Jiujiang Tower Outdoor Cabinet Thermal Insulation Renovation Project

To address frequent high-temperature alarms in outdoor color steel rooms, multi-compartment cabinets, and battery swapping cabinets during Jiujiang scorching summers (26–38℃), 2mm aerogel thermal insulation coating was applied to the equipment exteriors, with unmodified units as controls for temperature and energy monitoring. The results were striking: the coated equipment achieved a maximum surface temperature difference of 13℃ in Jiujiang, effectively blocking solar heat gain. Internal temperatures remained stable below 35℃, eliminating overheating alarms that plagued uncoated controls. Additionally, air conditioning energy consumption dropped by around 30%, with a payback period of less than 12 months for two-compartment cabinets.
