[0002] On medium frequency induction heating equipment, the equipment generates a large amount of heat during operation. The high temperature heat will affect the operating stability of the equipment and even burn out equipment parts.

[0003] At present, the medium frequency induction heating equipment is mainly cooled by a fully enclosed water cooling tower. This fully enclosed water cooling tower has limited cooling capacity and mainly uses external circulating water to take away the heat in the circulating water coil of the equipment and discharge it to the outside.

[0004] When the temperature of the external circulating water is too high, scale will be generated. These scales will adhere to the circulating water coils in the equipment, greatly affecting the cooling effect. In some countries with high outdoor ambient temperature and high humidity, higher cooling capacity is required, which can only be achieved through a larger volume of fully enclosed water cooling tower. For manufacturing companies, every inch of land is valuable, and this fully enclosed water cooling tower is not conducive to enterprise development and scientific and technological progress.
