一种可在线清洗的变频室循环散热系统
本技术涉及变频柜及电气室散热降温领域,特别是涉及一种可在线清洗的变频室循环散热系统。
技术介绍
而高压变频器运行过程中,要产生3~4%的热量损耗。根据行业相关机构对高压变频设备安全的评估报告中显示:在设备故障原因的调查分析中,80%是由于设备运行环境因素所致,其中温度原因占55%、湿度25%、粉尘影响12%、振动和电磁噪声13%;因此变频器周围不能液体、粉尘、油雾、腐蚀性/易燃/爆炸性气体及近距离强震动。粉尘被吸入变频器内电路板上堆积导致绝缘降低、油雾附着在变频器进风滤网上导致滤网堵塞降低冷却进风量,影响发热体散热,使变频器内温度升高。变频单元内电容、电阻等发热器件的高温,都有可能引发着火,发展为火灾或爆炸事故。对于室内散热目前大多采用空调、风机为主,这些散热方式无疑会引入外部的粉尘。因此也有的采用水冷散热,不过水冷散热的方式中,管路中容易产生水垢,其清洗不便。
