| Abstract: | To ensure the working reliability,assembly of a rubidium atomic clock for space was thermal designed and simulated,considering the support structure and distribution of high-power components Through the design and simulation,the working temperature can be kept in the requested temperature range of the high-power components,as the heat flux is avoided to increase instantaneously. Therefore the thermal reliability of the rubidium atomic clock is ensured. |
