Heat conduction structure, finned tube heat exchanger and air conditioner

The utility model discloses a heat conduction structure, a finned tube heat exchanger and an air conditioner. The heat conduction structure comprises a heat conduction layer; the isolating layers comprise two first isolating layers which are arranged on the two sides of the heat conducting layer respectively, and the first isolating layers are arranged to have glass transition temperatures and can change between a glass state and a rubber state. When the heat conduction structure is applied to the finned tube heat exchanger, gaps between tube fins can be reduced, thermal resistance between the tube fins can be reduced, the heat conduction effect can be enhanced, galvanic corrosion between the tube fins can be reduced, and the service life of the finned tube heat exchanger can be prolonged.
