Flow Field and Temperature Field of Water-Cooling-Type Magnetic Coupling
Abstract At present, the water-cooling simulation of the water-cooled magnetic coupler is based on the water-cooled motor and the hydraulic coupler, which cannot accurately characterize the temperature distribution of the rotating water-cooled coupling of the coupler. Focusing on rotating water cool...
