Many efforts have been dedicated to enhancing the near-field radiative heat transfer by designing different kinds of geometric shapes or introducing new materials. Besides just improving the heat transfer rate, active and convenient thermal management is also important in micro/nano thermal systems. We show that introducing an intermediate modulator, based on the graphene/hBN/graphene heterostructure, can enhance and manipulate thermal radiative heat transfer without changing the distance or other parameters of the emitter and absorber. Such three-body systems can increase the radiatively exchanged power several times over corresponding two-body counterparts. The introduced modulator can be viewed as a mid-repeater to effectively enhance photon tunneling through evanescent modes. Furthermore, the heat transfer rate could be modulated in a large range and even be lower than two-body systems by applying bias voltages. The mechanism can be explained by the change of energy transmission coefficients between bodies through adjusting the optical properties of graphene. The presented scheme may open a new avenue to actively control near-field heat transfer at the micro/nanoscales.
