Description

technical field [0001] The invention relates to an electrical device, in particular to a semi-conductor cooling and dust-proof power distribution cabinet. Background technique [0002] The power distribution cabinet is the final equipment of the power distribution system, and it is the general name of the motor control center. The heat generated by the electrical components installed in the power distribution cabinet needs to be discharged continuously to ensure the normal operation of the electrical components. At present, the heat dissipation method and structure of the electrical components in the power distribution cabinet have the following defects: 1. Since the power distribution cabinets are generally high in height, vertical ventilation is adopted, the air path is long, and the cold air at the end of the air path has been blocked. Heating, so the temperature in the power distribution cabinet is still high, and the heat dissipation effect is poor, resulting in shorte...

AI Technical Summary

Problems solved by technology

At present, the heat dissipation method and structure of the electrical components in the power distribution cabinet have the following defects: 1. Since the power distribution cabinets are generally high in height, vertical ventilation is adopted, the air path is long, and the cold air at the end of the air path has been blocked. Heating, so the temperature in the power distribution cabinet is still high, and the heat dissipation effect is poor, resulting in shortened service life of electrical components; 2. There is more dust at the air inlet of the air duct, so that the wind entering the power distribution cabinet carries more dust; 3. 1. After the electrical components are used for a long time, dust is easy to accumulate in the depressions and irregular protrusions of the electrical components, reducing the service life of the electrical components and forming a safety hazard (possibly causing a short circuit); 4. The air volume of the air circuit is not adjusted. Mechanism, high energy consumption, low cooling efficiency
