Definitions
- Regenerator manufacturing method of regenerator and manufacturing apparatus of regenerator
- the present invention relates to a regenerator formed by laminating film-like resin members, a method and an apparatus for producing the regenerator, and a Stirling refrigerator having the regenerator.
- the Stirling engine is an external combustion engine that realizes a Stirling cycle, which is a reversible cycle, using an external heat source, and compared to an internal combustion engine that requires a fuel with excellent flammable and ignition properties, such as gasoline. It is a heat engine with excellent advantages of energy saving and low pollution.
- a Stirling refrigerator is widely known as an application example of this Stirling engine.
- This Stirling refrigerator is a refrigerator that generates cryogenic temperatures using a reverse Stirling cycle.
- the structure of the Stirling refrigerator will be described below with reference to the drawings.
- the Stirling refrigerator includes a cylinder 20 filled with inert gas such as hydrogen or helium as a working gas.
- a piston 27 and a displacer 26 are fitted in the cylinder 20, and a space in the cylinder 20 is divided into a compression chamber 28 and an expansion chamber 29 by these.
- the piston 27 is driven by the linear motor 30 but is periodically and sinusoidally moved in the cylinder 20 because it is connected to the body casing 23 by the spring 32.
- the displacer 26 reciprocates in the cylinder 20 under the force of the sinusoidal motion of the piston 27 but it is connected to the main casing 23 by the spring 31 like the piston 27. It will take a periodic sinusoidal motion.
- the sine motion of this piston 2 7 and the sine motion of the displacer 2 6 have the same circumference during steady operation. It is performed with a constant phase difference in time.
- a regenerator 15 is disposed between the compression chamber 28 and the expansion chamber 29.
- the two chambers communicate with each other through the regenerator 15 to form a closed circuit in the refrigerator.
- a heat dissipation heat exchanger 24 is attached to the side of the compression chamber 28 of the closed circuit, and a radiator 22 is provided adjacent to the heat dissipation heat exchanger 24.
- a heat absorbing heat exchanger 25 is attached to the expansion chamber 29 side of the closed circuit, and a heat absorber 21 is provided adjacent to the heat absorbing heat exchanger 25.
- the reverse Stirling cycle is realized by the working gas in the closed circuit flowing according to the operation of the piston 27 and the displacer 26.
- the radiator 22 plays a role of releasing the heat in the compression chamber 28 to the outside
- the heat exchanger 24 for radiating plays a role of promoting the radiation.
- the heat absorber 21 plays a role of transferring external heat into the expansion chamber 29, and the heat absorbing heat exchanger 25 plays a role of promoting this heat transfer.
- the operation of the above-described Stirling refrigerator will be described. First, operate linear motor 30 and drive piston 27.
- the piston 27 driven by the re-air motor 30 approaches the displacer 26 and compresses the working gas in the compression chamber 28.
- the temperature of the working gas in the compression chamber 28 is increased, but the heat generated in the compression chamber 28 by the radiator 22 via the heat radiation heat exchanger 24 is released to the outside.
- the working gas temperature in the compression chamber 28 is maintained approximately isothermally. That is, this process constitutes an isothermal compression process of the reverse Stirling cycle.
- the high pressure working gas that has flowed into the expansion chamber 29 is expanded by the downward movement of the displacer 26.
- the working gas temperature in the expansion chamber 29 drops, the external heat is transferred to the inside of the expansion chamber 29 by the heat absorber 21 via the heat absorbing heat exchanger 25, so the expansion chamber The temperature in 29 is kept almost isothermal. That is, this process constitutes the isothermal expansion process of the reverse Stirling cycle.
- the displacer 26 starts to rise, the working gas in the expansion chamber 29 passes through the regenerator 15 and returns to the compression chamber 28 side again. At that time, the heat amount stored in the regenerator 15 is given to the working gas, so the working gas is heated. That is, this process constitutes the equal volume heating process of the reverse Stirling cycle.
- a reverse Stirling cycle is configured by repeating this series of processes (isothermal compression process one equal volume cooling process one isothermal expansion process one equal volume heating process). As a result, the heat sink 21 gradually cools down to a cryogenic temperature.
- the regenerator is a type of heat exchanger as described above, and is a device that exchanges heat with the working gas flowing in the regenerator. For this reason, it is necessary to secure a larger contact area with the working gas in the limited space. On the other hand, if a complicated route is configured to secure a large contact area, it will be a resistance to the flow of the working gas, which will lead to a reduction in the efficiency of the Stirling refrigerator. That is, as the internal structure of the regenerator, it is preferable that the heat transfer area in contact with the working gas be large and the flow resistance be small. For this reason, in the regenerator, various fin structures have conventionally been proposed.
