Integrated liquid cooling system for electrical components

A liquid cooling system for a heat generating component, the liquid cooling system comprising:

• a cooling unit comprising 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 sidewalk extending from the cooling plate and cooperatively defining the first cavity;
• wherein the cooling base comprises a plurality of inner walls extending from the cooling plate, and top edges of the inner walls are connected to the cover so that a plurality of flow channels is defined in the first cavity between adjacent inner walls;
• and
• wherein one of the inner walls that is located at a middle portion of the first cavity has a first end spaced from one of opposite sidewalls a distance, and has an opposite second end hermetically connected to the other of the opposite sidewalls, and each of the other inner walls has opposite first and second ends spaced from the opposite sidewalls a distance.
