Excessive temperatures can significantly impair the service life and performance of electronic devices, making cooling such devices an increasingly critical issue. This Communication introduces for first time a three-dimensional hydrogel designed effective thermal management. The heat from gateway equipment is absorbed through desorption water molecules within composite hygroscopic material (SHM) encapsulated in gel, leading to remarkable effect. Additionally, material's spontaneous adsorption capability enables self-recovery. Under conditions 80% relative humidity at voltage 5.5 V, 0.35 g (with 5% content) has demonstrated significant effect, achieving temperature reduction up 11.5 °C. represents substantial advancement compared traditional phase change materials (PCM). approach holds broad application prospects future.
