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.
Claims20
A heat sink, comprising a base board and one or more rib boards, wherein the base board comprises a base board cavity, and each rib board comprises a rib board cavity, wherein
- the base board comprises a first board face and a second board face, the second board face is provided with a plurality of grooves that are in one-to-one correspondence with the one or more rib boards, and a liquid working medium is filled in the base board cavity;
- one end of each rib board is inserted in the base board cavity through a groove corresponding to the rib board, the base board cavity is connected to the rib board cavity of each rib board, each rib board comprises at least one partition board, the at least one partition board separates the rib board cavity into at least two chambers, one end of the partition board is located in the base board cavity, and the at least two chambers are separately connected to the base board cavity;
- when the base board is heated, at least a part of the liquid working medium in the base board cavity is evaporated to a vapor working medium, and then the vapor working medium enters the rib board cavity of at least one of the one or more rib boards;
- and
- the one or more rib boards are configured to condense the vapor working medium, so that the vapor working medium becomes the liquid working medium again and then is refluxed to the base board cavity along the partition board.
The heat sink according to claim 8, wherein a quantity of combining grooves is the same as a quantity of components from which heat is to be dissipated, and the combining grooves are disposed in one-to-one correspondence with the components from which heat is to be dissipated.
A communication device, comprising a component from which heat is to be dissipated and a heat sink, wherein the base board of the heat sink is in contact with the component from which heat is to be dissipated;
- wherein, the heat sink comprises:
- a base board and one or more rib boards, wherein the base board comprises a base board cavity, and each rib board comprises a rib board cavity, wherein
- the base board comprises a first board face and a second board face, the second board face is provided with a plurality of grooves that are in one-to-one correspondence with the one or more rib boards, and a liquid working medium is filled in the base board cavity;
- one end of each rib board is inserted in the base board cavity through a groove corresponding to the rib board, the base board cavity is connected to the rib board cavity of each rib board, each rib board comprises at least one partition board, the at least one partition board separates the rib board cavity into at least two chambers, one end of the partition board is located in the base board cavity, and the at least two chambers are separately connected to the base board cavity;
- when the base board is heated, at least a part of the liquid working medium in the base board cavity is evaporated to a vapor working medium, and then the vapor working medium enters the rib board cavity of at least one of the one or more rib boards;
- and
- the one or more rib boards are configured to condense the vapor working medium, so that the vapor working medium becomes the liquid working medium again and then is refluxed to the base board cavity along the partition board.
