In this paper, the topology optimization method is conducted to aid the design of the fluid channels within a vapor chamber. To analyze the temperature uniformity of a vapor chamber, the channels were simplified as branches with high-conductivity materials, the optimization aimed to minimize the temperature variance in a plate with several high-conductivity branches. Numerical simulations were conducted to analyze the influence of material thermal conductivity ratio and Bi number on the topology of the fluid channel structure. Results showed that the design of topology optimization was feasible and effective.
