Liquid-cooling heat dissipating module

A liquid-cooling heat dissipating module, comprising:

• a liquid-cooling radiator comprising a radiator main body, a radiator outlet and a radiator inlet;
• a liquid-cooling head in thermal contact with a heat source, and comprising a head main body, a head outlet and a head inlet;
• a first pipe, wherein two ends of the first pipe are connected with the head outlet of the liquid-cooling head and the radiator inlet of the liquid-cooling radiator, respectively;
• a liquid pump comprising a pump main body, a pump outlet, a pump inlet and an external pump tube, wherein two ends of the external pump tube are connected with the pump outlet of the liquid pump and the head inlet of the liquid-cooling head, respectively;
• a second pipe, wherein two ends of the second pipe are connected with the pump inlet of the liquid pump and the radiator outlet of the liquid-cooling radiator, respectively;
• and
• a shielding cover, wherein at least a part of the liquid pump is sheltered by the shielding cover, so that at least a portion of a sound generated by the liquid pump is obstructed from outputting to surroundings,
• wherein a chamber of the head main body, the first pipe, a chamber of the radiator main body, the second pipe, a chamber of the pump main body and the external pump tube are in fluid communication with each other to define a closed loop, and the shielding cover is isolated from and not in fluid communication with the closed loop.
