At the same time, the existence of the iron core plastic body 33 further enhances the effect of the magnetic connection, thereby achieving a high rotor. The design of this electronic water pump effectively prevents the risk of leakage and external contamination by improving the tightness and sealing of the structure. At the same time, the design of the water-cooled heat dissipation cavity 213 not only improves the thermal management efficiency, but also extends the service life of the electronic control board assembly 54 through the water cooling system, so that the electronic water pump can provide stable and efficient water pump performance in a variety of industrial and commercial environments while maintaining a low noise level. In addition, the spin-melting welding method of the water pump shell allows the water outlet position to be freely adjusted 360 degrees, enhancing the product compatibility and user selectivity.
