Definitions

  • the present invention relates to a regenerator for use in a Stirling-cycle refrigerator or the like, and relates also to a flow gas heat regeneration system employing such a regenerator
  • a type of conventional regenerator 1 for use in a Stirling-cycle refrigerator is, for example as shown in Fig. 8, composed of a resin film 2, having fine projections 2a formed on the surface thereof, rolled into a cylindrical shape with a hollow space left inside it.
  • Fig. 9 is a side sectional view of an example of a free-piston-type Stirling-cycle refrigerator incorporating the regenerator 1.
  • the free-piston-type Stirling-cycle refrigerator includes a cylinder 8 having a working gas such as helium sealed therein, a displacer 7 and a piston 5 arranged so as to divide the space inside the cylinder 8 into an expansion space 10 and a compression space 9, a linear motor 6 for driving the piston 5 to reciprocate, a heat absorber 14 provided on the expansion space 10 side for absorbing heat from outside, and a heat rejector 13 disposed on the compression space 9 side for rejecting heat to outside.
  • reference numerals 11 and 12 represent plate springs that support the displacer 7 and the piston 5, respectively, and permit them to reciprocate by resilience.
  • Reference numeral 15 represents a heat rejecting heat exchanger
  • reference numeral 16 represents a heat absorbing heat exchanger. These heat exchangers prompt exchange of heat between inside and outside the refrigerator. Between the heat rejecting heat exchanger 15 and the heat absorbing heat exchanger 16, a regenerator 1 is disposed.
  • the working gas that has flowed into the expansion space 10 is under high pressure, and is expanded when the displacer 7, which reciprocates with a predetermined phase difference kept relative to the piston 5, moves down. Meanwhile, the temperature of the working gas falls, but the working gas is heated through absorption of heat from the outside air by the heat absorber 14 through the heat absorbing heat exchanger 16. Thus, isothermal expansion is achieved. Thereafter, the displacer 7 starts moving up, and thus the working gas in the expansion space 10 flows through the regenerator 1 back into the compression space 9. Meanwhile, the working gas receives the heat stored in the regenerator 1, and thus the temperature of the working gas rises.
  • This sequence of operations called the Stirling cycle, is repeated by the reciprocating movement of the driven components, with the result that the heat absorber 14 absorbs heat from the outside air and gradually becomes cold.
  • an object of the present invention is to provide a regenerator that offers excellent heat energy regeneration efficiency and stable regeneration performance.
  • DE 3240598 discloses a rotating heat recovery device which has a matrix formed from plastic. Dimensions of the matrix are adapted to specific dimensional parameters, and the matrix strip is equipped with transverse bulges which have a length that is less than the strip width, in order to permit a wind-up tension to act on the strip without influencing the dimensions of the bulges.
  • the dimensional parameters permitted by the use of plastic permit the production of matrix discs having a minimum thickness which reduces the circumferential leakage loss.
  • a regenerator composed of a strip-shaped resin film rolled into a cylindrical shape, the resin film has a multiple layer structure at least in a portion thereof occupying a predetermined width from an edge thereof. This helps increase the strength of the edges of the regenerator so that they are less prone to deformation, and thus helps stabilise the performance of the regenerator.
  • the layer having high thermal conductivity formed on the resin film enhances heat conduction in the regenerator. Thus, more heat is stored in the resin film.
  • the layer having high thermal conductivity formed on the resin film enhances heat conduction in the regenerator 1 and provides higher heat capacity. Thus more heat is rejected to the working gas. In this way, it is possible to achieve high heat energy regeneration efficiency.
  • the resin film may have a plurality of fine projections formed on the surface thereof. This leaves gaps between different turns of the resin film laid on one another, and thus permits the working gas to flow through those gaps from the high-temperature end to the low-temperature end and vice versa along the cylinder axis.
  • the regenerator composed of a strip-shaped resin film rolled into a cylindrical shape
  • the resin film is composed of two strip-shaped resin films having a layer with higher thermal conductivity than the two resin films laminated between the two resin films. This helps avoid exposing the layer having high thermal conductivity to outside.
  • the layer having high thermal conductivity on the resin film helps reduce the area, and this the material costs and the like, of the layer having high thermal conductivity compared with a case where the layer having high thermal conductivity is formed all over the resin film.
  • the layer having high thermal conductivity can be formed easily by being printed on the resin film as resin ink containing an ingredient having high thermal conductivity.
  • suitable as the ingredient having high thermal conductivity is fine particles of at least one of gold, silver, copper, aluminium, and carbon.
  • regenerator of the present invention By disposing the regenerator of the present invention in a doughnut-shaped space serving as a flow pass for a reciprocating gas, it is possible to realise a versatile flow gas heat regeneration system that offers high heat energy regeneration efficiency.
  • the present invention by applying the present invention to a free-piston-type Stirling-cycle refrigerator, it is possible to achieve excellent refrigerating performance.
  • Fig. 1 is a perspective view showing the structure of the regenerator of the first embodiment of the invention
  • Fig. 2 is an enlarged sectional view of the regenerator.
  • the regenerator 1 is composed of a strip-shaped resin film 2 rolled into a cylindrical shape.
  • the resin film 2 is formed out of a material having high specific heat, low thermal conductivity, high heat resistance, low moisture absorption, and other desirable properties, suitable examples including polyethylene terephthalate (PET) and polyimide.
  • the resin film 2 has a plurality of fine projections 2a formed regularly all over one surface thereof. These projections 2a can be formed, for example, by printing, embossing, or heat forming. As shown in Fig. 2, the projections 2a permit gaps to be left between different turns of the resin film 2 laid on one another. Thus, through these gaps, as shown in Fig. 1, the working gas flows from the high-temperature end 1H to the low-temperature end 1C as indicated by an arrow A and vice versa along the cylinder axis (the direction indicated by a dash-and-dot line B).
  • resin layers 3 containing an ingredient having higher thermal conductivity than the resin film 2 are formed as thin films.
  • Suitable as the ingredient having high thermal conductivity is fine particles of gold, silver, copper, aluminum, carbon, or the like used singly or as a mixture of two or more of them.
  • the fine particles are mixed with a resin material such as polyethylene, and the mixture is then printed, as ink, on both surfaces of the resin film 2 to coat it with the resin layers 3.
  • Fig. 3 is a perspective view showing the structure of the regenerator of the second embodiment of the invention.
  • the resin film 2 has a plurality of fine projections 2a formed regularly all over one surface thereof These projections 2a permit gaps to be left between different turns of the resin film 2 laid on one another. Thus, through these gaps, the working gas flows from the high-temperature end 1H to the low-temperature end 1C as indicated by an arrow A and vice versa along the cylinder axis (the direction indicated by a dash-and-dot line B).
  • resin layers 3 containing an ingredient having higher thermal conductivity than the resin film 2 are formed in the shape of stripes arranged at regular intervals along the cylinder axis.
  • masks are laid beforehand in the shape of stripes arranged at regular intervals. Then, coating is performed just as in the first embodiment. Lastly, the masks are washed off and removed to obtain the resin layers 3.
  • the stripes of the resin layers 3 may be arranged at irregular intervals.
  • the resin layers 3 on the resin film 2 are formed in the shape of stripes arranged at intervals. This helps reduce the loss of heat during heat conduction through the resin layers 3 from the high-temperature end 1H to the low-temperature end 1C. Moreover, the resin layers 3 have a smaller area than when they are formed all over the resin film 2. This helps reduce the amount of the high-thermal-conductivity ingredient used, and thus helps reduce costs.
  • the portions where the resin layers 3 are not formed have comparatively low thermal conductivity, since the resin layers 3 are formed in the shape of stripes, by determining the widths and intervals of the stripes of the resin layers 3 so that the working gas makes as little contact as possible with those low-thermal-conductivity portions, it is possible to minimize the lowering of heat energy regeneration efficiency.
  • Fig. 4 is a perspective view showing the structure of the regenerator of the third embodiment of the invention.
  • the resin film 2 has a plurality of fine projections 2a formed regularly all over one surface thereof These projections 2a permit gaps to be left between different turns of the resin film 2 laid on one another.
  • the working gas flows from the high-temperature end 1H to the low-temperature end 1C as indicated by an arrow A and vice versa along the cylinder axis (the direction indicated by a dash-and-dot line B).
  • the portions of the regenerator 1 around the high-temperature end 1H and the low-temperature end 1C thereof contribute to heat energy regeneration to a particularly high degree.
  • resin layers 3 containing an ingredient having higher thermal conductivity than the resin film 2 are formed so as to occupy a predetermined width from each edge of the regenerator 1 by the same process as in the second embodiment.
  • the resin layers 3 on the resin film 2 are formed to occupy a predetermined width from each edge of the regenerator 1, and thus have a smaller area than when they are formed all over. This helps accordingly reduce the amount of the high-thermal-conductivity ingredient used, and thus helps reduce costs. Moreover, since these portions of the regenerator 1 contribute to heat energy regeneration to a high degree, almost no lowering in the performance of the regenerator 1 results.
  • FIG. 5 is a perspective view showing the structure of the regenerator of the fourth embodiment of the invention.
  • resin layers 3 containing an ingredient having higher thermal conductivity than the resin film 2 are formed in the shape of stripes arranged at regular intervals along the cylinder axis so as to occupy a predetermined width from each edge of the regenerator 1.
  • the resin layers 3 on the resin film 2 are formed at intervals so as to occupy a predetermined width from each edge of the regenerator 1, and thus have a smaller area than when they are formed all over. This helps accordingly reduce the amount of the high-thermal-conductivity ingredient used, and thus helps reduce costs. Moreover, since these portions of the regenerator 1 contribute to heat energy regeneration to a high degree, almost no lowering in the performance of the regenerator 1 results.
  • the resin film 2 is described as having the resin layers 3 formed on both surfaces thereof
  • FIG. 6 is a perspective view showing the structure of the regenerator of the fifth embodiment of the invention.
  • resin coatings 4 of polyethylene or the like are formed so as to occupy a predetermined width from each edge of the regenerator 1.
  • masks are laid beforehand. Then, a resin material is printed as ink on both surfaces of the resin film 2 to achieve coating. Lastly, the masks are washed off and removed to obtain the resin coatings 4.
  • the portions of the resin film 2 occupying a predetermined width from each edge thereof, i.e., the portions that contribute to heat energy regeneration to a high degree, are made thicker. This not only helps increase heat storage capacity and thereby enhance heat energy regeneration efficiency, but also helps make the resin film 2 less prone to develop wrinkles when rolled up.
  • the resin film 2 is described as having the resin coatings 4 formed on both surfaces thereof.
  • Fig. 7 is an enlarged sectional view showing the regenerator of the sixth embodiment of the invention.
  • the regenerator 1 is composed of a composite resin film 20 rolled into a cylindrical shape.
  • the composite resin film 20 is composed of two strip-shaped resin films 21 and 22 having a resin layer 3, described later, laminated between them.
  • One resin film 21 has a plurality of fine projections 2a formed regularly all over one surface thereof As shown in Fig. 7, these projections 2a permit gaps to be left between different turns of the composite resin film 20 laid on one another.
  • the working gas flows from the high-temperature end 1H to the low-temperature end 1C as indicated by an arrow A and vice versa along the cylinder axis.
  • a resin layer 3 having higher thermal conductivity than the resin film 22 is formed as a thin film.
  • the two resin films 21 and 22 are laid together so that the surface of the resin film 22 on which the resin layer 3 is formed is kept in intimate contact with the surface of the resin film 21 on which the projections 2a are not formed. In this way, the composite resin film 20 having the resin layer 3 laminated inside it is produced.
  • the resin layer 3 is not exposed to outside, and therefore it never drops off. This greatly enhances durability.
  • the laminated resin layer 3 may be formed in stripes arranged at predetermined intervals along the cylinder axis as shown in Fig. 3, or may be formed so as to occupy a predetermined width from each edge of the regenerator 1 as shown in Fig. 4, or may be formed in stripes arranged at predetermined intervals along the cylinder axis so as to occupy a predetermined width from each edge of the regenerator 1 as shown in Fig. 5.
  • the resin layer or layers 3 are described as being printed as ink. However, they may be formed by any other method, such as painting, vapor deposition, plating, or application of a thin film tape.
  • regenerator 1 structured as described above in a doughnut-shaped space to constitute a system in which a gas is made to flow through that space in a reciprocating fashion, it is possible to realize a versatile flow gas heat regeneration system as exemplified by a ftee-piston-type Stirling-cycle refrigerator.
  • a layer having higher thermal conductivity than the resin film is formed, or altematively a resin coating is formed so as to occupy a predetermined width from an edge of the regenerator.
  • This increases heat conduction in the regenerator and stabilizes the performance thereof.
  • a flow gas heat regeneration system having this regenerator disposed in a doughnut-shaped space, when a hot working gas flows into the regenerator through one end thereof, the heat of the working gas is stored in the resin film.
  • the layer having high thermal conductivity or the resin coating formed on the resin film enhances heat conduction in the regenerator. Thus, more heat is stored in the resin film.
  • the layer having high thermal conductivity or the resin coating formed on the resin film enhances heat conduction in the regenerator and increases the heat capacity thereof. Thus, more heat is rejected to the working gas. In this way, it is possible to achieve high heat energy regeneration efficiency.
  • regenerator of the present invention when applied to a free-piston-type Stirling-cycle refrigerator, it is possible to achieve excellent refrigerating performance.
