For example, in a heat exchanger used as a regenerator of a pulse tube refrigerator, cooling has been known. The heat of the part is transferred to the outside. For example, in the pulse tube refrigerator shown in FIG. 6, a regenerator 1 in which a member is packed between a pulse tube 2 and a cylinder 3 so as to allow a gas to move and increase a contact area with the gas is provided. It is interposed.

In this pulse tube refrigerator, a piston 4 reciprocates in a cylinder 3 to repeatedly compress and expand the gas in the pulse tube 2 and a phase difference between the movement of the piston 4 and the compression and expansion of the gas. (Ideally 90 °), heat is exchanged in the regenerator 1, and the heat removed from the cooling section 2a at one end of the pulse tube 2 is transferred to the outside.

In FIG. 6, reference numeral 5 denotes an orifice, and reference numeral 6 denotes a buffer tank, which constitutes means for controlling a phase difference between movement of the piston 4 and compression / expansion of gas.

For example, the temperature of the cooling section 2a at one end is 70 K, while the temperature at the other end is about room temperature. This is one of the factors hindering improvement in efficiency. Second, the insertion (filling) of the mesh plate into the casing is performed manually, and the number of mesh plates is enormous, from several hundred to several thousand. There is a problem that causes an increase in management, manufacturing time and cost.

Therefore, the present invention reduces the heat conduction loss in the gas moving direction by eliminating the heat conduction due to the contact of the members contacting the gas moving inside, thereby reducing the cooling capacity and cooling efficiency.

Here, when the gap between the plates is set to be large, the number of plates to be filled in the regenerator is reduced and the heat exchange capacity is reduced, so that the gap is as narrow as possible (for example, 10 μm or less). It is desirable to set and increase the number of laminations. Next, a first embodiment of a method for manufacturing a heat exchanger according to the present invention will be described with reference to FIG.

The filling operation can be further facilitated.

Next, a fourth embodiment of the method for manufacturing a heat exchanger according to the present invention will be described with reference to FIG. First,
As shown in FIG. 5A, a circular plate 31 provided with a hole 36 at a specific location in the inner surface area, for example, at the center, is formed. Then, as shown in FIG. 31 are stacked. Here, it is assumed that a resist 33 is applied to one surface of the plate in the same manner as in the above-described manufacturing method.

Next, as shown in FIG. 5 (c), an adhesive 34 is inserted into the opening 36 and joined to form an integrated plate assembly 30.

It may be formed by etching a thin plate material having a high thermal conductivity and a high heat capacity, such as a mesh plate or a stainless thin plate or a copper thin plate.

Here, the mesh plate may have a thickness of, for example, 60 to 100 μm, and the etching plate may have a thickness of, for example, 30 to 100 μm. In addition, a method of manufacturing a combined body using an etching plate includes, for example, applying a resist to a plate, patterning the plate, performing etching by a known etching method, and forming a plate having a desired slit shape and outer shape. After laminating and bonding with the resist remaining, the exposed resist is removed with a resist solvent to form a plate assembly 30 in which the plates are separated with a desired gap. According to such a manufacturing method, the step of applying the resist can be omitted by sharing the resist used for the etching and the resist for forming the gap, so that the operation efficiency can be improved.

In each of the above-described embodiments, the surface on which the resist 33 is applied is not limited to one surface of the plate, but may be both surfaces of the plate.

Further, in each of the above-described embodiments, the shape of the plate constituting the plate assembly 30 is circular.
The present invention is not limited to this, and may have a polygonal shape, for example.

As a resist for forming a gap between the circular plates, for example, a photosensitive rubber-based resin can be used, and as a solvent, xylene can be used. Furthermore, although a resist is used in the above-described embodiment of the manufacturing method, the present invention is not limited to this, and any paste or solid material can be used as long as its state changes to liquid or gas by a solution or the like.
