At the open ends of the cylindrical housing 11, a punch plate 13 having a large number of holes is fixed by TIG (tungsten inert gas) welding.

A compression space (not shown) is connected via the punch plate 13, and an expansion space (not shown) is connected to the other end (lower end in the drawing) via the punch plate 13. Therefore, the working gas such as helium enclosed in the compression space or the expansion space moves vertically in the drawing through the punch plate 13.

る。As shown in FIG. 2, a plurality of thin tubes 12 are arranged in the cylindrical housing 11 adjacent to each other, and are located in parallel to the moving direction of the working gas (that is, the vertical direction in the drawing). ing. Both ends of the thin tube 12 are fitted to the punch plate 13. The inner diameter and the outer diameter of the thin tube 12 are 0.1 to 0.2 mm and 0.4 mm, respectively.
【００１４】上記の如く構成されたスターリング機関用
蓄熱器１０の作用について説明する。The operation of the Stirling engine heat storage device 10 configured as described above will be described.

その結果、作動ガスは、昇温する。When the relatively high temperature working gas in the expansion space is compressed and moves to the compression space, the heat of the working gas is transferred to the adjacent thin tubes 12 in the heat storage device 10 to be stored in the thin tubes 12. . As a result, the temperature of the working gas drops. On the other hand, when the relatively low temperature working gas in the compression space is compressed and moves to the expansion space, the heat stored in the thin tube 12 in the heat storage device 10 is applied to the working gas moving in the housing 11. .
As a result, the temperature of the working gas rises.
