Environment-adaptive sliding ring hydrogel temperature-controlled outdoor bench

PendingCN122342506AVapor barrierThermodynamics
This invention relates to the field of urban public facilities technology, specifically to an environmentally adaptive slip ring hydrogel temperature-controlled outdoor bench, comprising a support frame, a temperature-controlled pad, and an internal unidirectional vapor barrier layer, a temperature-controlled layer, a slip ring honeycomb skeleton tube, a buffer layer, and a heat-insulating and moisture-proof base plate. The temperature-controlled layer is filled with hydrogel and a phase change heat storage capsule. A fixing plate is fixedly connected to the bottom side of the temperature-controlled pad, and the fixing plate contains a gradient hydrophilic capillary reflux core. The hydrophilicity of the gradient hydrophilic capillary reflux core gradually increases from the liquid storage cavity to the hydrogel. The air inlet is directly opposite the guide condenser tube. The surface of the slip ring honeycomb skeleton tube has several horizontally oriented sieve holes, and the inner cavity of the slip ring honeycomb skeleton tube is connected to the guide condenser tube. Through the unidirectional vapor barrier layer and the slip ring honeycomb skeleton tube, an effective temperature difference is formed with the steam. The gradient hydrophilic capillary reflux core is used for anti-gravity transport of moisture, realizing closed-loop moisture recycling. The hydrogel combined with the heat storage capsule can meet the outdoor needs throughout the year, and the whole bench is easy to use.
