Regenerator and regenerative material used therein

Abstract

The present invention provides a regenerator which has uniform performance and extremely high productivity and can keep performance and reliability as a regenerator, as well as a regenerative material used in the regenerator, in order to solve technical problems in mass production. A mat type regenerative material is woven into a cloth shape by using flexible and very long fine wires (C1, C2) made of one or a plurality of heat storage materials having a high specific heat per unit volume in the operating temperature range, for longitudinal wire members (C1, C2); and fine wires (D3) comprising a core wire consisting either of a single filament (D1) of at least one of ceramic fiber, carbon fiber, and synthetic resin fiber which have a higher hardness than that of the longitudinal wire members, a proper elasticity, and an extremely low heat conductivity, or of a filament composite (D2) formed by bundling a number of the same filaments as the single filament into one body with a fixing agent such as synthetic resin or glass, and a polymeric synthetic resin covering the core wire, for transverse wire members (D3).
