Definitions

  • the present invention relates to a cooler, and more particularly, to a regenerator for a cooler provided with a heat accumulation member having uniform ventilation and improved heat transfer performance.
  • a cooler is an apparatus for generating cooling effect through the processes of compression, expansion, etc. of working fluid, such as helium, hydrogen or the like. Such a cooler is used to cool small-sized electronic goods or superconductor material to an ultra low temperature .
  • a heat regenerating type cooler such as Stirling cooler and GM cooler is mainly used as a cooler. In these coolers, reliability is enhanced by lowering the operation speed, changing the shape of a rubbed sealing material or removing moving parts.
  • it is required to develop a cryogenic cooler with a high reliability so that there is no need to repair for a long period of time. As a result, the lubricationless pulse tube cooler is developed.
  • the lubricationless pulse tube cooler is an apparatus to implement cryogenic refrigeration at an open end of a tube by using the principle in which a gas having a constant temperature is periodically injected into the tube one end of which is closed and thus the pressure is changed. If the turbulence component in the gas flow is small, a very great temperature gradient is obtained.
  • FIG. 1 illustrates a cooler according to the conventional art. Referring to FIG. 1, a cooler includes a driving part 100, a radiating part 200 and a refrigerating part
  • the driving part 100 compresses a coolant gas through linear reciprocating movement of a piston 140 by electromagnetic interaction of a linear motor 130 into high temperature and pressure state.
  • the driving part 100 includes a shell tube 120, a linear motor 130, a piston 140, a cylinder 150, a leaf spring 160 and a spring support 170.
  • the shell tube 120 has a space therein, and is fixedly coupled with a frame 110 with concentrically circled with inner/outer radiating parts 210, 220 having a displacer 310 inserted therein.
  • the linear motor 130 includes a stator 130a and an armature 130b, and is installed in the shell tube 120.
  • the piston 140 is fixed to one end of the armature 130b of the linear motor 130 so that linear reciprocating movement is made by the electromagnetic mutual interaction of the linear motor 130.
  • the cylinder 150 is fixedly coupled with a frame 110 at the center in the inside the frame 110 such that the linear reciprocating movement of the piston 140 that is inserted therein with concentric to the inner radiating part 210 is evenly transmitted to the displacer 310.
  • the leaf spring 160 is fixedly supported at an end of a displacer rod 320 such that the position of the displacer rod 320 inserted into the piston 140 is concentric with the piston 140 and the inner radiating part 210.
  • the radiator part 200 includes the inner radiating part 210 fixed to the frame 110 of the external circumferential surface of the displacer 310 to absorb the heat of the coolant gas compressed in high temperature and high pressure by the piston 140, and the outer radiating part 220 fixed to the external circumferential surface of the inner radiating part 210, for radiating the heat of the coolant gas transmitted from the inner radiating part 210 to the outside of the cooler 10.
  • the refrigerator part 300 includes the displacer 310, a regenerator 330 and a cooling side part 350.
  • the displacer 310 is formed as one body with the displacer rod 320 and fixedly inserted into the inner radiating part 210 to perform the linear reciprocating movement within the elastic deformation range of the leaf spring 160 fixed at one end of the displacer rod 320 through compression of the coolant gas pressed by the piston 140.
  • the regenerator 330 coupled with the displacer 310 accumulates the sensible heat of the coolant gas in high temperature and high pressure state and compressed and delivered into the displacer
  • the regenerator 330 transmits the heat to the coolant gas in a low temperature expanded in an expansion space thereby compensating for the temperature of the coolant gas.
  • the cooler 1 constructed as above is described hereinafter.
  • electromagnetic interaction of the stator 130a and the armature 130b allows the armature 130b to move linearly.
  • This linear movement also makes the piston 140 fixed at one end of the armature 130b to move linearly.
  • the linear movement of the piston 140 allows the coolant gas, such as helium or hydrogen stored in the compression space, to be compressed.
  • a portion of the compressed coolant gas is released out of the cooler 10 via the radiating part 200, and the other portion is injected into the regenerator
  • the displacer 310 linearly moves into the expansion space by the compressed coolant gas.
  • the compressed gas injected into the regenerator 330 delivers heat to store thermal energy while the gas passes through the regenerator 330, and moves into the expansion space.
  • the compressive force of the piston 140 is reduced, so that the displacer 310 moves into the compression space through linear reciprocating movement.
  • the coolant gas that has moved into the expansion space is cooled to an ultra low temperature state .
  • the expanded coolant gas in low temperature state is given the accumulated heat while passing through the regenerator 330 into the compression space.
  • the cooler performs cooling operation by repeating the above-described operation cycle. [0009] As shown in FIG.
  • the regenerator 330 coupled with the displacer 310 includes a housing 340 concentrically coupled with a cylinder of the displacer 310, a heat accumulation member 344 inserted to the inside of the housing 340, and an end cap 348 adhered to a front end of the housing 340.
  • the heat accumulation member 344 contacts with the coolant gas to exchange heat.
  • the heat accumulation member 344 receives energy from the coolant gas to store the energy and return it back. So, it is desired that the heat accumulation member 344 has a large heat exchanging area and a great specific heat, and is made of the material that has a low heat transfer coefficient.
  • the heat accumulation member 344 is made in a soft powder type, a small ball type or a random wire type.
  • each type of the heat accumulation members 344 depends on the temperature band in which the cooler is used.
  • the random wire type heat accumulation member made of stainless material is usually employed for the regenerator of the cooler used for cryogenic refrigeration of about 77 °K.
  • the random wire type heat accumulation member is made in the form of a bundle of fine wires. Accordingly, in order to insert the random wire heat accumulation member into the regenerator, the random wire heat accumulation member is made using a die considering its structural characteristic and inserted into the housing. [0011]
  • the regenerator to which the conventional random wire type heat accumulation member is applied is high in cost and takes too much time to allow the random wire type heat accumulation member that has a random shape to have a concrete shape.
  • the random wire Since the random wire is bundled, the heat transfer is so easy that the efficiency of the regenerator is lowered.
  • the random wire type heat accumulation member is inserted into the housing of the regenerator, the heat accumulation members are not uniformly pressed throughout the whole area of the housing at the same interval.
  • the random wires having a specific shape, inserted first into the housing are pushed by a portion of the random wires inserted later into the housing, the random wires at the rear portion of the inside of the housing are highly dense and the random wires at the front portion of the inside of the housing are low dense. Therefore, the uniform ventilation is not maintained throughout the whole housing, thereby the cooler performance is lowered.
  • the present invention is directed to a regenerator for a cooler that substantially obviates one or more problems due to limitations and disadvantages of the related art.
  • An object of the present invention is to provide a regenerator for a cooler provided with a heat accumulation member including a plurality of stacked mats made in a housing by a vacuum sintering method.
