A semiconductor refrigeration sheet is provided on the water tank 3. The heat dissipation pipe 6 is arranged as a U-shaped pipe. The cold end of the semiconductor refrigeration sheet is used to cool the water resource inside the water tank 3. The pump body 4 is started to deliver cold water to the delivery pipe 5, and the delivery pipe 5 then delivers the cold water into the heat dissipation pipe 6. The blower 12 is started to dissipate heat from the outer surface of the electrical bin 9, improving the use stability of the electrical equipment inside the electrical bin 9.

[0023] Please refer to Figures 2 - 5 , an electrical bin 9 is provided inside the placement bin 2. A groove 8 is provided inside the electrical bin 9. A sealing gasket 16 is fitted inside the groove 8. One side of the sealing gasket 16 is connected to a sealing door 15. The sealing gasket 16 on the sealing door 15 is fitted into the groove 8 inside the electrical bin 9. A detection block 7 is provided inside the groove 8. A contact piece B 20 is provided inside the detection block 7. A guide block 21 is connected inside the detection block 7 through a spring 18. One side of the guide block 21 is connected to a contact piece A 19. The sealing gasket 16 presses against the guide block 21, causing the guide block 21 to compress the spring 18, so that the contact piece A 19 contacts the contact piece B 20. When the elastic force of the sealing gasket 16 weakens, the contact piece A 19 disengages from the contact piece B 20 under the action of the spring 18, so that the contact piece B 20 can timely transmit a signal to notify the staff, facilitating the staff to understand the sealing state and improving the use safety. Connecting blocks 17 are provided on both the sealing door 15 and the electrical bin 9. The two groups of connecting blocks 17 are connected by bolts, facilitating the connection of the sealing door 15 and the electrical bin 9.

[0025] Working principle: By placing the electrical equipment in the electrical compartment 9, fitting the gasket 16 on the sealing door 15 into the groove 8 inside the electrical compartment 9, the gasket 16 presses against the guide block 21, causing the guide block 21 to compress the spring 18, so that the contact piece A19 contacts the contact piece B20. When the elasticity of the gasket 16 weakens, under the action of the spring 18, the contact piece A19 disengages from the contact piece B20, and thus the contact piece B20 promptly transmits a signal to notify the staff, facilitating the staff to understand the sealing state. At this time, nitrogen gas inside the nitrogen tank 10 is flushed into the interior of the electrical compartment 9, and the air inside the electrical compartment 9 is discharged through the one-way valve 11. The cold end of the semiconductor refrigeration sheet is used to cool the water resources inside the water tank 3. The pump body 4 is started to convey the cold water to the conveying pipe 5, and the conveying pipe 5 then conveys the cold water into the heat dissipation pipe 6. The fan 12 is started to dissipate heat from the outer surface of the electrical compartment 9, improving the use stability of the electrical equipment inside the electrical compartment 9.
