[0002] A programmable control cabinet refers to a PLC control cabinet. A control cabinet refers to a complete set of control cabinets, which can realize the electrical cabinets for motor and switch control. By importing the programmed PLC program into the control cabinet, the actual operation of the control cabinet can be simplified, and it is widely used in industries such as electric power, metallurgy, chemical industry, papermaking, environmental protection sewage treatment, and mining (corresponding qualifications are required for underground applications).

[0003] In the process of using the existing programmable control cabinets in industrial and mining enterprises, due to a large number of electrical components installed in the cabinet body, during long-term use, the internal heat dissipation performance is not good.
