Description

Technical Field

[0001] This article relates to electronic circuit technology, and in particular to a lightweight design method and device for radiation-proof open armor. Background Art

[0002] In radiation environments such as nuclear power plants and space exploration, electronic devices can be damaged by radiation such as gamma rays and X-rays, causing device performance degradation or even failure. Taking nuclear power plants as an example, the radiation dose rate in the reactor building can reach 10 3 Gray / hour (Gy / h), while ordinary electronic devices will 3 Gy, serious performance degradation will occur; in the space environment, the total ionizing dose in geosynchronous orbit may reach 10 5 Rad (rad)(Si), which poses a serious threat to spacecraft electronic systems.

[0003] To ensure the reliable operation of electronic devices in irradiated environments, high-density materials such as lead (Z=82) and tungsten (Z=74) are often used as shielding layers around the electronic devices. The shielding layer absorbs the energy of the radiation, thereby reducing the radiation dose at the location of the electronic devices. In practical applications, the structural design of the shielding layer must comprehensively consider the radiation type, energy range, dose rate level, and the functional requirements of the equipment. For example, in nuclear medicine imaging equipment, sufficient radiation shielding must be ensured while ensuring uncompromised imaging quality. In space probes, optimal radiation protection must be achieved under limited load conditions. In some special application scenarios, such as imaging devices and radiation monitoring equipment in irradiated environments, functional openings such as optical windows and signal transmission channels are required in the shielding armor. Without the protection of shielding materials, these openings become direct radiation channels, significantly reducing shielding effectiveness. These special requirements pose new challenges to the design of radiation shielding structures, requiring refined, intelligent, and customized designs.

[0004] Currently, there are two main approaches to protecting the openings of shielding armor: one is to design the opening path into a curved structure to prevent radiation (without passing through the shielding material) from directly penetrating vulnerable components; the other is to design the shape of the radiation shielding armor to achieve key protection by optimizing the material distribution. However, the design of radiation shielding armor in related technologies is relatively crude, mostly based on empirical material layout, and cannot achieve lightweight design with optimal protection effect. Figure 1This is a schematic diagram of radiation-resistant armor in related technology. This technology uses a folded opening path and a specific armor shape design to optimize the opening. The design has the following features: 1. A metal shielding layer is used to protect against high-energy particles; 2. A folded opening path (reflective light path) is used to prevent direct radiation from entering the device; 3. The armor shape design selects and chooses materials to protect the opening. The above design has the following shortcomings: 1. The layout of the radiation shielding material relies on experience and does not undergo quantitative optimization; 2. It does not involve lightweight design; 3. It can only target radiation sources with a specific spatial orientation, making it difficult to ensure spatial uniformity of the protection effect; 4. It can only target a specific opening path and cannot adjust the solution based on different preset openings; 5. It cannot provide a customized optimal design based on actual working conditions.

[0005] In summary, how to design effective shielding armor openings to improve the reliability of electronic equipment in radiation environments has become a problem to be solved. Summary of the Invention
