Considering various factors, water cooling is generally used. However, the existing water-cooling circulation tube coil is on the side of the furnace body and has no protective mechanism. It is easy to be damaged by external factors (impact, dust accumulation, corrosion). For example, a Chinese patent discloses "a medium frequency electric furnace water cooling device", and its application number is: "202121655 014.9”, it turns on the first fan to exhaust the hot air near the condenser box, and turns on the second fan to draw air from the outside of the box, so that the heat of the water vapor is released and converted into water to flow back to the water tank through the return pipe, so that the water temperature in the water tank will not be gradually increased by the water vapor, ensuring the water cooling effect. However, there is no protective mechanism on the outside of the water cooling pipe, and it is not convenient to disassemble. In addition, the furnace body of the equipment is close to the water cooling system, which may cause damage to the water cooling pipe and increase the water temperature, affecting the water cooling effect.

[0024] The upper end of the circulation tube disc 12 is fixedly connected to the radiator 6 through a connecting pipe 10, which is used to reduce the temperature of the hot water flowing out of the circulation tube disc 12. The upper surface of the bottom plate 1 is fixedly connected to a support frame 8, which is used to support the radiator 6 to ensure its stability and safety during operation. The radiator 6 is located on the upper surface of the support frame 8. The right surface of the radiator 6 is fixedly connected to a water tank 7 through a connecting pipe 10, which is used to store cooling water and provide a water source for the entire water cycle. The side surface of the water tank 7 is fixedly connected to a water pump 9 through a connecting pipe 10, which is used to drive water to circulate between the circulation tube disc 12, the radiator 6 and the water tank 7. The water pump 9 and the water tank 7 are both located on the upper surface of the bottom plate 1, and the water pump 9 is located on the left side of the water tank 7.

[0025] Working principle: When the equipment starts to work, the water pump 9 starts to run and draws cooling water from the water tank 7. The output end of the water pump 9 transports the cooling water to the lower end of the circulating tube disc 12 through the connecting pipe 10. The cooling water flows in the circulating tube disc 12 to cover and cool the side surface of the furnace body 11. Since the medium frequency electric furnace generates a lot of heat when working, this heat will be absorbed by the cooling water in the circulating tube disc 12. The cooling water that absorbs the heat flows out through the upper end of the circulating tube disc 12 and flows into the radiator 6 through the connecting pipe 10. The radiator 6 The function is to dissipate the heat in the cooling water to the surrounding environment to reduce the water temperature. The cooling water that has dissipated heat through the radiator 6 flows back to the water tank 7 through the connecting pipe 10 again to complete a cycle. Then, the water pump 9 draws cooling water from the water tank 7 again to start a new round of circulation. In this process, the left protective shell 3 and the right protective shell 2 installed at the circulating tube tray 12 can protect the circulating tube tray 12 and the furnace body 11, and the left protective shell 3 and the right protective shell 2 are connected by hinges and can be opened or closed to maintain or repair the equipment.
