While providing electrical energy for human society, power equipment also consumes electricity and generate heat. Cooling equipment consumes a significant amount of electricity, further increasing energy consumption and load on the power grid. Therefore, there is an urgent need to develop low-energy and sustainable cooling technologies for power equipment. In this study, a hybrid passive cooling composite designed to enhance heat dissipation for heavy-load power equipment is introduced. Specifically, the composite material achieves outstanding radiative cooling performance with an average solar reflectance of up to 0.98, while its excellent atmospheric water harvesting performance ensures high evaporation cooling power without the need for manual water replenishment. As a result, the composite effectively lowers the temperature of outdoor heavy-load power equipment (e.g., transformers) by 25.3 °C. The excellent heat dissipation properties of the composite make it a powerful tool in safeguarding electrical systems.
