摘要
高温严重影响电子设备及元器件的有效性和可靠性。散热设计的目的就是为了在电子设备内部以及电子设备和外部环境间设计低热阻通道,将热量及时散出。工业级以太网交换机运行环境恶劣,且可靠性、稳定性、安全性、环境适应性等方面要求高于商业以太网交换机,这对散热设计提出了更高的要求。
High temperatures may seriously affect the validity and reliability of electronic equipment and components. In order to dissipate the heat to the ultimate sink, thermal design need to design low thermal resistance paths both inside the electronic device and between the electronic device and the external environment. Industrial-grade Ethernet switch runs in harsh environment, and the reliability, stability, security, environmental adaptability requirements higher than that of commercial Ethernet switches, these require a higher standard thermal desiga.
