摘要： This application provides an electronic assembly and an electronic device. The electronic assembly includes a circuit board assembly and a liquid cold plate. The circuit board assembly includes a board, a first heat-generating component, and a second heat-generating component, where the first heat-generating component and the second heat-generating component are disposed on the board. The liquid cold plate includes a liquid inlet and a liquid outlet. A cooling working medium flows into the liquid cold plate from the liquid inlet, and flows out of the liquid cold plate from the liquid outlet. The liquid cold plate includes a first cooling region and a second cooling region, where the second cooling region is closer to the liquid outlet than the first cooling region. The cooling working medium first flows through the first cooling region from the liquid inlet, and then flows to the second cooling region. A heat dissipation capability of the first cooling region is stronger than that of the second cooling region. A heat-generating density of the first heat-generating component is greater than that of the second heat-generating component, the first heat-generating component is thermally connected to the first cooling region, and the second heat-generating component is thermally connected to the second cooling region. In this way, a heat dissipation capability of the liquid cold plate is appropriately utilized to improve effects of dissipating heat for the first heat-generating component and the second heat-generating component and also reduce energy consumption.

摘要： A pluggable module is provided, relating to the field of communications device technologies. The pluggable module includes a power control unit (1), an interface unit (2), a monitoring unit (3), and a signal linkage unit (4). The power control unit (1) is connected to the interface unit (2), and the pluggable module can be inserted into an external device by using the interface unit (2). One end of a pull ring (42) is rotatably connected to a bracket (41), and the other end can trigger a signal switch (44). When the pull ring (42) is in an ON state, the signal switch (44) is triggered to send a first switch signal, or when the pull ring (42) is in an OFF state, the signal switch (44) sends a second switch signal. The monitoring unit (3) is configured to control, upon receiving the first switch signal, the power control unit (1) to be powered on, or control, upon receiving the second switch signal, the power control unit (1) to be powered off. In this way, the pluggable module can implement power-on or power-off of the power control unit (1) based on the first switch signal or the second switch signal, thereby implementing hot plugging prevention protection for the pluggable module.
