[0002] The magnetic energy-saving pump is a fluid conveying device that uses magnetic coupling to achieve shaft seal-free and leakage-free transmission. Its core lies in the mutual attraction of permanent magnets between the inner and outer rotors to transmit torque, so that there is no need for mechanical seals between the pump shaft and the motor, eliminating the risk of shaft seal wear and leakage; at the same time, its low friction loss, no lubrication requirements and efficient magnetic field coupling design make the whole machine have lower energy consumption, longer service life and more reliable operating performance than traditional mechanical seal pumps under medium and low flow and medium and high head conditions. It is widely used in petrochemical, chemical, pharmaceutical and electric power industries that require tight sealing and energy conservation and emission reduction.

[0003] In the prior art, liquid cooling devices often rely on a coolant, and it is impossible to select an appropriate coolant according to the working environment of the liquid cooling device. At the same time, the heat dissipation of the point heat source in the magnetic energy-saving pump only relies on one of the liquid cooling device or the air cooling device. When any heat dissipation device is running at full power, it is impossible to reduce the real-time heat source temperature of the point heat source to the normal working temperature within the minimum heat dissipation time, resulting in demagnetization of the permanent magnet in the point heat source. To this end, the present invention proposes a magnetic energy-saving pump heat dissipation method, equipment and medium. Summary of the invention
