Its working principle is to use high-intensity permanent magnetic field to strongly excite the free electrons in the heating body to form a high-speed convection current. The existence of this current forms a uniform electromagnetic field on the surface of the heating body, which causes disordered movement inside the heating body and releases a large amount of heat energy. Therefore, compared with traditional heating methods, the heating process of permanent magnet heating is faster and can complete the heating task in a shorter time. In addition, the heating process does not generate radiant heat, has little impact on the environment, and has extremely high energy utilization efficiency.

A temperature sensor and a refilling tube are mounted on the top of the coolant tank 11 respectively. The open port of the refilling tube is externally threadedly connected with a sealing cover. A drain valve tube is mounted on the bottom of the coolant tank 11 to facilitate subsequent replacement. The input end of the water pump 10 passes through the auxiliary bracket 5 and is mounted inside the coolant tank 11.

[0020] Working principle: Embodiment 1 When the permanent magnet heating device body 1 is in use and the permanent magnet assembly 3 needs to be assisted in cooling, the air pump 6 can be started, and the air flow is output from the output end of the air pump 6 to the directional valve pipe 7, and then the air flow passes through the annular sleeve 8 and the ventilation groove 4 to assist in cooling the permanent magnet assembly 3, thereby meeting the cooling requirement of the permanent magnet assembly 3; In order to further improve the auxiliary heat dissipation efficiency of the permanent magnet component 3, the water pump 10 can be started and the solenoid valve in the first solenoid valve tube 13 can be opened during the output operation of the air pump 6, and the coolant in the coolant tank 11 can be pumped to the inside of the extended cooling component 9 by the water pump 10 through the first solenoid valve tube 13, and then, under the gradual expansion of multiple hollow expansion plates 92, the contact area between the airflow and the coolant can be fully guaranteed, and the airflow can be assisted in cooling. Then, the cooled airflow passes through the annular sleeve 8 and the ventilation groove 4 to quickly cool the permanent magnet component 3, thereby improving the cooling efficiency; The used coolant will enter the interior of the rotary box 12 through the return pipe 14, and then enter the coolant tank 11 through the connecting pipe, thus reciprocating and performing a circulation operation.
[0021] Embodiment 2 After the whole device has been used for a certain period of time, when the temperature sensor detects that the temperature of the coolant circulating in the coolant tank 11 exceeds the preset maximum temperature value, the water pump 10 can be started and the solenoid valve in the second solenoid valve tube 15 can be opened during the operation of the permanent magnet heating device body 1, and the water pump 10 pumps the coolant in the coolant tank 11 through the second solenoid valve tube 15 to impact the baffle 163 inside the auxiliary air cooling component 16, and then the baffle 163 synchronously receives kinetic energy and drives the multiple blades 162 to rotate through the transmission shaft 161, and the airflow output by the rotation of the multiple blades 162 cooperates with the first heat sink 17 to quickly self-cool the coolant in the rotary box 12; Then, according to the above-mentioned pumping steps, the coolant inside the coolant tank 11 and the rotary box 12 is circulated and self-cooled through the second solenoid valve pipe 15 and the connecting pipe until the temperature sensor detects that the temperature of the coolant circulating inside the coolant tank 11 is lowered to a specified temperature.
[0022] Embodiment 3 After the whole device is used for a certain period of time, when the temperature sensor detects that the temperature of the coolant circulating in the coolant tank 11 exceeds the preset maximum temperature value, the solenoid valve inside the third solenoid valve tube 18 can be opened during the operation of the permanent magnet heating device body 1. The solenoid valve in the directional valve tube 7 is closed, and then the air flow delivered to the directional valve tube 7 by the air pump 6 is delivered to the interior of the transition cooling tube 19 through the third solenoid valve tube 18, and with multiple second heat sinks 20, the coolant inside the rotary box 12 is non-contactly conducted to dissipate heat, until the temperature sensor detects that the temperature of the coolant circulating in the coolant tank 11 is reduced to a specified temperature.
