Abstract: A heat dissipation device includes a heat-conducting plate having a plate body and a cover mounted to the plate body. The plate body and the cover together define a vapor chamber. At least one partition rib is provided in the plate body to divide the vapor chamber into at least two first partition chambers. A first end of the partition rib is connected to a sidewall of the vapor chamber, and a second end of the partition rib extends into the vapor chamber and is spaced apart from an opposite sidewall of the vapor chamber by a gap. A second partition chamber is formed between the second end of the partition rib and the opposite sidewall and is in fluid communication with the at least two first partition chambers, and the partition rib tapers from the first end towards the second end.

Abstract: Provided are a battery pack and an electric vehicle. The battery pack includes a case, a cooling plate assembly and an energy storage unit. The cooling plate assembly and the energy storage unit are arranged inside the case, and the cooling plate assembly at least includes a first cooling plate. The first cooling plate is fixed on the case, and the first cooling plate divides the case, in a Z-direction, into a first accommodating space which is located above the first cooling plate, and a second accommodating space which is located below the first cooling plate. The energy storage unit at least includes a first energy storage unit which is arranged inside the first accommodating space and fixed on the first cooling plate, and a second energy storage unit which is arranged inside the second accommodating space.

Abstract: This application provides a coverage hole detection method and a related device in the field of communication technologies. If a coverage hole exists between two access point (APs), a terminal passes through the coverage hole when roaming between the two APs. Therefore, a roaming behavior of the terminal between the APs can reflect whether the coverage hole exists between the APs. An electronic device determines, based on a roaming behavior of a terminal between a first AP and a second AP, that a coverage hole exists between the first AP and the second AP. The roaming behavior of the terminal between the first AP and the second AP includes roaming behaviors of a plurality of terminals between the first AP and the second AP.

Abstract: A networking method, a networking apparatus, an electronic device, and a storage medium, are disclosed. The electronic device obtains a networking requirement. The networking requirement includes a scene requirement, a coverage requirement, a device capability requirement, and a matching requirement between upstream and downstream devices. The electronic device obtains a networking structure based on the scene requirement, determines, based on the coverage requirement, the device capability requirement, and the matching requirement, a model of a device at each layer in the networking structure and a quantity corresponding to the model, and connects devices at two adjacent layers in the networking structure to generate a networking solution.

Abstract: A system and method of deploying a master key for a first communication device and second communication device. The first communication device receives a request message from the second communication device through a wireless communication network, and creates a master key algorithm based on configuration parameters of the request message. The first communication device further generates a master key according to the master key algorithm, verifies whether the master key created by the first communication device is correct, and installs the master key in the first and second communication devices when the master key is correct.
