Description

Technical Field

[0001] The utility model relates to the technical field of electrical cabinets, in particular to an active heat dissipation type intelligent electrical cabinet. Background Art

[0002] Electrical cabinets are made of steel to protect the normal operation of components. Electrical cabinets are generally made of hot-rolled steel plates and cold-rolled steel plates. Cold-rolled steel plates are softer than hot-rolled steel plates and are more suitable for the production of electrical cabinets. Electrical cabinets are widely used in the chemical industry, environmental protection industry, power system, metallurgical system, industry, nuclear power industry, fire safety monitoring, transportation industry, etc. Intelligent electrical cabinets are intelligent electrical cabinets that are processed to cope with various situations that may occur in electrical cabinets.

[0003] The existing Chinese utility model patent with reference announcement number CN219959782U discloses an intelligent electrical cabinet, which relates to the field of electrical cabinets. The electrical cabinet mechanism includes a shell, and a partition located inside the shell for dividing the inner cavity space of the shell. The dehumidifier is fixed on the side wall of the partition in the electrical cabinet mechanism. The utility model has a simple structure. During operation, the electrical equipment in the shell works through the dehumidifier on the partition, and absorbs the air outside the shell through the air inlet pipe to form dry air, which is discharged into the shell from the air outlet pipe to form air flow inside the shell. The dry air carries the wet air inside the shell and is discharged from the air vent to keep the inside of the shell dry, thereby protecting the electrical equipment inside the shell and preventing it from being damaged by erosion by the wet air. At the same time, the operation of the dehumidifier causes the flow of air inside the shell, which can lead the heat generated by the electrical equipment inside the shell out of the shell, effectively dissipate the heat, protect the safety of the electrical equipment, and improve its service life.

[0004] Existing electrical cabinets generally add an opening structure on the surface of the cabinet to form gas exchange between the inside of the cabinet and the outside, thereby removing the heat inside the cabinet. This method has limited heat dissipation effect and may cause external dust or fine particles to enter the cabinet. Utility Model Content
