Description

Technical Field

[0001] The utility model relates to the field of control cabinets, in particular to an industrial PLC control cabinet with an external heat dissipation mechanism. Background Art

[0002] Industrial PLC control cabinet is a device specially designed for industrial automation control system. PLC stands for programmable logic controller, which is a computing device used to monitor input signals, execute preset tasks and control output signals, so as to realize the automatic control of industrial processes. In the process of using existing control cabinets, the electronic components and equipment inside the control cabinet are usually prone to generate a lot of heat. Since the control cabinet is cooled by a separate fan, the temperature inside it continues to rise after long-term operation, resulting in accumulation of temperature inside the control cabinet, which is not easy to dissipate, affecting the normal operation and life of the equipment. Therefore, we proposed an industrial PLC control cabinet with an external heat dissipation mechanism to solve the above problems. Utility Model Content

[0025] When working, first manually grasp the pull plate and slide it along the outer end of the limit block 303 along the combined fixed rod to pick it up, manually pull the pull handle 302 and the hinge 304 to rotate and open the sealing cover 301, use the three-group hinge 304 to connect the sealing plate to open and close the sealed cabinet 1, effectively prevent dust, moisture, corrosive gases, etc. from entering the cabinet, and protect the internal components from damage. After the sealing cover 301 is opened, the equipment is assembled inside the cabinet 1, and the sealing cover 301 is manually closed again to fit and seal the cabinet 1, and the operation of the cabinet 1 is started. When the cabinet 1 is running, the internal electronic components and equipment will generate heat after working for a long time, and at the same time, multiple sets of rotating motors 204 are started to drive the rotating rod 205 to drive the fan blades 206 along The rotating slot rotates inside, and multiple sets of fan blades 206 are used to transfer the heat inside the box to the outer end. The wind can quickly take away the heat inside the control cabinet, so that the temperature of the control cabinet can be reduced to a safe range in time. At the same time, the rotating motor 204 can control the fan blades 206 to evenly dissipate the heat inside the control cabinet, so that the heat can be effectively transmitted and dissipated from all directions and regions to avoid local high temperature. When the fan blades 206 dissipate heat inside the cabinet 1, dustproof plates 203 are installed at the fan ventilation position to prevent dust, effectively prevent dust and particulate matter from entering the control cabinet when air flows, protect the electronic equipment and components in the control cabinet from dust corrosion and blockage, and reduce dust accumulation inside the control cabinet.

When the fan stably dissipates heat, the shock-absorbing spring 402 combined with the movable rod 401 absorbs the vibration generated by the heat dissipation device during operation, relieves the stress generated by the equipment during operation, and avoids damage to internal parts by vibration. While the fan dissipates heat to the inside of the cabinet 1, the transmission pipe 502 transfers the coolant from the cooling box to the cooling pipe 503 and circulates along the inside of the cabinet 1. The generated cold air cools the inside of the cabinet 1. At the same time, during the flow of the coolant, the air pump 504 is started to draw back the coolant in the cooling pipe 503 to form a reflux for secondary use. After being processed by the cooling box, it is injected into the cooling pipe 503 again by the transmission pipe 502 for circulation cooling. A closed-loop cooling system is adopted to ensure that the coolant is always in a circulating state, thereby achieving sufficient heat dissipation of the industrial PLC control cabinet.

[0027] Through the above steps, by using multiple sets of rotating motors 204 to drive the rotating rods 205 to drive the fan blades 206 to transfer the internal heat of the box to the outer end, the wind can quickly take away the heat inside the control cabinet, so that the temperature of the control cabinet is reduced to a safe range, and the configuration of the multiple sets of rotating motors 204 and the fan blades 206 can ensure that the heat inside the entire control cabinet is evenly dissipated. By reasonably arranging and adjusting the position of the fan blades 206, the heat can be effectively transmitted and dissipated from all directions and regions to avoid local high temperature phenomena. By installing dustproof plates 203 at the fan ventilation points for dust prevention, fine particles such as dust and particulate matter can be effectively prevented from entering the control cabinet, and the electronic equipment and components in the control cabinet are protected from dust corrosion and clogging, thereby improving the reliability of the equipment and extending the life of the equipment. At the same time, the dustproof plates 203 can reduce the accumulation of dust inside the control cabinet and reduce the frequency of cleaning and maintenance. The cabinet 1 is sealed by connecting the sealing plate with the three-combination page 304, which effectively prevents dust, moisture, corrosive gas and the like from entering the cabinet and protects the internal components from damage. The vibration generated by the heat dissipation device during operation is absorbed by the shock-absorbing spring 402 in combination with the movable rod 401, thereby improving the stability of the equipment operation. At the same time, the shock-absorbing spring 402 can relieve the stress generated by the equipment during operation, avoid damage to internal parts by vibration, reduce the failure rate of the equipment, and extend the service life of the cabinet 1. The coolant is transmitted to the cooling pipe 503 by the transmission pipe 502 to cool the inside of the cabinet 1. At the same time, the coolant is pumped back by the air pump 504 for reflux and secondary use. After treatment, it is injected into the cooling pipe 503 again for circulation cooling, which reduces energy consumption, is beneficial to saving resources and protecting the environment, and adopts a closed-loop cooling system so that the coolant is always in a circulating state to improve the heat dissipation effect.
