PUMP FOR LIQUID COOLING SYSTEM
First Claim
Patent Images
1. A pump for use with a liquid cooling system, comprising:
- a base;
a case fixed on the base;
a stator embedded into the case;
a rotor unit received between the case and the base, the rotor unit being separated in a liquid-isolating relationship with the stator, comprising;
an inner rotor surrounded by the stator;
an outer rotor surrounding the stator; and
a plurality of blades attached below the inner rotor and the outer rotor for driving the liquid to flow.

Abstract
A pump includes a base (10), a case (20) fixed on the base, a stator (30) embedded into the case, a rotor unit (40) sandwiched between the base and the case. The rotor unit includes an inner rotor (42) surrounded by the stator and an outer rotor (44) surrounding the stator. Magnetic fields produced by the stator have interior parts interacting with the inner rotor, and exterior parts interlinking with the outer rotor. Therefore, the magnetic fields are able to be utilized sufficiently to drive the rotor unit to have a high speed rotation, and an operation efficiency of the pump is enhanced accordingly.

18. A liquid pump, comprising:
-
a casing defining therein a chamber, an inlet and an outlet both being in flow communication with the chamber; a rotor received in the chamber and being rotatable to drive liquid to enter the chamber via the inlet and to exit the chamber via the outlet, the rotor comprising a cylindrical outer wall, a cylindrical inner wall and a substrate connecting with a bottom end of the outer and inner walls, an agitator being formed on a bottom surface of the substrate; an outer magnetic ring embedded in the outer wall of the rotor and an inner magnetic ring embedded in the inner wall of the rotor; a stator received in the chamber to drive the rotor to rotate; a partition seat received in the chamber and arranged between the stator and the rotor to space the stator and the rotor; and a top cover mounted to a top of the casing. - View Dependent Claims (19)
