随着通讯网络的建设和发展,为解决网络肓区的覆盖、减少投资成本,涌现出大量的户外基站和户外型的通讯设备、供电设备。这些远程通讯设备处于恶劣的外部环境下,它们遭受太阳的热辐射和设备本身发热的影响,消除这两种热源的影响对电子设备的可靠工作至关重要.本文重点介绍户外电源的恶劣环境对设备的影响,机箱设计、散热计算、主动散热、被动散热等技术,以及热交换器的原理.户外电源的结构.采用热交换器方式的优势等内容。
With the construction and development of communication networks, a large number of outdoor base stations and outdoor-type communication equipment and power supply equipment have emerged in order to solve the problem of network coverage and reduce investment costs. These remote communication devices are in harsh external environment, they are subject to the sun’s heat radiation and heat the device itself, eliminating the impact of these two heat sources is essential for the reliable operation of electronic equipment.This article focuses on the harsh environment of outdoor power supply Equipment, chassis design, thermal calculation, active cooling, passive cooling and other technologies, as well as the principle of heat exchanger. Outdoor power supply structure. The advantages of using heat exchangers and so on.
