Application
● Ultra-Fast Charging Equipment Cluster
In high-power charging stacks of 350kW and above, this system continuously dissipates heat accumulated in the charging connector cables, preventing power limitations caused by temperature rise and ensuring peak charging efficiency.
● Special Environment Charging Station
For charging stations in extremely cold permafrost zones or high-temperature desert areas, this system offers -40°C cold start characteristics and 50°C high-temperature heat dissipation capabilities, mitigating the risk of equipment downtime caused by extreme climates.
● Urban Bus Charging Hub
Meeting the continuous operation requirements of electric bus fleets, RS485 networking enables centralized monitoring of multiple cooling systems, significantly reducing the O&M intensity of high-density charging stations.
● Space-Conserving Charging Cabinets
Adaptable to compact cabinets with a depth of up to 330mm, this system achieves maximum heat dissipation efficiency within a limited space by optimizing the layout of the heat exchanger and fan.
