Abstract:
1. A centrifugal pump device adapted for use with a heat-dissipating system, said centrifugal pump device comprising: a motor unit including a motor housing unit, at least two elongated flat stator cores disposed in said motor housing unit and spaced apart from each other, a rotor disposed rotatably in said motor housing unit between said stator cores and rotatable about a rotating axis, and at least two stator windings wound respectively on said stator cores, each of said stator cores extending in a direction perpendicular to and spaced apart from said rotating axis, each of said stator cores cooperating with a corresponding one of said stator windings to constitute a stator unit, each of said stator units having an inner side proximate to said rotor, an outer side distal from said rotor, and opposite first and second lateral sides interconnecting said inner and outer sides, said stator units cooperating with an imaginary first line extending through said first sides and an imaginary second line extending through said second sides to define a between-stator region thereamong; and a pump unit including:
