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.

Description

technical field [0001] The invention relates to a heat dissipation structure, in particular to a heat dissipation structure of a set-top box and the set-top box. Background technique [0002] At present, when the set-top box is in use, it will generate a lot of heat, which needs to be dissipated in time, otherwise the internal temperature will be too high and the set-top box will be damaged. [0003] The traditional heat dissipation method of the set-top box is to use metal heat sinks to dissipate heat through the metal heat dissipation fins to achieve the purpose of heat dissipation. However, this heat dissipation solution requires the heat dissipation fins to have a large heat dissipation area in order to ensure that the heat can be fully dissipated into the air, which leads to the increase in the height of the heat dissipation fins, so it is difficult to apply this heat dissipation method to a relatively small box. Inside the set-top box, the heat cannot be effectively d...
