Abstract: A heat dissipation apparatus, a connection structure, and an electronic device. A first heat sink is in thermal contact with a first heat-generating device on a first component, and a second heat sink is in thermal contact with a second heat-generating device on a second component. The first heat sink and the second heat sink are communicated through a pipeline (120), and the three are filled with a cooling medium. Heat generated by either of the first heat-generating device and the second heat-generating device may be transferred to the cooling medium in the heat sink through the corresponding heat sink, and the heat is dissipated outward through a surface of the heat sink.

Abstract: This application provides an optical link fault identification method, and relate to the field of communications technologies. The method includes: obtaining performance data of a network device, extracting a feature parameter of the performance data, and identifying a fault mode on an optical link based on the feature parameter. The method resolves problems of a difficulty in fault identification and slow troubleshooting that are caused by a large quantity of devices, many line faults, and a difficulty in obtaining manual troubleshooting cases. In addition, a fault can be quickly identified when the fault occurs, improving troubleshooting efficiency. When an optical link risk does not cause a fault, deterioration of the performance data can be found in advance based on a feature, to perform identification and warning.
