Abstract: In the context of 5G, the high-frequency cyclicity and inhomogeneity of heat flow put forward higher requirements for the thermal control system of electronic devices, and there is a great need for thermal management modules with fixed point and high efficiency to ensure the long-term development of electronic devices. Here, we selected four phase change molecules with significant differences in phase change temperatures to be composited with graphene aerogel (GA) to obtain Ei@GA, Tetra@GA, Octa@GA, and 1,10-Deca@GA. Compared with pure phase change molecules, the thermal conductivity has been increased by more than 20%, and the relative enthalpic efficiency is as high as 98.7% or more. Further, we assembled the four phase change composites by “reduction welding” to obtain the integrated, modular thermal management device M1-PCMs@GA. Simulation of inhomogeneous heat generation in electronics by building an inhomogeneous heat generation platform. Compared with the homogeneous modules M2-Ei@GA and M3-1,10-Deca@GA, the effective temperature control time of the customized module M1-PCMs@GA is extended by 100.0 and 394.3 s, respectively. Therefore, custom-assembled modular thermal management devices have important application prospects in the field of intelligent temperature control of electronic devices, and the idea of cascade assembly enriches the application functions and development direction of intelligent thermal managers.
