The invention relates to a special vehicle body heat insulation structure which comprises a heat-resistant ceramic layer, a fluid heat dissipation layer and a carbon fiber combustion heat insulation layer which are sequentially and fixedly connected from inside to outside, the fluid heat dissipation layer is made of metal materials, and a plurality of fluid channels are formed in the fluid heat dissipation layer in the axial direction; the carbon fiber combustion thermal insulation layer is a porous material which is formed by impregnating phenolic resin into a porous network of carbon fibers and internally contains aerogel, and the pore diameter of gaps in the aerogel is 100 nm to 10 [mu] m. The heat insulation structure has a good heat protection function, and heat protection can be conducted on the internal structure of the special vehicle so that the internal structure can be prevented from being damaged at the high temperature.

    本发明涉及一种特种车辆车体隔热结构,所述隔热结构包括由内向外依次固定连接的耐热陶瓷层、流体散热层以及碳纤维燃烧隔热层,其中,所述流体散热层为金属材料,其内设置有沿轴向的多个流体通道;所述碳纤维燃烧隔热层为将酚醛树脂浸渍到碳纤维的多孔网络中而形成的内部包含有气凝胶的多孔材料,其中,所述气凝胶中的空隙的孔径为100nm至10μm。本发明的隔热结构具有良好的热防护功能,可以对特种车辆内部的结构进行热防护而防止在高温下被损坏。
