Description

Technical Field

[0001] The utility model relates to the field of PLC control cabinets, in particular to a PLC control cabinet capable of circulating ventilation and heat dissipation. Background Art

[0002] The PLC integrated control cabinet has protection functions such as overload, short circuit, and phase loss protection. It has a compact structure, stable operation, and complete functions. It can be combined according to the actual control scale, which can realize single cabinet automatic control, or multiple cabinets can form a distributed control system (DCS) through industrial Ethernet or industrial field bus network. PLC control cabinet can adapt to various large and small scale industrial automation control occasions. It is widely used in industries such as power, metallurgy, chemical industry, papermaking, environmental protection and sewage treatment.

[0003] After searching, the applicant found that a Chinese patent disclosed "a PLC control cabinet with circulating ventilation", and its announcement number is "CN216752575U". This patent mainly cooperates with a blower, an air duct, an air dispersion box, an exhaust port, a ventilation duct, a connecting rod, a motor and a fan. When the control cabinet works for a long time and the indoor temperature increases, the blower fixed on the upper end of the base is started. The air outlet of the blower is fixedly connected with an air duct. The air duct runs through the control cabinet and is connected to the air dispersion box. An exhaust port is provided on the surface of the air dispersion box. The blower conveys wind into the air dispersion box through the air duct, and then discharges the wind generated by the blower into the control cabinet evenly through the exhaust port. The motor is fixedly connected to the motor through a connecting rod in the ventilation duct. The motor shaft end is fixedly connected with a fan. When the motor rotates, the motor drives the fan to rotate, and the fan discharges the hot air in the control cabinet to the outside, so that the air in the control cabinet achieves a circulation effect and improves the flow of air.

[0004] Although the device in the above patent can dissipate heat to a certain extent inside the control cabinet, when the brush in the device in the above patent cleans the filter, the dust on the surface of the filter will be swept into the control box, and then the dust will cover the surface of the internal machine, resulting in reduced heat dissipation effect. During the use of internal components, the heat cannot be dissipated, which accelerates aging. Utility Model Content
