The utility model discloses an efficient heat regeneration device. The heat regeneration device comprises a heat regenerator sleeve and axial filler inside the heat regenerator sleeve, wherein the axial filler is an entirety formed by an etching metal sheet in a wrapping mode, the etching metal sheet comprises a plurality of non-etching cross bars, a plurality of vertical bars with half-etching front faces, and a plurality of connecting arms with half-etching back faces, each vertical bar is arranged at one side of each cross bar, and each connecting arm is installed between two vertical bars which are adjacent and not connected. The heat regeneration device can lower loss of flow resistance, and reduces volume of the heat regenerator. The etching style of the heat regeneration device extends heat conduction path and reduces heat conduction area, and therefore axial heat conduction loss is reduced.
