    The invention relates to a heat exchanger having at least one outer tube (1), a central tube (2) and an elongate inner body (3), wherein the inner body (3) is arranged in the interior of the central tube (2) and extends over at least part of the length of the Center tube (2) extends and the central tube (2) is arranged in the interior of the outer tube (1) and the central tube (2) extends over at least part of the length of the outer tube (1). Object of the present invention is thus to provide a heat exchanger having a low susceptibility to blockages. This is achieved in that at least in an inner space (5) between the inner body (3) and central tube (2) or in an outer space (4) between the central tube (2) and outer tube (1) at least one cleaning lip is arranged, and that the central tube (2) is rotatable with respect to the inner body (3) and / or the outer tube (1).

    Technically, the rotation of the heat exchange tube can be used, for example, by attaching a ring gear eye to a heat exchanger tube, which is attached by means of a spiral connection. The afotnr can be attached to an outer cylinder. Sealing of the liquids can be achieved by ring seals. The heat exchanger valve must be rotatably mounted there with a contraction bearing.
