Abstract: A heat sink is provided. The heat sink includes a base board and a rib board. The base board includes a base board cavity, and the rib board includes a rib board cavity. The base board includes a first board face and a second board face. A groove is disposed on the second board face. The base board cavity is filled with a liquid working medium. The rib board includes at least one partition board. The at least one partition board separates the rib board cavity into at least two chambers. The at least two chambers are separately connected to the base board cavity. One end of the rib board is inserted in the base board through the groove. One end of the partition board is located in the base board.
