Abstract: In order to provide a good environment for the electronic components of the induction magnetometer on orbit, and to protect the equipment against the impact load during the satellite launch process, it is desirable to design an electronic control cabinet with superior thermal, mechanical and anti-radiation performances. A related design for the electronic control cabinet is presented in this paper, which combine the circuit design, the structural design and the thermal design, with optimized system performance. By thermal and mechanical simulations, the design is validated, and it is shown that the structural and thermal designs of the electronic control cabinet can fully meet the relevant index requirements. This design method of the electronic control cabinet for the spaceborne induction magnetometer can also be used for the design of other electronic devices.
