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 compo-nents Through the design and simulation, the working temperature can be kept in the requested tempera-ture 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.
