Thermal shock resistant phase change heat storage-radiation refrigeration composite material as well as preparation method and application thereof
The invention belongs to the field of heat management of building and outdoor electronic devices, and particularly relates to a thermal shock resistant phase change heat storage-radiation refrigeration composite material and a preparation method and application thereof. The thermal shock resistant phase change heat storage-radiation refrigeration composite material is prepared by coupling a phase change heat storage layer and a radiation refrigeration layer, wherein the phase change heat storage layer is formed by packaging an organic phase change material with a porous carbon material with high thermal conductivity; the radiation refrigeration layer is composed of a polymer electrostatic spinning film; and the coupling is realized by adopting a heat-conducting double-sided adhesive tape. When the composite material is in a low heat flux density, building and outdoor electronic devices can realize a refrigeration effect lower than room temperature due to the radiation refrigeration effect of the composite material; when the heat flux is high, through the dual effects of the composite material, namely the constant temperature effect of the phase change material layer and the heat dissipation effect of the radiation refrigeration layer, heat dissipation of buildings and electronic devices can be achieved, heat accumulation and rapid temperature rise are avoided, and thermal shock resistance is achieved.
本发明属于建筑、室外电子器件热管理领域，具体涉及一种抗热冲击的相变储热‑辐射制冷复合材料及其制备方法和应用。所述抗热冲击的相变储热‑辐射制冷复合材料由相变储热层和辐射制冷层经耦合制得，所述相变储热层由导热性强的多孔碳材料封装有机相变材料组成；所述辐射制冷层由聚合物静电纺丝薄膜组成；所述耦合为采用导热双面胶进行贴合。所述复合材料在低热流密度时，建筑和室外电子器件由于复合材料的辐射制冷的作用，可以实现低于室温的制冷效果；在高热流密度时，通过复合材料的双重功效，即相变材料层的恒温作用和辐射制冷层的散热作用，建筑和电子器件可以实现热量消散，避免热量积累和温度急剧升高，实现抗热冲击性。
