Description

Technical Field

[0001] The invention relates to the technical field of control cabinets, in particular to a control cabinet with good heat dissipation performance. Background Art

[0002] Control cabinet is a common electrical equipment and an important part of the power system. The control cabinet is assembled in a closed or semi-closed metal cabinet or on a screen according to the electrical wiring requirements to realize power control and transmission.

[0003] Various electrical modules installed inside the electrical cabinet will generate a lot of heat during operation. The large amount of heat accumulation will cause the temperature inside the electrical cabinet to rise, thus affecting the normal operation of the electrical cabinet. In order to dissipate the heat in time, air cooling is usually adopted, that is, the top or side panels of the electrical cabinet are usually provided with heat dissipation holes and heat dissipation fans as air circulation channels. This structure has many problems when used:

[0004] First, when the heat dissipation fan and the heat dissipation holes work at the same time, the air outside the cabinet enters the cabinet through the heat dissipation holes, and the hot air inside the cabinet is discharged from the inside of the cabinet through the heat dissipation fan. However, in this structure, due to the heat dissipation holes, dust from the outside can easily enter the cabinet through the heat dissipation holes, and the electrical modules in the cabinet can easily be dirty, affecting their performance and service life. Secondly, in rainy weather, the air-cooled heat dissipation device will allow some moisture or rainwater to enter the control cabinet through the heat dissipation port, causing damage to the electrical components inside the controller, resulting in serious consequences. In addition, the heat dissipation fan cannot reduce the temperature below room temperature, especially when the temperature outside the control cabinet is high, the fan cannot effectively cool the inside of the cabinet. Therefore, in view of the above situation, it is urgent to develop a control cabinet with good heat dissipation performance to overcome the shortcomings in current practical applications. Summary of the invention
