumference of the holder body, has the tube coupled therein, and is inserted into the through hole; and a housing holder portion that is formed on the radially outer side of the tube holder portion and has the housing coupled thereto.

[0029] At this time, a fluid passage hole through which the fluid can pass may be formed in the tube holder portion.

[0030] Meanwhile, the housing may be formed in a cylindrical or cylindrical shape, and one or more through holes may be formed along the axial direction.

[0031] Meanwhile, an elastic heat generator according to another embodiment of the present invention may further include a clamp in which the housing and the tube are joined to one axial end surface.

[0032] At this time, the clamp may include a cylindrical clamp body; a tube holder portion formed to protrude along a circumferential direction from an axial end surface of the clamp body and to which the tube is coupled; and a housing holder portion formed on a radially outer side of the tube holder portion and to which the housing is coupled.

[0033] In addition, the clamp may further include a clamp hole formed on the outer surface of the clamp body and communicating with the inner space of the housing.

[0034] In order to achieve the above-described purpose, the elastic heat cooling and heating system according to the present invention may include a first regenerator in which cooling water flows and heats the cooling water when compressed and cools the cooling water when expanded; a second regenerator that expands when the first regenerator is compressed and compresses when the first regenerator is expanded; a first heat exchanger through which cooling water cooled in the first regenerator and the second regenerator passes; and a second heat exchanger through which cooling water heated in the first regenerator and the second regenerator passes.

[0035] At this time, the elastic heat cooling and heating system according to the present invention may further include a first switching valve that causes the cooling water to flow to the first heat exchanger while the first regenerator or the second regenerator cools the cooling water, and causes the cooling water to flow to the second heat exchanger while the first regenerator or the second regenerator heats the cooling water.

[0036] In addition, the elastic heat cooling and heating system according to the present invention may further include a second switching valve that causes the cooling water that has passed through the first heat exchanger to flow to the first regenerator while the first regenerator cools the cooling water, and causes the cooling water that has passed through the first heat exchanger to flow to the second regenerator while the second regenerator cools the cooling water.

[0037] Meanwhile, the second switching valve can cause the cooling water that has passed through the second heat exchanger to flow to the first regenerator while the first regenerator is heating the cooling water, and can cause the cooling water that has passed through the second heat exchanger to flow to the second regenerator while the second regenerator is heating the cooling water.

[0038] Meanwhile, the elastic heat cooling and heating system according to the present invention may further include a hydraulic cylinder coupled to the first regenerator and the second regenerator to compress or extend the first regenerator and the second regenerator.

[0039] At this time, the hydraulic cylinder can compress the second regenerator when extending the first regenerator, and can compress the first regenerator when extending the second regenerator.

[0040] Meanwhile, the elastic heat cooling and heating system according to the present invention may further include a fixing member coupled to one side of the first regenerator and the second regenerator to support the first regenerator and the second regenerator.

[0041] Meanwhile, the elastic heat cooling and heating system according to the present invention may further include: a first regenerator pipe communicating with one side of the first regenerator; a second regenerator pipe communicating with one side of the second regenerator; a third regenerator pipe communicating with the other side of the first regenerator; a fourth regenerator pipe communicating with the other side of the second regenerator; a first connection pipe communicating with one side of the first heat exchanger; a second connection pipe communicating with one side of the second heat exchanger; a third connection pipe communicating with the other side of the first heat exchanger; and a fourth connection pipe communicating with the other side of the second heat exchanger.

[0042] At this time, the first switching valve can connect the first regenerator pipe to one of the first connecting pipe and the second connecting pipe, and can connect the second regenerator pipe to the other of the first connecting pipe and the second connecting pipe.

[0043] Additionally, the second switching valve may connect the third regenerator pipe to one of the third connecting pipe and the fourth connecting pipe, and may connect the fourth regenerator pipe to the other one of the third connecting pipe and the fourth connecting pipe.

[0044] At this time, the first switching valve can switch the connection of the pipe when the inlet cylinder switches the compression direction.

[0045] Additionally, the second switching valve can switch the connection of the pipe in conjunction with the first switching valve.

[0046]

[0047] As described above, the elastic heat generator according to the present invention has the effect of reducing the amount of shape memory alloy used by forming a plurality of plate shapes or cylindrical shapes using shape memory alloy.

[0048] Additionally, the perimeter of the shape memory alloy can be wrapped with a resin material housing to minimize heat loss of the heated or cooled fluid.

[0049] In addition, it has the effect of allowing replacement of some parts when necessary by configuring a plurality of units made of shape memory alloy and housing to be connected by a holder.

[0050] Additionally, in the case of a plate shape, there is an effect of reducing buckling by arranging the load to penetrate the center.

[0051] Alternatively, there is an effect that can reduce buckling by forming the shape memory alloy itself into a cylindrical shape and surrounding it with a cylindrical housing.

[0052] In addition, it has the effect of being able to be used for cooling or heating by having a pair of elastic heat accumulators to repeat compression and extension and operating a switching valve in conjunction with them.

[0053] Additionally, there is an effect that allows the coolant to flow inside the elastic heat accumulator to directly heat or cool the coolant.

[0079]

[0080] FIG. 1 is a perspective view illustrating an elastic heat regenerator according to an embodiment of the present invention, FIG. 2 is a perspective view illustrating a case where a plate is square in an elastic heat regenerator according to an embodiment of the present invention, FIG. 3 is a cross-sectional view illustrating an elastic heat regenerator according to an embodiment of the present invention, and FIG. 4 is a front view illustrating a state in which a fluid passage hole is formed in a plate in an elastic heat regenerator according to an embodiment of the present invention.

[0081] An elastic heat generator (100) according to one embodiment of the present invention will be described with reference to FIGS. 1 to 4 as follows.

[0082] An elastic heat generator (100) according to one embodiment of the present invention includes a plate (110), a rod (120), a housing (130), and a clamp (150).

[0083] The plate (110) is formed using a shape-memory alloy (SMA). A shape-memory alloy (SMA) is an alloy that remembers its initial shape through cold forging, and has the property of returning to its original shape before deformation by heating even when deformed into a different shape.

[0084] Meanwhile, the plate (110) according to the present embodiment may be formed in a circular shape. At this time, a through hole (110a) may be formed at the radial center of the plate (110). For example, the through hole (110a) may be a circular hole.

[0085] In contrast, as shown in FIG. 2, the plate (110) may be formed in a square plate shape.

[0086] At this time, the plates (110) can be arranged in a stacked form in multiple pieces, and the through holes (110a) of each plate (110) are aligned coaxially so that the rods (120) described later can pass through them.

[0087] Meanwhile, as illustrated in FIG. 4, a fluid passage slit (112) may be formed in the plate (110). The fluid passage slit (112) may be formed along the circumferential direction with the through hole (110a) as the center. That is, the fluid passage slit (112) may be formed along the circumferential direction with the rod (120) as the center.

[0088] Through this, the fluid can flow inside the multiple stacked plates (110), and the area of ​​contact between the fluid and the plates (110) can be expanded, so that heat transfer efficiency can be improved.

[0089] A plurality of stacked plates (110) can be pressed against each other and compressed when pressed by a clamp (150) to be described later, thereby dissipating heat to the surroundings. At this time, the fluid flowing around the plates can be heated.

[0090] Additionally, when heat is applied while compressed, it can absorb surrounding heat while returning to its original shape (extending). This can cool the fluid flowing around it.

[0091] Meanwhile, when compression occurs in the axial direction while multiple plates (110) are stacked, buckling may occur in a direction crossing the axial direction. In this case, the amount of deformation is reduced, resulting in a decrease in the amount of heat dissipation and absorption.

[0092] To solve this, the present invention further includes a rod (120) penetrating multiple stacked plates (110).

[0093] The load (120) can be arranged to pass through the through hole (110a) of a plurality of stacked plates (110).

[0094] Through this, the center of the plate (110) can be supported and buckling can be reduced.

[0095] The rod (120) can be formed in a cylindrical shape. This can prevent the plate (110) from being damaged by friction with the rod (120) during the process of being compressed or extended.

[0096] Meanwhile, a space may be formed between the rod (120) and the plate (110). That is, the diameter of the through hole (110a) may be formed to be larger than the diameter of the rod (120). Through this, a fluid may flow between the rod (120) and the plate (110). Accordingly, the contact area between the plate (110) and the fluid may be increased, and heat transfer efficiency may be increased.

[0097] The housing (130) can accommodate a plate (110) therein. Specifically, the housing (130) can be formed in a cylindrical shape so as to accommodate the plate (110) therein. At this time, the inner diameter of the housing (130) can be formed to be larger than the outer diameter of the plate (110). Therefore, a fluid flow space (111) can be formed between the inner surface of the housing (130) and the plate (110). A fluid introduced into the housing (130) can flow in the fluid flow space (111). The fluid flowing in the fluid flow space (111) can be heated or cooled by the plate (110).

[0098] Meanwhile, depending on the embodiment, the housing (130) may be formed in the shape of a corrugated tube. When the housing (130) is in the shape of a corrugated tube, there is an advantage in that the compression and restoration of the housing (130) becomes easier when the plate (110) is compressed and restored.

[0099] The housing (130) may be formed of a resin material. For example, the resin material may be poly(methyl methacrylate) (PMMA) or a silicone-based material. PMMA or a silicone-based material has a low heat transfer rate, and thus can prevent heat generated from the internal plate (110) from being released to the outside of the housing (130). Therefore, the present invention can minimize heat loss by the housing (130). In addition, the housing (130) has elasticity, so that when the plate (110) is compressed, it can be compressed together, and when the plate (110) is restored, it can be restored together.

[0100] The clamp (150) can be coupled to both axial ends of the plate (110) and the housing (130). The clamp (150) can block both ends of the plate (110) and the housing (130).

[0101] Although not shown, the clamp (150) can be coupled to an actuator to receive an external force. When the actuator presses the clamp (150), the clamp (150) can press the plate (110) to compress the plate (110).

[0102] For example, the clamp (150) may be formed in a cylindrical shape. At this time, a structure that can be coupled with the housing (130) and the rod (120) may be formed at one axial end of the clamp (150). That is, a groove that accommodates the longitudinal end of the housing (130) and a groove that accommodates the longitudinal end of the rod (120) may be formed at one axial end of the clamp (150).

[0103] Additionally, a flow path through which a fluid can flow may be formed inside the clamp (150). At this time, the flow path may be formed from one axial end to which the housing (130) is coupled, formed along the axial direction, and then bent to form to the outer surface of the clamp (150).

[0104] That is, a clamp hole (151) is formed on the outer surface of the clamp (150) so that fluid can flow. The clamp hole (151) is connected to a pipe so that fluid can flow. Through this, external fluid can flow into the clamp (150) on one side, pass through the housing (130), and then be discharged to the clamp (150) on the other side. In this process, the fluid passing through the regenerator (100) can receive heat from the plate (110) or lose heat to the plate (110).

[0105]

[0106] Meanwhile, FIG. 5 is a perspective view illustrating an elastic heat regenerator according to another embodiment of the present invention, FIG. 6 is a perspective view illustrating a state in which a plurality of tubes are provided in an elastic heat regenerator according to another embodiment of the present invention, FIG. 7 is a perspective view illustrating a state in which a holder is coupled in an elastic heat regenerator according to another embodiment of the present invention, FIG. 8 is a cross-sectional view illustrating an elastic heat regenerator according to another embodiment of the present invention, FIG. 9 is a cross-sectional view illustrating FIG. 7, FIG. 10 is a front view illustrating a tube holder portion in an elastic heat regenerator according to another embodiment of the present invention, FIG. 12 is a perspective view illustrating a clamp in an elastic heat regenerator according to another embodiment of the present invention, and FIG. 13 is a cross-sectional view illustrating FIG. 12.

[0107] Referring to FIGS. 5 to 13, an elastic heat generator (1100) according to another embodiment of the present invention will be described as follows.

[0108] Meanwhile, in order to avoid redundant explanation, except for the contents specifically described in this embodiment, the elastic heat regenerator (100) of one embodiment of the present invention has the same structure and effect, and thus can be used.

[0109] An elastic heat generator (1100) according to another embodiment of the present invention includes a tube (1110), a housing (1130), a holder (1140), and a clamp (1150).

[0110] The tube (1110) is formed using a shape-memory alloy (SMA).

[0111] The tube (1110) can be formed in a cylindrical or cylindrical shape.

[0112] The tube (1110) can be accommodated in a through hole (1111) formed in the housing (1130). At this time, the diameter of the tube (1110) can be smaller than the diameter of the through hole (1111). Therefore, a space can be formed between the outer surface of the tube (1110) and the inner surface of the housing (1130). Through this, a fluid can flow between the outer surface of the tube (1110) and the inner surface of the housing (1130). Therefore, the contact area between the tube (1110) and the fluid can be increased, and heat transfer efficiency can be increased.

[0113] A single tube (1110) can be combined with a single housing (1130) to form a single tube unit. A plurality of the tube units can be arranged along the axial direction, and a holder (1140) can be arranged between the tube units. In addition, a clamp (1150) can be arranged at both ends where the plurality of tube units are connected.

[0114] Accordingly, both axial ends of one tube (1110) can be coupled to a holder (1140) or a clamp (1150). Through this, when an external force is applied, the tube can be compressed in the axial direction by coming into contact with the holder (1140) or the clamp (1150).

[0115] The tube (1110) can be compressed and pressed by the holder (1140) or the clamp (150), thereby dissipating heat to the surroundings. At this time, the fluid flowing around the tube can be heated.

[0116] Additionally, when heat is introduced while in a compressed state, the tube (1110) can absorb heat from the surroundings while returning to its original shape (by stretching). Accordingly, the fluid flowing around it can be cooled.

[0117] The housing (1130) can accommodate a tube (1110) therein. Specifically, the housing (1130) can be formed in a cylindrical or cylindrical shape so as to accommodate the tube (1110) therein. For example, the housing (1130) can have a through hole (1111) formed axially at the radial center. As another example, the housing (1130) can also have a plurality of through holes (1111) formed axially. Through this, the number of tubes (1110) used can be changed, and the amount of heating or cooling can be controlled by arranging a plurality of tubes (1110) within a limited space.

[0118] At this time, the inner diameter of the housing (1130) may be formed to be larger than the outer diameter of the tube (1110). That is, the diameter of the through hole (1111) may be larger than the diameter of the tube (1110). Therefore, the fluid introduced into the housing (1130) may flow between the inner surface of the housing (1130) and the outer surface of the tube (1110). The fluid flowing through the through hole (1111) may be heated or cooled by the tube (1110).

[0119] The housing (1130) may be formed of a resin material. For example, the resin material may be poly(methyl methacrylate) (PMMA) or a silicone-based material.

[0120] The holder (1140) can be coupled to the axial ends of the housing (1130) and the tube (1110). At this time, the housing (1130) and the tube (1110) can be coupled to each of the two sides of the holder (1140). That is, the holder (1140) can be arranged between a plurality of housings (1130) and tubes (1110) arranged along the axial direction. Through this, a tube unit composed of a tube (1110) and a housing (1130) can be connected through the holder (1140), and when a part of the tube unit is damaged, only the corresponding tube unit can be replaced.

[0121] In addition, since the holder (1140) aligns and maintains the position of the tube (1110), buckling can be prevented during the compression process of the tube (1110). This can improve heating and cooling efficiency.

[0122] The holder (1140) includes a holder body (1141), a tube receiving groove (1142), a tube holder portion (1143), and a housing holder portion (1144).

[0123] For example, the holder body (1141) may be formed in a circular shape. At this time, a tube receiving groove (1142), a tube holder portion (1143), and a housing holder portion (1144) may be formed on each of both sides of the holder body (1141).

[0124] The tube receiving groove (1142) is formed at the radial center of both sides of the holder body (1141), and the axial end of the tube (1110) can be brought into contact with it.

[0125] The tube holder portion (1143) is formed to protrude from both sides of the holder body (1141), and a tube receiving groove (1142) is formed inside. At this time, the inner diameter of the tube holder portion (1143) may be formed to correspond to the outer diameter of the tube (1110). For example, the inner diameter of the tube holder portion (1143) may be the same as the outer diameter of the tube (1110). Accordingly, the tube holder portion (1143) may compress the tube (1110) or fix the tube (1110) when the tube (1110) is restored.

[0126] The housing holder portion (1144) is formed on both sides of the holder body (1141), and the housing (1130) can be coupled thereto. That is, the housing holder portion (1144) may be a groove formed along the circumferential direction on both sides of the holder body (1141). At this time, the housing holder portion (1144) may be formed on the radially outer side of the tube holder portion (1143). Therefore, the housing holder portion (1144) may compress the tube (1110) or fix the housing (1130) when the tube (1110) is restored.

[0127] A fluid passage hole (1143a) may be formed in the tube holder portion (1143). Through this, the internal space of the housing (1130) coupled to both sides of the holder (1140) may be connected.

[0128] The clamp (1150) can be coupled to both axial ends of the tube (1110) and the housing (1130). The clamp (1150) can block both ends of the tube (1110) and the housing (1130).

[0129] One axial side of the clamp (1150) can be coupled with a tube (1110) and a housing (1130), and the other axial side of the clamp (1150) can be coupled with an actuator (not shown).

[0130] Although not shown, the clamp (1150) may be coupled to an actuator to receive an external force. When the actuator presses the clamp (1150), the clamp (1150) may pressurize the tube (1110) to compress the tube (1110).

[0131] The clamp (1150) includes a clamp body (1151), a tube receiving groove (1152), a tube holder portion (1153), a housing holder portion (1154), and a clamp hole (1155).

[0132] For example, the clamp body (1151) may be formed in a cylindrical shape. At this time, a tube receiving groove (1152), a tube holder portion (1153), and a housing holder portion (1154) may be formed on one axial end of the clamp body (1151).

[0133] The tube receiving groove (1152) is formed at the radial center of one axial end of the clamp body (1151), and the axial end of the tube (1110) can be brought into contact with it.

[0134] The tube holder portion (1153) is formed to protrude from one axial end of the clamp body (1151), and a tube receiving groove (1152) is formed inside. At this time, the inner diameter of the tube holder portion (1153) may be formed to correspond to the outer diameter of the tube (1110). For example, the inner diameter of the tube holder portion (1153) may be the same as the outer diameter of the tube (1110). Accordingly, the tube holder portion (1153) may compress the tube (1110) or fix the tube (1110) when the tube (1110) is restored.

[0135] The housing holder portion (1154) is formed on one axial end of the clamp body (1151), and the housing (1130) can be coupled thereto. That is, the housing holder portion (1154) may be a groove formed along the circumferential direction on one axial end surface of the clamp body (1151). At this time, the housing holder portion (1154) may be formed on the radially outer side of the tube holder portion (1153). Therefore, the housing holder portion (1154) may compress the tube (1110) or fix the housing (1130) when the tube (1110) is restored.

[0136] Additionally, a flow path through which a fluid can flow may be formed inside the clamp (1150). At this time, the flow path may be formed from one axial end to which the housing (1130) is coupled, formed along the axial direction, and then bent to form the outer surface of the clamp (1150).

[0137] Specifically, one side of the above-described flow path may be connected to a fluid passage hole (1153a). The fluid passage hole (1153a) may be formed in the tube holder portion (1153). Through this, the fluid passing through the flow path inside the clamp (1150) may flow into the housing (1130), and the fluid discharged from the housing (1130) may flow into the clamp (1150).

[0138] Additionally, the other side of the above-described flow path may be connected to a clamp hole (1155). The clamp hole (1155) may be formed on the outer surface of the clamp (150). The clamp hole (1155) is connected to a pipe so that a fluid may flow therethrough. Through this, an external fluid may flow into the clamp (1150) on one side, pass through the housing (1130), and then be discharged to the clamp (1150) on the other side. In this process, the fluid passing through the regenerator (1100) may receive heat from the tube (1110) or lose heat to the tube (1110).

[0139]

[0140] Meanwhile, FIGS. 14 and 15 illustrate schematic diagrams illustrating an elastic heat cooling and heating system according to one embodiment of the present invention.

[0141] Referring to FIGS. 14 and 15, the elastic heat cooling and heating system of the present invention is described as follows.

[0142] The elastic heat cooling and heating system of the present invention includes a first regenerator (10), a second regenerator (20), a fixing member (30), a hydraulic cylinder (40), a first heat exchanger (50), a second heat exchanger (60), a first switching valve (70), a second switching valve (80), and a piping member.

[0143] The first regenerator (10) and the second regenerator (20) may be elastic heat regenerators (100, 1100) of the present invention. Accordingly, the first regenerator (10) and the second regenerator (20) may have a fluid flowing therein, heat the fluid when compressed, and cool the fluid when extended (restored). At this time, the fluid may be a coolant.

[0144] Therefore, according to the present invention, there is an effect of directly heating or cooling the coolant by allowing the coolant to flow inside the first regenerator (10) and the second regenerator (20).

[0145] At this time, in the present invention, the first regenerator (10) and the second regenerator (20) can be compressed and expanded in conjunction with each other. Specifically, when the first regenerator (10) is compressed, the second regenerator (20) can be expanded, and when the first regenerator (10) is expanded, the second regenerator (20) can be compressed.

[0146] To this end, one longitudinal side of the first regenerator (10) and the second regenerator (20) is fixed by being joined to a fixing member (30), and the other longitudinal side of the first regenerator (10) and the other longitudinal side of the second regenerator (20) can each be joined to a hydraulic cylinder (40).

[0147] At this time, the hydraulic cylinder (40) may be a pair of hydraulic cylinders each connected to the first regenerator (10) and the second regenerator (20) in a cylindrical manner, or each hydraulic cylinder may be electronically controlled to operate individually.

[0148] Accordingly, the first regenerator (10) can be compressed and the second regenerator (20) can be extended at the same time as the hydraulic cylinder (40) is operated, and the second regenerator (20) can be compressed and the first regenerator (10) can be extended at the same time.

[0149] At this time, the fixed part (30) can support one side of the first regenerator (10) and the second regenerator (20) in the longitudinal direction. For example, the fixed part (30) can be composed of a wall or a metal plate, and can support one side of the first regenerator (10) and the second regenerator (20) even when pressurized by a hydraulic cylinder (40).

[0150] The hydraulic cylinder (40) can be operated by hydraulic pressure applied when the first regenerator (10) or the second regenerator (20) is restored. Meanwhile, although not shown, the hydraulic cylinder (40) can additionally receive hydraulic pressure from a separate power source to apply pressure required for compression of the first regenerator (10) or the second regenerator (20).

[0151] The hydraulic cylinder (40) can be applied to various known hydraulic cylinder types, and a detailed description of the detailed structure is omitted.

[0152] The first heat exchanger (50) and the second heat exchanger (60) can exchange heat of the cooling water flowing in from the first regenerator (10) or the second regenerator (20). That is, the first heat exchanger (50) and the second heat exchanger (60) can cool or heat an object or cool or heat a room using the cooling water flowing in from the first regenerator (10) or the second regenerator (20).

[0153] Specifically, the first heat exchanger (50) according to one embodiment of the present invention can receive cooling water cooled from the first regenerator (10) or the second regenerator (20). For example, the first heat exchanger (50) can be a water tank. The water tank can accommodate a heating element therein. In addition, cooling water cooled from the first regenerator (10) or the second regenerator (20) can be received into the water tank to cool the heating element.

[0154] Additionally, the second heat exchanger (60) according to one embodiment of the present invention can pass cooling water heated in the first regenerator (10) or the second regenerator. At this time, the second heat exchanger (60) can cool the heated cooling water through heat exchange with the outside. At this time, if the second heat exchanger (60) is equipped with a fan, it can be used as a heater. This can increase energy efficiency.

[0155] Meanwhile, the first regenerator (10), the second regenerator (20), the first heat exchanger (50), and the second heat exchanger (60) may each be provided with a piping section.

[0156] Specifically, a first regenerator pipe (91) may be coupled to one longitudinal side of the first regenerator (10), and a third regenerator pipe (93) may be coupled to the other longitudinal side of the first regenerator (10). Accordingly, one longitudinal side of the first regenerator (10) may be connected to the first regenerator pipe (91), and the other longitudinal side of the first regenerator (10) may be connected to the third regenerator pipe (93).

[0157] In addition, a second regenerator pipe (92) may be coupled to one longitudinal side of the second regenerator (20), and a fourth regenerator pipe (94) may be coupled to the other longitudinal side of the second regenerator (20). Accordingly, one longitudinal side of the second regenerator (20) may be connected to the second regenerator pipe (92), and the other longitudinal side of the second regenerator (20) may be connected to the fourth regenerator pipe (94).

[0158] In addition, a first connecting pipe (95) may be coupled to one longitudinal side of the first heat exchanger (50), and a third connecting pipe (97) may be coupled to the other longitudinal side of the first heat exchanger (50). Accordingly, one longitudinal side of the first heat exchanger (50) may be connected to the first connecting pipe (95), and the other longitudinal side of the first heat exchanger (50) may be connected to the third connecting pipe (97).

[0159] In addition, a second connecting pipe (96) may be coupled to one longitudinal side of the second heat exchanger (60), and a fourth connecting pipe (98) may be coupled to the other longitudinal side of the second heat exchanger (60). Accordingly, one longitudinal side of the second heat exchanger (60) may be connected to the second connecting pipe (96), and the other longitudinal side of the second heat exchanger (60) may be connected to the fourth connecting pipe (98).

[0160] Meanwhile, although not shown, an elastic heat cooling and heating system according to one embodiment of the present invention may be equipped with a pump that provides a cooling water flow force. The pump may be positioned on a pipe section. For example, the pump may be positioned on at least one of the first connecting pipe (95), the second connecting pipe (96), the third connecting pipe (97), and the fourth connecting pipe (98).

[0161] For example, in one embodiment of the present invention, the pump can provide a flow force so that the cooling water flows into the first regenerator (10) through the third regenerator pipe (93) and the cooling water discharged from the first regenerator (10) flows into the first regenerator pipe (91).

[0162] Additionally, the pump can provide a flow force so that the cooling water flows into the second regenerator (20) through the fourth regenerator pipe (94) and the cooling water discharged from the second regenerator (20) flows into the second regenerator pipe (92).

[0163] The first switching valve (70) can connect the first regenerator pipe (91) to one of the first connecting pipe (95) and the second connecting pipe (96), and can connect the second regenerator pipe (92) to the other of the first connecting pipe (95) and the second connecting pipe (96).

[0164] The first switching valve (70) and the second switching valve (80) can switch the connection of the pipe when the hydraulic cylinder (40) switches the compression direction. That is, the first switching valve (70) and the second switching valve (80) can switch the connection of the pipe when the regenerator that the hydraulic cylinder (40) compresses changes.

[0165] At this time, the first switching valve (70) can cause the cooling water to flow to the first heat exchanger (50) while the first regenerator (10) or the second regenerator (20) is cooling the cooling water, and can cause the cooling water to flow to the second heat exchanger (60) while the first regenerator (10) or the second regenerator (20) is heating the cooling water.

[0166] Specifically, the first switching valve (70) can connect the first regenerator pipe (91) to the first connecting pipe (95) while the first regenerator (10) cools the coolant, and can connect the second regenerator pipe (92) to the first connecting pipe (95) while the second regenerator (20) cools the coolant. In addition, the first switching valve (70) can connect the first regenerator pipe (91) to the second connecting pipe (96) while the first regenerator (10) heats the coolant, and can connect the second regenerator pipe (92) to the second connecting pipe (96) while the second regenerator (20) heats the coolant.

[0167] The second switching valve (80) can connect the third regenerator pipe (93) to one of the third connection pipe (97) and the fourth connection pipe (98), and can connect the fourth regenerator pipe (94) to the other of the third connection pipe (97) and the fourth connection pipe (98).

[0168] The second switching valve (80) can switch the connection of the pipe in conjunction with the first switching valve (70). That is, the second switching valve (80) can switch the connection of the pipe when the hydraulic cylinder (40) switches the compression direction.

[0169] At this time, the second switching valve (80) can cause the cooling water that has passed through the first heat exchanger (50) to flow to the first regenerator (10) while the first regenerator (10) is cooling the cooling water, and can cause the cooling water that has passed through the first heat exchanger (50) to flow to the second regenerator (20) while the second regenerator (20) is cooling the cooling water.

[0170] In addition, the second switching valve (80) can cause the cooling water that has passed through the second heat exchanger (60) to flow to the first regenerator (10) while the first regenerator (10) is heating the cooling water, and can cause the cooling water that has passed through the second heat exchanger (60) to flow to the second regenerator (20) while the second regenerator (20) is heating the cooling water.

[0171] Specifically, the second switching valve (80) can connect the third regenerator pipe (93) to the third connection pipe (97) while the first regenerator (10) cools the coolant, and can connect the third regenerator pipe (93) to the fourth connection pipe (98) while the second regenerator (20) cools the coolant. In addition, the second switching valve (80) can connect the fourth regenerator pipe (94) to the third connection pipe (97) while the first regenerator (10) heats the coolant, and can connect the fourth regenerator pipe (94) to the fourth connection pipe (98) while the second regenerator (20) heats the coolant.

[0172] Therefore, according to the present invention, a pair of regenerators (10, 20) are provided to repeat compression and expansion, and a switching valve (70, 80) is operated in conjunction with the regenerators, so that it can be used for cooling or heating.

[0173] In an elastic heat capacity heating and cooling system of this configuration, the flow of coolant is described as follows.

[0174] When the hydraulic cylinder (40) is operated, the first regenerator (10) and the second regenerator (20) are compressed alternately.

[0175] Accordingly, when the first regenerator (10) is compressed, the coolant flowing inside the first regenerator (10) is heated, and at the same time, the second regenerator (20) can cool the coolant flowing inside the second regenerator (20) by expanding.

[0176] In addition, when the second regenerator (20) is compressed, the coolant flowing inside the second regenerator (20) is heated, and at the same time, the first regenerator (10) can be expanded to cool the coolant flowing inside the first regenerator (10).

[0177] At this time, the first switching valve (70) can cause the cooling water cooled in the first regenerator (10) or the second regenerator (20) to flow to the first heat exchanger (50) through the first connecting pipe (95). Accordingly, the cooling water can cool the heating element in the first heat exchanger (50), and the cooling water can be heated by absorbing heat from the heating element. The cooling water heated in the first heat exchanger (50) can flow to the regenerator (10, 20) currently being expanded by passing through the second switching valve (80) through the third connecting pipe (97).

[0178] In addition, the first switching valve (70) can cause the cooling water heated in the first regenerator (10) or the second regenerator (20) to flow to the second heat exchanger (60) through the second connecting pipe (96). Accordingly, the cooling water can release heat in the second heat exchanger (60). The cooling water that has released heat in the second heat exchanger (60) can flow through the fourth connecting pipe (98) and pass through the second switching valve (80) to be introduced into the regenerator (10, 20) currently being compressed.

[0179]

[0180] Meanwhile, FIGS. 16 and 17 illustrate schematic diagrams for explaining an elastic heat cooling and heating system according to another embodiment of the present invention.

[0181] Referring to FIGS. 16 and 17, the elastic heat cooling and heating system of the present invention is described as follows.

[0182] To avoid repetitive explanations, details not specifically described in this embodiment may be used since they have the same structure and effect as the elastic heat cooling and heating system according to one embodiment of the present invention.

[0183] In this embodiment, the elastic heat cooling and heating system may be configured to provide heating through a second heat exchanger (60).

[0184] In this embodiment, the flow direction of the coolant may be reversed compared to one embodiment of the present invention. That is, the pump in this embodiment may provide a flow force so that the coolant flows into the first regenerator (10) through the first regenerator pipe (91) and the coolant discharged from the first regenerator (10) flows into the third regenerator pipe (93).

[0185] Additionally, the pump can provide a flow force so that the coolant flows into the second regenerator (20) through the second regenerator pipe (92) and the coolant discharged from the second regenerator (20) flows into the fourth regenerator pipe (94).

[0186] Additionally, the first heat exchanger (50) can receive cooling water cooled by the first regenerator (10) or the second regenerator (20). The first heat exchanger (50) can absorb external heat. In this case, if the first heat exchanger (50) is equipped with a fan, it can be used as an air conditioner. This can increase the overall energy efficiency.

[0187] Additionally, the second heat exchanger (60) according to one embodiment of the present invention can pass cooling water heated in the first regenerator (10) or the second regenerator. At this time, the second heat exchanger (60) can release heat to the outside. At this time, if the second heat exchanger (60) is equipped with a fan, it can be used as a heater. This can increase energy efficiency.

[0188] In an elastic heat capacity heating and cooling system of this configuration, the flow of coolant is described as follows.

[0189] When the hydraulic cylinder (40) is operated, the first regenerator (10) and the second regenerator (20) are compressed alternately.

[0190] Accordingly, when the first regenerator (10) is compressed, the coolant flowing inside the first regenerator (10) is heated, and at the same time, the second regenerator (20) can cool the coolant flowing inside the second regenerator (20) by expanding.

[0191] In addition, when the second regenerator (20) is compressed, the coolant flowing inside the second regenerator (20) is heated, and at the same time, the first regenerator (10) can be expanded to cool the coolant flowing inside the first regenerator (10).

[0192] At this time, the second switching valve (80) can cause the cooling water cooled in the first regenerator (10) or the second regenerator (20) to flow to the first heat exchanger (50) through the third connecting pipe (97). Accordingly, the cooling water can absorb external heat in the first heat exchanger (50). The cooling water that has absorbed heat in the first heat exchanger (50) can flow through the first connecting pipe (95) and pass through the first switching valve (70) to be introduced into the regenerator (10, 20) that is currently being expanded.

[0193] In addition, the second switching valve (80) can cause the cooling water heated in the first regenerator (10) or the second regenerator (20) to flow to the second heat exchanger (60) through the fourth connecting pipe (98). Accordingly, the cooling water can release heat in the second heat exchanger (60). The cooling water that has released heat in the second heat exchanger (60) can flow through the second connecting pipe (96) and pass through the second switching valve (70) to be introduced into the regenerator (10, 20) currently being compressed.
