Abstract

The invention which belongs to the technical field of protection discloses a compound housing containing liquid metal layers. The housing comprises a housing body and an ablation barrier layer, the liquid metal layers are arranged in the ablation barrier layer or between the housing body and the ablation barrier layer, and at least one liquid metal layer is arranged in the ablation barrier layer. The compound housing containing the liquid metal layers, which is introduced with a liquid metal material having an excellent thermal conduction characteristic, enables the liquid metal layers to be arranged in an upper thermal insulation layer adhered by the outside of the housing, in the ablation barrier layer, in a lower thermal insulation layer, between the upper thermal insulation layer and the barrier layer, between the ablation barrier layer and the lower thermal insulation layer, or between the lower thermal insulation layer and the housing body, so the heat transmission in a normal direction of the compound housing containing the liquid metal layers is reduced, and a cooling effect of ablation barrier layer surface irradiated by laser light spots is realized.

Description

technical field [0001] The invention relates to the technical field of protection, in particular to a composite casing containing a liquid metal layer. Background technique [0002] The damage effects of high-energy laser weapons mainly include thermal ablation damage, shock wave damage and radiation damage. Among them, thermal ablation damage effect is the most common and most likely to occur damage effect. When the laser beam of the high-energy laser weapon is irradiated on the target, the electrons of the material on the surface of the target shell are converted into heat energy due to the collision of the absorbed light energy, which makes the temperature of the material rise rapidly from the surface to the inside. When the material reaches a certain temperature Being melted or even gasified, the resulting vapor expands and splashes outward at a very high speed, and at the same time scours away molten material droplets or solid particles, thereby causing pits or even pe...
