Heat regenerator device

The utility model relates to the technical field of heat regenerators, in particular to a heat regenerator sleeve and a heat regenerator, which comprises a heat regenerator body, a heat exchange liquid conveying mechanism is arranged inside the heat regenerator body, and a heat conduction sleeve body for conducting heat on the heat regenerator body is arranged outside the heat regenerator body. The conveying auger is additionally arranged in the heat regenerator shell to convey high-pressure liquid, so that the time of the high-pressure liquid passing through the interior of the heat regenerator shell is prolonged, the contact time of the high-pressure liquid and refrigerant steam is prolonged, the refrigerant steam is in full contact with the high-pressure liquid, and the heat exchange efficiency is improved; and an aluminum heat conduction sleeve body is additionally arranged outside the heat regenerator shell, heat of the heat regenerator shell is guided out and conducted to a heat conduction block through
