The invention relates to the technical field of satellite thermal control, in particular to a heat storage device of a micro-nano satellite system, which comprises an outer shell consisting of satellite side plates and a satellite bottom plate, and an air cylinder, a piston, a heat storage bin, a spring and heat insulation plates which are arranged in the outer shell; the piston is arranged in the air cylinder to form a closed space, gas is filled in the closed space, and the piston moves up and down along the wall of the air cylinder; the piston is in an inverted-T shape, and the neck end of the piston is fixedly connected with the heat storage bin. A first heat conduction unit is embedded in each satellite side plate; a second heat conduction unit is embedded in the satellite bottom plate, and the second heat conduction unit is connected with the bottom of the air cylinder; the heat insulation plates are fixedly installed on the two sides of the heat storage bin and slidably attached to the inner walls of the satellite side plates. The two ends of the spring are connected with the satellite bottom plate and the heat storage bin respectively. The temperature change in the satellite is weakened, additional energy supply is not needed, energy consumption is reduced, and normal operation of an in-satellite system in a low-temperature environment is guaranteed.
