[0002] Electrostatic precipitator uses high-voltage electric field to separate dust-containing gas, which can separate and remove dust inside the air and improve air quality. The normal operation of electrostatic precipitator cannot be separated from the control of the control cabinet. The working frequency of the electrostatic precipitator equipment can be adjusted through the control cabinet, so the variable frequency power supply control cabinet is an important equipment for electrostatic precipitator.

[0003] A Chinese patent discloses a variable frequency power supply control cabinet for electrostatic precipitator (Announcement No. CN215732793U). The patented technology can adsorb moisture inside the control cabinet body and evacuate the heat inside the control cabinet body, so that the heat dissipation effect inside the control cabinet body is better. In addition, during actual use, the outside of the control cabinet body can be protected to prevent the control cabinet body from being damaged by impact, thereby increasing the service life of the control cabinet body.

[0004] However, most of the existing control cabinets adopt direct fan cooling, which results in poor cooling effect, and when the internal temperature is high, the effect of only air cooling is not good, which easily leads to damage to the components inside the control cabinet. For example, the above-mentioned reference document adopts fan cooling. In actual application, when the temperature inside the control cabinet is high, only cooling by fan cannot achieve the purpose of efficient heat dissipation, and high temperature will still exist, causing damage to the components inside. Therefore, those skilled in the art provide a variable frequency power supply control cabinet for electrostatic precipitator to solve the problems raised in the above background technology.

The heat dissipation fan 34 inside the heat sink 3 can be used to draw in external air, and the air can be cooled through the cooling pipe 43, so that the purpose of efficiently dissipating heat inside the control cabinet main body 1 can be achieved, and the service life of the internal components of the control cabinet main body 1 can be improved.

[0023] like Figure 3As shown, the hot end of the refrigeration fin 41 is arranged outside the cooling box 4, and the cold end of the refrigeration fin 41 is arranged inside the cooling box 4. Cooling water is arranged inside the cooling box 4. A bracket 42 is also installed on the outside of the cooling box 4. An exhaust fan 421 is installed on one side of the bracket 42. This arrangement can use the refrigeration fin 41 to cool the cooling water inside the cooling box 4, thereby achieving the purpose of recycling.

[0024] like Figure 3 and Figure 4 As shown, a water pump is also provided inside the cooling box 4, and the water outlet end of the water pump is connected to one end of the cooling pipe 43. The cooling pipe 43 is arranged in an "S" shape inside the heat dissipation box 3, and the other end of the cooling pipe 43 is arranged on the rear surface of the cooling box 4. This arrangement can use the water pump to pump the cooling water inside the cooling box 4 to flow inside the cooling pipe 43, and can return to the inside of the cooling box 4 to be recycled.

[0025] like Figure 3 As shown, a heat dissipation fan 34 is also provided inside the heat dissipation box 3, and an air inlet 31 is provided on the outside of the heat dissipation box 3, and an exhaust hole is provided on the other side of the heat dissipation box 3 near the control cabinet body 1. This arrangement allows external air to be passed into the heat dissipation box 3 through the air inlet 31, and air can be passed into the control cabinet body 1 through the exhaust hole to achieve the purpose of heat dissipation inside the control cabinet body 1.
