Abstract: Embodiments of this application relate to a heat dissipation apparatus, a connection structure, and an electronic device. A first heat sink (110a) is in thermal contact with a first heat-generating device (201a) on a first component (200a), and a second heat sink (110b) is in thermal contact with a second heat-generating device (201b) on a second component (200b). The first heat sink (110a) and the second heat sink (110b) 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 (201a) and the second heat-generating device (201b) 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. When heat-generating devices on different components have a specific temperature difference, a heat sink corresponding to a high-temperature heat-generating device transfers heat to a heat sink corresponding to a low-temperature heat-generating device or non-working heat-generating device by using the cooling medium, to implement uniform temperature heat dissipation effect of the first heat-generating device (201a) and the second heat-generating device (201b) on different components. This improves a heat dissipation capability. The heat dissipation apparatus (100) is low-cost, easy to implement, easy to deploy, does not require a large pump body, pipeline, heat exchanger, and the like to be disposed in an equipment room, and does not require additional indoor space.

Abstract: This application relates to a power control method and a relay device. The method includes: A relay device determines a target forwarding power based on a first forwarding power, a second forwarding power, and a third forwarding power, and forwards, by using the target forwarding power, a first signal received from a first device to a second device. The target forwarding power is a lowest power of the first forwarding power, the second forwarding power, and the third forwarding power. The first forwarding power is determined based on an indication of a network device, the second forwarding power is related to an input power of the relay device and a forwarding gain of the relay device, and the third forwarding power is determined based on a maximum forwarding power limit of the relay device. According to the method, the relay device may output a forwarding power matching a capability of the relay device or matching a forwarding power expected by the network device.

Abstract: This application provides a message communication method and a device. In the method, an electronic device determines, in response to a first operation, a first message authentication code based on a message sending time corresponding to the first operation, plaintext content corresponding to the first operation, and a first key corresponding to the electronic device. The electronic device processes the first message authentication code based on a target authentication code length, to obtain a target authentication code. The electronic device generates a target message based on the target authentication code and encrypted plaintext content, and sends the target message to a server. According to the solution, after generating the first message authentication code, the electronic device may process the first message authentication code based on the target authentication code length, to obtain the target authentication code. The target authentication code may be used by the server to perform checking on the received message, and the target authentication code does not occupy excessive resources. Therefore, an amount of information that can be transmitted through message communication is increased when communication security is ensured.
