置が大型化する。Since the heat exchange is carried out on the surface of the metal fiber, it can be said that the efficiency is higher as the surface area of the wire of the metal fiber is larger. However, when the wire diameter of the metal fiber is increased in order to increase the surface area, the weight increases in proportion to the increase in the surface area. Further, if the mesh is made fine to increase the wire extension, the ventilation resistance increases, and if the wire extension is attempted to be increased without increasing the ventilation resistance, the device becomes large.

It is an object of the present invention to provide a metal fiber used for a heat exchanger, a catalyst, or the like, which can improve efficiency without increasing the weight and size of the device.

に基づいて本発明の構成を詳細に説明する。DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The structure of the present invention will be described in detail below with reference to specific embodiments shown in the accompanying drawings.

から構成される。FIG. 1 shows an L-type Stirling engine to which the present invention is applied. This Stirling engine 1
A high temperature cylinder 3 that defines a high temperature space that is heated by the heater 2 and maintains a high temperature, a displacer piston 4 that reciprocates in the cylinder 3, and a low temperature that defines a low temperature space that is cooled by a cooler 5 and maintains a low temperature. It is composed of a cylinder 6 and a power piston 7 that reciprocates in the cylinder 6, and a regenerator 8 that exchanges heat of the transfer gas between the heater 2 and the cooler 5.

クーラ５へ送り、その逆にクーラ５からのガスは加熱し
てヒータ２へと送る。The regenerator 8 is formed by laminating meshes made of metal fibers according to the present invention. When the heated gas enters from the heater 2 side, the heat is absorbed to lower the gas temperature and send it to the cooler 5. On the contrary, the gas from the cooler 5 is heated and sent to the heater 2.

関係しないので、ここではこれ以上の説明は割愛する。Since the Stirling cycle is a reversible cycle, power can be taken out from the power piston 7 side if heat is supplied, and conversely, if power is supplied to drive the power piston 7, heat is pumped up. be able to. Specifically, when the crankshaft 9 continues to rotate in the same direction without heating the high temperature cylinder 3 during expansion, heat is continuously absorbed from the heating side. However, since the heat is not supplied, the temperature on the heating side decreases, and the temperature becomes lower than room temperature, thus exhibiting the function as a refrigerator. Incidentally, the Stirling cycle itself is known, and since it is not directly related to the essence of the present invention, further description will be omitted here.
【００１１】このようなスターリングサイクル等の熱交
換効率を高めるには、再生器８（熱交換機）の比熱が小
さく、伝熱面積が大きく、しかもガスの流動抵抗が小さ
いことが求められる。In order to improve the heat exchange efficiency of such Stirling cycle, it is required that the regenerator 8 (heat exchanger) has a small specific heat, a large heat transfer area, and a small gas flow resistance.

い。FIG. 2 shows the cross-sectional shape of the metal fiber strand of the present invention. The strand 10 has a groove 11 having a substantially V-shaped cross section which is recessed from the outer surface toward the center along the axial direction. The groove bottom may be rounded with an appropriate curvature r as shown in FIG. 2, or may be an acute angle.

（μｍ） となる。これと同一断面積の真円の周長は、 １９．４×π＝６０．９（μｍ） なので、両者の比は、 ７９．３／６０．９＝１．３０ となり、これより同一断面積にて表面積を約３０％増大
できることが分かる。Comparing the surface areas of the grooved one and the perfect circular contour having the same cross-sectional area, the diameter D = 20 μm,
When the groove opening angle θ = 20 °, the groove bottom round radius r = 0, and the distance a = 0 between the cross-sectional center of the metal fiber and the groove bottom, the perimeter is 20 × π × 340 ° / 360 ° + 10 + 10. = 79.3
(Μm). Since the circumference of a perfect circle having the same cross-sectional area is 19.4 x π = 60.9 (μm), the ratio of the two is 79.3 / 60.9 = 1.30, which gives the same cross-sectional area. It can be seen that the surface area can be increased by about 30%.

Further, the present invention is not limited to the regenerator of the above Stirling engine, but can be widely applied to general heat exchangers, catalysts, magnetic filters, surface combustion burners, and the like.
