Abstract
The present invention relates to a water cooling device which comprises a liquid storing shell body having a liquid chamber and a pump having a stator and a rotor. The stator has a coil set disposed electrically on a circuit board. The circuit board and the coil set thereon are both disposed on at least one inner wall of the liquid chamber or integrally overmolded in the liquid storing shell body. The rotor and a propeller oppositely connected to the rotor are received in the liquid chamber and exposed in the cooling liquid. The propeller is provided with a plurality of blades made of metal. At least one magnetic pole region is magnetized on each of the blades opposite to the coil set. Therefore, a thinning effect can be achieved.
Claims14
A water cooling device, comprising:
- a liquid storing shell body having a liquid chamber, an inlet, and an outlet, wherein the liquid chamber communicates with the inlet and the outlet to allow a cooling liquid to flow through the interior thereof;
- and
- a pump used to circulate the cooling liquid and comprising a stator and a rotor, wherein the stator has a coil set disposed electrically on a circuit board, wherein the circuit board and the coil set thereon are both disposed on at least one inner wall of the liquid chamber or integrally overmolded in the liquid storing shell body, wherein the circuit board and the coil set are both isolated from the cooling liquid, wherein the rotor and a propeller oppositely connected to the rotor are received in the liquid chamber and exposed in the cooling liquid, wherein the propeller is provided with a plurality of blades made of metal, wherein at least one magnetic pole region is magnetized on each of the blades opposite to the coil set, wherein the magnetic pole region of the each of the blades is inductively excited by the coil set.
