[0021] Among them, a plurality of evenly distributed air outlet holes are opened inside the partition 3, the purpose of which is to facilitate the cold air blown out by the air cooler 5 to enter the top of the partition 3 through the air outlet holes, thereby facilitating rapid heat dissipation inside the switch box 1.

[0023] It should be noted that the partition 3 is provided to isolate the heat dissipation mechanism from the components inside the switch box 1 so that the heat dissipation mechanism will not damage the components inside the switch box 1 .

[0024] Among them, two fixing rods for support are fixedly installed on the inner bottom wall of the switch box 1, and the tops of the two fixing rods are fixedly connected to the bottom of the air outlet pipe 6, which can support the air outlet pipe 6, so that the air outlet pipe 6 can remain stable when in use.

[0025] The electrical components in the present invention are all electrically connected to an external main controller, and the main controller can be a conventional known device for controlling a computer, etc. The circuits and controls involved in the present invention are all prior art and will not be elaborated on here.

[0026] Specifically, by providing a heat dissipation mechanism, the purpose of dissipating heat inside the switch box 1 is achieved, so that the heat generated by the internal components of the switch box 1 can be quickly discharged, thereby avoiding safety hazards due to excessive temperature. By providing a cold air fan 5, an air outlet duct 6 and an air collecting hood 7, the purpose of quickly dissipating heat inside the switch box 1 is achieved. When the heat inside the switch box 1 is too high, the inside can be cooled down quickly to avoid damage to the components inside the switch box 1 and affect the service life.

[0027] like Figure 1 and Figure 2 As shown, in this embodiment, the heat dissipation mechanism includes a motor 801 fixedly mounted on the inner bottom wall of the switch box 1, the output shaft of the motor 801 is fixedly mounted with a rotating rod 802 through a coupling, the outer surface of the rotating rod 802 is fixedly mounted with a first fan blade 803, the outer surface of the rotating rod 802 is fixedly mounted with a first conical tooth 804, the left and right side walls of the inner cavity of the switch box 1 are rotatably mounted with connecting rods 805, the opposite sides of the two connecting rods 805 are fixedly mounted with a second conical tooth 806, and the two second conical teeth 80 The outer surfaces of 6 are meshed with the outer surfaces of the first conical teeth 804, and the left and right side walls of the inner cavity of the switch box 1 are rotatably installed with support pillars 807, and rollers 808 are fixedly installed between the outer surfaces of the two pillars 807 and the outer surfaces of the two connecting rods 805.

Their function is that the left second fan blade 810 and the right second fan blade 810 can quickly blow out the hot air inside the switch box 1 from the two heat dissipation nets 2, thereby making the heat dissipation effect better.

[0033] When the inside of the switch box 1 needs to be cooled, the air cooler 5 is first started, so that the cold air generated by the air cooler 5 enters the inside of the switch box 1 through the air outlet pipe 6 and the air collecting cover 7, and then the motor 801 is started. The motor 801 drives the rotating rod 802 to rotate, and the rotating rod 802 drives the first fan blade 803 to rotate. The first fan blade 803 blows the cold air discharged from the air outlet pipe 6 into the top of the partition 3 through the air outlet hole, which can quickly cool down the inside of the switch box 1. At the same time, the rotating rod 802 drives the first conical tooth 804 to rotate, and the first conical tooth 804 also drives the two second conical teeth 806 to rotate. The two second conical teeth 806 rotate. 06 respectively and simultaneously drive the two connecting rods 805 to rotate, the two connecting rods 805 respectively and simultaneously drive the two lower rollers 808 to rotate, the two lower rollers 808 respectively and simultaneously drive the two belts 809 for transmission, the two belts 809 respectively and simultaneously drive the two upper rollers 808 to rotate, the two upper rollers 808 respectively and simultaneously drive the two pillars 807 to rotate, the two pillars 807 respectively and simultaneously drive the two second fan blades 810 to rotate, the two second fan blades 810 blow the heat generated inside the switch box 1 to the outside of the switch box 1 through the two heat dissipation nets 2, thereby completing the heat dissipation work inside the switch box 1.
