1. A heat dissipation structure of an optical transceiver, comprising:
a housing, having an accommodating space, the housing extending along a lengthwise direction and divided into an exposed section and a hidden section in the lengthwise direction;
a frame, fitted with the exposed section and the hidden section, the frame defining an exposed opening at a location corresponding to the exposed section and a hidden opening at a location corresponding to the hidden section;
a uniform heat component, extending along the lengthwise direction and in contact with a bottom surface of the frame,
wherein an exposed part of the uniform heat component is fitted within the exposed opening,
wherein the exposed part comprises a plurality of projecting features, and
wherein a hidden part of the uniform heat component extends beneath the hidden opening;
an outer fin, disposed at the exposed section and in thermal contact with the uniform heat component via a plurality of fins,
wherein a fin, of the plurality of fins, has a fin tip that is in contact with a projecting tip of a projecting feature of the plurality of projecting features, and
wherein the plurality of fins coordinate with the plurality of projecting features to form a plurality of airflow passages in the lengthwise direction; and
an elastic clamping component, clamping both sides of the outer fin in a widthwise direction which is perpendicular to the lengthwise direction, the elastic clamping component having a pushing member in the lengthwise direction, wherein the pushing member pushes the frame to move the outer fin inward along the lengthwise direction.
