Numerical analysis on heat transfer of laser diode module by equivalent electrical network method

摘要

Because it is complex and inconvenient to use the common temperature field calculating method and experiment method,for analyzing heat transfer properties of laser diode module(LDM) ,an equivalent electrical network method is presented in this paper. Simulation results show that the temperature stability is closely related to ambient temperature,heat sink,LDM current and TEC current. Ambient temperature and TEC controller are the dominant terms effecting on temperature control in practice.
