[0071] like Figure 7 As shown, the heat sink 20 forms an air guide channel on the air guide plate 30; Figure 4 As shown, one end of the air guide channel faces the first heat dissipation hole 11, and the other end faces the second heat dissipation hole 12; the fan 40 is arranged at one end of the air guide channel; the fanning direction of the fan 40 is set along the length direction of the air guide channel.

[0072] During heat dissipation, the air guide channel is arranged between the first heat dissipation hole 11 and the second heat dissipation hole 12 which are arranged opposite to each other, so as to achieve good convection effect and good heat dissipation effect;

[0073] When the heat sink 20 conducts heat from the first heat source, the heat is discharged from the nearby first heat dissipation hole 11 or the second heat dissipation hole 12 through the combination of the wind force of the fan 40 and the air guide channel, thereby discharging the hot air to the outside of the director box body 10, thereby solving the problem that hot air is easily accumulated inside the director box in the existing director box heat dissipation structure, causing the temperature inside the director box to rise.

[0074] The director box provided by the embodiment of the present invention integrates the functions of special effects processing, wireless Bluetooth, fan heat dissipation automatic control and touch screen, and achieves good heat dissipation effect through the director box body 10, the first heat dissipation hole 11, the second heat dissipation hole 12, the heat sink 20, the air guide plate 30, the fan 40, the air guide channel and its position structure design, which can effectively solve the problem of excessive temperature inside the director box.

[0078] When implementing it specifically, Figure 7 As shown, the air deflector 30 is provided with flanges 31 on both sides; threaded struts 52 are provided around the heat sink 20; the fins 21 on both sides of the heat sink 20 are lower than the fins 21 in other locations; when the bolts 53 pass through the flanges 31 and are threadedly connected to the threaded struts 52, the flanges 31 press against the fins 21 on both sides of the heat sink 20, thereby fixing the heat sink 20 to the first heat source. The fixing structure of this embodiment can reduce the escape of hot air from the sides to the inner wall of the director box body 10.

[0079] Furthermore, a second heat source is provided on the air guide plate 30; the second heat source is a module with small heat dissipation in the multi-functional director box circuit.

[0080] In specific implementation, although the second heat source does not emit as much heat as the first heat source, in order to maintain the efficient operation of the entire circuit, a fan is still required to be set up for heat dissipation. Figure 7 As shown, the second heat source is set on the air guide plate 30, and the heat is dissipated by convection at the first heat dissipation hole 11 and the second heat dissipation hole 12 or the air outlet of the fan 40 is simultaneously aimed at the second heat source and the air guide channel, thereby reducing the number of fans 40 and solving production costs.

[0084] In a specific implementation, the second heat source is located at both ends or one end of the threaded support 52 and is movably connected to the surface of the wind deflector 30 through a structure such as a rotating shaft. By combining the movable second heat source with the wind guide groove structure, when the wind passes through the second heat source, the second heat source can fluctuate or swing, thereby improving the heat dissipation effect.
