Circulating heat exchange plate

The utility model discloses a circulation heat exchange plate which comprises a hollow heat exchange plate body, heat dissipation fins and a lifting mechanism, a flow channel for heat exchange media to circulate is arranged in the heat exchange plate body, the lifting mechanism is arranged on the surfaces of the heat dissipation fins through heat insulation pieces, and the heat dissipation fins are movably arranged on the surface of the heat exchange plate body. A pull rod on the lifting mechanism is hinged to the heat dissipation fins, and the heat dissipation fins are lifted up and down relative to the heat exchange plate under the action of the pull rod, so that contact and separation between the heat dissipation fins and the heat exchange plate are achieved. The heat exchanger has the advantages that the heat exchange medium is circularly injected into the S-shaped flow channel formed in the heat exchange plate to achieve the heating and cooling capacity of the heat exchange plate, temperature adjustment
