Patent number: 12058803Abstract: A circuit board assembly is applied to the field of electronic communications technologies to resolve a prior-art heat dissipation problem of a circuit board. The circuit board assembly combines, on a second circuit board, low-speed signals transmitted between a plurality of I/O modules and an IC chip, and then transmits the combined low-speed signals to the IC chip by using a low-speed cable. A low-speed signal sent by the IC chip to the plurality of I/O modules is extended to a plurality of low-speed signals on the second circuit board, and then the plurality of low-speed signals are separately sent to the plurality of I/O modules. This may be applied to a scenario in which a relatively large quantity of electronic components need to be disposed on a circuit board.Type: GrantFiled: September 26, 2023Date of Patent: August 6, 2024Assignee: HUAWEI TECHNOLOGIES CO., LTD.Inventors: Chaojun Deng, Fei Ma, Wei Fang, Zhiwen Yang, Chungang Li, Shun Hao

A first accommodation region of the cabinet body can accommodate a plugboard in a stacked manner, and heat source components of the plugboard dissipate heat through the heat dissipation apparatus. An evaporator, a condenser, and an evaporation pipeline of the heat dissipation apparatus are connected to a liquid return pipeline to form a heat exchange loop, and the evaporator is in thermal contact with an outer surface of a heat source component. The condenser is disposed in a second accommodation region and located above the evaporator. A refrigerant flows in the heat exchange loop, to draw heat of the heat source component far to the condenser, and take away heat of the condenser using air generated by a fan. A second accommodation region is used as an independent air duct whose path is relatively short.Type: ApplicationFiled: January 26, 2023Publication date: July 13, 2023Inventors: Zhiwen YANG, Tao YAN, Jie CHEN, Henglong ZOU, Qingying LIU
