[0022] Specifically, when the internal temperature of the electric heater body 1 is too high, the outer shell becomes too hot and needs to be cooled. At this time, the heating rod is not energized, and then the water pump 10 transports the cold water in the cooling box 9 to the first heat dissipation fin 6 and the second heat dissipation fin 7 respectively. The cooling water flows along the S-shaped curve direction, takes away the heat absorbed by the first heat dissipation fin 6 and the second heat dissipation fin 7, and then enters the water diversion boxes 20 on both sides respectively, and is sprayed out through the nozzle 21 to cool the outer shell on both sides of the electric heater body 1. At the same time, the water diversion box 20 reciprocates vertically to spray the outer shell evenly. The heated water gathers at the bottom of the rectangular box 15 and finally flows back to the cooling box 9, and is then cooled by the refrigerant and re-enters the cooling cycle. In this process, the fan blades 3 continue to rotate, sucking natural wind into the electric heater body 1 to take away heat. At the same time, the natural wind is cooled by the cooled first heat dissipation fin 6 and the second heat dissipation fin 7, so that the cooled wind enters the electric heater body 1 for further cooling until the outer shell cools to room temperature. The purpose of such design is to accelerate the cooling of the outer shell of the electric heater body 1 through multi-stage cooling methods such as air cooling, cooling water circulation and cooling water spraying, so as to improve the heat dissipation efficiency.

[0027] Further, such as Figure 3 and Figure 4 As shown, the following preferred technical solutions are provided:

[0028] The rectangular box 15 is fixedly connected to the outer wall of the electric heater body 1, and a rectangular groove 16 is opened in the middle of the inner wall of the rectangular box 15. A second motor 18 is fixedly installed on the upper end of the rectangular box 15. The inner bottom surface of the rectangular groove 16 is rotatably connected to a screw rod 17 through a bearing.

[0033] To sum up: when the internal temperature of the electric heater body 1 is too high, the shell becomes too hot and needs to be cooled. At this time, the heating rod is not energized, and then the water pump 10 transports the cold water in the cooling box 9 to the first heat dissipation fin plate 6 and the second heat dissipation fin plate 7 respectively. The cooling water flows along the S-shaped curve direction, takes away the heat absorbed by the first heat dissipation fin plate 6 and the second heat dissipation fin plate 7, and then enters the water separation boxes 20 on both sides respectively, and is sprayed out through the nozzle 21 to cool the shells on both sides of the electric heater body 1. At the same time, the water separation box 20 reciprocates vertically to spray the shell evenly. The warm water gathers at the bottom of the rectangular box 15 and finally flows back to the cooling box 9, and then is cooled by the refrigerant and re-enters the cooling cycle. In this process, the fan blades 3 continue to rotate, and the natural wind is sucked into the electric heater body 1 to take away the heat. At the same time, the natural wind is cooled by the cooled first heat dissipation fin plate 6 and the second heat dissipation fin plate 7, so that the cooled wind enters the electric heater body 1 for further cooling until the shell is cooled to room temperature. The purpose of such design is to accelerate the cooling of the outer shell of the electric heater body 1 through multi-stage cooling methods such as air cooling, cooling water circulation and cooling water spraying, so as to improve the heat dissipation efficiency.
