The invention discloses a design method for a load thermal control system for an all-sky monitoring high-energy telescope. The effective load includes a dome cabin and an electronics cabin. The dome cabin is provided with 25 GRD detectors and 6 CPD detectors, and the electronics cabin is provided with 25 GRD detectors and 6 CPD detectors. There are two CPD detectors, and the thermal control system design method includes the following steps: S1. Perform external heat flow analysis, and based on the external heat flow analysis, determine the heat dissipation surface of the entire payload, the dome cabin and the electronics cabin; S2. Independent thermal design with the electronics cabin, and thermal insulation installation for the dome cabin and the electronics cabin; S3. Set up active thermal control electric heaters at the corresponding positions of the payload for heating compensation; S4. For important thermal control products Adopt redundant design and degraded design, and design the maintainability of thermal control products; S5. Establish a reliability mathematical model and conduct reliability analysis on thermal control products; S6. Based on the reliability analysis results of thermal control products, conduct thermal Control system reliability distribution. |
