Heat dissipation structure of optical transceiver and optical transceiver

A heat dissipation structure of an optical transceiver comprises a shell, a frame, a soaking component, an outer fin and an elastic clamping component, the shell is provided with a containing space, the shell extends in the length direction and is divided into an exposed section and a built-in section in the length direction, the frame is clamped with the exposed section and the built-in section, openings are formed in the positions, corresponding to the exposed section and the built-in section, of the frame respectively, and the outer fin is arranged in the containing space. The soaking component is clamped in the opening, the portion, corresponding to the built-in section, of the soaking component is embedded in the containing space, the heat conduction protruding block is arranged in the containing space and makes thermal contact with the soaking component, and the outer fin is arranged on the exposed section and makes thermal contact with the soaking component. The elastic clamping components clamp the tw
