Unverified弱电箱空间狭小或散热不良时不建议塞入PoE交换机+AC一体机，密闭环境高温会导致设备频繁重启，需预留散热或选低功耗方案87% similarUnverified购买摆放于弱电箱内的交换机需注意机身尺寸和散热：弱电箱空间封闭散热差，优先选低功耗无风扇薄型号，避免长期高温缩短寿命86% similarUnverified不建议为了美观选择尺寸刚好装满断路器的配电箱，散热不良会加速断路器老化并影响载流量，大功率密集回路应选带散热空间的大箱体82% similarUnverified别为省电盲目选半导体：半导体因制冷效率低需长时间持续通电，实际长期耗电未必低于间歇启停的压缩机，且大温差工况下半导体功耗反而更高81% similarUnverified低功率变压器在长时间满载使用时容易发热，使用时需注意散热，避免长时间持续高负载运行80% similar
