Combined dynamic spoiler plug-in

The invention discloses a combined dynamic spoiler plug-in, which is used in a heat exchange tube of heat exchange equipment, and is characterized by comprising a spoiler carrier ring (1) and more than two dynamic spoilers (2); the spoiler carrier ring (1) is used for being matched with the inner surface of the heat exchange tube in a use state, and the dynamic spoilers (2) are arranged on the spoiler carrier ring (1); and in the use state, the dynamic spoilers (2) can swing relative to the spoiler carrier ring (1) under the action of a flowing working medium in the heat exchange tube. The combined dynamic spoiler plug-in provided by the invention has the beneficial effects that the dynamic spoilers which swing under the action of the flowing working medium are more suitable for a fluid working medium containing dust or other particles with a certain concentration on the basis that the turbulence degree is enhanced, the development of a near-wall surface fluid boundary layer is disturbed and destroyed, and th
