Technical Field

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

[0002] The control cabinet is a device that assembles switchgear, measuring instruments, protective electrical appliances and auxiliary equipment in a closed or semi-closed metal cabinet or on a screen according to the requirements of electrical wiring. Its layout should meet the requirements of normal operation of the power system, facilitate maintenance, and not endanger the safety of people and surrounding equipment. During normal operation, the circuit can be connected or disconnected with the help of manual or automatic switches.

[0003] After searching the patent document with the announcement number CN220253936U, the patent document discloses "a highly efficient heat dissipation automatic electrical control cabinet, which absorbs heat from four directions of the cabinet body, namely, up, down, left, and right, through four heat-absorbing plates, and then cools the cooling liquid after absorbing the heat. In comparison, the cooling of the interior of the control cabinet will be more uniform, so that the cooling effect of the interior of the control cabinet can be effectively guaranteed, and the function is more perfect in use";

[0004] The above device achieves good heat dissipation effect in the control cabinet through the combination of air cooling and water cooling. The principle of air cooling is to extract the heat inside the device and draw the air with lower temperature outside the device into the device, thereby realizing the heat dissipation inside the control cabinet. The above device is only provided with multiple ventilation holes on the upper end of the cabinet, and the cooling fan is also installed on the upper end of the cabinet. This will easily lead to the cooling fan operating, and the air with lower temperature that has just entered the device will be drawn out of the device, resulting in poor air cooling effect of the above device.
