The side of the heat dissipation box 11 facing the circuit board is provided with a plurality of groups of suction pipes 13, the suction pipes 13 and the heat dissipation box 11 form sliding guide fit, and the outer circular surface of the suction pipes 13 is provided with a plurality of groups of suction holes and the suction holes are close to the free ends of the suction pipes 13.

The side of the heat dissipation box 11 is further provided with a heat conduction pipe 12, and the end of the heat conduction pipe 12 extends out of the casing.

The heat dissipation box 11 is further provided with a suction assembly for allowing air to enter the heat dissipation box 11 from the suction holes and to be discharged from the ends of the heat conductive pipes 12.

Specifically, as shown in fig. 5, the suction assembly includes a fan 18 coaxially disposed in the heat pipe 12, a motor 16 mounted on the outer surface of the heat dissipating box 11, and a power transmission member disposed between the output end of the motor 16 and the input end of the fan 18, wherein the motor 16 operates to rotate the fan 18 through the power transmission member, thereby sucking the air in the casing through the suction hole.

The heat dissipation process of the heat dissipation member 10 is specifically as follows:

the circuit board generates heat when working, so that the temperature of the surrounding air is higher;

the motor 16 drives the fan 18 to rotate through the rotating shaft 17 and the power transmission member a19, so that the air with raised temperature around the circuit board is discharged to the outside through the suction hole, the suction pipe 13, the heat dissipation box 11 and the heat conduction pipe 12 in sequence, and because the air near the circuit board is sucked to form negative pressure, the air in the machine shell flows to the vicinity of the circuit board under the action of the negative pressure, and the purpose of dissipating heat of the circuit board is achieved continuously;

in the above-mentioned radiating process, the flow of air is one-way to heat pipe 12 stretches out the casing, and is far away from the circuit board, so the heat that circuit board work produced is taken away by the single direction and can not take place the backward flow, and the air circumstance around the circuit board remains the room temperature all the time, makes the temperature of circuit board also keep the room temperature, and the radiating effect is better.

In addition, when the suction tube 13 is close to the component on the circuit board, the gear 24 is disengaged from the rack 25, and at the same time, the elastic force of the spring 15 drives the heat dissipation box 11 away from the circuit board, so that the gear 24 moves away from the circuit board and is engaged with the rack 25 again, that is, when the suction tube 13 is close to the circuit board, the motor 16 does not operate to pull the heat dissipation member 10 to move through the linkage member 20, and the gear 24 and the rack 25 are at the engagement critical point.

When the circuit board does not work, the motor 16 stops running, and the heat dissipation member 10 and the linkage member 20 both run reversely and reset.
