[0031] The solution of this embodiment provides a strong heat dissipation type high-voltage switch cabinet, including a cabinet body 1, a shield 2, an inner lining plate 6, a first air guide plate 9 and a second air guide plate 11. The cabinet body 1 has a cabinet door 5 that opens outward, and the cabinet door 5 is equipped with a display screen, an indicator light, and a button switch. The cabinet body 1 is provided with a plurality of first heat dissipation ports 4, as shown in detail. Figure 1As shown in the figure, the first heat dissipation openings 4 are arranged in an equidistant array, and a rain shield can be arranged outside the first heat dissipation openings 4, and the cabinet 1 has an upward vent 101, and a symmetrically arranged sealing plate 12 is arranged at the lower part of the vent 101, and the sealing plate 12 can be opened, and the upper and lower surfaces of the sealing plate 12 are provided with sealing gaskets with the same shape as the vent 101; the shield 2 is arranged at the upper part of the cabinet 1, and the shield 2 covers the vent 101, and the shield 2 is provided with a gasket for providing air to the inside of the cabinet 1 The fan blade 302 of the flow power is installed on the driving end 301 of the driving motor 3; the inner lining plate 6 is arranged inside the cabinet 1, and the inner lining plate 6 and the inner wall of the cabinet 1 are arranged at a preset distance to form a cavity, and the cavity can form a flow channel for the gas, and the inner lining plate 6 is provided with a second heat dissipation port 601 corresponding to the first heat dissipation port 4, and the second heat dissipation port 601 is arranged opposite to the first heat dissipation port 4; the first air guide plate 9 and the second air guide plate 11 are hinged with the first heat dissipation port 4 and the second heat dissipation port 601, and the first A connecting rod 10 for connecting the first air guide plate 9 and the second air guide plate 11 is provided between the air guide plate 9 and the second air guide plate 11. During use, when the first air guide plate 9 is opened, the second air guide plate 11 closes the second heat dissipation port 601 through the drive of the connecting rod 10. At this time, the sealing plate 12 at the vent 101 is closed, and the air flow flows outside the inner lining plate 6 to reduce the temperature inside the cabinet 1. If the internal temperature is too high, the sealing plate 12 is opened, so that the air flow generated by the fan blades 302 is directly blown to the inside of the cabinet 1. At this time, as the sealing plate 12 is opened, The first heat dissipation port 4 is gradually closed, and the second heat dissipation port 601 is opened. The gas generated from the upper part of the cabinet 1 blows directly to the middle part of the cabinet 1. The airflow is blown out from the second heat dissipation port 601, and then passes through the one-way valve hole 15 at one end of the sealing plate 12, and is exchanged through the heat dissipation wire 8 or the heat exchange tube arranged inside the supporting cross tube 14. Heat is exchanged through the heat exchange tube, and heat dissipation is performed inside the cabinet 1.

When the first air guide plate 9 and the second air guide plate 11 are in the same direction, the wind blown out is the same, and when they are in a half-open state at the same time, they can accelerate the hot air in the cabinet 1 to fill the entire cavity, form a strong pressure in the cavity, and accelerate the discharge of gas from the cabinet 1.

[0034] It should be further explained that the opening directions of the first air guide plate 9 and the second air guide plate 11 are both within the cavity formed by the inner lining plate 6 and the inner wall of the cabinet 1, and the air guiding directions of the first air guide plate 9 and the second air guide plate 11 are opposite, and the openings of the first air guide plate 9 and the second air guide plate 11 are relative to each other, thereby guiding the hot air in the cabinet 1 to be directly discharged from the cabinet 1.
