A heat dissipation structure configured to couple with an interface card is provided. The heat dissipation structure comprises a first heat conduction portion arranged above a first surface of a wired board of the interface card, a second heat conduction portion arranged above a second surface of the wired board opposite the first surface thereof, and a heat convection portion connecting the first and the second heat conduction portions. Both the first and the second heat conduction portions comprise a plurality of contact leads used to contact the heat-generating electronic components disposed on the two surfaces of the wired board. The heat convection portion has a plurality of first bending strips and a plurality of second bending strips that are alternatively arranged, and a plurality of heat convection slots are formed between the first bending strips and the second bending strips.
