1. A water cooling device capable of switching a pump loop, comprising:

  • a water tank, having a liquid coolant therein;

    a first pump, having a water inlet connected with a water outlet of the water tank;

    a second pump, having a water inlet connected with the water outlet of the water tank;

    a control unit, being electrically connected to the first pump and the second pump, respectively;

    a shuttle valve, having a main body, the main body having a chamber therein, the chamber including a first axial hole, a second axial hole and an output hole communicating with one another, the first axial hole being connected with the first pump, the second axial hole being connected with the second pump, the chamber being provided with a check valve, the check valve being movable in the chamber and defining a first position and a second position, wherein when the check valve is in the first position, the first axial hole communicates with the output hole, and the second axial hole doesn'"'"'t communicate with the first axial hole and the output hole;

    wherein when the check valve is in the second position, the second axial hole communicates with the output hole, and the first axial hole doesn'"'"'t communicate with the second axial hole and the output hole;

    a water block, connected to the output hole of the shuttle valve;

    a radiator fan, having a first end connected to the water block and a second end connected to the water tank;

    a first loop, wherein when the check valve is in the first position, the water tank, the first pump, the first axial hole of the shuttle valve, the output hole of the shuttle valve, the water block and the radiator fan communicate with one another to form the first loop; and

    a second loop, wherein when the check valve is in the second position, the water tank, the second pump, the second axial hole of the shuttle valve, the output hole of the shuttle valve, the water block and the radiator fan communicate with one another to form the second loop.
