In this paper, the simulation model of the microchannel vertical tube evaporator and its loop heat pipe system for the backplane cooling is built, and the experimental verification was also completed. The distribution parameter method is used to simulate the performance change of the backplane evaporator and the loop heat pipe system under different working conditions, and the corresponding optimization method is put forward for the low heat transfer efficiency, which provides effective guidance for the optimization design and application of the microchannel vertical tube evaporator.
