| Abstract: | The paper used the thermal analysis software(Flotherm)based on CFD to thermally simulate the electronic e- quipment SINS,discussed the method and theory on the thermal analysis and analyzed the simulation modes how to be built. It was carried out in detail that the circuit board,the electric device mode and the hot power consumption were de- fined. Under the normal temperature,the temperature field of the system how to be distributed was achieved by making thermal simulation on the electric system in steady state. Compared with the measurement result,the validity of the sim- ulation was verified. As the base of the thermal simulation on the SINS,the result in this paper will play a vital role. |
