Abstract: A vapor chamber includes a housing, a capillary structure, and a working fluid. Both the capillary structure and the working fluid are located in the housing. An area of a surface of the capillary structure in contact with an inner surface of the housing is less than an area of the inner surface. The housing has a cavity. The working fluid in a liquid state is located in the capillary structure. The working fluid in a gaseous state is located in the cavity. The housing includes a first region and a second region. The capillary structure includes a first part located in the first region and a second part located in the second region. The second part includes a trunk structure and a branch structure.

Abstract: A centrifugal fan includes a housing configured to accommodate an impeller. The impeller rotates relative to the housing. A flow channel that cooperates with the impeller is disposed in the housing. The flow channel includes a pressurization area, in which a static pressure and a flow velocity of an air flow are gradually increased along a rotation direction of the impeller. However, an air inlet is disposed on the housing, and there is a specific gap between the impeller and the air inlet. As a result, when air flows through the pressurization area, there is a specific amount of leakage through the gap. Therefore, an air baffle ring is disposed in the centrifugal fan provided in this application.

Abstract: An electronic device includes a fan, a housing, a heat dissipation assembly, and a heat emitting component. The fan, the heat dissipation assembly, and the heat emitting component are disposed in the housing. The fan includes a first side plate and a second side plate. The fan is coupled to the housing through the first side plate and the second side plate. The first side plate, the second side plate, the housing, and the heat dissipation assembly enclose an air outlet channel, and the air outlet channel couples with an air outlet of the fan and an air exhaust vent of the housing.
The first side plate and the second side plate are coupled to the housing such that the first side plate and the second side plate can seal a side gap of the air outlet channel.-

Abstract: A centrifugal fan is disclosed. The centrifugal fan includes a housing, and the housing is configured to accommodate an impeller. The impeller rotates relative to the housing. A flow channel that cooperates with the impeller is disposed in the housing. The flow channel includes a pressurization area. In the pressurization area, a static pressure and a flow velocity of an air flow are gradually increased along a rotation direction of the impeller. However, an air inlet is disposed on the housing, and there is a specific gap between the impeller and the air inlet. As a result, when air flows through the pressurization area, there is a specific amount of leakage through the gap.
