Liquid-cooled Full-power Integrated Converter Performance Features： 1. Integrated structure design · Optimize the design of the outer pipeline to decrease the pipeline length. · The inlet and outlet water pipe are both on the bottom end of the cabinet, can effectively save the installation holes space. · The ingress protection of liquid-cooled machine and converter is the same as IP54, which is easy to use in harsh environment. · The liquid-cooled machine and the converter adopt an integral structure, compact structure, for the convenient transportation and hoisting. 2. Control integration · More accurate detection of water temperature and pressure of the inlet and outlet. · The liquid-cooled machine is controlled by the converter, without the need of external control, so the coordination logic is more excellent. The converter can respond to the abnormal condition of the liquid-cooled machine in time. 3. Maintenance integration · The operation and maintenance of the liquid-cooled system can be monitored by remote network monitoring system. · Unified maintenance by Hopewind, service responses and spare parts reserves are consistent with the converter. · The unified background monitoring software can real-time monitor the operating status of liquid-cooled machine and fault records, to realize the unified customer service inspections.
