The electric coolant pump is critical to the automotive thermal management system. It comprises a pump assembly, a brushless motor, and a controller. The controller actively propels the brushless motor, which drives the impeller into rotation. Coolant enters through the designated inlet, and aided by centrifugal force, the liquid pressure escalates, promoting the internal circulation of coolant throughout the system’s pipelines. This process significantly enhances the cooling efficiency. A boost in performance and weight reduction translates into improved fuel economy for internal combustion engines and effective cooling in new energy vehicles.
