Abstract
A water pump housing structure is provided, including a first housing, a second housing, a third housing, a rotor, and a stator. The first housing has an inlet. The second housing, along with the first housing, forms a flow passage. The flow passage is in fluid communication with the inlet and serves as a passage for fluid. The third housing has an inner surface and an outer surface. The inner surface, along with the second housing, forms a stator chamber. A fin structure is formed on the inner surface. The fin structure protrudes from the inner surface toward the stator chamber. The rotor is located inside the flow passage. The stator is located inside the stator chamber and drives the rotor to rotate.
