Abstract:
1. A heat dissipation structure applied to an interface card, wherein the interface card has a wired board and a first heat-generating electronic component, and the first heat-generating electronic component is arranged on a first surface of the wired board, the heat dissipation structure comprising: a first heat conduction portion, arranged above the first surface of the wired board, wherein the first heat conduction portion has a first contact lead protruding from the first heat conduction portion to contact the first heat-generating electronic component, contacting part of the first contact lead, contacting the heat-generating electronic component, and the first heat conduction portion are in different levels respectively, an extending part of the first contact lead, connected between the contacting part and the first heat conduction portion, and the contacting part are internally formed, and the first heat conduction portion has a first connection lead protruding from the first heat conduction portion to connect the first surface of the wired board; a second heat conduction portion, arranged above a second surface of the wired board opposite the first surface; and a heat convection portion, crossing an edge of the wired board to connect the first heat conduction portion and the second heat conduction portion, wherein the heat convection portion has multiple heat convection slots.
