N2 - Equivalent space heat sink for nano-satellite (ESHS-nS) is a space environment simulator applicable to dynamic characteristic ground-testing research of nano-satellite thermal system. In detail the operation principle of ESHS-nS is described, and for the core components thermoelectric cooler (TEC) and force cooling fan, the pulse width modulation (PWM) control strategy and the hardware implementation are proposed. Then, as a platform for a nano-satellite simulator, the ESHS-nS is utilized to carry out ground-testing research on closed-loop temperature control strategy. The results show that ESHS-nS with PWM control can satisfy the requirement of experiment research on nano-satellite temperature control in ground environment, and the ESHS-nS provides a new technical approach for space environment simulation experiment of micro spacecraft thermal systems.
