[0024] Refer to Figure 1 , a flow valve 9 is installed on the liquid inlet pipe 8. Such a setting facilitates the staff to control the flow rate of the coolant in the liquid inlet pipe 8 by adjusting the flow valve 9, thereby avoiding waste while ensuring the cooling effect.

[0025] Furthermore, the flow valve 9 is an electromagnetic valve, and the flow valve 9 is electrically connected to the operation box 7. Such a setting facilitates the staff to directly set the flow rate of the flow valve 9 through the operation box 7, with high flexibility, simple operation, and convenience.

[0026] Refer to Figure 1 , an observation window 4 is arranged on each material door 2. A handle 3 is arranged on the material door 2. A sealing strip is laid between the material door 2 and the cooling cabinet 1. Such a setting facilitates opening and closing the material door 2 by using the handle 3, so as to put in and take out materials.

The electromagnet 14 converts electrical energy into a magnetic field, and the magnetic field exerts an adsorption effect on the electrical hardware placed in the cooling cabinet 1. Adjust the position of the sliding rheostat switch 703 to adjust the magnetic field strength of the electromagnet 14, so that the electrical hardware in the cooling cabinet 1 is in a floating state with the corners touching the ground. At this time, the coolant injected through the liquid inlet pipe 8 is split into two shunt pipes 12 on both sides of the electromagnet 14 through the three-way valve 11, and is atomized by the electromagnet 14 and then sprayed out to perform an all-round cooling treatment on the electrical hardware. The coolant after heat exchange is re-liquefied and discharged through the liquid discharge pipe 10 for recovery treatment.
