A liquid-cooled heat dissipation module for circularly dissipating heat from a heat source. The liquid-cooled heat dissipation module includes a base, a rotor supported by the base and having a hub, a first magnetic part, and a pump having a second magnetic part and a fixed seat. The fixed seat is coupled to the base and has a space to receive the second magnetic part. When the first magnetic part is rotating along with the rotor, the second magnetic part is driven by a magnetic interaction between the first and second magnetic parts so as to generate a circular flow of the working fluid in the pump.
