Abstract
The invention relates to a heat dissipation structure of a set-top box, and the set-top box. An oblique fan and a fan carrier are arranged between a PCB and an upper casing, a wind passage is formed in the fan carrier, wind from the fan is led to heat dissipation pieces which are opposite to a wind outlet through the wind passage, and the wind takes away heat on the heat dissipation pieces so as to accelerate the heat dissipation of the heat dissipation pieces; as the oblique fan is additionally arranged on the side edges of the heat dissipation pieces, large heat dissipation pieces are not needed, so that a heat dissipation structure can be used in a relatively small set-top box, the heat of the set-top box can be effectively dissipated, the condition that the set-top box is not damaged and normally works is guaranteed, and the service life of the set-top box is prolonged.
