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: 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. Therefore, an air baffle ring is disposed in the centrifugal fan provided in this application.

IPC: H05K7/20
Abstract: A heat dissipation system includes a first heat dissipation panel, a second heat dissipation panel, a first rotating shaft assembly, a second rotating shaft assembly, and a driving apparatus. The first heat dissipation panel is provided with a first liquid channel, and the first liquid channel includes a first interface and a second interface. The second heat dissipation panel is provided with a second liquid channel, and the second liquid channel includes a third interface and a fourth interface. The first interface is in communication with the third interface through the first rotating shaft assembly, and the second interface is in communication with the fourth interface through the second rotating shaft assembly. The driving apparatus is configured to drive a liquid medium to flow between the first heat dissipation panel and the second heat dissipation panel.

Abstract: A liquid cooling plate includes a housing, a support structure, and a coolant. The housing includes a top wall and a bottom wall, the top wall and the bottom wall are covered to form an accommodation cavity, and the accommodation cavity includes a first region and a second region. The support structure is disposed in the first region and is located between the top wall and the bottom wall. The coolant flows in the accommodation cavity to dissipate heat from a heat generating device, the coolant can expand in volume when being heated and shrink in volume when being cooled, and the second region can deform to absorb a volume variation of the coolant.
