The invention provides a heat insulation device for an avionics system of an unmanned aerial vehicle working on a fire scene, and the heat insulation device comprises an outer layer frame which is used for blocking heat convection and heat radiation of an external fire scene environment and is of an integral sealing structure; the middle-layer heat insulation layer is a combination of a heat insulation material and a cold source and is used for isolating external environment heat from being conducted into the inner-layer cabin body; and the inner-layer cabin body is used for conducting the low temperature released by the middle-layer heat insulation layer to each position in the cabin body. According to the heat insulation device for the unmanned aerial vehicle avionics system working on the fire scene, heat conduction, heat radiation and heat convection of heat of the external fire scene entering the inner cabin body can be effectively reduced. And the working environment of the avionics system of the unmanned aerial vehicle in a fire scene environment is ensured to be within an adaptable temperature range.
本发明提供一种用于火场工作的无人机航电系统的隔热装置,包括外层框架,用于阻断外部火场环境的热对流和热辐射,为整体密封结构;中层隔热层,为隔热材料和冷源的组合,用于隔绝外部环境热量传导进入内层舱体;内层舱体,用于将所述中层隔热层释放的低温传导至舱体内的每个位置。本发明用于火场工作的无人机航电系统的隔热装置,能够有效降低的外部火场的热量进入内层舱体的热传导,热辐射及热对流。保证无人机在火场环境中航电系统工作环境在其可适应的温度范围之内。
