Description

Technical Field

[0001] The utility model relates to the field of electrical control, in particular to a control cabinet. Background Art

[0002] A control cabinet is a closed or semi-closed cabinet that protects electrical equipment. With the current technical prospects of miniaturization and increasing integration of components, the density of components in the control cabinet is also gradually increasing. The heat generated by power devices in a confined space cannot be ignored. When the heat emitted by the components is accumulated in the control cabinet, the temperature in the control cabinet will be too high. Once the normal operating temperature range of the components is exceeded, it is very easy to cause the device to short-circuit and burn, or even cause a fire and cause a safety accident.

[0003] Therefore, the control cabinet is usually provided with a heat dissipation structure. However, since the components are usually installed on the back plate of the control cabinet, the actual heat dissipation effect of the components is poor.

The blowing fan is used to send cold air into the cabinet cavity. After the cold air is mixed with the hot air in the cabinet cavity and the heat in the heat dissipation module is taken away, the mixed air is discharged from the cabinet body by the blowing device to complete the heat dissipation and realize the cooling operation of the electronic components inside the cabinet cavity.
