DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] Embodiment 1, as Figure 1-4 As shown, a high and low voltage switch cabinet for convenient air circulation is shown. The low voltage switch cabinet utilizes the cooperation of the shutters 7 and the ventilation fan 6 to make the air circulation in the cabinet stronger. The external air enters the filter bin through the shutters 7, and is input into the interior of the box through the ventilation top window 12 on the lower side after filtering the dust, while the air in the box is discharged out of the box through the ventilation fan 6, so as to achieve the effect of maintaining air circulation in the box, thereby accelerating the cooling efficiency and making the equipment more durable. The shutters 7 are set to allow the switch cabinet to be effectively ventilated to avoid excessive temperature, and the filter bin 8 with the shutters 7 is internally installed with a filter plate 13, which can block impurities such as dust and gravel in the air, and keep the box clean during ventilation to avoid damage to the equipment. The shutters 7 and the filter plates 13 are both detachable. The screws are removed to open the shutters 7, and the filter plates 13 can be taken out by the sliding structure through the mounting rails 14 on both sides of the filter plates 13. The installation and replacement are convenient, and the filter plates 13 can be replaced and cleaned at any time, saving costs.

[0023] Embodiment 2, as Figure 1-4 As shown, a high and low voltage switch cabinet is provided for convenient air circulation. The staff can monitor the operation of the equipment through the display screen 3 and the indicator light group 4 on the front cabinet door 2 to ensure the safety of the instrument. The cooling bellows 15 and the cooling fan 9 are provided to achieve a full range of cooling effect in the cabinet 1. The cabinet 1 can be cooled by the fan 17 in the cooling bellows 15. At the same time, the cooling fan 9 at the bottom of the cabinet 1 can further accelerate the cooling process. The hollow structure of the support frame 5 accelerates the heat dissipation, so that the cooling efficiency of the device is high. The bottom plate 10 is used to carry equipment in the box to make the internal equipment more dispersed, thereby freeing up more space for arranging lines to avoid crowded equipment arrangement affecting the heat dissipation effect.

[0024] How it works

[0025] It should be noted that the utility model is a high- and low-voltage switch cabinet that facilitates air circulation. When in use, the shutters 7 and the ventilation fan 6 cooperate with each other to make the air circulation in the cabinet stronger. The external air enters the filter bin through the shutters 7, and is input into the interior of the cabinet through the ventilation top window 12 on the lower side after filtering the dust, while the air in the cabinet is discharged out of the cabinet through the ventilation fan 6, thereby achieving the effect of maintaining air circulation in the cabinet, thereby accelerating the cooling efficiency and making the equipment more durable. The shutters 7 are set to allow the switch cabinet to be effectively ventilated to avoid excessive temperature, and the filter bin 8 with shutters 7 is equipped with a filter plate 13, which can block impurities such as dust and gravel in the air, and keep the cabinet clean during ventilation to avoid damage to the equipment. The shutters 7 and the filter plate 13 are both detachable. The design is to remove the screws to open the shutter 7, and the filter plate 13 can be taken out by the sliding structure through the installation slide rails 14 on both sides of the filter plate 13. The installation and replacement are convenient, and the staff can monitor the operation of the equipment through the display screen 3 and the indicator light group 4 on the front cabinet door 2 to ensure the safety of the instrument. The cooling bellows 15 and the cooling fan 9 provided can achieve a full range of cooling effect in the cabinet 1, and the cabinet 1 can be air-cooled and dissipated by the fan 17 in the cooling bellows 15. At the same time, the cooling fan 9 at the bottom of the cabinet 1 can further accelerate the cooling process, and the hollow structure of the support frame 5 accelerates the heat dissipation, so that the cooling efficiency of the device is high. The bottom plate 10 is used to carry equipment in the box, so that the internal equipment is more dispersed, thereby freeing up more space for arranging lines and avoiding crowded equipment arrangement.
