Abstract:
The present invention provides a liquid cooling heat sink device for cooling a heat source. The liquid cooling heat sink device includes a heat conduction module, a liquid supply module, and a liquid guiding module. The heat conduction module includes a vapor chamber and at least one heat conducting column. The vapor chamber has at least one space and one side of the vapor chamber contacts the heat source. The heat conducting column is mounted on one side of the vapor chamber, and the side of the vapor chamber is distal from the heat source. The liquid supply module is mounted on one side of the vapor chamber and has a casing and a pump. The casing has a liquid entrance terminal and a liquid exit terminal out of the casing. The liquid guiding module is mounted on one side of the vapor chamber and a receiving space is formed between the vapor chamber and the liquid guiding module. The liquid supply module communicates with the receiving space for guiding a coolant to the receiving space and discharges the coolant through the liquid exit terminal. Therefore the heat sink device forms multiple cooling circulating paths for enhancing heat sink efficiency.
