In a housing, a clothes dryer wherein dampness in washed clothes is expelled by warm air sweeping therethrough, the air being drawn in at least partly from the environment through openings formed in the housing and heated and, after absorbing the dampness, exhausted at least partly back into the environment, the air drawn in from the environment and exhausted to the environment being conducted through two channels of a heat exchanger with a solid-body regenerator alternatingly contacted in part by the drawn-in air and the exhausted air, the improvement therein including non-hygroscopic storage material received in the regenerator and absorbing thermal energy as loss-free as possible, storing the absorbed thermal energy as loss-free as possible and subsequently surrendering the thermal energy as loss-free as possible, the regenerator being air-permeable in axial direction thereof and being mounted in the drawn-in and exhausted air channels for rotation in a manner that every region of the regenerator is alternatingly introduced into the drawn-in air channel and into the exhaust air channel during the rotation.
