Abstract:
1. A liquid cooling system for a heat generating component, the liquid cooling system comprising: a cooling unit comprising a first cooling body adapted for contacting the heat generating component to absorb heat therefrom, a second cooling body, and a heat sink sandwiched between the first and second cooling bodies, the first cooling body defining a first cavity therein, the second cooling body defining a second cavity therein, the first and second cavities being in flow communication with each other so that coolant is able to flow from the first cooling body to the second cooling body; and a coolant driving unit being in flow communication with the first and second cooling bodies respectively so that the first cooling body, the second cooling body, and the coolant driving unit together form a loop; wherein circulation of the coolant in the loop causes the heat generated by the heat generating component to be capable of being transferred from the first and second cooling bodies to the heat sink for dissipation; wherein the first cooling body comprises a cooling base, and a cover attached to the cooling base and thermally contacting the heat sink, and the first cavity is defined between the cooling base and the cover; wherein the cooling base comprises a cooling plate adapted for absorbing the heat from the heat generating component, and a plurality of sidewalls extending from the cooling plate and cooperatively defining the first cavity; and wherein one of the sidewalls defines a flow inlet port in communication with the first cavity.
